They often are not diagnosed initially and present delayed as lunate osteonecrosis, which is also known as Kienbock disease. Changes for Fat Loss by with a free trial. Towson, MD 21204 J Hand Surg Am. (SBQ07SM.38) In this condition, the lunate bone loses its blood supply, leading to death of the bone. Treatment requires urgent closed versus open reduction and stabilization. The most important differential is of other carpal dislocations, particularly: In addition to stating that a lunate dislocation is present, a number of features should be sought and commented upon: ensure that radiolunate alignment is disrupted, and that you are not looking at a perilunate dislocation(stage II carpal dislocation), evaluate and comment on the degree or palmar rotation of the lunate (this can be up to 270 degrees)4, ensure that the capitate remains co-linear with the long axis of the radius, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Most likely, the most reliable test to assess the blood supply of the lunate is Magnetic Resonance Imaging (MRI). Distal radius fractures are themost common orthopaedic injury and generally result from fall on an outstretched hand.

The plate may need to removed once the fracture is healed to reduce the chance of flexor pollicis longus injury, The plate may need to removed once the fracture is healed to reduce the chance of flexor carpi radialis injury, The plate may need to removed once the fracture is healed to reduce the chance of flexor digitorum superficialis index finger injury, The patient should undergo revision fixation as soon as possible, The plate is in appropriate position and will likely never need to be removed.
