The objective of this study was to construct a detailed 3D model of the muscle fibers of the supraspinatus to improve rotator cuff repair. To do so we have acquired n=2 embalmed cadaveric shoulders free of pathology. The shoulders have been imaged via MRI using T2‐Turbo Spin Echo (TSE) protocols with voxel sizes of 0.6x0.5x0.9 mm and 0.4x0.3x3.0 mm. The shoulders have been dissected exposing the supraspinatus. With the use of Microscribe 3D Digitizer we captured the intricate detail of the muscle fibers layer by layer throughout the mass of the supraspinatus. Using the image reconstruction program, Analyze, we spatially registered the MRI and Microscribe data to provide a contextually accurate, 3D depiction of the muscle fibers. More accurate depiction of the fibers is beneficial for understanding muscle fiber alignment during rotator cuff repair as well as postoperative healing.
