Some Devices in the Hand Surgery

Abstract

A little device sometimes brings good results in hand surgery. Some of our new devices are presented.
1. Old unreduced dislocations of distal radioulnar joint. Bunnell and Liebolt stabilized the joint by free tendon, however good results were not obtained.
Using sublimis tendon as a dynamic stabilizer, we obtained a good result.
2. Nonunions of the scaphoid.
Bone graft by Russe's method is commonly accepted. However in two cases because of small proximal fragment or radiocarpal osteoarthritis, we performed transposition of free tendon in defect of resected proximal scaphold and obtained good results.
3. End to end suture of tendons.
Tendon suture techniques were developed recently on the basis of intratendinous circulation.
However in practice, incongruity or rotational malposition was often observed at anastomosis.
So, we apply stay-sutures of 7/0 nylon bilaterally, then performed Tsuge's tendon suture.
This simple device needs no additional stitches and makes the suture much easier.
