The purpose of this study was to compare prospecti- vely the radiographic and clinical results of patients treated with tightrope through either mini-open or percutaneous stabilization for acute AC joint injuries.

Eighty patients were included in this study and were randomly divided into two groups. Group A included 40 injuries treated with mini-open repair. Group B consisted of 40 injuries treated with percutaneous stabilization. Demographic and clinical data were comparable between the two groups before surgery (P>0.05). Peri-operative data, complications and clinical outcomes between the two groups were compared. The average follow-up time of Group A, was 26.5±4.3 months and Group B, was 25.2±5.6 months (P>0.05). The mean operative time was 63.2±9.6 minutes and 45.6±7.1 minutes, and the mean incision length was 6.0±1.5 cm and 4.0±0.8 cm, respectively. The operative time and incision length were significantly longer in Group A (both P<0.05). However, the radiological assessment revealed no significant difference in the coracoclavicular (CC) distance between the two groups (P>0.05). The rate of loss of reduction in the Group A was similar to that in Group B (6/40 vs. 5/40, P>0.05).

Both methods were efficient methods for acute AC joint dislocation. However, percutaneous fixation had the advantages of a shorter surgical time and smaller incision length.
