A 3 1/2 year old mixed breed dog presented to the orthopedic service in May for a consultation regarding a Total Hip replacement (THR) of the left coxofemoral joint. The patient displayed a “bunny hopping gait” as a puppy and had been lame for 6 months prior to presentation. The patient was previously managed medically for the lameness by the owner’s referring veterinarian. An orthopedic exam revealed bilateral crepitus in the hips. Radiographs confirmed a diagnosis of bilateral hip dysplasia. The patient was taken to surgery and a total hip replacement was performed using a BFX Bio-Medtrix cementless total hip system. The surgery did not have any complications and the recovery from anesthesia was uneventful. The patient was discharged two days later with instructions for a 12 week physical therapy protocol. At 16 weeks post-surgery the owner reports the patient has made a full recovery and has full range of motion of both hips with no lameness present.
