The aim of the study was to examine the correlation between the chosen position of screws and the complications observed in patients who underwent locked plating of proximal humeral fractures. We evaluated radiographs of 367 patients treated by locked-plating for proximal humeral fractures. Radiographs were taken at one day, 6 weeks, 3 months and 6 months after surgery, and were analyzed for se...

BACKGROUND Spontaneous fracture of the humeral shaft in throwers is a rare but well-known phenomenon. Although it has been hypothesized that the biomechanics of the throw cause such fractures, it is not clear how or when the fractures occur in the pitching motion. METHODS The torque acting about the long axis of the humerus was calculated in 25 professional baseball pitchers throwing in game ...

Core decompression may used in the management of early stage, precollapse nontraumatic osteonecrosis of the humeral head. We propose a technique without risk of complications associated with injury to the biceps tendon or the blood supply to the humeral head.

Restoration of joint stability during total shoulder arthroplasty can be challenging in the face of severe glenoid retroversion. A novel technique of humeral head component anterior-offsetting has been proposed to address posterior instability. We evaluated the biomechanical benefits of this technique in cadaveric specimens. Total shoulder arthroplasty was performed in 14 cadaveric shoulders fr...

AIMS To compare nationwide time trends and mortality in hip and proximal humeral fractures; to explore associations between incidences of falls risk related comorbidities (FRICs) and incidence of fractures. METHODS The study is a retrospective cohort study using nationwide Danish administrative registries from 2000 through 2009. Individuals aged 65 years or older who experienced a hip or a pr...

BACKGROUND No clear recommendations exist regarding optimal humeral component version and deltoid tension in reverse total shoulder arthroplasty (TSA). MATERIALS AND METHODS A biomechanical shoulder simulator tested humeral versions (0°, 10°, 20° retroversion) and implant thicknesses (-3, 0, +3 mm from baseline) after reverse TSA in human cadavers. Abduction and external rotation ranges of mo...

BACKGROUND Deformity and growth arrest of the humerus in children may result as sequelae of proximal humerus fractures and unicameral bone cysts, or as complications of their treatment. As approximately 80% of the growth of the humerus arises from the proximal physis, the resultant upper limb-length discrepancy can be substantial. Benefits to lengthening the shortened arm have been previously d...

Glenoid and humeral head bone loss is the most common cause of failure after surgical shoulder instability stabilization. Large Hill-Sachs lesions involving >30% of the articular surface of the humeral head typically occur after neglected or locked shoulder dislocations. Such large lesions may require osteochondral allograft reconstruction or prosthetic replacement to regain shoulder stability ...

PURPOSE Displaced medial humeral epicondyle fractures with or without elbow dislocation have been treated with open reduction and fixation using K-wires or screws. The purpose of this study is to evaluate the clinical and radiological outcomes of surgical treatments of medial humeral epicondyle fracture without elbow dislocation according to the fixation methods. MATERIALS AND METHODS Thirty-...
