Answer: Where the bone broke.There are three primary types of bone: woven bone, cortical bone, and cancellous bone. Woven bone is found during embryonic development, during fracture healing (callus formation), and in some pathological states such as hyperparathyroidism and Paget disease. It is composed of randomly arranged collagen bundles and irregularly shaped vascular spaces lined with osteoblasts. Woven bone is normally remodeled and replaced with cortical or cancellous bone.
Answer: the tibia is commonly referred to as the shin bone- if fractured at the distal end, it would involve the ankle- immobilization w/ a splint (casting) is the usual treatment. A tibial fracture at the proximal end -near the knee is more complex and may require surgery. All fractures of bones require immobilization of the affected portion to heal initially.
