Front Bioeng Biotechnol 2024; 12:1425643. [PMID: 39040497 PMCID: PMC11260706 DOI: 10.3389/fbioe.2024.1425643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Accepted: 06/19/2024] [Indexed: 07/24/2024] Open
Abstract
Proximal humerus fractures (PHFs) are common in the elderly and usually involve defects in the medial column.The current standard for medial column reconstruction is a lateral locking plate (LLP) in combination with either an intramedullary fibula support or an autogenous fibula graft. However, autogenous fibula graft can lead to additional trauma for patients and allogeneic fibular graft can increase patients' economic burden and pose risks of infection and disease transmission. The primary objective of this study was to introduce and assess a novel "Sandwich" fixation technique and compare its biomechanical properties to the traditional fixation methods for PHFs. In this study, we established finite element models of two different internal fixation methods: LLP-intramedullary reconstruction plate with bone cement (LLP-IRPBC) and LLP-intramedullary fibula segment (LLP-IFS). The biomechanical properties of the two fixation methods were evaluated by applying axial, adduction, abduction, torsional loads and screw extraction tests to the models. These FEA results were subsequently validated through a series of biomechanical experiments. Under various loading conditions such as axial, adduction, abduction, and rotation, the LLP-IRPBC group consistently demonstrated higher structural stiffness and less displacement compared to the LLP-IFS group, regardless of whether the bone was in a normal (Nor) or osteoporotic (Ost) state. Under axial, abduction and torsional loads, the maximum stress on LLPs of LLP-IRPBC group was lower than that of LLP-IFS group, while under adduction load, the maximum stress on LLPs of LLP-IRPBC group was higher than that of LLP-IFS group under Ost condition, and almost the same under Nor condition. The screw-pulling force in the LLP-IRPBC group was 1.85 times greater than that of the LLP-IFS group in Nor conditions and 1.36 times greater in Ost conditions. Importantly, the results of the biomechanical experiments closely mirrored those obtained through FEA, confirming the accuracy and reliability of FEA. The novel "Sandwich" fixation technique appears to offer stable medial support and rotational stability while significantly enhancing the strength of the fixation screws. This innovative approach represents a promising strategy for clinical treatment of PHFs.

Comparative analysis of proximal humerus fracture management in elderly patients: complications of open reduction and internal fixation by shoulder surgeons and non-shoulder surgeons-a retrospective study. Clin Shoulder Elb 2024; 27:32-38. [PMID: 38268320 PMCID: PMC10938022 DOI: 10.5397/cise.2023.00626] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2023] [Revised: 09/12/2023] [Accepted: 09/24/2023] [Indexed: 01/26/2024] Open
Abstract
BACKGROUND Open reduction and internal fixation (ORIF) with a locking plate is a popular surgical treatment for proximal humeral fractures (PHF). This study aimed to assess the occurrence of complications in elderly patients with PHF treated surgically using ORIF with a locking plate and to investigate the potential differences between patients treated by shoulder surgeons and non-shoulder surgeons. METHODS A retrospective study was conducted using a single-center database to identify patients aged ≥70 years who underwent ORIF for PHF between January 1, 2011, and December 31, 2021. Data on the Neer classification, follow-up, occurrence of avascular necrosis of the humeral head, implant failure, and revision surgery were also collected. Statistical analyses were performed to calculate the overall frequency of complications according to the Neer classification. RESULTS The rates of implant failure, avascular osteonecrosis, and revision surgery were 15.7%, 4.8%, and 15.7%, respectively. Complications were more common in patients with Neer three- and four-part fractures. Although the difference between surgeries performed by shoulder surgeons and non-shoulder surgeons did not reach statistical significance, the rate of complications and the need for revision surgery were nearly two-fold higher in the latter group. CONCLUSIONS PHF are highly prevalent in the elderly population. However, the ORIF surgical approach, as demonstrated in this study, is associated with a considerable rate of complications. Surgeries performed by non-shoulder surgeons had a higher rate of complications and a more frequent need for revision surgery. Future studies comparing surgical treatments and their respective complication rates are crucial to determine the optimal therapeutic options. Level of evidence: III.

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.

Abstract
PURPOSE OF REVIEW Proximal humerus fracture dislocations typically result from high-energy mechanisms and carry specific risks, technical challenges, and management considerations. It is vital for treating surgeons to understand the various indications, procedures, and complications involved with their treatment. RECENT FINDINGS While these injuries are relatively rare in comparison with other categories of proximal humerus fractures, fracture dislocations of the proximal humerus require treating surgeons to consider patient age, activity level, injury pattern, and occasionally intra-operative findings to select the ideal treatment strategy for each injury. Proximal humerus fracture dislocations are complex injuries that require special considerations. This review summarizes recent literature regarding the evaluation and management of these injuries as well as the indications and surgical techniques for each treatment strategy. Thorough pre-operative patient evaluation and shared decision-making should be employed in all cases. While nonoperative management is uncommonly considered, open reduction and internal fixation (ORIF), hemiarthroplasty, and reverse total shoulder replacement are at the surgeon's disposal, each with their own indications and complication profile.

Abstract
Background Locked fracture-dislocation of the proximal humerus (LFDPH) is a very severe complex injury; neither arthroplasty nor internal plating are fully satisfactory. This study aimed to evaluate different surgical treatments for LFDPH to determine the optimal option for patients of different ages. Methods From October 2012 to August 2020, patients who underwent open reduction and internal fixation (ORIF) or shoulder hemiarthroplasty (HSA) for LFDPH were retrospectively reviewed. At follow-up, radiologic evaluation was performed to evaluate bony union, joint congruence, screw cut-out, avascular necrosis of the humeral head, implant failure, impingement, heterotopic ossification, and tubercular displacement or resorption. Clinical evaluation comprised the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and Constant-Murley and visual analog scale (VAS) scores. Additionally, intraoperative and postoperative complications were assessed. Results Seventy patients (47 women and 23 men) with final evaluation results qualified for inclusion. Patients were divided into three groups: group A: patients aged under 60 years who underwent ORIF; group B: patients aged ≥60 years who underwent ORIF; and group C: patients who underwent HSA. At a mean follow-up of 42.6 ± 26.2 months, function indicators, namely shoulder flexion, and Constant-Murley and DASH scores, in group A were significantly better than those in groups B and C. Function indicators in group B were slightly but not significantly better compared with group C. Regarding operative time and VAS scores, there were no significant differences between the three groups. Complications occurred in 25%, 30.6%, and 10% of the patients in groups A, B, and C, respectively. Conclusions ORIF and HSA for LFDPH provided acceptable but not excellent results. For patients aged <60 years, ORIF might be optimal, whereas, for patients aged ≥60 years, both ORIF and HSA provided similar results. However, ORIF was associated with a higher rate of complications.

Abstract
BACKGROUND Open reduction and plate internal fixation (ORIF) is one of the most common treatment methods for proximal humeral fractures. Complications associated with the greater tuberosity (GT) are rarely reported, therefore, the purpose of this study was to analyze the complications associated with the GT and the risk factors after locked-plate internal fixation. METHODS We retrospectively analyzed the medical and radiographic data of patients with proximal humeral fractures involving the GT treated with locking plates between January 2016 and July 2019. We divided all patients into two groups, the anatomic GT healing group and the nonanatomic GT healing group, depending on the radiographic outcomes of the GT. Clinical outcome was assessed by the Constant scoring system. Potential risk factors included preoperative and intraoperative factors. Preoperative factors included sex, age, body mass index, fracture type, fracture-dislocation, proximal humeral bone mineral density, humeral head extension, hinge integrity, comminuted GT, volume and surface area of the main GT fragment, and displacement of the main GT fragment. Intraoperative factors were adequate medial support, residual head-shaft displacement, head-shaft angle and residual GT displacement. Univariate logistic regression and multivariate logistic regression were used to identify risk factors. RESULTS There were 207 patients (130 women and 77 men; mean age, 55 years). GT anatomic healing was observed in 139 (67.1%) patients and nonanatomic healing in 68 (32.9%). Patients with GT nonanatomic healing had significantly inferior Constant scores than those with GT anatomic healing (75.0 ± 13.9 vs. 83.9 ± 11.8, P < 0.001). Patients with high GT malposition had worse Constant scores than patients with low GT malposition (73.3 ± 12.7 vs. 81.1 ± 11.4, P = 0.039). The multivariate logistic model showed that GT fracture characteristics were not risk factors for nonanatomic GT healing, while residual GT displacement was. CONCLUSIONS Nonanatomic healing of the GT is a high-rate complication of proximal humeral fractures, resulting in inferior clinical outcomes, especially for high GT malposition. Fracture characteristics of the GT are not risk factors for GT nonanatomic healing and GT comminution should not be regarded as a contraindication to ORIF for proximal humeral fractures.

Abstract
Background The role of hemiarthroplasty (HA) in the management of proximal humerus fractures (PHFs) and their sequalae has evolved with the development of contemporary internal fixation techniques and the widespread use of the reverse total shoulder arthroplasty. However, HA may still have a role in certain acute PHFs as well as select fracture sequalae. The aim of this investigation was to evaluate the outcomes of HA when used in acute fractures and fracture sequelae. Methods Over a 16-year period (2000 - 2016), 122 primary HA performed for either acute PHFs or fracture sequelae were identified. Of these, 70 (57.4%) HA were performed within 4 weeks of the injury, whereas 52 (42.6%) underwent HA for fracture nonunion, malunion, or avascular necrosis. The minimum follow-up period was 2 years. Outcomes included the visual analog scale for pain, range of motion, American Shoulder and Elbow Surgeons (ASES) score, complications, and reoperations inclusive of revision surgery. Cumulative incidence analysis was used to report implant survivorship with death as a competing risk. Results The mean follow-up time after HA was 4.8 years (range, 2-15 years) with no differences between groups (P = .102). Cohort comparisons demonstrated an older age (67.8 vs. 60.1; P = .004), lower rate of previous procedure (4.3% vs. 51.9%; P < .001), lower bone graft use (28.6% vs. 59.6%; P < .001), and a longer length of stay (5.9 vs. 3.0 days; P < .001) in the acute HA group. Additionally, no differences were observed between the acute and sequalae cohort in pain (2.0 vs. 2.5; P = .523), forward elevation (98° vs. 93°; P = .627), external rotation (30° vs. 23°; P = .215), internal rotation score (4.0 vs. 4.5; P = .589), satisfaction (P = .592), ASES scores (64.4 vs. 57.1; P = .168), complications (27.1% vs. 28.8%; P = .836), or reoperations (11.4% vs. 19.2%; P = .229). When comparing acute fractures and sequalae, the 15-year complication rates were 32.4% and 43.3%, respectively (P = .172), with 15-year reoperation rates of 13.7% and 24%, respectively (P = .098). Conclusions HA, whether performed acutely for a PHF or in a delayed fashion for fracture sequalae, demonstrated no statistically significant differences in outcomes for all examined parameters. HA in this setting may provide reasonable pain relief. However, limited motion, marginal ASES scores, and elevated rates of complications and reoperations can be expected up to 15 years postoperatively.

Abstract
PURPOSE OF REVIEW Avascular necrosis (AVN) and posttraumatic arthritis (PTA) are common complications following both conservative treatment and open reduction and internal fixation (ORIF) of proximal humerus fractures (PHFs). Despite the frequent utilization of ORIF, information regarding these leading causes of failure is limited. This review includes a discussion of incidence, risk factors, and evaluation of AVN and PTA following PHF. The mechanisms of treatment options and associated outcomes are also reviewed. RECENT FINDINGS Recent best available evidence demonstrates significant rates of AVN and PTA following ORIF of PHF. This is particularly true of complex fracture patterns. A thorough workup is required in the setting of failure caused by AVN and PTA. This includes a careful patient history, clinical exam, plain film radiographs, and CT scans. EMG and/or aspiration may also be indicated. Special consideration is given to the examination of the deltoid muscle, neurovascular status, rotator cuff function, and the possibility of infection. Biological supplementation, anatomic total shoulder replacement (aTSA), and fusion are rarely employed in the treatment of AVN and/or PTA. Due to satisfactory patient outcomes, reverse total shoulder replacement (rTSA) has increased in popularity for the elderly population, while hemiarthroplasty (HA) may be appropriate for some young, active patients. With careful patient selection and meticulous surgical technique, AVN and PTA can be mitigated. Careful indications for ORIF may decrease the frequency of these complications. For most patients, rTSA is the optimal treatment option. Given the frequent utilization of ORIF and the higher than acceptable complication and failure rates, AVN and PTA warrant our attention.

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.

Abstract
Proximal humeral fractures (PHF) are the third most common fracture in humans and the incidence is increasing. There are basically three treatment strategies: conservative, joint-preserving reconstructive or joint-replacing procedures. In addition to fracture morphology, patient-specific and surgeon-specific factors are particularly important when deciding on treatment. The experience and training of the surgeon also play a decisive role. In the case of joint-preserving treatment, the risk of osteosynthesis failure and of sequelae of the fracture must always be assessed. If conservative or reconstructive treatment methods are not promising, the joint-replacing procedure is the treatment of choice. The anatomical fracture prosthesis is only indicated, if at all, for young patients with a destroyed humeral head with a preserved rotator cuff and large fragments of the tuberosities. In advanced age, the implantation of a reverse endoprosthesis is increasingly used for dislocated, multifragmentary PHF. In both procedures, the anatomical healing of the tuberosities has a significant impact on the functional outcome.

Abstract
Objective The purpose of this study was to evaluate the best placement of calcar screws in proximal humerus fracture surgeries. Methods This retrospective cohort study included clinical and radiographic outcomes of 98 patients treated with proximal humerus fracture surgeries between January 2017 and June 2020. Demographic data of patients were obtained from medical records. The surgical and radiographic results were also collected: operation time, blood loss, time to surgery, fibular allograft, disruption of medial region hinge, Neer classification, and recovery of medial support. Patients were allocated into two groups: the locking plate group (n = 65) and the intramedullary nail group (n = 33). In this study, we proposed new predictive indicators, named horizontal ratio (HR) and vertical ratio (VR), to quantify the placement of calcar screws in these two groups. A receiver operating characteristic (ROC) analysis was conducted to display the accuracy of these indicators. Shoulder activity, visual scale analog (VAS) score, and Constant score were performed to evaluate postoperative clinical outcomes at 1 year follow‐up. Results In the multivariate logistic regression analysis, only time to surgery and effective medial support were considered statistically significant factors of postoperative complications (p < 0.05). Significant differences were observed between medial support and postoperative complications both in the locking plate group and the intramedullary nail group (p < 0.05). Only the vertical ratio of locking plate (VRLP) was a statistically significant predictor of postoperative complications (p < 0.05). The area under curve was calculated to assess the predictive value of VRLP, which came to 0.84. In addition, a ROC analysis found quantifiable thresholds of the VR was 0.1713 as measures to avoid postoperative complications in the locking plate fixation. Conclusion In locking plate fixation, the incidence of postoperative complications increased significantly when the VR of calcar screws greater than 0.1713, which was beneficial to surgeons to place calcar screws.

Abstract
BACKGROUND Treatment of complex proximal humeral fractures in the elderly is a challenge and reverse shoulder arthroplasty (RTSA) is now an important alternative to open reduction internal fixation (ORIF) with angular stable plate. The purpose of this study is to compare clinical and radiological outcomes of RTSA and ORIF in the elderly. METHODS We retrospectively analyzed patients treated for three- or four-part displaced fractures of the proximal humerus. Range of motion, disabilities of the arm, shoulder and hand (DASH) and Constant scores were recorded. X-ray exam in three projections completed the clinical observation at follow-up. RESULTS Forty-eight patients were enrolled after a mean follow-up of 37 months: 22 RTSA and 26 ORIF. Mean age at trauma was 74 years. Compared with RTSA patients, ORIF patients had significantly higher mean external rotation (28° vs. 14°) and better results in modal internal rotation (hand at D7 vs. hand at L5-S1). No significant differences were seen in DASH and Constant scores. Avascular necrosis and loss of reduction with varus dislocation of the humeral head were the most frequent causes of revision surgery in ORIF (34.6%) while the revision rate of the RTSA was 9.1%. CONCLUSION In this study, both treatments showed good clinical outcomes, but RTSA resulted in lower revision rate than ORIF. Even if external and internal rotation in RTSA patients were worse than ORIF, they did not affect the patient's quality of life. So, the reverse arthroplasty seems to be a more reliable treatment.

PHILOS Synthesis for Proximal Humerus Fractures Has High Complications and Reintervention Rates: A Systematic Review and Meta-Analysis. Life (Basel) 2022; 12:life12020311. [PMID: 35207598 PMCID: PMC8880552 DOI: 10.3390/life12020311] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Revised: 02/16/2022] [Accepted: 02/17/2022] [Indexed: 11/25/2022] Open
Abstract
Purpose: The aim of this study was to quantify the rate of complications and reinterventions in patients treated with PHILOS plate for proximal humerus fractures (PHFs) synthesis. Methods: A comprehensive literature search was performed on the PubMed, Web of Science, Embase, and Cochrane databases up to 7 October 2021. Studies describing medium and long-term complications in PHF synthesis using the PHILOS plate were included. A systematic review and meta-analysis were performed on complications and causes of reinterventions. Assessment of risk of bias and quality of evidence was performed with the Downs and Black’s “Checklist for Measuring Quality”. Results: Seventy-six studies including 4200 patients met the inclusion criteria. The complication rate was 23.8%, and the main cause was screw cut-out (4.1%), followed by avascular necrosis (AVN) (3.1%) and subacromial impingement (1.5%). In patients over 55 years, the complication rate was 29.5%. In the deltopectoral (DP) approach the complication rate was 23.8%, and in the delto-split (DS) it was 17.5%, but no difference between the two approaches was seen when considering the type of fracture. The overall reintervention rate was 10.5% in the overall population and 19.0% in older patients. Conclusions: Proximal humerus synthesis with a PHILOS plate has high complications and reintervention rates. The most frequent complication was screw cut-out, followed by humeral head AVN and subacromial impingement. These results need to be further investigated to better understand both the type of patient and fracture that is more at risk of complications and reintervention and to compare pros and cons of the PHILOS plate with respect to the other solutions to manage PHFs.

Abstract
PURPOSE The incidence of proximal humerus fractures (PHF) is rising and surgical intervention carries risk for fracture nonunion. The purpose was (1) to compare patient demographics of those that developed nonunion and (2) identify patient risk factors that predispose to nonunion following open reduction and internal fixation (ORIF) for PHF. METHODS A retrospective review of the Medicare Claims Database from 2005 to 2014 for patients who underwent primary ORIF for PHFs. Patients who developed nonunion were identified as the study group (n = 1020) and compared to a control group (n = 51,209). Primary endpoints were to compare demographics of the study group and the comparison cohorts and to identify patient-related risk factors associated with nonunion within 6-months following the index procedure. A logistic regression model was constructed to determine the association of comorbid conditions on developing a nonunion. A p value of 0.001 was the significance threshold. RESULTS Patients who developed nonunion were younger, more likely to be male, and had higher Elixhauser-Comorbidity Index scores (7 vs. 5; p < 0.0001) when compared with controls. Iron deficiency anemia (OR: 1.32; p = 0.0001), tobacco use (OR: 1.32; p = 0.0004), rheumatoid arthritis (OR: 1.29; p = 0.0001), depression (OR: 1.28; p = 0.0002), and BMI range from 30-39 kg/m2 (OR: 1.21; p = 0.001) were significant risk factors for nonunion. CONCLUSIONS Certain patient risk factors including tobacco use, iron deficiency anemia, rheumatoid arthritis, depression, and a BMI in the range of 30-39 were associated with nonunion within 6 months of ORIF for PHF. This study may help in the risk stratification of these patients.

Abstract
Background The treatment approach for proximal humeral fractures is determined by various factors, including patient age, sex, dominant arm, fracture pattern, presence of osteoporosis, preexisting arthritis, rotator cuff status, and medical comorbidities. However, there is a lack of consensus in the literature regarding the optimal treatment for displaced proximal humeral fractures. This study aimed to assess and quantify the decision-making process for either conservative or surgical treatment and the choice of surgical method among shoulder surgeons when treating proximal humeral fractures. Methods Forty sets of true anteroposterior view, scapular Y projection view, and three-dimensional computed tomography of proximal humeral fractures were provided to 12 shoulder surgeons along with clinical information. Surveys regarding Neer classification, decisions between conservative and surgical treatments, and chosen methods were conducted twice with an interval of 2 months. The factors affecting the treatment plans were also assessed. Results The inter-rater agreement was fair for Neer classification (kappa=0.395), moderate for the decision between conservative and surgical treatments (kappa=0.528), and substantial for the chosen method of surgical treatment (kappa=0.740). The percentage of agreement was 71.1% for Neer classification, 84.6% for the decision between conservative and surgical treatment, and 96.4% for the chosen method of surgical treatment. The fracture pattern was the most crucial factor in deciding between conservative and surgical treatments, followed by age and physical activity. Conclusions The decision between conservative and surgical treatment for proximal humeral fractures showed good agreement, while the chosen method between osteosynthesis and arthroplasty showed substantial agreement among shoulder surgeons.

Abstract
ABSTRACT Objective: To evaluate and compare the proportions of complications and radiographic findings of osteosynthesis of 2- and 3-part proximal humerus fractures with two methods of treatment: third-generation antegrade nailing and locking plate. Methods: 46 patients with a mean age of 58.9 ± 16.6 years between January 2020 and January 2021 were evaluated. In sixteen cases (34.8%), antegrade nailing was used, and in thirty cases (65, 2%), a locking proximal humerus plate. The method used included the rate of complications with a minimum follow-up of 6 months after surgery and radiographic evaluation. Results: There was no difference between the groups regarding the proportion of complications (nail group 18.8%, plate group 13.3%; p = 0.681). The nail group had less residual varus loss (cervicodiaphyseal angle nail group with 132.1º ± 2.3º, plate group 123.8º ± 10.1º; p < 0.001). In the plate group, women had the lowest value (1.43 ± 0.22) of the deltoid tuberosity index (DTI) compared to men (1.58 ± 0.11) (p = 0.022). Conclusion: Osteosynthesis, with a locking plate and antegrade nailing, did not show differences in the proportion of complications. The nail group had less change in the postoperative cervicodiaphyseal angle, however, there were two serious complications with screw cut-out and varus deviation, requiring surgical reapproach.

Abstract
BACKGROUND Proximal humerus fractures (PHF) are common and lead to post-traumatic humerus head necrosis (HHN) in 3-35% after ORIF with an internal locking plate. Few studies focus on this condition and risk factors remain a discussion topic. Hertel's criteria for initial head ischemia right after fracture (fracture complexity, medial hinge displacement and short metaphyseal head extension) have recently been correlated to HHN, but there is still a clear lack of evidence on the topic. Due to its anatomical similarities to the proximal femur, some authors argue that PHF may as well benefit from early surgery to avoid head necrosis. METHODS In this 10-year retrospective study, we assessed 305 patients from a single center. All cases were treated with a PHILOS plate through a deltopectoral approach. The mean follow-up time was 467 days. The primary endpoint was HHN. RESULTS HHN was diagnosed in 12 patients (4%), 10 of which were diagnosed within the first year and one case 4 years after surgery. A positive correlation (p < 0.04) was found between HHN and fracture type (both in AO and Neer's classification), initial neck-shaft-angle (NSA) and metaphyseal head extension (MHE). Medial hinge displacement (MHD) occurred in all HHN cases. Achieving perfect reduction (< 2 mm dislocation) was relevant to avoiding HHN (p = 0.035). Although HHN developed in 32% of the high risk cases (four-part fractures with a short MHE), it was completely avoided (0%) when perfect reduction was achieved. Time until surgery after admission was neither a protective nor a risk factor for HHN. CONCLUSION We conclude that fracture complexity (four-part and C-fractures) as well as disruption of the medial hinge with a metaphyseal head extension smaller than 8 mm are relevant risk factors for humerus head necrosis. A combination of these criteria generated an high risk pattern with a 32% rate of HHN. Though often difficult to achieve, perfect reduction was a clear protective factor and reduced HHN to 0%. Perfect reduction may be key to inosculation and, therefore, salvage of the humerus head, especially in high risk cases. Surgery timing did not correlate with HHN.

Abstract
Background Early failure of osteosyntheses is common even with use of locking plates. In patients with comminuted fractures and epiphyseal osseous defects, we performed a series of osteosyntheses by locking plate in combination with an allograft bone augmentation. Because of encouraging short-term results in the literature, we assumed that the method could be a potential alternative to a reverse shoulder prosthesis. Material/Methods Twenty-six patients with a dislocated proximal humeral fracture (Neer IV/V/VI) were studied. A lyophilized allogeneic bone graft was used to reinforce the humeral head fragments before locking plate osteosynthesis. The outcomes of fractures were assessed with Disabilities of the Arm, Shoulder and Hand (DASH) and Constant-Murley (Constant) scores, range of motion, a visual analog scale, and with radiological testing. The Constant-Murley scores were the endpoint of our study. Results The Neer classification of the fractures was type IV in 4 patients, type V in 20 patients, and type VI in 2 patients. The mean DASH score was 52.85 (range, 4.17–79.3) and the mean Constant score was 39.26 (range, 17–88). We observed late necrosis of the humeral head in 15 of 24 patients (62.5%), although early radiological follow-up showed that the humeral head had been anatomically reconstructed. Conclusions Long-term follow-up demonstrated inferior functional results, as displayed by poor Constant scores. There was a high incidence of necrosis, in spite of initial anatomical reconstruction. Biointegration of the allogeneic bone graft and revascularization of the humeral head fragments could be impaired in geriatric patients who have gross dislocation. Therefore, augmentation of the humeral head with allogeneic bone grafts cannot be recommended in these patients.

Abstract
Proximal humerus fractures (PHF) are a common orthopedic injury; however, their treatment remains largely controversial with evidence supporting a wide array of treatments. Although many injuries can be treated nonoperatively, there has been much debate about surgical management of PHF. A detailed review of the literature was performed relative to operative management options specifically related to implant choices. Although no definitive answers are available regarding best practice, there is literature to guide operative decision-making and implant selection based on both patient- and surgeon-specific factors.

Radiographic parameter(s) influencing functional outcomes following angular stable plate fixation of proximal humeral fractures. INTERNATIONAL ORTHOPAEDICS 2021; 45:1845-1852. [PMID: 33755774 PMCID: PMC8266775 DOI: 10.1007/s00264-021-04945-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/27/2020] [Accepted: 01/07/2021] [Indexed: 11/01/2022]
Abstract
PURPOSE Radiographic parameters which correlate with poor clinical outcome after proximal humeral fractures could be helpful indicators to answer the question which patients should be followed up closer. Moreover, during surgery, radiographic parameters correlating with unfavourable outcome should be avoided. The primary aim of the study was to compare radiographic measurements between the injured and the contralateral, uninjured shoulder. The secondary aim was to correlate these radiographic parameters with post-operative shoulder function. METHODS Fifty-eight patients (age: 55.6 ± 14.4 years, age at surgery) following angular stable plate fixation of a proximal humeral fracture (2-part fractures according to Neer: 24, 3-part: 25, 4-part: 9) were included in this retrospective cohort study. All patients were followed up at least six years (7.9 ± 1.4 after surgical intervention). During follow-up examination, the Constant score (CS) was assessed, and radiographs of both shoulders were taken. Radiographs were analyzed regarding lateral humeral offset, distance between tuberculum and head apex, head diameter, head height, perpendicular height, perpendicular center, vertical height, and angles between head and humeral shaft (CCD and HSA). These parameters were compared between the injured and uninjured shoulder. The cohort was divided in two groups: patients with a CS category of excellent/good and satisfying/worse. Both groups were tested regarding differences of demographic and radiographic parameters. RESULTS The distance between tuberculum and head apex (2.6 ± 3.4 mm vs. 4.3 ± 2.1 mm; p = 0.0017), the CCD (123.1 ± 12.9° vs. 130.1 ± 7.3°; p = 0.0005), and the HSA (33.1 ± 12.8° vs. 40.1 ± 7.3°; p = 0.0066) were significantly smaller on the treated shoulder compared to the uninjured side. Patients reached a Constant score of 80.2 ± 17.4 (95% CI 75.6-84.8) points. Regarding outcome categories of the Constant score, 46 patients had a good to excellent outcome, and 12 patients had a satisfying or bad outcome. The comparison of these groups revealed that patients with inferior outcome in the long-term follow-up were older, female, had a more complex fracture type (AO classification), smaller lateral humeral offset, smaller head diameter and height, lower perpendicular height, and lower CCD and HSA angles. CONCLUSION If the abovementioned parameters cannot be restored sufficiently during surgery, (reversed) shoulder arthroplasty might be a better solution to reach good post-operative outcome. Moreover, patients presenting these radiographic characteristics in the follow-up, older patients, and patients with a more complex fracture type should be followed up closer to possibly prevent poor shoulder function.

Abstract
Background Up to 20% of proximal humeral fractures need to be treated operatively. However, numerus complications were reported by using fixed angled locking plates. The ALPS Proximal Humerus Plating System is a new design implant with novel design features. The aim of this study was to compare the preliminary clinical outcomes and complications of proximal humeral fractures treated with either ALPS or the proximal humeral internal locking system (PHILOS) in Asian patients in Taiwan. Methods Between January 2016 and December 2018, 66 patients with displaced proximal humeral fractures were analyzed retrospectively, of whom 31 underwent ALPS implant treatment and 35 underwent PHILOS implant treatment. Intraoperative blood loss and operation time, postoperative Constant-Murley Shoulder Outcome (Constant-Murley) score, and complications variables were recorded for the comparison. All cases were regularly followed up for at least 1 year. Results The mean follow-up period was 400.8 days (range, 367–446 days). Union was achieved in 98.5% of patients (65/66). The ALPS group yielded similar radiologic and clinical outcomes to the PHILOS plating group for treating displaced proximal humeral fractures, including operation time, intraoperative blood loss, the Constant-Murley score, and varus malunion (P > 0.05, respectively). However, the incidence of total postoperative complications in the ALPS group was significantly lower than in the PHILOS group (P < 0.05). There was a trend of a lower complication rate of screws/pegs protrusion, avascular necrosis, subacromial impingement, postoperative infection, and reoperation in the ALPS group, although it was not statistically significant (P > 0.05, respectively). Conclusion The ALPS group yielded similar radiologic and clinical outcomes to the PHILOS plating group for displaced proximal humeral fractures, but the ALPS group had a significantly lower total rate of complications. Therefore, ALPS may be a better option for treating proximal humeral fractures. Further larger clinical studies are needed to confirm the findings presented here.

Abstract
Proximal humeral fractures (PHF) are the third most common non-vertebral fragility fractures after hip and distal radius. It still controversial which treatment might be more appropriate, and surgically treated outcomes depends also on an appropriate technique. In order to clarify surgical indications, tips and pitfall a narrative review was conducted. Pinning, external fixation, plating and internal fixators has each one its advantages and disadvantages. During the procedure an appropriate use of the fixation device and handling of the soft tissue might be associated with better outcomes. Calcar comminution, varus angulation, medial dislocation of the shaft, fracture-dislocation are factors that could lead to choose a replacement. Hemiarthroplasty and reverse total shoulder arthroplasty are the most common prosthesis used in PHF. The restoration of humeral length and tuberosities might lead to an improvement in clinical outcomes and prosthesis survivorship.

Abstract
This study focuses on problems of treatment of proximal humeral fractures occurring against the background of osteoporosis. It presents statistics on osteoporosis and lower energy trauma among patients in the Russian Federation and abroad. The high susceptibility to osteoporotic changes in the bone structure of the male population of Russia compared to the global statistics of osteoporosis among men was emphasized. The main classifications used in the clinical practice of orthopedists and traumatologists allow to identify the type of fracture by clinical and anatomical basis and to structure the existing patient management tactics to achieve the most optimal result of treatment and restoration of limb function. There is an analysis of publications representing various methods of fracture treatment, which helps to use the most optimal methods of relevant fractures treatment.

Abstract
PURPOSE There is still disagreement regarding the optimal surgical treatment of three- and four-part fractures of the proximal humerus. The aim of this monocentric, retrospective study was to compare the complication rate of internal fixation with a locking plate versus proximal humeral nailing after a one-year follow-up. METHODS From 2005 to 2016, 292 patients suffered a fracture of the proximal humerus and were treated surgically at our level-I trauma center. According to the inclusion criteria, 50 patients were included in this study: 19 of these (11 three-part fractures and 8 four-part fractures) were treated with a proximal humeral nail (HN) and 31 (12 three-part fractures and 19 four-part fractures) with a locking plate (LP) osteosynthesis. Classification was performed according to the Hertel classification. At a 1-year follow-up, the complication rate of the two treatment methods was compared. RESULTS Twenty patients (40%) suffered at least one complication. Of these, six patients (12%) were treated with a HN and 14 (28%) with a LP (p = 0.39). The most frequent complication was screw perforation (22%), followed by non-union (16%). Humeral head necrosis (10%) occurred only in the LP cohort. One wound infection occurred in a patient treated with a HN. Four-part fractures were treated more frequently with a LP. However, the difference was non-significant in this sample (p = 0.186). CONCLUSIONS The results of our study provide some evidence that in terms of complication rate, both treatment options are comparable for internal fixation of three- and four-part fractures of the proximal humerus. The type of fracture seems to be decisive for the choice of implant.

Abstract
INTRODUCTION To the best of our knowledge, there is no consensus on dose-response between smoking, alcohol drinking, and bone healing. The aim of the present study is to conduct a comprehensive systematic review and dose-response meta-analysis of studies to estimate the influence of smoking and alcohol use on the success of non-pathologic bone fracture healing in adult patients. METHODS A systematic search will be performed using MEDLINE, EMBASE and Cochrane CENTRAL, CINAHL, and AMED databases to identify randomized controlled trials and observational studies which have assessed the effect of smoking or alcohol drinking on fracture healing. Primary outcomes include delayed union or nonunion rate and time to union. Secondary outcomes are common complications which occur during bone healing including malunion and wound infection. Risk of bias will be evaluated using the Quality In Prognosis Studies (QUIPS) tool for quality assessment of each study. Dose-response meta-analysis will be performed between smoking, alcohol drinking, and bone healing. Evaluation of the quality of evidence will be conducted using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. RESULTS The present study will assess the effects of smoking and alcohol drinking on non-pathologic bone fracture healing in adult patients. CONCLUSION We hope that this systematic review and dose-response meta-analysis will provide high quality evidence on dose-response between smoking, alcohol drinking, and bone fracture healing.

Abstract
BACKGROUND To date, there is a lack of consensus regarding surgical treatment recommendations for complex proximal humerus fracture (PHF) patterns, especially between joint preservation and joint replacement techniques. METHODS Between 2012 and 2017, 146 patients (aged 74.1 ± 8.0 years) with complex PHF were treated with locking plates (open reduction-internal fixation [ORIF]) or reverse total shoulder arthroplasty (RTSA). Complications and unplanned revision surgery were recorded in a mid-term follow-up. Potential patient and surgical risk factors for complications were extracted. Univariate and multivariate analyses were conducted. RESULTS Follow-up data were available for 125 patients, 66 (52.8%) of whom were treated with locking plates, and 59 (41.2%) with RTSA. Both groups had comparable Charlson indices. The overall complication rate was 37.8% for ORIF and 22.0% for RTSA, with a revision rate of 12.1% and 5.1%, respectively, as driven primarily by persistent motion deficits. Multivariate analyses demonstrated no significant differences between the 2 procedures (P = .500). However, age was an independent protective factor against overall complications (P = .018). Risk factors for major complications in ORIF included osteoporosis, varus impaction fractures, posteromedial metaphyseal extensions <8 mm, head-shaft displacements >4 mm, and multifragmentary greater tuberosities. For RTSA, higher complication rates were seen in patients with higher Charlson indices, diabetes, or altered (greater) tuberosities. In contrast, Neer's classification system was not predictive in either group. CONCLUSIONS RTSA led to fewer complications than ORIF and thus can be considered a valuable option in complex PHF of the elderly. Paying attention to specific prognostic factors may help to reduce the complication rate.

Abstract
Objective: Anterolateral approaches for proximal humerus osteosynthesis have great advantages because they allow direct exposure of the lateral aspect of the humerus without the muscular retraction seen in the deltopectoral approach. However, much resistance is found among surgeons due to the potential risk of iatrogenic injury to the axillary nerve. To identify the incidence of axillary nerve iatrogenic lesions and evaluate the functional results of proximal humerus osteosynthesis with locking plates using anterolateral approaches. Methods: The literature review followed the PRISMA protocol. Results: A total of 23 articles were selected from 786 patients submitted to anterolateral approaches. Three cases (0.38%) of iatrogenic axillary nerve lesions were confirmed. The results of the functional tests were similar to those of the deltopectoral approach. Conclusion: Anterolateral approaches are a viable and safe alternative for proximal humerus osteosynthesis with locking plate. Subacromial impingement was the most frequent complication.

Abstract
OBJECTIVE To evaluate the results after locking plate internal fixation of proximal humerus fractures by means of a motion capture system, and functional scales. MATERIAL AND METHOD Retrospective study of a cohort of 47 elderly patients undergoing surgery from January 2010 to December 2014. After a minimum follow-up of two years, two functional scales (Constant-Murley and Quick DASH), and a quality of life scale (EQ-5D) were used for clinical evaluation. For objective evaluation of the range of motion a kinematic marker-free analysis with cameras was performed. RESULTS The average age was 74.85 years. Average functional scores were: Constant-Murley 70.06 points, Quick DASH 35.74 points and EQ-5D 6.79 points. The average range of motion was: flexion, 111.49°; extension: 24.13°; abduction: 109.40°; adduction: 15.13°; external rotation: 38.96°, and internal rotation: 49.28°. Correlation was found between the two functional scales, between them and the EQ-5D, and between range of motion and functional scales (except for external rotation) as well as between range of motion and EQ-5D (except for flexion and external rotation). CONCLUSION Locking plate osteosynthesis in proximal humerus fragility fractures achieved good functional and quality of life scores. Motion capture systems can be a useful tool for the functional assessment of shoulder pathology allowing an objective evaluation of range of motion.

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.

Displaced humeral surgical neck fractures: classification and results of third-generation percutaneous intramedullary nailing. J Shoulder Elbow Surg 2019; 28:276-287. [PMID: 30429058 DOI: 10.1016/j.jse.2018.07.010] [Citation(s) in RCA: 25] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2017] [Revised: 06/28/2018] [Accepted: 07/03/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND The high rates of complications and reoperations observed with the early designs of first-generation (unlocked) and second-generation (bent design) humeral intramedullary nail (IMNs) have discouraged their use by most surgeons. The purpose of this study was to report the results of a third-generation (straight, locking, low-profile, tuberosity-based fixation) IMN, inserted through a percutaneous approach, for the treatment of displaced 2-part surgical neck fractures. METHODS We performed a retrospective review of 41 patients who underwent placement of a third-generation IMN to treat a displaced 2-part surgical neck fracture (AO/OTA type 11A3). The mean age at surgery was 57 years (range, 17-84 years). After percutaneous insertion through the humeral head, the IMN was used as a reduction tool. Static locking fixation was achieved after axial fracture compression ("back-slap" hammering technique). Patients were reviewed and underwent radiography with a minimum of 1 year of follow-up; the mean follow-up period was 26 months (range, 12-53 months). RESULTS Preoperatively, 3 types of surgical neck fractures were observed: with valgus head deformity (Type A = 8 cases), shaft translation without head deformity (Type B = 19 cases), or with varus head deformity (Type C = 14 cases). At final follow-up, all fractures went on to union, and the mean humeral neck-shaft angle was 132° ± 5°. We observed 2 malunions and 1 case of partial humeral head avascular necrosis. No cases underwent screw migration or intra-articular penetration. At last review, mean active forward elevation was 146° (range, 90°-180°) and mean external rotation was 50° (range, 20°-80°). The mean Constant-Murley score and Subjective Shoulder Value were 71 (range, 43-95) and 80% (range, 50%-100%), respectively. CONCLUSIONS Antegrade insertion of a third-generation IMN through a percutaneous approach provides a high rate of fracture healing, excellent clinical outcome scores, and a low rate of complications. No morbidity related to the passage of the nail through the supraspinatus muscle and the cartilage was observed. The proposed A, B, and C classification allows choosing the optimal entry point for intramedullary nailing.

Abstract
Background To identify the optimal viewing angles for every proximal screw in PHILOS plate-fixed proximal humeral fractures. Methods Three fresh-frozen human cadaveric bodies with six intact shoulders were studied. All three bodies were put in the beach chair position and PHILOS plates were placed on the proximal humerus. Head screws penetrating 1 mm into the joint were fitted one by one. Fluoroscopy was conducted in the 180° horizontal plane and the 120° coronal plane to analyze each screw’s penetration in every shoulder. Images were taken every 5°, then all images were analyzed to identify the sensitive angles. Results The range of optimal viewing angles to visualize penetration of every head screw was identified. In the coronal plane, the angles in the range between 0° and 10° were sensitive to all screws except No. 8 and No. 9. Furthermore, penetration of screws No. 8 and 9 could not be identified on any axillary view, but could be identified in the horizontal plane from − 30° to − 10° and from 10° to 35° respectively. Conclusions We recommend a 0°–10° axillary view with 30° arm abduction combined with two horizontal angles in the range of − 30° to − 10° and 10° to 35° for routine fluoroscopy during surgery. Our results will be helpful in avoiding primary screw penetration.

Abstract
Proximal humerus, humeral shaft, and distal humerus fractures are all common adult fractures, and often occur in older patients. While the treatment of proximal humerus fractures remains controversial, certain fractures benefit from plate fixation such as fracture-dislocations and head-split fractures. When plate fixation is chosen, anatomic reduction and restoration of the medial calcar are important for successful results. Further research is required to minimize complications and determine the optimal surgical candidates for plate fixation. Humeral shaft fractures are generally treated non-operatively. However, certain shaft fractures warrant plate fixation, such as open fractures, those with associated forearm fractures, and those in poly-trauma patients. Choice of surgical approach and plate depends on the location and type of the fracture. The majority of intra-articular distal humerus fractures should be treated with plate fixation. Dual plating is generally accepted as the gold standard treatment, while the optimal surgical approach and plate configuration requires more research.

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
OBJECTIVES To investigate proximal humerus locking plate fit in a large sample of human proximal humeri. METHODS A total of 97 cadaveric human humeri were selected. Humerus length, head diameter, and neck-shaft angle were measured. Three-hole and 5-hole 3.5-mm proximal humerus locking compression plates were affixed. A digital caliper was used to measure the maximum gap distance from the plate to the bone. Analysis of variance and student's t tests were conducted to evaluate differences in plate-bone distance between the 2 plate lengths, gender, race, age, and laterality. Correlation between plate-bone distance and humerus length, head diameter, and neck-shaft angle were determined. RESULTS Mean plate-bone distance for the 3-hole plate was 1.5 ± 0.6 mm (range 0.3-2.9 mm), and for the 5-hole plate was 2.5 ± 0.9 mm (range 0.7-5.0 mm) (P = 0.01). Female and right-sided humeri were shown to have significantly larger plate-bone gap distance when compared with counterparts (P = 0.01). No correlation was found between plate-bone gap distance and humeral length (R = 0.03), head diameter (R = 0.05), or neck-shaft angle (R = 0.08). CONCLUSION The proximal humerus locking plate was under-contoured and spanned all 97 specimens. Greater plate-bone distance was observed with the 5-hole plate versus the 3-hole plate. Applying the plate flush to bone may lead to medial displacement of the humeral head at the calcar increasing risk of loss of fracture fixation. In fractures with any metaphyseal comminution, malreduction will be more pronounced. Caution should be exercised when using the proximal humerus locking plate as a reduction aide.

Abstract
Objectives In this study, we investigated the correlation between fracture classification and secondary screw penetration. Methods We retrospectively identified 189 patients with displaced proximal humeral fractures treated by ORIF at our hospital between June 2006 and June 2013. All fractures were classified radiographically before surgery and follow-up for least 2 years after surgery was recommended. At each follow-up, radiographs were taken in three orthogonal views to evaluate secondary screw penetration. Results The study population consisted of 189 patients. Of these, 70 were male and 119 female, with a mean age of 59.1 years; the mean follow-up time was 28.5 months. Secondary screw penetration occurred in 26 patients. The risk of developing secondary screw penetration was 11.3-fold higher in four-part fractures than two-part fractures (P < 0.05), 8.6-fold higher for type C fractures than type A fractures (P < 0.05) and 11.0-fold higher for medial hinge disruption group than intact medial hinge group fractures (P < 0.05). However there was no difference between three-part fractures and two-part fractures (P = 0.374), and between type B and type A fractures (P = 0.195). Age, gender, time to surgery and the number of screw in humeral head had no influence on the secondary screw penetration rate (P > 0.05). Conclusions Patients with four-part fractures, type C fractures and medial hinges disruption are vulnerable to secondary screw penetration. This allows additional precautions to be instituted and measures to be taken as needed.

Abstract
BACKGROUND The aims of this study were to evaluate treatment failure and revision rates of proximal humeral fracture (PHF) treatment with a standardized treatment algorithm within the reality of a level-1 trauma center and to identify predictors of subsequent surgery. MATERIALS AND METHODS The medical database of a level-1 trauma center was screened for all primary treatments of PHFs between January 2009 and June 2012. Medical records and imaging were analyzed to identify the fracture morphology, pre-existing diseases, revision surgeries and treatment failures (conversion to another treatment). The patients were asked about subsequent surgeries by phone. A functional outcome questionnaire was mailed to participating patients. RESULTS Follow-up data were available for 423 of 521 patients (312 females, 111 males). The mean age at the time of primary treatment was 68.3 years; mean follow-up was 24.6 ± 12.3 months. The overall rate of mandatory re-operations was 15.6%, including a failure rate of 8.3%; another 7.6% of patients had additional arthroscopic surgeries. Treatment with anatomic hemi-prostheses was associated with the highest re-operation rates, and lowest outcomes. Involvement of the medial calcar region, complex fracture morphologies, cigarette smoking and alcohol-abuse were predictors for subsequent surgery. Patients without subsequent surgery had significantly higher functional outcome scores than patients with additional surgery. CONCLUSIONS With the use of a standardized treatment algorithm no treatment modality was at significantly higher risk for having additional surgery. Complex fracture types, involvement of the medial calcar, cigarette-smoking and alcohol-abuse were associated with subsequent surgeries. LEVEL OF EVIDENCE Level IV case series.

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.
