Tarsometatarsal luxation

Contributor(s): Sorrel Langley-Hobbs

Introduction

  • Less common injury than talocrural or proximal intertarsal luxation.
  • May occur in combination with proximal intertarsal luxation.
  • Subluxation with plantar instability more disabling than with dorsal or dorsomedial instability.
  • May be concurrent fractures of tarsal bones.
  • Cause: trauma.
  • Signs: acute onset hindlimb lameness.
  • Treatment: coaptation or internal fixation (dorsal instability); tarsometatarsal arthrodesis (severe luxation or plantar ligament compromise).
  • Prognosis: good for return to normal function in pet dog.

Pathogenesis

Etiology

  • Trauma.

Pathophysiology

  • Traumatically-induced luxation of tarsometatarsal joint of variable disability depending on whether dorsal or plantar (more severe) instability.
