Abstract Purpose The surgical treatment of acute traumatic AC joint dislocations is still a subject scientific debate in the literature. arthroscopically assisted stabilization procedure with suture button system has been successfully established and widely used daily practice. It minimally invasive allows anatomical reconstruction torn coracoclavicular ligaments one step permanent implant that does not have to be removed second operation. This clinical pilot study first describe new method navigated implantation future aim further reducing invasiveness increasing precision. Materials methods 10 patients Rockwood 3b/5 injury could included prospective (DRKS00031855) within 5 months according inclusion exclusion criteria. Surgical was performed via drill tunnel. Demographic radiological data as well information on health shoulder function were collected from patient records, X-rays, DVT scan 3 questionnaires (DASH, NHS Eq. 5D) at preoperative, intraoperative postoperative (discharge, 6 weeks months) time points. Results All operations 8.8 days (± 6.81) after trauma. average operation 50.3 min 8.81). mean distance hole clavicle 26.6 mm 2.63). radiologically measured vertical 38.8 6.16) discharge 41.11 7.51) months. loss reduction statistically significant. In contrast, DASH, 5D results showed significant improvement postoperatively. Conclusion Image-guided 3D C-arm feasible everyday may possible achieve while same accuracy positioning. Further studies larger number longer follow-up period are necessary enable comparison conventional methods.
