Internal fixation for the treatment of multiple physeal tibial fractures in a growing dog

Abstract

This case report describes pinning fixation for the treatment of three tibial physeal fractures in a 3-month old mixed-breed dog. The radiographic study revealed a severe proximal dislocation of the tibial diaphysis along with multiple, closed fractures of the proximal and distal tibial physes, distal femoral physis and the fibula. Open reduction and internal fixation (ORIF) were performed using crossed Kirschner wires for proximal and distal tibial physeal fixation and a tension band to manage the tibial tuberosity avulsion fracture. Postoperative radiographs showed proper fracture reduction, tibial alignment and correct implant positioning. Clinical and radiographic checks documented progressive limb weight-bearing, gradual resolution of distal limb oedema and fracture healing. The described open surgical treatment had a satisfactory clinical outcome with restoration of tibial anatomy, preservation of joint function and an early return to normal motor activity at 45 days of follow-up.
