Abstract:
Objective:To evaluate the early clinical and radiographic outcome of scaphoid non unions treated with Acu-trak headless compression screw. Methods:From January 2008 to July 2011,21 patients with scaphoid non union were treated in our department. There were 18 males and 3 females with a mean age of (23.6±4.6) years;12 cases were on right hand and 9 were on left. According to Herbert-Fisher classification,there were 10 cases with type D1,7 cases with type D2,3 cases with type D3,and 1 case with type D4. The mean time from injury to operation was (12.4±2.7) months. All patients were treated with Acutrak headless compression screw fixation (6 cases received 2 screws fixation,15 cases received 1 screw fixation,and Matti-Russe bone grafting was applied in 7 cases). The carpal height,the scaphoid index and changes of the scapholunate an-gle were assessed before and after the operation. Range of motion and grip strength were recorded and the wrist function was assessed according to the Patient-Rated Wrist Evaluation (PRWE). Results:Average duration of follow up was (21.3±3.6) months. All the patients attained radiological union in a mean time of (13.3±2.4) weeks following the operation. No obvious complications were recorded. The surgical treatment allowed the preoperative mean scaphoid index of 0.61±0.13 and the pre-operative mean scapholunate angle of (59.4±6.8)° to be improved to 0.69±0.10 and(44.3±8.2)° postoperatively,respectively. There was a substantial improvement in grip strength and pain amelioration after surgery. The preoperative mean PRWE score of 45.2 ±4.7 was improved to 76.1 ±5.2 postoperatively. All patients returned back to the original work ,the average time from surgery to work was (6.0±1.1) months. Conclusion:For scaphoid non unions,Acutrak headless compression screw fixation can provide anatomical reduction,provide satisfactory results with a high union rate,well return of function and minimal complica-tions in the early stage.
