Purpose of the study: We retrospectively reviewed the experience of two Hand Units with progressive bone distraction lengthening, collecting 41 cases of hand skeleton lengthening for congenital malformations. Material and methods: The Ilizarov callostasis method was used in 31 cases and in 10 cases bone union was reestablished at a second stage with an iliac graft (2 cases), vascularized metacarpal bone graft (one case), and vascularized (one case) or nonvascularized (3 cases) toe epiphysis. In the last three cases of index lengthening, the distal part was translocated to the tip of the third, deepening at the same stage the first web. The most frequently treated malformation was symbrachydactyly (22 cases). Results: Mean lengthening was 2.3 cm (0.9 to 3.5) with a mean treatment duration of 3.8 months (1.5 - 8.2). The "lengthening index" was 0.59. There was a significant difference between phalanx and metacarpal lengthening, but the amount of lengthening or treatment duration were not affected by technique (llizarov vs bone grafting) or age. The complication rate was 32 %. There were two complete failures, one extensor tendon tear, 3 pin tract infections (one requiring interruption of the lengthening), 2 cases of relevant pain, 2 delayed unions, 2 angulations and 1 callus fracture, 1 metacarpophalangeal dislocation and 1 joint stiffness. Discussion: Despite advances in micorsurgical toe transfer, there are still indications for bone lengthening in congenital malformations. The apparent simplicity of the technique can mask a certain number of complications, emphasizing the need for surgical experience. Progressive bone lengthening in congenital deformity has the advantage of preserving sensitivity and avoiding bone resorption. Callostasis does not increase the duration of treatment compared to bone graft.
