Surgical treatment of acromioclavicular dislocation with coracoclavicular screw and double Endobutton plate / 中华创伤杂志

ABSTRACT

Objective To evaluate and compare the clinical outcome of coracoclavicular screw and double Endobutton plate in treatment of acromioclavicular dislocation ( Rockwood Ⅲ-Ⅴ ). Methods Twenty-eight patients with Rockwood Ⅲ-Ⅴ acromioclavicular dislocation were subjected to surgical reconstruction from January 2008 to October 2009. The coracoclavicular screw was performed in 14 patients and the double Endobutton plate in the other 14 patients. Clinical evaluation was performed by using Constant score and subject should value (SSV) in both groups, and the preoperative and postoperative radiographs, curative effects and complications were compared. Results The patients in two groups were followed up for a range of 6-25 months (average 12.6 months) , which showed higher postoperative Constant score and SSV score than preoperation in both groups (P＜0.05). But the postoperative Constant sore and postoperative SSV score in the double Endobutton group were (89.8 ±8.3) points and (85.7 ±7. 3) points respectively, significantly better than (78. 0 ± 10. 3) points and (71. 8 ±9. 7) points respectively in the coracoclavicular screw group ( P ＜ 0.05). The radiologic measurement showed no significant difference in regard of the coracoclavicular distance three months after operation in two groups (P＞0.05). Conclusions The double Endobutton plate can attain significantly superior clinical outcomes for Rockwood Ⅲ-Ⅴ acromioclavicular dislocation compared with the coracoclavicular screw. The surgical technique of reconstructing the coracoclavicular ligament through anatomical approach will be the future trend in treatment of the acromioclavicular joint dislocation.
