Short-term complication rates of open reduction and plate fixation and intramedullary nailing in the treatment of humeral shaft fractures: a propensity score matched analysis.

INTRODUCTION: This is a retrospective cohort study designed to compare short-term postoperative complication rates between closed humeral shaft fractures treated by open reduction and internal fixation (ORIF) versus intramedullary nailing (IMN), as well as secondary independent risk factors for adverse outcomes. MATERIALS AND METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried using CPT codes to identify patients that underwent an open reduction and plate fixation or intramedullary nailing procedure for a closed humeral shaft fracture from 2010 to 2021. Cohorts were matched using propensity scores to account for demographic differences and rates of complications were compared between the two groups. RESULTS: From the database, a total of 4,222 patients were identified who met inclusion criteria, with 3,326 and 896 undergoing ORIF and IMN respectively. After propensity score matching, 866 of the nearest-neighbor matches were included in each cohort for a total of 1,732 patients in the final analysis. The rate of any adverse event (AAE) was significantly higher in the ORIF cohort (16.3%) than the IMN cohort (12.1%, p = 0.01). The ORIF group had higher rates of postoperative transfusion (p = 0.002), return to OR (p = 0.005), and surgical site infection (SSI, p = 0.03). After multivariate analysis, ASA class 4, increasing age, increasing operative time, and history of bleeding disorder were found to increase the risk of AAE in both ORIF and IMN patients. CONCLUSIONS: While prior studies have claimed higher complication rates in IMN patients, this study found a significantly higher short-term risk of AAE in ORIF patients when compared in matched cohorts. However, individual 30-day complication rates do not differ significantly between procedures, and both have been shown to be safe and effective tools in the management of humeral shaft fractures.

Risk factors and incidence of short-term complications following open reduction and internal fixation of scapula fractures.

PURPOSE: To determine the short-term complication rates following open reduction and internal fixation of scapula fractures, factors affecting the development of adverse events, and complication rates based on the anatomic location of the fracture. METHODS: Thirty-day complication rates for patients who underwent open reduction and internal fixation of the scapula were compared between glenoid, body, coracoid, and acromion fracture locations, as identified by International Classification of Disease codes. Possible adverse events included postoperative surgical site infection, renal insufficiency, intubation, pneumonia, deep vein thrombosis, pulmonary embolism, urinary tract infection, wound dehiscence, stroke, and blood transfusion. RESULTS: A total of 251 scapula fractures were identified, with 161 having known fracture locations: 105 glenoid, 20 body, 9 coracoid, and 27 acromial fractures. The rate of any adverse event for all scapular fractures was 2.0%, with no significant difference between anatomic locations (p = 0.79). The overall rates of transfusion, surgical site infection, and return to OR were 0.4%, 0.8%, and 3.98%. Steroid use associated with a significantly increased risk of any adverse event (OR: 55.57, p = 0.038) and outpatient status demonstrated a protective effect on reoperation (OR: 0.11, p = 0.014). There were no significant differences in the rates between groups [transfusion (p = 0.91); surgical site infection (p = 0.17); reoperation (p = 0.85)]. CONCLUSION: Complication rates within thirty days of ORIF for scapula fracture were low. Reoperation was the most common complication, followed by surgical site infection, wound dehiscence, stroke, transfusion, and pneumonia. Steroid use was a risk factor for developing any adverse event, and outpatient status was protective against reoperation. The 30-day complication profile of glenoid, body, coracoid, and acromial fractures was not significantly different. The low complication rates support the relative short-term safety of operative intervention with internal fixation. LEVEL OF EVIDENCE: Level III.

Risk factors for adverse events after clavicle fracture open reduction and internal fixation: A NSQIP study.

BACKGROUND: Midshaft clavicle fractures are often subject to increased complications when treated nonoperatively, so surgical treatment with open reduction and internal fixation (ORIF) is a favored alternative. Despite safer outcomes, adverse events such as surgical site infections may still persist, particularly in the presence of certain patient characteristics. The objective of this study was to determine risk factors for and the frequency of adverse events following ORIF for clavicle fractures. METHODS: A retrospective review of the National Surgical Quality Improvement Program (NSQIP) database from 2012 to 2021 identified patients undergoing isolated ORIF for clavicle fractures. Patient demographics and 30-day complications were collected. Bivariate analyses with a student's t-test or chi-square test were used to identify possible predictor variables for either AAE or SSI, and demographic metrics with P < 0.2 were included in a multivariable regression model. Multivariable analyses identified significant independent patient risk factors for any adverse event (AAE) or SSI within 30-days of surgery. Adjusted odds ratios were reported for each variable included in the model. Statistical significance was set a prior at P < 0.05. RESULTS: The 6,753 selected patients who underwent ORIF for clavicle fractures between 2012 and 2021 were 38.1 ± 15.3 years of age, BMI 26.2 ± 4.9 kg m-12, and 77.3 % male. Of this cohort, 88.4 % received treatment on an outpatient basis. Postoperative adverse events were experienced by 128 (1.9 %) patients within 30 days of surgery, and SSI were prevalent in 0.77 % of patients, followed by wound dehiscence in 0.12 % of patients. After controlling for patient demographics and comorbidities, notable risk factors for adverse events included current smoking status (OR=2.036; P < 0.001) and patient age (OR=1.025; P < 0.001). Outpatient status (OR=0.528; P = 0.004) was protective. CONCLUSION: The present study noted significantly increased risk of postoperative adverse events in older patients, as well as patients who smoke. Outpatient setting was significantly protective for adverse events. These findings help to provide further clinical context to guide surgical decision making and inform surgeons on current risks and outcomes.

Total Elbow Arthroplasty Versus Open Reduction and Internal Fixation for Distal Humerus Fractures: A Propensity Score Matched Analysis of 30-Day Postoperative Complications.

Introduction: Open reduction and internal fixation (ORIF) is an established surgical procedure for distal humeral fractures; however, total elbow arthroplasty (TEA) has become an increasingly popular alternative for elderly patients with these injuries. Using a large sample of recent patient data, this study compares the rates of short-term complications between ORIF and TEA and evaluates complication risk factors. Methods: Patients who underwent primary TEA or ORIF from 2012 to 2021 were identified by Current Procedural Terminology codes in the American College of Surgeons National Surgical Quality Improvement Program database. Propensity score matching controlled for demographic and comorbid differences. The rates of 30-day postoperative complications were compared. Results: A total of 1539 patients were identified, with 1365 (88.7%) and 174 (11.3%) undergoing ORIF and TEA, respectively. Patients undergoing TEA were older on average (ORIF: 56.2 ± 19.8 years, TEA: 74.3 ± 11.0 years, P < .001). 348 patients were included in the matched analysis, with 174 patients in each group. TEA was associated with an increased risk for postoperative transfusion (OR = 6.808, 95% CI = 1.355 - 34.199, P = .020). There were no significant differences in any adverse event (AAE) between procedures (P = .259). A multivariate analysis indicated age was the only independent risk factor for the development of AAE across both groups (OR = 1.068, 95% CI = 1.011 - 1.128, P = .018). Conclusion: The risk of short-term complications within 30-days of ORIF or TEA procedures are similar when patient characteristics are controlled. TEA, however, was found to increase the risk of postoperative transfusions. Risks associated with increasing patient age should be considered prior to either procedure. These findings suggest that long-term functional outcomes can be prioritized in the management of distal humerus fractures.

Anatomic Shoulder Arthroplasty in the Setting of Concurrent or Prior Rotator Cuff Repair: A Systematic Review.

Background: Reverse total shoulder arthroplasty (RSA) is the gold standard in management of osteoarthritis (OA) in the setting of rotator cuff pathology. However, there are significant complications associated with the procedure. An alternative option in the setting of a deficient rotator cuff may be to perform a repair prior to or concurrently with an anatomic total shoulder arthroplasty (aTSA). Methods: A systematic review was performed utilizing Preferred Reporting Items for Systematic Meta-Analyses (PRISMA) guidelines to evaluate outcomes in aTSA with concomitant or prior rotator cuff repair (RCR). Key outcomes were complication rate and subjective outcome scores. Results: Seven studies were included in the review. One study found a higher rate of total adverse events in the prior repair group (17% vs 7%, P = .01) while others found no significant difference. There was a nonstatistically significant increase in revision rates among patients with larger tears at time of repair. Prior repair groups were associated with a higher rate of re-tear in one study (13% vs 1%, P = .014). Concomitant repair was associated with a higher rate of loosening. In patients with prior repair, there was no statistical difference in strength, range of motion (ROM), simple shoulder test (SST), Single Assessment Numeric Evaluation (SANE), American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), and visual analogue scale (VAS). In patients with concurrent repair, one study demonstrated a less drastic improvement in Hospital for Special Surgery (HSS) in "moderate" repairs as opposed to "good" repairs. Conclusions: Anatomic TSA is an appropriate treatment for glenohumeral OA in patients with a prior successful RCR and in younger patients with concurrent repair of small or medium tears. Level of Evidence: Level III.

Conversion of Total Shoulder Arthroplasty to Reverse Total Shoulder Arthroplasty: Time to Conversion and Indications at a Tertiary Care Center.

Anatomic total shoulder arthroplasty (aTSA) and reverse shoulder arthroplasty (RSA) are increasingly common, with volume projected to increase over 90% by the year 2025. Therefore, it is critical to understand the expected longevity of aTSA using modern implants and techniques, rates of conversion to RSA, and most common indications for conversion if surgeons are to properly diagnose and treat patients. A retrospective review was conducted of 800 patients who had undergone aTSA, RSA, or hemiarthroplasty (HA) between 2015 and 2019 at a tertiary-care academic medical center. All patients who had undergone primary aTSA were included. Patients who had undergone primary HA, primary RSA, or had had primary surgery at an outside hospital were excluded. Primary outcomes were indications for and time to conversion from aTSA to RSA. Secondary outcomes were indications for primary aTSA and preliminary survivorship data of modern implants. Between 2015 and 2019, 235 patients underwent primary aTSA, with a mean time to follow-up of 3.43 years (0.07-5.24 years). Mean time to conversion from aTSA to RSA was 15.6 months, with a 2.13% conversion rate (5 patients). Eighty percent of the conversions (4 patients) were due to rotator cuff tear. We found that 2.13% of primary aTSA patients at our institution were converted to RSA at a mean of 15.6 months after the primary procedure. Rotator cuff tears were the indication for 80% of these. Since conversions occurred relatively soon after primary surgery, the authors recommend use of MRI without contrast prior to surgery to possibly reduce the risk of such failures. This study was a Level 3 retrospective database review.

Implantable Subacromial Balloon Spacers in Patients With Massive Irreparable Rotator Cuff Tears: A Systematic Review of Clinical, Biomechanical, and Financial Implications.

PURPOSE: To determine the clinical, biomechanical, and financial impact of the use of subacromial balloon spacers in the surgical management of massive, irreparable rotator cuff tears (RCTs). METHODS: All studies assessing the use of implantable subacromial balloon spacers for management of massive, irreparable RCTs were systematically searched. Risk of bias was assessed using Methodological Index for Non-Randomized Studies criteria. Data extraction and analysis was performed for pain and function scores, shoulder range of motion (ROM), glenohumeral contact pressure and vertical migration of humeral head, and cost. Subjective synthesis was performed with forest plots when outcomes were reported in 3 or more studies. RESULTS: In total, 19 studies met inclusion criteria for analysis; 337 patients (mean age 68 years) had 343 subacromial balloon spacer implantations. Throughout a mean follow-up of 33 months, there was significant improvement in the Total Constant Score (preoperative: 22.5-41.8; postoperative: 51.4-72.3), Oxford Shoulder Score (preoperative: 21.3-26; postoperative: 34.39-48.2), American Shoulder and Elbow Surgeons score (preoperative: 24.5-59.1; postoperative: 72.5-85.7), and shoulder ROM parameters. Subacromial balloon spacer placement resisted superior humeral head migration (range of preoperative to postoperative difference: 2.8-6.2 mm) and decreased peak subacromial pressure during shoulder ROM. CONCLUSIONS: Existing literature of subacromial balloon spacers has a high risk of bias, lack of appropriate control, and low levels of evidence. A qualitative synthesis indicates that subacromial balloon spacer implantation in patients with massive irreparable RCTs is cost-effective and leads to improved function (Total Constant Score and Oxford Shoulder Score) and ROM. In cadaveric studies, subacromial balloon spacers resist superior humeral head migration and reduce subacromial pressure. The theoretical risk of biodegradation of the balloon spacer has not been substantiated in study of up to 5-years follow-up, and the risk of complications from this procedure appears to be minimal. LEVEL OF EVIDENCE: IV; Systematic review of level III-IV studies.

Shoulder: what the orthopaedic doctor needs to know.

Diagnosing shoulder pathology accurately requires both clinical expertise and the ability to interpret and correlate radiographic studies. Variational anatomy of the shoulder combined with the complexity of physical examination makes this difficult. Physical examination of the shoulder often leaves the surgeon with more than one working diagnosis. Imaging studies of the shoulder are more valuable if used to confirm a working diagnosis as opposed to reading the study in a vacuum. Clinical correlation should also be considered for any and all findings on an imaging study. Collaboration of the surgeon and the radiologist is essential in reducing the number of over-reported findings that are clinically insignificant. The surgeon should directly communicate with the radiologist as to his or her working diagnosis and the goal of the study. In this way the surgeon and radiologist become superior diagnosticians.
