Traitement percutané mini-invasif des luxations acromio-claviculaires par vis canulée sous contrôle échographique versus amplificateur de brillance. Une étude prospective

Abstract Introduction To compare percutaneous minimally invasive repair (PMIR) of acute acromioclavicular (AC) joint dislocation under ultrasound guidance (PMIR-UN) vs. C-arm navigation (PMIR-CN). Hypothesis PMIR-UN has similar functional and radiographic outcomes as PMIR-CN. Materials and methods We treated 48 patients with acute grade III or V AC joint dislocation with surgical reduction and fixation with Kirschner wires and cannulated screws. The patients were randomly divided into a PMIR-UN group ( n  = 24) and a PMIR-CN group ( n  = 24). We assessed functional outcomes, operative duration, incision length and intraoperative radiation exposure. Shoulder joint function was evaluated with the Constant–Murley score and postoperative efficacy was evaluated using the Karlsson criteria. Results The median follow-up duration was 13 months (range, 8–18 months). Satisfactory functional outcomes were obtained in both groups. Incision length, incidence of postoperative infection, pin migration and postoperative efficacy did not differ between the two groups. Operative duration and intraoperative radiation dose were significantly greater in the PMIR-CN group than in the PMIR-UN group ( p Discussion Based on the satisfactory results obtained in all patients, we conclude that PMIR-UN is a safe, easy and reliable technique for the treatment of acute grade III or V AC joint dislocation. Type of study Low-powered prospective randomized trial. Level of evidence Level II.
