Indiscriminate ossification of ligaments in a dry adult human male pelvis– A rarity

Abstract Full Text PDF


Introduction: Human pelvis exhibits sacrotuberous, sacrospinous and transverse acetabular ligament performing the function of stabilisation of pelvis and hip joint respectively. The ossification of this ligaments has been reported solitary and rarely in composite.
Materials and Methods: During undergraduate osteology teaching authors noticed a dry human male pelvis demonstrating compounded ossification of ligaments and bony distortions.
Case Report: The left sacrotuberous ligament was partially ossified and demonstrated triangular anteroinferior and posterosuperior segments. The transverse acetabular ligament of right side was totally ossified and left was partially ossified. A bony mass was observed at the left ala of sacrum with fusion of pedicle and left lower part of body of fifth lumbar vertebra and ala of sacrum. Bilateral sharp bony spicules at iliopectineal lines and exostosis at bilateral iliac tuberosity was noticed. 
Conclusion: This exhibit brings out an unreported rare anatomical variant of bony pelvis, the knowledge of which will be of paramount importance to radiologists and orthopaedic surgeons.

Keywords: Sacrotuberous ligament, Transverse acetabular ligament, Ossification, Sacralisation, Bony spicule.
