BackgroundAC joint injury is a common disorder with a reported incidence of three to four cases per 100.000. A multitude of surgical techniques has been described for the treatment of the AC joint injuries with no clear consensus regarding the optimal treatment. We hypothesized that we would obtain favorable clinical outcomes using a novel minimally-invasive polymer cerclage wire system compared to other reported techniques in the literature.MethodsAll adult patients treated with subacute AC separations in our department between the dates of 2014-2017 were retrospectively reviewed clinically and radiographically. Clinical outcomes scores that were obtained preoperatively and postoperatively included ASES score, constant score and the UCLA shoulder rating scale.ResultsFive patients with Type 5 AC separations were included in this study who underwent surgical treatment by the same orthopedic surgeon (G.H.) using the same minimally-invasive technique. The mean follow-up period was 22.4 months (range 18 to 29). Mean preoperative coracoclavicular (CC) distance was 19.7 mm (range 16.4 to 24.5 mm) on the surgical side and 9.48 mm on the contralateral side. Mean early postoperative CC distance was 7.1 mm (range 4.5 to 11.2 mm). At the latest follow-up, the mean CC distance was 13.8 mm (range 7.3 to 21.2 mm). Mean preoperative Constant score was 48, the UCLA shoulder rating score was 14.8, and the ASES shoulder score was 49.26. Mean follow up Constant score was 91.6, UCLA shoulder rating score was 33.8 and ASES shoulder score was 93.75. No neurovascular complication was observed after procedure. There were no cases of clinical or radiographic failure or loss of fixation. No AC joint arthritis was observed at the latest follow-up.ConclusionWe present a novel minimally-invasive polymer cerclage wire technique which provides comparable results as other reported arthroscopic and open techniques for Type 5 AC joint separations.
