To evaluate the functional result of scaphoid nonunion treated with the use of a Herbert screw and bone grafting
Arif Kamal

Aim: The aim of this study to evaluate the functional outcome of scaphoid nonunion treated with bone grafting and Herbert screw fixation. Methods: This study was done the Department of Orthopedics. 80 cases were referralsfrom peripheral centers with a possible diagnosis of scaphoid nonunion after failed conservative treatment. 80patients were initially assessed with fresh radiographs and MRI wrist was taken in all cases. The injuries were classified according to Herbert’s Classification. Clinical examination included the assessment of tenderness, active and passive range of movement in wrist, and grip strengths were also measured. A firm padded removable splints were used to support the wrist for the first two weeks and after the suture removal, patients are advised to start mobilizing exercises of the wrist. Results: There were 80 cases of scaphoid nonunion treated with Herbert screw fixation and cancellous bone grafting. The mean age of the patients was 30.35 years. Our study resulted in 60% excellent, 26.25% good and 13.75% fair functional outcomes. 3 patient each in good and fair groups had mild pain post operatively. 96.25% of patients were satisfied with the outcome of the procedure mostly because they could return to job with a painless joint. Wrist function was assessed by range of movement and grip strength which was greatly improved after Herbert screw fixation of the scaphoid. The movement which was mostly difficult improve was wrist dorsiflexion after reconstruction. The rigid internal fixation of the scaphoid resulted in significant decrease in pain. Most of our patients had moderate to severe pain preoperatively, but 85% cases had no pain at the latest review. Conclusions: We concluded that the healing of the nonunion is better than that in other surgeries like k wire fixation or bone graft surgeries alone.
