Prostheses for reverse total shoulder arthroplasty

Expert Review of Medical Devices, 2019
Historically, patients with rotator cuff arthropathy had limited reconstructive options. The early generations of reverse total shoulder arthroplasty (rTSA) designs had increased failure rates due to loosening of glenoid baseplates secondary to excessive torques. In 1985, Paul Grammont introduced a prosthetic design changing the center of rotation that

Revision for instability following reverse total shoulder arthroplasty: outcomes and risk factors for failure.

Journal of shoulder and elbow surgery, 2023
BACKGROUND Revision of unstable reverse shoulder arthroplasty (RSA) is significantly challenging with recurrence rates ranging 20-40%. The purpose of this study was to identify factors associated with recurrent instability. The factors studied included 1)

Biomechanics of reverse total shoulder arthroplasty

Journal of Shoulder and Elbow Surgery, 2015
Reverse total shoulder arthroplasty is an effective procedure for treatment of glenohumeral joint disease among patients with severe rotator cuff deficiency. Improvements in prosthetic design are the result of an evolved understanding of both shoulder and joint replacement biomechanics.

Instability in Reverse Total Shoulder Arthroplasty

Journal of the American Academy of Orthopaedic Surgeons, 2018
Recently, indications for reverse total shoulder arthroplasty have expanded to include glenohumeral arthritis, rotator cuff arthropathy, irreparable rotator cuff tears, complex proximal humerus fractures, sequelae of trauma, and failed shoulder prostheses. Dislocation is a common complication, with rates ranging from 1.5% to 31%.

Outcomes of an anatomic total shoulder arthroplasty with a contralateral reverse total shoulder arthroplasty

Journal of Shoulder and Elbow Surgery, 2018
It is common for patients to require staged bilateral shoulder arthroplasties. There is a unique cohort of patients who require an anatomic total shoulder arthroplasty (TSA) and a contralateral reverse shoulder arthroplasty (RSA). This study compared the outcomes of patients with a TSA in 1 shoulder and an RSA in the contralateral shoulder.Our ...

Scapulothoracic orientation has a significant influence on the clinical outcome after reverse total shoulder arthroplasty.

Journal of shoulder and elbow surgery
BACKGROUND Computer simulation has indicated a significant effect of scapulothoracic orientation and posture on range of motion (ROM) after reverse total shoulder arthroplasty (RTSA).

Patient-specific instrumentation improves the reproducibility of preoperative planning for the positioning of baseplate components with reverse total shoulder arthroplasty: A comparative clinical study in 39 patients.

Journal of shoulder and elbow surgery, 2022
BACKGROUND The application of patient-specific instrumentation (PSI) for reverse total shoulder replacement has been rapidly increasing, which could reduce errors in implant positioning.

Reverse total shoulder arthroplasty

Clinical Anatomy, 2008
AbstractReverse total shoulder arthroplasty designs have gained popularity over the last few years due to their satisfactory functional results in patients with cuff‐tear arthropathy and other difficult reconstructive shoulder problems. These semiconstrained prostheses improve stability and active elevation in the absence of a functional rotator cuff ...
