Collar bone (acromioclavicular joint) sprain (182kB pdf)
Introduction
We hope this guide will answer your questions about your shoulder injury. Please contact the team if you require further information via the details at the end of this leaflet.
What is an acromioclavicular joint sprain?
You have a sprain (partial disruption of ligament fibres) of the joint between the shoulder blade and collar bone.
How long will this take to heal?
This injury almost always heals well with time and use. Symptoms are usually minor, but may take up to eight weeks to settle.
Will I need follow up?
Routine follow up is not necessary due to the nature of the injury.
Are there any complications?
There may be slightly reduced movement at the shoulder, especially when lifting the arm, but this is likely to improve over time with normal use.
Is there anything to avoid?
You should avoid lifting anything heavy for up to three months.

How will this be managed?
A sling (arm support) will hold your shoulder in a comfortable position for a few days. You should wean yourself off this as your pain settles and aim to remove the sling completely as soon as you feel able.
What can I do to aid recovery?
- Painkillers
- Gently move the shoulder (see exercises)
- Gradually resume daily activities
This will help prevent stiffness and ensure quick recovery. Forcible stretching is unnecessary, and is likely to cause pain and delay your recovery
