The elbow consists of the upper arm bone ('humerus') and two bones in the forearm ('ulna' and 'radius'). See picture below. The elbow works in two parts. One part acts as a hinge enabling you to bend and straighten the elbow. The second part provides rotation or pivoting of your forearm; for example to put your palm up towards the ceiling to receive 'change' in a shop. The joint has muscles which move it and also some nerves that pass close by (hitting your 'funny bone' gives a nerve sensation into the forearm and/or fingers).
The most common reason for replacing the elbow joint is for arthritis, usually rheumatoid arthritis. However it may be necessary with osteo-arthritis (wear and tear) and following a fracture or bad accident.
The operation replaces the damaged joint surfaces. There are many different types of elbow replacement. They usually consist of metal and plastic. The surfaces are replaced to give a hinge joint. In addition the top of one of the forearm bones (radius) is removed as this joint can also give elbow pain. See picture below. To get into the joint, the muscle on the back of your arm (triceps) is split and cut away from the bone. This is then re-stitched at the end of the operation.
The main reason for doing the operation is to reduce the pain in your elbow. Ultimately you may also have more movement in your elbow. Bending your elbow to allow your hand to reach your mouth and rotating the forearm usually show the greatest improvement. However, your arm may not straighten-out more after the operation.
This type of joint used by Mr Shahane in most patients is called the "Coonrad-Morrey" total elbow replacement. This has a documented long term follow-up. If you would like to know more details about the prosthesis you should ask your surgeon at your pre-assessment visit.
All operations involve an element of risk. We do not wish to over-emphasise the risks, but feel that you should be aware of them. They include:
Please discuss these issues with the doctors if you would like further information.
Although the operation is to relieve pain, it may be several weeks until you begin to feel the benefit. You will be given pain-killers (either as tablets or injections) to help reduce the discomfort whilst you are in hospital. A prescription for continued pain medication will be given to you for your discharge home. Please visit your General Practitioner (GP) if you require further medication after that.
You will probably have some bruising around the elbow and the arm may be swollen. These will gradually disappear over a period of a few weeks.
You may find ice packs over the area helpful. Use a packet of frozen peas, placing a piece of wet paper towel between your skin and the ice pack. Until the wound is healed, also use a plastic bag to protect the wound from getting wet. Leave on for 10-15 minutes and you can repeat this several times a day.
The sling is to protect the elbow replacement. You will keep it on most of the time for the first 3 weeks. You do not need to have your arm strapped to your body. You will take the sling off for most of the exercises. If you are sitting and resting you may take the sling off if you wish. The therapists and nurses will show you how to use the sling.
You will gradually wear the sling less after 3 weeks, but you may find it takes 6 weeks or more, before you are without it all the time. You may find it helpful to wear the sling at night (with or without the body strap), particularly if you tend to lie on your side. Alternatively you can use pillows in front of you to rest your arm on (please see picture overleaf).
In addition if you are lying on your back to sleep you may find placing a thin pillow or folded towel under your arm will be comfortable.
Yes! You will be shown exercises by the physiotherapist. You will start exercises to move the elbow, from the third day after the operation. You will then need to continue with exercises when you go home. Outpatient physiotherapy is not routine, but will be organised.
You will need to get into the habit of doing regular daily exercises at home for several months. They will enable you to gain maximum benefit from your operation.
The exercises aim to stop your elbow getting stiff and strengthen muscles. Some exercises are shown at the back of this booklet.
Keep the wound dry until it is healed. This is normally for 10-14 days. You can shower or wash and use ice packs but protect the wound with cling-film or a plastic bag. Do not get the wound wet. Avoid using talcum powder or perfumes near or on the scar.
Normally your stitches will be removed during your visit to the hospital in approximately 2-3 weeks after surgery.
This is usually arranged for approximately 2-3 weeks after you are discharged from hospital. Please discuss any queries or worries you may have when you are at the clinic. Appointments are made after this as necessary.
For 6 weeks
Do not try and push or force your elbow straight. For example pushing through your arm to get from sitting to standing, pushing a door open, polishing surfaces. This is because the muscle (triceps) has been cut and re-stitched in the operation. It takes time to heal before you can put force through it. Even after 6 weeks, take care of this action. However, it is important you do practise trying to straighten your arm as the therapist shows you, just don't use your muscle power to do it!
Try to avoid twisting the elbow with your arm out to the side.
For example reaching back to get your seat belt in a car and in the 'throwing' (e.g. a ball) action.
For the rest of your life
It is not known exactly what may cause the elbow replacement to become loose, but it is advised that you try to avoid:
heavy manual work
lifting objects with weight over 4 Kg or
forceful pushing and pulling activities.
This will result in you being unable to do heavy gardening (e.g. digging). If your dominant arm has been operated on you are advised not to do sports such as bowls (or else learn to use your non dominant arm). You are advised not to play golf after elbow replacement. The therapists will be able to advise you on ways to avoid unnecessary stress and strain on your elbow.
This can be divided into four phases:
Phase 1. Immediately after the operation until you are discharged from hospital
For the first 2 days after your operation your arm is in plaster. The plaster is removed after 48 hours, the wound inspected and a splint may be used to try and keep your arm straight. You will start to move the elbow with the help of the physiotherapist, but to begin with you will be quite one-handed. If your dominant hand (right hand if you are right-handed) is the side with the operation your daily activities will be affected and you will need some help. The splint is discarded after 3-4 weeks.
Activities that are affected include dressing, bathing, hair care, shopping and preparing meals. The occupational therapist will discuss ways and show you how to be as independent as possible during this time. Some common difficulties which are encountered with examples of practical solutions to help are listed in a section later in the booklet ('Guides to daily activities' page 12).
Before you are discharged from hospital, the staff will help you plan for how you will manage when you leave. Please discuss any worries with them. We may be able to organise or suggest ways of getting help for when you are home.
Phase 2. After you have been discharged and for the next 6 weeks
The pain in your elbow will gradually begin to reduce. Wean yourself out of the sling slowly over this time. Do not be frightened to try and use your arm at waist level for light tasks and to try and move your hand towards your face. Remember not to push your arm straight.
You will be asked to do exercises at home to get the joint moving, you will also see a physiotherapist as an outpatient.
Phase 3. Between 6 and 12 weeks
The pain should be lessening. You may not be using the sling at all or will have reduced the amount of time that you have it on. You can start to use the arm with more force but remember the precautions that you need to take for the rest of your life. Overall, you will have an increasing ability to use your arm for daily tasks (see driving, work and leisure sections later).
Phase 4. After 12 weeks
Hopefully by this stage you should begin to feel the benefits of the operation. The pain in the elbow joint should be much less than before your operation. In addition you may find that daily tasks are easier to perform. You may still have an elbow that will not go straight, but the other movements often improve. Most improvement will be felt in the first 6 months and this is normally maintained.
You will probably be off work approximately 6-8 weeks, depending on the type of job you have. If you are involved in overhead activities you are advised not to do these for 3-6 months. You may be advised to change your employment if you have to do lifting or heavy manual work. Please discuss any queries with the therapists or hospital doctor.
It is normally about 6-8 weeks before you can do this safely. You may find it is more difficult if your left arm has been operated on because of using the gear stick/handbrake. Check you can manage all the controls and it is advisable to start with short journeys.
In addition, check your insurance policy. You may need to inform the insurance company of your operation.
Your ability to start these activities will be dependent on pain, range of movement and strength that you have in your elbow following the operation. Please discuss activities that you may be interested in with the therapists or hospital doctor. Start with short sessions, involving little effort and gradually increase.
Swimming after 6 weeks
Gardening (light tasks e.g. weeding) after 6-8 weeks
(NB. Heavier tasks e.g. digging - do not do!)
Some difficulties are quite common, particularly in the early stages. The occupational therapist (O.T.) will help you to be as independent as possible during your rehabilitation. Special equipment can be borrowed from the O.T. department. Often other joints may be causing problems with pain and stiffness. Everyone is different so your individual needs will be assessed.
We appreciate that you may have been having many of these problems before your operation.
Please discuss your difficulties with the occupational therapist.
Use pain-killers and/or ice packs to reduce the pain before you exercise.
It is normal for you to feel aching, discomfort or stretching sensations when doing these exercises. However, if you experience intense and lasting pain (e.g. more than 30 minutes), it is an indication to change the exercise by doing it less forcefully, or less often. If this does not help, discuss the problem with the physiotherapist.
Certain exercises may be changed or added for your particular elbow. Do short, frequent sessions (e.g. 5-10 minutes, 4 times a day)rather than one long session. Gradually increase the number of repetitions you do. Aim for the repetitions your therapist advises, he numbers stated here are rough guidelines.
After 3-4 weeks you can increase the length of time exercising.
Get into a habit of doing them! Good luck.
Rest your forearm on a flat surface. Try and turn your palm up towards the ceiling. Then turn palm down. Repeat each movement 5 times.
These exercises are important, especially the bending part. It can be done in different positions. The therapist will help you to find the most useful for you.
2. shown for left arm
Lying on your back, arm supported. Let your arm go straight. DO NOT PUSH it straight. Just 'let it go'. Repeat 5 times.
3. shown for left arm
Lying on your back. Rest upper arm on bed on small pillow. Use your other arm to help your hand towards your mouth. Gradually do this without using the other arm for help. Repeat 5-8 times.
(6 weeks after your operation) You can now start using the triceps muscle.
1. Lying down.
Rest your hand on your forehead. Then try and straighten your arm up in the air. Repeat 5 times.
Sitting or standing.
Arms by your side. Try and straighten your arm and then put a little weight through it. Do not let the arm buckle. Do not push hard. Repeat 5 times.
3. Sitting or standing.
Try and place you hand behind your head.
Do exercises that you feel will help you to do the things that you wish to do in your life. Not all of these exercises may be required. Do not do weight lifting type exercises unless directed by a therapist. If the movement does not change within 12 weeks, it may not change further. This will be the movement that you will have for daily activities.
If your wound changes in appearance, weeps fluid or pus or you feel unwell with a high temperature, contact your GP.
If you have a query about exercises or movements, contact the Physiotherapy department where you are having treatment if you have already started.
