Plain-English summary
In this study, researchers looked at two pets with a rare type of hip dislocation called caudoventral coxofemoral luxation, which is when the hip joint is out of place in a downward and backward direction. They used a special surgical technique called the modified Knowles toggle pin to fix the dislocation in both a cat and a dog. The cat recovered well within three days after the surgery, but the dog had ongoing issues, including severe limping and pain about two and a half months later, which led to the discovery of a fracture in the femoral head (the top part of the thigh bone). After performing another surgery to remove the damaged part of the bone, the dog was able to recover and regain function. Overall, the treatment worked well for the cat, while the dog needed additional surgery to fully recover.
Abstract
The coxofemoral joint is the most commonly luxated joint in dogs and cats. Coxofemoral luxations are generally craniodorsal; caudoventral coxofemoral luxations are relatively rare occurrences and may be accompanied by fracture of the greater trochanter. The aim of our study was to report the results of a modified Knowles toggle pin application in two caudoventral hip luxations for which closed reduction had not been achieved. Medical records of dogs and cats, which had been presented at our institution between September 1999 and October 2007, were reviewed for cases of coxofemoral luxation. In total, the case records of 67 cats and 147 dogs were found. Of these cases, there was one cat and one dog with caudoventral coxofemoral luxation. For both cases, the toggle pin technique was the method of treatment. The cat had a good clinical recovery within three days after surgery. The dog, which also had a cruciate ligament rupture in the same limb and medial patellar luxation in the contralateral limb, was presented with severe lameness and pain approximately two and a half months after surgery, at which time fracture of the femoral head was diagnosed. Functional recovery was achieved after a femoral head and neck ostectomy had been performed.
