Metal-on-metal hybrid surface arthroplasty: two to six-year follow-up study.
BACKGROUND Following the reintroduction of metal-on-metal articulating surfaces for total hip arthroplasty in Europe in 1988, we developed a surface arthroplasty prosthetic system using aExpand
A systematic approach to the plain radiographic evaluation of the young adult hip.
Orthopaedic evaluation of hip pain in the young adult population has undergone a rapid evolution over the past decade1,2. This is in large part due to enhanced awareness of structural hip disorders,Expand
Prevalence of cam-type femoroacetabular impingement morphology in asymptomatic volunteers.
BACKGROUND Femoroacetabular impingement is a cause of hip pain in adults and is a possible precursor of osteoarthritis, with the cam type of impingement being the most common. The purpose of thisExpand
The Effect of Cam FAI on Hip and Pelvic Motion during Maximum Squat
AbstractFemoroacetabular impingement (FAI) causes abnormal contact at the anterosuperior aspect of the acetabulum in activities requiring a large hip range of motion (ROM). We addressed the followingExpand
The Concept of Femoroacetabular Impingement: Current Status and Future Perspectives
Femoroacetabular impingement (FAI) is a recently proposed mechanism causing abnormal contact stresses and potential joint damage around the hip. In the majority of cases, a bony deformity or spatialExpand
Three‐dimensional computed tomography of the hip in the assessment of femoroacetabular impingement
Femoroacetabular impingement secondary to the cam effect is thought to be associated with an insufficient anterior concavity in the sagittal/axial plane of the femoral head‐neck junction. UsingExpand
Femoroacetabular impingement alters hip and pelvic biomechanics during gait Walking biomechanics of FAI.
Femoroacetabular impingement (FAI) has been reported to cause hip pain in a variety of daily activities including walking. However, the biomechanics of level gait has not been compared between FAIExpand
Validity of the Alpha Angle Measurement on Plain Radiographs in the Evaluation of Cam-type Femoroacetabular Impingement
BackgroundCam-type femoroacetabular impingement is secondary to lack of concavity at the anterosuperior femoral head-neck junction, resulting in reduced femoral head-neck offset and femoral headExpand
Radiographic Evaluation of the Hip has Limited Reliability
AbstractRadiographic evaluation provides essential information regarding the diagnosis and treatment of musculoskeletal disorders. We evaluated the ability of hip specialists to reliably identifyExpand
Lower limb biomechanics during gait do not return to normal following total hip arthroplasty.
Although total hip arthroplasty (THA) is known to be a successful surgical procedure to alleviate hip pain and to improve health-related quality of life, these outcome measures in THA patients do notExpand
