Aim:
To investigate the anatomical relationships of the structures and the topographic anatomy of the sacrospinous ligament and validate current anatomic knowledge of this area.
Materials:
Nine embalmed half female cadaver pelvises were dissected to reveal the anatomy of the sacrospinous ligament.
Results:
The average length of the sacrospinous ligament was measured to be 43.04 +/- 6.58 mm. The inferior gluteal complex emerges from the infrapiriform foramen at a distance of 17.02 +/- 3.08 mm from the ischial spine and courses to inferior-laterally with a slight curve. During this course, it passes close to the upper-lateral half of the sacrospinous ligament. The pudendal complex passes above the spine in six of the nine cases (66.6%) and lies maximum of 5.5 mm medial to the spine. On average the sciatic nerve is measured to be 25.14 +/- 3.94 mm lateral to the ischial spine.
Conclusion:
Placing the suture inferomedially and close to sacrum, the risk of complication will be minimal.
