Abstract:
Nine scaphoid non-unions, which were treated by through curettage of the scar tissue on pseudarthrosis, iliac bone grafts between the fragments and Herbert screws fixation, were analysed. The average follow up period from operation was 16.9 months. The interval between the fracture and the time of the operation ranged from 10 months to 48 months(average 21.6 months). Average union time was 14 weeks after operation. The initial radiologic cystic changes disappeared and overall clinical results were improved. Mean postoperative range of motion of the wrist was flexion 55 and extension 45°. Three of them had DISI deformity preoperatively which their scapholunate angles (mean 104°) has been corrected after reduction (mean 75°). In one case among three DISI deformities, partial radial styloidectomy and triscaphe fusion were added (to bone graft and Herbert screw fixation). A case of incorrect positioning of the screw and a case of neuroma were complicated. Treatment of scaphoid nonunion with curettage of the scar tissue and iliac bone graft and Herbert screw fixation seems to be encouraging to regain the normal anatomy of scaphoid and function of the wrist.
