A bone on the ventral side of the shoulder girdle, which in humans is commonly called the collar bone.

The gliding joint formed by the outer extremity of the CLAVICLE and the inner margin of the acromion process of the SCAPULA.

A double gliding joint formed by the CLAVICLE, superior and lateral parts of the manubrium sterni at the clavicular notch, and the cartilage of the first rib.

Breaks in bones.

Inflammation of the bone.

Autosomal dominant syndrome in which there is delayed closing of the CRANIAL FONTANELLES; complete or partial absence of the collarbones (CLAVICLES); wide PUBIC SYMPHYSIS; short middle phalanges of the fifth fingers; and dental and vertebral anomalies.

The use of internal devices (metal plates, nails, rods, etc.) to hold the position of a fracture in proper alignment.

Implantable fracture fixation devices attached to bone fragments with screws to bridge the fracture gap and shield the fracture site from stress as bone heals. (UMDNS, 1999)

A fracture in which the bone is splintered or crushed. (Dorland, 27th ed)

A pathologic entity characterized by deossification of a weight-bearing long bone, followed by bending and pathologic fracture, with inability to form normal BONY CALLUS leading to existence of the "false joint" that gives the condition its name. (Dorland, 27th ed)

Union of the fragments of a fractured bone in a faulty or abnormal position. If two bones parallel to one another unite by osseous tissue, the result is a crossunion. (From Manual of Orthopaedic Terminology, 4th ed)

The physiological restoration of bone tissue and function after a fracture. It includes BONY CALLUS formation and normal replacement of bone tissue.

The upper or most anterior segment of the STERNUM which articulates with the CLAVICLE and first two pairs of RIBS.

Also called the shoulder blade, it is a flat triangular bone, a pair of which form the back part of the shoulder girdle.

Fractures in which the break in bone is not accompanied by an external wound.

"Dislocation is a traumatic injury wherein the normal articulation between two bones at a joint is disrupted, resulting in the complete separation of the bone ends and associated soft tissues from their usual position."

A fracture in which union fails to occur, the ends of the bone becoming rounded and eburnated, and a false joint occurs. (Stedman, 25th ed)

Part of the body in humans and primates where the arms connect to the trunk. The shoulder has five joints; ACROMIOCLAVICULAR joint, CORACOCLAVICULAR joint, GLENOHUMERAL joint, scapulathoracic joint, and STERNOCLAVICULAR joint.

Steel wires, often threaded through the skin, soft tissues, and bone, used to fix broken bones. Kirschner wires or apparatus also includes the application of traction to the healing bones through the wires.

Systematic physical exercise. This includes calisthenics, a system of light gymnastics for promoting strength and grace of carriage.

Mechanical or anoxic trauma incurred by the infant during labor or delivery.
