Mechanical Analysis of Posterior Pedicle Screw System Placement and Internal Fixation in the Treatment of Lumbar Fractures

Table 1

Characteristics of pedicle internal fixation system.

Characteristics of pedicle internal fixation system
Feature 1	Early reduction and internal fixation, fixed tightly
Feature 2	Short-segment fixation
Feature 3	Restore the normal physiological radian of the spine
Feature 4	Restore the cross-sectional area of the spinal canal, rebuild the stability of the spine, achieve effective and complete decompression, and relieve the strain on the spinal nerves. Promote the recovery of nerve function
Feature 5	Full bone graft fusion, high fusion rate of bone graft
Feature 6	Patients can get out of bed early
