We studied normal hand strength and the difference between dominant and nondominant hands. Two hundred fourteen volunteers were tested with a calibrated Jamar dynamometer at all five levels. A pinch gauge was used to assess key and pulp pinch. Height, weight, sex, hand dominance, and hobby demands were predictive of maximum grip. Mean maximum grip for women(More)
Each of 480 extremities from 120 cadavers was dissected. Particular attention was given to potential donors for tendon grafts. Both the palmaris longus and the extensor digiti minimi had an average length of 16 cm and an average width of 3 mm. The extensor indicis tendon averaged 13 cm in length and 3 mm in width. The plantaris and second toe extensors(More)
The brachial plexus may be visualized simply as beginning with five nerves and terminating in five nerves. It begins with the anterior rami of C5, C6, C7, C8, and the first thoracic nerve. It terminates with the formation of the musculocutaneous, median, ulnar, axillary, and radial nerves. The intermediate portions are displayed in sets of threes: three(More)
Thirty-six digits with an intra-articular fracture of the dorsal aspect of the distal phalanx that involved one-third or more of the articular surface were treated by open reduction and internal fixation with Kirschner wires. After an average length of follow-up of forty-six months, roentgenograms of the distal joint in twenty-six digits appeared(More)
The amplitude of gliding of the flexor tendons was measured in 36 hands tagged intraoperatively with buried wire sutures. Finger and wrist position was correlated with tendon excursion as measured on radiographs in the postoperative period. With the wrist in the neutral position, the superficialis tendon achieved an excursion of 24 mm and the profundus(More)
