Orthopedic External Fixation system
The screw orthopedic is inserted into the bone near the fracture, and the fracture is fixed with an External Fixator assembled by a chuck and a nail rod.
Indications
open fracture, nonunion, closed fracture with extensive soft tissue injury, fracture with multiple trauma, osteotomy and correction.
The use of orthopaedic external fixators is currently a superior fracture fixation technique, filling the gap between cast and internal fixation. At the same time, Orthopedic External Fixator has the characteristics of simple fixation method, stable, reliable and effective, and does not limit the joint movement, can be early ambulation advantages. It can reduce the time for the operator and is more friendly to the user. The external fixator was used together with the bone traction needle. In terms of the classification of orthopedic external fixators, it is mainly divided into four types: orthofix type external fixation, ilizarov type external fixation, ao synthes type external fixation,combined external fixator and common external fixators.
The external fixators in orthopaedics was used for reduction (shortening and overlapping displacement were corrected first, then lateral and angular displacement were corrected, and finally rotational and separation displacement were corrected; If closed reduction is difficult, open reduction can be considered, but the separation of soft tissue and peeling of periosteum should be minimized.
The selection of the insertion site.According to the anatomical characteristics of the soft tissue at the insertion plane, the important nerves, vessels and tendons should be avoided; The ideal entry point is the part of the bone close to the subcutaneous, in a word, generally choose the skin and bone between the muscle soft tissue is the weakest point into the needle. The installation shall facilitate observation and control of soft tissue damage, and permit any surgery that may be required, such as repair and reconstruction, dressing change, skin grafting, or bone grafting." According to the location of the bone, different diameters of the threaded needle were selected. Removal was performed after completion of late treatment.
