The Acromio Clavicular joint (AC joint) is part of the shoulder complex. It is situated at the outer side of the Collar bone where it is attached to the front of the shoulder blade with strong ligaments.
An AC joint sprain (Shoulder Separation) refers to damage to these ligaments. The AC joint ligaments are most commonly damaged through a fall onto either the tip of the shoulder or a fall onto an out stretched hand.
Similar to a broken Collar bone - try to make sure you don't fall! Avoiding an 'Endo' is very important, especially during fast descents. If your front wheel comes to an abrupt halt then you're likely to go flying over the handlebars.
Keep an eye out for rocks and tree stumps as these are the most common causes of a fall. Always make sure that your pedals are level with your weight distributed evenly between left and right pedal, because if you're unbalanced then you're more likely to go over the handlebars.
Apply Ice Packs (never apply ice directly to the skin) to the shoulder for pain relief. Pain killing drugs prescribed by a doctor can provide relief for the intense shoulder pain. A Figure of 8 Shoulder Support and Sling can immobilise the shoulder and provide pain relief.
The Mueller Shoulder Brace will push the collar bone downwards and provide the support of a sling. When returning to activity the Donjoy Shoulder Stabiliser will provide support and protection that can help to prevent re-injury.
