Luxation of the long digital extensor tendon as a complication to Tibial Plateau Levelling Osteotomy. A presentation of four cases.

Abstract

Cranial cruciate ligament disease in dogs is frequently treated with Tibial Plateau Levelling Osteotomy (TPLO). Herein we describe four cases of dogs presenting with sudden lameness in the operated leg one to 12 months post TPLO surgery. On examination, all of the dogs had a luxation of the long digital extensor tendon (LDE) resulting from the TPLO surgery. All of the dogs underwent revision surgeries. The LDE tendon was either secured in its normal position or transected, and a tenodesis was performed. The dogs recovered well after surgery and lameness was resolved in all four cases.
