In order to determine the effects of two different headless screw designs on fixation of simulated capitellum fractures six matched pairs of embalmed humeri had simulated capitellum fractures created. Fixation with Acutrac compression screws was compared to Herbert screws in a matched pair experimental design. All specimens were cyclically tested with… (More)
The anatomy of the ulnar nerve is described from its origin at the brachial plexus to its termination in the hand and digits. The critical anatomy surrounding the cubital tunnel and Guyon canal is emphasized, and clinically relevant anatomic variations, muscle anomalies, and peripheral nerve anastomoses are described.
PURPOSE To evaluate dexterity and grip strength after simulated distal interphalangeal (DIP) joint fusion of the index and middle fingers in varying degrees of flexion. METHODS Forty-six right-handed subjects performed grip and dexterity testing using the Grooved Pegboard Test in positions of index finger 20° flexion or full extension, middle finger 20°… (More)
We present the unusual case of a flexor carpi radialis tendon that ruptured after extended strenuous physical activity by a patient with paralysis of the opposite limb secondary to poliomyelitis.
