A sprain of the acromioclavicular (AC) joint occurs when there is damage to the ligaments that hold the AC joint together. This type of injury most commonly occurs in athletes who participate in contact sports, but can also happen due to a fall or other trauma.
When a sprain occurs, the ligaments that connect the clavicle (collarbone) to the scapula (shoulder blade) are stretched or torn. This can cause pain, swelling, and difficulty moving the shoulder.
If you have experienced a sprain of the left AC joint, it is important to seek medical attention. Your doctor will likely recommend rest, ice, compression, and elevation (RICE) to help reduce pain and swelling. They may also prescribe pain medication and recommend physical therapy to help restore range of motion and strength to the shoulder.
Physical therapy may be recommended to help restore range of motion and strength to the shoulder. This may include exercises to stretch and strengthen the muscles surrounding the AC joint, as well as manual therapy techniques to improve joint mobility.
In severe cases, surgery may be necessary to repair the damaged ligaments and restore stability to the AC joint. Your doctor will discuss the best treatment options for your individual case.
It is important to take steps to prevent future AC joint sprains by wearing appropriate protective gear during sports and activities, and by practicing proper lifting technique.
