Total Shoulder Replacement

In conditions where the joint surface in a shoulder is worn out or damaged the joint surfaces can be replaced to address the problem

Conditions include

Osteoarthritis (wear and tear that causes loss of cartilage and eventually bone on bone contact in the shoulder)
Arthritis after a fracture or an injury (post traumatic arthritis)
Conditions where the bone in the shoulder collapse due to poor blood supply (avascular necrosis)
Where inflammation has destroyed the joint (conditions such as Rheumatoid arthritis)
To have a successful anatomic shoulder replacement the ROTATOR CUFF in the shoulder must be in good condition or repairable.

If there is a tear in the rotator cuff it may be better to have reverse total shoulder replacement – Please see separate information sheet.

The shoulder gradually becomes more painful over time.
Sometimes a minor injury or overuse can make a worn out shoulder a lot more painful for a long time
The shoulder becomes more and more stiff. It can become hard to reach behind your back or reach the back of your head.
There can be cracking and grinding when the shoulder is moved

Lifestyle adjustment
Avoid activities that aggravate the shoulder
Find different ways to do essential activities.
Exercises and Physiotherapy
The aim is to maintain the range of motion that is left in the shoulder
And to maintain strength in the shoulder
Exercises need to be done carefully, because done excessively it can make the situation worse
Medication such as paracetamol and anti inflammatories
Please check with your normal doctor to make sure that it is safe for you to take these tablets long term.
Injections into the shoulder joint
Can sometimes give long lasting relief
Regular injections are not advised.
Should not be done within 3 months of planned shoulder surgery.

Where non operative treatment is unsuccessful and
The injury stops you from doing the ‘things that you have to do’ such as getting dressed, making a meal, driving a car, or getting a good night’s sleep
and/or the ‘things that you love to do’ in life such as fishing, riding a bicycle, or holding a book to read.
You are generally well enough to undergo surgery
You are willing to accept the recovery time and long-term limitations of a shoulder replacement

This kind of surgery usually requires a General anaesthetic (being ’completely knocked out’)
Often the anaethetist does a nerve block (that numbs and paralyses the arm for about 12 hours) to help with pain relief – it can be very painful surgery.
Because it is significant surgery- It is recommended to stay in hospital for a day or two
Antibiotics is usually administered at the time of surgery but does normally have to be continued after surgery.

Surgery usually takes about 2 hours
But the whole process of going to theatre and waking up from surgery takes longer.
There is usually around a 10cm incision on the front of the shoulder
The worn-out joint surfaces and any bone spurs are removed and replaced with a special plastic cup and metal or ceramic ball.
Tendons and tissue around the shoulder that had to be released to do the surgery are sutured.

In Hospital

The wounds are dressed, and the arm is placed in a sling
We often leave a pain catheter in the shoulder to deliver more local anaesthetic at about 10 hours after surgery (when the anaethetist’s nerve block starts to wear off)
Do not hesitate to ask for pain killers. It is much better to ‘stay on top of pain’, than ‘to catch’ up when it is severe.
It is usual to leave hospital the day after surgery, or on the second day after surgery
A physiotherapist will usually visit you in hospital to demonstrate gentle exercises.

At Home

Continue to stay on top of your pain with oral pain killers.
Do the gentle exercises that physiotherapist demonstrated in hospital. It is usually advised to see a physiotherapist in the community at around 4-6 weeks post surgery.
It is OK to remove your sling to do these exercises, but in most cases, it should stay on at all other times for 6 weeks.
While the shoulder wounds are covered with waterproof dressings it is safe to have a shower. Please have the dressings replaced if they start to come loose.
An appointment is usually made at my rooms to review your progress at about 2 weeks after the surgery
Please do not drive before speaking to your physiotherapist or a doctor.
If there is any concern about infection, please contact my rooms
Please ask you doctor to contact me before starting antibiotics.

A sling is usually worn for about 4-6 weeks.
From around 4 weeks on, a physiotherapist will show you how to start to progress your range of motion exercises.
From 6-12 weeks sling wear can be weaned shoulder movements increased under physio supervision.
Most moderately activities can usually be achieved by 3-4 months, but it will take 6 -9months to become completely comfortable and to return to maximal effort.
It often takes up to a year to regain completely maximal range of motion.

Time frames

Self care (washing, dressing, eating) with the operated arm – usually around 4-6 weeks (a sling may still be needed)
Driving: when you are able to control a steering wheel with your operated arm and you are not taking strong pain relief anymore (usualy 6-8 weeks post surgery)
Golf, fishing, cycling etc.: usually around 3-4 months, but it can be longer (6 months)

Infection occurs rarely(1% of the time), but can be severe. It may need further operations, weeks in hospital. It can lead to a poor outcome.
There may be ongoing pain from other worn out joints in the area, that were not obviously a problem at the time of doing the surgery.
It is common to have a bit of numbness next to the scar. Very rarely, severe nerve damage can occur, resulting in paralysis or numbness in the arm.
Significant bleeding can occur during surgery. A blood transfusion can occasionally be needed and very rarely it can be life threatening.
Although most shoulder replacements last more than 10 years, some can become loose or wear out sooner than expected.
The bones around the replacement can break
Just like in a normal shoulder, the rotator cuff tendons can tear, which can lead to pain and early loosening of the replacement.
A general anaesthetic can have complications, such as nausea, heart and lung problems. Please discuss it with your anaesthetist before the operation.

The large majority of patients experience significant improvement in their shoulder pain and function.
Mild discomfort and stiffness persist despite successful surgery.
Strength usually recovers, but it can take up to 2 years to reach maximal improvement.
Movement in the shoulder usually improves a lot, but may not be normal
The best indication of how a shoulder will move is the pre-operative range (i.e. very stiff shoulders are expected to improve a lot, but usually still have less movement than shoulders that had better movement before surgery)

How long will the surgery take / How long will I be in hospital?

about 2 hours, overnight

Which hospital?

The Sunshine Coast University Private Hospital

Anything I should do to prepare for surgery?

You should make sure that she has no pimples or skin breaks around your shoulder.
if there are any pimples she should wash with benzoil peroxide.
Stop any drugs or supplements that may cause thinning of blood (anti inflammatories, fish oil etc.)
Make sure that you have help at home for after surgery; you will need a sling for 6w and cannot drive for at least 6w
don't smoke

After care - showering, etc?

as long as waterproof dressings are securely in place

Will I be in a sling?

yes for 6w

Worst case scenario?

Infection can make the shoudler worse than is now, it may never recover (there is less than 1% risk of this happening)
Very rarely serious complications can occur from the anaesthetic, such as a stroke or heart attack.
Ther is a very small risk of death

Are there limitations on what I can do after surgery?

Very heavy constant labor is not advised (occasional garden work, home maintenance etc is ok)
Activties with a high risk of a violent fall or impact is not advised (eg. Motocross, downhill mountainbifing, contact sport)
Regular exercise is OK but heavy or high-volume activity (such as swimming more than 2km a day) is not advised.
