Abstract:

An 84-kg, 9-month-old, entire male Mastiff presented for an angular limb deformity of the left pelvic limb. Clinical signs had been present for several months and a trauma to the distal tibial physis was suspected to be the underlying cause. Computed tomographic imaging noted a valgus of the left distal tibia. The degree of angulation was calculated first digitally, and the surgery rehearsed using specialized 3D imaging software, and repeated using a 1:1 scaled 3D printed model. Treatment was performed using a 3.5 broad tibial plateau levelling osteotomy locking-compression plate, placed in a novel fashion. The deformity was corrected and the osteotomy progressed to healing without complication.
