Tibia central portions of these facets articulate with the condyles of the femur, while their peripheral portions support the menisci of the knee joint, which here intervene between the two bones. Between the articular facets in the intercondylar area, but nearer the posterior than the anterior aspect of the bone, is the intercondyloid eminence ("spine of tibia"), surmounted on either side by a prominent tubercle, on to the sides of which the articular facets are prolonged; in front of and behind the intercondyloid eminence are rough depressions for the attachment of the anterior and posterior cruciate ligaments and the menisci. The
Tibia shaft fracture Tibia shaft fracture Tibia shaft fracture is a fracture of the proximal (upper) third of the tibia (lower leg bone). Due to the location of the tibia, it is frequently injured. Thus it is the most commonly fractured long bone in the body. Patients with tibial shaft fractures present with pain and localized swelling. Due to the pain they are unable to bear weight. There may be deformity, angulation, or malroation of the leg. Fractures that are open (bone exposed or breaking the skin) are common. Since approximately one third of the tibia lies directly beneath the skin, open fractures
