  • described as a mononeuropathy or radiculopathy, it is caused by tight packing of tendons and the median nerve in the carpal tunnel such that any swelling is likely to cause ischaemia and compression of the nerve
  • most commonly diagnosed compression neuropathy of the upper limb (1,2)
  • more common in females than in males
  • peak age ranges from 40 to 60 years
