Facet Joint Surface Models

This Item includes 2,900 files with the individual facet joint surfaces from 29 lumbar spines from L1 to S1 levels. Each specimen has four files per level: the superior and inferior surfaces for each side of the joint. UPDATE Version 2: The files for 1312011 FLEX position have been corrected. In Version 1 those were incorrect files.Additionally, these surfaces were captured at one of five spine positions: neutral, flexion, extension, right lateral bending, right axial rotation.Nomenclature: [Specimen number][spinal Level][side][location][position] Example: "1405044L2RSNEU.txt" is the Right Superior L2 facet surface of specimen 1405044 in neutral position.Specimen number is a 7 number string ex. 1405044Spinal Level: L1 to L5 in addition to S1 (Sacrum)Side is Left or Right (L or R)Location is Inferior (I) or Superior (S)Position is one of five: neutral (NEU), flexion (FLEX), extension (EXT), right lateral bending (RLB), and right axial rotation (RAR).

本数据集包含来自29个腰椎（L1至S1水平）的关节面独立切片的2,900个文件。每个样本在每个水平上均包含四个文件：每侧的关节上下表面。更新版本2：1312011 FLEX位置的文件已更正。在版本1中，这些文件是错误的。此外，这些表面是在五个脊柱位置之一捕获的：中立、屈曲、伸展、右侧侧弯和右侧轴向旋转。命名法：[样本编号][脊柱水平][侧面][位置][姿势] 示例：“1405044L2RSNEU.txt”是样本1405044在中立姿势下的右侧L2关节面。样本编号为一个7位数字字符串，例如1405044。脊柱水平：L1至L5，以及S1（骶骨）。侧面为左侧或右侧（L或R）。位置为五种姿势之一：中立（NEU）、屈曲（FLEX）、伸展（EXT）、右侧侧弯（RLB）和右侧轴向旋转（RAR）。
