概述

一、疾病概述或定义骨关节炎是临床上最常见的一种慢性关节炎,随着年龄的增长患病率逐渐增加。OA影响了全球24 000万人的生活,严重威胁着人类的健康。据世界卫生组织统计,在全球60岁以上的老年人中,约9.6%的男性和18%的女性患OA,在发达国家中,25%的OA患者伴有残疾。0A主要表现为关节疼痛、功能障碍,严重者可致畸。 二、病因及发病机制软骨细胞是关节软骨中唯一的细胞,关节软骨的稳定依赖于软骨细胞,而软骨细胞又可以维持细胞外基质的平衡,因此,损害软骨细胞的功能和存活将会导致关节软骨的

The thumb carpometacarpal (CMC) joint is a biconcave saddle joint between the thumb metacarpal and trapezium that allows for multiplanar movement. High compressive forces through the CMC joint, up to 120 kg with power grasp and 12 kg with tip pinch, may predispose this joint to degenerative arthritis. Arthritis of this joint more commonly occurs in women than in men, starting in middle adulthood and increasing in prevalence with age; radiographic prevalence ranging from 33% of postmenopausal women to as high as 100% of women older than 91 years is described. The anterior oblique ligament incompetence has been shown to play a role in the progression of CMC arthritis.In 1967, Richard Eaton and William Littler developed a ligament reconstruction procedure for refractory thumb CMC arthritis that reinforced the joint capsule in two planes. They subsequently described four progressive radiographic stages of CMC arthritis in 1973, which later was modified to include scaphotrapezial arthritis. This modified Eaton-Littler classification is now the most commonly used radiographic classification system for basilar thumb arthrosis.

拇指腕掌(CMC)关节是拇指掌骨和梯形之间的双凹面鞍关节,允许多平面运动。通过CMC关节的高压缩力,功率掌握高达120 kg,尖端捏12 kg,可能使这种关节易于退行性关节炎。这种关节的关节炎更常见于女性,而不是男性,从成年中期开始,随着年龄的增长而增加;描述了放射学患病率从绝经后妇女的33%到高于91岁的女性的100%。前斜肌韧带功能不全已被证明在CMC关节炎的进展中起作用。1967年,理查德·伊顿(Richard Eaton)和威廉·利特勒(William Littler)开发了韧带重建术,用于治疗难治性拇指CMC关节炎,在两个平面上加强关节囊。他们随后在1973年描述了CMC关节炎的四个渐进性放射照相阶段,后来被修改为包括肩胛关节炎。这种改进的Eaton-Littler分类现在是最常用的基底拇指关节病的放射学分类系统。
