Young dogs that show hip pain early in life (usually 6-12 months of age) that have no evidence of osteoarthritis (degenerative joint disease) on pre-operative radiographs (X-rays) may qualify for a triple pelvic osteotomy (TPO). What are the treatment options for hip dysplasia?ĭepending on your pet’s age, physical condition, and degree of hip pain/lameness, there are several surgical treatment options. The head of the femur (arrow) is seated deeply within the acetabulum, indicating excellent hip joint congruity. Radiographs (X-rays) of a normal dog’s pelvis and hips. Many dysplastic dogs will show these signs early in life (6-12 months of age), but some dogs do not show signs of pain until they are older. Owners report that their dogs are lame after exercise, run with a “bunny-hopping” gait, are reluctant to rise or jump, or aren’t as active as other puppies. If left untreated, dogs with hip dysplasia usually develop osteoarthritis (degenerative joint disease).ĭogs with hip dysplasia commonly show clinical signs of hind limb lameness, pain, and muscle wasting (atrophy). This laxity causes stretching of the supporting ligaments, joint capsule, and muscles around the hip joint, leading to joint instability, pain, and permanent damage to the anatomy of the affected hip joint. The abnormal development of the hip joint that occurs in young dogs with dysplasia leads to excessive hip joint laxity (looseness). There is no single cause of hip dysplasia rather it is caused by multiple factors, some of which include genetics and nutrition. It occurs commonly in large breed dogs such as Labrador retrievers, German Shepherds, Rottweilers, and Saint Bernards, but it can occur in dogs of any breed and size, and even in cats. Paediatric hip ultrasound is of less value in children aged less than 6 weeks (due to immaturity of joint formation) or those aged over 6 months (where femoral ossification can prevent adequate visualisation of the acetabulum).Canine hip dysplasia is the abnormal development and growth of a dog’s hip joint. What are the relative contraindications for a paediatric hip ultrasound for DDH? Previous unsatisfactory examination because of femoral head ossification. What are the absolute contraindications for a paediatric hip ultrasound for DDH? ![]() In Australia, the hip ultrasound study is only carried out if there are risk factors or an abnormal clinical examination. Some countries have hip ultrasound screening programs where all children are examined with hip ultrasound soon after they are born. What are the prerequisites for having a paediatric hip ultrasound for DDH done? Hip ultrasound should also be carried out when there are risk factors breech presentation, oligohydramnios, neuromuscular disorders or a family history of DDH in a first-degree relative. Asymmetry of the thigh skin folds can be seen in DDH and is a further indication for referral. The primary indication for hip ultrasound is the detection of hip laxity or ‘clicky hips’ in infants, usually around the time of the 6 week check-up after delivery. ![]() percutaneous transhepatic cholangiogramĪuthor: Dr Timothy Cain* What are the generally accepted indications for paediatric hip ultrasound for DDH?.18-20 week screening pregnancy ultrasound.
