BACKGROUND The Oxford Shoulder Score (OSS) is a reliable and valid construct measuring non-specific shoulder pain, which are widely used to evaluate shoulder related quality of life. This study was to cross-culturally adapt and psychometrically validate a simplified Chinese version of the OSS (SC-OSS). METHODS Cross-cultural adaptation was performed according to the international recognized g...

OBJECTIVES To translate and adapt the Western Ontario Shoulder Instability (WOSI) questionnaire into Danish and, to evaluate measurement properties of an electronic Danish WOSI version. METHODS The Swedish WOSI version was used for translation and adaptation into Danish followed by examination of test-retest reproducibility (14-day interval) besides concurrent and construct validity.

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...

BACKGROUND Reverse total shoulder arthroplasty (RTSA) has been indicated primarily for patients aged older than 65 years with symptomatic rotator cuff deficiency, poor function, and pain. However, conditions that benefit from RTSA are not restricted to an elderly population. This study evaluates a consecutive series of RTSA patients aged younger than 60 years. METHODS We evaluated 36 shoulder...

Objectives: This paper evaluates the usefulness of a set of PROMs data collected prospectively, in a relational database, over several years. The data were collected as part of routine practice, to audit patients undergoing shoulder surgery. Methods: Data, rendered anonymous, which included all upper limb surgical procedures and all outcome questionnaires (including Oxford Shoulder Score, OSS) ...

Nowadays, the exact efficacy of intramedullary devices fixation and plate fixation for adult displaced midshaft clavicle fractures (DMCF) is still debated. This study aims to re-assess the functional outcomes and complications of the two optimal surgical approaches. Cochrane Central Register of Controlled Trials, EMABASE, and PubMed databases were searched for the literature that studied the ef...

The Hill-Sachs lesion is an osseous defect of the humeral head that is typically associated with anterior shoulder instability. The incidence of these lesions in the setting of glenohumeral instability is relatively high and approaches 100% in persons with recurrent anterior shoulder instability. Reverse Hill-Sachs lesion has been described in patients with posterior shoulder instability. Gleno...

Aim. To evaluate results of Aequalis humeral head resurfacing in patients with end-stage glenohumeral arthritis at a minimum followup of two years. Patients and Methods. Twenty-one consecutive patients underwent humeral head resurfacing hemiarthroplasty between 2007 and 2009. Three patients did not fulfill the inclusion criteria. 18 patients with mean age of 75.1 years (range 58-91 years) and a...
