[Lengthening of residual digit by gradual traction and bone grafting (a report of 143 cases)].

Since 1985, a device for gradual traction was used for lengthening of 143 residual digits in 75 patients. The average lengthening was 2.2 cm. This method is simple, safe, and effective. The advantages of this method over the previously exercised tubed bone graft and other digital lengthening methods are that the digit reconstructed by the gradual traction-lengthening method has the normal cutaneous structure, good sensation function, and better contour. Multiple digits can be reconstructed simultaneously. Because the periosteum at the osteotomy site is kept intact, the long term results are consistent.
