Is it carpal tunnel? Here's how to know.
What is Carpal Tunnel Syndrome?
Carpal tunnel syndrome is a common condition of the hand caused by dysfunction of the median nerve as it enters the hand from the forearm. The nerve passes through a narrow space called the carpal tunnel on its way to the fingers and thumb.
The median nerve gives sensation to the thumb, index, middle, and half of the ring finger on the palm side. It also controls some of the small muscles in the hand. When it becomes compressed, the result is numbness, tingling, burning, pain, and weakness.
Anything that causes the contents of the tunnel to swell or the tunnel to get smaller can lead to carpal tunnel syndrome. This includes tendon swelling from repetitive strain, arthritis, diabetes, and obesity.

How is carpal tunnel syndrome diagnosed?
Any patient experiencing symptoms more than once or twice a week should be assessed by a qualified healthcare provider. A physician, physiotherapist, or nurse practitioner can perform an initial assessment.
Diagnosis typically involves a combination of physical examination, medical history, nerve conduction studies, and ultrasound. Ultrasound can show more detailed nerve anatomy and swelling, and is increasingly used alongside nerve conduction testing. Many conditions can mimic CTS, so a proper diagnosis is important before proceeding to treatment.

From symptoms to surgery: your pathway to relief.
Non-Surgical Options

Steroid injections
Surgical Options
Open Release:
Incision: 3 to 4 cm palm incision
Sutures: 3 to 5 required
Anesthetic: Local only
Endoscopic Release
(Dr. Loiselle's technique):
Incision: ~1 cm wrist incision
Sutures: 1 dissolving suture
Anesthetic: Local only
Why Endoscopic:
- Less pain — Smaller incision means less post-operative discomfort.
- Faster return to activity — No palm incision means quicker return to work and sport.
- Minimal scarring — Very small scar, difficult to see after 6 months.
