Thumb sprains, and other types of sprains, can range from a stretch or small tear in your ligament tissues to a complete tear through your ligament or a detachment from your bone.
What plane of motion is thumb abduction?
Abduction/adduction of the thumb occur within the sagittal plane and flexion/extension of the thumb occur within the frontal plane because the thumb rotated approximately 90 degrees evolutionarily. You can see this in anatomic position: the pad of fingers #2-5 face anteriorly, but the pad of the thumb faces medially.
What type of joint is the thumb MCP?
condyloid type synovial joints

What is the medical term for palmar plate?
Anatomical terminology. [edit on Wikidata] In the human hand, palmar or volar plates (also referred to as palmar or volar ligaments) are found in the metacarpophalangeal (MCP) and interphalangeal (IP) joints where they reinforce the joint capsules, enhance joint stability, and limit hyperextension.
Where is the volar plate located in the foot?
“Volar plate” redirects here. For the equivalent structures in the foot, see Plantar plate. In the human hand, palmar or volar plates (also referred to as palmar or volar ligaments) are found in the metacarpophalangeal (MCP) and interphalangeal (IP) joints, where they reinforce the joint capsules, enhance joint stability, and limit hyperextension.
