It depends on the skill and experience of the surgeon. The joint is a unique one in that it is biaxial and called a saddle joint between the first metacarpal bone and one of the carpal bones called the trapezium.

What is the medical term meaning joint at the base of your thumb?
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.

What is type of joint found at the base 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.
What type of joint is found at the base of the thumb?
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.
Can you get gout in the base of the thumb?
Yes uric acid crystals can form in any skeletal joint
Is the thumb joint a hinge joint?
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!
What type of movement does the saddle joint allow?
The saddle joint is unique to humans and is located at the base of each thumb. It allows the thumb to touch the pinky finger by crossing over the palm of the hand. This allows humans to produce fine movements including sewing, writing, portrait painting, and anything other type of movement where the hand grasps a tool or the object itself as in pottery or peeling an orange.
Why is thumb wider and shorter than other thumb?
The thumb also has three joints, but the Proximal joint is farther up, embeded and mostly concealed in its muscles. That third [base joint] is what allows you to move the thumb to the left or right. NO. If you consider the thumb to have three joints you must be including the carpometacarpal joint which is (as far as i remember) a double saddle synnovial joint. This is the joint that joints the bone of the thumb that is concealed in the hand to the bones of the wrist. Within the visible thumb there is only two joints, the first being between the metacarpal and the proximal phalanx and the second being between the proximal and dislat phalanges. The other digits have and extra bone in the middle of these phalanges called the middle phalanx, giving it a third joint in the visible digit, or if you are including carpometacarpal joints as the original answer does with the thumb then you must do so for the fingers also which means they would have 4 joints each. And to answer the question the presence of a third joint in the thumb is simply unnecessary thanks the range of movement. The other digits require the extra joint so that the tips can come to meat close to the base of the visible digits so that before thumbs had evolvfed we could grasp small thin objects. The thumb has such a range of movement that this extra joint would be more effort to supply than its worth.
