BACKGROUND Repetitive tensile stresses from valgus torque can induce elbow injury in adolescent baseball players. Insufficient hip range of motion (ROM) can change throwing mechanics, reducing the transfer of energy from the lower to the upper extremities. Thus, hip ROM limitations may force the upper extremities to bear the burden of a strong throw. Improper pitching mechanics caused by insuff...

We evaluated the morphological changes to the ulnar nerve of both elbows in the cubital tunnel by sonography in a total of 237 children, of whom 117 were aged between six and seven years, 66 between eight and nine years, and 54 between ten and 11 years. We first scanned longitudinally in the extended elbow and then transversely at the medial epicondyle with the elbow extended to 0 degrees . We ...

OBJECTIVE To determine our therapeutic posture trough a comparison of functional treatment results versus immobilization in two different periods. INTRODUCTION For years, the treatment of recent elbow dislocations consisted of reduction and immobilization during 21 days. Given the frequency of stiffness other methods have been tried out. METHOD A prospective study was carried out from Janua...

BACKGROUND The aim of this research was to develop a rat model for vascularized composite allotransplantation (VCA) of the elbow. METHODS We developed an animal model for VCA of the elbow in rats. Microvascular VCA was performed in 9 rats across a major histocompatibility barrier. Three different immunosuppressive regimens were provided. Joint mobility and weight-bearing capability were asses...

Ulnar collateral ligament insufficiency has been shown to result in changes in contact pressure and contact area in the posteromedial elbow. This study used new digital technology to assess the effect of a complete ulnar collateral ligament tear on ulnohumeral contact area, contact pressure, and valgus laxity throughout the throwing motion. Nine elbow cadaveric specimens were tested at 90° and ...

BACKGROUND The effect of elbow medial ulnar collateral ligament injury on posteromedial compartment contact is unknown. HYPOTHESIS Medial ulnar collateral ligament injury causes altered contact area and pressure in the posteromedial compartment of the elbow. STUDY DESIGN Controlled laboratory study. METHODS Seven elbow cadaveric specimens were tested in an apparatus that positioned the el...

OBJECTIVE Our aim was to determine the ideal position of upper extremities during ultrasonography guidance for axillary block. The position that provides the shortest distance between the median and musculocutaneous nerves was assumed to be the most appropriate position for axillary block. METHODS In this cross-sectional study, 120 (45 female and 75 male) patients were placed in a position wi...

Skeletal muscle is the largest tissue structure in our body and plays an essential role for producing motion through integrated action with bones, tendons, ligaments and joints, for stabilizing body position, for generation of heat through cell respiration and for blood glucose disposal. A key function of skeletal muscle is force generation. Non-invasive and selective measurement of muscle cont...

Canine elbow dysplasia is a complex of diseases that includes ununited anconeal process, fragmented medial coronoid process, osteochondrosis of the medial humeral condyle, and elbow incongruity. Three causes of elbow dysplasia have been proposed: osteochondrosis, trochlear notch dysplasia, and asynchronous growth of the radius and ulna. Genetics, nutritional imbalance, growth disturbances, and ...
