Although mixing and matching components is a common, safe, and well-documented practice in hip revision surgery, our extensive search indicates that it has not been previously reported for shoulder arthroplasty. This case report presents the use of mixed implants in shoulder revision surgery to reduce morbidity and address flaws in the initial implant design. We describe a case of a patient with multiple epiphyseal dysplasia who was treated for osteoarthritis in his left shoulder with an anatomic shoulder replacement in 2014.

Background And Objectives: The management of complex upper limb arthroplasty has received national guidelines supporting the use of a regional network. An upper limb network was established for both elbow and shoulder arthroplasty. This study evaluates the impact of establishing this network over a 5-year period.

- The study examined the impact of glenoid vault perforation during shoulder arthroplasty, questioning the assumption that it leads to worse outcomes.
- Out of 83 patients, only 8% had perforation, with no significant differences in clinical or radiological outcomes compared to those without perforation.
- Remarkably, most implants (92%) did not perforate the vault, and the perforated cases still resulted in excellent outcomes without any need for revision surgery.
Abstract: We previously reported the mean 4-year outcomes of anatomic total shoulder replacement using an all-polyethylene, pegged, hybrid-fixation (bone ingrowth and cement) glenoid component. In the present study, we report on that patient cohort after another 4 years of follow-up (mean, 101 months; range, 77 to 146 months). At that time, the median American Shoulder and Elbow Surgeons (ASES) score was 92 points (interquartile range [IQR], 81.

The purpose of this study was to evaluate the early clinical and radiographic results following use of an all-polyethylene pegged glenoid component designed for hybrid (biological and cement) fixation.
Methods: Eighty-three shoulders in 77 patients (mean age, 68.
