[Humerus lengthening in a unilateral technique: case report].

Surgical lengthening of the humerus is indicated for cosmetic and functional reasons. The discrepancy should exceed 4 cm. Complications (review of literature) and our own experience regarding lengthening of extremities indicate that surgical lengthening of the humerus is technically feasible and reasonably safe. It appears to have fewer risks and complications than surgical lengthening of the femur or the tibia; even though radial nerve paralysis is an important complication.
