RESUMO
INTRODUCTION: Stemless reverse total shoulder arthroplasty is used to treat rotator cuff deficient arthropathies, rheumatoid arthritis, and osteoarthritis. It has several advantages over the stemmed implant including preservation of bone stock, reduced surgical time, and easier revision. METHODS: A systematic search was conducted in MEDLINE, EMBASE, PubMed, and CENTRAL to retrieve all relevant studies evaluating stemless reverse total shoulder arthroplasty. RESULTS: The literature search identified 1993 studies out of which 7 studies were included in this review; 324 patients underwent stemless reverse total shoulder arthroplasty with a weighted mean age of 74.1 (SD = 8.6, range = 38 to 93) years and a weighted mean follow-up time of 44 (SD = 6.6, range = 3 to 95) months. The included studies reported significant improvements in range of motion and functional scores comparable to stemmed reverse total shoulder arthroplasty. The weight mean flexion and abduction was (135 ± 12)° and (131 ± 12)° post-operatively, respectively. The weighted mean constant score increased from (26.7 ± 5.2) Patients (pts) to (63.0 ± 8.0) pts post-operatively. Overall complication and revision rate were 12.3% and 5.2%. CONCLUSION: Early and mid-term results indicate stemless reverse total shoulder arthroplasty has similar clinical outcomes to stemmed reverse total shoulder arthroplasty. There was no radiological evidence of humeral loosening at the latest follow-up.
RESUMO
BACKGROUND: Facioscapulohumeral muscular dystrophy (FSHD) is a rare condition associated with selective weakness of the muscles of the upper arm, face, and shoulder girdle, negatively affecting daily activities. Scapulothoracic arthrodesis may restore shoulder function and improve quality of life. The purpose of this review is to evaluate the outcomes and complications of scapulothoracic arthrodesis in FSHD patients. METHODS: Medline, Pubmed, and Embase were systematically searched. Studies were included if they described scapulothoracic arthrodesis in FSHD with follow-up, and outcomes were adequately reported. Thirteen eligible articles reported the outcomes of 199 arthrodesis in 130 patients. RESULTS: The mean gain of shoulder forward elevation and abduction were 45° (p < 0.05) and 40° (p < 0.05), respectively. There was an overall cosmetic satisfaction and improved performance of daily activities. There is limited and heterogeneous data on changes in pulmonary function, but such changes are clinically insignificant. The rate of complications was 41% of which 10% were serious, requiring an intervention or re-admission. The most common complications were hardware failure (8%), non-union (6%), and pneumothorax (5%). DISCUSSION: Scapulothoracic arthrodesis improved cosmesis, performance of daily activities and shoulder motion with no clinically significant loss of pulmonary function. The complication rate is high, and some are potentially serious.
RESUMO
BACKGROUND: Stemless anatomic total shoulder arthroplasty (TSA) is used in the treatment of osteoarthritis of the shoulder joint and other degenerative shoulder diseases. It has several proposed advantages over stemmed TSA including increased bone preservation, decreased operative time, and easier removal at revision. METHODS: A systematic search was conducted using MEDLINE, Embase, PubMed, and CENTRAL (Cochrane Central Register of Controlled Trials) to retrieve all relevant studies. RESULTS: The literature search yielded 1417 studies, of which 22 were included in this review, with 962 patients undergoing stemless TSA. Stemless TSA led to significant improvements in range of motion and functional scores in all included studies. Meta-analysis of comparative studies between stemless and stemmed TSA identified no significant differences in postoperative Constant scores (mean difference [MD], 1.26; 95% confidence interval [CI], -3.29 to 5.81 points; P = .59) or complication rates (odds ratio, 1.79; 95% CI, 0.71-4.54; P = .22). Stemless TSA resulted in a significantly shorter operative time compared with stemmed TSA (MD, -15.03 minutes; 95% CI, -23.79 to -6.26 minutes; P = .0008). Stemless TSA also resulted in significantly decreased intraoperative blood loss compared with stemmed TSA (MD, -96.95 mL; 95% CI, -148.53 to -45.36 mL; P = .0002). CONCLUSION: Stemless anatomic TSA resulted in similar functional outcomes and complication rates to stemmed TSA with decreased operative time and lower blood loss. Further research is required to investigate the long-term durability of the stemless implant.
