Khảo sát tỷ lệ trật khớp xương chậu đùi ở chó và ứng dụng kỹ thuật cắt đầu, cổ xương đùi trong điều trị tại Bệnh viện Thú y Newpet, Thành phố Hồ Chí Minh

Coxofemoral dislocation, a prevalent orthopedic condition in dogs, significantly impacts their mobility and overall quality of life. Effective treatment strategies are crucial to address this debilitating issue. This study highlights the importance of understanding the epidemiology of hip dislocations in canine populations and evaluating surgical interventions. Specifically, it focuses on the application and outcomes of Femoral Head and Neck Ostectomy (FHNO) as a therapeutic approach in a clinical setting, aiming to provide valuable insights into its efficacy and suitability for veterinary practice, particularly in regions like Vietnam where comprehensive data may be limited.

Veterinarians, veterinary surgeons, orthopedic specialists, veterinary students, and researchers focusing on canine orthopedic conditions and surgical interventions.

This research comprehensively investigated the prevalence and treatment outcomes of coxofemoral dislocation in dogs at Newpet Veterinary Hospital, Ho Chi Minh City, from December 2022 to December 2023. Out of 2,436 surveyed dogs, 32 cases (1.13%) were diagnosed with hip dislocation, revealing a notable incidence. The study identified key epidemiological patterns, showing that coxofemoral dislocation was most common in adult dogs aged 6 months to 3 years and disproportionately affected small dog breeds weighing less than 9kg. Predominantly, cases involved craniodorsal unilateral dislocation, with common causes being traffic accidents and falls from height. The study then applied Femoral Head and Neck Ostectomy (FHNO) to 19 dogs with the condition. Post-surgical observations indicated an average recovery period of 58.07 days. While post-operative complications such as muscle atrophy, limb shortening, and reduced joint range of motion were noted, with only 54% of animals achieving satisfactory locomotion recovery, the procedure proved beneficial for pain management. Remarkably, 100% of the owners expressed satisfaction, attributing the surgical method to reduced pain and an improved quality of life for their pets. These findings underscore that FHNO is a viable option for managing coxofemoral dislocation, effectively mitigating pain and enhancing life quality, even if complete functional restoration is not always achieved. The study provides critical data for veterinarians, particularly regarding its practical application in Vietnam's clinical landscape.
