Disorder - Hip Dysplasia

Organ Systems Involved
Musculoskeletal

Alternative Names
Congenital dislocation of the hip
Acetabular Dystrophy

Brief Description
    Abnormal formation of the hip joint resulting in joint slackness, often leading to arthritis. In severe cases the dog may suffer lameness in the affected limb(s).

Presenting Signs
    Dogs with hip dysplasia may suffer this condition in one or both hips. Outward signs vary depending on the severity of the condition, which usually worsens over time. Initial signs are likely to be a slight change in gait and difficulty getting up from a lying or sitting position, or in climbing stairs. A reluctance to move the affected joint may also be observed, for example, an otherwise obedient dog may show reluctance to sit on command. It is common for an affected dog to adopt a 'bunny hopping gait' by which it moves both rear legs simultaneously while running. Signs of a more serious condition include obvious pain when the leg is extended or when weight is placed on it, obvious lameness and stiffness especially after strenuous exercise, and in the most severe cases, permanent lameness in the affected limb. Dogs with naturally looser hip joints are more likely to develop problems with hip dysplasia than those with more tightly constructed joints. Overweight dogs are more susceptible due to greater strain on their joints. Also a young, growing dog with the genetic makeup for hip dysplasia is more likely to develop arthritis and have more eventual difficulty if it is extremely active.
