Frequently Asked Questions

Find answers to our frequently asked questions

Patients can typically have Guyon’s canal decompression performed and go home the same day.

Patients have the procedure under local anaesthetic. 

An incision is made on the palm side of the wrist between the two fleshy mounds of the palm.

This allows for the nerve (ulnar nerve) that gives both sensations to the little and ring fingers and movement in the small muscles in the hand, free the tunnel & decrease pressure on the nerve.

The skin is closed with non-dissolving stitches and the hand dressed to protect the wound, but free enough to use when absolutely needed.

Patients who may have shooting pains, tingling or pins & needles into the little and ring fingers. 

This pain can feel like it is radiating towards the elbow and occasionally into the neck. 

This tends to worsen with direct pressure on the little finger side of the wrist, on the palm side such as from long rides on a bicycle.

When patients come into the clinic, our UK-trained plastic surgeon makes a full assessment of the patient.

This includes any relevant history, including reasons for surgery and a thorough examination including both hands for the feeling and muscle power.

Part of this process is explaining to the patients what can be done, why, and what to expect, based on each patients’ anatomy and suitability for surgery.

The swelling will have been removed as a result of surgery, so the area will be flatter than before.  

However, there will be a degree of swelling due to the operating and the local anaesthetic injection which will settle.

Immediately after surgery, each patient is seen by the senior physiotherapist who specialises in hand surgery patients, where they are given advice for what to look out for, what to expect and what can be done including exercise to help with rehabilitation. 

Patients can contact their team if they have any questions.

Patients are seen 10 days after surgery when the wounds are checked and stitches removed when the same physiotherapist will go through the exercises to help with rehabilitation after surgery.

For some patients, the problems may settle after rest. If this is not enough, patients may have used splints supplied by the GP or physiotherapists.

 They may have had anti-inflammatory medication such as Ibuprofen.
