The most plausible explanation is that a lack of constant physical activity causes the bone in the head of the femur
the long bone in the thigh to become thinner and lighter than those found in modern primates such as chimpanzees, gorillas and orangutans," explained Timothy M.
The procedure involves removing a tiny layer of bone off the head of the femur
and placing a cobalt chrome metal cap over it while a matching metal cup (similar to what is used in THR) is placed in the pelvis socket.
Prolonged scissoring or turned-in position of the legs may permit the head of the femur
to slide backward over the posterior edge of the hip socket.
The neck of the femur or the greater trochanter impinges on the rim of the acetabulum and thereby levers the head of the femur
out of the acetabulum through a tear in the anterior hip capsule.
The cephalomedullary nail is placed into the canal of the femur, and then the lag screw is placed through the nail and into the neck and head of the femur
They found evidence of deformity of the head of the femur
, leading to abnormal contact between the femur and the hip socket, in men and adolescents who played in an elite basketball club since they were eight years old.
In day 60, the head of the femur
was expelled from the acetabulum cavity.
Femur length (mm) was measured from the head of the femur
to the medial epicondyle and femur diameter (mm) was measured at the midpoint of the bone along the shaft in each rat.
The femoral stem is the hip prosthesis element that replaces the head of the femur
With the thumb on the inner side of the thigh, backward pressure is applied to the head of the femur
The surgeon instead reshapes the head of the femur
to fit a toadstool-shaped prosthesis--a metal cap that is snapped onto the femoral head and held in place via a relatively short stem that slips into the femoral neck.
The bones of the pelvis, the pubis, the ischium and the illium form a ball-socket joint together with the head of the femur
, the log thigh bone (fig.
