Subchondral Bone Properties Of Cam-type Femoroacetabular Impingement Deformities

Evaluation of the Sclerotic Subchondral Bone Boundary as a Surgical Resection Guide in the Treatment of Cam-type Femoroacetabular Impingement

INTRODUCTION: Improper resection depth in the surgical correction of cam-type femoroacetabular impingement (FAI) has been identified as the most common reason for revision hip arthroscopy [1]. Under-resection fails to address patient symptoms and results in the need for revision arthroscopy [1], while over-resection may lead to iatrogenic femoral neck fracture, loss of the normal joint suction ...

Arthroscopic femoral osteochondroplasty for cam femoroacetabular impingement in patients over 60 years of age.

We reviewed the clinical outcome of arthroscopic femoral osteochondroplasty for cam femoroacetabular impingement performed between August 2005 and March 2009 in a series of 40 patients over 60 years of age. The group comprised 26 men and 14 women with a mean age of 65 years (60 to 82). The mean follow-up was 30 months (12 to 54). The mean modified Harris hip score improved by 19.2 points (95% c...

Statistical Shape Modeling of Cam-type Femoroacetabular Impingement

Cam femoroacetabular impingement (FAI) is characterized by a malformed femoral head that may cause shearing between the femur and acetabulum, leading to intraarticular damage and early hip osteoarthritis. Radiographic measurements are used to diagnose cam FAI, but provide only a planar view of the femoral head and often assume the ideal femur shape to be spherical. Statistical shape modeling (S...

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...
