摘　　要：目的比较自制复位装置与传统后路置钉短节段固定对胸腰椎骨折伤椎中央高度恢复效果。方法38例Magerl A3型胸腰椎骨折患者分别采用传统(n=23)或自制复位装置(n=15)后路经伤椎置钉及短节段内固定,比较两组术前、术后3 d及末次随访时伤椎中央高度压缩率并进行比较。结果38例患者平均随访13.0个月。术前、术后3 d及末次随访时,传统置钉组的伤椎中央高度压缩率分别为(69.3±9.3)%、(82.2±9.5)%及(80.6±9.3)%,复位装置组分别为(67.2±7.4)%、(88.6±7.9)%及(87.5±7.8)%。两组术后3 d及末次随访时伤椎中央高度压缩率均高于术前(P<0.01),末次随访与术后3 d比较差异无统计学意义(P>0.05)。复位装置组术后3 d及末次随访时伤椎中央高度压缩率均高于传统置钉组(P<0.05)。结论自制复位装置及传统置钉均能有效恢复伤椎中央高度,但复位装置辅助置钉的疗效优于传统置钉。Objective To compare the clinical efficacy of self-made reduction device(SMRD)-assisted and traditional posterior pedicle screw/short-segment fixation(PPS/SSF)in middle height of injured vertebral body(MHIVB)in thoracolumbar fracture(TLF).Methods Thirty-eight patients with Magerl A3 TLF underwent traditional(n=23)and SMRD-assisted(n=15)PPS/SSF.The compression ratios of MHIVB were compared between two groups before operation,at 3 days after operation and final follow-up.Results The mean follow-up of all patients was 13 months.The compression ratios of MHIVB were(69.3±9.3)%before operation,(82.2±9.5)%at 3 days postoperation and(80.6±9.3)%at final followup in traditional group;and(67.2±7.4)%,(88.6±7.9)%and(87.5±7.8)%in SMRD group.In both groups,there was significant difference between pre-and post-operation(P<0.01)but not between 3 days and final follow-up postoperation(P>0.05).The compression ratio was higher in SMRD group than in traditional group at 3 days and final follow-up after operation(P<0.05).Conclusion Both SMRD-assisted and traditional PPS/SSF are effective for restoring MHIVB,but SMRD obtains better efficacy.
