The Meaning Of Screw Auxiliary In The Treatment Unstabletibial Fracture With Two Types Of Internal Fixation

Objective: the present study was designed to search the meaning of screw Auxiliary inthe treatment of dry unstable tibial fracture with two types of Internal fixationMethods: Sixty cases of tibial shaft fracture instability, treated from January2007toSeptember2012,were randomly divided into two groups, each group of thirty cases,onegroup were treated with Steel combination lock auxiliary fixing screws (L+L group), inthe groups, men sixteen cases, females fourteen cases, Age Thirty-six±five years of age,according to AO classification,fracture type A1nine cases, A2seven cases, B1eight cases,type B2four cases, C2type C2two cases;and another were treated with the fixation ofintramedullary nail combined with screws (P+L group),in the groups, men seventeencases, females thirteen cases, Age thirty-four±six years of age, according to AOclassification,fracture type A1thirteen cases, A2eight cases, B1six cases, type B2fivecases, type C2two cases.。observed two measured blood loss cases, operative time,healing time,and complications.Results: All patients were followed up for eighe months to two years and six months, anaverage of ten±two months, compared blood loss cases and operation time, P <0.05, twogroups was statistically significant;in the P+L groups,fracture healing time was fromeight months to eighteen months: the average healing time was8.0±2.6months:; in the L+L groups, fracture healing time was from six months to twenty-four months: theaverage healing time was8.05±2.4; t test inspected two independent samples,P>0.05,the two groups was not statistically significant.。 according to referenceJohner-Wruhsevaluation criteria[1], in the L+L groups, the efficacy of twenty-two cases were excellent,seven cases were good, good rate was93.33%; in the P+L groups,twenty-four caseswere excellent,five5cases were good, one case was suit,excellent rate of96,67%;compared two groups, P>0.05, two groups was not statistically significant.in the L+L group,one case occurred plate fracture, the complication rate was3.3%,the P+L grouphad no nail breakage fracture、fracture delayed healing and other complications.Conclusion: Conclusion: The two methods were both excellent internal fixations for thetreatment of unstable tibial fracture；For the patients with severe comminution, inparticular the patients need screw to reconstruc bone stability with multiple planar andmulti-angle, Steel combination lock auxiliary fixing screws was a better indication;For thetibia fractures, the fixation of intramedullary nail combined with screws was a betterindication.
