Abstract Background Aseptic loosening of glenoid implants is the primary revision cause in anatomic total shoulder arthroplasty (aTSA). While supported by biomechanical studies, impact bone quality, more specifically mineral density (BMD), on aseptic remains unclear. We hypothesized that lower preoperative BMD was associated with implant aTSA. Methods retrospectively included 93 patients (69 fe...

Fractures around the acromion are a known complication of reverse total shoulder arthroplasty. The literature provides limited data on the risk factors associated with this complication as well as the ultimate outcomes after nonoperative treatment. The goal of this study was to report clinical outcomes in patients with acromial fractures after nonoperatively treated reverse total shoulder arthr...

Rheumatoid arthritis (RA) of the shoulder affects both bony and soft-tissue structures around the glenohumeral joint and destroys the rotator cuff, and leads to loss of function, instability, and chronic incongruency of the joint. Lehtinen et al. [1] 2000 reported a natural history of 148 RA shoulders with a 15-year follow-up. The result was upward migration, medialization, and flattening of th...

Failure of shoulder arthroplasty is often defined as a complication or the need for revision, but it may also be viewed as a result that does not meet the expectations of the patient. To enhance our understanding of failed shoulder arthroplasties, we identified the characteristics common to a series of 139 consecutive patients who came to our shoulder consultation service because of dissatisfac...
