Functions of the Tarsal (Hock) Orthosis

The tarsal orthosis is designed to provide targeted stabilization of the canine hock joint and to limit excessive or unwanted movement that may compromise joint integrity or delay recovery. By supporting controlled motion, the orthosis assists functional limb use while helping to manage acute injury or chronic instability.

As with our other orthotic devices, the tarsal brace is manufactured from lightweight yet durable thermoplastic materials. This ensures effective support while minimizing additional load on the limb and maintaining comfort during daily activity and rehabilitation.

Tarsal injuries may result from acute traumatic events or from repetitive stress that places excessive strain on the supporting structures of the joint, including the common calcaneal (Achilles) tendon. In these cases, appropriate joint stabilization is essential to prevent further tissue overload.

Our tarsal orthoses are designed to support the distal tibia and limit excessive plantarflexion or hyperextension of the hock joint, thereby reducing abnormal loading of the Achilles tendon. When clinically indicated, the orthosis can be equipped with an adjustable strap system that allows controlled range of motion, supporting functional movement while restricting harmful joint excursion.

By limiting excessive motion and supporting proper alignment, a tarsal orthosis can help reduce the risk of re-injury and contribute to improved joint stabilization and tissue recovery as part of a comprehensive treatment or rehabilitation plan.

In selected cases, tarsal orthoses may also be suitable for feline patients. Suitability for use in cats must be assessed individually, taking into account the animal's health status, anatomy, and specific clinical needs. Professional consultation is required prior to application.

Who Is a Tarsal (Hock) Orthosis Intended For?

A tarsal orthosis may be considered for dogs requiring stabilization and controlled support of the hock joint in a variety of clinical situations, including:

• Support following Achilles tendon injury
  Orthotic stabilization of the tarsal joint may be used during recovery from injury to the common calcaneal (Achilles) tendon to support controlled movement and reduce excessive strain on healing structures.

• Post-operative support after tarsal arthrodesis
  Following surgical procedures such as arthrodesis, a tarsal orthosis may assist in stabilizing the joint and supporting controlled limb use during the recovery period.

• Support after medial or lateral collateral ligament injury
  In cases of collateral ligament damage, orthotic support may help improve joint stability and protect healing soft tissues.

• Support following digital flexor tendon injuries
  A tarsal brace can assist in managing flexor tendon injuries by providing joint support and controlled range of motion.

• Management of tarsal hyperextension or instability
  Orthotic stabilization may help limit excessive hyperextension and reduce abnormal joint motion associated with instability.

• Assistance with neurological deficits affecting paw placement
  In dogs with neurological conditions resulting in abnormal paw positioning or involuntary digital flexion or extension, a tarsal orthosis may be adjusted to help support controlled limb placement during stance and gait.

• Support in cases of failed or incomplete arthrodesis
  When surgical stabilization does not achieve the expected outcome, a tarsal orthosis may help provide additional joint support and reduce discomfort, allowing continued functional movement.

Each case is individually assessed to determine whether a tarsal orthotic solution is clinically appropriate and aligned with the dog's condition, functional needs, and overall treatment plan.
