The base of the thumb, the first phalanx, makes a joint with a carpal bone called the trapezium, and the two articulate in a special joint called a saddle joint. You only have tow of these in your body, one at the base of each thumb.
The thumb is made up of two phalanges (one distal phalanx and one proximal phalanx), and one metacarpal. At the "visible base" of the thumb, or where the thumb seems to enter the hand, there is a condyloid synovial joint, which involves the articulation of the proximal phalanx on the first metacarpal. The TRUE base of the thumb is where the first metacarpal articulates with the trapezium (a carpal bone of the hand). This joint is a saddle-type synovial joint.
The area between the thumb and index finger (digitus secundus manus, pointer finger, or forefinger), is called the thenar space. The skin is called webbing. In other sources it is called thumb webbing. The muscles at the base of the thumb form the thenar eminence.
This could be a sign of thumb arthritis, also known as basal joint arthritis. It is a condition where the cartilage in the joint at the base of the thumb wears away, leading to pain, stiffness, and limited movement. It is important to consult a healthcare provider for proper diagnosis and treatment options.
A subluxed 1st carpometacarpal joint refers to a partial dislocation of the joint between the base of the thumb (1st metacarpal) and the carpal bone (trapezium). This can result in pain, limited mobility, and weakness in the thumb. Treatment may involve splinting, physical therapy, or in severe cases, surgery.
Yes, saddle joints are only found at the base of each thumb between the metacarpal head and the base of the second phalange bone. These joints are similar to elipsoid joints in that they allow for a back-and-forth and side-to-side movement; however, they also allow the thumb to be swiveled around so as to allow the pad of the thumb to touch the pads of all the other fingers. The corresponding joint in the big toe is an elipsoid joint, only. If it were a saddle joint, you would be able to oppose your big toe to the other toes -- just like the thumb in the hand!
The joint located at the base of the thumb is called the carpometacarpal joint.
The metacarpels are at the base of the thumb.
carpometacarpal joint
The thumb has two joints: the metacarpophalangeal (MP) joint at the base of the thumb and the interphalangeal (IP) joint at the tip of the thumb.
The thumb is made up of two phalanges (one distal phalanx and one proximal phalanx), and one metacarpal. At the "visible base" of the thumb, or where the thumb seems to enter the hand, there is a condyloid synovial joint, which involves the articulation of the proximal phalanx on the first metacarpal. The TRUE base of the thumb is where the first metacarpal articulates with the trapezium (a carpal bone of the hand). This joint is a saddle-type synovial joint.
yes there is a saddle joint at the base of the thumb.

Bunionectomy is surgical removal of a bunion, and abnormal enlargement of the joint at the base of the big toe.
It is known as the thumb basal joint, also known as the carpometacarpal joint. It is a special saddle-shaped joint that is formed by the small wrist bone and the first of the three bones in the thumb.
The area between the thumb and index finger (digitus secundus manus, pointer finger, or forefinger), is called the thenar space. The skin is called webbing. In other sources it is called thumb webbing. The muscles at the base of the thumb form the thenar eminence.
Fundus is the medical term meaning base.
