摘要: Objective: To investigate the effectiveness of percutaneous compression plate (PCCP) fixation for femoral neck fracture. Methods: A clinical data of 100 patients with femoral neck fractures who were treated with internal fixation were analyzed retrospectively. The fractures were fixed with the cannulated screws (CS) in 55 patients (CS group) and with the PCCP in 45 patients (PCCP group). There was no significant difference in gender, age, the cause of injury, the fracture type, complications, and disease duration between the two groups ( P>0.05). The quality of fracture reduction, bone resorption, screw slipping, femoral neck shortening, complications (nonunion, failure of fixation, and osteonecrosis of femoral head), and functional recovery of hip (Harris score) were compared between the two groups. Results: All incisions healed by first intention. All patients were followed up 24-56 months, with an average of 30.7 months. The quality of fracture reduction was excellent in 26 cases, good in 18 cases, fair in 9 cases, and poor in 2 cases in CS group and excellent in 21 cases, good in 17 cases, fair in 4 cases, and poor in 3 cases in PCCP group, showing no significant difference between the two groups ( Z=-0.283， P=0.773). The incidence of nonunion in PCCP group was significantly lower than that in CS group ( P=0.046), and the fracture healing time in PCCP group was shorter than that in CS group ( t=2.155, P=0.034). There was no significant difference in the incidences of bone resorption, screw slipping, femoral neck shortening, failure of fixation, and osteonecrosis of femoral head between the two groups ( P>0.05). The overall complication rates were 27.27% (15/55) in CS group and 8.89% (4/45) in PCCP group, showing significant difference ( χ2=5.435, P=0.020). The Harris score in PCCP group at 6 months after operation was significantly higher than that in CS group ( t=-2.073, P=0.041). However, there was no significant difference in the Harris score at 12, 18, and 24 months after operation between the two groups ( P>0.05). Conclusion: Stable sliding compression of PCCP is benefit for the femoral neck fracture healing, especially shortening union.
