Annular ligament of radius

The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna.

Ball and socket joint

The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone.

Capitulum of the humerus

In human anatomy of the arm, the lateral portion of the distal articular surface of the humerus consists of a smooth, rounded eminence, named the capitulum of the humerus.

Joint

A joint or articulation (or articular surface) is the connection made between bones in the body which link the skeletal system into a functional whole.

Projectional radiography

Projectional radiography is a form of radiography and medical imaging that produces two-dimensional images by x-ray radiation.

Pulled elbow

A pulled elbow, also known as a radial head subluxation, is when the ligament that wraps around the radial head slips off.

Radial notch

The radial notch of the ulna (lesser sigmoid cavity) is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius.

Radius (bone)

The radius or radial bone is one of the two large bones of the forearm, the other being the ulna.

Subluxation

In medicine, a subluxation is an incomplete or partial dislocation of a joint or organ.

Synovial joint

A synovial joint, also known as diarthrosis, joins bones with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces.

Tendon

A tendon or sinew is a tough band of fibrous connective tissue that usually connects muscle to bone and is capable of withstanding tension.

Ulna

The ulna is a long bone found in the forearm that stretches from the elbow to the smallest finger, and when in anatomical position, is found on the medial side of the forearm.

Ulnar collateral ligament of elbow joint

The ulnar collateral ligament (UCL or internal lateral ligament) is a thick triangular band at the medial aspect of the elbow uniting the distal aspect of the humerus to the proximal aspect of the ulna.
