| Abstract |
|
From 1994 to 1997, we performed 14 metatarsals lengthening and 3 met acarpals lengthening in 13 adolescent patient s by met aphyseal ost eotomy followed gradual distraction of callus (callotasis) using an external fixators. Congenit al and acquired shortness of met acarpal and metatarsal may cause not only cosmetic problem but also pain adjacent met atar sals. Excellent clinical result s were obtained. The average lengthening and percent original lengthening were 12.9mm (range from 6.4mm to 20.0mm) and 33.9% (range from 15% to 50%). The average lengthening days were 60.6 days. No one required bone grafting after the lengthening and there was no severe complication (stops the lengthening and course of treatment ). We used a rigid, unilateral external fixator designed for use in the hand and foot and one Ilizarov external fixator (60mm half ring x 2). At the time of last follow- up, from 12 months and 4 year s later, healing had been achieved in all with an average healing index 85 days/ cm, an average healing time 112 days and the corrections of the length of the met atar sals and metacarpals were done. We concluded that the ost eotomy with gradual distraction without bone grafting was one of the effect methods for the treatment of lengthening of short tubular bone. |
