Characteristics of internal fixation implantation in treatment of comminuted patella fracture / 中国组织工程研究

ABSTRACT

AIM: To analyze the characteristics of internal fixation implantation therapy for comminuted patella fracture. METHODS: A computer-based search of Pubmed database and Chinese Journal Full-text Database was undertaken, and the quotations of each literature were checked after the primary screening. Inclusion criteria the papers about the application of internal fixation materials in comminuted patella fracture, those published in authority journals within recent five years were preferred. Exclusion criteria repeated study or Meta analysis. RESULTS: Internal fixation approach differs as the fracture type. Tension band fixation is generally accepted to treat transverse patella fracture. Kirschner wire plus tension band fixation are inferior to transverse fixation, but in comminuted fracture it can induce more complications; despite of wide application, nickel titanium patella fixator is unsuitable for comminuted fractures due to its hypersensibility and carcinogenicity; silk or steel wire loop fixation fits various comminuted fractures, but metal cerclage is predisposed to induce infection and breakage because of insufficient fixation force. CONCLUSION: There is no common way for comminuted patella fracture therapy. Further researches on material and method which can cure all kinds of comminuted patella fracture are still needed.
