Surgical treatment of acute Rockwood III acromioclavicular dislocations—Comparative study between two flip-button techniques

Abstract

Acromioclavicular joint dislocation is a common shoulder injury, usually caused by direct violence on the shoulder. optimal treatment of type iii is still a hot discussion currently in orthopedic surgeons. With the advent of many flip-button techniques, Tightrope system and Endobutton system become popular techniques for reconstruction of coracoclavicular ligaments. the purpose of the study was to compare the clinical and radiological results between the two techniques. A retrospective casecontrol study was conducted in 60 patients with acute Rockwood III acromioclavicular joint dislocation. the two techniques conducted were open procedures using twin tail tightrope system (Group A, n = 30) and Endobutton system (Group B, n = 30). 60 patients were followed up at least two years. Surgical parameters including incision length, operation time and operative blood loss were analyzed. Functional outcomes were evaluated using the Constant-Murley Score. Radiological results were assessed based on coracoclavicular distance preoperatively, one day postoperatively, and at the final follow-up. 60 patients were followed up for at least 24 months (range 24 to 32). The incision length and operation time were shorter in Group A than that in Group B. The blood loss of surgery was significantly less in the Group A. There were no significant differences between the two groups regarding the Constant-Murley Score at the final follow-up. No significant differences were found in the coracoclavicular distance preoperatively, immediately postoperatively, and at the final follow-up. Both techniques offered satisfying functional outcomes, however the Tightrope system provided better surgical parameters.

Surgical Management of Acute Rockwood Grade III Acromioclavicular Joint Dislocations: A Systematic Review

“…After screening titles/abstracts for satisfying inclusion/exclusion criteria, 177 abstracts were further excluded, leaving 34 unique studies for full-text review. Finally, 14 studies that reported outcomes after the surgical management of acute Rockwood grade III acromioclavicular dislocations were included in this systematic review (Figure 1) [12,19,[26][27][28][29][30][31][32][33][34][35][36][37].…”

A Self‐Designed Endobutton Installation Device for Coracoclavicular Stabilization in Acute Rockwood Type III Acromioclavicular Joint Dislocation

“…However, each of these surgical techniques has complications and the best treatment strategy for CC stabilization remains controversial. The most commonly used surgical procedure is internal fixation with the Endobutton technique, 23 , 24 which can be performed either via open surgery, mini‐open surgery, or arthroscopically. 15 , 16 , 21 Endobuttons technique provide flexible CC stabilization for ACJ dislocation.…”
