Preoperative And Postoperative Cycling Biomechanics Following Cam Femoroacetabular Impingement Corrective Surgery: A Pilot Study

Use of robotic technology in cam femoroacetabular impingement corrective surgery.

BACKGROUND Cam type femoroacetabular impingement (FAI) is an anatomical disorder that can lead to osteoarthritis (OA) of the hip joint. With existing surgical options there is invariably a tendency for under-resection or over-resection of the cam lesion, both having dire consequences. This study assessed the application of robotic technology in the surgical management of cam FAI. METHODS Thre...

The Biomechanics of Femoroacetabular Impingement

The Etiology of Cam-type Femoroacetabular Impingement: A Cadaveric Study.

BACKGROUND There is a dearth of literature examining the causes of cam-type femoroacetabular impingement (FAI) and when such morphology appears. The purpose of the current study was to analyze how the ossific portion of the proximal femur develops over time with respect to standard cam-type FAI parameters. METHODS A collection of 193 femurs from cadavers aged 4 to 21 years were evaluated. The...

Statistical shape modeling of cam femoroacetabular impingement.

Statistical shape modeling (SSM) was used to quantify 3D variation and morphologic differences between femurs with and without cam femoroacetabular impingement (FAI). 3D surfaces were generated from CT scans of femurs from 41 controls and 30 cam FAI patients. SSM correspondence particles were optimally positioned on each surface using a gradient descent energy function. Mean shapes for groups w...

Correlation Between Cam-Type Femoroacetabular Impingement and Radiographic Osteitis Pubis.

A mechanistic link has been suggested between cam-type femoroacetabular impingement and increased stress on the symphysis pubis. This retrospective study was conducted to determine whether there is an increased prevalence of osteitis pubis, as evidenced by imaging, in patients with femoroacetabular impingement compared with age-matched control subjects. Search of a radiologic database of a larg...
