| Popis: | Background Reverse shoulder arthroplasty (RSA) designs vary in the lateralization and distalization geometry, which may affect functional outcomes. The purpose was to determine the effect of RSA lateralization and distalization on final functional outcomes by using the “lateralization shoulder angle” (LSA) and the “distalization shoulder angle” (DSA). Methods Forty-six consecutive patients who underwent RSA for cuff tear arthropathy were retrospectively evaluated. Functional outcome and radiographs were evaluated at a minimum of 2 years postoperatively and compared between implants with or without glenoid lateralization and with or without humeral-sided lateralization. Anteroposterior shoulder radiographs were used to evaluate the LSA and DSA. Results Both angles showed substantial to almost perfect intrarater and inter-rater agreement. Higher LSA values were found in more lateralized RSAs (P = .027), and values between 75° and 95° were correlated with better active external rotation (quadratic regression analysis R2 = 0.553, P Conclusions The LSA and the DSA are reproducible measurements that may be used to estimate “lateralization and distalization” after RSA. These measurements are correlated with postoperative clinical outcomes. |
