'''''Long Digital Extensor Tendon'''''
*'''Origin''': Long digital extensor muscle proximal and dorsolateral to the tarsus (hock)
*'''Insertion''': Extensor process of distal phalanx
*'''Action''': Extends the digit, flexes the tarsus
The long digital extensor tendon extends distally on the dorsolateral aspect of the tarsus and metatarsus, surrounded by a synovial sheath from mid-tarsus to 3-4cm distal to the tarsus. The branches of the interosseous muscle (suspensory ligament) join this tendon before its insertion on the '''extensor process''' of the distal phalanx. The long digital extensor tendon is joined by the lateral digital extensor tendon in the proximal metatarsal region.

'''''Lateral Digital Extensor Tendon'''''
*'''Origin''': Lateral digital extensor muscle proximal and lateral to the tarsus (hock)
*'''Insertion''': Dorsal proximal phalanx
*'''Action''': Aids long digital extensor in digit extension and tarsal flexion
The lateral digital extensor tendon passes over the lateral aspect of the 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.
