To investigate and illustrate a variation on the traditional percutaneous access to the vertebral body via a parapedicular approach.
An effective parapedicular access technique that could safely and reliably guide the needle tip into the center of the vertebral body was developed from cadaver dissection observations for the purpose of clinical use.
A total of 102 vertebral compression fractures from T-4 to L-5 were treated via the parapedicular access at our institution between July 2005 and March 2006. There were 72 patients between the ages of 17 and 96 years (mean age: 68.2 years) who underwent treatment.
The cadaver dissection revealed a relatively avascular and aneural portion of the vertebral body along the superior margin of the vertebral body-pedicle junction. A total 102 vertebral fractures were treated using the parapedicular access technique without any recognized clinical complications from the needle access or the instrumentation.
The thoracic and lumbar vertebral bodies may be safely, reliably, and reproducibly accessed using a percutaneous parapedicular access technique. The technique presented represents a relatively avascular and aneural approach to vertebral body.
研究并阐述一种经椎弓根旁入路的传统经皮椎体穿刺方法的变异。
基于尸体解剖观察，开发了一种有效的经椎弓根旁入路技术，旨在临床应用中能够安全可靠地将针尖引导至椎体中心。
2005年7月至2006年3月期间，在本机构通过经椎弓根旁入路治疗了102例T4至L5椎体压缩骨折。接受治疗的患者有72例，年龄在17至96岁之间（平均年龄：68.2岁）。
尸体解剖显示，沿椎体-椎弓根交界处上缘存在椎体相对无血管和无神经的区域。使用经椎弓根旁入路技术治疗了总共102例椎体骨折，穿刺或器械操作均未出现任何公认的临床并发症。
采用经皮经椎弓根旁入路技术可安全、可靠且可重复地进入胸腰椎椎体。所介绍的技术是一种相对无血管和无神经的椎体入路方法。
