Tibia (shin bone)
The tibia and fibula are the lower leg bones that together form a proximal joint (proximal tibiofibular articulation) and distally surround the talus as the malleolar fork in the ankle joint. Both bones are connected by a stable membrane(interosseous membrane). Proximally, the tibia in the knee joint articulates with the femur, on which the patella is also flexibly supported without articulation with the tibia(femoropatellar sliding bearing)
Membrana interossea cruris
The stable connective tissue structure that connects the tibia and fibula over almost their entire length, except for a small recess for the passage of blood vessels. In addition to securing the two bones against lower leg-longitudinal translation, various muscles (in addition to their bony insertions) attach to the membrane:
