säärelu

The word säärelu is an Estonian term that translates to "shinbone" or "tibia" in English. It refers to the larger of the two bones in the lower leg, located on the medial side. The tibia articulates with the femur at the knee and with the talus bone of the ankle. Its primary functions are to support body weight and to provide attachment points for muscles involved in movement of the ankle and foot.

The säärelu is a long bone and is characterized by its relatively thick shaft and its expanded ends. The proximal end, or upper extremity, forms the medial and posterior parts of the knee joint. The distal end, or lower extremity, forms the medial malleolus, which is the prominent bump on the inside of the ankle. This bone is crucial for locomotion and bears a significant portion of the body's weight during standing and walking.

Fractures of the säärelu can occur due to direct trauma, such as falls or impact injuries, or from stress fractures caused by repetitive strain. Because it is a superficial bone, it is also susceptible to open fractures where the bone breaks through the skin. Treatment for säärelu fractures varies depending on the severity and location of the break, and can range from casting to surgical intervention.
