Intersection Syndrome of the Wrist Causes, Symptoms & Best Physiotherapy Treatment at Physio360.

INTRODUCTION;

Wrist pain is a common complaint among athletes, fitness enthusiasts, office workers, and individuals involved in repetitive hand activities. One lesser-known but significant cause of wrist pain is Intersection Syndrome. If you experience pain, swelling, or a squeaking sensation near the wrist after repetitive movements, this condition could be the reason.

At Physio360 Chennai, we specialise in accurate diagnosis and evidence-based physiotherapy management to ensure fast recovery and long-term relief.

What is Intersection Syndrome?

Intersection Syndrome is an overuse inflammatory condition that occurs where the tendons of the first dorsal compartment (Abductor Pollicis Longus & Extensor Pollicis Brevis) intersect with the tendons of the second dorsal compartment (Extensor Carpi Radialis Longus & Brevis).

Pain Location:

• Dorsal (back) side of the forearm

• Around 4–6 cm above the wrist joint

This condition is commonly mistaken for De Quervain’s Tenosynovitis, but it occurs more proximally.

Causes of Intersection Syndrome

Intersection Syndrome usually develops due to repetitive wrist and thumb movements, especially involving extension and radial deviation.

Common Causes Include:

✔ Repetitive wrist extension

✔ Overuse injuries

✔ Sudden increase in activity intensity

✔ Poor ergonomics

✔ Improper sports techniques

High-Risk Groups

• Badminton & tennis players

• Weightlifters & CrossFit athletes

• Keyboard and mouse users

• Physiotherapists & fitness trainers

• Factory and manual workers

  
  

Symptoms of Intersection Syndrome

Patients visiting Physio360 Centre in Chennai often report:

🔹 Pain in the dorsal wrist and forearm

🔹 Swelling and tenderness over the affected area

🔹 Crepitus (grating or squeaking sensation) during wrist movement

🔹 Pain aggravated by wrist extension and gripping

🔹 Reduced grip strength

🔹 Difficulty performing daily activities

Clinical Diagnosis

Diagnosis is primarily clinical, supported by patient history and physical examination.

Assessment Includes:

✔ Palpation tenderness over the tendon intersection

✔ Pain reproduced with resisted wrist extension

✔ Functional movement assessment

✔ Differential diagnosis to rule out De Quervain’s syndrome

Imaging, such as ultrasound or MRI, may be advised if required.
