00:00
So now let's move on
to the femur.
00:03
The femur, which is the thigh bone
within the thigh.
00:07
We can see here
we have an anterior right femur
and we have a
posterior right femur.
00:15
So here we have the anterior view
of the right femur.
00:18
We've got the
head of the femur here.
00:21
Its large,
its spherical,
and articulates with the acetabulum
at the hip joint.
00:27
It contains a depression medially,
which is the fovea here.
00:31
And this contains
the attachment site
for the ligaments of the head
of the femur.
00:36
The neck joints the head
to the shaft.
00:39
So here we can see
the neck of the femur
And it contains two trochanters.
A greater and the lesser trochanter.
00:47
And these are clearly seen
on the posterior view.
00:50
Running between the two trochanters
on this anterior aspect,
we have the intertrochanteric line.
00:57
And that's running between
the two trochanters
on this anterior aspect.
01:02
If we look at the shaft
and it's relatively dull,
it's smooth,
it's rounded on the anterior surface
posteriorly there's some features
we will mention.
01:13
Distally though
on this anterior surface,
we can see some femoral condyles,
we can also see passing
towards these condyles
the medial and lateral epicondyles.
01:24
And these are going to give rise
to those condyles
which articulate with
the tibial condyles,
and form the knee joint.
01:32
We can also see a smooth region here
and that is the patellar surface.
01:37
If we look at the
posterior view now of the femur,
we can still see we've got our head,
we've got our neck,
and we can see we've got
a great trochanter now
and clearly a lesser trochanter.
01:49
But here we can see we now have
an intertrochanteric crest.
01:54
We don't have that line.
01:55
Looking at the shaft, we can see
running down from these trochanters
we have the lateral and a medial lip
that forms the linear aspera.
02:05
Superiorly,
the lateral lip blends
with the roughened
gluteal trochanter
and the medial lip runs
to the lesser trochanter
as the pectineal line.
02:15
And we'll see some
important muscles attach here
like pectineus.
02:19
The medial tip becomes continuous with the spiral line,
whereas the area between the medial
and lateral tips forms the pectineal line.
02:29
So distally, we can now clearly see
a large femoral condyles.
02:35
We can still make out
the lateral epicondyle
and the medial epicondyle
will be on this side.
02:40
On the medial epicondyle,
we can see in adductor tubercle,
which has an important attachment.
02:46
But the femoral condyles,
medial and lateral,
they're separated by
this intercondylar fossa,
which will soon appreciate
contains some cruciate ligaments
and it articulates
with the tibial condyles
to form the knee joint.
03:01
On the medial condyle,
we can see we've got the
adductor tubercle here
and that's located on
the superomedial aspect
of that medial condyle.
