The lateral digital extensor tendon passes over the lateral aspect of the [[Joints and Ligaments - Horse Anatomy#Pelvic Limb|hock]] , held in place by the '''extensor retinaculum''' and surrounded by a protective synovial sheath. It joins the '''long digital extensor tendon''' in the proximal metatarsal region.

In the horse, the medial insertion of the cranial tibial muscle (tibialis cranialis) is known as the '''cunean tendon'''. There is an associated synovial fluid-filled space known as the '''cunean bursa''', which is also species specific.
