Carpal Tunnel Procedure
When the patient’s disorder in the hand is already heavily damaged, there is a need to undergo surgery. Carpal tunnel procedure is a major operation that is known as “release.” Procedure is of two kinds namely,
- Carpal tunnel open release
- Carpal tunnel endoscopic release
Carpal Tunnel Open Release
Carpal tunnel open release is the traditional procedure used to correct carpal tunnel syndrome. It consists of making an incision up to two inches in the wrist and then cutting the carpal ligament to enlarge the carpal tunnel. This type of carpal tunnel procedure is generally done under local anesthesia on an outpatient basis, unless there are unusual medical considerations.
Carpal Tunnel Endoscopic Release
On the otherhand, carpal tunnel endoscopic release may allow faster functional recovery and less postoperative discomfort. The surgeon makes two incisions (about ½" each) in the wrist and palm, inserts a camera attached to a tube, observes the tissue on a screen and cuts the carpal ligament.
This kind of carpal tunnel procedure is two-portal where it is generally performed under local anesthesia. It is effective and minimizes scarring even scar tenderness, if there is any. Over 200, 000 cases in the United States have been documented going through carpal tunnel procedure; thus, making it among the most common surgery of the hand.
Until now, the decision whether to have either of the carpal tunnel procedures to correct the syndrome has been puzzling a lot of patients. Electrodiagnostic tests for nerve conduction, ultrasound examination and magnetic resonance imaging scans are used to find out severity.
However, there are no tests that can fully determine which patients will advantage most from which of the carpal tunnel procedure.
People Who Are Less Likely To Respond To Conservative Therapy
Here are the findings of candidates that are less likely to respond to conservative therapy and might end up benefiting more from the carpal tunnel procedure:
- Older than 50 years.
- Continual numbness.
- Symptoms have lasted 10 months or longer.
- The muscles in the base of the palm have begun to atrophy (shrink).
- Symptoms occur within 30 seconds during a Phalen's test.
A study conducted in 2002 revealed that if one of those factors mentioned above are present, then conservative therapy, such as wearing wrist splints and taking anti- inflammatory agents, are effective in about two- thirds of the candidates. It was also found that the traditional approach was not proven efficient in some of 60 patients if only one of those said factors were present.
Not only those with carpal tunnel syndrome need to know but also the general public that carpal tunnel procedure does not totally cure the syndrome. There is the notion that because the carpal ligament is permanently cut, some wrist strength is lost. A lot of orthopedic specialists suggest aggressive conventional treatment before choosing the more invasive option.
