Suprascapular nerve decompression Info Consent

Why this operation has been suggested
This page reflects how Dr Kieran Hirpara, an upper-limb surgeon at Mater Private Hospital Rockhampton, approaches this in our clinic. You reach our clinic by GP or physiotherapist referral. A clinic assessment establishes the diagnosis. We usually try non-operative care first — activity change, physiotherapy, and injections — and consider surgery when that has not given enough improvement. For structural problems, surgery may be recommended straight away.
We suggest arthroscopic suprascapular nerve decompression when you have nerve compression causing pain or weakness. This keyhole procedure uses two or three small incisions and a small camera inside the joint to release pressure on the nerve. It is typically offered when non-operative options have failed or when there is clear mechanical compression. The main benefit is relief of pain and a return of normal shoulder function.
Before the operation
We prepare you for a keyhole surgery using two or three small incisions and a tiny camera. Please fast for six hours before your arrival. Stop blood thinners only after your surgeon gives specific instructions. Arrange a lift home and bring a list of all current medications. Wear comfortable, loose clothing. You may need X-rays, an MRI, blood tests, or an anaesthetic review. These checks ensure your body is ready and help us plan the safest approach for your shoulder.
On the day
You will arrive at the hospital for admission. Your surgeon will meet you to confirm the plan. This operation is done under general anaesthetic combined with a regional nerve block. You will be fully asleep for the operation, and the block — an injection that numbs the nerves supplying the arm before you wake up — provides pain relief for the first 12 to 24 hours after surgery. The anaesthetist will meet you before the operation and talk you through both parts.
We perform this procedure using an arthroscopic approach. This means we use keyhole surgery with two or three small incisions. A small camera allows us to see inside your shoulder joint clearly. This method helps us address any other shoulder issues at the same time. After the procedure, you will wake up in recovery. Our team will monitor you closely as the anaesthetic wears off. You can expect significant pain relief from the block during your first day home. We will guide you through your next steps before you leave.
What the operation involves
We perform this surgery using an arthroscopic (keyhole) approach. This means we use two or three small incisions rather than one large cut. Through these small openings, we insert a tiny camera and specialized instruments into your shoulder joint. This setup gives us a clear view of the area while allowing us to address any other shoulder issues at the same time.
Your surgeon will locate the suprascapular nerve, which runs through narrow tunnels of tissue in your shoulder blade. If this nerve is being squeezed or trapped, we gently release it by cutting the tight bands of tissue or ligaments that are pressing on it. We also carefully identify and protect the suprascapular artery, which runs right next to the nerve, to ensure your safety during the procedure.
In some cases, we may use the top edge of your shoulder blade as a guide to help us work more efficiently. Once the nerve is freed and any other necessary repairs are complete, we close the small incisions with sutures (dissolving or removable stitches) or medical glue. A dressing is then applied to cover the sites. This approach allows us to treat the nerve compression directly while minimizing damage to the surrounding tissues.
After the operation
You will wake up in the recovery ward. We manage your pain with standard medication. Your shoulder is supported in a sling, and a sterile dressing covers the small incisions. Most patients stay one night in hospital after this operation, though some are able to go home the same day. You must have someone stay with you for the first 24 hours. Do not drive for at least SIX WEEKS after any shoulder operation, regardless of which arm was operated on. You must not drive while in a sling. Once your surgeon clears you, typically at the six-week review, you may resume driving. For more details, see Driving after upper-limb surgery.
Recovery
You will have two or three small keyhole incisions. A tiny camera helps your surgeon guide the tools inside your shoulder. This approach lets us see the nerve clearly while protecting nearby blood vessels. You will wear a sling to keep your arm still while the swelling settles.
Your shoulder may feel sore and tight in the first few days. This is normal. We manage this with prescribed pain relief and rest. Ice packs can help reduce swelling. You will sleep with extra pillows to keep your arm supported. Gentle movement of your fingers and elbow is encouraged to keep blood flowing, but your shoulder stays protected.
As the initial ache fades, your physiotherapist will guide you through gentle exercises. These start with simple pendulum swings to keep the joint loose. We focus on restoring range of motion before building strength. You will avoid heavy lifting or reaching overhead until your surgeon clears you.
Driving is not permitted for at least six weeks after any shoulder operation, regardless of which arm was operated on. You must not drive while wearing a sling. Once your surgeon clears you, typically at the six-week review, you may resume driving. See our guide on Driving after upper-limb surgery for more details.
Recovery varies between individuals. Your timeline may differ; your surgeon and physio will guide you based on how your shoulder responds to treatment.
What can go wrong
Most patients do well, but problems can occasionally happen. Your surgeon and the team monitor you closely to spot any issue early.
During your keyhole surgery, we work through two or three small incisions using a tiny camera. We must protect the suprascapular artery, which runs alongside the nerve. If this blood vessel is irritated, you might notice unusual bleeding or a strange sensation in the shoulder area. If you see significant swelling or feel a pulsing pain near the incision sites, call our clinic immediately. We need to check that the blood flow is normal and that there is no internal bleeding.
Sometimes, the natural shape of your shoulder bones or ligaments can make the nerve tight. This is called an anatomical variation. If the nerve remains compressed after surgery, you may feel a deep ache or weakness in your shoulder. You might find it hard to lift your arm or rotate it outward. If this pain does not ease with simple painkillers, bring it up at your next review. We can assess whether the nerve is still under pressure.
In some cases, the nerve might not recover fully even if the surgery goes well. You might notice that your shoulder strength does not improve as much as you hoped. Pain relief might also be partial. While the pain often gets better, any muscle wasting or fatty changes in the shoulder tissue will not reverse. If you feel disappointed with your progress or notice no change in pain after a few weeks, let us know. We can discuss what to expect next and adjust your recovery plan.
