"Minimally invasive surgery"steel plate for high energy fracture of tibial plateau

Objective:To explore the clinical effect of Minimally invasive surgerysteel plate in the treatment of high energy fracture of tibial plateau.Methods:A prospective study was conducted to analyze 27 cases of high energy fracture of tibial plateau who had been treated with internal fixation of Minimally invasive surgerysteel plate and LC-DCP.Their age was 21-59 years with an average of 36 years.Among them,male 19 and female 8;left 12 and right 15.According to classification of Schatzker:9 cases were type Ⅴ,18 cases were type Ⅵ.3 cases combined with avulsion of anterior cruciate lig(fixed with wire),2 cases combined with disruption of posterior cruciate lig(operation in the second period),3 cases had meniscus injury(2 were repaired,1 was cut partly).An anterior-lateral approach combined with a small posterior-medial approach was used to reduce the risk of soft tissue complication.The fractures were fixed with Minimally invasive surgerysteel plate and LC-DCP.All the patients were followed up in 2 weeks,1,3,6 months and 1 year after operation.Tibial plateau angle(TPA)and posterior slope angle(PA)of tibial plateau were measured to evaluate the stability of proximal tibia and knee alignment.The function of knee joint were evaluated according to criterion of HSS.Results:The mean value of tibial plateau angle(TPA)and tibial plateau posterior slope angle(PA)had no significant difference in one year after operation(TPA:t=1.012,P=0.356;PA:t=0.667,P=0.521).The mean HSS score was 86.9(56-98)points in one year after operation.According to criterion of HSS:15 cases obstained excellent results,7 good,4 fair and 1 poor.The total satisfactory rate was 81.5%.Conclusion:Minimally invasive surgerysteel plate is an effective method for high energy fracture of tibial plateau,which has the advantages of minimal trauma,less complication,high healing rate,reliable fixation and long-term stability.
