UNLABELLED Worldwide, the usage of both anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthro- plasty (rTSA) has increased significantly due, in part, to the predictability of acceptable outcomes achieved with each prosthesis type. This study quantifies outcomes using five different metrics and compares results using one platform total shoulder arthroplasty system that u...

Introduction Reverse shoulder arthroplasty is an increasingly popular treatment option for cuff tear arthropathy and other degenerative conditions of the glenohumeral joint that have been previously treated with limited success. Concerns about scapular notching have driven design and surgical technique modifications by manufacturers and surgeons in order to improve range of motion (ROM) and sta...

HYPOTHESIS Revision shoulder arthroplasty represents a complex and difficult problem for the treating surgeon, with multiple potential complications. In the setting of a well-fixed humeral component, removal can lead to fractures and compromise the outcome of the revision. The current study describes and evaluates the results of a novel vertical humeral osteotomy (VHO) for stem extraction. We h...

Background and purpose - The number of shoulder registries increases. We assessed international trends in use of shoulder arthroplasty, and described the current state of procedure selection and outcome presentation as documented in national and regional joint registries. Methods - Published reports from 9 population-based shoulder arthroplasty registries (country/region: Norway, Sweden, New Ze...

In addition to neurologic injuries such as peripheral nerve palsy, axillary vessel injury should be recognized as a possible complication of reverse total shoulder arthroplasty. Limb lengthening associated with Grammont-type reverse total shoulder arthroplasty places tension across the brachial plexus and axillary vessels and may contribute to observed injuries. The Grammont-type reverse total ...

The increase in the number of shoulder arthroplasties has also created a paradoxical increase in the number of revision procedures. These revision surgeries can be complicated by well-fixed humeral components that require removal. In this article, we report a representative revision arthroplasty that involved a novel technique, vertical humeral osteotomy, which allowed for safe and effective hu...

UNLABELLED Reversed total shoulder arthroplasty (RTSA) has well known indications and good to excellent results are described in the literature. When the arthroplasty fails however, revision remains a technical challenge with many questions unanswered. To analyse retrospectively and consecutively the indications and results of primary RTSA-revision. All patients that underwent revision RTSA bet...

The purpose of this retrospective study was to assess the effect of the reduced medialisation of the Arrow reverse shoulder prosthesis on short-term clinical and radiological results. The clinical and radiological results of 47 Delta III reverse prostheses and 49 Arrow reverse prostheses were retrospectively compared at a minimum of twelve months follow-up. There was a significant increase (p <...
