Reconstruction of Triceps Tendon Avulsion Using Mesh Graft and Krackow Suture in a Border Collie

Abstract

A 3-year-old, 24-kg intact female Border Collie was referred for a toe-touch weight-bearing stance, intermittent weight-bearing lameness, and mod-erate pain reaction of the right forelimb on physical examination and right hu-merus olecranon avulsion fracture on diagnostic imaging examination. Surgical repair was performed using tension band wiring to re-attach the triceps tendon and distal olecranon. Migration of the distal olecranon fragment was observed due to comminuted fracture of the fragment 5-days after surgery, and revision surgery was performed. The tension-relieving sutures were passed through the pre-drilled hole in the olecranon, and the polyester mesh was augmented to the suture region, covering the triceps tendon and olecranon drilling hole using the Krackow suture pattern. The elbow joint was immobilized using a type IA tran-sarticular external fixator, which was removed 8 weeks after surgery. Fourteen weeks after surgery, no lameness was observed on gait evaluation. At follow-up after 7 months, the distal olecranon fragment had stabilized, and no lameness was observed. © The Korean Society of Veterinary Clinics.
