What is gilula arc?

What is gilula arc?

Gilula’s carpal arcs are used to determine carpal alignment. They can assist in identifying ligamentous injury, dislocations and fractures of the carpus on X-ray. They are of used in the sometimes difficult to interpret x-rays of the carpal bones.

Which is a carpal bone?

Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.

What do carpals do?

The carpal bones allow the wrist to move and rotate vertically.

At what age do the carpal bones ossify?

The main finding in this study is that carpal bones start to ossify in the first year of life, starting approximately at the age of 6 months. This ossification of carpal bones starts with the capitate and hamate.

What attaches to scaphoid?

The palmar surface of the scaphoid is concave, and forming a tubercle, giving attachment to the transverse carpal ligament. The lateral surface is narrow and gives attachment to the radial collateral ligament.

Are Carpals irregular bones?

Irregular bones: Irregular bones are irregular in size and shape and are usually quite compact. They include the bones in the vertebral column, the carpal bones in the hands, tarsal bones in the feet, and the patella (kneecap).

Are Carpals short bones?

Short Bones Are Cube-shaped The carpals in the wrist (scaphoid, lunate, triquetral, hamate, pisiform, capitate, trapezoid, and trapezium) and the tarsals in the ankles (calcaneus, talus, navicular, cuboid, lateral cuneiform, intermediate cuneiform, and medial cuneiform) are examples of short bones.

What are Gilula’s three carpal arcs?

Gilula three carpal arcs refer to the carpal alignment described on posteroanterior or anteroposterior wrist radiographs and are used to assess normal alignment of the carpus: The concept of three radiographic arcs was first proposed by Louis A Gilula (1942-2014) in 1979 3,5 .

What are Gilula’s lines used for?

Gilula’s lines. Gilula carpal arcs. Gilula’s lines are three arcs drawn on an AP radiograph of the wrist used to assess the alignment of the carpal bones.

What does a disrupted arc indicate?

disrupted arc may indicate a ligamentous injury or fracture at the site of the broken arc
