Greater trochanter osteotomy as a component of cementless total hip replacement: Five cases in four dogs

To describe the surgical technique and report the long-term outcome of greater trochanteric osteotomy (GTO) as a component of cementless total hip replacement (THR) in dogs with severe medialization of the greater trochanter or chronic craniodorsal hip luxation.

Short case series.

Four dogs treated with five THRs.

Data collected from medical records included signalment, indication for THR, duration of clinical signs, body weight, pre- and post-operative radiographic assessment, surgical templating, osteotomy technique, THR implant selection, surgical time, complications, and long-term clinical and radiographic follow-up. Clinical outcomes were determined based on in-hospital history, orthopedic examination, and radiographic evaluation.

All five surgical procedures resulted in satisfactory long-term clinical results at follow-up a median of 48.2 months (range, 34-56 months) after THR. There were no minor complications and one major complication. One dog experienced post-operative luxation unrelated to the GTO and was successfully treated with a cup revision.

GTO was effective in facilitating cementless THR in dogs with either severe medialization of the greater trochanter or chronic craniodorsal luxation.
