How Long for AC Joint Sprain to Heal

How Long Does It Take for an AC Joint Sprain to Heal?

AC joint sprains, also known as shoulder separations, are common injuries that can occur from falls, sports accidents, or other trauma to the shoulder area. They involve the stretching or tearing of the acromioclavicular (AC) ligament, which connects the collarbone to the shoulder blade. One of the most common questions people ask when diagnosed with an AC joint sprain is how long it will take to heal. While each case may vary, there are general guidelines regarding the timeframe for recovery.

The healing process for an AC joint sprain typically consists of three phases: the acute phase, the subacute phase, and the chronic phase. The acute phase lasts for the first few days after the injury and involves managing pain and inflammation. During this phase, it is crucial to rest the shoulder, apply ice, and take anti-inflammatory medications as prescribed by a healthcare professional.

The subacute phase usually begins after the first week and can last for several weeks. In this phase, physical therapy exercises to restore range of motion and strengthen the shoulder muscles are introduced. This phase focuses on regaining strength, stability, and function.

The chronic phase occurs after the initial healing process and can last for several months. During this phase, patients may continue with physical therapy to further improve strength and range of motion. Gradually, they can resume their normal daily activities and return to sports or other physical activities.

2. How long does it take for a mild AC joint sprain to heal?
Mild AC joint sprains typically heal within 4-6 weeks with appropriate rest, ice, and physical therapy.

3. What about severe AC joint sprains?
Severe AC joint sprains that involve complete ligament tears may require surgical intervention and a longer recovery time, ranging from 3-6 months.

4. Can I continue to exercise during the healing process?
It is best to avoid any activities that put stress on the shoulder joint during the acute phase. However, as healing progresses, your healthcare provider may recommend specific exercises to aid in recovery.

5. Can I wear a sling to support my shoulder?
A sling may be recommended during the acute phase to provide support and reduce stress on the injured joint.

6. When can I return to sports or physical activities?
The timing for returning to sports or physical activities varies depending on the severity of the sprain and the individual’s progress. It is vital to follow your healthcare provider’s advice and gradually reintroduce activities to avoid reinjury.

7. Can I prevent future AC joint sprains?
While it may not be possible to completely prevent AC joint sprains, maintaining good shoulder strength and stability through regular exercises can reduce the risk.

8. Should I continue physical therapy after the sprain has healed?
Continuing physical therapy exercises even after the sprain has healed can help improve strength, range of motion, and prevent future injuries.

9. What can I do to relieve pain during the healing process?
Using ice packs, taking over-the-counter pain medications, and following your healthcare provider’s recommendations for pain management can help alleviate discomfort.

Depending on your type of work and the severity of the sprain, you may need to modify your work activities or take time off to allow for proper healing.

11. When should I seek medical attention for an AC joint sprain?
It is recommended to seek medical attention if you experience severe pain, persistent swelling, inability to move the shoulder, or if symptoms worsen despite conservative treatment.
