Abstract

Abstract:

BACKGROUND: The surgeons are prone to leak a sacral fracture because of its junction with the spine and pelvis. Misdiagnosis and improper treatment of sacral fracture can cause further nerve injury and later lumbar sacral deformity, and its orthopedic operation is difficult and the curative effect is not as good as fresh fracture. Thereafter, early diagnosis and treatment of sacral fracture are very important.

OBJECTIVE: To carry out digital anatomic study of sacral part placement points using digital virtual technology, so as to provide guidance for clinical treatment.

METHODS: Sixty cases of adult pelvis CT scan (the ratio of men and women was 1:1) were selected randomly. The three-dimensional model was reconstructed by Mimics 16.0 software, and the measured points were selected. Then the related data were measured on the horizontal and sagittal planes, separately.

RESULTS AND CONCLUSION: (1) The midpoint of the interconnections between the lower edge of the L₅ and the upper margin of the posterior sacral hole of the S₁ was allowed. (2) The midpoint of the line between the lower margin of the sacral hole and the upper margin of the lower sacral posterior orifice, namely the pedicle point of the longitudinal multi scholar, allowed the nail to be placed equally. (3) The differences in the other measurements were insignificant (P > 0.05). (4) To conclude, the digital simulation technique is used to measure the nail point of the sacrum, and the depth and angle of the nailed points of each point can be used as a reference for the treatment of sacral fracture.
