Abstract Background Anatomical reconstruction of the coracoclavicular ligaments is a relatively new technique for acromioclavicular (AC) joint injuries. Methods Eighteen procedures (nine non‐navigated, nine navigated) of anatomical reconstruction were performed minimally invasively, using the Tight Rope system, on cadaveric shoulders. Two Kirschner wires were placed, freehand under fluoroscopic control (non‐navigated) or 3D C‐arm navigated. The insertion point on the clavicle as well as the position of the K‐wire in the coracoid were measured in the axial and coronal planes; points were assigned for different zones. For statistical analysis, the significance level was set to p = 0.05. Results The accuracy of the entry point in the clavicle was significantly more accurate for the conoidal ( p = 0.022) and trapezoidal ( p = 0.0062) drillings. The positioning in the coronal ( p = 0.037) and axial ( p = 0.0416) planes also showed higher accuracy for the navigated procedures. Conclusion The accuracy of anatomical AC joint reconstruction can be improved using 3D C‐arm flat detector navigation. Copyright © 2013 John Wiley & Sons, Ltd.
