  【摘要】 目的：探讨在野战方舱内施行腰椎经皮椎弓根螺钉内固定术的可行性。方法：选取12只实验猪，于方舱内施行腰椎经皮椎弓根螺钉内固定术，统计分析实验猪的体重、手术节段、置钉数量、手术时间、术中失血量、术后切口愈合情况及术后肢体活动情况。结果：本组12只实验猪体重为21～30kg，平均26.32±3.45kg；手术节段L1～Ｌ3节段8只，L2～Ｌ4节段4只，手术时间70～96min，平均80.45±2.45min，失血量2.5～7.7ml，平均5.73±0.37ml。本研究共置入72枚椎弓根螺钉，均成功置钉；共72个切口，术后2周时随访发现仅有1只实验猪的切口出现红肿，均未见切口感染发生，均术后2周拆除缝线。所有12只动物麻醉苏醒后均可正常行走，且步态未见异常。结论：腰椎经皮椎弓根螺钉内固定术具有创伤小、手术时间短、失血少的特点，在野战方舱内施行该手术具有可行性。

  【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.
