Lay Summary (English)

Lay summary
Osteoarthritis is one of the leading musculoskeletal causes of pain and disability. A decreased anterior offset i.e. a decreased difference between the anterior contour of the head and the femoral neck may result in repetitive damage of the peripheral articular cartilage of the hip joint during flexion and internal rotation, a phenomenon referred to as femoro-acetabular impingement. Cam type impingement, which is usually seen in men, is caused by the presence of a femoral neck protuberance with a non-spherical femoral head. Impingement can subsequently lead to osteoarthritis. Although several risk factors for femoro-acetabular impingement have been identified (e.g. fractures, surgery) most of the patients with femoro-acetabular impingement seen in orthopedic surgery lack a history of known predisposing factors. Previous studies suggest that femoral head and neck abnormalities develop during organogenesis.

To determine
• whether ‘cam’ type femoro-acetabular impingement clusters in families
• whether clustering is related to common risk factors or to genetic susceptibility
• how genetic susceptibility may be inherited

This project will help to understand the etiology of osteoarthritis. Patients with primary osteoarthritis are usually young with a considerable capacity to loose disability adjusted life-years. The identification of risk factors may help to develop additional treatment options including preventive interventions.
