Tarsocrural luxation

icanis

Synonym(s): Talocrus luxation, Tibiotarsal luxation


Introduction

  • Cause: disruption of collateral support due to closed malleolar fracture, open malleolar fracture/shearing injury, collateral ligament rupture, collateral ligament avulsion.
  • Signs: lateral injuries result in varus (medial) angulation of the foot and medial injuries result in valgus (lateral) deviation. Instability is easily palpable and confirmed radiographically.
  • Diagnosis: radiography, stress radiography, palpation.
  • Treatment: surgical stabilization.
  • Prognosis: management and prognosis will depend upon co-existing injuries and intended function of dog. Reasonable return to function for domestic pet - poor for athletic dog.

Pathogenesis

Etiology

Trauma

  • Significant trauma required to result in talocrural luxation, eg fall or road traffic accident.
