Wrist Conditions and Injuries
Ganglion cysts are the most common mass or lump in the hand. They are common in the back of the hand. These fluid-filled cysts arise from the ligaments, joint linings or tendon sheaths when they are inflamed or irritated.
Common symptoms of carpal tunnel syndrome are numbness and tingling to the hand, especially at night; pain with prolonged gripping such as holding a steering wheel or clumsiness in handling objects. Sometimes the pain can go all the way up to the shoulder.
This is common in adult women between the ages of 30 and 50. It is an irritation and swelling of the tunnel which surround the thumb tendons as they pass from the wrist to the thumb. Pain when grasping or pinching and tenderness over the tunnel are the most common symptoms. If the hand is made into a fist with the thumb tucked in and bent towards the little finger, the pain gets worse.
The carpal boss is an osteoarthritic spur that develops at the base of the second and/or third carpometacarpal joints. (figure 1) A firm, bony, nonmobile, tender mass is visible and palpable at the base of the carpometacarpal joints, especially when the wrist is volar flexed.
The most commonly broken bone of the wrist is the radius. Many people think that a fracture is different from a break, but they are the same. When the wrist is broken, there is pain, swelling, and decreased use of the hand and wrist. Often the wrist appears crooked and deformed. Fractures of the small wrist bones, such as the scaphoid, are unlikely to appear deformed.
When someone falls on their outstretched hand, they sometimes get a "broken wrist." The bone that is usually broken is called the radius. It is the larger bone on the upper side of the photograph above. The end toward the wrist is called the distal end. The medical term for "broken bone" is fracture. Therefore, the medical term for the most common type of "broken wrist" is a distal radius fracture (that is, the larger forearm bone is broken near the wrist).
Fracture of the scaphoid bone occurs most frequently from a fall onto the outstretched hand. Typically there is pain initially, but the pain may decrease after days or weeks. Bruising is rare, and swelling may be minimal. Since there is no deformity, many people with this injury mistakenly assume that they have just sprained their wrist, leading to a delay in seeking evaluation. It is common for people who have fractured this bone to not become aware of it until months or years after the event.
