My name is Hannah Shaw, I'm
a reader at Cardiff University.
I'm going to be
giving you a talk
on the thigh,
gluteal region, and
knee joint. By the
end of the session,
0:11
by the end of the talk, you
should be able to describe
the anatomy of the gluteal
region of the thigh,
but also describe the
femoral triangle,
and explain its
clinical significance.
We also cover the anatomy
of the knee joint.
0:27
Firstly, we just need to think
about the functions
of the lower limb.
It is very important
in supporting the
weight of the body,
but also in locomotion, so
moving the body through space.
0:39
You have got the
bones of the hip,
the thigh, and the knee.
What we're going to do is
cover the basic osteology of
the region, so you
understand how everything is
built up and
developed around it.
The first thing you have
is the pelvic bone,
and this forms part
of the pelvis.
Firstly, we have
the pelvic bone,
and this is actually formed
by three separate bones,
the ilium, the ischium,
and the pubis.
We then have a long
bone of the thigh,
which is known as the femur.
Then two bones in the leg,
the tibia and the fibula.
We then have a small sesamoid
bone called the patella.
These contribute to the
joints of the lower limb,
which are essential
for locomotion.
1:21
These joints are the hip,
which is formed by the
contribution of the pelvic bone.
Here is the pelvic bone.
We have this deep fossa
here called the acetabulum.
The acetabulum is
quite a deep socket
into which this bulbous part,
the head of the femur fits.
This is a synovial
ball and socket
joint, which allows
a bit of movement
that allows a bit of
movement during flexion,
extension, abduction,
adduction during walking,
but it is actually quite
a stable joint because of
this deep socket and
the head of the femur
fitting into it.
It makes it quite stable, but
also permits a reasonable
amount of movement.
The hip joint is created by
the acetabulum and the
head of the femur.
