Sacrotuberous Ligament Healing following Surgical Division during Transgluteal Pudendal Nerve Decompression: A 3-Tesla MR Neurography Study
Fig 5
Post-operative pudendal nerve three-dimensional 3-Tesla MR Neurography of the sacrotuberous ligament 3 months (A) and 8 months (B) following sacrotuberous ligament division.
A: Sagittal oblique multiplanar T2-weighted MR images with fat suppression demonstrate the continuous left sacrotuberous ligament (STL) (asterisks) with healing division site (white arrow). The gray arrow demonstrates the pudendal nerve subjacent to the STL. B: Sagittal oblique multiplanar T2-weighted MR images with fat suppression demonstrate the continuous right sacrotuberous ligament (STL) (asterisks) with healing division site (white arrow). The gray arrow demonstrates the pudendal nerve subjacent to the STL. C: Sagittal oblique multiplanar intermediate-weighted MR images demonstrate the continuous left STL (asterisks) with healed division site (white arrow). The gray arrow demonstrates the pudendal nerve subjacent to the STL. D: Sagittal oblique multiplanar intermediate-weighted MR images demonstrate the continuous left STL (asterisks) with healed division site (white arrow). The gray arrow demonstrates the pudendal nerve subjacent to the STL.
