[Matev's digit lengthening technic. Apropos of 20 cases].

The authors reviewed 20 lengthening procedures according to Matev performed between 1982 and 1985 at SOS Main Strasbourg. They developed a special device which has proved to be simple and easy to use. Indications are limited to a few congenital malformations and traumatic mutilations. In children a free vascularized epiphysis transfer has been used to allow normal growth. Results are analysed and short-comings are outlined: lengthening is limited (47.8%); frequency of complications mainly trivial account for 25%; treatment period is lengthy (2.8 m in children and 4.2 m in adults).
