据有无生物学反应对长管状骨骨折后形成的假关节进行分类。轻度和高度肥大的假关节属于有生物学反应型,而坏死型和皮质骨缺损型假关节属于无生物学反应型骨不连。假关节的形成是因为骨折愈合调控系统,包括骨再生机制、骨微循环及骨折端的稳定性,遭受了严重干扰及破坏。调控系统遭到破坏的主要原因是具有生物学重要功能的骨膜、皮质骨和骨髓腔结构大量破坏。骨折愈合调控系统的破坏可来自创伤本身,但大多数是因为忽视了骨折愈合的基本生物学规律,手术处理不当造成手术中保护骨膜、皮质骨、骨髓腔结构免遭破坏是促进骨折愈合最重要的生物学法规。
There is no biological response to the long tubular fractures formed after the pseudarthrosis classification. Mild and highly hypertrophic pseudoknotics are biologically reactive, whereas necrotic and cortical bone prostheses are non-biologically reactive. The formation of pseudarthrosis is due to fracture healing control system, including the mechanism of bone regeneration, bone microcirculation and the stability of the fracture side suffered serious disruption and destruction. The main reason for the damage to the regulatory system is the extensive destruction of periosteum, cortical bone and marrow cavity structures with important biological functions. Fracture healing control system can come from the trauma itself, but most of them ignore the basic biological rules of fracture healing. It is most important to promote the fracture healing by protecting the periosteum, cortical bone and the structure of the bone marrow cavity during surgery by improper operation Biological regulations.
