对侧皮质锁定技术治疗骨折的研究进展

RESEARCH PROGRESS IN TREATMENT OF FRACTURES BY FAR CORTICAL LOCKING TECHNIQUE

目的对对侧皮质锁定(far cortical locking,FCL)技术治疗骨折的研究进展进行综述。方法查阅国内外有关FCL技术治疗骨折的文献,对其进行总结分析。结果为了克服传统锁定钢板(locking plate,LP)存在近钢板侧应力集中、刚度较高等缺陷,近来出现一种新的FCL技术。该结构保留了LP的整体固定强度,但降低了内固定物约80%的刚度,可提供骨折断端平行微动和形成对称的骨痂,在治疗骨折的理论、实验和临床应用等方面均取得令人满意的结果。结论 FCL技术是LP的一大改进,有望克服传统LP治疗某些部位骨折后骨折延迟愈合和骨不连发生率较高等缺陷。

Objective To summarize the research progress in the treatment of fractures by far cortical locking technique. Methods The domestic and foreign related literature about the treatment of fractures by far cortical locking technique was reviewed, summarized, and analyzed. Results In order to overcome the shortcomings of high stress at the near side of the plate and high stiffness of traditional locking plate, a new far cortical locking technique has been developed recently. The structure retains the overall strength of locking plate, but decreases the stiffness of the fixation by 80%, so it can provide interfragmentary parallel micromotion and help to form symmetric callus, and satisfactory results have been achieved in theory, experiment, and clinical application of treatment of fractures by far cortical locking. Conclusion The far cortical locking technique is a major improvement of locking plate, which is expected to significantly reduce delayed healing and nonunion of some fractures treated with traditional locking plate.
