The use of total shoulder arthroplasty (TSA) to treat primary glenohumeral osteoarthritis (GHOA) is increasing. Factors influencing patient satisfaction after surgery have not been well documented. The aim of this study was to determine demographic, radiologic, and surgical, factors predictive for satisfaction after TSA for GHOA. Between 2005 and 2012, 95(More)
BACKGROUND Lateral clavicle fractures have been reported after coracoclavicular (CC) ligament reconstructions with bone tunnels through the clavicle. PURPOSE To biomechanically compare clavicle strength following 2 common CC reconstruction techniques with different bone tunnel diameters. STUDY DESIGN Controlled laboratory study. METHODS Testing was(More)
The surgical fixation of unstable, varus displaced two-part fractures of the proximal humerus remains challenging. In a case series of 10 non-compliant, high-risk patients (median age 63 years; range 52–78), a cancellous allograft was used to augment plate fixation of the fractures. After a median follow-up of 28.5 months, all but one fracture were healed,(More)
Antegrade nailing of proximal humeral fractures using a straight nail can damage the bony insertion of the supraspinatus tendon and may lead to varus failure of the construct. In order to establish the ideal anatomical landmarks for insertion of the nail and their clinical relevance we analysed CT scans of bilateral proximal humeri in 200 patients (mean age(More)
The purpose of this study was to evaluate the clinical results of surgical repair for proximal long head of the biceps (LHB) tendon ruptures comparing chronic primary and postsurgical revision LHB tendon ruptures. Patients who underwent subpectoral LHB tenodesis for chronic ruptures with a minimum of 2 years from surgery were identified. ASES and SF-12 PCS(More)
The aim of the treatment of displaced scaphoid non-unions is the restoration of normal scaphoid anatomy. Restoration of normal scaphoid anatomy at an earlier stage might have functional benefits as maladaptive carpal ligament contractures and the development of preliminary osteoarthritis could be avoided. The purpose of this retrospective study was to(More)
BACKGROUND Straight antegrade intramedullary nailing of proximal humerus fractures has shown promising clinical results. However, up to 36% of all humeri seem to be "critical types" in terms of the potential violation of the supraspinatus (SSP) tendon footprint by the nail's insertion zone. The aims of this study were to evaluate if a computed tomography(More)
Varus failure is one of the most common failure modes following surgical treatment of proximal humeral fractures. Straight antegrade nails (SAN) theoretically provide increased stability by anchoring to the densest zone of the proximal humerus (subchondral zone) with the end of the nail. The aim of this study was to biomechanically investigate the(More)
The purpose of this study was to determine the biomechanical effects of placing the biceps tenodesis stitch at the musculotendinous junction versus in the tendon only. Placing the stitch at the musculotendinous junction was hypothesized to result in a significantly weaker repair than stitching in the tendon only. Testing was performed on two groups of six(More)
BACKGROUND Humeral fracture after subpectoral tenodesis of the long head of biceps tendon (LHB) is a rare but devastating complication. PURPOSE To determine whether malpositioned (laterally eccentric) tenodesis screw placement has an influence on humerus strength reduction compared with central placement. STUDY DESIGN Controlled laboratory study. (More)
