Severe disability in primary osteoahritis of hip is best managed by –
**Core Concept**
Primary osteoarthritis of the hip is a degenerative joint disease characterized by progressive cartilage loss, subchondral bone sclerosis, and joint space narrowing, ultimately leading to severe disability. The management of this condition aims to alleviate symptoms, improve function, and delay or prevent joint replacement.
**Why the Correct Answer is Right**
Severe disability in primary osteoarthritis of the hip is best managed by **total hip arthroplasty (THA)**. This surgical procedure involves replacing the damaged joint with an artificial one, consisting of a metal ball and a plastic socket. THA provides pain relief, restores function, and improves quality of life. The success of THA is attributed to the elimination of the diseased joint, allowing for proper biomechanics and weight distribution.
**Why Each Wrong Option is Incorrect**
**Option A:** Conservative management, including physical therapy, bracing, and pain medication, is not sufficient to manage severe disability in primary osteoarthritis of the hip, as it does not address the underlying joint damage.
**Option B:** Hip resurfacing is a surgical option, but it is generally reserved for younger patients with severe osteoarthritis, as it is not as effective as THA in improving function and reducing pain.
**Option C:** Osteotomy, a surgical procedure that involves cutting and realigning the bone, is not a suitable treatment option for primary osteoarthritis of the hip, as it does not address the cartilage loss and joint damage.
**Clinical Pearl / High-Yield Fact**
It is essential to consider the patient's age, activity level, and overall health when deciding between conservative management and surgical intervention for primary osteoarthritis of the hip.
**Correct Answer: C. Hip resurfacing is generally reserved for younger patients with severe osteoarthritis, as it is not as effective as THA in improving function and reducing pain.
