Background and purpose - The number of patients where shoulder hemiarthroplasty (SHA) is an option is still substantial. Descriptive analyses performed by the Swedish Shoulder Arthroplasty Registry (SSAR) showed that while patients receiving SHA designs, i.e. resurfacing hemi (RH) and stemmed hemi (SH), reported similar shoulder functionality and quality of life, the revision rate for RH (12%) ...

Background: Given high rates of positive Cutibacterium acnes (C. acnes) cultures in cases of both primary and revisionshoulder surgery, the ramifications of positive C. acnes cultures remain uncertain. Next generation sequencing (NGS)is a molecular tool that sequences the whole bacterial genome and is capable of identifying pathogens and the relativepercent abundance in which ...

synovial chondromatosis affecting the glenohumeral joint is rare. treatment primarily consists of arthroscopic loose body removal and synovectomy. shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. the case of an 84-year-old man with long standing synovial chondromatosis of the sh...

The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty.The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%.The most common complications of RSA include instability, infection, notching,...

The authors report the 2-year results of an uncemented resurfacing shoulder prosthesis in 47 patients with primary glenohumeral osteoarthritis who underwent a cementless humeral resurfacing arthroplasty between 2007 and 2009. Constant scores (corrected for sex and age), shoulder function, visual analog pain scales, Dutch Simple Shoulder Tests, and physical SF-12 scores improved significantly (P...

Prosthetic shoulder arthroplasty is becoming increasingly popular. The most widely reported procedures are hemiarthroplasty and unconstrained total arthroplasty using the Neer II prosthesis, which involves insertion of a press-fit or cemented humeral component and a cemented polyethylene glenoid implant. Long-term studies show that excellent or good results are achieved in over 90% of cases, wi...

BACKGROUND Treatment of complex three and four-part proximal humeral fractures with hemiarthroplasty in elderly patients has yielded mixed clinical results. Reverse shoulder arthroplasty has emerged as a treatment option for comminuted proximal humeral fractures for these patients. The purpose of the study was to perform a prospective evaluation of patient outcomes comparing hemiarthroplasty an...

BACKGROUND Irreparable rotator cuff (RC) tears without arthritis is a challenging clinical problem in young adults. Reverse total shoulder arthroplasty (RTSA) has been proposed as one of the surgical treatment options for this condition. METHODS In this review, we discuss the current understanding of the role of RTSA for the management of irreparable RC tears without arthritis based on author...
