Anatomical study of the radial side of thumb metacarpophalangeal joint: the joint capsule and flexor pollicis brevis muscle
The flexor pollicis brevis muscle contributes to dynamic stabilization of the thumb metacarpophalangeal joint via its aponeurosis, which integrates with the joint capsule and radial collateral ligament. These findings provide new insight into metacarpophalangeal joint stability and may improve surgical and rehabilitative approaches for radial-sided thumb instability.
