Abstract:
Objective
To compare the effect of hollow screw with that of pedicle hip locking compression plate in the treatment of displaced femoral neck fracture in children.
Methods
Twenty-four children with displaced femoral neck fracture treated in our hospital from September 2014 to October 2016 were selected as study group and they were divided randomly into observation group and control group, 12 cases in each group. Hollow screw internal fixation was performed in the observation group, and hip locking plate was used for internal fixation in control group. The results of fracture reduction, Ratliff evaluation, Harris score of hip joint, blood loss during operation, operation time and healing time were compared between the two groups.
Results
There was no significant difference between the two groups in the quality of fracture reduction, Ratliff evaluation or hip Harris score(P>0.05). The mean blood loss during operation was less in the observation group than that in the control group; the time of operation and the time of fracture healing were shorter than the control group, the difference being statistically significant(P<0.05).
Conclusion
Hollow screw and pediatric hip locking compression plate have similar effect in the treatment of displaced femoral neck fracture in children. However, the hollow screw has certain advantages in terms of blood loss, operation time and healing time.
