An AC joint injury is usually treated with rest, and activity modification in mild cases. If pain persists, ultrasound-guided cortisone injections can reduce inflammation, while ultrasound-guided hyaluronic acid injections may improve joint lubrication and relieve chronic AC joint pain.
How Do You Treat an AC Joint Injury?
An acromioclavicular (AC) joint injury, often called a shoulder separation, affects the small joint at the top of the shoulder where the collarbone meets the shoulder blade. It commonly causes pain at the top of the shoulder, particularly after a fall or sporting injury.
Treatment depends on the severity of the injury and whether symptoms persist.
At Alton Pain Clinic, we specialise in ultrasound-guided AC joint injections, offering both cortisone and hyaluronic acid treatments for ongoing shoulder pain.
Initial Treatment for an AC Joint Injury
For mild AC joint sprains (Grade I–II), treatment typically includes:
- Rest and temporary activity modification
- Ice to reduce swelling
- Simple pain relief
- Avoiding heavy lifting or cross-body movements
Many mild injuries improve within 2–6 weeks.
When Pain Persists
In some cases, inflammation continues even after the ligaments have healed. This may lead to:
- Ongoing tenderness at the top of the shoulder
- Pain when reaching across the body
- Discomfort during overhead movement
- Night shoulder pain
Persistent symptoms may indicate chronic AC joint inflammation or early AC joint arthritis.
Treatment We Offer at Alton Pain Clinic
1. Ultrasound-Guided Cortisone Injections
Cortisone is a powerful anti-inflammatory medication injected directly into the AC joint under ultrasound guidance.
Benefits:
- Rapid reduction in inflammation
- Effective pain relief
- Improved shoulder movement
- Helps settle flare-ups
Ultrasound guidance ensures precise placement within the small AC joint, improving accuracy and effectiveness.
2. Ultrasound-Guided Hyaluronic Acid Injections
Hyaluronic acid acts as a lubricant within the joint. It is particularly beneficial in:
- Post-traumatic AC joint pain
- Degenerative AC joint arthritis
- Chronic joint irritation
Benefits:
- Improved joint cushioning
- Reduced friction
- Longer-lasting relief in selected cases
This treatment can be especially helpful when inflammation has settled but joint irritation persists.
When to Seek Specialist Treatment
You should consider assessment if:
- Pain persists beyond 6 weeks
- There is ongoing tenderness at the top of the shoulder
- Sleep is disturbed
- Daily activities remain limited
At Alton Pain Clinic, we provide ultrasound-guided AC joint injections in Alton to accurately target the source of pain and optimise recovery.
