文题释义:
经皮椎弓根手术:椎弓根螺钉技术由于其在脊柱三柱固定生物力学方面的优越性,使得其在脊柱外科手术中被广泛应用。但常规开放椎弓根手术需要对椎旁肌进行广泛的剥离和长时间的牵拉,这样往往导致椎旁肌肉的去神经和萎缩,引起脊柱融合病的发生。随着现代医学科学技术的进步,人们在力求椎弓根螺钉置入的安全和准确的同时,又探索运用微创的手段经皮置入椎弓根螺钉,从而有效的减少人为损伤。
椎弓根进针点定位:需清晰的脊柱X射线正侧位片和CT相应节段平扫。正位片了解椎弓根的位置,初步体表定位;侧位片了解椎弓根的矢状面倾角;CT平扫了解椎弓根成角及估计螺钉长度、直径。不同节段的椎弓根大小、形态、长度不一。
 
摘要
背景:微创经皮椎弓根螺钉内固定技术具有出血少、肌肉及软组织剥离少、术后恢复快等优点,而经皮椎弓根进针点定位是手术成功的关键。
目的:探讨自制网格定位板在经皮椎弓根微创手术进钉点定位中的应用价值。
方法:纳入2009年3月至2015年3月在南华大学附属第一医院接受胸腰椎段后路经皮椎弓根微创手术的患者428例,患者在经皮椎弓根微创手术前随机应用网格定位板或传统定位法(髂嵴定位、肋骨定位、伤椎形态定位、皮肤标志物定位、克氏针定位和穿刺针定位法)进行术前进针点定位,比较不同定位方法的定位准确率、定位时间及透视次数。

结果与结论:①网格定位板定位法定位准确率优于传统定位法(P < 0.05);定位时间短于传统定位法(P < 0.05);定位过程中透视次数少于传统定位法(P < 0.05)。网格定位板在脊柱经皮椎弓根微创手术中前定位的定位准确率、定位时间、透视次数均优于传统定位法;②结果表明,网格定位板法与传统定位法比较,具有定位准确率高、定位时间短、透视次数少等优点,在经皮椎弓根微创手术进针点定位中具有一定的优势。

Abstract:

BACKGROUND: Minimally invasive percutaneous pedicle screw fixation possesses the advantages of less blood loss, less muscle and soft tissue dissection, and rapid recovery; however, accuracy of the screw positioning is the key to be successful.

OBJECTIVE: To explore the application value of self-designed spinal localizer in the screw positioning for minimally invasive percutaneous pedicle screw fixation.
METHODS: 428 patients with thoracolumber disorders were subjected to minimally invasive percutaneous pedicle screw fixation at the First Affiliated Hospital of University of South China, from March 2009 to March 2015, and randomly underwent the preoperative screw positioning by self-designed spinal localizer or one of traditional localizing methods (iliac crest, ribs, symptomatic vertebral appearance, skin marker, Kirscher wire, puncture needle localizations). The location accuracy, positioning time and radiographic times were compared among methods.
RESULTS AND CONCLUSION: (1) Compared with the traditional localization methods, the self-designed spinal localizer was superior in accurate rate (P < 0.05), cost less positioning time (P < 0.05) and received less radiation (P < 0.05). (2) To conclude, the self-designed localizer exhibits a certain application value, which is an ideal method in preoperative localization for minimally invasive percutaneous pedicle screw fixation.
