Early Clinical Efficacy of Small Incision Reduction and Superior Closed Pin Fixation of Goss-Ideberg Type III Glenoid Fractures using X-ray and CT Scan.

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.

Cemented Versus Uncemented Reverse Shoulder Arthroplasty Treatment of Proximal Humerus Fractures: National Shoulder Arthroplasty Data from Türkiye.

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.

Comparison between CFR-PEEK and titanium plate for proximal humeral fracture: A meta-analysis.

OBJECTIVES: The aim of the present meta-analysis was to compare the efficacy and safety of the carbon fiber-reinforced polyetheretherketone (CFR-PEEK) and titanium plate for the treatment of proximal humeral fractures (PHFs) from clinical comparative trials. MATERIALS AND METHODS: A comprehensive search of English databases was carried out, such as PubMed, Web of Science, ScienceDirect, Springer and Cochrane Library databases. The RevMan version 5.1 software was applied for statistical analysis, and the mean difference (MD) and risk difference (RD) as the combined variables, and "95%" as the confidence interval (CIs). RESULTS: One randomized-controlled trial and five retrospective controlled studies including 282 PHFs were considered eligible and finally included. Meta-analysis demonstrated that there were significant differences in Constant score (CS) (MD=9.23; 95% CI: 5.02, 13.44; p<0.0001), anterior elevation (MD=18.83; 95% CI: 6.27, 31.38; p=0.003), lateral elevation (MD=18.42; 95% CI: 3.64, 33.19; p=0.01) and adduction (MD=3.53; 95% CI: 0.22, 6.84; p=0.04). No significant differences were observed regarding Constant score compared to the contralateral shoulder, Oxford Shoulder Score, internal rotation, external rotation, screw perforation and cutout, varus/valgus malalignment, humeral head collapse/necrosis, implant removal, and revision surgery between the two groups. CONCLUSION: Compared to titanium plate, CFR-PEEK plate showed better Constant score, anterior elevation, lateral elevation and adduction in treating PHFs. The complications are comparable to those achieved with conventional titanium plates.

A Retrospective Study of 1076 Cases of Shoulder Dislocation at a Single Center in Türkiye to Evaluate the Role of Post-Reduction Radiography in the Detection of Clinically Significant Fractures.

BACKGROUND The role of post-reduction radiography in patients with shoulder dislocation remains controversial. Therefore, this retrospective study of 1076 cases of shoulder dislocation at a single center in Türkiye aimed to evaluate the role of post-reduction radiography in the detection of clinically significant fractures. MATERIAL AND METHODS Patients with radiographically confirmed anterior shoulder dislocation were included in the study, and their demographic data, mechanism of injury, pre- and post-reduction radiograph readings, reduction method, and patient outcome were recorded. The study analyzed patients who had pre- and post-reduction anterior-posterior and axillary shoulder radiographs. RESULTS During the 44-month study period, a total of 1076 patients were examined, and their pre- and post-reduction radiographs were reviewed by an independent radiologist. Of these patients, 27 (2.6%) had a fracture on their pre-reduction radiographs, while 32 (3.1%) had a fracture on their post-reduction radiographs. The difference between the 2 groups was not statistically significant (P=0.142). The study found that patients who did not undergo a post-reduction radiograph spent an average of 106 min in the emergency department, while patients who had the radiograph and were discharged spent an average of 237 min. The hospital stay of patients who had the radiograph was also significantly longer (P<0.01). CONCLUSIONS Our study supports that routine use of post-reduction radiographs in all cases of anterior shoulder dislocation may not be necessary and could potentially expose patients to unnecessary radiation exposure and healthcare costs. Shortening the examination time in the emergency department by not taking a follow-up radiograph will help prevent overcrowding.

Clinical validation of artificial intelligence-based preoperative virtual reduction for Neer 3- or 4-part proximal humerus fractures.

BACKGROUND: If reduction images of fractures can be provided in advance with artificial-intelligence (AI)-based technology, it can assist with preoperative surgical planning. Recently, we developed the AI-based preoperative virtual reduction model for orthopedic trauma, which can provide an automatic segmentation and reduction of fractured fragments. The purpose of this study was to validate a quality of reduction model of Neer 3- or 4-part proximal humerus fractures established by AI-based technology. METHODS: To develop the AI-based preoperative virtual reduction model, deep learning performed the segmentation of fracture fragments, and a Monte Carlo simulation completed the virtual reduction to determine the best model. A total of 20 pre/postoperative three-dimensional computed tomography (CT) scans of proximal humerus fracture were prepared. The preoperative CT scans were employed as the input of AI-based automated reduction (AI-R) to deduce the reduction models of fracture fragments, meanwhile, the manual reduction (MR) was conducted using the same CT images. Dice similarity coefficient (DSC) and intersection over union (IoU) between the reduction model from the AI-R/MR and postoperative CT scans were evaluated. Working times were compared between the two groups. Clinical validity agreement (CVA) and reduction quality score (RQS) were investigated for clinical validation outcomes by 20 orthopedic surgeons. RESULTS: The mean DSC and IoU were better when using AI-R that when using MR (0.78 ± 0.13 vs. 0.69 ± 0.16, p < 0.001 and 0.65 ± 0.16 vs. 0.55 ± 0.18, p < 0.001, respectively). The working time of AI-R was, on average, 1.41% of that of MR. The mean CVA of all cases was 81%±14.7% (AI-R, 82.25%±14.27%; MR, 76.75%±14.17%, p = 0.06). The mean RQS was significantly higher when AI-R compared with MR was used (91.47 ± 1.12 vs. 89.30 ± 1.62, p = 0.045). CONCLUSION: The AI-based preoperative virtual reduction model showed good performance in the reduction model in proximal humerus fractures with faster working times. Beyond diagnosis, classification, and outcome prediction, the AI-based technology can change the paradigm of preoperative surgical planning in orthopedic surgery. LEVEL OF EVIDENCE: Level IV.

Enhanced Outcomes and Safety of Reverse Shoulder Arthroplasty in Rotator Cuff Deficiency and Proximal Humerus Fractures: A 22-Patient Retrospective Analysis.

BACKGROUND Reverse shoulder arthroplasty (RSA) is an accepted treatment that provides reproducible results in the treatment of rotator cuff deficiency and proximal humerus fractures. This single-center study aimed to evaluate the outcomes from reverse shoulder arthroplasty for rotator cuff insufficiency and proximal humerus fractures in 22 patients from a single center. MATERIAL AND METHODS Twenty-two patients were included in the study. The median age of the patients was 66 years (Range: 58-95). Proximal humerus fractures were diagnosed using X-ray and CT, while rotator cuff tears were diagnosed using MRI. For the assessment of joint function, the Constant-Murley score, the American Shoulder and Elbow Surgeons (ASES), and the Disabilities of Arm, Shoulder, and Hand (DASH) scores were used as patient-reported outcome measures. Kaplan-Meier analysis was conducted to evaluate implant survival. RESULTS The mean follow-up duration was 4.05±1.2 years. Significant improvements were observed: ASES Score: Increased from 35.8±2.8 to 81.3±5.4 (p<0.001). VAS Pain Score: Decreased from 7.3±1 to 2.9±0.9 (p<0.001). DASH Score: Improved from 66.3±4.3 to 32.5±3.6 (p<0.001). Constant-Murley Score: Increased from 48.3±3.5 to 74.6±7.7 (p<0.001). Kaplan-Meier analysis estimated implant survival at 6.7 years (95% CI, 6.3-7.2). CONCLUSIONS When performed with appropriate indications, RSA yields positive results, as seen in the literature and our study. Interscalene block anesthesia, advancements in implant technology, and adherence to surgical procedures can reduce RSA complications and ensure its safe application.

Axillary Artery Injury Associated with Dislocated or Displaced Proximal Humeral Fracture: A Report of 3 Cases.

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.

Straight intramedullary MultiLoc nails for displaced proximal humeral fractures: health status, radiographic results, clinical outcome, and complications.

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.

Construction and validation of a nomogram for blood transfusion after open reduction and internal fixation (ORIF) of proximal humeral fractures in the elderly: a cross-sectional study.

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.).

Results of transosseous suture fixation in four-part valgus impacted fractures of the proximal humerus.

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.

Comparison of classical and minimally invasive superolateral approach for reconstruction of proximal humerus fractures with locking plates.

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.

Mid- to long-term outcomes of proximal humerus fractures treated with open reduction, plate fixation, and iliac bone autograft augmentation.

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.

Proximal humeral fractures with vascular compromise.

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.

Use of light activated intramedullary device for revision of a proximal humerus fracture: a case study.

BACKGROUND: Post-operative non-compliance is a risk factor for fracture fixation failure and presents a challenge for revision surgery planning. We present a patient who underwent revision surgery for a proximal humerus fracture with lateral locked plating augmented with a UV light activated intramedullary implant. CASE: A 45-year-old woman with a history of alcoholism presented with a proximal humerus fracture. After undergoing open reduction internal fixation with a lateral locking plate, the patient suffered a fall secondary to delirium tremens. New radiographs demonstrated displacement of the fracture with failure of screws. Revision surgery consisting of removal of the initial construct as well as open reduction internal fixation via lateral locking plate, augmented with a UV-activated intramedullary cement implant, was performed. CONCLUSION: This is the first case report describing the use of a UV-activated intramedullary cement implant to augment the use of lateral locked plating for proximal humerus fractures. This case illustrates the successful management using UV-activated intramedullary cement to augment fixation, specifically in a patient with risk factors and post-operative non-compliance that predispose to fixation failure.

The ballistic articular structure injury classification (BASIC) system: clarifying ballistic articular injuries.

PURPOSE: This study aims to (1) devise a classification system to categorize and manage ballistic fractures of the knee, hip, and shoulder; (2) assess the reliability of this classification compared to current classification schemas; and (3) determine the association of this classification with surgical management. METHODS: We performed a retrospective review of a prospectively collected trauma database at an urban level 1 trauma centre. The study included 147 patients with 169 articular fractures caused by ballistic trauma to the knee, hip, and shoulder. Injuries were selected based on radiographic criteria from plain radiographs and CT scans. The AO/OTA classification system's reliability was compared to that of the novel ballistic articular injury classification system (BASIC), developed using a nominal group approach. The BASIC system's ability to guide surgical decision-making, aiming to achieve stable fixation and minimize post-traumatic arthritis, was also evaluated. RESULTS: The BASIC system was created after analysing 73 knee, 62 hip, and 34 shoulder fractures. CT scans were used in 88% of cases, with 44% of patients receiving surgery. The BASIC classification comprises five subgroups, with a plus sign indicating the need for soft tissue intervention. Interrater reliability showed fair agreement for AO/OTA (k = 0.373) and moderate agreement for BASIC (k = 0.444). The BASIC system correlated strongly with surgical decisions, with an 83% concurrence in treatment choices based on chart reviews. CONCLUSIONS: Conventional classification systems provide limited guidance for ballistic articular injuries. The BASIC system offers a pragmatic and reproducible alternative, with potential to inform treatment decisions for knee, hip, and shoulder ballistic injuries. Further research is needed to validate this system and its correlation with patient outcomes. LEVEL OF EVIDENCE: Level III, Diagnostic Study.

Preoperative chronic steroid use as a risk factor for complications following open reduction internal fixation for proximal humerus fracture.

PURPOSE: The primary objective of this study was to investigate the association between preoperative chronic steroid use and postoperative complications following open reduction internal fixation (ORIF) for proximal humerus fractures (PHF). METHODS: The American College of Surgeons National Surgical Quality Improvement (ACS-NSQIP) database was queried for all patients who underwent PHF ORIF between 2015 and 2021. A total of 6,273 patients were included in this study, of which 3.4% (n = 212) were in the chronic steroid use cohort. Patient characteristics including demographics, comorbidities, and 30-day postoperative complications after PHF ORIF were collected. Bivariate logistic regression and multivariate logistic regression analysis, adjusted for all significantly associated variables, was conducted to investigate the relationship between preoperative chronic steroid use and postoperative complications. RESULTS: Chronic steroid use was significantly associated with age ≥ 75 (p < 0.001), male gender (p =0.006), dependent functional status (p = 0.008), American Society of Anesthesiologist (ASA) ≥ 3 (p < 0.001), CHF (p = 0.007), hypertension (p < 0.001), COPD (p < 0.001), bleeding disorder (p = 0.007), ascites (p = 0.040), disseminated cancer (p< 0.001), and systemic sepsis (p < 0.001). After adjusting for all significantly associated variables, chronic steroid use was independently associated with major complication (OR 1.60, 95% CI 1.06-2.43; p = 0.026), and non-home discharge (OR 1.05, 95% CI 1.01-1.08; p = 0.014). CONCLUSION: Preoperative chronic steroid use is associated with increasing rate of postoperative complications following PHF ORIF. Better understanding and characterizing chronic steroid use as a preoperative risk factor can aid physicians in risk stratification to reduce rates of postoperative complications following PHF ORIF.

Combination of Anatomical Plates and Rotator Cuff Reinforcement for Minimally Invasive Treatment of Greater Tuberosity Fractures of the Humerus.

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.

Clinical and radiographic results of locking plate with medial support screw in Proximal Humerus fracture - the more, the better?

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.

Augmented versus non-augmented locking-plate fixation in proximal humeral fractures.

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.
