Abstract EN
Supraspinatus tendon tears are common and lead to changes in the muscle architecture.
To date, these changes have not been investigated for the distinct regions and parts of the pathologic supraspinatus.
The purpose of this study was to create a novel three-dimensional (3D) model of the muscle architecture throughout the supraspinatus and to compare the architecture between muscle regions and parts in relation to tear severity.
Twelve cadaveric specimens with varying degrees of tendon tears were used.
Three-dimensional coordinates of fiber bundles were collected in situ using serial dissection and digitization.
Data were reconstructed and modeled in 3D using Maya.
Fiber bundle length (FBL) and pennation angle (PA) were computed and analyzed.
FBL was significantly shorter in specimens with large retracted tears compared to smaller tears, with the deeper fibers being significantly shorter than other parts in the anterior region.
PA was significantly greater in specimens with large retracted tears, with the superficial fibers often demonstrating the largest PA.
The posterior region was absent in two specimens with extensive tears.
Architectural changes associated with tendon tears affect the regions and varying depths of supraspinatus differently.
The results provide important insights on residual function of the pathologic muscle, and the 3D model includes detailed data that can be used in future modeling studies.
