[Glide amplitude of flexor and extensor tendons of the fingers of the human hand].

The gliding amplitude of the flexor and extensor tendons of the finger muscles were determined in the human hands of adults. The carpometacarpal transition area and also the middle zone of the proximal and middle phalanx were appointed as measuring marks. In the main the amplitudes on the flexor side are constantly greater than on the extensor side. Because the movements decrease from proximal to distal, also the gliding range during tendon excursion lessens in the proximo-distal direction. In the case of replantation the extensor tendons should be shortened by the same amount as the bone. To relieve tension in the suture, the flexor tendons should be kept at their original length.
