Femur
1. Femur
It is the longest bone of the body human body.
The head of the femur articulates with
the acetabulum in the pelvic bone forming the hip
joint, while the distal part of the femur articulates with
the tibia and kneecap forming the knee joint.
5. Complete structure of
femur…Proximal femur
The head contains a small
centred depression called
the fovea capitis (site of
attachment of ligament of
head of femur).
The greater trochanter and
lesser trochanter are
projections from the
junction of the neck and
shaft that serve as points of
attachment for the tendons
of some of the thigh and
buttock muscles
6. The greater trochanter is the prominence felt on the
widest part of your hip. It is commonly used to locate
the site for intramuscular injection o
The lesser trochanter is inferior and medial to the
greater trochanter o
Between the anterior surfaces of the trochanters is a
narrow intertrochanteric line
7. A ridge called the
intertrochanteric crest
appears between the
posterior surfaces of the
trochanters
8. Inferior to the intertrochanteric crest on the posterior
surface of the shaft of the femur is a vertical ridge
called the gluteal tuberosity, which blends into the
linea aspera. Both ridges serve as attachment points for
the tendons of several thigh muscles
9.
10. Distal Femur
The posterior border of the shaft of the femur forms a
broad roughened crest called as linea aspera.
At the distal end of the femur, the linea aspera forms
the floor of the popliteal fossa, and its margins form
the medial and lateral supracondylar lines which
terminate on the superior aspect of the condyles
(medial condyle is larger + more inferior)
11. The condyles are separated posteriorly by an inter-
condylar fossa. On each condyle is a shallow oblique
grove that separates the surface that articulates with
the tibia from the surface that articulates with the
patella.
