Abstract:
Method of fixation: - Carbon plate.- Carbon plate accompanied with IM nail. There have been previous several analysises of many respects. The report only analysed functional features of carbon plate in detail, based on 5 year experiences of using carbon plate for treatment of fractures. The ratio of stable union has reached an encouraging level. It is worth discussing the active and direct contribution of carbon composite material to the bone healing process. Fixation with carbon plate produces flexible fixation which is now considered to encourage. In terms of technique, it is not necessary to follow strictly the rules of rigid fixation. Two basic points have been performed adversely. Immobilization allows a little movement. A small gap still remains between the end of fractures. But the results are satisfactory: periostal bridging callus occurs early and popularly at the opposite site of the place where the carbon plate was put on (contrary to rigid fixation in which there is always the risk of destroying bone and bone graft is used as a rule in the case of complex fractures). The evaluation of results is different as well. In rigid fixation, periostal callus is a sign of failure. In flexible fixation (for example: using carbon plate) periostal callus which is block-shaped and bridged is a sign of good healing. In practice, there is correspondence between its occurrence on X-ray film and patient' s ability to function well. 30% of the cases removed carbon plate after bone healing have had newly made vessels on the bone surfaces under carbon plate. This proved that when contacting directly with fracture site, carbon plate encourages actively revascularization. The authors who recommended using metal plate to fix rigidly fractures site observed that "the bone zone under the plate is in osteolytic condition; cortical wall becomes cancellous bone and the zone potentially produces bone necrosis". In summary, carbon composite used to make plate for fixing bone fracture actively pushes up newly made vessel. This is the mandatory and most important criterion for bone healing. Brittle and breakable character can be overcome by changing pattern and combining carbon plate and IM nail as a short-termed move.
