MRI Hand, Fingers & Thumb (Anatomy & Pathology) - Video Lesson

Hey, everyone. Welcome to today's lesson on the MRI of the hand, fingers, and thumb. In this lesson, we will look at bony structures of these parts, important ligaments and tendons, and anatomy on different planes of MRI imaging. Let's get started. The hand, finger, and thumb form a complex system of joints enabling precise movements. The hand is comprised of five metacarpals and fourteen phalanges. Each of these bones have specific parts of the base, shaft, and head. The base of each metacarpal and phalange are located proximal to the body with the head located distally. The carpometacarpal or CMC joints connect the carpals to the metacarpals with the thumb's CMC joint being a saddle joint while the finger CMC joints are gliding joints. The metacarpophalangeal or MCP joints of the fingers and thumb are condyloid permitting flexion extension abduction and adduction. The interphalangeal or IP joints, proximal and distal and fingers, single in
