![]() Tibial tuberosity – Between the condyles and the shaft, you’ll notice a bump on the anterior side of the tibia called the tibial tuberosity.This structure includes a left and right tubercle, which resembles tiny devil horns, and fossae, to which the menisci and the cruciate ligaments attach. Intercondylar eminence – Between the articular surface of the medial and lateral condyles is an area called the intercondylar eminence.This is going to articulate with the medial and lateral condyles of the femur (thigh) bone, forming the tibiofemoral joint. These are called the articular surface of the medial and lateral condyles. Articular surface of medial and lateral condyles – The top of these condyles have a concave surface, which you can see on the posterior view of the tibia. ![]() Medial is a directional term that tells us it is toward the midline of the body, and lateral means away from the body’s midline. A condyle is a rounded projection on a bone that is going to articulate (or form a joint) with something. Medial and lateral condyles – The proximal end (or top) of the tibia widens out from the shaft and forms a medial and lateral condyle.The tibia’s larger size allows it to transfer weight from the femur to the foot. In fact, this bone gets its name from a Latin word that literally means “shinbone.” When you feel your shinbone, this is what you’re feeling. Now let’s look at the tibia bone, which is the larger of the two leg bones, located medially. It also separates muscles on the anterior and posterior parts of the leg. This membrane keeps the tibia and fibula together and provides strength and stability for them. (Note, the radius and ulna bones also have this membrane.) So this is literally the membrane between the bones. The prefix “inter” means between, and osseous refers to the bones. Also, little starts with the letter “l,” which can help you remember that this bone is always on the lateral side.įirst, you’ll notice this web-like structure called the interosseous membrane (or middle tibiofibular ligament). If you get these two bones mixed up, here’s a quick memory trick: remember the phrase “never tell a little fib.” The fibula is the smaller of the two bones, so “little fib” will help you remember that it is the small one. ![]()
