There are many types of diseases or disorders that can affect the wrist and hand. These types of disorders and diseases affect the hand or wrist differently in each patient. The following list of conditions is described for educational purpose only and not to be used over the advice of your medical care provider.
Digital Tendon Entrapment
This is the condition is better known as trigger finger or trigger thumb. Digital tendon entrapment happens with daily use of the area, the tendon swells while causing friction to the tendon that causes even more swelling. This condition is diagnosed by placing pressure amount the edge of the palm; this may reveal a lump that moves with the tendon. When the tendon is in motion a clicking sound may be heard. Digital tendon entrapment is treated either with cortisone injections to help diminish the swelling or by surgically to help make room for the swollen tendon.
DeQuervain’s disease is diagnosed when the tendon sheath and tendons on the thumb side of the wrist become inflamed or swollen. The exact cause of DeQuervian’s disease is unknown, but it is thought to be the result of repetitive motion of the wrist and thumb. Symptoms of DeQuervain’s disease are pain and weakness along the forearm, thumb and wrist, swelling, a grating feeling in the wrist and increased pain when moving the area. DeQuervain’s disease is treated by splinting the area, stretching the tendons, rest, cortisone injections and possible surgery.
Dupuytren’s disease is the abnormal thickening of the tissue beneath the skin of the palm, often starting as firm lumps in the palm. On occasion, this disease many also cause thickening on the top of the knuckles. The signs and symptoms of Dupuytren’s disease are a lump in the palm of the hand, a fibrous band (cord) extending from the palm into a finger or fingers, this cord can cause the fingers to bend inward toward the palm. The bump and cord may eventually cause more bumps and cords among the fingers and palm. Dupuytren’s disease cause is unknown but may be because of biochemical factors with the tissue underneath the skin. Treatment includes various surgical techniques, but surgery will not be performed until the hand shows some type of deformity.
Kienbock’s disease is also commonly known as Avascular Necrosis of the Lunate. This condition is when one of the small bones of the wrist loses blood supply and dies off. When the small bone dies, it will cause pain and stiffness upon motion. Later stages of the disease cause what is known as bone collapses and shifts the other bones in the wrist, causing degenerative changes. The exact cause of Kienbock’s disease is unknown but may result from trauma. Treatment of Kienbock’s disease include providing a new blood supply or bone to the lunate, removing the lunate and bones to the side of the lunate, replacing the lunate or surgically fusing the wrist bones.
