Recognising the Symptoms and Signs
Ali Phillips | Hand & Wrist Specialist
Pain in your forearm near the back of your wrist?
I'm Ali Phillips. If you're feeling pain and tenderness on the middle of the back of your forearm, a few inches from your wrist, you might have Intersection Syndrome. Let's explore this overuse condition and how we can get you back to your activities without pain.
Book a ConsultationWhat is Intersection Syndrome?
Intersection Syndrome is an overuse condition affecting the tendons in your forearm. It occurs at the specific point where two sets of tendons cross over each other. Imagine two ropes rubbing together – this friction causes the tendon linings (the tenosynovium) to become inflamed and swollen.
This condition is common in people who do activities involving repetitive wrist extension, like rowers, weightlifters, and racquet sport players. The pain is located a few inches up from your wrist on the thumb side of your forearm.
What are the symptoms of Intersection Syndrome?
Localised Pain
Pain and tenderness on the top of the forearm, about 4-6 inches up from the wrist joint.
Swelling
You might notice a visible swelling in the painful area due to the inflammation of the tendons.
Squeaking Sound (Crepitus)
Sometimes, you can hear or feel a "squeaking" or "creaking" sound as the inflamed tendons rub against each other.
Is This Your Forearm Pain?
If this specific pain and swelling is stopping you from enjoying your activities, a clear diagnosis is the first step towards a solution. Let's find out what's going on and create a plan to help.
Get a Clear DiagnosisHow will I diagnose your forearm pain?
Diagnosis is primarily based on a physical examination. The location of the pain and the presence of crepitus (the squeaking sound) are key indicators. You can try a simple self-test at home, but stop if it causes significant pain.
1️⃣
Rest your forearm on a table.
2️⃣
With your other hand, place your fingers gently over the painful area on your forearm.
3️⃣
Repeatedly bend your wrist up and down.
If you feel a creaking or squeaking sensation under your fingers during this movement, it is a very strong sign of Intersection Syndrome. An ultrasound scan can also be used to confirm the inflammation.
How can I help you get better?
We'll create a personalised treatment plan together, always starting with the simplest options first.
Rest & Splinting The most important first step is to rest the arm and avoid the activities that cause pain. A splint can help to immobilise the wrist and allow the inflammation to settle.
Anti-inflammatories Over-the-counter medications like ibuprofen can help to manage pain and reduce inflammation.
Steroid Injections An injection of corticosteroid directly into the inflamed area can be very effective at settling the inflammation and providing lasting relief.
Surgery Surgery is rarely needed but can be considered if other treatments fail. The procedure involves a small incision to release the tight compartment, allowing the tendons to glide freely.
Frequently Asked Questions
They are both tendon inflammation problems, but they occur in different locations. De Quervain's causes pain directly at the base of the thumb on the side of the wrist. Intersection Syndrome causes pain higher up the forearm, about 4-6 inches from the wrist, on the top surface.
With complete rest and by stopping the activity that caused it, mild cases can sometimes resolve. However, because it's an inflammatory condition caused by friction, it often requires treatment to fully settle down and prevent it from becoming a chronic issue.
The medical term is "crepitus." It's a very distinctive sign of Intersection Syndrome and is caused by the inflamed and swollen tendon linings rubbing against each other as they cross over. It can sometimes sound like wet leather rubbing together.
A steroid injection is often very effective for Intersection Syndrome. Because it's a problem of inflammation in a specific area, delivering a powerful anti-inflammatory medication directly to the source can provide significant and often long-lasting relief.
Surgery is rarely needed for this condition. It would only be considered in persistent cases where non-surgical treatments like rest, splinting, and injections have not provided adequate relief from the pain.
