HYPOTHESIS Dislocation is the most common serious complication after reverse shoulder arthroplasty. One theorized cause is subscapularis insufficiency because the tendon cannot be repaired at the time of surgery. There are no documented risk assessments of reverse total shoulder arthroplasty dislocation related to this cause. The study objective was to quantify the risk of postoperative disloca...

BACKGROUND Fracture sequelae of the proximal part of the humerus are challenging conditions, and various treatment options have been described. The purpose of this multicenter study was to analyze the clinical and radiographic outcomes as well as the complications following semiconstrained reverse total shoulder arthroplasty for the treatment of nonunion of a surgical neck fracture of the proxi...

The authors describe a step-by-step technique for reverse total shoulder arthroplasty using arthrotomy via the enlarged transacromial superior approach. This technique seems ideal for reinsertion of the tuberosities and to ensure adequate postoperative tensional balance of the infraspinatus and the subscapularis, which is critical for the rotator cuffs to function properly and to achieve optima...

Background: The projected increase in revision shoulder arthroplasty has increased interest in the outcomes of theseprocedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoidloosening after anatomic total shoulder arthroplasty (aTSA).Methods: We identified patients who had undergone revision shoulder arthroplasty over a 15-...

Over the last decade, reverse total shoulder arthroplasty has gained significant popularity due to its ability to address difficult reconstructive shoulder problems that could not be adequately treated in the past. The concept of the reverse shoulder prosthesis was introduced in the 1970s, but the initial attempts were associated with high complication and implant failure rates. The pioneering ...

BACKGROUND Proximal humeral fractures are common in older patients. The majority are minimally displaced and are associated with good outcomes after nonoperative treatment. Poorer outcomes are associated with displaced, multipart fractures. There is no clear benefit from surgical fracture fixation compared to nonoperative treatment. Replacement of the fractured humeral head with a hemiarthropla...

Background: The purposes of this study were to determine the average time from hemiarthroplasty (HA) or total shoulder arthroplasty (TSA) conversion reverse (RTSA) and factors leading RTSA.

Background: The purpose of this study was to determine a correlation between surgical case order and the length ofoperative time, total length of time in the operating room, time until discharge from the hospital, and the incidence ofintraoperative complications for primary total shoulder arthroplasty cases.Methods: A retrospective review was conducted of records for all individual primary tota...

BACKGROUND Prior research about symptomatic venous thromboembolism (VTE) after shoulder arthroplasty has not determined whether procedure type (hemiarthroplasty, total shoulder arthroplasty, or reverse shoulder arthroplasty) or surgical indication (traumatic or elective) represent risk factors for VTE after shoulder replacement. QUESTIONS/PURPOSES We therefore asked whether the risk of sympto...
