A ganglion cyst is a fluid-filled bump associated with a joint or tendon sheath. [3] It most often occurs at the back of the wrist, followed by the front of the wrist. [3] [4] The cause is unknown. [3] The underlying mechanism is believed to involve an outpouching of the synovial membrane. [4] Diagnosis is typically based on examination.
Carpometacarpal bossing (or metacarpal/carpal bossing) is a small, immovable mass of bone on the back of the wrist. The mass occurs in one of the joints between the carpus and metacarpus of the hand , called the carpometacarpal joints , where a small immovable protuberance [ 1 ] occurs when this joint becomes swollen or bossed.
Jaffé and Lichtenstein first coined the term "aneurismal cyst" in 1942 [11] In 1950 they modified this term to "aneurismal bone cyst". They may be associated with bone tumors. The simple bone cyst is a common, benign, fluid-containing lesion, most commonly found in the metaphysis of long bones, typically the proximal humerus or femur ...
Synovitis causes joint tenderness or pain, swelling and hard lumps, called nodules. When associated with rheumatoid arthritis, swelling is a better indicator than tenderness. The joints in your hands and fingers feel painful when pressed and when moving or gripping anything.
Magnetic resonance imaging (MRI) is the most accurate method for detecting bone masses in symptomatic cases to depict precise morphology of a tumor. It is used to verify if the palpable mass is continuous with the cortex of the affected bone and to differentiate an osteochondroma from other lesions on the surface of the bone.

The hand now has a deformed appearance. The only procedure that can be done is the total wrist fusion, where a plate is inserted on the top of the wrist from the radius to the carpals, effectively freezing all flexion and movement in the wrist. Rotation is still possible as it is controlled by the radius and ulna.
