ABSTRACT
Objective To compare the effects of application of clavicular hook plate combined with wire anchors anatomical coracoclavicular ligament reconstruction and application of clavicular hook plate in the treatment of NeerII distal clavicle fracture and Tossy Ⅲtype~V acromioclavicular joint dislocation. Methods A retrospective analysis of the clinical data from June 2006 to June 2013. Total 73 cases patients suffered with Neer Ⅱtype distal clavicle fractures and Tossy Ⅲtype~V acromioclavicular joint dislocation. Of which , 41 cases were subjected to treatment with clavicular hook plate , 32 patients subjected to treatment of using clavicular hook plate combined with anchors .The incision length, operative time, postoperative complications, length of hospital stay and postoperative 1 month, 6 month shoulder VAS score of two groups were analyzed; the shoulder function of both groups after 1 month, 6 months were assessed by using Constant shoulder function assessment method. Results Surgical incision length and operational time between the two groups were statistically significant (P<0.05), while the amount of bleeding was not statistically significant. All patients were followed up . The two groups did not occur any complications such as loosening, decoupling, acromioclavicular joint dislocation and wound infections. Hospitalization time was 5~14 d (averaged 10d), no significant difference between two groups. 4 the shoulder Constant score and VAS scores showed no significant difference 1 months postoperation; 6 months after hook plate removed, VAS score and Constant shoulder score improved significantly in anchors hook plate group (P<0.05). Conclusion Anatomical coracoclavicular ligament reconstruction by application of hook plate combined with anchors is a good biomechanical model characterized with simple surgery , less trauma and good clinical outcomes , worthy of clinical application.
