Carpal Tunnel Syndrome (CTS)
The carpal tunnel is a narrow space inside the wrist that allows certain tendons and a major nerve (median) to pass from the forearm into the hand. Carpal Tunnel Syndrome (CTS) is caused when there is a narrowing of the carpal tunnel. This problem is caused by a compression of the median nerve resulting from a thickening or enlarging of the tendon sheath. CTS is a problem that affects the wrist and hand. Tingling and numbness are the most common symptoms. Some people experience hand pain and a weakened grip.
Depending upon severity, CTS can be treated with medications, injections, splinting, or surgery. Your physician will assist you in determining the most appropriate options. He or she will peform a comprehensive examination and may run other diagnostic tests such as X-ray, MRI, Nerve Conduction Study, or EMG.
Trigger Finger (tenosynovitis) is an inflammation of tissue inside your finger or thumb. The symptoms include pain in the base of your finger or thumb where they join the palm. You may also experience swelling. As the tendon becomes more inflamed, them the finger may catch when you are trying to straighten it. When the tendon releases, then the finger jumps, similar to releasing the trigger of a gun. This releasing action further irritates the tendon and may start a cycle of catching and swelling.
Trigger Finger can be treated with oral anti-inflammatories or injections. If conservative measures are not effective, then your physician may recommend surgery. During the procedure, the sheath surrounding the tendon is opened to enlarge the space and release the swollen tendon, allowing the finger to bend and straighten normally.
