The wrist is an area much like the shoulder, where a variety of movement is necessary in normal use. Rotation of the joint as well as lateral movement can cause an extra amount of stress not only to the muscles and tendons that make up the structure of the joint, but also to the nerves and blood vessels that serve the structure. Damage to the wrist area from repetitious movement, trauma or even infection and old age may contribute to extensive pressure on the blood vessels, sometimes leading to thrombosis (blood clotting).
The arteries that service the wrist can endure significant stress over time, especially when repeated motion exerts pressure in the area. Constriction of blood flow over time may cause damage to these arteries, causing the blood flow to be curtailed enough to result in blockage, which may result in clotting. This is generally considered to be rare by some medical professionals, yet the occurrence of blood clots in the wrist may necessitate the use of MRI or ultrasound examination to identify the problem.
According to The Hand University, the ulnar and median nerves that service the wrist and hand structure pass through what is known as Guyon’s canal. This canal is a tube-like tunnel that runs through the wrist, through which the nerves as well as the arteries enter the wrist area. Damage from repeated movement, known as Guyon’s canal syndrome, or from trauma to the area can contribute to clotting in the blood as it passes through. While this is also considered to be a rare condition, it may nonetheless occur.
The symptoms of blood clots in the wrist can be similar to symptoms of nerve damage in this area. Generally speaking, a feeling of numbness or tingling may be felt in the wrist or possibly in the hand and fingers. According to the Colorado Hand and Arm P.C., these sensations may also be accompanied by pain or stiffness in the area of the wrist and the hand. The effect is the same on both the nerves and the arteries that service these areas, in that a trauma or other force has caused a stoppage of flow either of nerve signals or, in the case of arteries, of blood.
Swelling and discoloration can also be signs of blood clotting. This may not be easily diagnosed as thrombosis, due to the tendency of extremities, such as the arm, to swell naturally from either resting in its natural status (hanging by the side of the body) or from collection of blood in the wrist and hand area when sleeping. Discoloration will likely be in the form of bruising in the wrist area. This will be a more positive indication of a possible blood clot problem, especially in cases where no reported force trauma or injury has occurred.
The range of possibilities for development of blood clots in the wrist area may necessarily suggest a thorough examination by a doctor or other medical professional who is experienced in thrombosis diagnostics when related symptoms occur. While occurrences of blood clotting in the wrist are infrequent, the condition can and will develop in some cases.
