Abstract
There is evidence that Femoroacetabular Impingement (FAI) is a major aetiological factor in end stage Osteoarthritis (OA) of the hip, particularly in the young adult. These patients are usually very active who suffer with persistent or intermittent groin pain. Recent studies have found that the majority of these investigated cases have evidence of mild bone abnormalities. These deformities can occur on either the pelvic or femoral side or a combination of both. They interact to reduce the amount of clearance between the femoral neck and acetabular rim. This results in repetitive early contact between these osseous prominences which if left untreated will eventually progress to OA. This study reviews the clinical presentation, diagnosis and research with regard to FAI. Significant findings include the confirmation that there are gender differences in FAI morphology as well as a strong correlation between the clinical diagnosis of FAI with motion simulations and the soft-tissue damage observed intra-operatively. However, it has been shown that FAI morphology is common within the normal population and presence of this morphology alone does not necessarily mean that subjects will experience motion restriction or joint degeneration. Consequently, the type and intensity of activity a person undertakes as well as presence of more than one radiological indication of FAI contribute to the progression towards OA. Further, the analysis of the activities that a person with FAI undertakes must consider the motion of the pelvis as well as the relative alignment of the femur and pelvis in the neutral posture. These factors along with the bone morphology dictate whether impingement will occur as well as its overall severity. This should be the basis of further development with regard to the motion analysis and simulation of FAI patients to obtain a more accurate diagnosis which the surgeon can respond to have a more effective surgical plan.
