TEACHING OBJECTIVES: To review the current concepts of shoulder arthroplasty. To review the normal post-operative appearance of shoulder arthroplasty including materials, design, and function. To review the imaging appearance of common complications. CONTENTS: Prosthesis material, design, and terminology Preoperative imaging assessment Normal post-operative imaging appearance Imaging findings o...

HYPOTHESIS The aim of this study was to assess the effect of open resection arthroplasty for osteoarthritis of the sternoclavicular (SC) joint on pain levels, functional outcomes, and return to sport. METHODS Patients from a single surgeon's practice who underwent open resection arthroplasty (maximum 10-mm resection) for SC osteoarthritis or prearthritic changes between November 2006 and Nove...

INTRODUCTION Recent evidence suggests a lack of standardization of shoulder arthroplasty outcomes. This issue is a limiting factor in systematic reviews. Core outcome set (COS) methodology could address this problem by delineating a minimum set of outcomes for measurement in all shoulder arthroplasty trials. METHODS A ClinicalTrials.gov search yielded 114 results. Eligible trials were coded o...

Twenty-six consecutive cases of infected primary total knee arthroplasties were treated at our institution from 1989 through 2000. Eleven patients had debridement and irrigation performed within 2 months of index arthroplasty or hematogenous spread; only one infection was eradicated. Twenty-five patients had their prostheses removed; 17 had two-stage revision arthroplasty, following which infec...

QUESTION Do people who have had revision arthroplasty report more limitations and less physical activity than those after primary total hip arthroplasty? Can degree of limitation and physical activity be predicted by revision arthroplasty, after adjustment for age, gender, and Charnley classification? DESIGN Cross-sectional observational study. PARTICIPANTS 371 people after primary and 134 ...

The association between shoulder instability and the development of glenohumeral osteoarthritis has not been well studied in the literature. It is clear that some degree of chondral damage is associated with instability, and there appears to be an increased risk of developing symptomatic osteoarthritis and ultimately requiring a shoulder arthroplasty in patients with a history of instability. M...

PURPOSE To review and compare the postoperative outcomes of 3 types of shoulder reconstructions: prosthetic arthroplasty, clavicula pro humero reconstruction, and allograft arthrodesis. METHODS Records of 25 shoulder reconstructions following tumour resection were retrospectively reviewed. Perioperative data, oncological prognoses, postoperative complications, and functions were assessed. R...

BACKGROUND The complications of reversed total shoulder arthroplasty (RTSA) requiring an additional intervention, their treatment options and outcome are poorly known. It was therefore the purpose of this retrospective study, to identify the reasons for revision of RTSA and to report outcomes. METHODS Four hundred and forty-one performed RTSA implanted between 1999 and 2008 were screened. Six...

BACKGROUND Complex acute proximal humeral fractures may require prosthetic replacement of the proximal humerus. Reverse shoulder arthroplasty (RSA) has been suggested as an alternative to hemiarthroplasty in the management of such fractures. This study compared the functional outcomes of RSA with hemiarthroplasty in patients with acute proximal humeral fractures. MATERIALS AND METHODS All pat...

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...
