Simultaneous bilateral shoulder arthroplasty: a case series.
Journal of shoulder and elbow surgery
BACKGROUND: Staged bilateral shoulder arthroplasty procedures have been shown to have good functional outcomes. The next step is to explore the option of simultaneous bilateral shoulder arthroplasty (SBSA). We report on the first case series of SBSA in the United States. The purpose of this study was to examine the safety and postoperative complication profile of SBSA and provide a technique reference for surgeons considering performing or investigating this procedure.
METHODS: We conducted a retrospective record review of all the SBSA procedures performed by the senior author between 2007 and 2020. Patient demographic characteristics, surgical information, and postoperative data were collected. Data were compiled, and means, standard deviations, and ranges were calculated. Any readmissions or postoperative complications requiring revision were noted. A cohort of patients matched for age, sex, and body mass index with staged (sequential) bilateral total shoulder arthroplasty was analyzed for comparison.
RESULTS: Thirteen patients were identified in the simultaneous group (SBSA). The mean age was 64 ± 15 years, with 9 women (69%) and 4 men (31%); the mean body mass index was 29.1 ± 7.5. The mean American Society of Anesthesiologists score was 2.55 ± 0.7, average blood loss was 364 ± 170 mL (range, 50-600 mL), 5 of 13 patients (38%) underwent blood transfusions, and the mean surgical time was 183 ± 42 minutes. Postoperatively, the mean visual analog scale pain score on postoperative day 1 was 4 ± 2 (range, 0-7), and the mean length of stay was 3.3 days. Postoperative complications included urinary tract infections in 2 patients, urinary retention in 2 patients, and recurrence of paroxysmal atrial fibrillation in 1 patient. No patient was readmitted within 90 days of surgery. One patient underwent a reoperation 2 years postoperatively for symptomatic hardware removal (cerclage cables around the tuberosities). A matched cohort of staged bilateral total shoulder arthroplasty patients was analyzed for comparison. Postoperative complications in the staged group included 1 reverse total shoulder arthroplasty patient with subjective instability that was managed with additional physical therapy. There were no documented readmissions within 90 days or revision arthroplasty procedures in either cohort.
CONCLUSIONS: SBSA is a reasonable procedure that can be useful in select patients, with promising short-term safety noted in this series. Prospective randomized studies are needed to assess the long-term safety and efficacy of the procedure.
