Abstract
The aim of this study was to compare the early clinical and functional outcomes of patients who received the 2 major variations of reverse shoulder arthroplasty (RSA). The nonlateralized Aequalis Reversed Shoulder System (Tornier, Nice, France) was followed by the lateralized Encore Reverse Shoulder Prosthesis (DJO Surgical, Austin, Texas). Patient-determined pain and functional scores and examiner-determined range of motion and strength were assessed preoperatively and postoperatively at 1, 6, 12 weeks, and 6 months. Seventy RSAs performed in 66 consecutive patients: 35 shoulders in the lateralized group and 35 shoulders in the nonlateralized group met the inclusion criteria and formed the cohorts. Both groups experienced similar excellent clinical outcomes, with the exception that the lateralized group had better internal rotation range of motion (L3-4 vs. S1, P=0.03), lower frequency of pain during sleep (P=0.04), less severe pain at rest (P=0.03) and higher involvement in sporting activities (P=0.04) at 24 weeks. In conclusion, patients who underwent RSA with a lateralized glenosphere had better internal rotation range of motion, less pain, and better function than those who received a nonlateralized prosthesis. These differences were apparent within 6 months postsurgery. Level of Evidence: Level III.
期刊介绍:
Published quarterly, Techniques in Shoulder & Elbow Surgery escorts the reader into the operating room and supplies step-by-step details of exciting and advanced techniques. It explains the evolution of and rationale for the procedures, identifies the pitfalls and possible complications, provides invaluable tips for improving surgical results and it is illustrated cover to cover with high-quality intraoperative photographs and drawings, many in full color.
