Comparison of the effects of different fixation methods in the treatment of intercondylar comminuted fracture of the femur

Abstract

Objective To compare the effects of different fixation methods in the treatment of femoral intercondylar comminuted fracture. Methods From May 2015 to May 2017, 88 cases with femoral intercondylar comminuted fracture in Jiaxing Hospital of Zhejiang Armed Police Corps were selected in the research.According to the different fixation methods, the patients were divided into two groups.The control group(n=46) received dynamic condylar screw internal fixation treatment, the observation group(n=42) received the combination of fixed bridge treatment system.The related indicators of perioperative period, recovery of function after surgery, incidence of complications were compared between the two groups. Results The operation time, amount of bleeding, postoperative drainage, fracture healing time, postoperative weight-bearing time of the observation group were (104.36±20.72)min, (180.62±12.65)mL, (93.47±9.16)mL, (9.42±0.51)weeks, (4.62±1.81)weeks, respectively, which of the control group were (120.36±17.18)min, (269.74±20.24)mL, (62.31±7.34)mL, (10.32±0.67) weeks, (10.33±1.75)weeks, respectively, there were statistically significant differences between the two groups(t=3.96, 24.49, 17.50, 7.04, 15.04, all P<0.05). The joint function recovery rate of the observation group was 95.24%, which was higher than 76.09% of the control group(χ2=6.40, P<0.05). The incidence rate of complications in the observation group(4.76%) was lower than that in the control group(21.74%)(χ2=5.37, P<0.05). Conclusion The effect of bridged composite fixation system in the treatment of femoral intercondylar comminuted fracture is more effective than dynamic intercondylar screw fixation, and the clinical application value is higher than dynamic intercondylar screw fixation.
