APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Saddle joints are also known as sellar joints, which are highly flexible joints.

Detailed explanation-2: -The wrist between the radius and carpals, and the knuckle between the metacarpals and phalanges contain ellipsoidal joints. Convex and concave areas form like a saddle to make saddle joints. Found in the thumb or first carpometacarpal joint, for example, these joints permit the same range of motion as condoloid joints.

Detailed explanation-3: -Hinge joints can be defined as the joints which work like door hinges, where only back and forth movement is possible. Example of hinge joints is the ankle, elbows, and knee joints. Saddle joint is the biaxial joint that allows the movement on two planes–flexion/extension and abduction/adduction.

Detailed explanation-4: -A saddle joint is a synovial joint where one of the bones forming the joint is shaped like a saddle with the other bone resting on it like a rider on a horse. Saddle joints provide stability to the bones while providing more flexibility than a hinge or gliding joint.
