Hi,
An
acromioclavicular joint separation, or AC tear, is a frequent
injury seen among physically active people. In such injury, the
clavicle (collar bone) separates from the
scapula (shoulder blade).
Grade I or 1st-degree tear means that there is a slight displacement of the joint. The acromioclavicular ligament may be stretched or partially torn. Generally, most AC injuries don't require surgery.
The vast majority of patients will have a period of discomfort. Once this discomfort disappears, the shoulder usually becomes fully functional.
Application of ice packs is needed to reduce pain and swelling. Rest and a protective sling until the pain subsides for about 1-2 weeks.
Pain and anti-inflammatory medications need to be taken. By above measures, it usually takes about 2 weeks for a grade I injury or 1st-degree tear and 6 weeks for a grade II injury or 2nd-degree tear, to heal completely.
A
rehabilitation program to restore normal motion and strength is begun as soon as the pain becomes tolerable with gentle exercises and progresses as healing allows.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Ashakiran S, General & Family Physician
