The tarsus, commonly known as the hock, is a complex joint located in the hind limb of horses. It consists of several bones, including the tibia, talus, calcaneus, and several smaller tarsal bones, which together form a hinge-like structure. The tarsus plays a significant role in locomotion by providing stability, support, and flexibility to the hind limb during movement. It is a frequent site of injury and various orthopedic conditions, such as osteoarthritis, bone spavin, and synovitis, which can impact a horse's performance and well-being. This page compiles peer-reviewed research studies and scholarly articles that explore the anatomy, biomechanics, common pathologies, and treatment options associated with the equine tarsus.
Myers TJ, Sampson SN, Glass KP, Russell LA.Central tarsal bone (CTB) fractures are challenging to diagnose, and cross-sectional imaging is required for definitive characterization and surgical planning. This retrospective case series aims to provide the first description of high-field (3-T) MRI characteristics of CTB fractures, concurrent pathology, and clinical presentation in 8 performance horses. Unassigned: 8 horses (9 limbs) diagnosed with a CTB fracture on high-field MRI at one tertiary referral hospital between 2013 and 2023 were identified via electronic medical records search. Unassigned: Quarter Horses (6 of 8) used for Weste...
Ursini T, Villagomez A, Dooley M, George LS, Levine D.To describe and demonstrate subjective and objective techniques for assessing the quality and passive range of motion (ROM) of the distal forelimb and hind limb joints of the horse. Special attention will be given to the tarsus, carpus, and fetlock joints, as these sites are most prone to injury and/or pathology and thus most clinically relevant. Unassigned: Adult horses undergoing distal limb joint ROM assessment for clinical diagnostic or treatment monitoring purposes. Unassigned: First, subjective techniques for assessing distal limb joint motion and end-feel as well as general guidelines f...
