When the patient’s disorder in the hand is already heavily
damaged, there may be a need to undergo surgery. Carpal tunnel procedure is an operation that is
also known as “release.” The procedure can consist of two varieties, carpal tunnel open release and carpal tunnel endoscopic 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.
On the other hand, 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 generally
performed under local anesthesia. It is effective and can minimize scarring
and scar tenderness.
Over 200,000 cases of carpal tunnel surgery have been documented in the
United States, making it among the most common surgery of
the hand.
The decision whether to have either of the carpal tunnel
procedures to correct the syndrome may be puzzling a lot of patients. Electrodiagnostic tests for nerve conduction, ultrasound examination and
magnetic resonance imaging scans can be used to determine severity of the
condition. However,
there are no tests that can fully determine which patients will benefit most
from which of the carpal tunnel procedure.
Here are the findings of candidates that are less likely to respond to
non-surgical therapy and might end up benefiting more from the carpal tunnel
procedure:
* Older than 50 years.
* Symptoms have lasted 10 months or longer.
* Continual numbness.
* 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.
Not only those with carpal tunnel syndrome but also the general
public needs to know 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.
