Three-dimensional 3-Tesla MR Neurography of the healed sacrotuberous ligament following complete division and grafting.

<p>A: Sagittal oblique multiplanar intermediate-weighted MR image demonstrates continuity of the healed sacrotuberous ligament (STL) (white arrow) after previous complete division, indicative of spontaneous healing. The gray arrow indicates the healed division site. B: Sagittal oblique multiplanar intermediate-weighted MR images demonstrate continuity of a STL allograft (white arrow). C: Two-dimensional 3-Tesla MR Neurography of the healed STL following complete division and grafting, at level of Alcock’s canal. Axial intermediate-weighted MR image demonstrates the anteroposterior dimensions of the healed STL (white arrow) after previous complete division. D: Axial intermediate-weighted MR image the anteroposterior dimensions of the STL allograft (white arrow).
