RESUMO
The authors analyzed 14 patients with severe osteomyelitis of the upper extremity between 1985 and 1992, managed with the vascularized fibular graft. Eleven radii, two humeri and one ulna were reconstructed. Bone loss after resection ranged from 6 to 12 cm (mean 8.14 cm). Follow-up ranged from 8 months to 7 years and 10 months (mean 3 years and 3 months). The therapeutic applications of the vascularized fibular graft in severe bone infections of the upper extremity were discussed and the good results of this surgical procedure established it as a good option for treatment. Morbidity at the donor site was minimal.

The authors reviewed 62 neurotizations of the brachial plexus in 71 patients performed between 1974 and 1989. The nerves used were the accessory, the motor or sensory branches of the cervical plexus, and the intercostals. Twenty-five suprascapular nerves, 19 musculocutaneous, 4 medial roots of the median nerve, and 12 lateral roots of the median nerve were neurotized. The authors concluded that useful results can be achieved using extraplexual neurotizations.

A dichotic listening paradigm was used to study the relation of eye movement to cerebral lateralization. The eye movements of right-handed subjects were recorded during verbal and nonverbal dichotic-listening tasks. Subjects given a verbal dichotic-listening task made significantly more rightward than leftward eye movements and showed more accuracy and speed in processing information presented to the right than to the left ear. Subjects given a nonverbal dichotic-listening task made significantly more leftward eye movements and processed better information presented to the left ear. These findings suggest a potentially strong link between the direction of lateral eye movement during dichotic listening tasks and left- and right-ear advantages in performance on such tasks. They also suggest that both eye movement and ear performance may be related to cerebral laterality and when examined in combination both could provide valuable information for the further study of hemispheric specialization.
