English Abstract:

  【Abstract】 Objectives: To discuss the feasibility of percutaneous pedicle screw placement of lumbar spine in the field operation rescue shelter. Methods: Twelve pigs underwent percutaneous pedicle screw placement of lumbar in the field comprehensive operation rescue shelter. The weight of pigs, segments of operation, the number of screws, the operation time, blood loss, incision condition and postoperative lower limb activities were analyzed statistically. Results: Among 12 pigs in the group, the average weight was 26.32±3.45kg(21-30kg), L1-3 segments were for 8 pigs and L2-4 segments for 4 pigs, the average operation time was 80.45±2.45min(70-96min), the average blood loss was 5.73±0.37ml(2.5-7.7ml), the total of 72 pedicle screws were used. Among total 72 incisions, only 1 incision showed redness and swelling in 1 pig, but all pigs no incision infection occurred within 2 weeks follow-up, and the suture was removed 2 weeks after operation. All 12 pigs after anesthesia could walk normally without gait abnormal.　Conclusions: The percutaneous lumbar pedicle screw fixation has the advantage of less trauma, shorter operation time, less blood loss, which has certain feasibility in the field operation rescue shelter.
