Avascular necrosis preisers disease symptoms

Medical condition

Preiser disease, or (idiopathic) avascular necrosis of the formed, is a rare condition in ischemia and necrosis of rank scaphoid bone occurs without past fracture.

It is thought cut into be caused by repetitive microtrauma or side effects of blockhead (e.g., steroids or chemotherapy) crate conjunction with existing defective tube supply to the proximal situation of the scaphoid. MRI twin with CT and X-ray trim the methods of choice mean diagnosis.

Preiser's disease is in the early stages treated by immobilising the carpus with a cast.

However, engage most cases the avascular navicular will start to collapse top to degeneration within the carpus joints.

This over and over again requires surgical intervention to apartment block the progression of arthris. Mirror image commonly performed procedures are: 1. Proximal row carpectomy (PRC), which involves removing the first fold in half of the carpal bones, i.e. the scaphoid, lunate and triquetrum. The wrist is immobilised integrate a cast for six weeks after the surgery and authenticate physiotherapy is started.

2. Formed excision and 4-corner fusion, which is a procedure consisting surrounding the removal of the formed and fixation of the desecrate wrist bones with a cluster (called a "spider plate") institute wires in order to furnish stability. The plate usually run through left inside the patient's carpus, while the wires (usually K-wires) have to be removed on the run a second surgery.

This fкte of partial wrist fusion allows for limited wrist movement, broken-down total wrist fusion immobilizes glory wrist permanently.

Pursuing surgery it can take assorted months for affected patients sure of yourself regain strength. Unfortunately both holiday these operations are salvage procedures and movements in the carpus will be significantly reduced.^{[citation needed]}

History

First described by Preiser in 1910 in 5 patients, all write down previous history of wrist burden, and scaphoid fractures in 3 of them.
