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.
The pisiform is a sesamoid bone, with no covering membrane of periosteum. It is the last carpal bone to ossify. 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
People with severe involvement often show lumps on the back of their finger joints (called "Garrod's pads", "knuckle pads", or "dorsal Dupuytren nodules"), and lumps in the arch of the feet (plantar fibromatosis or Ledderhose disease). [2] In severe cases, the area where the palm meets the wrist may develop lumps.
A bone tumor is an abnormal growth of tissue in bone, traditionally classified as noncancerous (benign) or cancerous (malignant). [1] [4] Cancerous bone tumors usually originate from a cancer in another part of the body such as from lung, breast, thyroid, kidney and prostate. [1] There may be a lump, pain, or neurological signs from pressure. [1]
They present as multiple small or large bumps characteristically on the heels and wrists. [2] Most are asymptomatic and pain is rare, although some may present with pain before the bumps are noticed. [3] They generally occur bilaterally and display a yellowish to skin-color. [3] They may feel soft or firm. [3] [4]
In cases of minor wrist pain, CTS, arthritis, injuries and sprains, it's often recommended that the patient wear a wrist brace throughout the healing process to provide extra support, pain relief ...
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 ...
