Skin problems in the treatment of the finger "en crochet".

The study of 33 fixed flexion contractures of the finger shows that after tenolysis or teno-arthrolysis a skin gap appears when the finger is extended. Only 10 cases out of 33 had previous cutaneous involvement. The necessary skin plasties have been 14 heterodigital flaps and 19 local dorsal-lateral flaps. Results are comparable in both series and the surface of the skin defect has no influence on the choice of the type of flap. Therefore, whenever possible, a local flap is preferred to a distal flap.
