A Clinical Comparative Study Of Sustaining Plate And Locking Plate To Treat In Tibial Plateau Fractures

Objective:To contrast and analyse the clinical therapeutic effect of the sustaining plate(SP), locking plate (LP) to treat the tibial plateau fractures.Methods:From March2010to May2012, we chose44patients andomly with fracture of the tibial plateau who had been operated in the third xiangya hospital of central south university, including19cases of SP,25cases of LP and then contrasted and analyzed two groups of the patient’s age, gender, injury, fracture parting ratio, operation time, amount of bleeding in operation, volume of blood transfusion, length of hospital stay, healing time of fracture, evaluation results of knee function. After a week,1month or3months, patients were reviewed by X-ray; then depending on the situation of fracture healing, every four to six weeks of X-ray were reviewed on the patients who were not recovery, and followed10-18months, an average of14months, we recorded fracture healing time, contrasted and analyzed of fracture healing and knee function, according to the HSS curative standard. All the data were analyzed by SPSS19.0。Results:1. When contrasted with gender structure, averaged age, the combined hurt, fracture parting ratio, there were no statistically significant differences between the two groups (p>0.05), and the conditiong of the patinents was the same which suggest that it had comparability.2. Volume of bleeding in operation in SP group is330.53±146.191ml, LP group is222.63±107.437ml, there were significant differences between the two groups (p<0.05), the SP group’s volume of bleeding in operation was more than the LP group.3.Two groups of patients who underwent postoperative hospitalization time, volume of blood transfusion, were not statistically significant (p>0.05).4. In the LP group the operation time was104.74±21.697min,the SP group was142.37±24.173min, there were significant differences between the two groups (p<0.05),the operation time of SP group is longer than the LP group.5. In LP group fracture healing time was23.32±4.69weeks, and the SP was27.68±6.33weeks, statistically significant (p<0.05), the healing time of SP group fracture was longer than the LP group. And type Ⅰ、Ⅱ、Ⅲ、Ⅳ fracture is primary healing, the two groups’excellent and good are100%; however, in type Ⅴ、Ⅵ fracture,1patient’s healing time was delayed in locking plate group, and2in SP group.6. When compared the patients’knee function evaluation, the SP group’excellent and good was78.94%, and the locking plate group was92.00%, there was statistically significant between the two groups(p<0.05). and knee function of patients were not excellent and good in type Ⅴ、Ⅵ fracture. After surgery, in the evaluation of knee function, the SP group is worse than LP group in type Ⅴ、Ⅵ fracture.Conclusion:LP is better than SP in volume of bleeding in operation, the operation time, healing time of fracture and the evaluation of knee function.
