Application of robot positioning in cannulated screw internal fixation for the treatment of femoral neck fracture: a retrospective study
ABSTRACT
Background:
Femoral neck fractures are a common type of hip fractures. Conventional surgical treatment aims at fixation of the fracture site with screws, and then gradually promote bone healing. The orthopedic surgery robot-assisted system is a computer technology applied to surgical treatment.
Objective:
To explore the therapeutic effect and prognostic value of percutaneous cannulated screw internal fixation using robot-assisted positioning in patients with femoral neck fractures.
Methods:
Forty-two cases with femoral neck fractures, admitted to the Second Affiliated Hospital of Luohe Medical College from July 2018 to September 2019 were randomly divided into a control group and a study group, 21 cases in each group. The patients in control group were treated with conventional percutaneous cannulated screw internal fixation, and the patients in study group were treated with robot-assisted percutaneous cannulated screw fixation in the surgical treatment. The treatment conditions and results of the operation in the two groups of patients were compared. Harris score was used to evaluate the treatment efficacy. Follow-up observation of fracture healing of two groups of patients was carried out.
Results:
The duration of the operation, the frequency of fluoroscopy use, and the number of drilled holes in study group were less than those in control (P < .001). There was no statistical difference in the amount of intraoperative bleeding between the two groups (P = .33). The Harris score and the excellent and good rate of study group was significantly higher than that of the control (P = .045). The difference of fracture healing rate between study group and control group was not statistically significant (P = .23). The fracture healing duration of the study group was shorter than that of the control group (P = .001).
Conclusions:
The use of robotic positioning aids in the treatment of femoral neck fractures with percutaneous cannulated screw fixation can effectively improve the efficiency of surgery, shorten the duration of surgery, and reduce the radiation damage to patients. Meanwhile, it improves postoperative treatment and recovery rates of the patients and shortens the fracture healing time.
