ObjectiveTo compare the efficacy between direct vision of the split bone block of the lateral condyle of the tibial plateau and tibial proximal feneway crowbar combined with MIPPO bone plate in the treatment of Schatzker type Ⅱ tibial plateau fractures.

MethodsTwenty-five patients with Schatzker type Ⅱ tibial plateau fractures were divided into the group A(13 cases) and group B(12 cases).The tibial plateau collapse in group A was reduced by direct vision of the split bone block of the lateral condyle of the tibial plateau, the group B was reduced by slotting tibial plateau and prying top bar, and two groups were additionally treated with MIPPO technique for anatomical plate internal fixation.

ResultsThere was no statistical significance in operative time and bleeding loss between two groups(P>0.05), and the length of incision in B group was significantly shorter than that in A group(P < 0.01).The starting time of knee joint exercise and bearing weight time in B group were significantly less than those in A group(P < 0.01), and there was no statistical significance in healing time of fracture between two groups(P>0.05).The differences of the varus angle and caster angle of tibial plateau between to groups at the end of operation, and postoperative 3, 6 and 12 months were not statistically significant(P>0.05).The excellent and good recovery rate of knee joint after operation in group A and group B were 84.61% and 90.67%, respectively, and the difference of which between two groups was not statistically significant(P>0.05).The difference of the HSS score of knee joint and incidence rate of complications between two groups was not statistically significant(P>0.05).

ConclusionsBoth kinds of articular surface of tibial plateau reset method can effectively restore the tibial plateau joint surface.The reduction of open window in proximal tibia is more minimally invasive, which can improve the recovery of patients.
