Operative treatment outcomes of anterior sternoclavicular joint dislocation using two experimental methods - an acromioclavicular joint hook plate versus a locking plate: a retrospective study

Abstract

Background We aimed to compare the intraoperative and early postoperative clinical outcomes of using an acromioclavicular joint hook plate (AJHP) versus a locking plate (LP) in the treatment of anterior sternoclavicular joint dislocation. Methods Seventeen patients with anterior sternoclavicular joint dislocation were retrospectively analyzed from May 2014 to September 2019. Six patients were surgically treated with an AJHP, and 11 were surgically treated with an LP. Five male and one female patients composed the AJHP group, and nine male and two female patients composed the LP group. The mean age of all patients was 49.5 years. Results Reduction and fixation were performed with AJHP or LP in all 17 patients. The mean operative blood loss, operative time, and length of incision in the AJHP group were significantly better than those in the LP group. Shoulder girdle movement of the AJHP group was significantly better than that of the LP group. Conclusions This study revealed that AJHP facilitated glenohumeral joint motion, reduced the risk of rupture of mediastinal structures, required a shorter incision, and had lesser blood loss and a shorter duration of operation compared with LP. However, some deficiencies require further improvement.

“… 11 Surgical techniques include medial clavicle resection, open reduction and internal fixation with plates and screws, or ligamentous repair and reconstruction using various soft-tissue grafts. 12 , 13 , 14 , 15 , 16 Techniques using orthopaedic hardware are associated with complications like implant loosening and the need for a secondary hardware procedure. 17 , 18 Ligamentous reconstruction using a figure-of-8 configuration demonstrates robust biomechanical strength without the aforementioned concerns.…”
