In horses the short branch of the '''dorsal sacroiliac ligaments''' connects the sacral tuberosity to the spinous processes of the sacrum. The '''sacrotuberous ligament''' is a broad sheet-like ligament, which extends between the transverse processes of the first caudal vertebrae and the dorsal border of ischium and ilium. In this ligament are the '''lesser and greater ischiatic foramen''', these are present to allow for blood vessels, nerves and tendons.

The horse has a limited range of hip movement compared to the dog. This is mainly restricted to flexion and extension and is a result of the conformation of its femoral head, intra-articular ligaments and a large muscle mass around the joint. The '''ligament of the femoral head''' extends from the acetabulum to the fovea on the femoral head. Unlike other species, the horse also has an extra ligament present in the joint; the '''accessory ligament'''. The accessory ligament arises from the tendon of insertion of  the ''rectus abdominis'' muscle and to a lesser extent ''external abdominal oblique'' muscle as part of the ''prepubic tendon'' and inserts on the fovea. Both ligaments pass through '''acetabular notch'''.
