Weightlifter’s shoulder, also known as distal clavicular osteolysis, is pain arising from the end of the collarbone. The bone swells and breaks down, causing pain near the acromioclavicular (AC) joint. It’s often confused with other shoulder problems in weightlifters, such as AC joint degeneration or shoulder bursitis. So how do we diagnose and treat weightlifter’s shoulder?
Causes of the weightlifter’s shoulder
Distal clavicular osteolysis results from repetitive overload of the upper shoulder near the AC joint. This overload breaks the bone at the tip of the collarbone (clavicle), causing swelling and pain. We see it most in weightlifters and bodybuilders, but also in athletes who play contact sports or lift heavy weights. Occasionally, it follows a fall onto the shoulder.
How is a weightlifter’s shoulder diagnosed?
A weightlifter’s shoulder is usually diagnosed from the history and examination. The pain is worse during and after exercise, and chest presses and bench presses are the most provocative activities. The tip of the collarbone is typically tender, and people often feel pain when moving the arm across the body.
Shoulder pain from weightlifting has many causes, so it’s essential to rule out others, such as AC joint degeneration, rotator cuff tendonitis, and cartilage (SLAP) tears in the shoulder.
Distal clavicular osteolysis on imaging
Imaging helps confirm the diagnosis. X-rays reveal cysts and erosions at the tip of the collarbone. MRI shows bone swelling at the end of the collarbone and helps exclude other causes.
Is a weightlifter’s shoulder different from AC joint arthritis?
Yes. In a weightlifter’s shoulder, the collarbone swells at its tip due to too much weight training, usually in younger people. AC joint arthritis, by contrast, is wear and tear of the joint, usually in older people. The treatment of the two conditions also differs.
Treatment of a weightlifting shoulder pain
We recommend conservative treatment for almost all cases of distal clavicular osteolysis.
- Rest from heavy weights is essential. Avoid heavy pressing and overhead activities such as chest and shoulder presses — the most provocative being incline bench press, incline press, and heavy dips. You don’t have to stop weight training completely, though: exercises such as decline barbell flyes and machine chest presses are usually less painful.
- Anti-inflammatory measures such as ice and ibuprofen help.
- Physiotherapy restores function and eases you gradually back into heavier chest exercises.
- Patience — allow the collarbone time to heal.
In some cases, a cortisone injection directed at the AC joint and the tip of the collarbone helps.
Surgery is reserved for chronic cases, involving removal of the tip of the collarbone (and any swollen tissue) — now usually via a keyhole approach. Recovery takes up to three months to return to heavy weights, though most people return to light weights after about six weeks.
More about a cortisone injection for a weightlifter’s shoulder
Cortisone is a powerful anti-inflammatory that reduces inflammation and pain. In distal clavicular osteolysis, a cortisone injection reduces inflammation in the collarbone and can speed recovery. The effect usually lasts a few months, occasionally longer — so it’s essential to use that pain-free window to change your training and let the bone heal, rather than rushing back to heavy chest and shoulder work.
We inject under ultrasound guidance to improve accuracy and reduce side effects.
How much does a cortisone injection for a weightlifter’s shoulder cost?
Dr Masci provides a one-stop appointment — consultation, diagnostic ultrasound, and the injection in a single visit. At the Chelsea clinic (the most cost-effective location), a consultation with an ultrasound-guided cortisone injection is £400; other clinic locations cost more. See the full one-stop injection fees here, along with our clinic locations.
Training around the weightlifting shoulder pain
Matt Curley, rehab injury specialist at Complete Physio, says most weightlifting shoulder injuries come from an imbalance between pressing and horizontal pulling. Too much pressing and vertical pulling (pull-ups) creates an imbalance around the shoulder blade, leading to injury.
These imbalances are corrected by stretching the pecs, back muscles, and upper traps. Scapular (“scap”) push-ups improve shoulder-blade movement, and actively controlling the shoulder blade during pressing or pulling improves scapular control. Another key principle is to perform an equal volume of horizontal pulling — single-arm rows, ring rows, and face pulls.
Frequently asked questions about the weightlifting shoulder pain
What is distal clavicular excision?
It’s a surgical procedure that removes the end of the clavicle — the preferred surgical treatment for weightlifter’s shoulder. It generally succeeds, but requires a few months off from heavy upper-body weights. Potential complications include infection and ongoing pain.
What causes AC joint pain with the bench press?
AC joint pain with bench press is usually due to distal clavicular osteolysis (weightlifter’s shoulder). Other causes include rotator cuff tendonitis and AC joint arthritis. Because the treatments differ, it’s worth getting an accurate diagnosis rather than assuming.
How long does a weightlifter’s shoulder take to recover?
With conservative treatment — load modification, anti-inflammatories, and physiotherapy — many cases settle over several weeks to a few months. After surgery, most people return to light weights at about six weeks and heavy weights by around three months.
Can you keep lifting with a weightlifter’s shoulder?
Often yes, with modification. Avoid provocative movements (incline bench press, incline press, heavy dips) and swap in less painful options such as decline flyes and machine press, while you rebalance the shoulder and let the bone settle.
Does a cortisone injection cure a weightlifter’s shoulder?
Not on its own. It reduces inflammation and pain, creating a window to modify your training and allow the collarbone to heal. Returning to heavy pressing too quickly, without changing your programme, tends to bring the pain back.
Final word from Sport Doctor London about weightlifter’s shoulder
Distal clavicular osteolysis is a painful condition in athletes who don’t want to stop training. The good news is that most people get better with relative rest, heavy-weight training, anti-inflammatory measures, and sometimes a cortisone injection. Surgery is a last resort and is usually successful. See a doctor experienced in diagnosing and managing this condition.
