Abstract

Purpose
: We reviewed seven patients with symptomatic degenerative osteoarthritis secondary to scaphoid nonunion and represent surgical procedure of distal scaphoid resection arthroplasty to document the clinical results of treatment. Materials and Methods : Seven patients who underwent distal scaphoid resection arthroplasty had been followed for average of twelve months(range, six to twenty months). All were men and the average age was thirty-eight years(range, thirty two to fifty years). Results : Range of motion of wrist joint improved in the flexion extension arc from 84.3 degrees(range, 30 to 120) before surgery to average of 108.6 degrees(range, 75 to 130 degrees) after surgery. Two had complete pain relief and were able to perform vigorous activity. Five had mild pain, but did not require any medication. Little change has been noted after surgery and carpal height changed only 11% and radiolunate angle increased 12 degrees. Conclusion : Distal scaphoid resection arthroplasty for chronic symptomatic degenerative arthritis due to scaphoid nonunion can reduce external immobilization time, enable patients to return to work earlier and save time until arthrodesis.
