total hip replacement

total hip replacement,

a surgical procedure to correct a hip joint damaged by degenerative disease, often arthritis. The head of the femur and the acetabulum are replaced with metal components. The acetabulum is plastic coated to avoid metal-to-metal articulating surfaces. See also total hip arthroplasty, total joint replacement.

1. the region of the body around the articulation of the femur and the pelvis.

2. loosely, the hip joint.

hip bone

os coxae, which comprises the ilium, ischium and pubis. See also Table 10.

hip dislocation

manifested by inability to bear full weight on the limb, excessive mobility of the limb, crepitus at the joint, and in some cases shortening of the limb.

hip dysplasia (HD)

is manifested (1) radiographically by a shallow acetabulum, a small, misshapen femoral head and sometimes osteophyes, and (2) clinically, by a lax joint, weak rump muscles with or without lameness. In dogs inheritance has a degree of influence on the occurrence of the disease. See also degenerative joint disease.

hip flexion posture

posterior presentation of a fetus in the birth canal with the hocks flexed.

hip joint

the ball-and-socket joint formed between the head of the femur and the acetabulum of the pelvis.

hip laxity

subluxation of the coxofemoral articulation, a feature of hip dysplasia (above).

hip sling

a metal clamplike device used to lift a downer cow. Comprises two loops which fit over both iliac tuberosities (coxal tubers) and which are clamped together so that the cow is closely held. The sling is lifted with a block and tackle or by a frontend loader or hoist on a tractor.

total hip replacement

replacement of the femoral head and acetabulum with prostheses that are cemented into the bone; called also total hip arthroplasty.
