Prevalence of coxofemoral dislocation in dogs and applying femoral head and neck ostectomy in treatment at Newpet veterinary hospital,

Abstract

The research project "Prevalence of coxofemoral dislocation in dogs and applying femoral head and neck ostectomy technique in treatment" was carried out at Newpet Veterinary Hospital, Ho Chi Minh City from December 2022 to December 2023, with the purpose of surveying cases of coxofemoral dislocation in dogs and evaluating the treatment effectiveness of femoral head and neck ostectomy. The studied result recorded that there were 32 cases of dogs with
coxofemoral dislocations with 35 dislocated joints out of 2,436 surveyed dogs, accounting for 1.13%. Dogs with coxofemoral dislocation commonly met in the adult dog group and accounting for the highest rate at age group from 6 months old to 3 years old. Small dog breeds weighing less than 9kg were more susceptible to dislocation than larger and heavier dog breeds. Most of the dogs had craniodorsal unilateral dislocation; and the most common causes of hip dislocation were by traffic accidents and falls from height, respectively. The study also applied the surgical technique of femoral head and neck ostectomy on 19 dogs with coxofemoral dislocation. The surgical results showed that animals were suffered with pain after surgery and were required to use painkillers continuously. The average recovery time for animals was 58.07 ±11.53 days after surgery with post-operative complications included loss of muscle mass, shortening of the surgical leg and reduced joint range of motion. Clinical evaluation showed that only 54% of animals met the requirements for locomotion recovery after surgery. However, 100% of the surveyed owners commented that they were satisfied with the results of surgical method, thanks to that it helped animals reducing pain and improving their quality of life.
