Comparison and clinical application of two internal fixation methods for complex tibial plateau fractures
Objective To analyze and compare the stability and effect of two different internal fixation methods for complex tibial plateau fracture.Methods From January 2019 to January 2024,divided into group A and B according to the random table method,35 cases,group A using double plate technique,fixation for lateral locking plate+posterior medial 5 hole reconstruction plate fixation,group B for lateral locking plate+medial 3 hollow screw fixation.Surgery-related indicators(operation time,surgical bleeding,hospital stay,postoperative infection incidence),changes in knee function score(HSS),joint stability,and clinical effects of the two groups were compared.And analyze the vertical displacement and maximum failure load of the medial platform bone block under different loads.Results Group B had shorter operative time and hospital stay than group A,lower postoperative infection rate and intraoperative bleeding than group A(P＜0.05);there was no statistically significant difference in preoperative HSS scores between the two groups(P＞0.05);postoperative improvement was observed compared to preoperative levels,and the HSS score in group B was higher than that in group A(P＜0.05);the total effective rate of treatment in group B was 100%(35/35),which was higher than group A's 94.29%(33/35),but there was no statistically significant difference between the groups(P＞0.05).There was no significant difference in load-displacement and maximum failure load between the two groups(P＞0.05).Conclusion For complex tibial plateau fractures,the lateral locking plate has a positive effect,compared with the shorter course and lower infection rate than the posterior and medial 5-hole reconstruction plate,which is more conducive to promote the recovery of knee function.
