摘要

目的探讨腰椎椎间孔成形靶区的三维形态学特征及其临床意义，为脊柱内镜下经椎间孔入路腰椎间盘切除术中精准椎间孔成形提供解剖学依据。方法选取122例腰椎上关节突，采用高精度三维扫描技术重建椎间孔成形靶区，测量椎间孔成形靶区线性参数：AB（上关节突腹侧至椎体后缘距离）、CD（上关节突基底部至上终板距离）、EF（椎弓根宽度）、 R1（AB/CD比值）。基于形态特征对椎间孔成形靶区进行解剖学分型，测量靶区三维体积及关节面面积。结果椎间孔成形靶区分为3种形态：Ⅰ型（类梯形，50%）、Ⅱ型（窄柱形，32%）、Ⅲ型（丘陵形，18%）。Ⅰ型AB最长、R1值居中、体积最大；Ⅱ型AB最短、EF最宽、R1值最低；Ⅲ型CD最短、关节面面积最小、R1值最高。各分型间参数差异显著（P<0.05）。结论腰椎椎间孔成形靶区形态可分为3种，以Ⅰ型为主，多维度参数可量化靶区空间特征与生物力学潜力，对精准椎间孔成形具有一定的临床参考意义。

Abstract

Objective To investigate the three-dimensional morphological classification of lumbar foraminoplasty target area and their clinical significance, providing an anatomical basis for precise foraminoplasty in transforaminal endoscopic lumbar discectomy. Methods A total of 122 lumbar superior articular processes were selected, and foraminoplasty target area was reconstructed using high-precision three-dimensional scanning technology. Linear parameters of the target area were measured: AB (distance from the ventral side of the superior articular process to the posterior edge of the vertebral body), CD (distance from the base of the superior articular process to the superior endplate), EF (pedicle width), and R1 (AB/CD ratio). Anatomical classification of foraminoplasty target area was performed based on morphological characteristics, and the three-dimensional volume and articular surface area of the target area were measured. Results Foraminoplasty target area was divided into three morphological types: Type I (trapezoid-like type, 50%), Type II (narrow-columnar type, 32%), and Type III (hilly-shaped type, 18%). Type I had the longest AB, moderate R1 ratio, and largest volume. Type II had the shortest AB, widest EF, and lowest R1 ratio. Type III had the shortest CD, smallest articular surface area, and highest R1 ratio. Significant differences in parameters were observed among three types (P<0.05). Conclusions The morphology of target area for lumbar transforaminal foraminoplasty can be divided into three types, with type I being the most common. Multi-dimensional parameters can quantify the spatial characteristics and biomechanical potential of target area, which has certain clinical reference significance for precise transforaminal foraminoplasty.
