PURPOSE: The treatment of scaphoid nonunion with @entity571 poses a clinical problem that is particularly challenging in cases of associated dorsal intercalated segmental instability collapse, radiocarpal and intercarpal degenerative changes, and poor scaphoid bone quality. The purpose of this study was to report our clinical experience performing a distal scaphoid resection for symptomatic scaphoid nonunion in @entity1 with either radioscaphoid or intercarpal @entity625 who have had multiple surgeries. METHODS: Nine @entity1 with recalcitrant scaphoid nonunion and associated @entity571 treated by resection of the distal scaphoid fragment were evaluated both clinically and radiographically. Eight @entity1 were male and one @entity1 was female; the average follow-up period was 28.6 months (range, 12-52 mo). RESULTS: Seven @entity1 reported @entity158 with daily use and the remaining 2 @entity1 reported mild @entity158 with light work before surgery, whereas after surgery 4 of the 9 @entity1 had no wrist @entity158 and the remaining 5 @entity1 had only mild @entity158 with strenuous activity. The wrist range of motion improved from 70 degrees (51.4% of the opposite wrist) to 140 degrees (94% of the opposite wrist) and grip strength improved from 18 kg (40% of the opposite wrist) to 30 kg (77% of the opposite wrist). Clinical results were excellent in 6 @entity1 and good in 3 @entity1 based on a modified Mayo wrist-scoring chart. Radiographically neither additional degeneration nor progress of degenerative changes was noted after surgery in 8 @entity1 . Newly developed @entity571 occurred at the proximal scapholunate capitate articulation in the remaining @entity1 who has a type II lunate, which had a facet (medial facet) articulation with the hamate. CONCLUSIONS: The results of this study showed that distal scaphoid resection produces a satisfactory clinical outcome, requires only a short period of immobilization, and should be considered one of the surgical options for long-standing scaphoid nonunion with either radioscaphoid or @entity571 . Nevertheless care must be taken in performing this procedure on @entity1 whose preoperative radiograph show a type II lunate.
