SOURCE
DEFINITION
TRAIT
Finnegan (1978)
Depression or eroded area where bone has been
lost, trabeculae must be exposed to be scored.
Allens Fossa
Buikstra Ubelaker (1994)
Extension of articular surface of femoral head
onto anterior-superior aspect of the neck,
covered by hyaline cartilage.
Poiriers Facet
Finnegan (1978)
Overgrowth or bony scar extending from area of
Poiriers facet to femoral neck, where it can
surround or cover Allens fossa.
Plaque
Kostick (1963)
Resembles Poiriers facet. Located on posterior
aspect of femoral neck.
