What is Kienbock's disease blood supply?

Kienböck's disease is a condition where the blood supply to one of the small bones in the wrist, the lunate, is interrupted. The lunate is a carpal bone. Bone is living tissue that requires a regular supply of blood for nourishment. If the blood supply to a bone stops, the bone or parts of the bone can die.

What is the blood supply of the lunate bone?

The dorsal intercarpal and radiocarpal arches supply blood to the lunate from a plexus of vessels located directly over the lunate's dorsal pole. Vessels entered the dorsal aspect of the lunate through one to three foramina.

Does lunate have blood supply?

The blood supply of lunate comes along with various ligaments which may be disrupted due to trauma or strain leading to avascular necrosis. The present observations are suggestive of rich blood supply of lunate in comparison of other investigations.

What supplies blood to bone in wrist?

Therefore 2 different patterns of arterial supply can be described at the carpus: the blood supply of the outer and axial bones--scaphoid, trapezium, lunate, capitate--derives from the radial and the interosseous arteries and is probably shared equally by volar and dorsal branches; the inner bones--triquetrum, hamate-- ...

What is the pathophysiology of Kienbock's disease?

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate.

What happens if Kienbock's disease is left untreated?

The pain may vary in quality and duration and progressively worsen over time. Swelling and reduced grip strength may also occur. Most patients go untreated for months or years. If left untreated the lunate bone may fragment or collapse.

Is Kienbock's disease hereditary?

What is the problem with the lunate bone?
