Arthritis Clinical Trials

Two surgical procedures are used to treat a post-traumatic wrist osteoarthritis, especially after scaphoid non-union advanced collapse (SNAC) and scapholunate advanced collapse (SLAC): the proximal row carpectomy and the four corner fusion. Both surgical procedures are rescue operations. They are used to reduce pain and to maintain the mobility, compared to a complete stiffening of the wrist.

In previous studies are shown that the proximal row carpectomy shows a better mobility of the wrist postoperatively and a lower complication rate, whereas the four corner fusion has a lower progression of radiocarpale osteoarthritis and a better grip strength.

The purpose of this study is to compare the clinical, radiological and subjective outcomes after the treatment with a proximal row carpectomy or a four corner fusion.
