Abstract

The present study describes the morphometry of a unilateral ossified sacrotuberous ligament. It aims to discuss its Anatomical and clinical implications.The pudendal nerve, internal pudendal artery, nerve to obturator internus and coccygeal branch of inferior gluteal artery, are the important structures related to sacrotuberous ligament. An ossified sacrotuberous ligament may be an important etiological factor in neurovascular compression syndromes and its anatomical knowledge may help in the development of new treatment strategy for this common clinical problem. The ossified sacrotuberous ligament in the present case exhibits, a characteristic anterior and posterior segment, a base at the ischial tuberosity and an apex attached to alae of sacrum. The ossified sacrotuberous ligament may be important in differential diagnosis of soft tissue pain and tenderness after trauma. It may be a challenging puzzle for the present day surgeon and radiologist in interpretation of radiological problems.
