OBJECTIVE: To investigate the preliminary clinical effect of closed reduction and cannulated nail internal fixation for femoral neck fracture assisted by robot navigation and positioning system.
METHODS: From July 2019 to January 2020, 16 cases of femoral neck fracture (navigation group) were treated with closed reduction and internal fixation guided by robot system, including 7 males and 9 females, aged 25 to 72 years old with an average of (53.61±5.45) years old;Garden classification of fracture:3 cases of typeⅠ, 3 cases of typeⅡ, 8 cases of type Ⅲ, 2 cases of type Ⅳ. Non navigation group (control group):20 cases of femoral neck fracture were treated with closed reduction and hollow nail internal fixation, 8 males and 12 females, aged 46 to 70 years old with an average of (55.23±4.64) years old;Garden typeⅠin 2 cases, typeⅡin 4 cases, type Ⅲ in 11 cases, type Ⅳ in 3 cases. The operation time, fluoroscopy times, guide needle drilling times, screw adjustment times, intraoperative bleeding volume and other indicators of two groups were evaluated.
RESULTS: Both groups were followed up for 12 to 18 months with an average of (15.6±2.8) months. The fractures of both groups were healed without delayed union and nonunion. There was no significant difference in healing time between two groups( P =0.782). There was no significant difference in Harris scores between two groups at the last follow-up( P =0.813). There was no significant difference in operation time between two groups( P >0.05). There were significant differences between two groups in fluoroscopy times, guide needle drilling times, hollow screw replacement times, and intraoperative bleeding volume( P <0.05).
CONCLUSION: Closed reduction and hollow screw internal fixation assisted by robot navigation system for femoral neck fracture has the advantages of minimally invasive operation, precise screw placement, and reduction of X-ray radiation damage during operation.
