A variety of surgical methods is available for definitive fixation. After soft tissue swelling . The most common cause is trauma, followed by diseases (e.g., osteoporosis) that result in weakened bone structure.The latter results in pathologic fractures, which are fractures that would not usually occur if the bone structure was not weakened. AO Principles of Fracture Management is an essential resource for orthopedic trauma surgeons and residents in these specialties. External Fixators. 4.

AO publishing Donald L. Piermattei, Gretchen L. Flo and Charles E. Decamp. The Hybrid Ring Fixator is designed for fixation of complex proximal and distal tibial fractures, particularly those involving the joint, when: • soft tissue injuries preclude open reduction and internal fixation, or • the fracture pattern does not allow placement of Schanz screws for construction of a standard external fixator frame. ( From - \"AO Fundation\" ) Intramed. Radius, distal—intra-articular fracture. fixation methods demand that the plates be placed on the ten-sion side of the fracture so that fracture compression is assured and excess gap motion is prevented.8 Secondary bone healing (enchondral ossification) oc-curs when relative stability is provided and strain is kept be-tween 2% and 10%. - General theory and . In acute fracture care, its use is separated into two categories: provisional and definitive. Such fixation allows the soft-tissue envelope to stabilize before internal fixation. The third edition of the book has been fully updated and extended to describe the latest techniques and covers the complete content of the AO Principles Course of today. Provisional fixation is further subdivided into "damage control" and periarticular fracture stabilization. Corrective osteotomy and fixation with the 2.4 LCP distal radius T-Plate using the Henry approach. •percutaneous pinning •external fixation open reduction indications •operative reduction of the fracture is indicated: 1.when closed reduction fails 2 . make 2 cm incisions between the 2-3 and 4-5 dorsal compartments. Fourth edition. It is rapidly applied without need for intraoperative x-rays and can be adjusted later. Unless outlined in supporting instructional information, each External Fixation System is designed as a system and does not allow the substitution of components from other systems or manufacturers. Others may elect to stage the procedures or fix both fracture complexes at once. Treatment is based on which metacarpal is involved, location of the fracture, and the rotation/angulation of the injury. Physicians have been using external fixation to treat fractures for more than 2000 years after being first described by Hippocrates as a way to immobilize the fracture while preserving soft tissue integrity. 2.
