Carpal Tunnel Complications

In persistent or severe cases of carpal tunnel syndrome, surgery may be required to relieve the often times debilitating symptoms. The most common type of surgery procedure for the relief carpal tunnel symptoms is called "carpal tunnel release". There a various techniques that can be used when performing this type of surgery, however, in all of these procedures the "transverse carpal ligament" which is pressing on the nerve is cut in order to relieve the pressure.

These surgeries are typically done on an out-patient basis using a local anesthetic and no hospital stay is required. The majority of individuals who have this surgery experience complete relief from carpal tunnel symptoms or a significant decrease in pain and numbness, however, this type of invasive procedure does not come without risks and a small number of individuals have experienced minor to severe complications. 

The Potential Minor Complications when Having Carpal Tunnel Release 

While it is rare that complications will arise from having carpal tunnel surgery, there are risks involved just as with all other types of surgery performed. Although it is quite rare, problems can occur with the anesthesia that is used - especially if it interacts with other types of medication.

Infection can occur around the incision that is made during the surgery. Fever, swelling, redness, heat coming from the incision area, and pain which is not relived by medication are all signs of an infection. There is also the potential for excessive scar tissue to form which is caused by the attempt of the body to heal itself and sometimes over compensates with too many new cells. When this happens, tightness may be felt in the skin and the area surrounding the incision may be raised or a lump may be felt underneath the incision. 

This scar tissue formation can also cause restricted movement and there is the potential for this scar tissue to bind and affect the median nerve and tendons which can cause complications with movement inside the carpal tunnel and a decrease in the range in which you can move your hand.

In cases where this scar tissue is excessive, corrective surgery may be needed to remove this extra tissue. Some individuals may also experience nausea and vomiting as well as swelling around the incision which is persistent. 

Rare Complications due to Carpal Tunnel Surgery

In some instances, there are severe complications which can occur when having "carpal tunnel release" surgery. The chances of severe complications arising also depend greatly on the individuals overall health and any other medical related conditions.

Some of the rare complications directly related to the carpal tunnel surgery include damage to major nerves within the hand. These nerves include the median nerve itself and the ulnar nerve. In the rare instances when the median nerve is accidently cut or damaged, a loss of feeling will occur in the thumb and palm of the hand. 

In some cases the release of the carpal ligament is not successful and this is called "incomplete release of the carpal ligament". When this situation occurs, the patient may still experience significant symptoms of carpal tunnel, and in some cases a second surgery may be required.

Another severe complication that can occur accidently is damage to the artery which runs through the palm of your hand. While complications from carpal tunnel surgery are rare, individuals who are considering this type of surgery should consult with their doctor to completely understand any risks involved.
