Kienböck's disease is a disorder of the wrist.It is named for Dr. Robert Kienböck, a radiologist in Vienna, Austria who described osteomalacia of the lunate in 1910. [1]It is breakdown of the lunate bone, a carpal bone in the wrist that articulates with the radius in the forearm.
The cysts may intrude into the spine, which may cause pain and dysesthesia in distant extremities. [ 20 ] Cystic adventitial disease , in which a cyst occurs within the popliteal artery near the knee, has been proposed recently to occur by an articular mechanism, with a conduit leading from the joint, similar to the development of ganglion ...
Characteristic symptoms including pain, deformity and stiffness. Pain intensity and incapability (limited function) are notably variable and do not correspond with arthritis severity on radiographs. Osteoarthritis of the wrist can be idiopathic , but it is mostly seen as a post-traumatic condition.
An illustration of wrist pain. Wrist pain or open wrist is a syndrome inhibiting use of a hand due to pain in anatomical structures of the wrist. [1] It most commonly results from an injury to a ligament. [1] The pain may be sharp from a traumatic injury or from chronic repetitive wrist activities. [1]
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body.
The theory is that the radial nerve becomes irritated and/or inflamed from friction caused by compression by muscles in the forearm. [1]Some speculate that radial tunnel syndrome is a type of repetitive strain injury (RSI), but there is no detectable pathophysiology and even the existence of this disorder is questioned.

MRI provides better resolution of tissue density, absence of bone interference, multiplanar capabilities, and is noninvasive. Plain films may show bony erosion of the spinal canal or of the sacral foramina. [citation needed] On MRI pictures, the signal is the same as the CSF one. If MRI made with a contrast medium: [citation needed]
