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...

Professor Grammont revolutionised shoulder surgery with his reverse shoulder arthroplasty design. Patients who had poor results from a conventional shoulder replacement because of cuff deficiency can now be treated effectively. Although designed for cuff tear arthropathy, indications continue to evolve and broaden. The initial results look very promising and the implant has gained much populari...

BACKGROUND The Nordic Arthroplasty Register Association was initiated in 2007, and several papers about hip and knee arthroplasty have been published. Inspired by this, we aimed to examine the feasibility of merging data from the Nordic national shoulder arthroplasty registries by defining a common minimal data set. METHODS A group of surgeons met in 2014 to discuss the feasibility of merging...

BACKGROUND Very little data exist regarding patients' preoperative expectations of the outcome of total shoulder arthroplasty. We hypothesized that younger patients and patients with worse function and worse general health would have greater expectations of total shoulder arthroplasty. METHODS Ninety-eight patients who underwent unilateral primary total shoulder arthroplasty at one institutio...

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...

Glenoid morphology has an important impact on outcomes and complication rates after shoulder arthroplasty for primary glenohumeral arthritis. The B2 glenoid, or a biconcave glenoid with posterior humeral head subluxation, in particular has been associated with a poorer outcome with shoulder arthroplasty compared with other glenoid types. A variety of techniques may be used to address the bone d...

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...

BACKGROUND Cuff tear arthropathy is the primary indication for total reverse shoulder arthroplasty. In patients with pseudoparalytic shoulders secondary to irreparable rotator cuff tear, reverse shoulder arthroplasty allows restoration of active anterior elevation and painless shoulder. High rates of glenoid notching have also been reported. We designed a new reverse shoulder arthroplasty with ...

BACKGROUND AND PURPOSE Different results after shoulder arthroplasty have been found for different diagnostic groups. We evaluated function, pain, and quality of life after shoulder arthroplasty in 4 diagnostic groups. PATIENTS AND METHODS Patients with shoulder arthroplasties registered in the Norwegian Arthroplasty Register from 1994 through 2008 were posted a questionnaire in 2010. 1,107 p...
