Evaluation of five different incisions for correction of radial dysplasia.

The complications of the five different incisions used for centralization from 1970 to 1996 were evaluated. In five cases access was by an S- shaped incision, in one with a transposition flap. Sixteen centralizations were done using a radial Z-plasty in combination with an ulnar excision and four by using two opposite Z- plasties, preserving wrist mobility as much as possible. In 1995 and 1996 a bilobed flap was used in seven cases. No complications occurred with the primary procedures prior to 1995. In all seven cases where the bilobed flap was used venous congestion was seen. In four out of these seven superficial necrosis of parts of the flaps occurred. In all cases though wound healing occurred spontaneously by delayed primary healing after the standard 8 weeks of cast immobilization.
