[Surgical treatment of congenital brachymetacarpus by dynamic elongation osteosynthesis. Report of a clinical case].

Dynamic elongation osteosynthesis is a new technique studied and applied by us in the treatment of congenital brachymetacarpal deformity. The anatomical, functional and aesthetic results of this operation in a young woman were excellent. We used a microtractor according to Ilizarov's in order to achieve methodology 22 mm of lengthening of the fourth metacarpal bone of the left hand. All soft tissue structures were elongated such as arteries, veins, nerves, intrinsic muscles, flexor and extensor tendons without any adverse effects. We therefore recommend this technique for the treatment of this congenital disease.
