The acetabular labrum is a triangular fibrocartilaginous structure that forms a horseshoe-shaped attachment to the acetabular rim, which connects the acetabulum to the underlying transverse acetabular ligament
8 The vascular compromise of femoral head may also be caused due to excessive abduction and internal rotation during the maintenance of reduction in Spica cast or injury to circumflex artery while cutting the transverse acetabular ligament
The ligament, which is pyramidal in shape, may consist of multiple bundles, and blends with the transverse acetabular ligament
Otherwise, through the same incision, the inferomedial hip joint capsule was opened, the ligamentum teres was excised, and the transverse acetabular ligament
was sectioned to obtain an anatomic reduction during the same operative session.
3,9) It is triangular in cross-section, thinner antero-inferiorly, thicker and rounded posteriorly and merges with the transverse acetabular ligament
at the inferior border of the acetabular rim.
