Infection following mini-open rotator cuff repair: a single surgeon experience.

BACKGROUND: Surgical technique has been shown to influence risk of surgical site infection following rotator cuff repair (RCR). Few studies have reported the rate of infection associated with mini-open RCR. The goal of this study was to report the postoperative infection rate and risk factors for infection among patients undergoing RCR performed by a single surgeon using a modified mini-open technique. Our hypothesis was that the rate of infection after mini-open RCR would be lower than previously reported for this surgical approach. METHODS: We retrospectively reviewed an institutional shoulder surgery database to identify patients who underwent mini-open RCR performed by one surgeon at an academic tertiary care institution between 2003 and 2020. Patient records were reviewed to determine which individuals returned within 3 months postoperatively with a superficial or deep surgical site infection requiring operative management. Patient demographics, preoperative clinical characteristics, intraoperative variables, microbiological findings, infection management, and clinical course after infection were recorded. Backward elimination multivariate regression was used to assess for significant risk factors for infection. RESULTS: Of the 925 patients identified, 823 (89%) had at least 3 months of follow-up and were included for further analysis. A majority of the patients undergoing RCR were men (57%). The mean age was 58.4 ± 9.9 years, and the mean body mass index was 29.3 ± 5.9 kg/m2. Fourteen cases (1.7%) of postoperative surgical site infection were identified in 13 patients. Ten infections (1.2%) were superficial and 4 (0.49%) were deep. The most commonly identified organisms were Staphylococcus aureus and Cutibacterium acnes. Male sex (odds ratio [OR] 4.3, 95% CI 1.2-15.3) and diabetes mellitus (OR 3.9, 95% CI 1.2-12.6) were found to be associated with greater risk of infection. The RCR construct was found to be intact in all 10 patients with superficial infections and 2 of the 4 patients with deep infections. All infections were successfully treated with 1 round of surgical débridement and wound irrigation, and with 6 or fewer weeks of intravenous antibiotic therapy. All patients with postoperative infections recovered with no sequelae at a median final follow-up of 63.5 months (range, 3-215 months). CONCLUSIONS: This single-surgeon series of a large patient cohort undergoing mini-open RCR over an 18-year period demonstrated a low overall infection rate of 1.7%. Only 4 infections were deep, which suggests that deep infection after mini-open RCR is uncommon and approximates infection rates seen with arthroscopic techniques.

Predicting Risk of 30-day Postoperative Morbidity Using the Pathologic Fracture Mortality Index.

INTRODUCTION: The purpose of this study was to evaluate the ability of the Pathologic Fracture Mortality Index (PFMI) to predict the risk of 30-day morbidity after pathologic fracture fixation and compare its efficacy with those of the American Society of Anesthesiologists (ASA) physical status, modified Charlson Comorbidity Index (mCCI), and modified frailty index (mFI-5). METHODS: Cohorts of 1,723 patients in the American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2020 and 159 patients from a tertiary cancer referral center who underwent fixation for impending or completed pathologic fractures of long bones were retrospectively analyzed. National Surgical Quality Improvement Program morbidity variables were categorized into medical, surgical, utilization, and all-cause. PFMI, ASA, mCCI, and mFI-5 scores were calculated for each patient. Area under the curve (AUC) was used to compare efficacies. RESULTS: AUCs predicting all-cause morbidity were 0.62, 0.54, and 0.56 for the PFMI, ASA, and mFI-5, respectively. The PFMI outperformed the ASA and mFI-5 in predicting all-cause ( P < 0.01), medical ( P = 0.01), and utilization ( P < 0.01) morbidities. In the 2005 to 2012 subset, the PFMI outperformed the ASA, mFI-5, and mCCI in predicting all-cause ( P = 0.01), medical ( P = 0.03), and surgical ( P = 0.05) morbidities but performed similarly to utilization morbidity ( P = 0.19). In our institutional cohort, the AUC for the PFMI in morbidity stratification was 0.68. The PFMI was associated with all-cause (odds ratio [OR], 1.30; 95% confidence interval [CI], 1.12 to 1.51; P < 0.001), medical (OR, 1.19; 95% CI, 1.03 to 1.40; P = 0.046), and utilization (OR, 1.32; 95% CI, 1.14 to 1.52; P < 0.001) morbidities but not significantly associated with surgical morbidity (OR, 1.21; 95% CI, 0.98 to 1.49; P = 0.08) in this cohort. DISCUSSION: The PFMI is an advancement in postoperative morbidity risk stratification of patients with pathologic fracture from metastatic disease. LEVEL OF EVIDENCE: III.

Use of custom glenoid components for reverse total shoulder arthroplasty.

BACKGROUND: Our purpose was to evaluate a custom reverse total shoulder arthroplasty glenoid baseplate for severe glenoid deficiency, emphasizing the challenges with this approach, including short-term clinical and radiographic outcomes and complications. METHODS: This was a single-institution, retrospective series of 29 patients between January 2017 and December 2022 for whom a custom glenoid component was created for extensive glenoid bone loss. Patients were evaluated preoperatively and at intervals for up to 5 years. All received preoperative physical examinations, plain radiographs, and computed tomography (CT). Intra- and postoperative complications are reported. RESULTS: Of 29 patients, delays resulted in only undergoing surgery, and in three of those, the implant did not match the glenoid. For those three, the time from CT scan to implantation averaged 7.6 months (range, 6.1-10.7 months), compared with 5.5 months (range, 2-8.6 months) for those whose implants fit. In patients with at least 2-year follow-up (n=9), no failures occurred. Significant improvements were observed in all patient-reported outcome measures in those nine patients (American Shoulder and Elbow Score, P<0.01; Simple Shoulder Test, P=0.02; Single Assessment Numeric Evaluation, P<0.01; Western Ontario Osteoarthritis of the Shoulder Index, P<0.01). Range of motion improved for forward flexion and abduction (P=0.03 for both) and internal rotation up the back (P=0.02). Pain and satisfaction also improved (P<0.01 for both). CONCLUSIONS: Prolonged time (>6 months) from CT scan to device implantation resulted in bone loss that rendered the implants unusable. Satisfactory short-term radiographic and clinical follow-up can be achieved with a well-fitting device. Level of evidence: III.

Assessing the Impact of COVID-19 on the 2021 Orthopaedic Surgery Match Outcomes.

The purpose of this study was to assess the influence of the COVID-19 pandemic on the 2021 orthopaedic surgery residency match outcomes. Because in-person away rotations and interviews were canceled during the 2020 to 2021 application cycle, we hypothesized that applicants would match at their home program at a higher rate in 2021 than in previous years. Methods: We queried allopathic orthopaedic surgery residency websites and social media accounts for names of residents and medical school information for cohorts matching from 2017 through 2021. To assess availability of and participation in virtual away rotations, we administered a survey to Accreditation Council for Graduate Medical Education-accredited allopathic orthopaedic surgery residency programs. The primary outcome was the annual proportion of applicants matching at the program affiliated with their medical school ("home program"). Subgroup analyses were stratified by Doximity reputation ranking and availability of a virtual away rotation. Results: We identified 2,632 residents who matched between 2017 and 2020 and 698 residents who matched in 2021. Overall home program match rate and likelihood of home matching were higher in 2021 compared with 2017 to 2020 (28% vs. 20%; odds ratio [OR] = 1.51, 95% confidence interval [CI] 1.24-1.82, p < 0.001). The increase in the home match rate at programs ranked in the top 30 (27% vs. 20%, p = 0.034) was similar to the increase at programs ranked outside the top 30 (28% vs. 20%, p < 0.001). Of the 66 (48%) programs that responded to the survey, 16 (24%) offered a virtual away rotation. Programs with a higher Doximity ranking were more likely than lower-ranked programs to offer a virtual away rotation (OR = 6.75, 95% CI 1.95-23.4, p = 0.003). Home match rates did not differ significantly between programs that offered a virtual away rotation and those that did not (26% vs. 32%, p = 0.271). Conclusions: A higher proportion of orthopaedic surgery residency applicants matched at their home program in 2021 compared with previous years. Limitations on in-person activities due to the COVID-19 pandemic may have contributed to this rise. Level of Evidence: N/A.
