Attempts can be made to treat the deformity surgically by addressing the deforming bone and fibrous bands called "Vickers ligament". This is an abnormal ligament formed between the lunate bone of the wrist and the radius and is found in 91% of cases of Madelung's deformity.
The pisiform bone is a small bone found in the proximal row of the wrist . It is situated where the ulna joins the wrist, within the tendon of the flexor carpi ulnaris muscle. [1]: 199, 205 It only has one side that acts as a joint, articulating with the triquetral bone. It is on a plane anterior to the other carpal bones and is spheroidal in form.
It is also caused by fractures of the forearm bones if they cause bleeding from the major blood vessels of the forearm. [citation needed] The condition may be caused by obstruction on the brachial artery near the elbow, possibly from improper use of a tourniquet, improper use of a plaster cast, or compartment syndrome. [citation needed]
The bones closer to the forearm (proximal) are removed: scaphoid, lunate, and triquetrum. [14] It is important that the radioscaphocapitate ligament is left intact, because if the ligament is not preserved the capitate bone will translate to the ulnar side of the wrist and move away from the distal radius. [1] [15]
In this procedure, the radius (the lateral long bone) is shortened by a given length, usually between 2 and 5 mm, to relieve the pressure on the dying lunate. A titanium plate is inserted to hold the newly shortened bone together. [citation needed] During Stage 3, the lunate has begun to break apart due to the pressure of the surrounding bones.
Symptoms are pain and tenderness at the radial side of the wrist, fullness or thickening over the thumb side of the wrist, painful radial abduction of the thumb, and difficulty gripping with the affected side of the hand. [2] Pain is made worse by movement of the thumb and wrist, and may radiate to the thumb or the forearm. [2]
The triquetral bone (/ t r aɪ ˈ k w ɛ t r əl,-ˈ k w iː-/; also called triquetrum, pyramidal, three-faced, and formerly cuneiform bone) is located in the wrist on the medial side of the proximal row of the carpus between the lunate and pisiform bones. It is on the ulnar side of the hand, but does not directly articulate with the ulna ...
The capitate bone is a bone in the human wrist found in the center of the carpal bone region, located at the distal end of the radius and ulna bones. It articulates with the third metacarpal bone (the middle finger) and forms the third carpometacarpal joint. The capitate bone is the largest of the carpal bones in the human hand.
