A comparative study of patients with tibial shaft fracture underwent interlocking intramedullary nail postoperative between dynamization and non-dynamization / 重庆医学

ABSTRACT

Objective To prospectively compare the clinical outcome of dynamization and non-dynamization of interlocking intr-amedullary nail on union of tibial shaft fractures (fracture gap0 .05];16 weeks after internal fixation surgery ,VAS score of the dynamization group was statistically higher than that of the non-dynamization group [(4 .1 ± 0 .6) vs .(2 .3 ± 0 .8) ,t=16 .100 ,P<0 .05];the knee pain rate of the dynamization group was statistically higher than that of the non-dynamization group (28 .7% vs .12 .9% ,χ2 =5 .764 ,P<0 .05) .Conclusion When treating tibial shaft fractures with closed reduction and intramedullary nail fixation ,the main fracture gap<2 .0 mm ,early dynamization didn′t have any advantage .
