经椎旁肌间隙入路微创小切口在胸腰段骨折术后内固定取出术中的应用

目的观察经椎旁肌间隙入路微创小切口在胸腰段骨折术后内固定取出术中的应用。方法 40例腰段骨折术后患者行内固定取出,随机分为传统组和小切口组,每组20例。传统组经原手术切口取出内固定;小切口组在C臂X线机下定位或体表触摸定位取出。观察两组的手术时间、手术切口长度,记录术中出血量、术后体温及术后24 h疼痛视觉模拟评分（VAS）。结果传统组：手术时间（64.6±13.1）min,手术切口（14.0±3.1）cm,术中出血量（310±160）ml,术后体温（38.6±1.2）℃,24 h VAS评分（8.4±0.5）分,住院时间（7.1±0.5）d。小切口组：手术时间（40.2±10.2）min,手术切口（4.1±0.7）cm,术中出血量（68±15）ml,术后体温（37.3±1.1）℃,24 h VAS评分（5.2±0.6）分,住院时间（3.0±0.2）d。两组手术效果各项比较差异均有统计学意义（P〈0.01）。结论与传统内固定取出术比较,经椎旁肌间隙入路微创小切口取出内固定有减少手术时间、术中出血量、术后发热及疼痛程度等优点。

The clinical effect of trans-paraspinal muscles minimally invasive approach in the fixation removal of thoracolumbar fractures

Objective To study the clinical values of trans-paraspinal muscles minimally invasive approach in the fixation removal of thoracolumbar fractures.Methods 40 patients required postoperative lumbar fractures internal fixation removal were randomly divided into two groups,traditional groups and trans-paraspinal muscles group,20 patients in each group.The traditional incision group were removed by the original approach.Trans-paraspinal muscles group in space X-ray C-arm positioning or surface under the touch lo...
