Where is the wrist joint located?
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.
What bones are part of the radiocarpal joint?
The radiocarpal joint is a synovial joint formed by the articulation between the distal radius and the scaphoid, lunate, and triquetrum as well as the soft tissue structures that hold the joint together.
How many Radiocarpal joints are there?
Many wrist injuries (such as fractures, also known as a broken bone) involve the joint surface. There are three joints in the wrist: Radiocarpal joint: This joint is where the radius, one of the forearm bones, joins with the first row of wrist bones (scaphoid, lunate, and triquetrum).
What other name refers to radiocarpal joint?
The radiocarpal joint is sometimes referred to as the wrist joint. But it's actually one of two joints in the wrist, the other being the midcarpal joint. The radiocarpal joint is where the radius bone of the forearm meets the first row of carpal bones in the lower hand.

Osteoarthritis (OA) of the wrist vs carpal tunnel syndrome. Wrist Osteoarthritis causes localised pain, stiffness and swelling around the wrist joint. The pain is located at the wrist crease and is often tender to touch.
Can you Circumduct your wrist?
Circumduction is the movement of the limb, hand, or fingers in a circular pattern, using the sequential combination of flexion, adduction, extension, and abduction motions. Adduction, abduction, and circumduction take place at the shoulder, hip, wrist, metacarpophalangeal, and metatarsophalangeal joints.
Is radiocarpal joint a hinge joint?
Pivot and hinge joints are functionally classified as uniaxial joints. Condyloid joints are found where the shallow depression of one bone receives a rounded bony area formed by one or two bones. Condyloid joints are found at the base of the fingers (metacarpophalangeal joints) and at the wrist (radiocarpal joint).
What is palmar radiocarpal ligament?
The palmar radiocarpal ligament (Volar Radiocarpal Ligament, anterior ligament) , is a broad membranous band, attached above to the anterior margin of the lower end of the radius, to its styloid process, and to the front of the lower end of the ulna; its fibers pass downward and medialward to be inserted into the volar ...
What is the back of the wrist called?
The human hand consists of a broad palm, the metacarpus, with 5 digits attached to the forearm by a joint called the wrist, or carpus. The back of the hand is formally called the dorsum of the hand.

Carpal bones in the wrist
Your wrist is made up of eight small bones called the carpal bones, or the carpus. These join your hand to the two long bones in your forearm — the radius and ulna. The carpal bones are small square, oval, and triangular bones.
Is the wrist joint a hinge joint?
(2) Hinge joints move on just one axis. These joints allow for flexion and extension. Major hinge joints include the elbow and finger joints. ... The wrist joint between the radius and the carpal bones is an example of a condyloid joint.
Which bones form wrist joint?
The wrist is a complex joint that bridges the hand to the forearm. It is actually a collection of multiple bones and joints. The bones comprising the wrist include the distal ends of the radius and ulna, 8 carpal bones, and the proximal portions of the 5 metacarpal bones (see the images below).
What bones articulate the wrist joint?
The wrist joint generally refers to the radiocarpal joint, which is the articulation between the distal end of the radius and the articulating surface of the scaphoid, lunate, and triquetral bones. Other articulations in the wrist area include the distal radius and ulnar and the carpal bones.
What is a hinge joint?
A hinge joint is a type of synovial joint that exists in the body and serves to allow motion primarily in one plane. ... [3][4] The hinge joints of the body include the elbow, knee, interphalangeal (IP) joints of the hand and foot and the tibiotalar joint of the ankle.
What are examples of hinge joints?
Hinge Joint Examples
A hinge joint is a type of joint that can only be bent in the plane of motion. Finger joints, the elbow and knees are examples of this type of joint. However, the elbow is a complex joint that involves two different joints, a hinge joint and a swivel joint.
What is a saddle joint?
Saddle joints are a type of synovial joint that allow articulation by reciprocal reception. Both bones have concave-convex articular surfaces which interlock like two saddles opposed to one another.
What is adduction?
Adduction: Movement of a limb toward the midline of the body. The opposite of adduction is abduction.
What is carpal tunneling?
Carpal tunnel syndrome (CTS) occurs when the median nerve, which runs from the forearm into the palm of the hand, becomes pressed or squeezed at the wrist. The carpal tunnel—a narrow, rigid passageway of ligament and bones at the base of the hand—houses the median nerve and the tendons that bend the fingers.
What is an example of hyperextension?
A hyperextension injury occurs when a joint is moved past its normal angle of extension. For example, this may happen to the elbow during sports, often when "punching air" or practicing one's swing in tennis. The injury known as "tennis elbow" is, in fact, a form of hyperextension injury.
What is Kienbock's disease?
Kienböck's Disease. Kienböck's disease is a condition where the blood supply to one of the small bones in the wrist, the lunate, is interrupted. Bone is living tissue that requires a regular supply of blood for nourishment. If the blood supply to a bone stops, the bone can die.
Why does the top middle of my wrist hurt?
One of the most common types of pain in the wrist is carpal tunnel syndrome. This is a type of inflammation that puts pressure on the nerves running through the carpal tunnel in your wrists.
What is Radiocarpal arthritis?
Radiocarpal arthritis occurs where the small bones and the long forearm bones meet. Sometimes both areas can be involved. Distal radioulnar arthritis occurs where the radius meets the ulna at the wrist. This causes pain with turning the hand palm up or palm down.
