[Reduction techniques for minimally invasive stabilization of proximal humeral fractures]. OPERATIVE ORTHOPADIE UND TRAUMATOLOGIE 2019; 31:63-80. [PMID: 30683977 DOI: 10.1007/s00064-018-0586-0] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2018] [Revised: 08/21/2018] [Accepted: 08/23/2018] [Indexed: 10/27/2022]
Abstract
OBJECTIVE The aim of surgical stabilization of proximal humerus fractures is to restore the anatomical relations between the greater and lesser tubercle, to reconstruct the joint and preserve the vascular supply of the fragments. INDICATIONS Approximately 80% of proximal humeral fractures can be treated conservatively. Surgical treatment is indicated based on the fracture pattern, patient-related factors and the risk of avascular head necrosis. Two-part fractures with a metaphyseal comminution zone and 3/4-part fractures can benefit from near to anatomic reconstruction depending on the patient's demands and bone quality. Minimally invasive stabilization procedures allow for an anatomical reconstruction in the majority of fresh proximal humeral fractures with or without a proximal shaft fracture, provided that intraoperative traction allows the fracture to be aligned axially in the image intensifier by ligamentotaxis. Indirect, combined with direct reduction maneuvers, allow for an almost anatomical reconstruction, despite minimal invasive approaches. SURGICAL TECHNIQUE Beach chair position. The arm is held in a pneumatic articulating traction device. Evaluation of the indirect reduction potential by ligamentotaxis with visualization of the alignment of the head fragments in relation to the shaft by traction, abduction/adduction, flexion/extension and rotation. The traction device and a foam roll in the axilla to neutralize the tension of the pectoralis major and teres major muscles while simultaneously adducting the elbow hold the reduction. Insufficient reduction of the fragments requires additional direct reduction maneuvers. Opening of the bursa and fixation of the rotator cuff with sutures to adjust reposition. A 2.5 mm-threaded K‑wire is inserted into the head fragment as a joystick. Under protection of the axillary nerve, the plate is inserted under protection of the axillary nerve. Temporary fixation of the plate with Kirschner wires for positioning the plate 5-8 mm below the greater tubercle and 2-3 mm laterally of the sulcus of the long biceps tendon and subsequent radiographic control. Reduction of the shaft against the plate with a cortex screw. The threaded K‑wire in the head can be used to adjust the varus and valgus alignment and to achieve adequate support of the calcar. Finally, complete the osteosynthesis with angular stable screws. POSTOPERATIVE MANAGEMENT Immediate active assisted exercise in the shoulder under physiotherapeutic supervision. Temporary immobilization for patient comfort. Standard active and resistive mobilization after the first clinical and radiological checkup 6 weeks after surgery. Further radiological checks after 3 and 6 months and 1 year. No routine plate removal.

Inferomedial cortical bone contact and fixation with calcar screws on the dynamic and static mechanical stability of proximal humerus fractures. J Orthop Surg Res 2019; 14:1. [PMID: 30606215 PMCID: PMC6318990 DOI: 10.1186/s13018-018-1031-7] [Citation(s) in RCA: 83] [Impact Index Per Article: 16.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/09/2018] [Accepted: 12/06/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND This study aimed to explore the effect of retaining inferomedial cortical bone contact and fixation with calcar screws on the dynamic and static mechanical stability of proximal humerus fractures treated with a locking plate. METHODS Twelve Synbone prosthetic humeri (SYNBONE-AG, Switzerland) were used for a wedge osteotomy model at the proximal humerus, in four groups. In the cortex contact + screw fixation group and cortex contact group, the inferomedial cortical bone contact was retained. In the screw fixation group and control group, the inferomedial cortical bone contact was not retained. Calcar screw fixation was implemented only in the screw fixation groups. The dynamic and static mechanical stability of the models were tested with dynamic fatigue mechanics testing, quasi-static axial compression, three-point bending, and torsion testing. RESULTS The cortex contact + screw fixation group showed the longest fatigue life and the best stability. There was 35% difference in fatigue life between the cortex contact + screw fixation group and the cortex contact group, 43%between the cortex contact + screw fixation group and screw fixation group, and 63% between the cortex contact + screw fixation group and screw fixation group (P < 0.01). The cortex contact + screw fixation group showed the best axial compressive stiffness, bending stiffness, and torsion stiffness; these were successively decreased in the other three groups (P < 0.01). CONCLUSION Retaining inferomedial cortical bone contact and fixation with two calcar screws maintained fracture stability with the highest strength and minimum deformation. Of the two methods, restoration of the inferomedial cortical bone support showed better dynamic and static biomechanical properties than placement of calcar screws alone.

Geriatr Orthop Surg Rehabil 2018; 9:2151459318818163. [PMID: 30627472 PMCID: PMC6311545 DOI: 10.1177/2151459318818163] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2018] [Revised: 11/14/2018] [Accepted: 11/15/2018] [Indexed: 11/15/2022] Open
Abstract
Background Although proximal humerus strength/quality can be assessed using cortical thickness measurements (eg, cortical index), there is no agreement where to make them. Tingart and coworkers used measurements where the proximal endosteum becomes parallel, while Mather and coworkers used measurements where the periosteum becomes parallel. The new circle-fit method (CFM) makes 2 metaphyseal (M1-M2) and 6 diaphyseal (D1-D6) measurements referenced from humeral head diameter (HHD). However, it is unknown whether these locations correlate to humeral length (HL). Accordingly, we asked: (1) Does HHD, Tingart distance, and Mather distance correlate with HL? (2) What is the location of HHD, Tingart distance, and Mather distance as a percentage of HL? and (3) Which CFM D1-D6 locations correlate with Tingart and Mather distances? Materials and Methods Measurements made on cortical thickness (CT) scout views of 19 humeri (ages: 16-73 years) included HHD, distances from the superior aspect of the humerus to proximal Tingart and Mather locations, and HL. Results Intraclass correlation was excellent for CFM-HHD, poor for Tingart, and moderate for Mather. The CFM-HHD had a stronger correlation to HL than Tingart and Mather. Mean HHD was 15.5% (0.9%) of HL while Tingart was 27.0% (4.1%) and Mather was 23.2% (3.8%). Tingart distance corresponded to D2/D3 CFM locations while the Mather distance was similar to D1/D2. Discussion The CFM reliably correlates with HL and provides a stronger correlation and less variance between specimens than the Tingart or Mather Methods. Conclusions Because the CFM produces reliable percent of HL locations, it should be used to define locations for obtaining biomechanically relevant CT measurements such as cortical index. Stronger correlations of these CFM-based measurements with proximal humerus strength will be important for developing advanced algorithms for fracture treatment.

Abstract
BACKGROUND Metal plates are the fixation devices used most frequently to proximal humeral fractures (PHFs). However, in recent years carbon fiber-reinforced polyetheretherketone (CFR-PEEK) plates have become increasingly common. This study compares the clinical and radiographic outcomes of 42 Neer three- and four-part PHFs treated with CFR-PEEK or metal (titanium) plates. MATERIALS AND METHODS Forty-two PHF patients were managed with CFR-PEEK plates (n = 21, males/females 9/12; mean age 57.4 years; mean follow-up 30.7 months; CFR-PEEK group) or metal plates (n = 21; males/females 7/14; mean age 55.8 years; mean follow-up 52.7 months; Metal group). Active shoulder mobility (anterior elevation, lateral elevation, external rotation, and internal rotation), the Constant-Murley Score, the Simple Shoulder Test Score, and the pain score were recorded. Preoperative computed tomography scans and X-rays were obtained. Postoperative fracture healing and displacement, tuberosity resorption and/or malposition, hardware position, and cortical thinning (CT) under the plate were assessed radiographically. RESULTS Shoulder mobility, clinical, and pain scores were similar in both patient groups. CT was significantly greater in CFR-PEEK patients (mean difference, 1.14 mm; p = 0.0003). In both groups, incomplete or poor calcar reduction was associated to a significantly higher complication rate, especially stiffness and muscle weakness (p = 0.016). The rate of tuberosity resorption was significantly higher in the Metal group (p = 0.040). Two patients required revision to a hemiarthroplasty (CFR-PEEK) and reverse arthroplasty (Metal group). CONCLUSIONS CFR-PEEK plates provide a viable alternative to conventional titanium plates in PHFs, ensuring similar clinical outcomes and a lower rate of tuberosity resorption, but they involve higher stress shielding under the plate.

Abstract
Background Technical aspects of the correct placement of medial support locking screws in the locking plate for proximal humerus fractures remain incompletely understood. This study was to evaluate the clinical relationship between the number of medial support screws and the maintenance of fracture reduction after locked plating of proximal humerus fractures. Methods We retrospectively evaluated 181 patients who had been surgically treated for proximal humeral fractures (PHFs) with a locking plate between September 2007 and June 2013. All cases were then subdivided into one of four groups as follows: 75 patients in the medial cortical support (MCS) group, 26 patients in the medial multiscrew support (MMSS) group, 29 patients in the medial single screw support (MSSS) group, and 51 patients in the no medial support (NMS) group. Clinical and radiographic evaluations included the Constant-Murley score (CM), visual analogue scale (VAS), complications, and revision surgeries. The neck-shaft angle (NSA) was measured in a true anteroposterior radiograph immediately postoperation and at final follow-up. One-way analysis of variance or Kruskal-Wallis test was used for statistical analysis of measurement data, and Chi-square test or Fisher's exact test was used for categorical data. Results The mean postoperative NSAs were 133.46° ± 6.01°, 132.39° ± 7.77°, 135.17° ± 10.15°, and 132.41° ± 7.16° in the MCS, MMSS, MSSS, and NMS groups, respectively, and no significant differences were found (F = 1.02, P = 0.387). In the final follow-up, the NSAs were 132.79° ± 6.02°, 130.19° ± 9.25°, 131.28° ± 12.85°, and 127.35° ± 8.50° in the MCS, MMSS, MSSS, and NMS groups, respectively (F = 4.40, P = 0.008). There were marked differences in the NSA at the final follow-up between the MCS and NMS groups (P = 0.004). The median (interquartile range [IQR]) NSA losses were 0.0° (0.0-1.0)°, 1.3° (0.0-3.1)°, 1.5° (1.0-5.2)°, and 4.0° (1.2-7.1)° in the MCS, MMSS, MSSS, and NMS groups, respectively (H = 60.66, P < 0.001). There were marked differences in NSA loss between the MCS and the other three groups (MCS vs. MMSS, Z = 3.16, P = 0.002; MCS vs. MSSS, Z = 4.78, P < 0.001; and MCS vs. NMS, Z = 7.34, P < 0.001). There was also significantly less NSA loss observed in the MMSS group compared to the NMS group (Z = -3.16, P = 0.002). However, there were no significant differences between the MMSS and MSSS groups (Z = -1.65, P = 0.225) or the MSSS and NMS groups (Z = -1.21, P = 0.099). The average CM scores were 81.35 ± 9.79, 78.04 ± 8.97, 72.76 ± 10.98, and 67.33 ± 12.31 points in the MCS, MMSS, MSSS, and NMS groups, respectively (F = 18.68, P < 0.001). The rates of excellent and good CM scores were 86.67%, 80.77%, 65.52%, and 43.14% in the MCS, MMSS, MSSS, and NMS groups, respectively (χ2 = 29.25, P < 0.001). The median (IQR) VAS scores were 1 (0-2), 1 (0-2), 2 (1-3), and 3 (1-5) points in the MCS, MMSS, MSSS, and NMS groups, respectively (H = 27.80, P < 0.001). Functional recovery was markedly better and VAS values were lower in the MCS and MMSS groups (for CM scores: MCS vs. MSSS, P < 0.001; MCS vs. NMS, P < 0.001; MMSS vs. MSSS, P = 0.031; and MMSS vs. NMS, P < 0.001 and for VAS values: MCS vs. MSSS, Z = 3.31, P = 0.001; MCS vs. NMS, Z = 4.64, P < 0.001; MMSS vs. MSSS, Z = -2.09, P = 0.037; and MMSS vs. NMS, Z = -3.16, P = 0.003). Conclusions Medial support screws might help enhance mechanical stability and maintain fracture reduction when used to treat PHFs with medial metaphyseal comminution or malreduction.

Abstract
BACKGROUND There is no consensus on the choice of treatment for displaced proximal humeral fractures in older patients (aged > 65 years). The aims of this systematic review and meta-analysis were (1) to compare operative with nonoperative management of displaced proximal humeral fractures and (2) to compare effect estimates obtained from randomized controlled trials (RCTs) and observational studies. METHODS The databases of MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and CINAHL (Cumulative Index to Nursing and Allied Health Literature) were searched on September 5, 2017, for studies comparing operative versus nonoperative treatment of proximal humeral fractures; both RCTs and observational studies were included. The criteria of the Methodological Index for Non-Randomized Studies, a validated instrument for methodologic quality assessment, were used to assess study quality. The primary outcome measure was physical function as measured by the absolute Constant-Murley score after operative or nonoperative treatment. Secondary outcome measures were major reinterventions, nonunion, and avascular necrosis. RESULTS We included 22 studies, comprising 7 RCTs and 15 observational studies, resulting in 1743 patients in total: 910 treated operatively and 833 nonoperatively. The average age was 68.3 years, and 75% of patients were women. There was no difference in functional outcome between operative and nonoperative treatment, with a mean difference of -0.87 (95% confidence interval, -5.13 to 3.38; P = .69; I2 = 69%). Major reinterventions occurred more often in the operative group. Pooled effects of RCTs were similar to pooled effects of observational studies for all outcome measures. CONCLUSIONS We recommend nonoperative treatment for the average elderly patient (aged > 65 years) with a displaced proximal humeral fracture. Pooled effects of observational studies were similar to those of RCTs, and including observational studies led to more generalizable conclusions.

Abstract
UNLABELLED Humeral fractures are not well understood and thus we examined the incidence and outcomes of elderly humeral fractures at a single institution over a 3-year period. We found increasing incidence in humeral fractures with increasing age and negative outcomes comparable to hip fractures. INTRODUCTION In this study, we report the incidence of humeral fractures in the older patient and their outcomes, including new nursing homes discharges and mortality, residing in the metropolitan referral area of a Sydney tertiary referral hospital. METHODS All admissions between 2013 and 2016, of patients aged 65 years or more, presenting to hospital with humeral fractures were reviewed. The data was explored primarily for outcomes (mortality and new admissions to residential aged care facility) and secondarily for clinical association with humeral fractures. RESULTS Two hundred eighty-one episodes of humeral fracture were identified. Incidence peaked in the above 85-year-old group at 670 per 100,000 persons per year. Proximal fractures were accounted for 84.3% of the cohort. 12.8% received operative management. The in-hospital mortality rate was 3.6%. Gender was a significant predictor for mortality (OR = 5.8, 95% CI 1.3-28.5, p value = 0.0032) with males six times more likely to experience in-hospital mortality compared to females. 17.8% of participants were admitted to a new nursing home. Logistical regression demonstrated age (OR = 1.10, 95% CI 1.04-1.17; p value = 0.001) and Charlson comorbidity index (OR = 1.32, 95% CI 1.04-1.66; p value = 0.02) were predictors of admission to a new nursing home. CONCLUSION Humeral fractures are common in the older population and cause a substantial amount of new nursing home admissions and mortality. Further study is required to ascertain appropriate guidelines for treatment and rehabilitation.

Abstract
CASE An 80-year-old woman sustained a fracture-dislocation of the proximal aspect of the humerus with a near-complete brachial plexopathy, which was successfully managed acutely using a reverse shoulder arthroplasty (RSA) with repair of the greater and lesser tuberosities. The palsy, which was confirmed with nerve conduction studies, recovered uneventfully along with functional improvement of the shoulder. At the most recent follow-up, there was complete resolution of the plexopathy, with excellent, pain-free range of motion. CONCLUSION Acute RSA with tuberosity repair may be a reasonable treatment modality in the setting of an acute brachial plexus palsy following a comminuted fracture-dislocation of the proximal aspect of the humerus in an elderly patient.

Abstract
Background Fractures of the proximal humerus are among the most common long-bone fractures and present unique challenges to surgeons. Traditional internal fixation methods, such as intramedullary nails, are associated with drawbacks such as an inability to fully fill the trabecular space and a limited ability to utilize supplemental hardware in many cases. We evaluated the safety and effectiveness of a novel fracture fixation device that utilizes a light-cured monomer to stabilize the fracture in a cohort of patients suffering from humerus fractures. Methods We prospectively collected data from patients being treated surgically for humerus fractures. Fractures were treated using the photodynamic bone stabilization system (PBSS) consisting of a balloon and light-cured monomer. Patients were evaluated at 7-14, 30, 60, 90, 180, and 360 days post-procedure. Primary outcomes included normal and complete radiographic fracture healing. Secondary outcomes included pain (via visual analog scale), function (via the disability of the arm, shoulder, and hand (DASH) and constant shoulder scales), and the rate of complications. Results A total of 33 patients were included in the intent-to-treat analysis (mean age: 76.6 yrs). Of these patients, 88% demonstrated normal radiographic healing at their 90-, 180-, and 360-day visits. Complete radiographic healing was observed in 81%, 88%, and 96% of patients at 90, 180, and 360 days, respectively. Pain scores decreased significantly at day seven when compared with baseline (28.2+20.9 vs.53.6+32.2, p<0.001) and continued to decrease at the 90-day (24.7+15.5, p<0.001), 180-day (17.8+12.5, p<0.001) and 360-day (6.6+6.7, p<0.001) evaluations. DASH scores demonstrated statistically significant improvements over baseline (65.5+31.5) at 90 (37.0+14.9, p<0.001), 180 (30.6+15.7, p<0.001), and 360 days (23.9+15.0, p<0.001) post-procedure. The procedure-related event rate was 36.4%, with 5 (11.4%) device-related adverse events reported at the one-year follow-up. Conclusions Our study demonstrates the ability of a novel internal fixation device to safely and effectively treat fractures of the humerus in the elderly population.

Abstract
Proximal humerus fractures constitute a significant percentage of fragility fractures. The growing use of locking plate has helped treat this problem, but at the same time has brought about complications. Past systematic reviews have documented these complications, however a large number of recent studies have been published since, reporting their own complication rates with different techniques. This study reviews the current complications associated with locking plate of proximal humerus fractures as well as methods to reduce them. A systematic review, following the PRISMA guidelines, was conducted in November 2013 and repeated in March 2015, using PubMed, Scopus, and Cochrane databases, to evaluate locking plate fixation (and complications) of traumatic proximal humerus fractures. Inclusion criteria included adults (>18 years), minimum of 12-month postoperative followup, articles within the last 5 years, and studies with >10 participants. Exclusion criteria included pathologic fractures, cadaveric studies, and nonhuman subjects. Eligible studies were graded using a quality scoring system. Articles with a minimum of 7/10 score were included and assessed regarding their level of evidence per the Journal of Bone and Joint Surgery and Centre for Evidence-Based Medicine guidelines. The initial query identified 51,206 articles from multiple databases. These records were thoroughly screened and resulted in 57 articles, consisting of seven Level 1, three Level 2, 10 Level 3, and 37 Level 4 studies, totaling 3422 proximal humerus fractures treated with locking plates. Intraarticular screw penetration was the most reported complication (9.5%), followed by varus collapse (6.8%), subacromial impingement (5.0%), avascular necrosis (4.6%), adhesive capsulitis (4.0%), nonunion (1.5%), and deep infection (1.4%). Reoperation occurred at a rate of 13.8%. Collapse at the fracture site contributed to a majority of the implant-related complications, which in turn were the main reasons for reoperation. The authors of these studies discussed different techniques that could be used to address these issues. Expanding use of locking plate in the proximal humerus fractures leads to improvements and advancements in surgical technique. Further research is necessary to outline indications to decrease complications, further.

Abstract
BACKGROUND Literature lacks data concerning several epidemiologic aspects of proximal humeral fractures (PHFs). METHODS This retrospective study included 711 consecutive patients (209 men, 502 women) who sustained a PHF in the last 3 years. Participants were divided into 2 groups, adults and children. Data regarding age, sex, date, and fracture side were collected. According to the mechanism of injury, we arbitrarily distinguished 7 subgroups. PHFs were classified according to the head-greater-lesser-shaft (HGLS)-Hertel classification and to the Salter-Harris classification using x-ray and computed tomography imaging. RESULTS PHFs represent 5.03% of the overall fractures. The right side was involved in 389 patients (54.7%; P = .6). The mean age of male and female patients was 55.4 (standard deviation, 21.9) years and 67.0 (standard deviation, 16.1) years, respectively (P = .0001). Significant differences in the trauma mechanism between female patients (street/home low-energy trauma) and male patients (high-energy trauma) were found. A significant correlation between trauma mechanisms from 1 to 5 and fracture patterns H-G-L-S, HL-G-S, HGL-S, and HLS-G was observed. The occurrence of the same patterns significantly varied according to different age subgroups. Considering the pediatric population, a significant incidence of Salter-Harris 2 in both genders was found. No correlation was observed between the fracture patterns and the trauma mechanism. CONCLUSIONS PHFs have a higher prevalence and incidence in females and in older age, respectively; they are more frequent in the winter months. In addition, male fractures are due to different traumatic events than those in females. A correlation between trauma and PHF pattern was evident only for adults. Some fracture patterns are correlated with different ranges of age in all patients.

Abstract
Proximal humeral fractures are common and most challenging, due to the complexity of the glenohumeral joint, especially in the geriatric population with impacted fractures, that the development of implants continues because currently the problems with their fixation are not solved. Pre-, intra-, and postoperative assessments are crucial in management of those patients. Finite element analysis, as one of the valuable tools, has been implemented as an effective and noninvasive method to analyze proximal humeral fractures, providing solid evidence for management of troublesome patients. However, no review article about the applications and effects of finite element analysis in assessing proximal humeral fractures has been reported yet. This review article summarized the applications, contribution, and clinical significance of finite element analysis in assessing proximal humeral fractures. Furthermore, the limitations of finite element analysis, the difficulties of more realistic simulation, and the validation and also the creation of validated FE models were discussed. We concluded that although some advancements in proximal humeral fractures researches have been made by using finite element analysis, utility of this powerful tool for routine clinical management and adequate simulation requires more state-of-the-art studies to provide evidence and bases.

Abstract
UNLABELLED Proximal humeral fracture is the third most common osteoporotic fracture. To our knowledge, this is the first nationwide population-based registry study in adults that includes both inpatient and outpatient visits. Thus, we were able to report the true incidence rates and trends in the treatment of proximal humeral fractures. INTRODUCTION Proximal humeral fractures are among the most common osteoporotic fractures. Valid epidemiologic population-based data, including both inpatient and outpatient visits, however, are lacking. METHODS To investigate the Swedish national incidence rates and treatment trends of proximal humeral fractures, we obtained data from the Swedish Hospital Discharge Register between 2001 and 2012. All adult patients (≥18 years of age) in the Swedish Hospital Discharge Register were included. Outpatient visits have been included in the register since 2001. RESULTS We identified 98,770 patients (women n = 72,063; 73 %) with proximal humeral fractures between 2001 and 2012. In 2001, the sex-specific incidence of proximal humeral fractures was 134.5 per 100,000 person-years for women and 49.2 for men. In 2012, the corresponding values were 174.6 for women and 68.1 for men, increasing 30 % in women and 39 % in men. A total of 17,013 surgical procedures were conducted between 2001 and 2012. Open reduction and internal fixation with a plate was the most common procedure (n = 5050, 30 %), followed by endoprosthetic implantation (n = 3962, 23 %) and intramedullary nailing (n = 3376, 20 %). The proportion of surgically treated patients increased from 12.1 % in 2001 to 16.8 % in 2012 for women and from 15.1 % in 2001 to 17.1 % in 2012 for men. CONCLUSION The Swedish national incidence of proximal humeral fractures has been increasing, although it seems to have peaked in the elderly population during 2008-2010. The rate of surgical treatment has increased substantially, particularly open reduction and internal fixation with a plate. To our knowledge, this is the first nationwide epidemiologic study for Sweden reporting the incidence of proximal humeral fractures and including all inpatient and outpatient visits.

Arch Orthop Trauma Surg 2017; 137:1385-1390. [PMID: 28756586 PMCID: PMC5602045 DOI: 10.1007/s00402-017-2767-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2017] [Indexed: 11/10/2022]
Abstract
INTRODUCTION Straight antegrade humeral nailing (SAHN) has become a standard technique for the surgical fixation of proximal humeral fractures, which predominantly affect elderly females. The nail's proximal anchoring point has been demonstrated to be critical to ensure reliable fixation in osteoporotic bone and to prevent iatrogenic damage to the superior rotator cuff bony insertion. Anatomical variations of the proximal humerus, however, may preclude satisfactory anchoring of the nail's proximal end and may bare the risk of rotator cuff violation, even though the nail is inserted as recommended. The aim of this study was to evaluate the anatomical suitability of proximal humeri of geriatric females aged 75 years and older for SAHN. Specifically, we sought to assess the proportion of humeri not anatomically amenable to SAHN for proximal humeral fracture. MATERIALS AND METHODS A total of 303 proximal humeri of 241 females aged 75 years and older (mean age 84.5 ± 5.0 years; range 75-102 years) were analyzed for this study. Multiplanar two-dimensional reformations (true ap, true lateral, and axial) were reconstructed from shoulder computed tomography (CT) data sets. The straight antegrade nail's ideal entry point, "critical point" (CP), and critical distance (CD; distance between ideal entry point and CP) were determined. The rate of proximal humeri not anatomically suitable for SAHN (critical type) was assessed regarding proximal reaming diameters of currently available straight antegrade humeral nails. RESULTS Overall, 35.6% (108/303) of all proximal humeri were found to be "critical types" (CD <8 mm) as to the recommended minimal proximal reaming diameter of 10 mm of straight antegrade nails currently in use. Moreover, 43.2% (131/303) of the humeri were considered "critical types" with regard to the alternatively used larger proximal reaming diameter of 11.5 mm. Mean CD was 9.0 ± 1.7 mm (range 3.5-13.5 mm) and did not correlate with age (r = -0.04, P = 0.54). No significant differences in CD and rate of "critical types" were found between left and right humeri as well as between females aged between 75 and 84 years (n = 151) and females aged 85 and older (n = 152). CONCLUSIONS More than a third of proximal humeri of geriatric females are "critical types" as to SAHN and may, therefore, be at risk for procedure-related complications, such as rotator cuff violation, fixation failure, and potential malreduction. In view of this finding, we recommend to routinely analyze multiplanar CT reformations of the uninjured contralateral side prior to surgery to improve selection of patients for SAHN and to minimize foreseeable complications. For "critical type" humeri, an alternative surgical procedure should be considered.

Abstract
INTRODUCTION The treatment of 3and 4 part proximal humeral fractures in elderly patients is still controversial. The frequent co-existence of poor quality bone and rotator cuff abnormalities in patients with multiple clinical conditions and with difficulties for physical rehabilitation leads to disappointing clinical results, even when the radiological images are acceptable. OBJECTIVE To evaluate the clinical, radiological, and functional results in patients over 65 years old with complex proximal humerus fractures treated with reverse shoulder arthroplasty. MATERIAL AND METHODS A prospective review was carried out on 30 patients (26 women and 4 men) with proximal humeral fractures treated with reverse shoulder arthroplasty in our department. The mean age was 74.9 years (SD=6.3), and the mean follow-up was 34.5 months (SD=19.3). RESULTS Clinical and functional results were acceptable, with a mean forward flexion of 124° and a mean external rotation of 13°. The mean abbreviated Constant abbreviated score was 49.1 (SD=14.1), 27 (SD=6.3) in the UCLA scale, and 32.2 (SD=19.2) in the QuickDASH questionnaire. The large majority (80%) of the patients are pain free, and they do not need medication to do daily activities. The complication rate was 13.3%. CONCLUSIONS We consider that reverse shoulder arthroplasty is a valid option to treat 3and 4 part proximal humeral fractures in elderly patients. The surgical goals should include the anatomical reconstruction of the tuberosities, avoiding enlargement of the operated arm greater than 2cm.

Abstract
BACKGROUND AND PURPOSE Proximal humerus fractures are common fragility injuries. The incidence of these fractures has been estimated to be 82-105 per 105 person-years. Treatment of this fracture, especially in the elderly, is controversial. Our study group published a systematic review of the available literature and concluded that non-operative methods are favored over operative methods in three- and four-part fractures. The aim of this multinational study was to compare treatment policies for proximal humerus fractures among the Nordic countries and Estonia. MATERIALS AND METHODS The study was conducted as a questionnaire-based survey, using the Internet-based program, Webropol(®) (webropol.com). The questionnaire link was sent to the surgeons responsible for treating proximal humerus fractures in major public hospitals in Estonia, Finland, Norway, and Sweden. Questionnaire included questions regarding the responder's hospital, patient characteristics, and examinations taken before decision making. Clinical part included eight example patient cases with treatment options. RESULTS Of the 77 recipients of the questionnaire, 59 responded; consequently, the response rate was 77%. Based on the eight presented displaced fracture examples, in both Estonia and Norway and in Finland, 41% and 38%, respectively, preferred surgical treatment with locking plate. In Sweden, the percentage was 28%. The pre- and post-operative protocols showed a similarity in all participant countries. CONCLUSION Our survey revealed a remarkable uniformity in the current practice of operative treatments and rehabilitation for proximal humerus fractures in the participant countries.

Abstract
UNLABELLED After surgical fixation, osteoporotic proximal humeral fractures often show high impaction and loss of reduction. This study aims at assessing the amount of impaction and loss of reduction at a short and medium follow-up. We found an alarming percentage of cases showing these complications in the first postoperative months. INTRODUCTION This study seeks to quantify the amount of humeral head impaction and loss of reduction in a consecutive series of osteoporotic proximal humerus fractures treated with a locking plate. METHODS A series of displaced proximal humerus fractures were prospectively treated with minimally invasive reduction and ostheosynthesis using a locking plate. Diagnosis and classification of fractures were based on X-ray examination and CT scan. Proximal humerus cortical bone thickness (CBTAVG) was studied to assess osteoporosis. Amount of loss of reduction and head fragment impaction were noted at 3 and 18 months of follow-up. Constant score was calculated at 6 and 18 months of follow-up. RESULTS Thirty-one osteoporotic fractures were studied. Most of the fractures (21, 67.7 %) had a CBTAVG of less than 4 mm. At 3 months of follow-up, 7 cases (22.5 %) had significant loss of reduction and the mean amount of impaction was 2.8 mm. At 18 months of follow-up, only 1 additional fracture showed loss of reduction and mean impaction was 3 mm (p < 0.05). At 6 months follow-up, the mean Constant score was 58 %; while at 18 months, it was 70 % (p = 0.02). Amount of impaction was significantly correlated to age of patients (p = 0.031), female sex (p = 0.011), CBTAVG (p = 0.019), and metaphyseal comminution (p = 0.013). CONCLUSIONS Osteoporotic proximal humerus fractures may present an important impaction and loss of reduction in the first 3 months after surgery even if treated with a rigid device and multiple head screws. Surgeons treating these osteoporotic fractures should be aware of these complications even when using a rigid device.
