Abstract

• There is difficuity in the treatment of scaphoid nonunion, because of it is not easy to diagnosis scaphoid fracture after affecting the damage, and also of inadequate treatment.
  We have performed wedge bone Graft and internal fixation in treatment of 52scaphoid nonunions from April, 1986 to June, 1994.
  We got result as below by analysis of 27 cases which could follow up more than one year.
  1. The most frequent age of fracture is the 3rd decade and the fracthre is more frequent in men (26 cases)than in woman (1 case).
  2. The X-ray fingings of nonunion are bony sclerosis (13 cases), cystic change(3 cases), and absorption of fracture line (11 cases).
  3. The mean period of bony union is 14.7 weeks.
  4. In 8 cases there has been dorsal intercalated segmental instability(DISI) on preoperative X-ray finding and which is corrected after operation.
  5. In evaluatory system by Herbert and Fischer about degree of patients satisfaction, the grade 0 is 15 cases, grade 1 is 11 cases and grade 2 is 1 case, in clinical results, grade 0 is 15 cases, grade lis 9 cases and grade 2 is 3 cases, in radiographic result, grade 0 is 22 cases, grade 1 is 4 cases, grado 2 is 1 case.
