Optimizing humeral stem fixation in revision reverse shoulder arthroplasty with the cement-within-cement technique.

Background: The purpose of this study was to report on the clinical outcomes of patients undergoing revision reverse shoulder arthroplasty (RSA) by the cement-within-cement technique, as well as to identify whether surgical technique can affect subsequent humeral loosening.

Methods: In 98 patients, cemented humeral components that were revised to RSA using the cement-within-cement technique were identified and included in this study. We compared 8 patients in whom humeral stem loosening developed with 90 patients whose stem remained fixed.

Defining the younger patient: age as a predictive factor for outcomes in shoulder arthroplasty.

Background: The purpose of this study was to define an age cutoff at which clinical outcomes and revision rates differ for patients undergoing primary anatomic total shoulder arthroplasty (TSA) and patients undergoing primary reverse shoulder arthroplasty (RSA).

Methods: This retrospective cohort study included 1250 primary shoulder arthroplasties (1131 patients) with minimum 2-year clinical follow-up (mean, 50 months [range, 24-146 months]). TSA (n = 518; mean age, 68.

Use of a modified Outerbridge-Kashiwagi procedure for the treatment of posttraumatic elbow sequelae.

Background: To review our 10-year experience treating posttraumatic sequelae of the elbow using a modified Outerbridge-Kashiwagi (O-K) procedure.

Methods: Twenty-one patients with posttraumatic sequelae of the elbow treated using the technique were evaluated clinically using the Mayo Elbow Performance Score, range of motion testing, and pain level. We noted the presence of preoperative and postoperative ulnar nerve symptoms, complications, and reoperations.
