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.

What is carpal instability?

Carpal instability occurs when the carpus is unable to maintain its normal alignment and motion under the influence of physiologic loads. Carpal instability must be differentiated from carpal misalignment.

What are the carpal bones?

The carpal bones are bones of the wrist that connect the distal aspects of the radial and ulnar bones of the forearm to the bases of the five metacarpal bones of the hand. There are eight carpal bones, which divide into two rows: a proximal row and a distal row.

What is Scapholunate dissociation?

Scapholunate dissociation is the abnormal orientation or movement of the small bones of your wrist: the scaphoid and lunate, in relation to one another.

How do you fix carpal instability?

Thin surgical instruments are inserted for surgery. An arthroscope may be used to reconstruct, trim, and repair torn ligaments. Surgery to repair carpal instability is usually followed by a period of immobilization with splinting or casting, followed by hand therapy rehabilitation.

How do you treat wrist instability?

Chronic scapholunate instability can be treated by ligament reconstruction and capsuloplasty or intercarpal arthrodesis. If the collapse deformity is reducible, ligament reconstruction and supplementation by a dorsal capsulodesis, as described by Blatt,13 may be considered (Fig. 10).

Is SLAC wrist painful?

Patients will likely present with some degree of pain although not all SLAC wrists are symptomatic. Pain is common and may be aggravated by heavy use and is sometimes associated with a clunking sensation during movement. [13] There will usually be a decreased wrist ROM and weakness of the grip strength.
