.Standring, Susan, editor. ''Gray’s Anatomy: The Anatomical Basis of Clinical Practice''. Forty-First edition, Elsevier Limited, 2016, p. 1327. Because the pelvic outlet in the female is larger than in the male, there is a greater distance between the greater trochanters in the female. It has two surfaces and four borders. It is a traction

epiphysis An epiphysis (; : epiphyses) is one of the rounded ends or tips of a long bone that ossify from one or more secondary centers of ossification. Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, inc ...

Surfaces

The ''lateral surface'', quadrilateral in form, is broad, rough, convex, and marked by a diagonal impression, which extends from the postero-superior to the antero-inferior angle, and serves for the insertion of the tendon of the gluteus medius. Above the impression is a triangular surface, sometimes rough for part of the tendon of the same muscle, sometimes smooth for the interposition of a bursa between the tendon and the bone. Below and behind the diagonal impression is a smooth triangular surface, over which the tendon of the

Borders

The ''superior border'' is free; it is thick and irregular, and marked near the center by an impression for the insertion of the piriformis. The ''inferior border'' corresponds to the line of junction of the base of the trochanter with the lateral surface of the body; it is marked by a rough, prominent, slightly curved ridge, which gives origin to the upper part of the

. The ''anterior border'' is prominent and somewhat irregular; it affords insertion at its lateral part to the gluteus minimus. The ''posterior border'' is very prominent and appears as a free, rounded edge, which bounds the back part of the trochanteric fossa.
