All right we are looking at the medial bone of your leg so the lower limb the leg you have
paired bones just like you do in terms of your upper limb or your your forearm region so whereas you have the radius and ulna here you're gonna have the tibia and the fibula which is
the lateral bone the tibia in comparison to the fibula is considerably more robust this is really
the weight-bearing bone the fibula has very little to do with in terms of weight-bearing it's more
of a muscle attachment site so we're looking at an anterior view here and one of the first
things I want you to note and this the shaft of the body portion of the tibia is this line right
here and you can actually palpate this through on yourself it's really fairly close in terms of
the skin so we considered this subcutaneous and you can palpate the tibia the entire way down
all right so let's look at a superior view of the tibia and you can see you have these very
shallow condyles this is going to be your medial condyle and your lateral condyle now how you know
that this is medial if you have an entire tibia is that you'll have the medial malleolus or malleolus
here so what's going to articulate here we know we're talking superiorly we're very shallow this
is going to be the inferior portion of your knee joint so your femoral condyles will articulate
here and this will be a portion of your knee joint so this whole region right here is referred to as
the tibial plateau and then you'll have the two condyles right here now right in the middle of
the condyles you'll have what we referred to as your intercondylar eminence this is where you're
going to have attachment of your ACL and your PCL ligament so your anterior cruciate ligament
and then criss-crossing that you'll have your posterior cruciate ligament so typically if
you have some type of injury it typically occurs at your ACL and you might have a tear away from
your intercondylar eminence all right so let me move this back more into anatomical position so
here's your superior and inferior portions and you'll have this robust region under the tibial
plateau referred to as the tibial tuberosity and this is where that patellar ligament or
the most inferior portion of your quadriceps femoris tendon attaches so we know about right
here is where your patella is going to be located because the patella is a sesamoid bone that forms
within this quadriceps femoris tendon all right let's flip the bone over so anterior now we're
going posterior and one thing I want you to note here is this building up in the superior portion
of bone this is what we refer to as your soleal line and as the name would indicate your soleus
muscle so very important in terms of plantarflexing or being able to stand on your toes your
soleus muscle is going to attach here all right now we're moving to the inferior portion of the
bone and as you can see you have a very shallow and smooth area this is going to articulate with
your superior most tarsal bone or your talus or talus bone all right so important in terms of
forming your ankle joint the last thing of note so I flipped back over to an anterior view is
your medial malleolus all right so if you were to feel your ankle if you're feel the medial
portion of your ankle this is what you're feeling your medial malleolus and then if you recall in
the video for the fibula you're going to have a lateral malleolus so that's what you can feel on
the lateral side so if you're just looking at this bone why don't we try to estimate if this is a
right or a left okay so we know this is medial so this is going to have to be a left tibia because
this is going to be medial and you'll have your medial condyle right here in the superior portion
