What Are the Long-term Outcomes of Locking Plates for Nonosteoporotic Three-part and Four-part Proximal Humeral Fractures With a Minimum 10-year Follow-up Period? Clin Orthop Relat Res 2024; 482:831-840. [PMID: 37874956 PMCID: PMC11008622 DOI: 10.1097/corr.0000000000002895] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Accepted: 09/19/2023] [Indexed: 10/26/2023]
Abstract
BACKGROUND Proximal humeral fractures (PHFs) often occur in elderly individuals who experience low-energy falls. Open reduction and internal fixation (ORIF) of the proximal humerus is typically performed in young, active patients because of their good bone quality and high functional demands. Although good short-term results have been reported after ORIF in young patients, few studies have specifically evaluated long-term outcomes. QUESTIONS/PURPOSES (1) What are the long-term clinical outcomes scores and (2) radiologic outcomes of nonosteoporotic three-part and four-part PHFs treated with locking plates? (3) What complications occurred after treatment, and what factors are associated with poor postoperative functional outcomes scores and avascular necrosis (AVN) of the humeral head after ORIF? METHODS Between June 2005 and December 2012, we surgically treated 774 patients for displaced two-, three-, and four-part PHFs. Approximately 75% (581 of 774) underwent ORIF, 10% (77 of 774) underwent hemiarthroplasty, 7% (54 of 774) underwent intramedullary nailing, 5% (39 of 774) underwent reverse shoulder arthroplasty, and the remaining 3% (23 of 774) underwent other surgical treatments. We considered those who had ORIF as potentially eligible. Based on that criterion, 75% (581) were eligible. However, only patients with nonosteoporotic three- and four-part PHFs (cortical thickness of the proximal humeral diaphysis greater than 6 mm on a preoperative AP radiograph of the affected shoulder) and a minimum of 10 years of follow-up were included. Sixty-four percent (498 of 774) of the patients were excluded because of simple or osteoporotic fractures, 1% (7 of 774) were excluded because of ipsilateral limb multiple fractures, 0.3% (2 of 774) were excluded because of pathologic PHFs, and another 2% (13 of 774) were lost before the minimum study follow-up of 10 years, leaving 8% (61 of 774) for analysis here. The mean age at surgery was 45 ± 12 years, with a mean follow-up of 13 years. Fifty-seven percent (35 of 61) of the patients were men. Patient-reported outcomes were evaluated using the University of California Loas Angeles (UCLA) score (range 0 to 35; higher scores represent better shoulder function) and Constant score (range 0 to 100; higher scores represent better shoulder function) at least 10 years postoperatively. Postoperative radiographs were reviewed to assess the cortical bone thickness of the proximal humerus, neck-shaft angle, head-to-tuberosity distance, and radiologically confirmable complications. Logistic regression analysis was performed to evaluate factors associated with poor postoperative functional scores (UCLA score ≤ 27 or Constant score ≤ 70) and AVN of the humeral head; the association between AVN and postoperative functional outcomes was also assessed. RESULTS At the most-recent follow-up, these patients had a mean UCLA score of 31 ± 3 and a Constant score of 88 ± 10. The mean neck-shaft angle was 133° ± 10°, and 23% (14 of 61) of patients experienced AVN of the humeral head during follow-up. Twenty-nine complications in 30% (18 of 61) of patients were reported. After controlling for potentially confounding variables such as age and gender, we found that the presence of greater tuberosity malposition (odds ratio 18 [95% confidence interval 2 to 167]; p = 0.01) and immediate postoperative neck-shaft angle less than 130° (OR 19 [95% CI 3 to 127]; p = 0.002) were associated with poor postoperative functional scores. Four-part PHFs (OR 13 [95% CI 2 to 82]; p = 0.008) and metaphyseal extension less than 8 mm (OR 7 [95% CI 1 to 35]; p = 0.03) were associated with AVN of the humeral head. For patients who met the criteria for anatomic reduction (achievement of all of the following three criteria: neck-shaft angle ≥ 130°, head-shaft displacement < 5 mm, and head-to-tuberosity distance greater than or equal to 3 mm and less than or equal to 20 mm), there were no differences in postoperative functional scores between patients with AVN and those without. CONCLUSION ORIF of nonosteoporotic proximal humeral fractures with locking plates led to favorable functional and radiologic outcomes at a minimum of 10 years of follow-up. When encountering complex PHFs in patients with good bone quality, every effort must be made to achieve an anatomic reduction of the fracture as far as possible, which may not reduce the risk of AVN (this occurred in nearly one-fourth of patients). However, good outcomes can usually be expected, even in patients with AVN. Because this was a retrospective study with a high risk of bias owing to sparse data, the factors associated with poor postoperative functional outcomes must be further investigated in large prospective studies. LEVEL OF EVIDENCE Level III, therapeutic study.

Bekmezci T, Çepni SK, Demir T. Greater tuberosity medial malposition: does it affect shoulder abductor moment? INTERNATIONAL ORTHOPAEDICS 2024; 48:159-167. [PMID: 37670197 DOI: 10.1007/s00264-023-05967-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 08/30/2023] [Indexed: 09/07/2023]
Abstract
PURPOSE The detrimental effect of greater tuberosity malposition on functional scores is well known. Superior or posterior malpositions exceeding five mm lead to excessive loading on the deltoid strength. However, the significance of situations where greater tuberosity becomes medialized due to the compressive effect of the locking plate fixation, especially in fractures with metaphyseal dead space, has not been emphasized. It is hypothesized that this condition may cause shortening of the rotator cuff moment arm and consequently impact functional scores. METHODS Between 2012 and 2018, 52 patients, aged 65,28 (ranging 40-85) proximal humerus fractures treated with locking plate fixation were included in the study. Cephalodiaphyseal angle, greater tuberosity displacement , patients reported outcome and Constant-Murley scores were evaluated. RESULTS The mean Constant Murley score was determined to be 78.76 (ranging from 38 to 100). According to the patients reported outcome 39 excellent , five good , two fair, six poor results were observed. Avascular necrosis with screw migration was detected in five cases, while one patient experienced implant insufficiency along with varus deformity. Greater tuberosity was found to be positioned between 6 mm posterior-superior and -13 mm medial. Significant medial malposition was observed in three patients, with -9, -12, and -13 mm of medialization, respectively. Cephalodiaphysial angle was determined as 139.30 degrees (ranging from 120 to 150 degrees) and showed weak correlation with the functional score. Greater tuberosity medialization also showed weak correlation with the Constant-Murley score. The values exhibiting deviation were associated with low patient-reported outcome results and functional scores. In the examination of greater tuberosity displacement values, it was observed that Neer type 3 and 4 fractures differed significantly from Neer type 2 fractures regarding to Kruskal-Wallis test. CONCLUSIONS Medial impaction of greater tuberosity may be the reason of decreased functional scores, similar to superior or posterior malposition. The medialization of greater tuberosity should be considered as a potential factor leading to the shortening of the rotator cuff's abductor moment.

Abstract
The aging population is witnessing a steady increase in the incidence of displaced proximal humerus fractures, particularly among elderly patients. Such fractures pose a significant challenge to orthopedic surgeons, given the complex interplay of factors involved, including fracture displacement, comminution, compromised bone quality, and the presence of concurrent medical comorbidities. While open reduction internal fixation (ORIF) remains a viable treatment option for these fractures, it is a technically demanding procedure associated with a high incidence of complications. Recently, reverse total shoulder arthroplasty (RTSA) with tuberosity repair has gained popularity as a successful approach for addressing such fractures. The present case report details a unique and complex case of a chronic four-part proximal humerus fracture, complicated by avascular necrosis of the humeral head, fracture non-union, and hardware penetration. The patient was successfully treated through a reverse shoulder arthroplasty procedure, highlighting the effectiveness of this surgical approach in such challenging scenarios. The advantages of RTSA in this context include the potential to address avascular necrosis, non-union, and hardware complications, as seen in our patient. Additionally, the procedure can restore functional independence and improve the overall quality of life in these challenging cases.

Comparison between osteonecrosis of the humeral and femoral heads - epidemiological analysis of the surgical trend using the nationwide claims database of the republic of Korea. BMC Musculoskelet Disord 2023; 24:878. [PMID: 37951880 PMCID: PMC10638789 DOI: 10.1186/s12891-023-07022-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Accepted: 11/06/2023] [Indexed: 11/14/2023] Open
Abstract
BACKGROUNDS The humeral head is the second most common site of osteonecrosis, after the femoral head. However, compared to osteonecrosis of the femoral head (ONFH), epidemiological information on osteonecrosis of the humeral head (ONHH) is scarce. We hypothesised that different biomechanical properties of the shoulder from the hip joint might present different epidemiological characteristics of ONHH from those of the ONFH. To evaluate epidemiological differences, we compared trends in the surgical treatment of ONHH and ONFH using the nationwide medical claims database of the Republic of Korea (ROK). METHODS We analysed epidemiological data from the Health Insurance Review and Assessment (HIRA) database of the ROK between 2008 and 2018. HIRA database contains almost all medical information in an anonymised form, including demographics, diagnoses, and types of surgical procedures, generated through healthcare practices in ROK. The annual incidence rates of ONHH and ONFH were calculated based on the total number of the general population. Demographics, annual incidence, and the proportion of post-traumatic osteonecrosis and surgical procedures were compared according to the anatomical site and the affected year. RESULTS The total number of patients treated for ONHH and ONFH during the study period was 1,028 and 66,260, respectively. Although the incidence of ONHH increased, it is a relatively rare disease compared to ONFH. ONHH occurred more frequently in females, while ONFH occurred predominantly in male patients (p < 0.001). Surgical treatment for ONHH was most frequently performed in older patients (63.7%), whereas middle-aged patients had the largest proportion of ONFH (48.9%, p < 0.001). The proportion of post-traumatic osteonecrosis was significantly higher in the ONHH (5.1%) than in the ONFH (1.9%, p < 0.001). Arthroplasty was performed more frequently in the ONHH (96.0%) than in the ONFH (92.9%, p < 0.001). CONCLUSION Despite the anatomical similarities between the hip and shoulder joints, the different biomechanical properties, such as weight-bearing functions, might cause epidemiological differences between ONHH and ONFH.

Correct positioning of the calcar screw leads to superior results in proximal humerus fractures treated with carbon-fibre-reinforced polyetheretherketone plate osteosynthesis with polyaxial locking screws. J Orthop Traumatol 2023; 24:54. [PMID: 37816859 PMCID: PMC10564686 DOI: 10.1186/s10195-023-00733-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Accepted: 09/29/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND Plate osteosynthesis with implants made of carbon-fibre-reinforced polyetheretherketone (CFR-PEEK) has recently been introduced for the treatment of fractures of the proximal humerus (PHFs). The advantages of the CFR-PEEK plate are considered to be its radiolucency, its favourable modulus of elasticity, and the polyaxial placement of the screws with high variability of the angle. The primary aim of this study is to investigate the influence of calcar screw positioning on the complication and revision rates after CFR-PEEK plating of PHFs. The secondary aim is to assess its influence on functional outcome. MATERIAL AND METHODS Patients were identified retrospectively. Minimum follow-up was 12 months. The cohort was divided into two groups depending on the distance of the calcar screw to the calcar (group I: < 12 mm, group II: ≥ 12 mm). The range of motion (ROM), Subjective Shoulder Value Score (SSV) and Constant-Murley Score (CS) were analysed at follow-up examination. Subjective complaints, complications (e.g. humeral head necrosis, varus dislocation) and the revision rate were evaluated. RESULTS 51 patients (33 female, 18 male) with an average age of 68.6 years were included after a period of 26.6 months (group I: 32 patients, group II: 19 patients). Apart from the gender distribution, no significant differences were seen in the patient characteristics. The outcome scores showed significantly better clinical results in group I: SSV 83.4 vs 71.2, p = 0.007; CS 79.1 vs 67.8, p = 0.013. Complications were seen less frequently in group I (18.8 % vs 47.4 %, p = 0.030). CONCLUSION This study shows that the positioning of the calcar screw is relevant for CFR-PEEK plate osteosynthesis in PHFs with a good reduction of the fracture. Optimal positioning of the calcar screw close to the calcar (< 12 mm) is associated with a lower rate of complications, resulting in significantly superior functional outcomes.

Abstract
BACKGROUND Proximal humerus fracture dislocations, excluding 2-part greater tuberosity fracture dislocations, are rare injuries. Outcomes after open reduction and internal fixation (ORIF) of these injuries have not been well described in the literature. The purpose of this study was to report the radiographic and functional outcomes of patients who underwent ORIF of a proximal humerus fracture dislocation. METHODS All skeletally mature patients who underwent ORIF of a proximal humerus fracture dislocation between 2011 and 2020 were identified. Patients with isolated greater tuberosity fracture dislocations were excluded. The primary outcome was American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score at a minimum of 2 years. Secondary outcomes were the development of avascular necrosis (AVN) and reoperation rate. RESULTS Twenty-six patients met the inclusion criteria. The mean age was 45 years (standard deviation 16), and 77% were men. Median time to reduction and surgery was 1 day (interquartile range [IQR] 1-5). There were 2 (8%) Neer 2-part fractures, 7 (27%) 3-part, and 17 (65%) 4-part fractures. Fifty-four percent (54%) involved the anatomic neck and 31% included a head-split component. Thirty-nine percent (39%) were anterior dislocations. The rate of AVN was 19%. The reoperation rate was 15%. Reoperations included removal of hardware (2), subscapularis repair (1), and manipulation under anesthesia (1). No patients went on to arthroplasty. ASES scores were available for 22 patients (84%) including 4 of 5 patients with AVN. The median ASES score at a mean of 6.0 years postoperatively was 98.3 (IQR 86.7-100, range 63.3-100) and was not different in those with or without AVN (median 98.3 vs. 92.0, P = .175). Only the presence of medial comminution and nonanatomic head shaft alignment on postoperative radiographs were associated with increased risk of AVN. CONCLUSION Radiographic rates of AVN (19%) and reoperation (15%) were high in this series of patients undergoing ORIF of proximal humerus fracture dislocations. Despite this, none of the patients required arthroplasty, and patient-reported outcome scores at an average of 6 years postinjury were excellent, with a median ASES score of 98.5. ORIF should be considered as primary method of treatment in proximal humerus fracture dislocations not only in young patients but also middle-aged patients.

Abstract
OBJECTIVE Restoration of the medial support is especially important for the treatment of proximal humeral fractures. The objective of this study was to investigate the radiographic and clinical outcomes of intramedullary nail fixation with a special focus on the presence of calcar comminution. METHODS In this retrospective study of patients with displaced proximal humeral fractures that were treated by intramedullary nail between January 2018 and July 2021, fracture morphology and the calcar integrity were noted on preoperative radiographs. Patients were divided into two groups according to calcar integrity. During follow-up, radiological assessment and functional outcome, including the deltoid tuberosity index (DTI), neck shaft angle (NSA), visual analog scale (VAS), the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST) score, active and passive range of motion, were performed. A Student t-test and univariate logistic regression analysis was used. RESULTS A total of 83 patients (54 female, 29 male) had complete follow-up (average, 12.8 months; range, 10 to 33 months) and functional assessment in our study. The average age was 58.6 years (range, 20 to 89 years). The mean loss of NSA was 4° (range, 0°-12°) and no significant difference was found between two groups (p = 0.27). DTI had an average of 1.50 ± 0.19 (range 1.13-2.04). Patients with intact calcar achieved greater range of forward elevation (129.06 ± 11.91 vs. 121.05 ± 11.97, p = 0.01), and higher SST scores (8.61 ± 1.85 vs. 7.37 ± 2.22, p = 0.02). Two groups showed similar outcomes in VAS, ASES score, and range of abduction. One patient demonstrated a proximal interlocking screw cutting through and osteonecrosis of the humeral head, who underwent a second surgery for screw removal. There were no cases of infection, malunion, nonunion, nerve injury, subacromial impingement, or rotator cuff tear during the study period. CONCLUSION Intramedullary nail can favorably be used to manage proximal humeral fractures with good early radiographic and functional outcomes, even for those with comminuted calcar.

Abstract
BACKGROUND Open reduction and plate osteosynthesis are considered as a successful technique for the treatment of proximal humerus fracture (PHF) despite high complication rates. The objective of our study was to review the clinical outcome and complications of the Anatomic Locking Plate System (ALPS) and compare it to the Proximal Humeral Internal Locking System (PHILOS). Our hypothesis was that ranges of motion (ROM) were superior and complication rates were lower with ALPS. METHODS Twenty patients treated with ALPS for PHF were retrospectively compared to 27 patients treated with PHILOS. Union, ROM and complications were clinically and radiologically assessed at 6 weeks, 3, 6, 12 and 18-24 months post-operatively. RESULTS Mean age was 52 ± 14 in the ALPS group and 58 ± 13 in the PHILOS group. Last follow-ups were conducted at a mean of 20.6 ± 4.8 months. Mean shoulder abduction was superior with ALPS by 14° (p-value = 0.036), 15° (p-value = 0.049), and 15° (p-value = 0.049) at 3, 6, and 12 months respectively. Mean shoulder external rotation was superior with ALPS by 11° (p-value = 0.032), 15° (p-value = 0.010) and 12° (p-value = 0.016) at 6 weeks, 3 and 6 months respectively. At the end of the follow-up, ROM remained better with ALPS, but not significantly. Complication rates over 21 months reached 20% with ALPS and 48% with PHILOS (p-value = 0.045). Implant removal rates reached 10% with ALPS and 37% with PHILOS (p-value = 0.036). Avascular necrosis was the only cause for hardware removal in the ALPS group. CONCLUSION The ALPS group showed better clinical outcomes with faster recovery in abduction and external rotation, although no difference in ROM remained after 21 months. Additionally, the complications rate was lower at last follow up. In our experience, the ALPS plating system is an effective management option in some PHF.

It Is Always the Same—A Complication Classification following Angular Stable Plating of Proximal Humeral Fractures. J Clin Med 2023; 12:jcm12072556. [PMID: 37048639 PMCID: PMC10095119 DOI: 10.3390/jcm12072556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2023] [Revised: 03/19/2023] [Accepted: 03/22/2023] [Indexed: 03/31/2023] Open
Abstract
Introduction: The aim of this study was to create a novel complication classification for osteosynthesis-related complications following angular stable plating of the proximal humerus subsuming the influence of these complications on clinical outcome in relation to fracture morphology and consequent revision strategies. A total of 1047 proximal humerus fractures with overall 193 osteosynthesis-associated complications (24.5%) were included. The following complication types could be clarified: complication Type 1 is defined by mild varus (<20°) or valgus displacement of the humeral head without resulting in a screw cutout through the humeral head cortex. Type 2a is defined by varus displacement (<20°) of the humeral head associated with screw cutout through the humeral head cortex. Type 2b complication is limited to displacement of the greater tuberosity, lesser tuberosity, or both tuberosities. Complication Type 2c is defined by severe varus dislocation (>20°) of the humeral head with screw cutout at the humeral head cortex. Complication Type 3 describes a displacement of the angular stable plate in the humeral shaft region with associated shaft-sided screw cutout, while the position of the humeral head remains static. Complication Type 4 is characterized by the occurrence of AVN with or without glenoidal affection (4a/b). Clinical outcome according to the constant score was mainly affected by type 2–4, leading to a deteriorated result. Depending on the type of complication, specific revision strategies can be considered. Additionally, more complex fracture patterns fostered the incidence of complications.

The Hertel classification can't predict the risk of humeral head osteonecrosis after osteosynthesis using an anterolateral approach. Clinics (Sao Paulo) 2023; 78:100173. [PMID: 36871503 PMCID: PMC10009436 DOI: 10.1016/j.clinsp.2023.100173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2022] [Revised: 01/07/2023] [Accepted: 02/08/2023] [Indexed: 03/06/2023] Open
Abstract
BACKGROUND Proximal humeral fractures can progress to osteonecrosis of the humeral head. Hertel developed a binary classification system (12 subtypes) and demonstrated that some patterns have more risk to develop osteonecrosis. Hertel described the prevalence and the risk factors for Humeral head osteonecrosis after osteosynthesis using a Deltopectoral approach. Few studies have evaluated the prevalence and the capacity of Hertel's classification to predict Humeral Head osteonecrosis following osteosynthesis of proximal Humeral fractures through the anterolateral approach. The objectives of this study were to correlate osteonecrosis predictors established by the Hertel classification with the risk of developing osteonecrosis and its prevalence after osteosynthesis using the anterolateral approach. METHODS This was a retrospective study of patients who underwent osteosynthesis of proximal humerus fractures using an anterolateral approach. Patients were divided into two groups: high risk for necrosis (group 1) and low risk for necrosis (group 2) according to Hertel's criteria. The overall prevalence of osteonecrosis and the prevalence in each group were calculated. A radiological examination was performed in the true anteroposterior (Grashey), scapular, and axillary views, before and after the operation (minimum 1 year after surgery). A Kaplan-Meier curve was used to assess the pattern of the temporal evolution of osteonecrosis. The groups were compared using the Chi-square test or Fisher's exact test. The unpaired t-test (parametric variables - age) and the Mann-Whitney test (non-parametric time between trauma and surgery) were used. RESULTS In total, 39 patients were evaluated. The postoperative follow-up time was 14.5 ± 3.3 months. The time to onset of necrosis was 14.1 ± 3.9 months. Sex, age, and time between trauma and surgery did not influence the risk of necrosis. Type 2, 9, 10, 11, and 12, or fractures with posteromedial head extension less than or equal to 8 mm, or diaphysis deviation greater than 2 mm, as well as grouping did not influence the risk for osteonecrosis. CONCLUSIONS Hertel's criteria were not able to predict the development of osteonecrosis after osteosynthesis of proximal humerus fractures performed through the anterolateral approach. The total prevalence of osteonecrosis was 17.9% with a tendency toward an increased incidence after 1 year of surgical treatment.

Computed Tomography Does Not Improve Intra- and Interobserver Agreement of Hertel Radiographic Prognostic Criteria. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58101489. [PMID: 36295650 PMCID: PMC9612020 DOI: 10.3390/medicina58101489] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/17/2022] [Revised: 10/06/2022] [Accepted: 10/17/2022] [Indexed: 11/23/2022]
Abstract
Background and Objectives: Proximal humerus fractures are the second most frequent site of avascular necrosis (AVN), occurring in up to 16% of cases. The Hertel criteria have been used as a reference for the prediction of humerus head ischemia. However, these are based solely on the use of radiographs, which can make interpretation extremely difficult due to several reasons, such as the overlapping fragments, severity of the injury, and noncompliant acute pain patients. The objectives of the study were to evaluate the role of computed tomography (CT) in the interpretation of the Hertel criteria and to evaluate the intra- and interobserver agreement of orthopedic surgeons, comparing their area of expertise. Materials and Methods: The radiographs and CT scans of 20 skeletally mature patients who had fractures of the proximal humerus were converted to jpeg and mov, respectively. All images were evaluated by eight orthopedic surgeons (four trauma surgeons and four shoulder surgeons) in two different occasions. The intra- and interobserver agreement was assessed by using the Kappa coefficient. The level of significance was 5%. Results: There was a weak-to-moderate intraobserver agreement (κ < 0.59) for all examiners. Only the medial metaphyseal hinge greater than 2 mm was identified by 87.5% of evaluators both in the radiographic and CT examinations in the two rounds of the study (p < 0.05). There was no significant interobserver agreement (κ < 0.19), as it occurred only in some moments of the second round of evaluation. Conclusions: The prognostic criteria for humeral head ischemia evaluated in this study showed weak intra- and interobserver agreement in both the radiographic and tomographic evaluation. CT did not help surgeons in the primary interpretation of Hertel prognostic criteria used in this study when compared to the radiographic examination.

Abstract
BACKGROUND The treatment of proximal humerus fracture dislocations can be challenging given the extensive injury to the proximal humeral anatomy and increased risk of devascularization of the humeral head often seen in these injuries. The purpose of this study is to undertake a systematic review of the literature on the functional outcomes, rate of revision, and short- and long-term complications for proximal humerus fracture dislocations treated with open reduction and internal fixation (ORIF). METHODS The PubMed and OVID Embase databases were queried for literature reporting on proximal humerus fracture dislocations treated with ORIF. Data including study design, patient demographics, functional outcomes, and complications were recorded. RESULTS Twelve studies including 294 patients with Neer type 2-, 3-, or 4-part proximal humerus fracture dislocations met the criteria for inclusion. The mean patient age was 53.4 years (19-89 years) with an average follow-up of 2.9 years (1.15-4.9 years). At the final follow-up, the mean Constant score was 73.2 (52-87.3) and the mean Disabilities of the Arm Shoulder and Hand score was 26.6 (17.5-32). Avascular necrosis was observed in 20.0% (0%-82.3%) and nonunion was observed in 3.0% (0%-7.7%) of patients. Conversion to arthroplasty was observed in 10.7% (5%-20%) and a total reoperation was observed in 35.6% (11.8%-89.1%) of patients in studies explicitly reporting these outcomes. In addition to conversion to arthroplasty, common causes of reoperation were revision ORIF (5.2%) and hardware removal (22.2%). CONCLUSION Patients undergoing ORIF for proximal humerus fracture dislocations have reasonable functional outcomes but relatively high avascular necrosis and reoperation rates. This information can be used to counsel patients and set expectations about the potential for further surgeries.

Abstract
BACKGROUND Humerus fractures play a major role in daily clinical routine, and subsequent osteonecrosis is common after osteosyntheses. OBJECTIVES The current paper highlights the incidence and cause of osteonecrosis after proximal humerus fractures, with respect to presentation of anatomy and risk factors. METHODS Display of the literature and therapy options for humerus fracture and subsequent necrosis. RESULTS Humerus fractures are the seventh most frequent fractures in humans. The complication rate is 40%, and the described rate of necrosis is up to 34%. Accordingly, the surgical revision rate is at 19% according to recent literature. CONCLUSION The treatment of humerus head fracture must consider numerous variables. The individual type of fracture and the current individual situation of the patient must be included in the process of choosing the right treatment. Modern implants with screw locking features should be used, and for certain circumstances the direct implantation of a prosthesis should be considered. Thereby the expectations of the patient with respect to the postoperative activity level play a major role.

What Factors Are Associated With Poor Shoulder Function and Serious Complications After Internal Fixation of Three-part and Four-part Proximal Humerus Fracture-dislocations? Clin Orthop Relat Res 2022; 480:1566-1573. [PMID: 35333197 PMCID: PMC9278935 DOI: 10.1097/corr.0000000000002190] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/11/2021] [Accepted: 03/07/2022] [Indexed: 01/31/2023]
Abstract
BACKGROUND Three-part and four-part fracture-dislocations of the proximal humerus are characterized by severe soft tissue disruptions that can compromise the viability of the humeral head. As a result, nonunion and avascular necrosis are more common in these injuries. In such injuries, surgical treatment (internal fixation or arthroplasty) is performed in most patients who are determined to be fit for surgery to potentially restore shoulder function. Although the decision to preserve or replace the humeral head is simple in young patients or those > 65 years, in most other patients, the decision can be complicated, and little is known about which patient-related and injury-related factors may be independently associated with poor shoulder function or complications like avascular necrosis. QUESTIONS/PURPOSES (1) What proportion of fractures united after internal fixation of a three-part or four-part fracture-dislocation of the proximal humerus, what is the mean Constant score at a minimum of 2 years after this injury, and what proportion had serious complications (such as loss of fixation, nonunion, reoperation, or avascular necrosis)? (2) After controlling for potential confounding variables, what factors are independently associated with poor shoulder function (defined as a Constant score < 55 out of 100) and occurrence of serious complications such as loss of fixation or reduction resulting in revision surgery, nonunion, or radiographic evidence of avascular necrosis of the humeral head? METHODS Between 2011 and 2017, the senior author of this study (ASG) treated 69 patients with three-part or four-part proximal humerus fracture dislocations. During this time, indications for internal fixation in these patients were adequate humeral bone quality as determined by the surgeon on radiographs, adequate bone stock and volume available for fixation in the humeral head as determined on CT images, and the absence of a head split component as assessed on preoperative radiographs and CT images. On this basis, 87% (60 patients) underwent internal fixation with a locked plate and suture fixation of the tuberosities through a deltopectoral approach. Thirteen percent (nine patients) underwent either a hemiarthroplasty or a reverse total shoulder arthroplasty. Of the 60 patients who underwent internal fixation, four declined to participate in the study and two with brachial plexus palsy were not considered for inclusion. This study focused on the remaining 54 patients who were considered potentially eligible. To be included, a minimum follow-up of 2 years was required; 11% (6 of 54) were lost before that time, and the remaining 48 patients were analyzed at a mean of 48 months ± 17 months in this retrospective study, which drew data from longitudinally maintained institutional databases. Fracture union was assessed by obliteration of fracture lines and the presence of bridging trabecular bone on plain radiographs. Shoulder function was assessed using the Constant score, which is scored from 0 to 100 points, with 0 indicating the most disability and 100 the least disability. The anchor-based minimal clinically important difference for the Constant score is 9.8 points. Twelve patient-related and injury-related factors were analyzed using a multivariate regression model to identify factors that are independently associated with poor results after internal fixation as measured by shoulder function and the occurrence of serious complications. We categorized results as poor if patients had one or more of the following: Constant score < 55 out of 100 at the last follow-up examination (for patients who underwent revision surgery, the Constant score immediately before revision was considered) and loss of fixation or reduction resulting in revision surgery, nonunion, or avascular necrosis of the humeral head. Patients were screened for avascular necrosis at 6 and 12 months after surgery, then annually for another 2 years. Further assessments were made only based on symptoms. RESULTS Seventy-nine percent of the fractures united within 18 weeks of surgery (38 of 48), and an additional 13% united by 24 weeks (6 of 48), while 8% did not unite (4 of 48). The mean Constant score at the last follow-up was 68 ± 12. Twenty-one percent (10 of 48) had a Constant score < 55, indicating poor shoulder function. Twenty-one percent (10 of 48) experienced avascular necrosis, and 15% (7 of 48) with either nonunion or avascular necrosis underwent revision shoulder arthroplasty. Two patients who underwent arthroplasty had both nonunion and avascular necrosis. After controlling for potentially confounding variables, we found that being a woman (odds ratio 1.7 [95% confidence interval 1.4 to 2.1]; p = 0.01), four-part fracture dislocations (OR 2.1 [95% CI 1.5 to 2.7]; p < 0.001), absence of a metaphyseal head extension (OR 2.4 [95% CI 1.8 to 3.3]; p < 0.001), absence of active back-bleeding from the humeral head (OR 3.4 [95% CI 2.3 to 5.1]; p < 0.001), height of the head segment < 2 cm (OR 2.3 [95% CI 1.8 to 2.8]; p < 0.001), and absence of capsular attachments to the head fragment (OR 2.2 [95% CI 1.6 to 2.9]; p < 0.001) were independently associated with poor shoulder function and the occurrence of complications such as nonunion and avascular necrosis. CONCLUSION Internal fixation of three-part and four-part proximal humerus fracture dislocations resulted in poor shoulder function and complications in a high number of patients, although fracture union was achieved in most patients. A nonunion proportion of 8%, 21% proportion of avascular necrosis, and 15% proportion of patients who underwent revision surgery suggests this is a fairly terrible injury. Being a woman and injury factors such as four-part fracture dislocation, absent metaphyseal head extension and back-bleeding from the head, height of the fractured head segment < 2 cm, and absence of capsular attachments to the head were independently associated with poor function and complications. Our findings can help surgeons decide between internal fixation and arthroplasty for the surgical treatment of these injuries in patients across different age groups and functional demands. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Background Angular stable plates were introduced two decades ago as a promising treatment for fixation of displaced fractures of the proximal humerus (PHF). However, high rates of adverse events and reoperations have been reported. One frequent reason is secondary penetration of screws into the glenohumeral joint, due to sinking of the fracture or avascular head necrosis. To prevent joint penetrations angular stable plates with smooth locking pegs instead of locking screws have been developed. The aim of the present study was to investigate whether blunt pegs instead of pointed screws reduced the risk of secondary penetration into the glenohumeral joint during fracture healing after operatively treated PHFs. Methods From two different patient cohorts with displaced PHFs (60 treated with PHILOS plate with screws and 50 with ALPS-PHP plate with pegs), two groups were matched according to fracture type AO/OTA 11-B2 and 11-C2 and age (55–85 years). They were followed up at 3, 6 and 12 months. Primary outcome was radiographic signs of peg or screw penetrations into the glenohumeral joint at 12 months. Secondary outcomes were Oxford shoulder score (OSS) and Constant Score (CS) and radiographic signs of avascular humeral head necrosis (AVN). Results Eighteen PHILOS patients with B2 and C2 fractures could be matched with a corresponding group of 18 operated with ALPS-PHP with pegs. The number of penetrations of pegs and screws were equal between the two groups and the development of avascular head necrosis did not differ either. The functional outcomes for both OSS and CS at 12 months was clearly in favor of patients without joint penetrations in both groups. Conclusion We found no differences in the number of screw or peg penetrations in the PHILOS and ALPS-PHP group and the occurrence of AVN was equal. Joint penetrations led to inferior functional outcomes at 1 year. The ClinicalTrials.gov identifier 20/11/12 prospectively for the Philos Group is NCT01737060, and for the ALPS group 11/03/20 retrospectively is NCT04622852.

Abstract
PURPOSE To evaluate the potential of locking compression plate with intramedullary fibular allograft in managing proximal humeral fractures with an unstable medial column. METHODS Between March 2007 and March 2015, we retrospectively analyzed 63 patients who underwent locking plate fixation for proximal humeral fracture with an unstable medial column. All patients were assigned into group 1 (patients treated with locking plate) and group 2 (patients treated with locking plate with intramedullary fibular allograft). Groups 1 and 2 were composed of 29 and 34 patients, respectively. We analyzed bone union, the neck-shaft angle, the Constant score, the range of motion, and complications. RESULTS The mean average bone union time of the patients was 13.9 weeks in group 1 and 11.3 weeks in group 2. The average Constant score was 67.4 in group 1 and 73.6 in group 2 (p < 0.05). The mean preoperative NSA, postoperative NSA, and NSA at the last follow-up were 104.4°, 125.8°, and 115.8°, respectively, in group 1, and 109.0°, 130.3°, and 127.1°, respectively, in group 2. The mean forward flexion, abduction, external rotation, and internal rotation were 109.0°, 48.2°, 34.0°, and L5, respectively, in group 1, and 127.5°, 118.2°, 38.7°, and L1, respectively, in group 2. In group 1, avascular necrosis occurred in one patient and screw cutout in two patients. In group 2, screw cutout occurred in one patient. CONCLUSION In patients aged over 65 years with proximal humeral fractures, an unstable medial column was associated with poor clinical results owing to varus collapse. To prevent this, an intramedullary fibular allograft was used, and radiologic and clinical results were better with this approach than with a locking plate alone. Therefore, locking plate fixation using a fibular allograft is one of the possible treatments for patients with an unstable medial column.

Abstract
BACKGROUND Avascular necrosis is a delayed complication of proximal humerus fractures that increases the likelihood of poor clinical outcomes. CT scans are routinely performed to guide proximal humerus fracture management. We hypothesized iodine concentration on post-contrast dual energy CT scans identifies subjects who develop avascular necrosis and ischemia due to compromised blood flow. MATERIALS AND METHODS 55 patients with proximal humerus fractures enrolled between 2014 and 2017 underwent clinical, radiographic and contrast enhanced dual energy CT assessment. Iodine densities of the humeral head and the glenoid (control) were measured on CT. Subjects managed with open reduction internal fixation or conservatively (non-surgical) were followed for up to two years for radiographic evidence of avascular necrosis. Arthroplasty subjects underwent histopathologic evaluation for ischemia of the resected humeral head. RESULTS 17 of 55 subjects (30.9%) were treated conservatively, 21 (38.2%) underwent open reduction internal fixation and 17 of 55 (30.9%) underwent arthroplasty. Of the 38 subjects treated conservatively or with ORIF, 20 (52.6%) completed 12 months of follow up and 14 (36.8%) 24 months of follow up. At 12 months follow up, two of 20 subjects (10%) and at 24 months 3 of 14 subjects (21.4%) developed avascular necrosis. At 12 months, the mean humerus/glenoid iodine ratio was 1.05 (standard deviation 0.24) in subjects with AVN compared to 0.91 (0.24) in those who did not. At 24 months, subjects with avascular necrosis had a mean humerus/glenoid iodine concentration ratio of 1.06 (0.17) compared to 0.924 (0.21) in those who did not. Of 17 arthroplasty subjects, 2 had severe ischemia and an iodine ratio of 1.08 (0.30); 5 had focal ischemia and a ratio of 1.00 (0.36); and 8 no ischemia and a ratio of 0.83 (0.08). CONCLUSIONS Quantifying iodine using dual energy CT in subjects with proximal humerus fractures is technically feasible. Preliminary data suggest higher humeral head iodine concentration may increase risk of avascular necrosis; however, future studies must enroll and follow enough subjects managed with open reduction internal fixation or conservatively for two or more years to provide statistically significant results.

Abstract
PURPOSE To assess longer-term (> 5 years) function and outcome in patients treated with anatomic locking plates for proximal humerus fractures. METHODS This retrospective cohort study was conducted at an urban, academic level 1 trauma center and an orthopedic specialty hospital. Patients treated operatively for proximal humerus fractures with an anatomic locking plate by three orthopedic trauma surgeons and two shoulder surgeons from 2003 to 2015 were reviewed. Patient demographics and injury characteristics, disabilities of the arm, shoulder, and hand (DASH) scores, complications, secondary surgeries, and shoulder range of motion were compared at 1 year and at latest follow-up. RESULTS Seventy-five of 173 fractures were eligible for analysis. At a minimum 5 years and a mean of 10.0 ± 3.2 years following surgery, DASH scores did not differ from one-year compared to long-term follow-up (16.3 ± 17.4 vs. 15.1 ± 18.2, p = 0.555). Shoulder motion including: active forward flexion (145.5 vs. 151.5 degrees, p = 0.186), internal rotation (T10 vs. T9, p = 0.204), and external rotation measurements (48.4 vs. 57.9, p = 0.074) also did not differ from one year compared to long-term follow-up. By one year, all fractures had healed. After 1-year post-operatively, four patients underwent reoperation, but none for AVN or screw penetration. CONCLUSIONS Patient-reported functional outcome scores and shoulder range of motion are stable after one year following proximal humerus fracture fixation, and outcomes do not deteriorate thereafter. After one-year, long-term follow-up of fixed proximal humerus fractures may be unnecessary for those without symptoms.

Abstract
PURPOSE Post-traumatic osteonecrosis of the humeral head has a risk of progression to collapse in absence of treatment. The purpose of this study was to evaluate the results of mesenchymal stem cell grafting of the pre-collapse humeral head (study group) in adult patients with osteonecrosis and to compare the results with a simple core decompression without cells (control group). Patients After inclusion and randomization of 50 patients, 26 patients were enrolled in a single-blinded study for the cell therapy group. Twenty-four other patients were treated with simple core decompression without cells (control group). MATERIAL AND METHODS After a mean of 12-year (range 10 to 15) follow-up, X-ray and MRI were used to evaluate the radiological results, while the Constant score and the visual analog scale were chosen to assess the clinical results. The cell therapy group was treated with percutaneous mesenchymal cell (MSCs) injection obtained from bone marrow concentration. The average total number of MSCs (counted as the number of colony-forming units-fibroblast) injected in each humeral head was a total injection of average 180,000 ± 35,000 cells (range 74,000 to 460,000). RESULTS Both the treatment and control groups had a significantly improved clinical score (p < 0.01). At the last follow-up, pain on the visual analog scale and Constant score in the study group had significant improvement (respectively p < 0.001 and p < 0.01) as compared to the control group. Collapse was observed more frequently in the control group (87.5% versus 11.5% for cell therapy, p < 0.0001). The survival rates based on the requirement for further shoulder surgery (arthroplasty) as an endpoint were higher in the cell therapy group in comparison to those in the control group (92% versus 25%; p < 0.0001). CONCLUSION Core decompression with cell therapy was a safe and effective procedure for treatment in the pre-collapse stages of posttraumatic shoulder osteonecrosis and improved the outcome of the disease as compared with simple core decompression without cells.

Double plating - surgical technique and good clinical results in complex and highly unstable proximal humeral fractures. Injury 2021; 52:2285-2291.

Abstract
INTRODUCTION A stable fixation of highly unstable proximal humerus fractures remains challenging and complication rates, especially secondary varus dislocation, remains high. Different techniques of double plate osteosynthesis have been suggested for the treatment of complex proximal humeral fractures as they are well established for other fractures. The aim of this study was to evaluate an operative technique using an angular stable lateral plate supported by a one-third tubular plate positioned anteriorly at the lesser tuberosity for unstable proximal humeral fractures. PATIENTS AND METHODS Retrospectively, patients treated with a double plate osteosynthesis were included between January 2014 and December 2017. Out of 31, 25 patients (80.6%) with an average age of 53.1 years ± 12.5 were available for follow-up. 60% of the patients were male. The clinical evaluation consisted of a physical examination and standardised questionnaire including subjective and objective shoulder scores like the Constant-Murley Shoulder Score, Simple Shoulder Score, and Subjective Shoulder Value. RESULTS After a mean follow-up of 30.9 months (range, 12-76 months) eighteen patients (72%) had either excellent or good results regarding the Constant-Murley Shoulder Score with a mean value of 77 points ± 17. Average Simple Shoulder Score was 76% ± 0.2 and Subjective Shoulder Value 72% ± 0.2%. Mean NSA at time of follow-up 135° ± 13°. Nine patients had an implant-removal, five in combination with arthrolysis after a mean of 7.2 months. Three patients underwent surgery for secondary arthroplasty. The study shows a complication rate of 16%. No revision-surgery because of secondary varus dislocation was reported. DISCUSSION Arthroplasty is the less favourable treatment for a younger, active cohort of patients with highly unstable proximal humeral fractures as results are not as good and options for revision are limited. Double plate osteosynthesis can be used in addition to calcar screws, bone graft augmentation, cement augmentation and additional free screws for more multidirectional stability and shows good clinical results despite a higher rate of avascular necrosis and high primary stability with comparable complication-rates to single plate osteosynthesis. It seems to be a valid alternative to primary fracture arthroplasty and can prevent secondary varus displacement.

Abstract
Treatments for proximal humerus fractures (PHFs) often fail to achieve anatomical reduction. The purpose of this study was to evaluate the role of positive medial cortical support (PMCS) in the nonanatomical reduction of PHFs.A retrospective analysis was performed of 78 patients with PHFs who underwent surgery from August 2014 to September 2017 and whose treatments did not achieve anatomical reduction. Based on the results of standard AP radiographs of the shoulders 3, 6, and 12 months after surgery, the patients were divided into PMCS or negative medial cortical support (NMCS) groups. The postsurgical change in head-shaft angle (HSA) between the 2 groups was compared. Shoulder joint function and visual analog scale (VAS) scores of the 2 groups were also compared at the same time.Of the 78 patients analyzed, 37 were in the PMCS group and, 41 in the NMCS group. There was no statistically significant difference in any of the characteristics of the 2 groups (P > .05), or in postsurgical HSA. However, the HSA of the 2 groups had become significantly different (P < .05) 3, 6, and 12 months following surgery. The changes in HSA of the 2 groups were different at various time points (P < .05). One year after surgery, the shoulder function score of the PMCS group was significantly better than that of the NMCS group, as was the VAS score (both P < .05).Patients whose surgery for PHF does not achieve anatomical reduction during surgery can undergo PMCS to achieve improved results, postoperatively. NMCS should be avoided as far as possible.

Abstract
OBJECTIVE A meta-analysis and systematic review was performed to compare outcomes of open reduction and internal fixation (ORIF), hemiarthroplasty (HA), and reverse total shoulder arthroplasty (rTSA) for complex proximal humerus fractures. Data sources: MEDLINE, Embase, and Cochrane Library databases were screened. Search terms included reverse total shoulder arthroplasty, open reduction internal fixation, hemiarthroplasty, and proximal humerus fracture. STUDY SELECTION English-language studies published within the past 15 years evaluating outcomes of ORIF, rTSA, or HA for complex proximal humerus fractures with minimum of 1-year follow-up were included, resulting in 51 studies with 3064 total patients. Review articles, basic science studies, biomechanical studies, and cadaveric studies were excluded. DATA EXTRACTION The methodological quality of evidence was assessed using the Jadad scale and methodological index for nonrandomized studies. DATA SYNTHESIS Demographic data were compared using the χ2 test. Mean data were weighted by study size and used to calculate composite mean values and confidence intervals. Continuous data were compared using the Metan module with fixed effects. Count data were compared using the Kruskal-Wallis test. Alpha was set at 0.05 for all tests. CONCLUSIONS Patients undergoing rTSA had lower risks of complication (relative risk 0.41) and reoperation (relative risk 0.28) than HA patients. rTSA resulted in higher Constant scores (standard mean difference 0.63) and improved active forward flexion when compared with HA (standard mean difference 0.76). Pooled mean data demonstrated better outcome scores and active forward flexion of ORIF versus HA and rTSA, although the patients were younger and had more simple fracture patterns. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Objective To investigate the outcomes of humeral head replacement in the treatment of patients with comminuted proximal humeral fracture. Methods Between February 2013 and September 2016, 56 patients underwent humeral head replacement in our hospital. Of them, 18 cases were diagnosed as comminuted proximal humeral fracture before the operation. The mean age of the patients was 69.5 years old (ranging from 61 to 79 years old). Of them, there were six males and 12 females. All the patients in this group had fresh fractures. They were all treated by artificial humeral head replacements. After the prosthesis was fixed by bone cement reliably, the greater or lesser trochanter and prosthesis handle were sutured and fixed firmly. The interval time from injury to operation ranged from 1 to 5 days. The Constant Functional Score, operation time, blood loss, nerve injury, joint dislocation rate, and infection rate were recorded at the final follow‐up. The clinical data of these patients were retrospectively studied. All of the data were recorded in average form. Results In this study, the mean duration of follow‐up was 4 years, ranging from 3 to 6 years. The operation time ranged from 75 to 120 min, with the average of 82 min. The blood loss ranged from 100 to 400 mL, with the average of 210 mL. The mean score of Constant Functional Score was 83.5 ± 3.1. Of them, 14 cases achieved excellent and good (scores of more than 80), and four cases achieved moderate and poor (scores of less than 80). No patient suffered from joint dislocation, unstable joint, or infection after the operation. There were two patients with axillary nerve injury before the operation. However, the function could be recovered within 3–6 weeks after the surgery. Conclusion The artificial humeral head replacement could be applied for the treatment of patients with comminuted proximal humeral fracture. During the surgery process, the stable structure of shoulder joint could be completely restructured, and the rehabilitation plan should be adjusted reasonably and timely after the operation.

Abstract
Fractures of the anatomical neck of the humerus are an extremely rare pathological entity in the field of orthopedic surgery. One of the most feared complications associated with anatomical neck fracture of the humerus is avascular necrosis (AVN). The literature does not contain clear, evidence-based guidelines for the surgical management. This case report highlights the case of a 33-year-old male patient who presented with anatomical neck humerus fracture dislocation after a snowboarding accident. Computed tomography showed a comminuted displaced fracture involving the right humeral neck associated with anterior dislocation of the right shoulder. A small bony fragment adjacent to the glenoid posteriorly was also revealed. The patient was treated with open reduction and internal fixation (ORIF). After 3 years of follow-up, the patient is fully recovered with a normal range of motion of his right shoulder joint. The patient did not show any signs of AVN of the humeral head throughout the course of the 3-year follow-up. Anatomical neck fractures of the humerus are uncommon injuries in the literature. Due to the poor vascularization and the absence of attachment to soft tissue, there is a significantly high risk of AVN associated with fractures of the anatomical neck of the humerus. The patient presented in our report was treated with ORIF since it allows preservation of the humeral head.

Abstract
Background Proximal humeral fracture-dislocations (PHFD) are a special entity in proximal humeral fracture treatment. The aim of this study is to present our minimally invasive plate osteosynthesis (MIPO) technique through an anterolateral deltoid split approach. In addition, we performed a retrospective cohort study analyzing the patient reported functional outcome and complications. Methods A single center cohort study was performed. All patients operated through a deltoid split approach for PHFD between 2009 and 2016 were eligible for inclusion. The primary endpoint was subjective shoulder function measured with QuickDASH and subjective shoulder value (SSV). Secondary endpoints were complications and implant-related irritation. Results 28 patients were included. The mean age was 49 (SD ± 10.3). The mean follow-up was 48 months (SD ± 23.7). The mean QuickDASH score was 6.8 (SD ±7.8) and the mean SSV was 86 (SD ±14.6). Four patients had a conversion into a reversed arthroplasty (14%), one patient (4%) a shortening of secondary perforated screws, four patients an early re-osteosynthesis (14%), four patients (14%) developed an AVN and in one patient damage of the axillary nerve was observed. 21 patients (75%) had their implant removed. Conclusion Patient reported functional results after humeral head preservation and internal fixation of PHFDs through an anterolateral deltoid spilt approach are promising. However, there is a high rate of re-operations either because of complications or for implant removal. Comparing our data to literature these rates are not depending on the approach chosen.

Abstract
PURPOSE Valgus impacted proximal humeral fractures with substantial displacement may severely compromise shoulder function and open reduction can therefore be considered. Internal fixation hardware may eventually however constitute problems. In a small subset of these fractures, in which there is no medial comminution and intact blood supply it is possible to use a least possible fixation method with solely sutures through the tendons of the rotator cuff and the shaft as described by Bigliani 1990. The aim of the present study was to investigate the outcome of this fixation method in a retrospective series of patients. METHODS Twenty-seven patients, 23 women and 4 men, with a mean age of 66 years (53-83) and minimum follow-up time of 2 years (2-11 years) accepted follow-up with standard shoulder radiographs and 22 were examined with Oxford Shoulder Score (OSS), Constant-Murley (CM) shoulder score and Numeric Rating Scale for pain (NRS). Reoperations or adverse events were recorded. RESULTS The median OSS was 45 (range 5-48) and CM 63 (range 21-98). The relative CM score was 81% of the uninjured side and median NRS 0 (range 0-5). No reoperations were undertaken. One patient had a complete avascular necrosis (AVN), 3 patients had a partial AVN of the humeral head and two a partial resorption of the greater tuberosity. CONCLUSION The use of sutures only for fixation of displaced valgus-impacted proximal humeral fractures provided a relatively reliable outcome with good functional scores and no reoperations. There appears to be no need for the use of hardware for fixation of this rare subset of fractures.

Abstract
The humeral head is the second most common site for nontraumatic osteonecrosis after the femoral head, yet it has attracted relatively little attention. Osteonecrosis is associated with many conditions, such as traumatism, corticosteroid use, sickle cell disease, alcoholism, dysbarism (or caisson disease), and Gaucher's disease. The diagnosis is clinical and radiographic with MRI, with radiographs being the basis for staging. Many theories have been proposed to decipher the mechanism behind the development of osteonecrosis, but none have been proven. Because osteonecrosis may affect patients with a variety of risk factors, it is important that caregivers have a heightened index of suspicion. Early detection may affect prognosis because prognosis is dependent on the stage and location of the disease. In particular, the disease should be suspected in patients with a history of fractures, steroid usage, or sickle cell disease, and in divers. This report reviews osteonecrosis of the humeral head, with an emphasis on causes, clinical evaluation, imaging, and classification.

Abstract
BACKGROUND One of the main shortcomings of current proximal humeral plate designs is their inability to reliably secure the greater tuberosity (GT) or lesser tuberosity, leading to fixation failure, nonunion, and rotator cuff dysfunction. Traditional proximal humeral locking plates (PHLPs) rely on isolated screw fixation or suture repair to maintain reduction of the greater and/or lesser tuberosities. This study evaluates a tuberosity-based plate (TBP) specifically designed to improve tuberosity fixation, which may decrease tuberosity displacement and related clinical sequelae. METHODS Five cadaveric specimens (10 shoulders) were randomized to receive either standard PHLP or TBP fixation. The specimens were skeletonized except for the rotator cuff insertion on the GT. A reproducible 3-part osteotomy was performed for each cadaver, creating head, shaft, and GT segments. Anatomic reduction and plate fixation were performed according to the surgical technique guide for each plate system, with an equal number of screws placed in each plate both proximally and distally. GT fixation was enhanced with standardized suture augmentation through the rotator cuff in every specimen in both groups. In each trial, fracture displacement, load to failure, number of cycles endured, and mechanism of failure were noted. RESULTS The mean load to tuberosity fixation failure for the PHLP and TBP groups was 220 and 502 N (P = 0.005), respectively. CONCLUSIONS The TBP had a significantly higher load to failure and significantly lower mean fracture displacement compared with the PHLP.

Abstract
CASE The expandable intramedullary cage (Conventus Orthopaedics) may treat 3- and 4-part proximal humerus fractures. Cage removal for symptomatic avascular necrosis with humeral head collapse requiring conversion to arthroplasty can be challenging because the cage's collapsing mechanism becomes inoperable after fracture consolidation. We present cage explantation followed by reverse total shoulder prosthesis placement in a 54-year-old man who underwent plate/cage fixation for a 3-part proximal humerus fracture 10 months earlier. CONCLUSION The proximal humeral cage can be extracted safely while preserving adequate bone stock for subsequent arthroplasty. Additional time and exposure are necessary compared with removing a locking plate alone.

Abstract
BACKGROUND Screw-tip augmentation in angular stable plating offers new possibilities for the treatment of complex proximal humerus fractures. This retrospective analysis was performed to evaluate the radiological outcome of proximal humerus fractures treated with angular stable plates and additional screw-tip cement augmentation in patients over the age of 60. MATERIALS AND METHODS A retrospective single centre analysis was conducted from June 2013 to December 2016. The minimum follow-up time was set to 6 months after surgery. Anatomical reduction and fixation were evaluated in respect to reattached tuberosities to the head fragment and the adequate restoration of the calcar area not showing any valgus or varus malalignment. Complete fracture healing was determined 3 months after surgery. Any failures such as secondary displacement, primary screw perforation, intraarticular cement leakage and avascular necrosis of the humeral head with concomitant screw cut-out were assessed. RESULTS In total, 24 patients (21 females; 3 males) at a median age of 77.5 (62-96) years were included. Five 2-part, twelve 3-part and seven 4-part fractures were detected. The measured median BMD value of 23 patients was 78.4 mg/cm3 (38.8-136.9 mg/cm3). Anatomical reduction was achieved in 50% of the patients. In most cases, the A level screws and the B1 screw were augmented with bone cement by a median of 7 (5-9) head screws used. Postoperative varus displacement was not detected in any of the patients. One patient (4.2%) sustained an early secondary displacement. Intraarticular cement leakage was detected in 3 patients (2 head-split fractures). Avascular necrosis of the humeral head was observed in 4 patients (16.7%). Revision surgery was necessary in four cases, using hemiarthroplasty twice and reverse shoulder arthroplasty the other two times. CONCLUSION Screw-tip augmentation in angular stable plating for proximal humerus fracture treatment showed a low secondary displacement rate of 4.2% in patients suffering from poor bone quality. Nevertheless, the occurrence of avascular necrosis of the humeral head with mainly severe fracture patterns observed in this study was higher compared to previously reported results in the literature. Cement augmentation in head-split fractures is not recommended, considering the high risk of an intraarticular cement leakage.

Abstract
BACKGROUND Intramedullary nailing is already established technique for the treatment of two and three-part fractures of proximal humerus. The aim of the study was to prospectively evaluate the efficacy and functional outcome after treatment of four-part fractures of proximal humerus with Multiloc proximal humeral nail. DESIGN prospective monocentric cohort study. SETTING single level 1 traumacenter. MATERIALS AND METHODS From February 2011 to March 2016, 40 patients with displaced four-part proximal humeral fractures were treated with intramedullary nail inserted through anterolateral approach. Minimum one year follow up completed 35 patients and were involved into the study. RESULTS After mean follow up period of 25.8 months 29 of 35 fractures healed. Average absolute Constant score in all 35 patients reached 57.7 points, relative side related Constants score 66.8% of contralateral extremity. Together there were 20 complications. in 6 cases (17%) developed complete avascular necrosis of the head. One deep infection was treated by implantation of antibiotic cement discs. Twelve secondary surgeries were performed, mostly for avascular necrosis development. Function and pain were significantly influenced by the quality of fracture reduction (p < 0.05) and development of complete AVN (p = 0.001). Group of 29 patients without AVN reached relative Constant score 73% of contralateral extremity. CONCLUSIONS Intramedullary nailing can be used as possible fixation technique for the treatment of four-part fractures of proximal humerus. In experienced hands provides nailing osteosynthesis similar results as reconstruction with locking plates. Appropriate reduction of fracture fragments is the key for good functional result. LEVEL OF EVIDENCE Level 2b - monocentric prospective cohort study.

Abstract
Posttraumatic avascular necrosis (AVN) is osteonecrosis from vascular disruption, commonly encountered after fractures of the femoral neck, proximal humerus, talar neck, and scaphoid. These locations have a tenuous vascular supply; the diagnosis, risk factors, natural history, and treatment are reviewed. Fracture nonunion only correlates with AVN in the scaphoid. In the femoral head, the risk is increased for displaced fractures, but the time to surgery and open versus closed treatment do not seem to influence the risk. Patients with collapse are frequently symptomatic, and total hip arthroplasty is the most reliable treatment. In the humeral head, certain fracture patterns correlate with avascularity at the time of injury, but most do not go on to develop AVN due to head revascularization. Additionally, newer surgical approaches and improved construct stability appear to lessen the risk of AVN. The likelihood of AVN of the talar body rises with increased severity of talar injury. The development of AVN corresponds with a worse prognosis and increases the likelihood of secondary procedures. In proximal pole scaphoid fractures, delays in diagnosis and treatment elevate the risk of AVN, which is often seen in cases of nonunion. The need for vascularized versus nonvascularized bone grafting when repairing scaphoid nonunions with AVN remains unclear.

Abstract
BACKGROUND We describe a minimally open reduction and percutaneous fixation technique for three- and four-part proximal humeral fracture-dislocations which preserves soft tissues. METHODS Eleven consecutive patients with three-and four-part proximal humeral fracture-dislocations (eight anterior, three posterior dislocations) were treated this way. The dislocation is reduced using a mini-open deltopectoral approach with a horizontal split in subscapularis. Fracture fragments are fixed with percutaneous screws. Constant and Oxford Shoulder Score were collected prospectively. RESULTS Mean age was 51 years (range 32-65). Mean follow-up was 36 months (range 24-72 months). At last follow-up mean Constant score was 75 (range 64-86) compared to 88 (range 85-92) for the uninjured shoulder. Mean Oxford shoulder score was 41 (range 34-46). One patient developed avascular necrosis. Screw back out was seen in three patients. These were removed under local anaesthesia. There were no screw penetrations of articular surface. One patient suffered a radial nerve neuropraxia which resolved. CONCLUSION These results are promising and comparable to published literature with other means of fixation for this complex problem. Due to minimal soft tissue dissection the complications rate is low.

Abstract
BACKGROUND This study compared the clinical and radiologic outcomes of screw tip-augmented locking plate osteosynthesis vs. standard locked plating in elderly patients with displaced proximal humeral fractures. METHODS Of the 94 patients older than 65 years with displaced proximal humeral fractures, 55 underwent fixation with a locking plate only whereas 39 underwent fixation using a locking plate with fluoroscopy-controlled polymethyl methacrylate augmentation of screw tips. RESULTS At 2 years' follow-up, the locking plate-only group showed a mean Constant score (CS) of 62.6 ± 17.4 points, mean CS as a percentage of the uninjured side of 78.2% ± 18.9%, and mean age- and sex-adjusted CS of 72.4 ± 20.5 points. Among the 39 patients who underwent locked plating with polymethyl methacrylate augmentation of screw tips, the mean CS was 63.7 ± 18.5 points (P = .28), the mean CS as a percentage of the uninjured side was 79.5% ± 20.4% (P = .36), and the mean age- and sex-adjusted CS was 76.8 ± 26.2 points (P = .11). The mean Disabilities of the Arm, Shoulder and Hand score was 26.4 ± 21.3 in the locking plate-only group compared with 23.6 ± 19.2 in the group with screw tip-augmented locking plate osteosynthesis (P = .41). The overall complication rate was 16.3% in the locking plate-only group compared with 12.8% in the group with screw tip-augmented osteosynthesis (P = .86); loss of fixation occurred in 10.9% vs. 5.1% (P = .74). The follow-up rate was 81%. CONCLUSIONS Loss of fixation was less frequent when augmentation of screw tips was performed; however, at the 2-year follow-up, the clinical and radiologic outcomes were not significantly different compared with standard locked plating without augmentation.

Abstract
Background It is known that there are large regional variations in treatment methods for the management of proximal humeral fractures. The objective of this study was to investigate the national surgical trends in elderly patients with proximal humeral fractures in South Korea. Methods We analyzed the Korean Health Insurance Review and Assessment Service database from 2008 to 2016. International Classification of Diseases, 10th revision codes and procedure codes were used to identify patients aged ≥65 years with proximal humeral fractures. Results A total of 69,120 proximal humeral fractures were identified from 2008 to 2016. The overall operative rate for proximal humeral fractures increased steadily from 24.6% in 2008 to 36.8% in 2016 (p < 0.001). The rate of cases treated with open reduction and internal fixation tended to increase each year, from 71.5% of the overall surgeries in 2008 to 85.6% in 2016; conversely, the rate of cases treated with closed reduction and internal fixation tended to decrease from 19.9% in 2008 to 4.5% in 2016. In terms of type of arthroplasty procedure, the rate of cases treated with reverse shoulder arthroplasty tended to increase significantly each year, from 8.2% of the overall arthroplasty procedures in 2008 to 52.0% in 2016 (p < 0.001). The proportion of reverse shoulder arthroplasty was shown to increase especially in patients aged 80 years or older. Conclusion Overall, our findings indicated that surgical treatment of proximal humeral fractures, particularly by open reduction and internal fixation, continues to increase; in terms of type of arthroplasty procedure, the rate of cases treated with reverse shoulder arthroplasty tended to increase.

Abstract
INTRODUCTION Minimally invasive plate osteosynthesis (MIPO) has been described as a suitable technique for the treatment of proximal humerus fractures, but long-term functional results have never been reported. The aim of this study was to describe the long-term functional outcome and implant-related irritation after MIPO for proximal humerus fractures. METHODS A long-term prospective cohort analysis was performed on all patients treated for a proximal humerus fracture using MIPO with a Philos plate (Synthes, Switzerland) between December 2007 and October 2010. The primary outcome was the QuickDASH score. Secondary outcome measures were the subjective shoulder value (SSV), implant related irritation and implant removal. RESULTS Seventy-nine out of 97 patients (81%) with a mean age of 59 years were available for follow-up. The mean follow-up was 8.3 years (SD 0.8). The mean QuickDASH score was 5.6 (SD 14). The mean SSV was 92 (SD 11). Forty out of 79 patients (50.6%) had implant removal, and of those, 27/40 (67.5%) were due to implant-related irritation. On average, the implant was removed after 1.2 years (SD 0.5). In bivariate analysis, there was an association between the AO classification and the QuickDASH (p = 0.008). CONCLUSION Treatment of proximal humerus fractures using MIPO with Philos through a deltoid split approach showed promising results. A good function can be assumed due to the excellent scores of patient oriented questionnaires. However, about one-third of the patients will have a second operation for implant removal due to implant-related irritation.

Abstract
Proximal humerus fractures involving an articular head split are rare and complex injuries. In the elderly population, arthroplasty is the optimal treatment, whereas in younger patients, the utility of arthroplasty procedures is limited by concerns of long-term implant survival. As a result, open reduction and internal fixation is still often the first-line treatment option for head-splitting injuries. The traditionally described deltopectoral or anterolateral surgical approaches to the proximal humerus rely on indirect reduction and limited visualization of the articular fragments. We present a case series of younger patients with head-split proximal humerus fractures treated with open reduction and internal fixation through a deltopectoral approach with a subscapularis peel to improve humeral head visualization, reduction, and fixation. The improved reduction may lead to better long-term outcomes and reduce the need for additional surgical procedures. In addition, there were no cases of avascular necrosis in this series.

Abstract
Background Although the proximal humeral fractures (PHFs) treated with locking plate have been well applied, there are few studies concerning on the serial HSA changes after locking plate placement. The purpose of this retrospective study was to explored the clinical significance of serial HSA changes after surgery. Methods We retrospectively analyzed the clinical data of 122 patients between January 2012 to December 2016 in our hospital. The serial change of the HSA and Neer’s score of 122 patients were recorded and analyzed. Then, we evaluated the HSA changes affected functional recovery in conjunction with medial support (MS). Moreover, multivariable linear regression analysis was performed to identify any potential confounding factors that may influence functional recovery. Results Of 146 patients, 122 (50 males and 72 females) patients were finally enrolled in our study. Our preliminary data suggested that the most decrease of HSA occurred in the period of 1 to 3 months (p < 0.001) postoperatively, and functional recovery was significantly related with the change of HSA (R2 = 0.647, p < 0.001). The presence of MS plays an important role in maintaining postoperative HSA and restoring function. Moreover, Neer type 4 fracture, the difference between the postoperative HSA (on the injured side) and that of the uninjured side (the ΔHSA), and the HSA change to the end of follow-up were all significantly associated with functional recovery. Conclusions Serial HSA changes were evident in PHF patients in whom locking plates had been inserted; it is essential to maintain reduction for 1–3 months postoperatively. MS is important in this context and surgeons must maximally restore MS. Furthermore, the functional outcome tended to improve when the HSA of the injured side was restored to a value close to that of the uninjured side.

Abstract
OBJECTIVES To determine the effect of osteonecrosis (ON) on the clinical and functional outcome after open reduction and internal fixation of proximal humerus fractures. DESIGN Prospective cohort study. SETTING Academic medical center. PATIENTS Over a 12-year period, patients were screened and identified on presentation to the emergency department or in the clinical office for inclusion in an institutional review board-approved registry. One hundred sixty-five patients with 166 proximal humerus fractures met inclusion criteria. Eight patients developed radiographic evidence of ON (4.8%). INTERVENTION Surgical repair of proximal humerus fractures. MAIN OUTCOME MEASURE Patients were divided into 2 cohorts; 1 cohort being those diagnosed with ON and the other cohort being those who were not. All patients were prospectively followed and assessed for clinical and functional outcomes at the latest follow-up visit (mean = 22.9 months) using the Disabilities of Arm, Shoulder and Hand survey along with ranges of motion of the injured extremity. RESULTS Average postoperative forward elevation for patients with ON was worse than those without ON (P = 0.002). Additionally, there was a significant difference in Disabilities of Arm, Shoulder and Hand scores at the latest follow-up between the 2 groups (P = 0.026). There was no difference in external rotation or mean length of follow-up between the 2 groups (P > 0.05). CONCLUSIONS This study demonstrates the negative effects of ON after open reduction and internal fixation of proximal humerus fractures. Those who develop ON have poorer functional and clinical outcomes as compared with patients without ON. Consequently, the development of ON can be used as a predictor of poor outcomes. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Is reverse total shoulder arthroplasty more effective than hemiarthroplasty for treating displaced proximal humerus fractures in older adults? A systematic review and meta-analysis. Orthop Traumatol Surg Res 2018; 104:759-766. [PMID: 29969722 DOI: 10.1016/j.otsr.2018.04.025] [Citation(s) in RCA: 61] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2017] [Revised: 03/29/2018] [Accepted: 04/19/2018] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The indications for surgical treatment of displaced proximal humerus fractures in older patients have gradually changed in the past 10 years: fewer hemiarthroplasty (HA) procedures but more reverse shoulder arthroplasty (RSA) procedures are being done. The aim of this study was to determine the clinical and radiological outcomes, the complications, reoperations and revisions of RSA and to compare them with those of HA. MATERIAL AND METHODS A systematic review of the literature published between January 2006 and February 2016 was carried out to identify studies reporting or comparing results of HA and RSA for proximal humerus fractures in patients above 65 years of age. These studies were classified based on their quality and level of evidence. Of the 67 studies that were identified and reviewed, 22 were chosen for the analysis. RESULTS The functional outcome (Constant score) after RSA is significantly better and more reproducible that the one obtained after HA. RSA provides significantly better active range of motion in forward flexion and abduction than HA. Conversely, active internal and external rotation are worse after RSA than HA. Reattachment of the tuberosities around the RSA improves the rotation ability. Even if the tuberosities do not heal, the functional outcomes are satisfactory after RSA but not HA due to a major functional deficit. The tuberosity healing rate around the RSA does not decline with age, contrary to HA where age is a negative factor. The overall complication rate is higher after RSA than HA; however the reoperation rate is equal. The revision rate for implant change is higher after HA. CONCLUSION Compared to HA, RSA provides more reproducible function with better recovery of active forward flexion and abduction, even when the tuberosities are not reattached or do not heal properly. The poor rotation ability can be improved by reinserting the tuberosities. While the complication rate after RSA is higher than after HA, the reoperation rate is equal, and the revision rate is lower. LEVEL OF EVIDENCE IV, Systematic review of literature.

Abstract
BACKGROUND Proximal humerus fractures are the third most common fracture in the elderly population and are expected to increase due to the aging population. Surgical fixation with locking plate technology has increased over the last decade despite a lack of proven superiority in the literature. Three previous randomized controlled trials have not shown a difference in patient-centered outcomes when comparing non-operative treatment with open reduction and internal fixation. Low patient enrollment and other methodological concerns however limit the generalizability of these conclusions and as a result, management of these fractures remains a controversy. By comparing the functional outcomes of locked plate surgical fixation versus non-operative treatment of displaced three and four-part proximal humerus fractures in the elderly population with a large scale, prospective, multi-centered randomized controlled trial, the optimal management strategy for this common injury may be determined. METHODS We will conduct a prospective, single blind randomized controlled parallel arm trial to compare non-operative management of proximal humerus fractures with open reduction and internal fixation using locked plating technology. One-hundred and sixty patients > age 60 with acute 3- or 4- part proximal humerus fractures will be randomized to either open reduction and internal fixation with locked plating technology or non-operative management treatment arms. The primary outcome measure is the Constant Score at 24 months post-operative. Secondary outcome measures include the American Shoulder and Elbow Surgeon's Score (ASES), EuroQol EQ-5D-5 L Health Questionnaire Score, short form PROMIS upper extremity score and IPAQ for the elderly score. Further outcome measures include assessment of the initial classification, displacement and angulation and the quality of surgical reduction via a standard computed tomography (CT) scan; rates of non-union, malunion, arthrosis, osteopenia or other complications including infection, nerve injury, intra-articular screw penetration, reoperation rates and hospital re-admission rates. DISCUSSION The results of this trial will provide Level 1 evidence to guide decision-making in the treatment of proximal humerus fractures in the elderly population.

Rate of avascular necrosis after fracture dislocations of the proximal humerus: Timing of surgery. ACTA ACUST UNITED AC 2018; 13:273-278. [PMID: 30546492 PMCID: PMC6267377 DOI: 10.1007/s11678-018-0452-6] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2017] [Accepted: 02/09/2018] [Indexed: 10/26/2022]
Abstract
Background Avascular necrosis (AVN) of the humeral head is a severe complication after proximal humerus fracture dislocations, and leads to a poorer clinical outcome and subsequent revision surgeries. The aim of the current study was to analyze the influence of time to surgery on the AVN rate after locked plating of dislocation fractures of the proximal humerus. Patients and methods This retrospective study included 30 patients with a mean age of 63 ± 14 years with dislocation fractures of the proximal humerus type B3 or C3 according the AO/OTA classification. The rates of AVN of the humeral head were determined clinically and radiographically. In addition, the clinical outcome was determined using the Constant score (CS), the age- and sex-adjusted Constant score (CS%), Disabilities of the Arm, Shoulder, and Hand (DASH) score, the range of motion, and complication and revision rates. Patients were subdivided into groups of subjects operated on early (≤48 h after trauma) and those with late surgery (>48 h after trauma), and the relative risk (RR) for complications and revisions was determined for both groups. Results After a mean follow-up of 37 months (range: 12-66 month) the mean CS% was 60 ± 24 and the mean DASH score was 32 ± 24 points. Ten patients (33%) developed a symptomatic AVN, and ten patients underwent revision surgery. Early surgery was performed on 25 patients while five patients underwent late surgery. After late surgery, all five patients developed AVN, and patients had a fivefold increased RR for AVN (p = 0.002) and subsequent associated surgical revision (RR = 3.3, p = 0.031). Conclusion In fracture dislocations of the proximal humerus, early surgery within 48 h of trauma significantly decreases the risk of AVN and subsequent surgery.

Abstract
Background Cement augmentation (CA) of humeral head screws in locked plating of proximal humeral fractures (PHF) was found to be biomechanically beneficial. However, clinical outcomes of this treatment have not been well evaluated to date. Objectives To assess outcomes of locked plating of PHF with additional CA and to compare them with outcomes of conventional locked plating without CA. Methods 24 patients (mean age, 74.2 ± 10.1 years; 22 female) with displaced PHF were prospectively enrolled and treated with locked plating and additional CA. The Constant score (CS), the Simple Shoulder Test (SST), and the Simple Shoulder Value (SSV) were assessed 3 and 12 months postoperatively. Fracture healing and potential complications were evaluated on postoperative radiographs. The CS and complications were compared with the outcomes of a matched group of 24 patients (mean age, 73.9 ± 9.4 years; 22 female) with locked plating of displaced PHF without CA. Results At the 3‑month follow-up, the mean CS was 59.9 ± 15.6 points, the mean SST was 7.5 ± 2.7 points, and the mean SSV was 63.9 ± 21.7%. All scores significantly improved by the 12-month follow-up (p < 0.05; CS, 72.9 ± 17.7; SST, 9.2 ± 3.2; SSV, 77.2 ± 17.3%). There were two cases (8%) of biological complications (n = 1 varus malunion and n = 1 humeral head necrosis). Compared with locked plating without CA, no significant differences were observed between the CS at the 3‑ (57.8 ± 13.4 points; p = 0.62) and 12-month (73.0 ± 12.8 points; p = 0.99) follow-up. However, patients without CA had a significantly increased risk of early loss of reduction and articular screw perforation (p = 0.037). Conclusion Locked plating of proximal humeral fractures with trauma cement augmentation of humeral head screws could be translated from the ex-vivo lab setting into the clinical situation without additional complications. Locked plating of displaced PHF with additional cement augmentation showed similar clinical outcomes but reduced the rate of early implant-related complications compared to locked plating without additional CA.

Detection of primary screw perforation in locking plate osteosynthesis of proximal humerus fracture by intra-operative 3D fluoroscopy. Arch Orthop Trauma Surg 2017; 137:1491-1498.

Abstract
PURPOSE The purpose of this study was to identify the rate of primary screw perforations after osteosynthesis of proximal humerus fractures with intra-operative 3D fluoroscopy and to analyse the rate of secondary screw perforations as well as complications, outcome, and revision surgeries after a minimum of 12 months. MATERIALS AND METHODS Thirty-three patients (20 female, 13 male, median age 67 years, range 35-85 years) with displaced proximal humerus fractures were included. After reduction and fixation, an intra-operative 3D fluoroscopy was performed to evaluate primary screw perforations (PS) and screws with "near perforation" (nPS). These screws were changed intra-operatively. Patients were followed-up for a minimum of 12 months. Clinical and radiological parameters, such as secondary screw perforation, secondary loss of reduction, or functional outcome, were investigated. RESULTS In six patients (18.2%), humeral head screws were changed due to primary PS (n = 2) or nPS (n = 4) after the intra-operative 3D fluoroscopy. Follow-up revealed an adapted constant score (%CMS) of 76.2% after a mean follow-up of 17.7 months. Two secondary screw perforations were observed (6%). Loss of reduction was observed in eight patients (24.2%). CONCLUSION The intra-operative 3D reveals a high rate of primary screw perforations or near perforations. Immediate change of these screws may lead to a lower rate of secondary screw perforations and, therefore, reduce post-operative complications.

Abstract
PURPOSE Avascular necrosis (AVN) of the humeral head is a devastating complication of proximal humeral fracture (PHF) that often results in long-term morbidity for the patient. Rates of AVN depend on the number of fracture fragments and are highly variable. The literature suggests that timely stable and anatomic reduction may decrease the rate at which AVN develops after PHF. To our knowledge, there is no literature published investigating a temporal relationship between the timing of PHF fixation and rates of AVN. METHODS Operative records of one orthopedic trauma surgeon were used to identify patients that underwent open reduction internal fixation for PHF at our institution between 2007 and 2012. Radiographs at presentation were reviewed and used to classify the fractures into two, three or four parts. Date and time of the initial radiograph were recorded as were the date and time of available intra-operative fluoroscopic images. The time from presentation radiograph to operative fixation was calculated (hours). Available follow-up plain films were then reviewed and evaluated for the presence or absence of humeral head AVN. RESULTS Time to surgery (less than or greater than 72 h) and patient age did not correlate with development of AVN after PHF (p > 0.26). Notably, the number of fracture fragments did influence the rate of AVN identified in patients with PHF (p = 0.002). CONCLUSION Early operative intervention does not appear to decrease the rate of development of avascular necrosis after PHF.

Abstract
INTRODUCTION Humeral head necrosis (HHN) remains a major problem in fracture care. Neither its occurrence, its extend, nor its impact on clinical outcomes is predictable on the long term. This study was designed to evaluate clinical and radiological outcomes in patients depending on the influence of HHN. PATIENTS AND METHODS 32 patients with a 3-6 year follow up participated in this study. Their humeral fractures had been stabilized with a standard Targon PH nail (Aesculap, Tuttlingen, Germany) for an acute humeral head fracture. Constant score (CS), DASH score, UCLA shoulder rating scale, and Neer score were assessed. Range of motion (ROM) as well as pain during exercise was documented (VAS). HHN was detected radiologically and graded in stages 0-5. RESULTS All fractures had healed. HHN was found in 10 cases (31.3%). 4 patients (12.5%) showed interlocking screw perforation as part of the head collapse caused by HHN. Median CS was 73 (range: 24-85). There was no association detectable between number of fracture fragments and CS (p ≥ 0.631). The median DASH score was 16.4 (range: 0-74.1), UCLA score 30 (range: 9-35), Neer score 80 (range: 29-100). Three (37.5%) of the patients with a stage IV or V osteonecrosis reported about pain (twice VAS grade 4, once VAS grade 5). All patients suffering from pain were affected by high grade HHN and screw perforation. CS was nonsignificantly affected by HHN (75.5 vs. 63.5; p = 0.12), however massively diminished if additional implant protrusion was present (63.5 vs. 25; p = 0.02). Findings for normalised CS, relative CS, DASH score, UCLA shoulder rating scale, Neer score, and ROM were analogous. DISCUSSION Whereas HHN itself seems to contribute only mildly to functional outcome, we identified screw protrusion as major predictor for bad clinical results. The high rate of HHN found in our study (31.3%) may be attributed to the inclusion of mild HHN and our long follow-up period, as it is known that late-onset HHN may occur more than 3 years after trauma. CONCLUSIONS HHN may lead to screw perforation, resulting in poorest outcomes. We recommend regular clinical and radiographic follow-up for at least five years in order to detect impending screw perforation and plan screw removal in time.
