The role of the tibia is mainly to bear the weight of the body as well as to form the main motor joints of the body to accomplish joint movements and so on. The tibia is one of the two bones of the lower leg, located on the medial side of the lower leg, and can be divided into one and two ends. The tibial stem is a typical tubular bone, with obvious cortex on both edges and a marrow cavity on the inner side. Due to its thickness, the tibia has a major role in weight bearing, and it can be said that 5/6 of the body weight is borne by the tibia, and the remaining 1/6 is borne by the fibula. The proximal end of the tibia and the distal end of the femur form the knee joint, allowing the knee to accomplish flexion and extension. The distal end forms the ankle joint with the talus and fibula, allowing the ankle to perform flexion, extension, inversion and eversion. Tibia related diseases should be timely to the hospital, complete the relevant examination, after a clear diagnosis, follow the doctor’s instructions for treatment, do not do it on your own, so as not to delay the condition.
