Femoroacetabular impingement causes pain in the hip in young adults and may predispose to the development of osteoarthritis. Genetic factors are important in the aetiology of osteoarthritis of the hip and may have a role in that of femoroacetabular impingement. We compared 96 siblings of 64 patients treated for primary impingement with a spouse control group of 77 individuals. All the subjects ...

Background: Femoroacetabular impingement (FAI) is pain due to shape mismatch at the hip joint commonly affecting young athletes, and there are 2 main types depending on which bone has underlying deformity: cam (femoral) pincer (acetabular). Hip arthroscopy an invaluable technique in sports surgeon repertoire, a need for comprehensive tutorial that elucidates best practices nuances. Indications:...

Groin problems in sports can be multifactorial and often a team approach between orthopaedic, general surgeons is required for both diagnosis and treatment. Both clinical disciplines can be the first point of contact for athletes looking for medical advice. Good communication between the members of a medical team looking after an athlete is essential and is not helped by the use of confusing te...

OBJECTIVES Femoroacetabular impingement is proposed to cause early osteoarthritis (OA) in the non-dysplastic hip. We previously reported on the prevalence of femoral deformities in a young asymptomatic male population. The aim of this study was to determine the prevalence of both femoral and acetabular types of impingement in young females. METHODS We conducted a population-based cross-sectio...

The radiological evaluation of the anterolateral femoral head is an essential tool for the assessment of the cam type of femoroacetabular impingement. CT, MRI and frog lateral plain radiographs have all been suggested as imaging options for this type of lesion. The alpha angle is accepted as a reliable indicator of the cam type of impingement and may also be used as an assessment for the succes...

This report describes the arthroscopic management of a case of incarcerating pincer-type femoroacetabular impingement. The hip joint had a marked restriction of range of motion and secondary pain as a result of osteophytes wrapping around the femoral head down the femoral neck. The patient was treated with staged bilateral hip arthroscopy. The procedures were initially performed through the per...

The etiology of degenerative joint disease of the hip remains unsolved. A precursor for some patients, especially younger ones, may be hip impingement. Repetitive microtrauma at maximal flexion can cause chronic pain from the abutment at the femoral head-neck junction caused by an abnormal offset. Chronic impingement from an aspherical head can lead to degenerative labral tears and acetabular c...

Young adults with hip pain secondary to femoroacetabular impingement (FAI) are rapidly being recognised as an important cohort of orthopaedic patients. Interest in FAI has intensified over the last decade since its recognition as a precursor to arthritis of the hip and the number of publications related to the topic has increased exponentially in the last decade. Although not all patients with ...

Background: Femoroacetabular impingement (FAI) syndrome, or hip impingement, is a musculoskeletal condition affecting the joint. It involves motion- position-related pain originating from an abnormal, premature contact between femoral head-neck junction (femur) and acetabular rim (rim around socket). Cumulative repetitive mechanical overloads at joint appear to contribute development of FAI. Ho...
