Carpal tunnel biopsy


What is Carpal Tunnel Biopsy?

A Carpal tunnel biopsy is a medical procedure to remove a small sample of tissue from the carpal tunnel in the wrist. It is used to collect a sample for examination under a microscope in order to investigate and diagnose various diseases and conditions.

Why Carpal Tunnel Biopsy is Performed?

The procedure may be done to evaluate damage or other changes in the median nerve that runs through the carpal tunnel. Conditions that may cause changes and abnormalities in the median nerve that are evaluated with this procedure include:

  • Amyloidosis
  • Tumors
  • Diabetic peripheral neuropathy
  • Inflammatory reaction in the carpal tunnel

Preparation for Carpal Tunnel Biopsy

It is important to discuss your medical history and current condition with your surgeon before having a carpal tunnel biopsy. Your doctor may also ask you to stop taking certain medications for a period of time before the procedure.

Types of Carpal Tunnel Biopsy

There are two types of carpal tunnel biopsy: open carpal tunnel biopsy and endoscopic carpal tunnel biopsy.

  • Open Carpal Tunnel Biopsy – This involves making a small incision in the wrist region and taking tissue samples from the carpal tunnel.
  • Endoscopic Carpal Tunnel Biopsy – This involves using an endoscope, which is a thin, long tube with a tiny camera, to visualize and collect samples from the carpal tunnel. This type of biopsy is less invasive and can be done under local anesthesia.

Risks of Carpal Tunnel Biopsy

Carpal tunnel biopsy is a generally safe procedure, but it is important to be aware of potential risks and complications.

Risks include:
  • Infection
  • Excessive bleeding
  • Damage to the median nerve or surrounding tissues
  • Tingling or numbness in the hand or arm

Recovery After Carpal Tunnel Biopsy

After the procedure, your doctor will provide you with instructions on how to care for the wound and limit movement of the wrist and hand. It is important to follow these instructions to ensure a successful recovery. Depending on the type of biopsy done, you may need to limit physical activities and use a splint. You may also have to wear a sling or bandage for a few days. Your doctor may recommend physical therapy to ensure that you regain full use of your hand and wrist as quickly as possible.
