ECU Tendonitis

ECU tendonitis, also known as extensor carpi ulnaris tendonitis, is a condition that involves inflammation and irritation of the extensor carpi ulnaris (ECU) tendon. The ECU tendon is located on the backside of the forearm and runs along the ulnar (pinky side) of the wrist. This tendon is responsible for extending and stabilizing the wrist joint and is crucial for various hand and wrist movements.

ECU tendonitis is commonly caused by repetitive motions that strain or overuse the ECU tendon. Activities that involve repetitive wrist movements, gripping, and lifting heavy objects can contribute to the development of this condition. Additionally, trauma or sudden impact to the wrist can also lead to ECU tendonitis.

Symptoms of ECU tendonitis may include:

• Pain and tenderness on the ulnar side of the wrist and forearm.
• Pain worsens with wrist movement, especially when moving the wrist away from the palm (ulnar deviation).
• Swelling and warmth at the affected site.
• Weakness or discomfort when gripping or lifting objects.
• Crepitus, a grinding or crackling sensation, may be felt during movement.

Diagnosis of ECU tendonitis is typically based on a physical examination, review of medical history, and sometimes imaging tests such as X-rays or MRI scans to rule out other conditions and assess the extent of the inflammation.

Treatment for ECU tendonitis often involves:

• Rest and Activity Modification: Avoiding activities that exacerbate the pain and giving the affected wrist and forearm time to heal.
• Immobilization: Wearing a wrist splint or brace to limit wrist movement and provide support during the healing process.
• Ice: Applying ice to the affected area can help reduce inflammation and alleviate pain.
• Anti-inflammatory Medications: Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) can help manage pain and reduce swelling.
• Physical Therapy: A physical therapist can guide you through exercises to improve wrist strength, flexibility, and overall function.
• Corticosteroid Injections: In cases of severe pain, a healthcare provider may consider corticosteroid injections to reduce inflammation and provide short-term relief.
• Surgery: Surgical intervention is rare but might be considered if conservative treatments do not provide relief. Surgery might involve releasing the ECU tendon or repairing any damage.

It’s important to seek medical attention if you suspect you have ECU tendonitis or are experiencing persistent pain, as early intervention can prevent the condition from worsening and help you return to regular activities with minimal discomfort.
