Resumen:
Femoroacetabular impingement (FAI) syndrome is a frequent cause of pain
and in recent years considered to be a precursor of premature hip
osteoarthritis. The structural abnormalities which characterize FAI
syndrome, such as the cam-type deformity, are associated with
morphological alterations that may lead to hip osteoarthritis. The aim
of this study was to determine the prevalence and topographic and
morphometric features of the cam deformity in a series of 326 femur
specimens obtained from a Mexican population, as well as changes in
prevalence in relation to age and gender. The specimens were subdivided
into groups according to gender and age. A standardized photograph of
the proximal femur of each specimen was taken, and the photograph was
used to determine the alpha angle using a computer program; the location
of the lesion was determined by quadrant and the morphometric
characteristics were determined by direct observation. The overall
prevalence of cam deformities in the femur specimens was 29.8 %
(97/326), with a prevalence by gender of 35.2 % (64/182) in men and
22.9 % (33/144) in women. The mean alpha angle was 54.6A degrees +/-
8.5A degrees in all of the osteological specimens and 65.6A degrees +/-
7.5A degrees in those specimens exhibiting a cam deformity. Cam
deformities were found topographically in the anterior-superior quadrant
of the femoral head-neck junction in 86.6 % (84/97) of the femurs.
Deformities were found in 28.2 % of the right femurs and 31.3 % of the
left femurs. The prevalence of cam deformity was higher in the femur
specimens of young men and in those of middle-aged and older women.
There were no significant differences in this deformity in relation to
the alpha angle according to age and gender.
