Abstract:
Using THA as a proxy for underlying osteoarthritis, we describe population-based familial clustering of osteoarthritis of the hip. The GIF test for excess relatedness on 1049 patients that underwent THA (and do not have a diagnostic code for other conditions leading to THA) showed excess relatedness (P<0.001). Even when close relationships were ignored (closer than third-degree relationships), excess relatedness was observed (P=0.020). Relative risk was elevated in first-degree (RR 2.59; 95% CI 1.84-3.53, P=2.0e(-7)), second-degree (RR 1.66; 95% CI 1.11-2.39; P=0.0075) and third-degree relatives (RR 1.46; 95% CI 1.17-1.81; P=5.7e(-4)). Excess relatedness of individuals who had undergone THA for osteoarthritis and elevated risks to both near and distant relatives were observed.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
