 The Tibia bone shinbone is located in the leg, itis the most frequently fractured bone in the body and has very poor blood supply because it is surrounded by skin and fat instead of muscle like the thighbone causing healing problems. Problems frequently found during the healing process are malunion bone heals in the wrong place, nonunion the bone never heals, and compartment syndrome a big inflammation of muscle that causes compression of nerves and blood vessels with necrosis death of tissue. Surgeons have tried to decrease these problems by using different surgical techniques and substances to accelerate healing. Substances frequently used in fractures are bone grafts. Bone grafts are normally obtained from the wrist or the hip bone, and sometimes can cause other complications varying from pain to infection. To avoid complications, investigators have used alternatives such as obtaining bone from donors. The donor bone grafts are carefully analyzed and cleaned to ensure they will not cause problems for the receiver. Bone obtained from donors is called Demineralized Bone Matrix DBM. DBM has proved to be very effective in helping fractures to heal faster and we want to use it in patients with tibia fractures.
