Abstract:

There are many methods for internal and external fixation of limbs fractures, such as plaster, splint, and traction. But the disadvantages such as destroyed local blood supply, unreliable fixation, inappropriate dynamic and static combination, postoperative nursing, delayed functional recovery and complications limit their application. Multifunctional external fixation apparatus has been used to treat limbs fractures. It avoids to dissect surrounding tissues and does not damage blood supply out of medullary cavity, which benefits wound treatment, early functional exercise, prevents joint adherence, improves cure rate, reduces complications and avoids second surgery. Moreover, this method is an effective fixation, saves treatment time and prevents adverse results due to treatment for other wounds. In addition, it can also be used to treat bone nonunion, infective fracture, bone defect and other fracture complications.
