Abstract
- PURPOSE
To evaluate the operative methods which can induce an early uinon and better functional outcome in the non-union of scaphoid fracture.
MATERIALS AND METHODS
We evaluated 16 patients (16 cases) who had taken autogenous iliac bone graft and internal fixation with compression screws or K-wires for the treatment of scaphoid fracture non-union. The average follow-up period was 21.1 months. Anteroposterior, lateral and scaphoid views were taken at last follow-up for the purpose of evaluating radiological results. The ranges of wrist motion and grip strength were measured to evaluate functional results, and the patient's subjective responses were also evaluated.
RESULTS
Radiological unions were obtained in 15 cases (93.8%) with the average time to union at 3.2 months (2~7 months) . Radio-ulnar deviation arcs and grip strength were better in the cases fixated with compression screws than K-wires. Twelve patients (75%) showed satisfactory subjective results at the time of last follow up.
CONCLUSION
The iliac bone graft is a good treatment method for scaphoid fracture non-union. We think that the compression screw, which has better stability, is a more profitable fixation device for improved functional recovery.
