What this Trial Is About
Carpal Tunnel Syndrome (CTS) is a common condition where pressure on the median nerve in the wrist causes pain, numbness, and weakness in the hand. Surgery to release the carpal tunnel is often performed to relieve these symptoms. This study will evaluate the changes in the median nerve after surgery and how these changes relate to symptom improvement. Investigators will use ultrasound imaging to measure the nerve size before and at three and six months after surgery. Patients will also complete questionnaires about their symptoms and hand function, and undergo tests to assess strength and sensation. The investigator's goal is to determine whether changes observed on ultrasound are associated with the rate of patient recovery. This may help doctors better monitor healing and improve care for people with CTS.
