Presurgical Planning for L Dorsi Position Optimization: Combined Simulation and Cadaver Study

A study to determine the optimal insertion point of the latissimus dorsi muscle for treatment of rotator cuff tears using in-silico biomechanical models. A cadaver trial was used to validate the simulation results. The optimal area for insertion for improving glenohumeral rotation throughout a range of flexion was found to be the center of the greater tuberosity.
