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 ...
When a bone fractures, the fragments lose their alignment in the form of displacement or angulation. For the fractured bone to heal without any deformity the bony fragments must be re-aligned to their normal anatomical position. Orthopedic surgery attempts to recreate the normal anatomy of the fractured bone by reduction of the displacement.
Implant that has been used for fixation of a broken wrist. Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation ...
Radiography to identify eventual bone fractures after a knee injury Orthopedic implants to repair fractures to the radius and ulna. Note the visible break in the ulna. (right forearm) Anterior and lateral view x-rays of fractured left leg with internal fixation after surgery
Some fractures, however, cannot be held in a satisfactory position by this method, and require some additional form of fixation. This is the usual situation with all displaced fractures of the first metacarpal and of the proximal phalanges of the hand, and of about two thirds of fractures of the distal end of the radius. Percutaneous pinning is ...
Orthopedic plates are designed based on the bone fracture. While the general design is similar, each plate must be manufactured to not only to reduce the fracture but also fit the contour of the patient's bone. [5] Protection Locking plates can be used either to support a locking head screw, or to force bone together at the fracture.
In medicine, the Ilizarov apparatus is a type of external fixation apparatus used in orthopedic surgery to lengthen or to reshape the damaged bones of an arm or a leg; used as a limb-sparing technique for treating complex fractures and open bone fractures; and used to treat an infected non-union of bones, which cannot be surgically resolved.
Indirect fracture healing, the most common type of bone repair, [10] relies heavily on endochondral ossification. In this type of healing, endochondral ossification occurs within the fracture gap and external to the periosteum. In contrast, intramembranous ossification takes place directly beneath the periosteum, adjacent to the broken bone’s ...
