Nerves are responsible for delivering your feeling and function in your arm and hand. There are three principle nerves that reach your hand, but important branches of these nerves supply other structures in your upper limb. Each major nerve passes through anatomically tight points on its journey to your hand. At these points, the nerves are prone to entrapment. If a nerve gets squashed or tethered, it’s normal function becomes interrupted. Normally this is initially intermittent and the nerve recovers, but eventually, the nerve can develop scarring and never function fully again.
There a three main nerve compression syndromes that may require surgery. Each will be covered:
This is very common and patients often have bilateral symptoms. Your median nerve runs along the centre of your forearm as it passes across your wrist into your hand. Here it shares a tunnel with your finger flexor tendons. Any cause of swelling in the tunnel can compress your nerve. Symptoms typically include:
- Pins and needles in your thumb, index and middle finger
- Symptoms often worse and wake you at night
- Aching in your forearm
- Loss of fine touch sensation in the tips of your thumb, index and middle fingers
- Weakness of grip and certain thumb movements
Your symptoms and clinical examination are often highly suggestive. Nerve testing (neurophysiology) can clarify the extent of nerve dysfunction, but is sometimes normal even in the presence of convincing symptoms. This is done with you awake, takes 30 minutes and is mildly uncomfortable only
If your symptoms are mild and your nerve function good, you may be successfully treated with a splint and an injection (cortisone). If your symptoms are more intrusive, or they fail to respond to an injection and splinting, you may require surgical release of your carpal tunnel
This is a day-case operation performed with you wide awake under local anaesthetic. You are given a numbing injection (this stings for about 10 seconds like a dental injection) . Your hand is then cleaned and draped. A tourniquet on your upper arm may be used to minimise bleeding in the surgical field - this is normally only inflated for about 5 minutes and often does not need to be elevated at all. After checking your surgical area is numb a 3cm incision is made over the front of your wrist. The tight ligament that is trapping your median nerve is released fully to ensure there is ample ‘breathing room’ for your nerve. Your nerve is inspected to ensure it is free (you are welcome to look if you want!). Your wound is closed with sutures and covered with a padded dressing .
This is very much your choice. Most patients opt for staged surgery, with a gap of 6-12 weeks between sides. However, it is perfectly feasible to have both sides done simultaneously (Mr Granville-Chapman had both sides done together). The advantage of bilateral surgery is reduced overall time off work, so it may work best for you if you are self-employed. The potential disadvantage is the short-term incapacity from having both hands operated on.
Please elevate your arm for the first 24hrs to reduce throbbing pain and swelling. Do take regular painkillers as soon as you get home and for the first few days. You can take down your bulky dressing on day 3, but should keep the small dressing over your wound and keep it dry for 10 days. Please begin gentle finger and wrist range of movement straight away. Your stitches need to be removed at 10 days after your operation.
You can return to a desk job after a few days, and most people are safe to drive after four days to a week. Your grip will be sore and week for a while, so return to heavier jobs will take a few weeks. The grip strength and soreness on loading the wrist will improve and, for most, this has resolved by three months.
Yes, and most patients report a rapid improvement in night-time symptoms and pins and needles. If you have severe carpal tunnel, with numbness and weakness, then recovery will take much longer and may well be incomplete.
This is a well tolerated and successful operation, but some patients do experience problems:
Infection – this is uncommon and normally settles with antibiotics
Lack of benefit - This is uncommon. Occasionally your median nerve is crushed in your neck as well, this would not be addressed by a carpal tunnel release. It is very rare for inadequate surgical release or nerve damage to have occurred, but very occasionally revision surgery is indicated
Complex regional pain syndrome (CRPS) - A small proportion of patients develop pain, stiffness and swelling in response to injury or surgery to their hand. This rarely happens and is usually recognised early and treated by special painkillers and desensitisation physical therapy. Very occasionally it becomes severe and requires specialist pain doctor referral.
Aching in the wrist is common after carpal tunnel surgery as your hand adapts to the loss of the ligament that was cut. You will also notice weakness of grip for a similar time and have soreness on loading the wrist (press-ups). These symptoms have normally resolved by three months as the ligament heals.
Painful scar - this is a problem for a few patients, but this usually settles with massage and time. You should begin to massage your scar (with a little moisturising cream) from three weeks after your operation. This helps to desensitise the scar.
Your ulna nerve is the one the you may have jolted on the inside of your elbow: it runs just behind the inside knuckle of your elbow and into the forearm. The ulna nerve runs into the hand and gives you sensation in your little and ring fingers and supplies most of the muscles in your hand. Just behind the elbow there is a tunnel through which your nerve runs. This can get tight, or your nerve can be unstable and flip out of position when you bend your arm. Both can result in symptoms. These typically include:
Pins and needles or numbness in your little and ring fingers, often worse at night.
Loss of grip strength and wasting of muscles in your hand
It may also cause pain in your inner arm and forearm
The symptoms and clinical examination are often highly suggestive. Nerve testing (neurophysiology) is useful to characterise the degree of compression and any other compressions in your arm.
If your symptoms are mild and your nerve function is good you may benefit from elbow splinting at night, or an injection. If your symptoms are more intrusive, or they have failed to respond to the splint or injection, you may benefit from surgery. If your nerve testing shows dysfunction it is generally recommended that you have surgery to prevent deterioration, as recovery once hand weakness has set in is unpredictable.
This is done as a day-case under general anaesthetic. A 5-7 cm incision is made over the inside of your elbow. Your ulna nerve is identified and fully released. Sometimes your nerve needs to be ‘transposed’ (moved infront of the knuckle of your elbow) if it is unstable, or in a revision surgery. Your wound is sutured with dissolvable stiches and you have a bulky dressing applied.
You can take down your bulky bandages at 3 days but please leave the small plaster over your wound and keep it dry for two weeks. You can gently move your arm an hand immediately.
Most patients are safe to drive after a week. You can expect to return to desk work after a week, but heavy work may take a few weeks.
Are there any complications?
Infection – this is uncommon and normally settles with antibiotics.
Lack of benefit - This is uncommon. If your ulna nerve has been badly compressed for a long-enough time that the muscle nerve endings in your hand have withered, then your weakness will not recover, but nor should it deteriorate once your nerve is released.
Neuroma - There are small skin-nerve branches that cross the surgical site. While every care is taken, these can sometimes be injured. This may cause a very tender spot in your scar. Very occasionally this does not improve with massage and time and revision surgery to bury the affected nerve is indicated
Complex regional pain syndrome (CRPS) - a small proportion of patients develop pain, stiffness and swelling in response to injury or surgery to their arm or hand. This rarely happens and is usually recognised early and treated by special painkillers and desensitisation physical therapy. Occasionally it becomes severe and requires specialist pain doctor referral.
This is the least common of the three conditions. The posterior interosseous nerve (PIN) supplies your posterior forearm muscles (these extend your wrist, thumb and fingers) and it also supplies sensory (pain) feedback from the wrist. Just beyond your elbow there is a tight band of muscle that can tether and entrap the PIN. Symptoms can be quite vague but generally include:
Aching in the back of your forearm
Weakness and fatigue of grip
Pain over the outer aspect of your elbow
Sometimes mistaken for tennis elbow
Your symptoms and clinical examination are often suggestive
Nerve function testing may be helpful, but it is sometimes normal, despite convincing clinical signs and symptoms. A normal test does not therefore exclude the problem.
A diagnostic injection to numb the nerve may be useful to confirm the diagnosis.
Sometimes imaging such as Ultrasound scan or MRI can help identify a cause of nerve compression (e.g. a ganglion from the elbow joint or a fatty lump near the nerve)
Initially it is worth trying rest, a wrist splint and anti-inflammatories. If these fail then an injection (cortisone) may help. If both of these fail, or if the effect of the injection wears off, then surgery may be indicated.
This is a day-case operation under general anaesthetic. An incision is made over the outer-front aspect of your elbow and down into your forearm to allow your nerve to be traced and released - from its origin to beyond any sites of compression. Your wound is closed with dissolving stitches and covered with a bulky dressing
You can take down your bulky bandages at 3 days, but please leave the small plaster over your wound for two weeks. You can gently move your arm an hand immediately.
Most patients are safe to drive after a week. You can expect to return to desk work after a week or so, but heavy work will take a few weeks.
This is a well tolerated successful operation, but some patients do experience problems:
Lack of benefit - this is uncommon, but sometimes other causes of pain in the region may co-exist (neck nerve entrapment). If your nerve has been badly compressed for a long-enough time that the muscle nerve endings in your hand have withered, then your weakness will not recover, but nor should it deteriorate once your nerve is released.
Nerve injury - The posterior interosseous nerve is small and fragile. Every care is taken to protect your nerve, and injury to your nerve during surgery is rare. If the nerve gets bruised, then it may turn off for a while, but it should recover. However a cut nerve does not normally recover on its own. If the nerve were to stop working permanently, then other surgery (tendon transfer or nerve exploration and grafting) might be required to restore your finger function
Complex regional pain syndrome (CRPS) - a small proportion of patients develop pain, stiffness and swelling inresponse to injury or surgery to their arm or hand. This is usually recognised early and treated by special painkillers and desensitisation physical therapy. Occasionally it becomes severe and requires specialist pain doctor referral.
Mr Granville-Chapman was very polite and his examination and explanation of my symptoms and expected treatment was thorough
I found Mr Granville-Chapman to be very knowledgeable and professional. He put me very much at ease and explained all the options that I have thoroughly. He also told me to look for further information on the condition and procedures that I needed on his website, which gave lots of information and detail. It was also easy to understand for those without a medical background. I would highly recommend his services to anyone that has shoulder problems and requires a solution.
I attended for a repair of my right bicep tendon. After a thorough examination, Mr Granville-Chapman arranged an operation to be undertaken within 2 days which was extremely quick; he explained his reasoning which was both thorough and reassuring, explaining both the options of undergoing surgery and deciding to undertake conservative management.On the day of the surgery Mr Granville-Chapman was again very reassuring as although this is minor surgery I was still somewhat apprehensive. He came to fully explain the procedure and afterI woke up was quick to check on how I was doing.Overall I am very happy with the careMr Granville-Chapman
I have been very pleased with my treatment so far. Mr Granville-Chapman combines brisk efficiency with a pleasant, sympathetic manner. My operation, however, is still to come ...
From the initial consultation, through surgery on a fractured wrist, and now post-operative follow up, it has been a very positive and reassuring experience with Mr Granville-Chapman. I would have no hesitation in recommending him to someone else.
A first class clinician. A skilled surgeon with an excellent bedside manner.
A very pleasant Consultant who knows exactly how to make pain go away.
Mr Granville - Chapman has an excellent bedside manner. He engaged with my 12 year old son at an appropriate level and took the time to ensure that he understood the procedure and answer all his questions. He is thoroughly professional and I would not hesitate to recommend him.
I have been very pleased with the attention I have received. Mr. Granville-Chapman has reassured me that my symptoms are normal. It is very easy to make appointments that suit me.
Mr Granville chapman I found be caring informative and professional I would recommend him to all if you have a problem don't hesitate to contact him you won't be disappointed.
I recently broke my right clavicle in a mountain bike accident and it was repaired by Mr Granville-Chapman by adding a plate on top of the bone. Having just finished the last post-op consultation, I can confirm that I have been very happy with the process all along. In particular, Jeremy took time to explain in detail why a plate was needed, what the procedure would entail, and also was very patient answering my questions comprehensively beforehand and after during the recovery phase. Would certainly trust this competent surgeon to fix any future fractures I might sustain.
Mr Granville-Chapman has looked after my 15 year old son brilliantly, explaining the surgery, recovery and best way forward, and Kate has been very supportive helping with logistics etc, thank you so much.
So far my experience with Mr Jeremy Granville-Chapman has been personal and informative with regard to the operation I will be having. I feel confident that my operation will be a success and for this reason I am very happy to have Mr Jeremy Granville-Chapman as my consultant.
Very knowledgeable and helpful. Takes the time to make sure you're getting the treatment you need.
Mr Jeremy Granville -Chapman is not only a highly skilled consultant but is able to put you straight away at ease .My appointments were arranged very swiftly which was great, when you are experiencing severe pain. I am very happy with my treatment so far . many thanks to everyone who was involved in my treatment.
Polite, helpful, professional. Makes an effort to ensure full understanding of issues and procedures to be done. Highly satisfied
Very pleasant. Clear, careful explanations & options/possibilities. I feel well informed, and happy that my concerns are being well addressed, with a plan of review of the symptoms.
Excellent advise with everything explained clearly and a successful treatment which has benefited be greatly.
