It is a frequently used procedure in stage II of a posttraumatic degenerative arthrosis of the wrist after scaphoid nonunion or scapholunate ligament instability (SNAC-/SLAC-wrist). In this retrospective analysis the functional postoperative results of this operation are compared in light of a homogenous indication (SNAC-/SLAC-wrist stage II). The job of the wrist (carpus) is to position the hand for function and to transfer load from the hand to the arm. There are 8 bones in the wrist and they sit between the forearm and the hand. Each of these bones has joints around it and so in fact the wrist joint is a complicated joint made up of many joints.
Conservative treatments for scapholunate instability include immobilizing the injured segment and, obviously, refraining from athletic endeavors during the healing period. There are a variety of conservative measures in the mild or early cases that are effective without surgical intervention, including therapeutic modalities.
