Abstract
Background: The morphology of proximal humeral fractures (PHFs) is complex, and the fixation and selection of implants need to be guided by the fracture type and classification, which requires an accurate understanding of the fracture line. This study had three purposes. 1) Define and analyze the fracture lines and morphological features of all types PHFs by three-dimensional (3D) mapping technology. 2) Determine the osteotomy position of the biomechanical model of the PHFs according to the fracture heat map. 3) Based on the analysis of the pathological morphology and distribution of a large number of consecutive cases of PHFs, propose a novel classification of PHFs. Methods: We retrospectively collected 220 cases of PHFs and generated a 3D fracture map and heat map based on computed tomography (CT) imaging. Through analysis of the fracture morphology of the 220 PHFs, a novel classification was proposed. The primary criterion for staging was the continuity between the humeral head and the greater tuberosity and lesser tuberosity, and the secondary criterion was the relationship between the humeral head segment and the humeral shaft. Results: The fracture line was primarily found around the metaphyseal zone of region of the surgical neck, with the most extensive distribution being below the larger tuberosity and on the posterior medial side of the epiphysis. We suggest that the osteotomy gap should be immediately (approximately 5-10 mm) below the lower edge of the articular surface. The most common type of fracture was type I3 (33 cases, 15.0%), followed by type IV3 fracture (23 cases, 10.4%), and type III2 fracture (22 cases, 10.0%). Interobserver and intraobserver reliability analysis for the fracture classification revealed a k value (95% confidence interval) of 0.639 (0.57-0.71) and 0.841, P < 0.01, respectively. Conclusion: In this study, the fracture line and morphological characteristics of PHFs were clarified in detail by 3D mapping technique. In addition, a new classification method was proposed by analysis of the morphological characteristics of 220 PHFs, A two-part fracture model for PHFs is also proposed.

Abstract
Background Proximal humerus fractures are a common injury, predominantly affecting older adults. This study aimed to develop risk-prediction models for prolonged length of hospital stay (LOS), serious adverse complications, and readmission within 30 days of surgically treated proximal humerus fractures using machine learning (ML) techniques. Methods Adult patients (age >18) who underwent open reduction internal fixation (ORIF), hemiarthroplasty, or total shoulder arthroplasty for proximal humerus fracture between 2016 and 2021 were included. Preoperative demographic and clinical variables were collected for all patients and used to establish ML-based algorithms. The model with optimal performance was selected according to area under the curve (AUC) on the receiver operating curve (ROC) curve and overall accuracy, and the specific predictive features most important to model derivation were identified. Results A total of 7473 patients were included (72.1% male, mean age 66.2 ± 13.7 years). Models produced via gradient boosting performed best for predicting prolonged LOS and complications. The model predicting prolonged LOS demonstrated good discrimination and performance, as indicated by (Mean: 0.700, SE: 0.017), recall (Mean: 0.551, SE: 0.017), accuracy (Mean: 0.717, SE: 0.010), F1-score (Mean: 0.616, SE: 0.014), AUC (Mean: 0.779, SE: 0.010), and Brier score (Mean: 0.283, SE: 0.010) Preoperative hematocrit, preoperative platelet count, and patient age were considered the strongest predictive features. The model predicting serious adverse complications exhibited comparable discrimination [precision (Mean: 0.226, SE: 0.024), recall (Mean: 0.697, SE: 0.048), accuracy (Mean: 0.811, SE: 0.010), F1-score (Mean: 0.341, SE: 0.031)] and superior performance relative to the LOS model [AUC (Mean: 0.806, SE: 0.024), Brier score (Mean: 0.189, SE: 0.010), noting preoperative hematocrit, operative time, and patient age to be most influential. However, the 30-day readmission model achieved the weakest relative performance, displaying low measures of precision (Mean: 0.070, SE: 0.012) and recall (Mean: 0.389, SE: 0.053), despite good accuracy (Mean: 0.791, SE: 0.009). Conclusion Predictive models constructed using ML techniques demonstrated favorable discrimination and satisfactory-to-excellent performance in forecasting prolonged LOS and serious adverse complications occurring within 30 days of surgical intervention for proximal humerus fracture. Modifiable preoperative factors such as hematocrit and platelet count were identified as significant predictive features, suggesting that clinicians could address these factors during preoperative patient optimization to enhance outcomes. Overall, these findings highlight the potential for ML techniques to enhance preoperative management, facilitate shared decision-making, and enable more effective and personalized orthopedic care by exploring alternative approaches to risk stratification.

Abstract
PURPOSE 3- and 4-part proximal humeral fractures are frequently treated conservatively. This study aims to combine radiographic, and patient reported outcome data to identify factors leading to poor outcomes following conservative treatment. METHODS A retrospective local database analysis identified 3- and 4-part fractures. Radiographic and functional outcomes including Oxford Shoulder Score (OSS), QuickDash (QD), Subjective Shoulder Score (SSV) and VAS pain scores were collected. RESULTS 104 patients were included at mean follow-up of 55 months. Analysis highlighted significant OSS differences in 3- versus 4-part (p = 0.027), dominant arm injury (p = 0.046), age > 65 (p = 0.006), varus coronal neck-shaft angle < 115 versus 115-155 degrees (p = 0.008), posterior head tilt > 155 degrees (p = 0.005), greater tuberosity (GT) displacement > 5 mm (p = 0.001), GT comminution (p = 0.01), medial calcar hinge displacement > 2 mm (p = 0.032). According to QD scores; age > 65 (p = 0.012), varus neck-shaft angle (p = 0.01), GT displacement > 5 mm (p = 0.001), GT comminution (p = 0.01), medial calcar hinge displacement > 2 mm (p = 0.006). SSV varied significantly with 3- versus 4-part fractures (p = 0.005), age > 65 (p = 0.04), varus neck-shaft angle (p = 0.001), posterior head tilt (p = 0.005), GT displacement > 5 mm (p = 0.001), GT comminution (p = 0.003), and medial calcar hinge displacement > 2 mm (p = 0.001). CONCLUSION We highlight risk factors for unfavourable outcomes following conservative management, aiding surgeons in shared decision-making and patient expectation management.

Abstract
This study aims to provide an updated review comparing the complication rates and clinical outcomes of intramedullary nails and locking plates (LPs) in displaced proximal humerus fracture (PHF) management. We performed a systematic review of the Cochrane Central Register of Controlled Trials, Clinical Trials Registry, EMBASE, and PubMed. Studies with level III evidence or higher comparing intramedullary nails and LPs used for internal fixation of displaced PHFs were included. The Methodological Index for Nonrandomized Studies (MINORS) criteria and Cochrane Handbook for Systematic Reviews of Interventions 5.2.0 were used to assess the risk of bias. Our meta-analysis included a comparison of method-related complications, pain scores, range of motion (ROM), and functional scores. A total of 13 comparative studies were included: five randomized controlled trials, three prospective cohort studies, and five retrospective cohort studies. The total number of patients included was 1,253 (677 in the LP group and 576 in the intramedullary nail group). Superior Constant-Murley scores and external rotation ROM were found in the LP group during the early postoperative period. However, long-term functional scores and complication rates were comparable between the two groups. We conclude that intramedullary nailing and LP fixation are both equally effective for the treatment of displaced PHFs. Neither treatment appears superior at this time, and more large-scale randomized controlled trials should be conducted to further evaluate the potential benefit of LPs in the early postoperative period.

Abstract
INTRODUCTION The purpose of this study was to perform a systematic review and meta-analysis of both randomized controlled and observational studies comparing surgical interventions for proximal humerus fractures. METHODS Systematic review of Medline, Embase, Scopus, and Google Scholar, including all level 1-3 studies from 2000 to 2022 comparing surgical treatment with ORIF, IM nailing, hemiarthroplasty, total and reverse shoulder arthroplasty (RTS) was conducted. Clinical outcome scores, range of motion (ROM), and complications were included. Risk of bias was assessed using the Cochrane Collaboration's ROB2 tool and ROBINs-I tool. The GRADE system was used to assess the overall quality of the body of evidence. Heterogeneity was assessed using χ2 and I2 statistics. RESULTS Thirty-five studies were included in the analysis. Twenty-five studies had a high risk of bias and were of low and very low quality. Comparisons between ORIF and hemiarthroplasty favored ORIF for clinical outcomes (p = 0.0001), abduction (p = 0.002), flexion (p = 0.001), and external rotation (p = 0.007). Comparisons between ORIF and IM nailing were not significant for clinical outcomes (p = 0.0001) or ROM. Comparisons between ORIF and RTS were not significant for clinical outcomes (p = 0.0001) but favored RTS for flexion (p = 0.02) and external rotation (p = 0.02). Comparisons between hemiarthroplasty and RTS favored RTS for clinical outcomes (p = 0.0001), abduction (p = 0.0001), and flexion (p = 0.0001). Complication rates between groups were not significant for all comparisons. CONCLUSIONS This meta-analysis for surgical treatment of proximal humerus fractures demonstrated that ORIF is superior to hemiarthroplasty, ORIF is comparable to IM nailing, reverse shoulder arthroplasty is superior to hemiarthroplasty but comparable to ORIF with similar clinical outcomes, ROM, and complication rates. However, the study validity is compromised by high risk of bias and low level of certainty. The results should therefore be interpreted with caution. Ultimately, shared decision making should reflect the fracture characteristics, bone quality, individual surgeon's experience, the patient's functional demands, and patient expectations. LEVEL OF EVIDENCE Level III; systematic review and meta-analysis.

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
Hypothesis The purpose of this retrospective study is to investigate the clinical and radiographic outcomes associated with the use of a standard metal plate as an endosteal implant in combination with a lateral locking plate to treat 4 patients with displaced proximal humerus fractures. Methods A retrospective case series study design was utilized, and the medical records of 4 patients with displaced, 3-part proximal humerus fractures treated using this technique between January 2019 and July 2021 were reviewed for this study. The mean age was 52 years (range, 44-57 years). The radiographic outcome of interest was humeral neck-shaft angle preoperatively, intraoperatively, and at the latest follow-up. The average follow-up duration was 62 weeks (range, 12-161 weeks). Results All fractures healed without loss of reduction or neurovascular deficits. Avascular necrosis was not observed in the 2 patients with sufficient follow-up time to make such an evaluation. The average neck-shaft angles preoperatively, intraoperatively, and at the latest follow-up were 104.8°, 139.8°, and 137°, respectively. Conclusion Locking plate technology augmented with an endosteal plate provided stable reduction and restoration of physiologic alignment in a small number of patients with displaced proximal humerus fractures. This construct creates a second column of fixation, providing medial column support, and could be removed in the event of a future revision to a reverse shoulder arthroplasty.

Abstract
Background There has been an increasing amount of interest and research examining best practices for the treatment of proximal humerus fractures (PHF). Recent, high-level randomized control trials and many retrospective cohort studies have failed to demonstrate clear benefit of surgical management for these injuries especially in the elderly (generally defined as ≥65 years old). There is a paucity of research available on outcomes after surgical and nonsurgical treatment of proximal humerus fractures in adults younger than 65 years, and comparative data are almost nonexistent. The purpose of our study was to perform a systematic review and meta-analysis on the available data to determine if the literature supports surgical management over conservative treatment for PHFs in adults younger than 65 years. Materials and methods Adhering to PRISMA guidelines, a systematic review of proximal humerus fractures was performed using MEDLINE and Google Scholar databases. Studies were included if they reported useable data such as outcome measures for adult patients younger than 65 years. Quality of nonrandomized studies was assessed utilizing the MINORs criteria. Extracted data were analyzed using statistical software with P-value set at 0.05. Results Six studies were included in the study for data extraction and statistical analysis. When comparing Constant Scores (CS) and Oxford Shoulder Scores (OSS) of operatively and nonoperatively treated adult patients aged less than 65 years, no statistical differences were found. Furthermore, no statistical differences in CS or OSS were found comparing elderly patients (defined as ≥65 years) and adult patients (defined as 18 to <65 years). Analysis of DASH outcome data did show statistical differences of the three cohorts (nonoperative <65, operative <65, and operative ≥65). Thus, only the limb-specific (not joint specific) outcome score (DASH) was found to be significantly different upon data analysis. Differences in shoulder-specific outcome scores (OSS and CS) failed to meet significance. Conclusion The available literature does not demonstrate a clear clinical benefit of operative treatment over nonoperative management of proximal humeral fractures in adult patients younger than 65 years. These results challenge the widely accepted practice of choosing surgical treatment in adult patients younger than 65 years with PHFs.

Abstract
Proximal humerus fractures are common in elderly patients. Not all patient are fit for major surgery. Percutaneous fixation can be a suitable option though surgeons should be aware of the risks and complications. This case is about a 90-year-old woman with a proximal humerus fracture. After closed anatomical reduction we performed percutaneous K-wire fixation of the humerus fracture with a single K-wire. Five days postoperatively the patient experienced increased pain and dyspnea due to a pneumothorax caused by intrathoracic migration of the K-wire. Percutaneous fixation can be a suitable treatment for low-maintenance and fragile patients but surgeons should act with caution. Multiple threaded K-wires with a bend-free end should be used to reduce the risk for loss of repositioning or migration of the K-wire.

Abstract
PURPOSE There is no consensus in the literature on nonoperative treatment of displaced and multipart fractures of proximal humerus as those are normally treated operatively. Our aim was to compare the functional results of nonoperative management and open reduction internal fixation with the proximal humerus internal locking system of 2-, 3-, and 4-part proximal humerus fractures, among themselves and with a healthy control group. METHODS Between 2014 and 2018, 92 proximal humerus fractures constituting a nonoperative group (n = 47) and an operative group (n = 45) together with healthy control subjects (n = 45) were analyzed in a tertiary care referral center. The American Shoulder and Elbow Surgeons (ASES) shoulder score and visual analog scale (VAS) pain score were used for subjective functional analysis. Range of motion and muscle strength were analyzed objectively for all patients and healthy control subjects. RESULTS In 2-part fractures, VAS scores and hand grip strength were determined as lower in the nonoperative group (p = 0.033 and p = 0.034, respectively). In 3- and 4-part fractures, there was no difference between the two groups in terms of ASES and VAS scores. Patients who underwent surgery had more muscle strength than those in the nonoperative group, but only arm extensor and forearm flexor muscle strengths were statistically significant for 3-part fractures. In cases of 4-part fractures, objective functional results were similar between the two groups. CONCLUSIONS With insufficient functional results and high complication rates in surgery, nonoperative management is still the preferred choice for proximal humerus fractures, especially in case of multipart fractures.

Abstract
AIMS Conservative treatment of moderately displaced proximal humeral head fractures yields good clinical results, but secondary fragment displacement may occur. Identification of those fractures at risk of displacement may influence initial decision-making. METHODS A total of 163 shoulders in 162 patients with conservatively treated isolated proximal humeral fractures were included. The fractures occurred between January 2015 and May 2018. The mean age of the patients was 69 years (26 to 100) and the mean follow-up was 144 days (42 to 779). The fractures were classified according to Neer. Scores for osteoporosis (Tingart, Deltoid Tuberosity Index (DTI)) and osteoarthritis (OA) of the glenohumeral joint were assessed. Translation of the head on follow-up radiographs of more than 10 mm was defined as displacement. Eccentric head index (EHI) describes the offset of the humeral head centre in relation to the diaphyseal axis. The ratio was estimated on anteroposterior (AP) and Neer views. Medial hinge was considered intact if the medial cortex proximal and distal to the fracture was in line on AP view. RESULTS Secondary fracture displacement occurred in 41 patients (25.2%). Clinical risk factors were alcohol abuse (odds ratio (OR) 6.8; 95% confidence interval (CI) 1.3 to 36; p = 0.025) and previously diagnosed osteoporosis (OR 4.6; 95% CI 0.6 to 34; p = 0.136). Age (OR 1.1; 95% CI 1.0 to 1.1; p = 0.003) and sex (OR 0.9; 95% CI 0.3 to 2.8; p = 0.867) were not independent factors. Radiological risk factors were OA grade 3 (OR 16.4; 95% CI 0.25 to 37.6; p = 0.107) and osteoporosis with the DTI (OR 10; 95% CI 0.8 to 250; p = 0.031) being more predictive than the Tingart score (OR 2.3; 95% CI 0.8 to 4.7; p = 0.041). A high EHI (AP/Neer > 0.4, OR 18.9; 95% CI 2.1 to 30.9/3.0; 95% CI 1.1 to 8.0; p = 0.002/p = 0.033) and a disrupted medial hinge (OR 3.7; 95% CI 1.1 to 12.6; p = 0.039) increased the risk of secondary displacement significantly. Neer classification had no influence. CONCLUSION During conservative treatment, a quarter of patients showed secondary fracture displacement of at least 10 mm. Patients with alcohol abuse, severe OA, and osteoporosis are at risk. Newly defined EHI and disrupted medial hinge are relevant predictors for secondary displacement.

Abstract
Proximal humerus fractures (PHF) are common injuries in the elderly population. Conservative treatment is indicated for undisplaced and stable fractures, which account for almost 80% of the cases. More complex fracture patterns might need surgery, with a wide variety of indication criteria and surgical techniques described in the literature. Surgical treatment should be reserved for patients in good clinical conditions, autonomous in daily living activities and able to adhere to postoperative rehabilitation protocols. In the elderly population with severe osteoporosis, cognitive impairment and clinical comorbidities, the risk of surgical failures is high. In these patients, the choice between surgical and conservative treatment, as well as for the type of procedure, is even more difficult, with no general consensus in the literature. Final indication is usually conditioned by surgeon’s experience and preference. Two independent reviewers (B.H and G.G) independently extracted studies on proximal humeral fractures. All selected studies were screened independently (B.H and G.G) based on title and abstract. Then the full text of any article that either judged potentially eligible was acquired and reviewed again. Any disagreement was resolved by discussing the full text manuscripts. Aim of the present paper is to review the literature about indications and results of osteosynthesis for proximal humerus fragility fractures in the elderly population.

Abstract
BACKGROUND To evaluate the effect of intramedullary nail and locking plate in the treatment of proximal humerus fracture (PHF). METHODS China National Knowledge Infrastructure (CNKI), Chinese Scientific Journals Database (VIP), Wan-fang database, Chinese Biomedicine Database (CBM), PubMed, EMBASE, Web of Science, and Cochrane Library were searched until July 2018. The eligible references all show that the control group uses locking plates to treat PHF, while the experimental group uses intramedullary nails to do that. Two reviewers independently retrieved and extracted the data. Reviewer Manager 5.3 was used for statistical analysis. RESULTS Thirty-eight retrospective studies were referred in this study which involves 2699 patients. Meta-analysis results show that the intramedullary nails in the treatment of proximal humeral fractures are superior to locking plates in terms of intraoperative blood loss, operative time, fracture healing time, postoperative complications, and postoperative infection. But there is no significance in constant, neck angle, VAS, external rotation, antexion, intorsion pronation, abduction, NEER, osteonecrosis, additional surgery, impingement syndrome, delayed union, screw penetration, and screw back-out. CONCLUSIONS The intramedullary nail is superior to locking plate in reducing the total complication, intraoperative blood loss, operative time, postoperative fracture healing time and postoperative humeral head necrosis rate of PHF. Due to the limitations in this meta-analysis, more large-scale, multicenter, and rigorous designed RCTs should be conducted to confirm our findings. TRIAL REGISTRATION PROSPERO CRD42019120508.

Abstract
This systematic review of overlapping meta-analyses was conducted to propose a principle to make decisions for comparing clinical safety and efficacy of surgical and non-surgical treatment for displaced 3-part and 4-part fractures of the proximal humerus. Three electronic databases (PubMed, EMBASE, and the Cochrane Library) were systematically searched to retrieve available published systematic reviews and meta-analyses comparing surgical versus non-surgical treatment for displaced 3-part and 4-part fractures of the proximal humerus. Ten meta-analyses were identified for this investigation. Based on the application of selection with the Jadad algorithm, a meta-analysis including 6 randomized clinical trials was selected for this systematic review, which demonstrated the best available evidence that no statistically significant differences were found in the Constant score, health-related quality of life, and mortality between surgical and non-surgical treatments for displaced 3-part and 4-part fractures of the proximal humerus; however, surgical treatment was associated with a significant increase in the incidence of reoperation. This systematic review of overlapping meta-analyses reveals that although surgical treatment is more advantageous than and superior to non-surgical treatment for displaced 3-part and 4-part fractures of the proximal humerus, the former leads to a higher incidence of postoperative complications.

Abstract
Background Proximal humeral fractures (PHFs) are the third most common fracture in older patients. The purpose of the study was to prospectively evaluate the outcomes of PHF fixation with a locking blade nail (LBN) or locking plate (PHILOS) osteosynthesis in a homogeneous elderly patient population. Methods Inclusion criteria were an age > 60 years and the capacity to give informed consent. Patients with isolated tuberosity fractures, previous trauma or surgery, advanced osteoarthritis, fracture dislocation, pathological fractures, open fractures, neurological disorders, full-thickness rotator cuff tears, fracture line at the nail entry point or severely reduced bone quality intra-operatively were excluded. Eighty one patients with PHFs were randomised to treatment using LBN or PHILOS. Outcome measures comprised Constant score, age and gender adjusted Constant score, DASH score, VAS for pain, subjective overall condition of the shoulder (1–6) and active shoulder range-of-motion in flexion and abduction. Plain radiographs were obtained in two planes. All data were collected by an independent observer at 3, 6 and 12 months postoperatively. Results Thirteen patients were excluded intra-operatively due to rotator cuff tears, fracture morphology or poor bone-quality. Of the remaining 68 patients, 27 in the LBN and 28 in the PHILOS group completed the full follow-up. Mean age at surgery was 75.6 years and the majority of PHFs were three-part fractures (49 patients). Baseline demographics between groups were comparable. All outcome measures improved between assessments (p < 0.001). The LBN group showed improved DASH scores as compared to PHILOS at 12 months (p = 0.042) with fewer incidences of secondary loss of reduction and screw cut-out (p = 0.039). A total of 29 complications (in 23 patients) were recorded, 13 complications (in 12 patients) in the LBN group and 16 complications (in 11 patients) in the PHILOS group (p = 0.941). No significant inter-group difference was observed for any other outcome measures, nor was fracture morphology seen to be associated with clinical outcome or complication rate. Conclusions At short-term follow-up, LBN osteosynthesis yielded similar outcomes and complication rates to PHILOS plate fracture fixation in an elderly patient population, though with a significantly lower rate of secondary loss of reduction and screw cut-out.

Abstract
Fractures of the proximal humerus are a very common presentation in modern Trauma and Orthopaedic practice. In an ever-aging population, the incidence has dramatically increased resulting in a large socioeconomical burden. The surgical management of these injuries has evolved over the years. Patient outcomes are variable and there is no consensus on treatment approach. This review article focuses on the outcomes following fracture fixation using common surgical techniques.

Does an early mobilization and immediate home-based self-therapy exercise program displace proximal humeral fractures in conservative treatment? Observational study. J Shoulder Elbow Surg 2018; 27:2021-2029.

Abstract
BACKGROUND Nonoperative management of proximal humeral fractures (PHFs) is the most common treatment, but its functional outcome may improve with early mobilization. In frail osteoporotic patients, quick recovery of prefracture independency is mandatory. This study assessed fracture displacement in PHFs managed with conservative treatment after early mobilization and a home-based self-exercise program. METHODS We retrospectively analyzed the radiologic displacement of fracture fragments of PHFs treated conservatively with early mobilization and a home-based self-exercise program. RESULTS Included were 99 patients with 26 one-part, 32 two-part, 32 three-part, and 9 four-part PHFs managed conservatively, followed by early mobilization and a home-based self-exercise program. In the x-ray examinations, the head displaced from varus into valgus 55° ± 23° to 42° ± 22°, in the normal range of anatomic values. The medial hinge displaced from medial to the diaphysis (+1 ± 6 mm) to lateral to the head (-0.6 ± 6 mm). The greater tuberosity displaced cranially from -1 ± 7 mm to 2 ± 5 mm. The Constant score at the 1-year follow-up was 79.69 ± 16.3. DISCUSSION AND CONCLUSIONS The home-based self-exercise program for conservative treatment of PHFs displaces the head-diaphysis angle and the medial hinge toward anatomic reduction, but there is a risk of greater tuberosity cranial displacement. Functional results are fairly good, allowing frail patients to keep on with their independency and life style. Because a large number of patients might need further physiotherapy, the quality of the home-based self-exercises should be supervised.

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
Introduction: Proximal humerus fractures are common in the elderly. The evaluation and management of these injuries is often controversial. The purpose of this study is to review recent evidence and provide updated recommendations for treating proximal humerus fractures in the elderly. Methods: A literature review of peer-reviewed publications related to the evaluation and management of proximal humerus fractures in the elderly was performed. There was a focus on randomized controlled trials and systematic reviews published within the last 5 years. Results: The incidence of proximal humerus fractures is increasing. It is a common osteoporotic fracture. Bone density is a predictor of reduction quality and can be readily assessed with anteroposterior views of the shoulder. Social independence is a predictor of outcome, whereas age is not. Many fractures are minimally displaced and respond acceptably to nonoperative management. Displaced and severe fractures are most frequently treated operatively with intramedullary nails, locking plates, percutaneous techniques, or arthroplasty. Discussion: Evidence from randomized controlled trials and systematic reviews is insufficient to recommend a treatment; however, most techniques have acceptable or good outcomes. Evaluation should include an assessment of the patient’s bone quality, social independence, and surgical risk factors. With internal fixation, special attention should be paid to medial comminution, varus angulation, and restoration of the calcar. With arthroplasty, attention should be paid to anatomic restoration of the tuberosities and proper placement of the prosthesis. Conclusion: A majority of minimally displaced fractures can be treated conservatively with early physical therapy. Treatment for displaced fractures should consider the patient’s level of independence, bone quality, and surgical risk factors. Fixation with percutaneous techniques, intramedullary nails, locking plates, and arthroplasty are all acceptable treatment options. There is no clear evidence-based treatment of choice, and the surgeon should consider their comfort level with various procedures during the decision-making process.

Abstract
BACKGROUND Fractures of the proximal humerus are common and most often treated non-operatively. However, long-term follow-up studies focusing on functional results and quality of life in patients after this type of fracture are scarce. The primary aim of this study is to report the long-term functional and quality of life outcome in patients with a proximal humeral fracture. MATERIALS AND METHODS A retrospective analysis of all consecutive patients undergoing non-operative treatment for a proximal humeral fracture in a level 2 trauma centre between January 2000 and December 2013 was performed. A database consisting of all relevant demographic, patient and fracture characteristics was created. Subsequently, a questionnaire containing the DASH (Disabilities of the Arm, Shoulder and Hand) score, EuroQol-5D (EQ-5D), VAS (visual analogue scale) score, and subjective questions was sent to all patients. RESULTS A total of 410 patients (65 male, 345 female) were included for analyses. Average follow-up was 90 ± 48 months. DASH-scores <15 were considered as good. A median DASH-score of 6.67 [0.83-22.50] was found. A significant lower DASH-score was seen in patients under the age of 65 compared to older patients (p < 0.001). In comparison to an age-matched general Dutch population, Health related Quality of Life (HrQoL) on the EQ-us was not significantly worse in our study population (difference 0.02). Strong (negative) correlation was found between DASH-score and VAS-score, and DASH-score and HrQoL, respectively ρ = -0.534 and ρ = -0.787. CONCLUSION Long-term functional and quality of life outcomes are good in most patients after proximal humeral fractures, but negatively correlated to each other. LEVEL OF EVIDENCE Level III.

Abstract
Purpose The incidence of proximal humeral fractures is high in the elderly, and the superior management of these fractures remains a controversy. The study aims to compare clinical outcomes of intramedullary nails, locking plates and conservative treatment for the management of displaced proximal humeral fractures in the elderly. Patients and methods In this prospective study, a total of 198 patients with 2- or 3-part proximal humeral fractures who received fixation of locking plates or intramedullary nails or conservative treatment were included. The primary outcome was the 24-month Constant-Murley score. The secondary outcomes included the American Shoulder and Elbow Surgeons (ASES) scores, the visual analog scale (VAS) pain scores, shoulder range of motion and complication rate. Results There were no statistically significant differences in the Constant-Murley scores and ASES scores among the plate group, the nail group and the conservative group for 2-part fractures. For 3-part fractures, Constant-Murley scores and ASES scores were lower in the conservative group compared with those in the plate group and the nail group. Besides, the conservative group showed a significantly lower external rotation during follow-ups. The complication rate was comparable among the plate group, the nail group and the conservative group for both 2-part and 3-part fractures. Conclusion Similar satisfactory functional outcomes can be achieved with the locking plates, intramedullary nails or conservative treatment for 2-part proximal humeral fractures in the elderly. The advantages in functional outcomes favor locking plates and intramedullary nails in the management of 3-part proximal humeral fractures.

Abstract
PURPOSE To compare the clinical outcome and complications of locking plates versus intramedullary nails in patients with displaced proximal humeral fractures. Our hypothesis was that there would be no difference between these two implants with regard to clinical outcome and complications. METHODS We performed a systemic review of PubMed, EMBASE, Clinical Trials Registry, Cochrane Central Register of Controlled Trials and Google Scholar to identify all relevant randomized controlled trials, prospective and retrospective comparative studies on April 26, 2017. The studies of locking plates compared to intramedullary nails in patients with displaced proximal humeral fractures were included. We conducted a meta-analysis of shoulder functional scores, range of motion, pain scores, and complications. RESULTS This meta-analysis included 13 comparative studies with 958 patients (529 in the locking plate group and 429 in the intramedullary nail group). A significantly greater external rotation (MD = 9.67; 95% CI, 4.22-15.12; P = 0.0005) and a significantly higher penetration rate (RR = 1.75; 95% CI, 1.11-2.77; P = 0.02) were observed in the locking plate group compared with the intramedullary nail group. Constant-Murley scores, DASH scores and total complication rate were comparable between the two groups. Moreover, there were no significant differences in forward elevation, VAS scores, and other complications. CONCLUSIONS Current evidence indicates that locking plates and intramedullary nails have similar performance in terms of the functional scores and total complication rate. No superior treatment was suggested between locking plates and intramedullary nails for displaced proximal humeral fractures.

The Applications of Finite Element Analysis in Proximal Humeral Fractures. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2017; 2017:4879836. [PMID: 29081829 PMCID: PMC5610852 DOI: 10.1155/2017/4879836] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/06/2017] [Accepted: 08/06/2017] [Indexed: 12/18/2022]
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
BACKGROUND The fractures of proximal humerus have a high incidence in elderly patients, especially 3- or 4-part fracture. There are 4 main treatments including nonoperation, open reduction and internal fixation(ORIF), hemiarthroplasty(HA) and reverse shoulder arthroplasty(RSA). However, which one is the optimal choice remains a controversial topic. METHODS Through the search of three electronic databases (PubMed, Embase, and Cochrane), the randomized controlled trials of 3- or 4-part proximal humeral fracture, until the end of July 2017, which is concerned with the elderly patients, were identified. The quality evaluation of each study was evaluated, Constant score and reoperation rates were extracted and analyzed. We used R(R i386 3.3.2) and the package of gemtc to perform our network meta-analysis. RESULTS Seven randomized controlled experiments with a total number of 347 patients were brought into our network meta-analysis. The rank probability plot of Constant score showed that the RSA had significantly the highest Constant score and lower reoperation than other treatments. The other way around, the efficacy of ORIF was the poorest. The rank for the Constant score was: RSA, HA, nonoperation and ORIF. The rank for the reduction in total reoperation rates was: RSA, nonoperation, HA and ORIF. CONCLUSIONS The statistical result suggested that RSA has become a beneficial choice to treat displaced 3-or 4-part fracture in elderly patients, that might result in more favorable clinical outcomes and reduction of reoperation rates than other methods performed for the same indication. But the ORIF is the worst.

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
BACKGROUND Little is known about non-operative treatment of proximal humerus 4-part and severe displaced fractures as those are normally treated operatively. In this study, we present a historical collective of two level I trauma centers, where all humeral head fractures, despite displaced fractures, received non-operative treatment within a 10 years period. Functional and clinical results of 2-, 3- and 4-part fractures were compared to those after fixed angle intramedullary nailing by matched pair analysis. METHODS Between 2000 and 2010, 167 patients with 2-, 3- and 4-part humeral head fractures were treated non-operatively in two level I trauma centers in Rostock. Complete clinical, functional and radiographic follow-up were available for 41 patients in the retrospective analysis. The results were compared by matched-pair analysis to a prospective series of 143 patients treated by antegrade intramedullary nailing using a proximal humeral nail. Of these 143 patients complete radiological and clinical 12 months' follow-up was available for 117 patients. Thus, it was possible to built 41 pairs according to age, gender, and fracture type. Statistical significant differences in constant score (CS), pain, activity of daily living (ADL), range of motion (ROM) and muscle strength were evaluated by Wilcoxon test. Furthermore, x-ray analysis of fracture healing and complications were recorded. RESULTS Operative treatment was not superior to non operative treatment concerning functional results, even in displaced fractures. The only significant difference was found in 3-part-fractures, where better ROM was reached in the non-operative group (p = 0.05). In contrast, there was a tendency toward better activity of daily living (ADL) in intramedullary nailing, but this did not reach statistical significance. X-ray findings revealed better anatomical reconstruction with less valgus and varus displacements after surgery (15% versus 50%, p < 0.005). The complication rate of 37% was higher in the surgery group with a reoperation rate of 32%. CONCLUSION In our study, surgical treatment by fixed angle intramedullary nailing (Targon PH) seems not to be superior to non-operative treatment, regardless of fracture type. In 2-, 3- and 4-part fractures functional and clinical results were similar.

Abstract
INTRODUCTION Proximal humeral fractures with a spiral line of fracture extending from the humeral head to the diaphyseal region are increasing. Treatment for these fractures is comparable to that for shaft fractures. The purpose of this study was to evaluate the use of a new "Long" humeral nail for this type of lesion and identify the best distal locking. MATERIALS AND METHODS Forty-three patients treated with a Long Diphos Nail® were selected for this study: main exclusion criteria were poor cognitive and responsive ability to physical therapy, four-part fracture requiring humeral head replacement, an isolated greater or lesser tubercle fracture and a head-splitting fracture. All patients were divided into two groups according to the distal locking (single or double) and clinically evaluated at 1, 3, 6 and 12 months after surgery. The following parameters were evaluated: fracture healing on radiographic images every month; level of pain with Visual Analogue Scale (VAS); recovery of shoulder function or ability to resume normal daily activities according to the Constant Scoring System (CSS); patient satisfaction; and complications, like fracture consolidation defect or delay. A statistical analysis was performed. RESULTS Improvements in pain, satisfaction and shoulder functional recovery were recorded. Patients reached fracture healing in two to six months. The mean healing time was better for double distal locking (p=0.04).There was a clinically greater difference (p=0.006) between the groups for the mean Constant score at 3 months follow-up, with better results for the double distal locking group. Complications were: one patient with a consolidation delay with a single distal locking screw breakage; it was necessary to remove the nail and perform a second treatment. CONCLUSIONS The results of the study indicate the efficacy of Long Diphos Nail® in the treatment of fractures with a line of fracture extending to the proximal diaphyseal region. The features of a multiplane stabilisation above the fracture and a distal double locking may represent the key for a good fixation for 11-A2, A3 or B2 fractures with a long spiral line. A double distal locking reduces fracture micro-instability and so patients recover function and strength quicker because of less pain at the fracture site.

Abstract
Necrosis of the humeral head, infections and non-unions are among the most dangerous and difficult-to-treat complications of proximal humeral fractures. The aim of this work was to analyse in detail non-unions and post-traumatic bone defects and to suggest an algorithm of care. Treatment options are based not only on the radiological frame, but also according to a detailed analysis of the patient, who is classified using a risk factor analysis. This method enables the surgeon to choose the most suitable treatment for the patient, thereby facilitating return of function in the shortest possible time. The treatment of such serious complications requires the surgeon to be knowledgeable about the following possible solutions: increased mechanical stability; biological stimulation; and reconstructive techniques in two steps, with application of biotechnologies and prosthetic substitution.

Abstract
INTRODUCTION The objectives of this study were to describe the surgical technique of fixation of 3-4 part proximal humeral fractures with polyaxial locking plates utilising a minimally invasive approach and to evaluate the accuracy of reduction and stability of fixation. PATIENTS AND METHODS We retrospectively reviewed 90 patients. Fractures were classified according to the Neer classification system. Different radiological parameters were measured to assess the quality of reduction and the stability of fixation. Complications and clinical outcomes were evaluated after one year of minimum follow up. RESULTS There were 76 women and 14 men, with a mean age of 67.4years ±13 (range, 29-85). There were 60 3-part and 30 4-part fractures. Frozen cancellous allograft was used in 30 cases (33.3%). All fractures progressed to union and at one year follow up, the mean Constant score was 79.6±12(range, 62-100). Mean forward flexion, abduction, external rotation and internal rotation were 155°, 148°, 39° and vertebra Dorsal 8, respectively. Complications were noted in seven patients while the postoperative "head-diaphysis angle", "greater tuberosity height" and "medial metaphysis reconstruction" were close to the anatomical parameters; no significant differences were noted at one year radiological follow up. CONCLUSION Reliable and stable fixation can be expected with the use of polyaxial locking plate through a minimally invasive approach for the treatment of 3-4 part proximal humeral fractures. Satisfactory functional results for this procedure can be obtained.

Abstract
AIM The aim of this study was to evaluate risk factors for the development of humeral head necrosis and non-union after proximal humeral fractures-in particular, general risk factors that exist independent of fracture type. MATERIALS AND METHODS This study included patients (n=154) treated for proximal humeral fracture by means of open reduction and internal fixation (ORIF) using the Philos plate at a single level I trauma centre between January 2005 and December 2013. Follow-up monitoring included radiographic examination before hospital discharge, and again at 6 weeks, 12 weeks, and 6 months after surgery. At a minimum follow-up time of 6 months, radiographs taken in the anteroposterior and axial projection were evaluated in regard to the development of humeral head necrosis, non-union, and secondary screw cut out. RESULTS A total of 154 patients (61 males, 93 females) were available for radiological checkup. Mean age was 55.8 years (range: 19-91 years). There were statistically significant correlations between the development of avascular necrosis (AVN) and fracture type, non-union and smoking, and screw cut out - as well as overall complication rate - and age. The time to surgery did not influence the risk for AVN or non-union, independent of fracture type. In this study population, the risk of developing non-union after ORIF was 3.9-fold higher in heavy smokers (i.e., >20 cigarettes per day). The risk for screw cut out was 4.1-fold higher in patients over 60 years of age, and the overall risk for complications was 3.3-fold higher. CONCLUSION The older the patient, the more carefully one must consider the decision between conservative and operative treatments. If surgical treatment is performed, screw length should be selected depending on the patient's age. Heavy smokers must be informed preoperatively of the increased risk for bony non-union after ORIF.
