Sääreluuston

Sääreluuston refers to the bones of the lower leg in Finnish anatomy. This region is primarily composed of two long bones: the tibia and the fibula. The tibia, also known as the shinbone, is the larger and more medial of the two bones. It bears the majority of the body's weight and articulates with the femur at the knee joint and with the talus at the ankle joint. The fibula is a slender bone located lateral to the tibia. While it also articulates with the tibia at both its proximal and distal ends, and with the talus at the ankle, it plays a lesser role in weight-bearing and is more involved in providing muscle attachment and ankle stability.

The tibia has a prominent anterior crest, commonly referred to as the shin. Its proximal end features the tibial plateau, which forms the weight-bearing surface of the knee joint, and the tibial tuberosity, a roughened area where the patellar ligament attaches. The distal end of the tibia forms the medial malleolus, a bony prominence that contributes to the inner aspect of the ankle. The fibula, on the other hand, has a head at its proximal end that articulates with the tibia. Distally, the fibula forms the lateral malleolus, the bony prominence on the outer side of the ankle, which helps to stabilize the ankle joint and prevent excessive inversion. Together, the tibia and fibula form a strong and stable structure that supports the body's weight and allows for movement of the foot and ankle.
