Background Reverse total shoulder arthroplasty (RTSA) has become an increasingly popular surgery for patients with rotator cuff arthropathy, unreconstructible proximal humeral fracture, and end-stage glenohumeral arthritis. The increased annual volume of RTSAs has resulted in more postoperative complications and revision rates between 3.3% and 10.1%. Postoperative infection is one of the most common complications requiring revision surgery after primary RTSA. This study assesses patient-specific risk factors for development of early infection after primary RTSA in a single high-volume shoulder arthroplasty institution. Methods From 2014 to 2019, 902 consecutive primary RTSAs were performed for surgical treatment of rotator cuff arthropathy, glenohumeral arthritis, inflammatory arthropathy, and/or dislocation. Excluding proximal humeral or scapula fractures, 756 cases met the inclusion criteria and had a minimum of 3-month follow-up. All surgeries were performed using the same surgical technique and received similar antibiotic prophylaxis. Age, patient demographics, medical history, smoking history, and prior ipsilateral shoulder treatment and/or surgery were recorded. Multivariable logistic regression analysis was used to determine risk factors associated with development of postoperative shoulder infection. Results Thirty-five patients did not meet minimum follow-up criteria and were lost to follow-up. Overall, of 721, 22 patients (3%) developed a postoperative ipsilateral shoulder infection. Previous nonarthroplasty surgery and history of rheumatoid arthritis were significantly associated with the development of postoperative shoulder infection. Amongst 196 patients who had previous nonarthroplasty shoulder surgery, there were 12 postoperative shoulder infections (6%) compared with those without previous shoulder surgery (10 of 525, 2%) ( P = .003). Among 58 patients with rheumatoid arthritis, there were 5 postoperative shoulder infections (9%) compared with patients without rheumatoid arthritis (17 of 663, 3%) ( P = .010). Patient age, gender, smoking status, history of diabetes mellitus, history of cancer/immunosuppression, and prior cortisone injection did not demonstrate significant associations with the development of postoperative infection. Conclusion Prior nonarthroplasty shoulder surgery and/or rheumatoid arthritis are independently associated with the development of postoperative infection after primary RTSA. Patients who demonstrate these risk factors should be appropriately evaluated and preoperatively counseled before undergoing primary RTSA. Strong consideration should be given to avoid minimally invasive nonarthroplasty surgery as a temporizing measure to delay definitive RTSA.
Case: A 68-year-old male, status post revision right reverse total shoulder arthroplasty (RTSA) for periprosthetic fracture, suffered a periprosthetic joint infection necessitating 2-stage revision. Imaging revealed 8.6 cm of ipsilateral proximal humeral bone loss (PHBL) including loss of the greater and lesser tuberosities. A 2-stage revision was performed using an antibiotic spacer, followed by a custom long-stem RTSA for definitive reconstruction. Two years postoperatively, the patient had significantly improved pain and functional range of motion. Conclusion: Custom long-stem RTSA could serve as a potentially viable reconstructive option in patients with severe PHBL.
Introduction:Hip fractures are common injuries that are associated with serious morbidity/mortality in the elderly and represent a substantial financial burden to healthcare systems. Previous studies demonstrated that resident involvement in orthopaedic surgeries is associated with increased surgical time and cost, with equivocal or worse outcomes. This study evaluated outcomes of hip fracture surgery at one institution, before and after the introduction of an orthopaedic residency program.Methods:A retrospective chart review divided patients who underwent hip fracture surgery between January 2015 and January 2018 into two groups based on resident involvement. Outcomes including surgical time, length of stay (LOS), readmission rate, and direct/indirect costs were compared as were the American Society of Anesthesiologists physical status score and procedure conducted.Results:Six hundred sixty-two hip fracture surgeries were performed in 36 months. Residents were engaged in 303 cases (45.8%) with no notable differences in the two groups regarding American Society of Anesthesiologists score, procedure conducted, or readmission rate. With resident involvement, surgical time was significantly longer (91.2 versus 78.9 minutes, P-value = 0.004), whereas LOS was significantly shorter (5.2 versus 5.6 days, P-value = 0.003). Finally, there were significant reductions in direct costs (8% reduction; P < 0.001) and OR implant costs (12% reduction; P < 0.001), but significant increase in indirect costs (7% increase; P < 0.001).Discussion:Surgical experience is critical in orthopaedic training. There are concerns regarding potential negative effects of resident involvement on surgical outcomes and healthcare costs. While resident involvement was associated with slightly increased surgical times and indirect costs, it also led to decreased LOS and direct costs. We believe this is the first study to compare patient outcomes at one institution before and after resident involvement. Our findings demonstrated, compared with attendings alone, resident involvement resulted in an overall improvement rather than compromise in patient care.
