All right so we're looking at the thigh bone or your femur as you can see here this is going to
be the longest bone in the body now dependent on height it can be significantly long and you
can see in this particular individual this is on the smaller side in terms of a femur so in this
particular view we're looking at an anterior view this is going to be superior and the way that we
know that is that you have your femoral head so this is what's articulating with the acetabulum
of your coxal bone to form that ball and socket joint you have the shaft of your femur or the body
and then the inferior portion here you can see that almost the entirety of this is going to be
smooth because you're going to have articulation with the condyles of the tibia as well as on the
anterior portion right here you're going to have articulation with the patella or your kneecap
alright so you always know that this is anterior for your patella here so let's move back in terms
of the structures for the superior ones down to the inferior so I want you to recall when we're
talking about the humeral head how small it is in comparison to the femoral head so you have a
much better fit or better congruence between the femoral head and the acetabulum is in comparison
to the humeral head in the glenoid fossa of the scapula now as you continue you can see a pinched
in area right here we refer to this as the femoral neck so we've ever ever heard of the term a broken
hip it's typically right here that's actually being fractured so it's the femoral neck that's
actually the fractured area as opposed to the actual coxal bone now on either side you can see
the two trochanters the larger one that's going to be opposite to the humeral head so we know we're
talking lateral this is your greater trochanter and then more posteriorly place but also medially
placed you'll have your lesser trochanter and we'll see this one again when we flip the femur
over now one other thing we're moving all the way to the inferior portion you have your medial and
your lateral condyles of the femur the way that you're going to know which ones which is that
the medial is going to be on the same side as the femoral head and we know the femoral head
has to be medial in order to articulate with the coxal bone above each one of the condyles
you'll see these projections right here these were these are referred to as epicondyles your
lateral epicondyle and your medial epicondyle and this is where your tibial and fibular collateral
ligaments are going to attach now let's flip this over now we're looking at a posterior view
so superior inferior here's the femoral head the greater trochanter and like I said before you can
see your lesser trochanter a little better here so in terms of what's actually going to attach
to these trochanters you have a lot of muscles attaching on the greater trochanter that's why
it's larger than the lesser trochanter all the lateral rotators of the hips hip as well as your
piriformis which is probably the strongest in terms of your lateral rotators as well as
the gluteus medius and minimus so those deeper and smaller muscles as opposed to the greater
troch- or the gluteus maximus in terms of what's are attaching to the lesser trochanter is going
to be your iliopsoas muscle the iliopsoas muscle is a very powerful muscle very important in terms of
flexion of your hip joint so lesser trochanter is going to be iliopsoas now if you look at
the shaft and/or the body of the femur on the posterior side it's going to be a bit more complex
than on the anterior you're gonna have this line right here refer to as the Linea aspera and those
adductors or ADductors of the hip are all going to have an attachment here so if you think about
contracting those muscles they're going to pull the thigh back towards the midline so adduction
now we discuss these already in terms of the medial and the lateral condyle but you can see
these a little bit better here and how robust they are in comparison to the fairly shallow
condyles of the tibia so you have an incongruence here in terms of the knee joint that's why you
have all the surrounding muscle and ligaments that play such a big role in terms of the knee joint
