Intersection Syndrome in a Handcyclist: Case Report and Literature Review

Intersection syndrome is a rare inflammatory condition located where the first dorsal compartment muscles and the radial wrist extensor muscles cross. It's caused by repetitive wrist movements and overuse. The condition is an overuse injury that results in pain, swelling, and sometimes crepitus (a crackling sensation) in the forearm, typically about 2 inches proximal to the wrist. Treatment includes rest, splinting the wrist, and using anti-inflammatory medications like naproxen. In some cases, corticosteroid injections or surgery may be considered.

• 1
  A handcyclist with a spinal cord injury developed intersection syndrome after a long training session involving repetitive wrist flexion and extension.
• 2
  The patient's symptoms improved with a wrist splint, naproxen, and modification of handcycling technique to avoid wrist flexion and extension.
• 3
  The patient was able to return to handcycling, including completing marathons, after the injury with modified techniques and without recurrence of symptoms.
