Is Bruising Typical After Carpal Tunnel Surgery?

Bruising is a common side effect of carpal tunnel release surgery. In very rare cases, it may be a sign of a complication that requires medical attention.

What causes bruising after carpal tunnel release?

During carpal tunnel release , a surgeon cuts through your transverse carpal ligament, relieving pressure on your median nerve. This procedure can cause an influx of blood and fluid into the area, leading to bruising and swelling along the pathway of the cut.

In a small 2014 study , about two-thirds of the participants experienced mild bruising 2 weeks after their surgery. In almost all cases, the bruising resolved after 6 weeks. Symptoms resolved quicker if the surgeon used dissolvable stitches .

How long does it take for bruising to go away after carpal tunnel surgery?

Bruising after carpal tunnel release may last a few weeks after your procedure. If bruising persists for longer or more severe symptoms occur, contact your doctor.

Is bruising after carpal tunnel surgery serious?

Bruising after carpal tunnel release usually isn’t a cause for concern. Major complications from this surgery are rare .

In rare cases, bruising may be a symptom of a hematoma, a collection of clotted blood that may occur as a complication of carpal tunnel release. In a 2018 study of 1,114 carpal tunnel surgeries, only 1 case of a hematoma emerged, and doctors identified it the day after the surgery.

Bruising that persists or develops later can sometimes be a sign that the surgery didn’t completely relieve compression on your median nerve. In these cases, doctors may recommend a second surgery.

How can I manage bruising after carpal tunnel surgery?

You can manage bruising and swelling at home after surgery. Consider the following:

• Apply a cold compress to your hand and wrist.
• Raise your hand above your heart to improve blood flow.
• Avoid heavy lifting.

Talk with a doctor if you have severe pain in your hand after carpal tunnel release or if bruising persists for longer than a few weeks.
