ABSTRACT

CASE: (1) A 69-year-old man sustained a proximal humeral fracture-dislocation. During emergency surgery, copious bleeding occurred. A pseudoaneurysm was identified 30 days postoperatively. (2) A 69-year-old man sustained a proximal humeral fracture and axillary artery injury. Physical examination demonstrated a cold but pink hand. Hemiarthroplasty and bypass vein grafting were performed. (3) An 86-year-old woman sustained a proximal humeral fracture and axillary artery injury. Her hand had turned cold and pale. Reverse shoulder arthroplasty and bypass vein grafting were performed. CONCLUSION: In cases of proximal humeral fractures with significant displacement, concomitant axillary artery injury must be assessed and if there is a high index of suspicion, prompt advanced imaging is necessary.

ABSTRACT

Background: This study evaluated national trends in cemented and uncemented reverse shoulder arthroplasty (RSA) for proximal humerus fractures using a comprehensive national surgical database. This study aimed to compare RSA used in the treatment of proximal humerus fractures with the literature and to determine the country's trend. Methods: A cross-sectional study was conducted using the health records of individuals aged ≥ 18 years who underwent RSA for proximal humerus fractures between 2016 and 2022. Patients were divided into cemented and uncemented groups, and demographic data (age, sex), duration of hospital stay, transfusions, revisions, mortality, and Charlson Comorbidity Index (CCI) scores were analyzed. Results: A total of 618 cemented RSA and 1,364 uncemented RSA procedures were reviewed. Patients who underwent cemented RSA were significantly older than those who had uncemented RSA (p = 0.002). Transfusion rates were higher in the cemented RSA group (p = 0.006). The frequency of revision surgery was 6.1%. Younger age and male sex were associated with revision (p < 0.001). CCI scores were higher among transfused patients than non-transfused patients (p < 0.001). The incidence of cemented RSA was 11.7% and 49% in 2016 and 2022, respectively. Differences were found among hospital types and geographical regions. Conclusions: While cemented RSA has been gaining attention and increased application in recent years for proximal humerus fractures, uncemented RSA still predominates. The choice between these 2 methods is largely influenced by regional and hospital-level factors. The type of RSA and high CCI scores were found to have no significant impact on the risk of surgical revision.

ABSTRACT

BACKGROUND: Imaging techniques such as X-rays and 3D Computed Tomography (CT) are used to diagnose and evaluate a patient's shoulder before and after surgery. Identifying the kind, location, and severity of a shoulder fracture helps surgeons choose the right treatment and surgery. OBJECTIVES: The study examines the effectiveness of small incision reduction and superior closure pinning in treating Ideberg type III glenoid fractures identified by X-ray and CT scans. MATERIALS AND METHODS: From October 2017 to June 2022, 40 patients with Ideberg type III glenoid fractures underwent mini-incision reduction and superior closed pinning fixation using the Anterior (AA) and Posterior (PA) approaches. Pre- and post-surgery shoulder scores and imaging data were analyzed. Outpatient review and shoulder anteroposterior radiographs were collected at 1, 3, 6, and 12 months after surgery. We assessed shoulder joint function using the American Shoulder and Elbow Society (ASES) shoulder score, VAS score, Constant-Murley Shoulder Outcome (Constant) score, and DASH score. RESULTS: A total of 40 patients were monitored for 14-16 months, averaging 15.2 ± 0.3 months. All fractures were healed between 14-25 weeks from X-rays, averaging 17.6 ± 5.4 weeks. Both the AA and PA groups had similar shoulder score changes. However, the AA group did better. In all cases, ASES shoulder scores were outstanding at 80%. Radiographs demonstratedno traumatic arthritis or internal fixation failure consequences like screw loosening or breakage. CONCLUSION: It was concluded that Ideberg type III glenoid fracture reduction with an anterior small incision and superior closed pinning hollow lag screw internal fixation could be successful.

ABSTRACT

BACKGROUND: Open reduction and internal fixation (ORIF) using locking plates is a widely adopted treatment for displaced proximal humerus fractures. Various augmentation techniques have been developed to enhance the stability of plate fixation. Among these, iliac bone autograft is notable for its advantages over allografts, such as ready availability and the elimination of costs and risks associated with disease transmission. Despite its potential benefits, data on the outcomes of iliac bone autograft augmentation (IBAA) are still limited. This study aims to present the mid- to long-term results of treating proximal humerus fractures with ORIF using locking plates and IBAA. METHODS: The study included 15 patients treated with ORIF and IBAA. We classified fracture patterns using the Neer classification and estimated local bone density via the deltoid tuberosity index. We measured the neck shaft angle (NSA) and humeral head height (HHH) on both immediate postoperative and most recent X-ray images to assess the maintenance of reduction. Clinical outcomes were evaluated using the DASH (Disabilities of the Arm, Shoulder, and Hand) and Constant scores. RESULTS: The average follow-up duration was 59.56 months, ranging from 24 to 93 months. A majority of fractures were classified as four-part (53%). The average immediate and late postoperative NSAs were 132.6±8.19 and 131.6±7.32 degrees, respectively. The average HHH on the immediate postoperative and latest follow-up images were 16.46±6.07 and 15.10±5.34, respectively. None of the patients exhibited any radiological signs of avascular necrosis or loss of reduction at the latest follow-up. The mean postoperative Constant and DASH scores at the latest follow-up were 79.6 and 11.5, respectively. CONCLUSION: Our findings suggest that ORIF with IBAA is an effective method for managing three- or four-part proximal humerus fractures, yielding excellent outcomes.

ABSTRACT

BACKGROUND: The calcar of the proximal humerus is a fundamental structure for medial humeral column support. This study aimed to assess the outcome of osteosynthesis across cases of unstable proximal humerus fractures (PHFs) with medial calcar comminution, following treatment with a PHILOS locking plate and medial support screw (MSS). METHODS: Between January 2010 and December 2018, we retrospectively analyzed the outcomes of 121 cases of osteosynthesis for PHFs with medial column disruption. For the medial support, at least one oblique screw was inserted within 5 mm of the subchondral bone in the inferomedial quadrant of the humeral head. All patients were categorized into two groups: 26 patients in the single MSS group, and 95 in the multiple MSS group. Follow-up after at least an year involved clinical and radiographic outcome evaluations, and correspondingly measuring the Constant-Murley score, University of California, Los Angeles (UCLA) shoulder scale, pain visual analogue scale (VAS), major complications, neck-shaft angle (NSA), humeral head height (HHH), and the eventual time to bone union. Risk factors for the major complications were assessed by multivariate logistic regression analyses. RESULTS: The cohort's mean age was 64.4 ± 15.4 years, and the mean follow-up duration was 19.5 ± 7.6 months. At the final follow-up, between the single MSS and multiple MSS groups, no significant differences in the Constant-Murley score (p = 0.367), UCLA score (p = 0.558), VAS (p = 0.571), time to bone union (p = 0.621), NSA loss (p = 0.424), and HHH loss (p = 0.364) were observed. The incidence of complications (p = 0.446) based on the number of MSS were not significantly different. The initial insufficient reduction after surgery (of NSA < 125°) was found to be a significant risk factor for post-surgical complications. CONCLUSIONS: To treat unstable PHFs, the use of at least one MSS along with a locking plate system is sufficient to achieve satisfactory outcomes. Successful operative treatment using a locking plate for PHF treatment is inherent in anatomical fracture reduction, coupled with medial column support.

ABSTRACT

Aims: Vascular compromise due to arterial injury is a rare but serious complication of a proximal humeral fracture. The aims of this study were to report its incidence in a large urban population, and to identify clinical and radiological factors which are associated with this complication. We also evaluated the results of the use of our protocol for the management of these injuries. Methods: A total of 3,497 adult patients with a proximal humeral fracture were managed between January 2015 and December 2022 in a single tertiary trauma centre. Their mean age was 66.7 years (18 to 103) and 2,510 (72%) were female. We compared the demographic data, clinical features, and configuration of those whose fracture was complicated by vascular compromise with those of the remaining patients. The incidence of vascular compromise was calculated from national population data, and predictive factors for its occurrence were investigated using univariate analysis. Results: A total of 18 patients (0.5%) had a proximal humeral fracture and clinical evidence of vascular compromise, giving an annual incidence of 0.29 per 100,000 of the population. Their mean age was 68.7 years (45 to 92) and ten (56%) were female. Evidence of a mixed pattern neurological deficit (brachial plexus palsy) (odds ratio (OR) 380.6 (95% CI 85.9 to 1,685.8); p < 0.001), complete separation of the proximal shaft from the humeral head with medial displacement (OR 39.5 (95% CI 14.0 to 111.8); p < 0.001), and a fracture-dislocation (OR 5.0 (95% CI 1.6 to 15.3); p = 0.015) were all associated with an increased risk of associated vascular compromise. A policy of reduction and fixation of the fracture prior to vascular surgical intervention had favourable outcomes without vascular sequelae. Conclusion: The classic signs of distal ischaemia are often absent in patients with proximal injuries to major vessels. We were able to identify specific clinical and radiological 'red flags' which, particularly when present in combination, should increase the suspicion of a fracture with an associated vascular injury, and facilitate early diagnosis and appropriate combined orthopaedic and vascular intervention.

ABSTRACT

BACKGROUND: The treatment of the displaced proximal humerus fractures (PHF) still facing a lot of unsolved problems. The aim of this study was to evaluate the clinical effect of MultiLoc nails for the treatment of PHF and present outcomes of patients with different Neer's classification and reduction quality. METHODS: Adult patients with PHFs were recruited and treated with MultiLoc nail. Intraoperative data, radiographic and functional outcomes, as well as occurrence of postoperative complications were assessed. RESULTS: 48 patients met inclusion and exclusion criteria and were included in this study. The DASH Score were 32.2 ± 3.1 points at 12 months, and 37.3 ± 2.5 points at the final follow-up. The mean ASES score at 12 months and final follow-up were 74.4 ± 6.2 and 78.8 ± 5.1, respectively. The mean CM Score in all 48 patients reached 68 ± 6.4 points at the final follow-up, relative side related CM Score 75.2 ± 7.7% of contralateral extremity. The incidence rate of complications was 20.8%. Patients with fracture mal-union, adhesive capsulitis were observed but no secondary surgeries were performed. There was no significantly difference of DASH Score 12 months after surgery and at the last follow-up among patients with different Neer's classification or reduction quality. However, functional outcomes such as ASES score and CM score were significantly influenced by severity of fracture and the quality of fracture reduction. CONCLUSIONS: Our study demonstrated that MultiLoc nails is well suited for proximal humeral fractures, with satisfactory health status recovery, good radiographic results, positive clinical outcomes and low rates of complications. The treatment for four part PHF still faces great challenges. Accurate fracture reduction was an important factor for good functional result.

ABSTRACT

PURPOSE: Few studies have focused on the risk factors leading to postoperative blood transfusion after open reduction and internal fixation (ORIF) of proximal humeral fractures (PHFs) in the elderly. Therefore, we designed this study to explore potential risk factors of blood transfusion after ORIF for PHFs. We have also established a nomogram model to integrate and quantify our research results and give feedback. METHODS: In this study, we retrospectively analyzed the clinical data of elderly PHF patients undergoing ORIF from January 2020 to December 2021. We have established a multivariate regression model and nomograph. The prediction performance and consistency of the model were evaluated by the consistency coefficient and calibration curve, respectively. RESULTS: 162 patients met our inclusion criteria and were included in the final study. The following factors are related to the increased risk of transfusion after ORIF: time to surgery, fibrinogen levels, intraoperative blood loss, and surgical duration. CONCLUSIONS: Our patient-specific transfusion risk calculator uses a robust multivariable model to predict transfusion risk.The resulting nomogram can be used as a screening tool to identify patients with high transfusion risk and provide necessary interventions for these patients (such as preoperative red blood cell mobilization, intraoperative autologous blood transfusion, etc.).

ABSTRACT

BACKGROUND: The osteonecrosis ratio in valgus impacted fractures of the proximal humerus is low (<10 %), giving osteosynthesis all its meaning. However, the optimal fixation technique remains controversial. After recentering the humeral head, osteosuture is stable enough to allow bone healing in an adequate position as well as a good long-term shoulder functionality. METHODS: Our cohort included 22 patients with a mean age of 65 (28-83). Patients were placed in a beach-chair position. Surgical exposure was done through an anterolateral, transdeltoid approach. Stay sutures were placed on both tuberosities. Elevation of the humeral head was obtained for 9 patients using iliac crest bone graft, for 7 patients using bone substitutes, for 6 without any graft needed. Both tuberosities were approximated and tied together using two horizontal non-absorbable double-threaded sutures. The whole head was also tied to the humeral metaphysis by cerclage wiring using the same suture. Patients were immobilized in a sling for 4 weeks with no passive or active mobilization; then began rehabilitation starting with passive and active-assisted mobilization. Functional outcome was assessed with the Constant score. Radiographic follow-up was used for fracture healing and osteonecrosis signs. RESULTS: All fractures united within the first 3 months. One patient had radiographic signs of osteonecrosis and one had a secondary displaced fracture without osteonecrosis. At an average follow-up of 35 months, the median Constant score was 83.7 % (63-100) in comparison to the uninjured side. DISCUSSION: A preserved posteromedial periosteal hinge in a valgus impacted fracture of the proximal humerus is key to the success of osteosuture. This hinge provides mechanical stability to the humeral head once elevated, as well as blood-supply from the branches of the posterior circumflex humeral artery. Computed Tomography with Three-Dimensional reconstructed images allow for a precise analysis of this hinge as well as the vascularity of the humeral head. Osteosuture being a minimally invasive surgical procedure plays a predominant role in sparing the remaining vascularization of the humeral head. CONCLUSION: Osteosuture in four-part valgus impacted fractures of the proximal humerus is a minimally invasive procedure as well as a reliable technique yielding good long-term results.

ABSTRACT

CONTEXT: Minimally invasive (MI) approaches are purported to present advantages for osteosynthesis when compared with conventional approaches. This study aimed to compare the medium-term clinical and radiological outcomes of patients with proximal humerus fractures treated by plate osteosynthesis with conventional and MI superolateral approaches. METHOD: The study carried out was a retrospective monocentric comparative analysis. Forty-three cases were followed up - 18 were treated with an MI approach and 25 with a conventional approach. Constant-Murley, DASH and SSV scores were established and standard complications were investigated. RESULTS: No significant differences in functional scores or complications were found between the 2 groups. The only significant difference was for pain which was significantly lower for the MI group. The overall revision rate was 18.3 %. The mean adjusted Constant-Murley for the entire population was 80.1 ± 20.2; the mean DASH score was 17.8 ± 15.9 and the mean SSV was 73.2 ± 19.5. CONCLUSION: This study did not demonstrate any significant differences between the 2 approaches. Given the low patient population in our series, the superiority of the MI approach - as indicated in the literature - was not proven.

ABSTRACT

Greater tuberosity fractures of the humerus can be challenging to manage due to their complex anatomy and the potential for compromised shoulder function. We present a novel technique for treating greater tuberosity fractures utilizing specialized anatomical plates and rotator cuff reinforcement. The technique involves the use of an anatomically T-shaped plate designed specifically for the greater tuberosity region of the humerus, allowing for precise fixation and stability. Additionally, rotator cuff reinforcement is performed using sutures to enhance structural integrity and promote early mobilization. The simplified process is as follows: After administering anesthesia, a 3 cm incision is made along the lateral aspect of the shoulder to precisely expose the fracture site of the greater tuberosity. A suture of size 5 is skillfully threaded through the tough rotator cuff tendon to securely attach the proximal humerus to the anatomical plate after the greater tuberosity has been reduced. Intraoperative fluoroscopy is utilized to verify the accurate positioning of plates and screws. After ensuring everything is correct, the surgery concludes.

ABSTRACT

BACKGROUND: Most studies infer increasing incidence of proximal humeral fractures (PHF) from the 1950´s until the 1990´s. Recent time trends are less clear. OBJECTIVES: Our primary objective was to identify time trends in the age- and sex-adjusted adult incidence of PHF in Malmö, Sweden, from year 1944 until 2020. Our secondary objectives were to describe the variation in incidence according to age, the monthly distribution, and to compare data from the two most recent decades with earlier. STUDY DESIGN AND METHODS: Malmö has one emergency hospital where acute fractures are treated. We identified PHF in adult patients (≥ 18 years) by reviewing relevant radiology examinations during 17 sample years from year 1944 to 2020. We used jointpoint analyses to estimate time trends. RESULTS: We identified 3 031 PHF during the study period (3 231 161 person years), 73% were sustained by women with mean age of 69 years (mean age in men 59). Joinpoint analyses indicated an increase in the age- and sex-adjusted incidence of PHF from year 1944 (52 per 100 000 person years) until 1977 (120 per 100 000) and thereafter a decrease until 2020 (85 per 100 000). A seasonal variation with more fractures during winter months, was apparent in earlier but not recent decades. CONCLUSIONS: The age- and sex-adjusted incidence of PHF increased in Malmö, Sweden, from the 1940´s until year 1977 and thereafter decreased until 2020. More fractures were seen during winter months in earlier but not recent decades.

ABSTRACT

Aims: Proximal humeral fractures are the third most common fracture among the elderly. Complications associated with fixation include screw perforation, varus collapse, and avascular necrosis of the humeral head. To address these challenges, various augmentation techniques to increase medial column support have been developed. There are currently no recent studies that definitively establish the superiority of augmented fixation over non-augmented implants in the surgical treatment of proximal humeral fractures. The aim of this systematic review and meta-analysis was to compare the outcomes of patients who underwent locking-plate fixation with cement augmentation or bone-graft augmentation versus those who underwent locking-plate fixation without augmentation for proximal humeral fractures. Methods: The search was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Articles involving patients with complex proximal humeral fractures treated using open reduction with locking-plate fixation, with or without augmentation, were considered. A meta-analysis of comparative studies comparing locking-plate fixation with cement augmentation or with bone-graft augmentation versus locking-plate fixation without augmentation was performed. Results: A total of 19 studies were included in the qualitative synthesis, and six comparative studies were included in the meta-analysis. Overall, 120 patients received locking-plate fixation with bone-graft augmentation, 179 patients received locking-plate fixation with cement augmentation, and 336 patients received locking-plate fixation without augmentation. No statistically relevant differences between the augmented and non-augmented cohorts were found in terms of the Disabilities of the Arm, Shoulder and Hand questionnaire score and Constant-Murley Score. The cement-augmented group had a significantly lower rate of complications compared to the non-augmented group. Conclusion: While locking-plate fixation with cement augmentation appears to produce a lower complication rate compared to locking-plate fixation alone, functional outcomes seem comparable between augmented and non-augmented techniques.

ABSTRACT

OBJECTIVE: Fractures of the proximal humerus (PHF) are commonly treated conservatively. Evidence suggests that a period of immobilization of one week or less may lead to some advantages compared to a traditional 3-4 weeks of immobilization. The purpose of this systematic review was to assess the clinical and radiological results in the case of early rehabilitation vs. delayed rehabilitation after PHF. MATERIALS AND METHODS: In July 2023, a literature search was carried out on the PubMed, MEDLINE, and Embase databases to identify all the randomized trials comparing early rehabilitation vs. delayed rehabilitation after PHF. The following data were extracted from each included study: patients' demographics, study design and level of evidence, follow-up times, treatment groups, evaluation scores adopted, and overall clinical and radiological findings. The quality of the trials was assessed using the Cochrane Risk of Bias Assessment. RESULTS: A total of 5 studies, including 378 patients and dealing with early vs. delayed rehabilitation in case of conservative treatment of PHF, were included in this study. Early rehabilitation was started within 1 week and consisted mainly of pendulum exercise and progressive passive mobilization. Early rehabilitation was associated with better pain and functional scores within the first 3 months in 3 studies. No difference in pain or function was reported at 6 months or longer follow-up, and no differences in complications rate were observed between early vs. delayed rehabilitation groups. CONCLUSIONS: This systematic review suggests that early mobilization within one week in case of conservative treatment of PHF leads to improved function recovery and reduced pain, especially in the first months of rehabilitation, without differences at longer follow-up and without increasing complications rate. Reducing immobilization time could accelerate function recovery and regaining independence in daily life activities.

ABSTRACT

A high failure rate is associated with fracture plates in proximal humerus fractures. The causes of failure remain unclear due to the complexity of the problem including the number and position of the screws, their length and orientation in the space. Finite element (FE) analysis has been used for the analysis of plating of proximal humeral fractures, but due to computational costs is unable to fully explore all potential screw combinations. Surrogate modelling is a viable solution, having the potential to significantly reduce the computational cost whilst requiring a moderate number of training sets. This study aimed to develop adaptive neural network (ANN)-based surrogate models to predict the strain in the humeral bone as a result of changing the length of the screws. The ANN models were trained using data from FE simulations of a single humerus, and after defining the best training sample size, multiple and single-output models were developed. The best performing ANN model was used to predict all the possible screw length configurations. The ANN predictions were compared with the FE results of unseen data, showing a good correlation (R2 = 0.99) and low levels of error (RMSE = 0.51%-1.83% strain). The ANN predictions of all possible screw length configurations showed that the screw that provided the medial support was the most influential on the predicted strain. Overall, the ANN-based surrogate model accurately captured bone strains and has the potential to be used for more complex problems with a larger number of variables.

ABSTRACT

BACKGROUND: Reverse shoulder arthroplasty (RSA) is a frequently used therapy for complex proximal humeral fractures and posttraumatic disorders. The present study's purpose was to assess the clinical and radiological outcome of primary and secondary RSA, and to analyze the impact of refixation of the greater tuberosity (GT). PATIENTS AND METHODS: 28 patients with primary fracture RSA and 18 patients with RSA due to posttraumatic disorders were examined with a mean clinical follow-up of 2.5 ± 1.73 years. Operative details and radiographs were retrospectively reviewed. Additional analyses were performed for healed and non-healed GT in primary RSA. RESULTS: Patients with fracture RSA had higher Constant-Murley score (CMS) than secondary RSA without reaching significance (p = 0.104). No significant difference was present for the quality of life measured by the Short Form 36 (SF 36) and the range of motion. In primary RSA, 78.6% GT healed anatomically. Compared to non-healed GT, patients with healed GT had a significantly higher CMS (p = 0.011), external rotation (p = 0.026) and forward flexion (p = 0.083), whereas DASH score was lower without a significant difference (p = 0.268). SF 36 showed no significant difference. Patients with healed GT had a more neutral glenoid version (p = 0.009). CONCLUSION: Superior range of motion and clinical outcome scores were present for anatomically healed GT. Therefore, refixation of the tuberosities is recommended. Secondary RSA can result in inferior results compared to primary RSA, so patients need to be adequately informed.

ABSTRACT

Fractures of the proximal humerus with medial column instability are challenging and present an unacceptable rate of complications and reoperations. Despite good results reported with the use of locking plates and augmentation techniques using bone graft or a second plate, varus subsidence and fixation failure have been frequently reported. We describe the case of a patient presenting with a complex, multifragmentary proximal humerus fractures successfully treated with open anatomic reduction and internal fixation using a locking plate augmented with lateral traction using three bone anchors in the humerus head. After 18 months, the patient reported fully recovering the mobility and functionality of the operated shoulder. The use of bone anchors pulling the humeral in three different directions like three vectors applied from medial to lateral, posterior to anterior and lateral to anterior help to reduce the most important deformities (varus and retroversion) by applying the tension band principle. This is an interesting approach to avoid primary and secondary reduction loss of the proximal fractures of the humerus with postero-medial cortical defect. The procedure is a good alternative to be used in patients with failure or insufficiency of the medial wall and marked varus.

ABSTRACT

INTRODUCTION: The majority of all proximal humeral fractures (PHFs) are treated non-surgically. Due to the risk of early secondary fracture displacement patients with non-surgically treated PHFs routinely undergo serial clinical and radiological evaluations. However, the value of these routine follow-up visits is unclear. This study aimed to examine the rate of early conversion to surgery in non-surgically treated PHFs. Moreover, the associations between patient and fracture characteristics and the risk of conversion to surgery were explored in order to assess the need for routine follow-ups. METHODS: Data on all patients aged ≥18 years with a non-surgically treated PHF registered between 2013 and 2021 were extracted from the Swedish Fracture Register. Early change of treatment from non-surgical to surgical is an optional treatment modality in the SFR. The rate of early conversion to surgery within 60 days from injury was analyzed in relation to age and sex of the patient, energy level at injury and fracture morphology according to the AO/OTA classification. RESULTS: A total of 31,761 primarily non-surgically treated PHFs (mean age 70 years: 76 % female) were included in the study. The overall rate of early conversion to surgery was 3.7 %. Younger age and increasing fracture severity were associated with a higher conversion rate to surgery. Patients ≥80 years and those with the three most common fracture types (A1, A2, and B1) had <2 % early conversion to surgery. In contrast, patients with C-type fractures, unstable/displaced fractures (A3, B2, and C2), or fracture dislocations (A1.3, B3, and C3) had a substantially higher risk (5.0-20 %) of early conversion. CONCLUSION: The overall risk of early conversion to surgery in non-surgically treated PHFs is low and can be further predicted based on patient age and fracture morphology. These results could have implications regarding which patients are in need of routine follow-ups. LEVEL OF EVIDENCE: Level II; Retrospective design; Prognosis study.

ABSTRACT

In conservative treatment for proximal humerus fractures (PHFs), the immobilization position of the affected arm should not be determined uniformly. The aim of this study is to investigate the optimal immobilization position for conservative treatment of different types of PHFs. We hypothesized that the optimal position minimizing the deforming force in PHFs depends on the fracture components involved. PHF models involving either the surgical neck (SN) or greater tuberosity (GT) were created using 12 fresh-frozen cadaveric shoulders. In the SN model, the deforming forces on the pectoralis major muscle were measured in full adduction by increasing external rotation. In the GT model, the deforming force of the supraspinatus muscle was measured in neutral rotation by decreasing abduction, and the deforming force of the infraspinatus muscle was measured in full adduction by increasing internal rotation, respectively. In the SN model, the deforming force of the pectoralis major muscle increased significantly with external rotation from full internal rotation to neutral rotation (P = 0.006), indicating that the arm should be placed in full internal rotation. In the GT model, the deforming force of the supraspinatus muscle increased significantly with adduction from 45° of abduction to full adduction (P = 0.006); the deforming force of the infraspinatus muscle increased significantly with internal rotation from neutral rotation to full internal rotation (P = 0.006). These findings should be considered when placing the arm in abduction and neutral rotation so as to minimize the deforming force by either the supra or infraspinatus muscle. In conservative treatment for PHFs, the affected arm should be placed in a position that minimizes the deforming force on the fracture components involved.
