What are the movements of the wrist joint?

The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand. A condyloid joint is a modified ball and socket joint that allows for flexion, extension, abduction, and adduction movements.

What movements occur at the radiocarpal joint?

The radiocarpal joint allows proper hand movements, this includes flexion, extension, adduction, and abduction of the wrist but the supination and pronation of the hand, movements known as rotation, cannot be done by the hand as a unit or independent in relation to the forearm.

What movement does a saddle joint allow?

Saddle joints allow movement with two degrees of freedom much like condyloid joints. They allow flexion / extension, abduction / adduction and therefore also allow circumduction. Unlike ball and socket joints, saddle joints do not allow axial rotation.

What type of joint is a wrist joint?

synovial joint
The wrist is an ellipsoidal (condyloid) type synovial joint, allowing for movement along two axes. This means that flexion, extension, adduction and abduction can all occur at the wrist joint.

What is the neutral position of the wrist?

The neutral position of the wrist is that position where the wrist is in straight alignment with the forearm: no flexion, extension, radial or ulnar deviation. The wrist is at the mid-point between supination and pronation. This is commonly called the handshake position.

Which is not a movement that occurs at the wrist?

Pronation and supination are movements of superior and inferior radio-ulnar joints. Wrist joint has nothing to do with these movements. In pronation, the opposite happens with tightening of dorsal ulna-carpal soft tissues and ECU lies ulnar to Ulna rather than on dorsal aspect.

What is a Condyloid Joint example?

The condyloid joint occurs where an egg-shaped surface of a bone fits into a concavity in another bone. Examples include the wrist joint (radiocarpal joint) and the temporomandibular joint.

What is a saddle joint example?

The prime example of a saddle joint is the trapeziometacarpal joint at the base of your thumb. It connects the trapezium and the metacarpal bone of your thumb. This is also a fairly common site for osteoarthritis, which can cause pain, weakness, and stiffness in your thumb and inner wrist.

What is the difference between a condyloid joint and a saddle joint?

Condyloid joints are found at the base of the fingers (metacarpophalangeal joints) and at the wrist (radiocarpal joint). At a saddle joint, the articulating bones fit together like a rider and a saddle. Plane joints are formed between the small, flattened surfaces of adjacent bones.

Which joint is unique to the hand and how does this joint move the hand?

Which joint is unique to the hand, and how does this joint move the hand? Condylar & Saddle joint; the are biaxial and moves the hand in two planes.

Which of the following is the neutral position for the hand and wrist?

Neutral wrist position is the most protective. This is the position when your hand is in line with your wrist. A flexed position is palm down, with the palm and fingers bent towards the inner wrist. An extended position is with the palm up.
