The contribution of reverse shoulder arthroplasty to utilization of primary shoulder arthroplasty.

ABSTRACT: BACKGROUND:We assessed the contribution of reverse shoulder arthroplasty to overall utilization of primary shoulder arthroplasty and present age- and sex-stratified national rates of shoulder arthroplasty. We also assessed contemporary complication rates, mortality rates, and indications for shoulder arthroplasty, as well as estimates and indications for revision arthroplasty. METHODS:We used the Nationwide Inpatient Samples for 2009 through 2011 to calculate estimates of shoulder arthroplasty and assessed trends using Joinpoint (National Cancer Institute, Bethesda, MD) regression. RESULTS:The cumulative estimated utilization of primary shoulder arthroplasty (anatomic total shoulder arthroplasty, hemiarthroplasty, and reverse shoulder arthroplasty) increased significantly from 52,397 procedures (95% confidence interval [CI], 47,093-57,701) in 2009 to 67,184 cases (95% CI, 60,638-73,731) in 2011. Reverse shoulder arthroplasty accounted for 42% of all primary shoulder arthroplasty procedures in 2011. The concomitant diagnosis of osteoarthritis and rotator cuff impairment was found in only 29.8% of reverse shoulder arthroplasty cases. The highest rate of reverse shoulder arthroplasty was in the 75- to 84-year-old female subgroup (77 per 100,000 persons; 95% CI, 67-87). Revision cases comprised 8.8% and 8.2% of all shoulder arthroplasties in 2009 and 2011, respectively, and 35% of revision cases were because of mechanical complications/loosening whereas 18% were because of dislocation. CONCLUSIONS:The utilization of primary shoulder arthroplasty significantly increased in just a 3-year time span, with a major contribution from reverse shoulder arthroplasty in 2011. Indications appear to have expanded because a large percentage of patients did not have rotator cuff pathology. The burden from revision arthroplasties was also substantial, and efforts to optimize outcomes and longevity of primary shoulder arthroplasty are needed.

Project description:Hypothesis and backgroundThere is no differences in abduction, internal rotation, or external rotation strength after reverse total shoulder arthroplasty (rTSA) with or without subscapularis repair. Repair of the subscapularis can be effective in the setting of rTSA. However, consensus has yet to be reached on whether postoperative strength after rTSA differs based on subscapularis management. The purpose of this review is to evaluate shoulder strength outcomes after rTSA with and without subscapularis tendon repair.MethodsA comprehensive literature review was conducted using the key terms "subscapularis" AND "reverse total shoulder arthroplasty" AND "muscle strength" in PubMed, Embase, Web of Science, Cochrane Reviews and Trials, and Scopus. Original, English-language studies evaluating shoulder strength outcomes after rTSA published from January 1, 2000, to present were evaluated. Strength outcomes reported included abduction strength (kg) and internal rotation strength (kg) using an electric spring balance and external rotation strength (lb) using a handheld dynamometer. Heterogeneity of data in the included studies did not allow for meta-analysis.ResutsThe search yielded 4253 unique results, which were screened for inclusion according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Two articles met eligibility criteria and were included in the final full-text review. A total of 267 shoulders were represented, 111 with subscapularis repair and 156 without subscapularis repair. No significant differences in abduction (P = .39), internal rotation (P = .09), and external rotation (P = .463) strength were observed between subscapularis repair and nonrepair groups.ConclusionThere were no differences in abduction, internal rotation, or external rotation strength after rTSA with or without subscapularis repair. The literature on postoperative strength outcomes after rTSA is limited, and further study in this area is warranted.
