Its mobility and stability differ significantly from those of the metacarpophalangeal joints of the long fingers. Stability predominates over mobility in this joint and is ensured by a complex interplay of capsuloligamentous, osteochondral, and both intrinsic and extrinsic musculotendinous structures. These components can be comprehensively evaluated using various imaging modalities. Soft tissues, including ligaments, tendons, aponeuroses, pulleys, and the volar plate, can be visualized particularly well using high-resolution ultrasound (US) and high-field magnetic resonance imaging (MRI).<\/jats:p>\n                  <jats:p>This educational review delineates the anatomy, physiology, and biomechanics of the thumb MCPJ, emphasizing the mechanisms underlying joint stability using high-resolution US and high-field MRI.<\/jats:p>\n                  <jats:p>A thorough understanding of the anatomy, physiology, and biomechanics of the thumb MCPJ is essential for accurate assessment of its pathologies. Such knowledge facilitates appropriate therapeutic decision-making and helps prevent significant functional impairment, in both the general population and among high-performance athletes.<\/jats:p>","DOI":"10.1055\/a-2834-3432","type":"journal-article","created":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T22:50:14Z","timestamp":1776207014000},"source":"Crossref","is-referenced-by-count":1,"title":["Thumb Metacarpophalangeal Joint.
