AC Joint Dysfunction

Pain at the very top of your shoulder can make everyday activities like reaching overhead, lifting, exercising, or even sleeping uncomfortable. One possible source of that pain is the acromioclavicular (AC) joint.

At Vertical Chiropractic in Redding, California, we look beyond simply where you feel pain. Through a Gonstead chiropractic approach and specific extremity adjustments, we evaluate how the joints of the shoulder and surrounding areas are moving and functioning together.

What Is the AC Joint?

The acromioclavicular, or AC, joint is the small joint where the end of your collarbone (clavicle) meets part of your shoulder blade (acromion). It sits at the very top of your shoulder and plays an important role in allowing the shoulder blade and arm to move properly.

The AC joint is a gliding joint that helps coordinate movement of the shoulder complex. Because the shoulder depends on several interconnected joints and structures, dysfunction in one area can influence how the rest of the shoulder moves.

What Causes AC Joint Dysfunction?

AC joint problems can develop for several reasons, including:

  • Falls or direct impact to the shoulder

  • Sports-related injuries

  • Repetitive overhead activities

  • Weightlifting

  • Repetitive work

  • Joint degeneration and arthritis

  • Altered shoulder or scapular mechanics

AC joint injuries can range from mild sprains to more significant separations or ligament injuries. The AC joint can also develop degenerative changes over time, particularly with repetitive stress.

What Does AC Joint Dysfunction Feel Like?

Symptoms can vary depending on the cause and severity of the problem. Common complaints may include:

  • Pain directly over the top of the shoulder

  • Shoulder stiffness

  • Pain when lifting the arm

  • Pain when reaching across the body

  • Tenderness around the AC joint

  • Reduced shoulder movement

  • Swelling or a visible bump following an injury

AC joint pain can sometimes be difficult to distinguish from other causes of shoulder pain, which is why a thorough examination is important.

How Can Gonstead Chiropractic Help?

A Gonstead chiropractic approach looks at the spine and extremity joints as part of an interconnected system. Instead of focusing exclusively on the location of pain, the goal is to identify areas where joint motion and mechanics may not be functioning optimally.

At Vertical Chiropractic, an examination may include posture evaluation, static and motion palpation, and other orthopedic assessments to determine which areas may need attention.

Extremity Adjustments for the Shoulder

Chiropractic care isn't limited to the spine.

Extremity adjustments can address joints throughout the body, including the shoulder and surrounding structures. When appropriate, a chiropractor may evaluate the AC joint, shoulder complex, scapula, clavicle, and related joints to determine whether restricted or altered joint motion is contributing to the patient's symptoms.

The goal isn't simply to "crack the shoulder." Specific adjustments are performed based on the findings of the examination and the individual patient's needs.

Because the shoulder is a complex system of interconnected joints, improving the motion of one area may help the shoulder function more efficiently as a whole.

Why a Whole-Body Approach Matters

Your shoulder doesn't work by itself.

The shoulder blade, collarbone, upper back, neck, and arm all contribute to normal shoulder movement. That's why a Gonstead chiropractor in Redding, California may evaluate more than just the painful spot.

By assessing the relationship between the spine and extremity joints, chiropractic care can take a more comprehensive approach to musculoskeletal function.

When Should You Have Shoulder Pain Evaluated?

If your shoulder pain began after a fall, collision, sports injury, or other significant trauma—or if you notice a visible deformity, significant swelling, or difficulty moving the arm—it's important to receive an appropriate medical evaluation. More serious AC joint injuries can involve ligament damage and may require treatment beyond chiropractic care.

For persistent or recurring shoulder discomfort, a thorough musculoskeletal examination can help determine what may be contributing to the problem.
