Bone healing, or fracture healing, is a proliferative physiological process in which the body facilitates the repair of a bone fracture. Generally, bone fracture treatment consists of a doctor reducing (pushing) displaced bones back into place via relocation with or without anaesthetic, stabilizing their position to aid union, and then waiting ...
Stress fractures most frequently occur in weight-bearing bones of the lower extremities, such as the tibia and fibula (bones of the lower leg), calcaneus (heel bone), metatarsal and navicular bones (bones of the foot). Less common are stress fractures to the femur, pelvis, sacrum, lumbar spine (lower back), hips, hands, and writs. Stress ...
A stress fracture in the front of your tibia is one of this injuries that frequently requires surgery to heal. A metal rod placed down the center of the tibia is a commonly performed surgery for ...
This initial "woven" bone does not have the strong mechanical properties of mature bone. By a process of remodelling, the woven bone is replaced by mature "lamellar" bone. The whole process may take up to 18 months, but in adults, the strength of the healing bone is usually 80% of normal by 3 months after the injury. [citation needed]
Calcitonin has a greater effect in young children than in adults, and plays a smaller role in bone remodeling than PTH. [4] In some cases where bone resorption outpaces ossification, the bone is broken down much faster than it can be renewed. The bone becomes more porous and fragile, exposing people to the risk of fractures.

Of the three types of occult fractures mentioned above, the latter two, fatigue fracture secondary to repetitive and unusual stress being applied to bone with normal elastic resistance, and insufficiency fracture resulting from normal or minimal stress on a bone with decreased elastic resistance are also described as "stress fractures". [1]
Fracture strength, also known as breaking strength, is the stress at which a specimen fails via fracture. [2] This is usually determined for a given specimen by a tensile test, which charts the stress–strain curve (see image). The final recorded point is the fracture strength.
