摘要

目的探讨基于结构光三维重建的成人第3指蹼间隙解剖形态学分型及其临床意义，为并指分离指蹼重建术提供数据支持。方法选取郑州大学科技园和郑州卫生健康职业学院志愿者126人为研究对象，年龄18~42岁，平均（25.07±4.62）岁，通过结构光三维扫描系统对第3指蹼间隙进行三维重建，基于三维模型测量近节指骨长度（proximal phalanx length，PPL）、指蹼实际长度（web length，WL）、掌骨间宽度（Intermetacarpal width，MD）、指蹼游离缘长度（free edge of web length，WW）等8项直接测量指标和4项间接指标。结果结构光三维重建第3指蹼间隙解剖学形态分为5种类型：陡坡型、微弧型、直线型、圆弧型、前凸型。圆弧型、前凸型的PPL3和PPL4小于微弧型，圆弧型和前凸型的PPL3小于陡坡型，前凸型的WH小于陡坡型，微弧型的WHR小于圆弧型和陡坡型，以上差异均具有统计学意义（P<0.05）。结论结构光三维重建第3指蹼间隙分为5种类型：陡坡型、微弧型、直线型、圆弧型、前凸型。不同的指蹼形态分型可为临床医生制定手术方式以及设计皮瓣形状提供解剖学依据。

Abstract

Objective To explore morphological classification and clinical significance of the third finger web based on 3D reconstruction of structured light scanner, so as to provide data support for the reconstruction of finger webbed separation. Methods A total of 126 volunteers from of Zhengzhou University Science Park and Zhengzhou Health Vocational College were selected as research objects, aged from 18 to 42 years old, with an average age of (25.07±4.62) years old. The 3D surface structured light scanner was used to measure the proximal phalangeal length (PPL), web length (WL), metacarpals distance (MD) and free edge of web length (WW), such as 8 direct measurement indicators and 4 indirect indicators. Results The anatomical morphology of the third finger web reconstructed by 3D structured light scanner can be divided into 5 types: steep slope-type, micro arcuate-type, straight line-type, circular arc-type, and convex-type. The PPL3 and PPL4 in convex-type were less than those in the micro arcuate-type. The PPL3 in circular arc-type and convex-type were less than those of steep slope-type (P<0.05). The WH in convex -type was smaller than that of steep slope-type (P<0.05). The WHR in micro arcuate-type was smaller than that of steep slope-type and circular arc-type (P<0.05). The differences were statistically significant. Conclusions The third finger web can be divided into 5 types: steep slope-type, micro arcuate-type, straight line-type, circular arc-type, and convex-type. Different morphological types of the third finger web can provide anatomical basis for clinicians to choose the operation methods and design of flap shape.
