单侧肋椎关节入路椎体成形术的临床解剖研究

Clinical anatomy of unilateral rib vertebral joint approach vertebroplasty

目的：研究经单侧肋椎关节穿刺行椎体成形的影像学特点，探讨在影像学监测下经肋椎关节穿刺的安全操作范围。方法：12具成人防腐完整（ T5～T12）脊柱标本，测量椎体矢状面、水平面标准位像前1／3中心点与肋椎关节上缘夹角。结果：下胸椎行椎体成形术，经肋椎关节穿刺时，T5～T12上倾角为19°~24°，外倾角先减小后逐渐增大，为27°~36°之间，T5最大，T9最小；外倾角的安全范围为22°~49°，左右两侧对比无显著差异，男女对比无显著差异。结论：行椎体成形术时，中下胸椎经单侧肋椎关节进针是安全可行的。

Objective：To research by unilateral rib vertebral joint puncture of imaging features vertebroplasty,discuss in radiological monitoring by Sternocostal joint puncture safe operating range.Methods：12 adult preservative complete （ T5-T12 ） spinal specimens, Measuring vertebral sagittal, standard bit like one-third of the former center of the horizontal angle between the joint Sternocostal .Re-sults：Under the thoracic vertebroplasty, when rib vertebral joints by puncture,T5-T12 inclination on for 19 °-24 °, camber increases after the first decrease, Between 27 °-36 °, T5 maximum, T9 minimum;The camber angle of the safe range 22 °-49 °, left and right sides was no significant difference in comparison, contrast was no significant difference between men and women.Conclusion：When ver-tebroplasty, lower thoracic vertebral joints by unilateral rib needle might be safe and feasible.
