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 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 degree to which subjective patient-reported measures reflects objective findings or how well subjective and objective measures reflect patient satisfaction is not well established. The purpose of this study was to determine the correlation between such measures before and after shoulder arthroplasty. A group of 174 patients (93 total shoulder arthroplasty and 81 reverse shoulder arthroplast...
Clinicians have had much experience with uncemented humeral components. A press-fitted humeral component will usually remain stable in the absence of a glenoid component. From the information available, surgeons should not continue to use press-fitted humeral components for total shoulder arthroplasty. Tissue ingrowth humeral components offer promise; however, the reports to date have short or ...
Glenoid component failure is the most common complication of total shoulder arthroplasty. Glenoid components fail as a result of their inability to replicate essential properties of the normal glenoid articular surface to achieve durable fixation to the underlying bone, to withstand repeated eccentric loads and glenohumeral translation, and to resist wear and deformation. The possibility of gle...
Inflammatory or degenerative processes in glenohumeral joint lead to pain and restriction of movements of the shoulder. Prosthetic replacement of the glenohumeral joint has gained in popularity because of its efficacy in relieving pain. The pioneering successful prostheses for total shoulder arthroplasty (TSA) have been based on an unconstrained de‐ sign, i.e. a metal spherical head component f...
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...
HYPOTHESIS Glenoid erosion and medial migration of the humeral head prosthesis have been observed after most types of shoulder arthroplasty. A method of measuring the change in humeral head position with time after shoulder prosthetic arthroplasty was applied it to 14 shoulders that underwent humeral hemiarthroplasty with concentric glenoid reaming. We hypothesized that the measurement techniqu...
