Free functional gracilis transfer for reconstruction of isolated anterior deltoid atrophy following surgical proximal humerus fixation

BackgroundPalsy of the clavicular head of the deltoid is a complication after surgical fixation of proximal humerus fractures. Flexion of the shoulder joint may be impaired as a result. Additionally, patients may complain of joint instability, visible atrophy and pain. Where nerve reconstruction is not possible, muscle transfers remain as secondary reconstructive procedures. MethodsThree patients suffering from anterior deltoid palsy after proximal humerus fixation received a free functional gracilis transfer to the shoulder. Postoperatively, patients underwent biofeedback-based rehabilitation. Before and after the intervention, subjective complaints, pain level and active range of motion (ROM) were recorded. At the final follow-up patients completed a Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. ResultsThe surgery was successful in all patients with first muscle signals registered through sEMG approximately four months postoperatively. At the latest follow-up (> 3 years), the patients showed improved shoulder stability and pain scores. In two patients with preoperative restrictions, active ROM improved. The DASH score showed minimal to no disability in two patients and moderate disability in the third. Two patients voiced satisfaction with the restoration of the ventral bulk of the shoulder. ConclusionsThe free functional gracilis muscle transfer is a novel approach for secondary reconstruction in patients with anterior deltoid atrophy who don’t qualify for nerve intervention. It addresses shoulder instability and pain and may improve active ROM. The addition of fresh muscle tissue to the ventral shoulder can improve its natural contour and prevent protrusion of the humeral head.

United States opioid prescribing trends after shoulder surgery and their correlation with opioid misuse

BACKGROUNDOrthopedic surgery has been highlighted as a contributor to the opioid epidemic. There is a paucity of literature focused specifically on opioid prescribing trends following shoulder surgery. Our aims were to describe national and regional trends in opioid prescribing following total shoulder arthroplasty (TSA), proximal humerus fracture fixation, and rotator cuff repair (RCR), and to correlate opioid prescribing trends after shoulder surgery with regional heroin use and new opioid misuse diagnoses. METHODSThis is a retrospective study of 218,577 patients from a commercial insurance dataset who had undergone orthopedic shoulder procedures from 2014-2020. Opioid prescription data within 90-day postop were converted to morphine milligram equivalents (MME). Multivariate modelling was used to evaluate independent associations between MME’s prescribed and subsequent new postoperative diagnosis of opioid dependence. Additionally, longitudinal mixed effects modeling was employed to understand aggregated prescriber habits by state over time and the subsequent effects on estimates of state heroin use and drug overdose deaths. RESULTSFrom 2014 to 2020, the mean number of MMEs prescribed nationally decreased by over 50% for TSA, proximal humerus fracture fixation, and RCR. Over the study period, most states demonstrated an overall downtrend of 90-day opioid prescribing for these procedures.Individuals with a new opioid misuse diagnosis following shoulder surgery were found to be younger (SMD=0.27, p<0.001), have increased comorbidities (SMD=0.38, p<0.001), and increased MME’s prescribed (SMD=0.94, p<0.001). Increased comorbidity score (OR=3.28, p<0.001) and increased 90-day MME’s prescribed (OR=1.05, p<0.001) were all found to increase the odds ratio of a postoperative opioid misuse diagnosis in patient’s undergoing shoulder surgery, while increased age (OR=0.97, p<0.001) and patient’s undergoing RCR (OR=0.79, p=0.001) were found to have a decreased odds ratio of developing a new opioid misuse diagnosis.The predictors of regional heroin use included the within-state 90-day MMEs prescribed (p=0.002). The predictors of drug overdose death included year (p<0.001), but did not include type of surgery or 90-day MMEs. CONCLUSIONOrthopedic surgeons successfully reduced the number of opioids prescribed nationally after shoulder surgeries by over 50% during our study period with similar trends seen at the state level. Our data indicate a relationship between increased opioid prescribing after shoulder surgery and heroin use. This study highlights that while progress has been made, there is evidence that opioid prescribing following shoulder surgery is associated with the more widespread opioid epidemic, and that more research is needed to further lower postoperative opioid misuse in the future.

Assessing Functional Outcome of PHILOS Plate Fixation in Proximal Humerus Fractures- A Prospective Study

Introduction: Despite the availability of numerous treatment options, managing unstable proximal humeral fractures remains a significant surgical challenge. Utilizing a PHILOS plate is an effective surgical technique for addressing these fractures. This approach provides stability and support to the fracture site, promoting proper healing and potentially improving patient outcomes. Aim of the study: The aim of this study was to assess the functional outcome of PHILOS plate fixation in proximal humerus fractures. Methods: This prospective study was conducted in the the Department of Orthopedic Surgery, National Institute of Traumatology and Orthopedic Rehabilitation (NITOR), Sher-e-Bangla Nagar, Dhaka, Bangladesh during the period from January 2009 to December 2010. A total of 80 patients aged over 18 years were included in the study. Patients with open, pathological and ipsilateral distal fractures in the same limb were excluded from the study. Result: The youngest and the oldest one were 23 and 78 years respectively. Majority of the patients were male and business was their main occupation. Fifty patients (62.5%) presented with 3-part fractures, ten (12.5%) with four-part fractures and twenty (25%) with fracture dislocation. The interval between injury and plate fixation was 18 days and minimum and maximum interval was 2 and 78 days respectively. Majority (92.5%) of the injury was caused by high-velocity accident. Evaluation of the outcome at 6 months showed that 62.5 percent of patients had good outcome, 25 percent patients had fair outcome. Conclusion: PHILOS plate fixation for proximal humeral fractures provides stable fixation and good functional outcomes, particularly in elderly patients.

Assessing screw length impact on bone strain in proximal humerus fracture fixation via surrogate modelling.

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.

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

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). 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. 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). 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.

Identifying clinically meaningful subgroups following open reduction and internal fixation for proximal humerus fractures: a risk stratification analysis for mortality and 30-day complications using machine learning

Identification of prognostic variables for poor outcomes following open reduction internal fixation (ORIF) of displaced proximal humerus fractures have been limited to singular, linear factors and subjective clinical intuition. Machine learning (ML) has the capability to objectively segregate patients based on various outcome metrics and reports the connectivity of variables resulting in the optimal outcome. Therefore, the purpose of this study was to (1) use unsupervised ML to stratify patients to high-risk and low-risk clusters based on postoperative events, (2) compare the ML clusters to the American Society of Anesthesiologists (ASA) classification for assessment of risk, and (3) determine the variables that were associated with high-risk patients after proximal humerus ORIF. The American College of Surgeons-National Surgical Quality Improvement Program database was retrospectively queried for patients undergoing ORIF for proximal humerus fractures between 2005 and 2018. Four unsupervised ML clustering algorithms were evaluated to partition subjects into "high-risk" and "low-risk" subgroups based on combinations of observed outcomes. Demographic, clinical, and treatment variables were compared between these groups using descriptive statistics. A supervised ML algorithm was generated to identify patients who were likely to be "high risk" and were compared to ASA classification. A game-theory-based explanation algorithm was used to illustrate predictors of "high-risk" status. Overall, 4670 patients were included, of which 202 were partitioned into the "high-risk" cluster, while the remaining (4468 patients) were partitioned into the "low-risk" cluster. Patients in the "high-risk" cluster demonstrated significantly increased rates of the following complications: 30-day mortality, 30-day readmission rates, 30-day reoperation rates, nonroutine discharge rates, length of stay, and rates of all surgical and medical complications assessed with the exception of urinary tract infection (P<.001). The best performing supervised machine learning algorithm for preoperatively identifying "high-risk" patients was the extreme-gradient boost (XGBoost), which achieved an area under the receiver operating characteristics curve of 76.8%, while ASA classification had an area under the receiver operating characteristics curve of 61.7%. Shapley values identified the following predictors of "high-risk" status: greater body mass index, increasing age, ASA class 3, increased operative time, male gender, diabetes, and smoking history. Unsupervised ML identified that "high-risk" patients have a higher risk of complications (8.9%) than "low-risk" groups (0.4%) with respect to 30-day complication rate. A supervised ML model selected greater body mass index, increasing age, ASA class 3, increased operative time, male gender, diabetes, and smoking history to effectively predict "high-risk" patients.

Comparison of clinical outcomes and complications in 2-part vs. 3- or 4-part proximal humerus fractures treated using an intramedullary nail designed to capture the tuberosities

Intramedullary nail fixation for proximal humerus fractures has been shown to provide satisfactory results. The quality of reduction correlates with clinical outcomes, the rate of complications, avascular necrosis, and postoperative loss of fixation. The purpose of this study was to evaluate the clinical outcomes and complications of 2-part proximal humerus fractures compared to 3- or 4-part proximal humerus fractures. A single-center retrospective review was carried out of patients who underwent an intramedullary nail for a proximal humerus fracture by one of three surgeons between the years of 2009 and 2022, and who had a minimum of 12-months follow-up. Fracture pattern, American Shoulder and Elbow Surgeons score, Single Assessment Numeric Evaluation score, satisfaction, pain score, range of motion, and complications were recorded. The mechanism of injury (high energy vs. low energy), method of reduction (open vs. percutaneous), and evidence of radiographic healing were assessed. A P value of <.05 was considered to be statistically significant. The study included 78 patients (62 female, 16 male). The number of patients in each group (2-part, N=32 vs. 3- or 4-part, N=46), mean age (2-part, 64 vs. 3- or 4-part,61), follow-up (2-part, 42.5 months vs. 3- or 4-part, 34.5 months), injury type (2-part, 88% low energy vs. 3- or 4-part, 78% low energy), and method of reduction (2-part, 81% percutaneous vs. 3- or 4-part 72% percutaneous) were similar among the two groups. There was fracture union in all patients. All patients demonstrated satisfactory patient-reported outcome measures. However, 2-part fractures did have a significantly lower pain score, higher Single Assessment Numeric Evaluation score, and higher percentage of patients being satisfied or very satisfied when compared to 3- or 4-part fractures. The rate of subsequent procedures was 13% (n=4) in 2-part fractures compared to 19% (n=9) in 3- or 4-part fractures but was not statistically significant (P=.414). The overall rate of conversion to arthroplasty was 3.2% in 2-part fractures and 10.4% in 3- or 4-part fractures. Multipart proximal humerus fractures remain difficult to treat. However, this study demonstrates an overall acceptable outcome with improvement in range of motion, patient-reported outcomes, and similar complication rates between 2-part and 3- or 4-part proximal humerus fractures treated with an intramedullary nail. However, the improvement in certain parameters is not as marked in 3- or 4-part fractures as 2-part fractures.

Proximal humerus open reduction internal fixation with and without biceps tenodesis: assessment of early clinical outcomes

BackgroundThe role of biceps tenodesis (BT) during open reduction and internal fixation (ORIF) of proximal humerus fractures (PHF) remains unclear. A subset of patients undergoing ORIF have persistent pain with unclear etiology. The purpose of our study was to compare outcomes of ORIF of proximal humerus fractures with and without concomitant biceps tenodesis (BT). We hypothesize patients undergoing biceps tenodesis at the time of ORIF will have improved patient-reported outcome scores with fewer secondary procedures related to treatment of the biceps. MethodsIn this retrospective cohort study, all patients undergoing ORIF for a PHF at a single level one trauma center from January 2019 to June 2022 were reviewed. Patients under the age of 18 were excluded. Primary outcomes were PROMIS physical function, depression, and pain interference scores at 5 time points up to final follow-up. Secondary outcomes included total operative time, complications, subsequent procedures, steroid injections, and range of motion. Chi-square tests were performed for categorical values and paired t-tests for continuous variables. Results71 patients met inclusion criteria: 41 undergoing ORIF without BT, and 30 undergoing ORIF with BT. Average follow-up was 11 months. There were no statistically significant differences in patient demographics between groups. There were no differences in PROMIS scores at any time point postoperatively. At final follow-up patients in the ORIF with BT group had higher forward flexion than those who did not undergo BT (142 vs. 123 degrees, respectively, p < .02). There were no differences in surgical time, revision rates, postsurgical complications, or postoperative injections between groups. ConclusionBiceps tenodesis performed during ORIF of PHFs did not result in significantly different functional or patient-reported outcomes between groups, except for greater forward flexion at final follow-up. Although BT was done more commonly in severe PHFs, patients in both groups had similar rates of subsequent biceps-related procedures and revision surgery.

Intramedullary Plating of Complex Proximal Humerus Fractures: A Case Series.

To assess fracture union rates using novel intramedullary plate technique. Post-operative humeral neck-shaft angles, patient range of motion and complication profile were secondary outcomes of interest. Single surgeon, retrospective case series of surgical technique at major trauma centre in Scotland. A 2.0mm mini-fragment plate was secured to the humeral head to act as an intramedullary strut during fixation in complex proximal humerus fractures. Fracture union and neck-shaft angle were assessed radiologically, whilst range of motion and complication profiles were assessed clinically. Twelve patients were followed up for an average of 10 months post-operatively. All achieved bony union with a mean neck-shaft angle of 128°. Mean range of motion values were 100° forward elevation, 83° abduction, 60° internal rotation and 37° external rotation. Four patients required further surgical intervention- two for hardware prominence, one for adhesive capsulitis and one for subsequent rotator cuff failure. There were no cases of avascular necrosis or infection. This novel technique addresses the established biomechanical propensity of proximal humerus fractures to fail in varus collapse and screw cut-out. This method provides an alternative to arthroplasty in the most severe proximal humerus fractures and is readily adopted via standard orthopaedic kit.

Functional Outcomes of Open Reduction and Internal Fixation in Proximal Humerus Fractures by Philos Plate

INTRODUCTION Proximal humerus fractures are one very common and usually occur in elderly people. These fractures are usually associated with some degree of comminution and deformity. Therefore, good anatomical reduction of fracture fragments and early mobilization are the main component for optimal outcomes of involved limb. This study was intended to evaluate the functional outcome of proximal humerus fracture in adults managed by open reduction and internal fixation (ORIF) by proximal humerus interlocking osteosynthesis (PHILOS) plate. MATERIAL AND METHODS This prospective and observational hospital based study was carried out in Orthopedics Department of Universal College of medical Sciences-Teaching Hospital (UCMS-TH) from October 2021 to September 2023. All patients with proximal humerus fractures who fulfilled the inclusion criteria and who underwent open reduction and internal fixation by PHILOS plate were enrolled in the study. Functional outcome was assessed according to Constant murley scoring system and Visual analogue score. Post-operatively patients were regularly followed at 6 weeks, 3 months and 6 months. RESULTS In this study of 60 cases, the mean age group was 55.38±11.40 years and male patients outnumbered female patients (39 males and 21 females). 36 cases (60%) were of right side and 24 (40%) were of left side. Majority of the fractures were due to fall injury (57%) followed by road traffic accident (35%). The mean Constant Murley Score was 78.15±5.620 and VAS (visual analogue score) was 1.88±0.865. CONCLUSION Open reduction and internal fixation by PHILOS plate is an effective procedure providing good anatomical restoration and early mobilization in proximal humerus fracture thus providing good functional outcome.

Postoperative Opioid Dependence in Patients Undergoing Either Total or Reverse Shoulder Arthroplasty for Proximal Humerus Fracture Fixation.

In elderly patients who have proximal humerus fractures, treatment commonly involves total shoulder arthroplasty (TSA) or reverse shoulder arthroplasty (RSA). Following these procedures, patients often require opioids for postoperative analgesia. This common scenario is of clinical and societal importance, as increased postoperative opioid usage has been shown to worsen outcomes and increase the likelihood for dependence. We aimed to compare postoperative opioid use in patients undergoing either TSA or RSA for fixation of their proximal humerus fracture. Specifically, we assessed: (1) postoperative opioid use at two, four, six, eight, and greater than eight weeks postoperatively; (2) aseptic revision rates at 90-days, one year, and two years postoperatively; and (3) periprosthetic joint infection (PJI) rates at 90-days, one year, and two years postoperatively between patients undergoing TSA or RSA for the surgical management of their proximal humerus fractures. For this review, we queried a national all-payer database from October 1, 2015 to October 31, 2020 (n=1.5 million) for all patients who had a "proximal humerus fracture" diagnosis who underwent either TSA or RSA. There were two cohorts: patients undergoing TSA (n=731) and patients undergoing RSA (n=731). Bivariate Chi-square analyses. We found no differences (p>0.05) in opioid use postoperatively in patients undergoing RSA for proximal humerus management compared to patients undergoing TSA after two weeks. There was not a significant difference in aseptic revision or PJI rates between the two cohorts (all p>0.05). The evidence comparing opioid use in patients undergoing either TSA or RSA for proximal humerus fracture fixation is lacking. Our study specifically showed no differences in opioid use postoperatively in patients undergoing RSA for proximal humerus management compared to patients undergoing TSA.

Predictors of Extended Length of Stay Following Open Reduction and Internal Fixation for Proximal Humerus Fractures

An extended length of stay following open reduction and internal fixation (ORIF) for proximal humerus fractures (PHFs) is associated with increased patient morbidity and health care costs. The primary purpose of this study was to identify risk factors for an extended length of stay following ORIF for PHF. All patients who underwent ORIF for PHF between 2015 and 2021 were queried from the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Patient demographics, comorbid conditions, and postoperative complications within 30 days of procedure were collected. Extended length of stay (eLOS) was defined by ≥ 3 days from operation to discharge. Multivariate logistic regression was employed to identify predictors of eLOS following ORIF. Characteristics of patients significantly associated with eLOS included age ≥ 75 years (p < .001), male gender (p < 0.001), body mass index (BMI) < 18.5 (P= .001), American Society of Anesthesiologists (ASA) classification ≥ 3 (P < .001), dependent functional status (P < .001), noninsulin-dependent diabetes (P= .037), insulin-dependent diabetes (P < .001), chronic obstructive pulmonary disease (P < .001), congestive heart failure (CHF) (P < .001), hypertension (P < 0.001), dialysis (P < .013), disseminated cancer (P < 0.001), chronic steroid use (P= .004), and bleeding disorder (P < .001). Independent predictors of eLOS were age ≥ 75 years (OR= 2.69; P < .001), BMI < 18.5 (OR= 1.70; P= .016), ASA ≥ 3 (OR= 2.70; P < .001), dependent functional status (OR= 2.30; P < .001), CHF (OR= 3.57; P < .001), disseminated cancer (OR= 7.62; P < .001), and bleeding disorder (OR= 2.68; P < .001). Age ≥ 75, BMI < 18.5, ASA ≥ 3, functional dependence, CHF, disseminated cancer, and bleeding disorder were independently associated with eLOS. Assessing specific patient factors prior to ORIF for PHF can assist in managing perioperative risks and decreasing expenses related to eLOS. Prognosis III.

Outcomes following reverse total shoulder arthroplasty vs operative fixation for proximal humerus fractures: a systematic review and meta-analysis.

Proximal humerus fractures are common in the older population. A consensus on the optimal management of complex fractures requiring surgery has yet to be reached. A systematic review and meta-analysis was performed to compare clinical outcomes between reverse total shoulder arthroplasty (RTSA) and open reduction and internal fixation (ORIF). A systematic search of the literature was undertaken using the Medline®, PubMed, Embase™ and Cochrane Central Register of Controlled Trials databases. Prospective and retrospective studies comparing clinical and patient reported results as primary outcome measures were included in this review, with secondary outcome measures including complications and revision surgery. A meta-analysis was conducted. A total of 326 patients from 5 studies were eligible for inclusion in this review. Superior Constant-Murley scores (mean difference [MD]: 13.4, 95% confidence interval [CI]: 6.2-20.6; p<0.001), Oxford shoulder scores (MD: 4.3, 95% CI: 1.2-7.4; p=0.007), simple shoulder test scores (MD: 0.95, 95% CI: 0.01-1.89; p=0.05) and DASH (Disabilities of the Arm, Shoulder and Hand) scores (MD: 5.1 [1study], 95% CI: 2.1-8.1; p=0.034) were noted in patients receiving RTSA. Range of motion and revision surgery rates were also superior in this group. This study suggests that RTSA affords more favourable outcomes and lower revision rates than ORIF following proximal humerus fractures. Definitive conclusions are precluded, however, owing to small sample sizes and risk of bias in retrospective studies.

Biomechanical evaluation of novel intra- and extramedullary assembly fixation for proximal humerus fractures in the elderly.

Purpose: A novel intra- and extramedullary assembly fixation method was introduced, which achieved good clinical results in complex proximal humeral fractures; however, evidence of its comparability with traditional fixation is lacking. This biomechanical study aimed to compare it with traditional fixation devices in osteoporotic proximal humeral fractures. Methods: Three-part proximal humeral fractures with osteopenia were created on 12 pairs of fresh frozen humerus specimens and allocated to three groups: 1) lateral locking plate, 2) intramedullary nail, and 3) intra- and extramedullary assembly fixation. The specimens were loaded to simulate the force at 25° abduction. Thereafter, an axial stiffness test and a compound cyclic load to failure test were applied. Structural stiffness, number of cycles loaded to failure, and relative displacement values at predetermined measurement points were recorded using a testing machine and a synchronized 3D video tracking system. Results: In terms of initial stiffness and the number of cycles loaded to failure, the intra- and extramedullary assembly fixation group showed notable improvements compared to the other groups (p <0.017). The mean relative displacement value of measurement points in the intra- and extramedullary assembly fixation group was smaller than that in the other two groups. However, there was no significant difference until 10,000 cycles. The mean relative displacement of the intramedullary nail group (3.136mm) exceeded 3mm at 7,500 cycles of loading. Conclusion: In this test model, axial fixation can provide better mechanical stability than non-axial fixation. The intra- and extramedullary assembly fixation is better able to prevent the varus collapse for elderly proximal humeral fractures with posteromedial comminution.

Dual-Plate Fixation for Proximal Humerus Fractures With Unstable Medial Column in Patients With Osteoporosis.

To compare radiological and clinical outcomes between lateral locking plate (LLP) and dual-plate fixation (LLP and additional medial buttress plate) for proximal humerus fractures with medial column comminution and varus deformity in patients with osteoporosis. Retrospective. Academic medical center. Overall, 52 patients were enrolled. Of these, 26 patients underwent dual-plate fixation. The control group (LLP) was matched to the dual-plate group for age, sex, injured side, and fracture type. Patients in the dual-plate group were treated with LLP and medial buttress plate, whereas patients in the LLP group were treated with only an LLP. Demographic factors, operative time, and level of hemoglobin of the 2 groups obtained from medical records. Changes in the neck-shaft angle and the development of postoperative complications were recorded. Clinical outcomes were measured based on the visual analog scale; American Shoulder and Elbow Surgeons; Disabilities of the Arm, Shoulder, and Hand; and Constant-Murley scores. The operation time and hemoglobin loss did not differ significantly between the groups. Radiographic evaluation showed a significantly lower change in neck-shaft angle in the dual-=plate group than in the LLP group. The dual-plate group also showed better Disabilities of the Arm, Shoulder, and Hand; American Shoulder and Elbow Surgeons; and Constant-Murley scores than the LLP group. Fixation using additional medial buttress plate with LLP may be considered for treating proximal humerus fractures in patients with an unstable medial column, varus deformity, and osteoporosis. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Evaluation of effectiveness of locking compression plates in internal fixation of proximal humerus fractures: a prospective study

Introduction: Locking compression plate (LCP) provides significant biological and biomechanical advantages in the management of proximal humerus fracture (PHF) by providing greater stability, vascular preservation, superior healing, and fewer complications. However, the translation of these properties to functional benefits for patients remains to be elucidated. The objective of the study was to evaluate the effectiveness of LCP in internal fixation of PHF in terms of rate of healing and functional outcomes. Method: This prospective study enrolled 30 Proximal Humerus Fracture patients aged &gt;18 years, from both genders, and treated them with LCP. They were followed up regularly for 1 year and assessed clinically and radiologically using Neer’s criteria and Constant-Murray score. Results were analysed using Chi-square test, p≤0.05 indicated statistical significance. Result: With a mean age of 45.20±15.02 y and M:F ratio of 2.3:1, most patients showed right-sided injuries 18(60%) and Neer 4-part injuries 13(43.33%), predominantly due to road traffic accidents 19(60%), with a satisfactory Neer’s score 26(86.67%) and a good Constant-Murray score 16(53.33%). The mode of injury showed significant association with age (p=0.013) but not with gender (p=0.866). Over follow up, 27(90%) patients maintained humeral head height and 24(80%) patients showed good humeral neck-shaft angle. Radiological union of PHF took 12 weeks in 12(43.33%) of patients with no dislocation in 27(90%) of patients. However, 1(3.3%) patient showed no union. Conclusion: LCP is associated with favorable clinical, functional and radiological outcomes in PHF patients by providing rapid healing and good rigidity, angular stability, and torsional strength.

Comparative study between deltoid split approach versus delto pectoral approach for proximal humerus fracture fixation

Background: Proximal humeral fracture is defined as fractures occurring at or proximal to the surgical neck of the humerus. It affects 2.4% of women over the age of 75 years. It is the commonest fracture affecting the shoulder girdle in adults and its incidence is rising. For displaced fractures that meet surgical indications, deltopectoral approach is the most common approach for plate fixation of proximal humeral fractures. Deltoid splitting approach offers advantages of better exposure and implant placement for fixation of the fracture and early mobilization of the shoulder joint. Methods: This is a comparative study of 30 cases of proximal humerus fractures treated by surgical fixation through deltoid splitting approach and 30 cases treated by delto pectoral approach. Patient of both sexes belonging to adult age group in general population presenting with proximal humerus fracture to the orthopaedic department of Bapuji Hospital and Chigateri General hospital attached to J.J.M. Medical College, Davangere. The period of survey extends from December 2020 to December 2022. The final results were evaluated using constant Murley score periodically. This constant Murley score ranges from 0 to 100 points representing worst and shoulder function respectively. Results: No statistically significant difference was observed in outcome with regard to mechanism of injury, side of fracture and type of fracture with both deltoid splitting approach and delto pectoral approach. Conclusions: The treatment of proximal humeral fractures with a proximal locking plate is reliable using both approaches. No significant difference found in functional outcome of proximal humerus fracture following deltoid split and deltopectoral approach on serial follow up.

Plate Fixation of Proximal Humerus Fractures: How to Get It Right and Future Directions for Improvement.

Open reduction and internal fixation with locking plates (ORIF-LP) has been used for decades for the surgical management of proximal humerus fractures. Despite good outcomes have been widely published in the literature, unacceptably high rates of complications (up to 40%), many of them yielding poor outcomes and requiring reoperation (up to 25%), have also been reported, especially in elderly patients. Most common complications are related to implant failure, with intra-articular screw penetration as the most frequent and devastating. Advances in patient selection and surgical technique, and implementation of bone or cement augmentation, have been developed to hopefully decrease complication rates. Mayo-FJD Classification offers prognostic information that can aid in the decision-making process for proximal humeral fractures. Displaced valgus impacted fractures seem to be associated with well over a 10% rate of avascular necrosis after ORIF-LP. A principle-based and stepwise surgical technique combining anatomic reduction and a short screw configuration can provide good outcome in most patients, even the elderly, decreasing implant failures to less than 10%. Acrylic cement augmentation has the potential to further decrease implant failure rate to 1%. Reoperation rates are higher partly due to the need to remove hardware for painful subacromial conflict. However, no studies to date definitively demonstrated the superiority of ORIF-LP compared to non-operative treatment, intramedullary nailing, or reverse shoulder arthroplasty. ORIF-LP can provide good results for the surgical management of displaced proximal humerus fractures even in elderly patients provided adequate patient selection and a principle based and stepwise surgical technique, supplemented with bone graft or acrylic cement when needed. Poor outcomes and high complication and reoperation rates should be expected when these recommendations are not followed.

Fibular Autograft as Medial Support with Proximal Humerus Locking Plate Construct in Comminuted Proximal Humerus Fractures: A Retrospective Analysis.

Varus collapse is one of the pivotal mechanisms of failure following surgical fixation of proximal humerus fractures. The aim of the present study was to evaluate functional and radiological outcomes of non-vascularized fibular autograft as medial support with locking plate construct for comminuted proximal humerus fractures (PHF's). We retrospectively evaluated 18 patients with unstable PHF's in the age group 50-70years with a minimum follow-up of two years. All thefracture patterns were classified according to Resch, Neer's and AO classification and either medial calcar compromise or comminution were present in all. Open reduction internal fixation (ORIF) with a locking plate was performed for all thepatients along with intramedullary fibular autograft to support medial calcar. Radiological outcome was assessed by neck-shaft angle (NSA) graded according to the Paavolainen grading method and difference in thehumeral head height (HHH). Functional outcome was assessed by shoulder range of motion (ROM), University of California-Los Angeles (UCLA) score and American shoulder and elbow surgeons score (ASES). Radiological union at the fracture site was achieved in all the patients at mean of 8months (range 6-12months). Range of movements were mean flexion of 123.89, extension 35.28, internal rotation 66.94, external rotation 57.78 and abduction of 115° at final follow-up. The average NSA was in the range of 120°-130° and none of the patients showed difference in HHH of ≥ 4mm in the immediate post-operative radiograph and that taken on final follow-up. The functional outcome assessed by ASES score (mean 89.44) and UCLA score (mean 29.61) suggested fair to good results. None of the patients has shown varus collapse and avascular necrosis. Neither there were any complications related to the donor area. In unstable proximal humerus fractures with calcar comminution or void, PHILOS plate fixation augmented with fibular autograft as a medialsupport reduces varus collapse and promotes early radiological union.
