The aim of the study was to evaluate whether arthroscopic (ASC) repair of rotator cuff ruptures causes less postoperative pain and better range of motion (ROM) in the early postoperative period than a mini-open (MO) technique. Inclusion criteria were a rupture of the supraspinatus tendon with retraction with a maximum to the apex of the humeral head and(More)
Our aim in this prospective study was to evaluate the outcome of total shoulder replacement in the treatment of young and middle-aged active patients with primary glenohumeral osteoarthritis. We reviewed 21 patients (21 shoulders) with a mean age of 55 years (37 to 60). The mean follow-up was seven years (5 to 9). The same anatomical, third-generation,(More)
The aim of this retrospective study was to analyse the clinical, functional and radiographic outcomes of patients sustaining traumatic anterior dislocations of the shoulder in combination with large anterior glenoid rim fractures, treated by open reduction and internal screw fixation (ORIF). Twenty-nine patients with a mean follow-up of 6.5 years (2.5–12(More)
BACKGROUND The Latarjet procedure is effective in managing anterior glenohumeral instability in the short term, but there is concern for postoperative arthritis. The purpose of this study was to evaluate the long-term functional outcome after the Latarjet procedure and to assess the prevalence of and risk factors for glenohumeral arthritis after this(More)
AIM Three-dimensional motion analysis of the lower limb has been an approved method of diagnosis and therapy planning for several years. In this study we observed the range of motion of the shoulder and elbow in 10 activities of daily life (ADL) with a marker-based biomechanical model for the upper extremity. With this database we hope to improve the(More)
BACKGROUND AND OBJECTIVES The aim of this study was to analyze our results using a modular endoprosthetic replacement system (MUTARS) for bone tumors of the proximal humerus. METHODS Thirty-nine patients were treated with a MUTARS endoprosthesis of the proximal humerus. Mean follow-up duration was 38 months (3-138 months). Most operations were(More)
BACKGROUND Studies evaluating the return to sports and work after shoulder arthroplasty are rare, and there are no studies evaluating return to work after total shoulder arthroplasty (TSA). HYPOTHESIS Patients undergoing TSA will be able to return to their preoperative sports levels and occupations. STUDY DESIGN Case series; Level of evidence, 4. (More)
Scapular notching is a common worrying finding after reverse total shoulder arthroplasty (RSA). Eccentric glenospheres have recently been developed in an attempt to prevent notching. The purpose of this study was to evaluate the clinical and radiological results of RSA with an eccentric glenosphere and compare the incidence and the severity of scapular(More)
BACKGROUND There is little information about the long-term longitudinal outcomes of total shoulder arthroplasty. Moreover, long-term data on a single shoulder replacement system are lacking. The aim of this study was to analyze, at different time points during a follow-up period of fifteen to twenty years, the clinical and radiographic outcomes of patients(More)
The aim of this study was to analyse the complication rates of six different shoulder arthroplasty concepts for different diagnoses in the short and midterm. The study included 485 primary shoulder arthroplasties. The mean follow-up of the cohort was 3.5 (1–10) years. Complications were classified into three categories: (1) without reoperation, (2) soft(More)
