Surgical Treatment of Acromioclavicular Dislocation Grade III or IV with thigh Rope System, a retrospective study on the Clinic of Traumatology-Skopje in the period of 2015 to 2018

Abstract

Introduction: Acromioclavicular (AC) dislocation is a common injury with incidence of 3 to 4 per 100 000 in the general population. It is more common in younger athletic patients. In 1984, Rockwood modified Tossy et al and Allman classification to include types IV, V, and VI and we use that classification. The aim of our study is to evaluate surgical treatment of AC dislocation grade III or IV with Tight Rope system and functional results. Materials and Methods: On the Clinic of Traumatology, Skopje in the period of 2015 to 2018 year were treated 32 patients with type III (14 patients) or IV AC dislocation (18 patients) with female to male ratio 0.45 (f:m=10:22). Inclusion criteria were applied to all patients. Three radiographic views were used: AP view, true axillary view and stress view of both sides of the AC joint and CC ligament. Surgical technique for thight rope technique was performed. Results: Dash (Disabilities of the Arm, Shoulder and Hand) and VAS (Visual Analogue Scale) scores were evaluated preoperatively and postoperatively. The DASH questionnaire was used as an indicator of the impact of an impairment on the level and type of disability. Conclusions: The technique proved to be effective in treating acute AC dislocations (Rockwood type III or IV) with a high degree of excellent and good functional results.
