Intersection syndrome
Intersection Syndrome
Intersection syndrome (pronounced: in-ter-sec-tion syn-drome) is a condition that affects the forearm and wrist. It is also known as Cross-over syndrome or Oarsman's wrist.
Etymology
The term "Intersection syndrome" is derived from the anatomical location where the condition occurs. It refers to the intersection of the first and second dorsal compartments of the wrist, where the tendons cross over each other.
Definition
Intersection syndrome is a painful condition characterized by inflammation of the tendons at the point where they cross over each other in the forearm. This intersection occurs about 4 to 8 cm proximal to the radial styloid. The condition is typically caused by overuse or repetitive motion, particularly activities that involve wrist flexion and extension.
Symptoms
The primary symptom of intersection syndrome is pain in the forearm, particularly during movement of the wrist. Other symptoms may include swelling, redness, and a feeling of heat in the area. In some cases, a creaking sensation or sound (crepitus) may be felt or heard when the wrist is moved.
Related Terms
- Tendinitis: Inflammation of a tendon, often caused by overuse or injury.
- Tenosynovitis: Inflammation of the sheath that surrounds a tendon.
- De Quervain's Tenosynovitis: A specific type of tenosynovitis that affects the tendons on the thumb side of the wrist.
Treatment
Treatment for intersection syndrome typically involves rest, ice, and nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce inflammation and pain. In some cases, a splint or brace may be used to immobilize the wrist and allow the tendons to heal. If conservative treatments are not effective, corticosteroid injections or surgery may be considered.
