The distal radioulnar articulation [1] (also known as the distal radioulnar joint, [2] or inferior radioulnar joint [1] [3]) is a synovial pivot joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal radioulnar articulation.
DRUJ stress test: With this provocation maneuver, the wrist is held in pronated or supinated position, while the physician attempts to manipulate the distal ulna in dorsal and volar direction. Painful laxity indicates DRUJ instability and suggests RUL pathology. [2] Ulnar grind test: The forearm is fixated and the wrist is held in dorsiflexion.
Distal radius fracture; Other names: Broken wrist [1] A Colles fracture as seen on X-ray: It is a type of distal radius fracture. Specialty: Orthopedics, emergency medicine: Symptoms: Pain, bruising, and swelling of the wrist [1] Usual onset: Sudden [1] Types: Colles' fracture, Smith's fracture, Barton's fracture, Hutchinson fracture [2] Causes ...
Finkelstein's test was described by Harry Finkelstein (1865–1939), an American surgeon, in 1930. [5]A similar test was previously described by Eichhoff, in which the thumb is placed in the palm of the hand and held with the fingers, and the hand is then ulnar deviated (see images), causing intense pain over the radial styloid which disappears if the thumb is released.
Joints of the hand, X-ray. The bones in each carpal row interlock with each other and each row can therefore be considered a single joint. In the proximal row a limited degree of mobility is possible, but the bones of the distal row are connected to each other and to the metacarpal bones by strong ligaments that make this row and the metacarpus a functional entity.
Total wrist arthrodesis is the standard surgical treatment for patients with stage IV wrist osteoarthritis. During this procedure the carpal bones are all fused together and are then fastened to the distal radius. [14] This procedure eliminates all wrist motion, but heavy labor is still possible. [19]
The procedure consists of making a hockey-stick shaped incision along the ulnar border. This incision is made between the fifth and sixth dorsal compartment. Being careful not to harm any essential structures, like the posterior interosseous nerve , the incision is continued between the extensor carpi ulnaris and the extensor digiti quinti ...
The interosseous membrane is composed of 5 ligaments:- Central band (key portion to be reconstructed in case of injury)- Accessory band- Distal oblique bundle- Proximal oblique cord- Dorsal oblique accessory cord. Severe forearm injuries involving separation of the radius and ulna may be due to rupture of the interosseous membrane.
