Clinical Analysis Of The Treatment Of Liss-df And CBP In The Type C Distal Femur Fracture

Objective: To compare the effects of the treatment of LISS-DF and CBP in type C distal femur fracture.Methods: From January 2002 to December 2009, 139 patients of type C distal femur fracture were treated. 63 cases with LISS-DF: type C1 for 24 cases, type C2 for 20 cases, type C3 for 19 cases; 76 cases with CBP: type C1 for 30 cases, type C2 for 26 cases, type C3 for 20 cases, The operation time, intraoperative bleeding, fracture heeling time, the function recover of knees in both treating methods were recorded and analysed.Results: 139 cases were follow up from 1 to 4 years, with an average of 1.8 years. The function of the knees were evaluated with the HHS.①Operation time in the LISS—DF group was 40～150min with an average of 80.49±24.54min;and CBP group was 50～160min with an average of 108.34±27.67min.The difference between two groups was statistical significance(P<0.05).②The intraoperative bleeding in the LISS-DF group was 130～500ml with an average of 287.57士95.66ml; and the CBP group was 190～700ml with an average of 380.45士80.92ml. The difference between two groups was statistical significance(P<0.05).③The fracture heeling time in the LISS-DF group was 2～6 monthes with an average of 3.58士0.88monthes; and the CBP group was 3～7monthes with an average of 4.46士0.97monthes. The difference between two groups was statistical significance(P<0.05).④The HHS on the function of knee joint in two operative methods exhibited no obvious difference (P>0.05).Conclusions: Both the LISS—DF and the CBP had good clinic curative effects in treatment of the type C distal femur fracture. LISS-DF compared with CBP has advantages on the reduction of operation time, bleeding volume, surgical trauma, fracture heeling time.
