Abstract:
Objective:To compare the clinical effect of hollow screw tension band internal fixation and Kirschner wire tension band internal fixation for patellar fracture, so as to provide reference for clinical operation.Methods:A retrospective case-control study was conducted to analyze the clinical data of 82 patients with transverse patellar fracture admitted to the Department of Orthopedics of Linxi Hospital of Kailuan general hospital and the Department of orthopedics of Tangshan Central Hospital from May 2016 to October 2018.According to different operation methods, they were divided into Kirschner wire group (44 cases) and cannulated screw group (38 cases). The Kirschner wire group was treated with Kirschner wire tension band internal fixation, and the hollow screw group was treated with cannulated screw tension band internal fixation. The operation conditions, postoperative complications and postoperative knee function recovery of the two groups were compared.Results:The operation time of hollow screw group was significantly longer than that of Kirschner wire group((68.25±10.81) min vs.(59.72±12.32) min, t=3.31, P<0.05). Fracture healing time of hollow screw group was significantly shorter than that of Kirschner wire group((3.12±0.40) month vs.(3.68±0.45) month, t=5.91, P<0.05). B?stmanscores of the two groups increased significantly with time( Fintra-group=74.69, P<0.05). The B?stmanscore of cannulated screw group was significantly higher than that of Kirschner wire group ( Finteraction=4.87, P<0.05). The B?stmanscore of hollow screw group was significantly higher than that of Kirschner wire group( Finter-group=7.52, P<0.05). VAS scores in both decreased significantly with time( Finter-group=86.24, P<0.05). The decreasing of visual analogue scale (VAS) score in hollow screw group was significantly higher than that in Kirschner wire group( Finteraction=6.62, P<0.05). The VAS score in hollow screw group was significantly lower than that in Kirschner wire group ( Finter-group=7.74, P<0.05). The postoperative complications were 20.5% (9/44) in Kirschner wire group and 5.3% (2/38) in hollow screw group.The incidence of adverse reactions in hollow screw group was lower than that in Kirschner wire group (χ 2=4.05, P<0.05). The excellent and good rates of Kirschner wire group and cannulated screw group were 86.4% (38/44) and 94.7% (36/38), respectively, with no significant difference (χ 2=0.51, P>0.05). Conclusion:The results show that the two methods have the same effect on patella fracture, but the hollow screw tension band internal fixation has less trauma and less complications, which is conducive to the recovery of knee joint function.
