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.
