3d Medical Image Reconstruction of Modified Closed Reduction and Three Hollow Nail for The Treatment of Gardon Iv Femoral Neck Fracture

Objective: To explore the clinical effect of improved closed reduction assisted by 3D medical image reconstruction compared with traditional closed reduction combined with three cannulated nails in the treatment of Gardon IV femoral neck fracture. Methods: By analyzing the follow-up data of 63 patients received by us from 2010 to 2016 (all of whom had the above two treatments), the corresponding conclusions were drawn. The results showed that 24 of 63 patients were treated with modified closed reduction combined with three hollow nail internal fixation technology (experimental group). 3D medical image reconstruction improved closed reset simulation and demonstration based on the fracture end before surgery. There are 39 cases were treated by traditional closed reduction combined with three hollow screws internal fixation (control group). All patients were followed up for more than 1 year. To compare the operation time, bleeding volume, healing time, reduction quality (Garden index grading after operation), quality of life (hip function recovery) of patients with Gardon IV femoral neck fracture treated by two closed reduction methods combined with three hollow nail internal fixation technology, and Harris evaluation at the last follow-up. Differences in incidence of postoperative complications. Results: The operation time and intra-operative bleeding volume of the experimental group were (66.42± 23.85) min and (50.00 ± 35.75) ml, respectively, which were significantly less than those of the control group (87.49 ±29.98) min and (74.62 ± 35.53) ml. It has posses statistical significance (t ₁ = 2.919, P ₁ < 0.01; t ₂ = 2.661, P ₂ < 0.01). The healing time of the experimental group was (3.20 ± 0.29) months, slightly shorter than that of the control group (3.40 ±0.31) months, with statistical significance (t ₃ = 2.524, P ₃ < 0.05). The Harris score of the last follow-up group (88.10 ± 4.88) was significantly higher than that of the control group (83.16 ± 4.08), with statistical significance (t ₄ = 5.016, P ₄ < 0.01). The quality of fracture reduction in the experimental group was significantly different from that in the control group (Z = 2.118, P ₅ < 0.05). Complications occurred in 1 case (1/24) in the experimental group, which were less than 4 cases (4/39) in the control group. Conclusion: Compared with the traditional closed reduction, 3D animated modified closed reduction combined with three hollow nail for the treatment of Gardon IV femoral neck fracture has a small trauma, a significant effect of closed reduction, high recovery of hip function, clinical efficacy and postoperative. The advantages of less complications, such as Gardon IV femoral neck fracture have a good therapeutic effect.
