There is consideration that bilateral carpal tunnel syndrome could be a reason to consider amyloidosis, timely diagnosis of which could improve heart health. [50] Amyloidosis is rare, even among people with carpal tunnel syndrome (0.55% incidence within 10 years of carpal tunnel release). [51]
Anterior interosseous syndrome is a medical condition in which damage to the anterior interosseous nerve (AIN), a distal motor and sensory branch of the median nerve, classically with severe weakness of the pincer movement of the thumb and index finger, and can cause transient pain in the wrist (the terminal, sensory branch of the AIN innervates the bones of the carpal tunnel).
The development of carpal tunnel syndrome was of particular interest for other idiopathic tardy nerve palsies. Carpal tunnel served as a model for how nerves could be squeezed by narrow anatomic compartments and soon other tunnel syndromes were conceptualized, such as cubital tunnel syndrome, and tarsal tunnel syndrome. [87] [88] [83]
[10] Carpal tunnel syndrome (CTS) is caused by compression of the median nerve as it passes under the carpal tunnel. [11] Nerve conduction velocity tests through the hand are used to diagnose CTS. Physical diagnostic tests include the Phalen maneuver or Phalen test and Tinel's sign. To relieve symptoms, patients may describe a motion similar to ...

In the human body, the carpal tunnel or carpal canal is a flattened body cavity on the flexor (palmar/volar) side of the wrist, bounded by the carpal bones and flexor retinaculum. It forms the passageway that transmits the median nerve and the tendons of the extrinsic flexor muscles of the hand from the forearm to the hand . [ 1 ]
The clinical and electrophysiological features of pronator teres syndrome are quite different from patients with carpal tunnel syndrome or pure anterior interosseous syndrome, and are typically normal. [16] [17] Proper localisation is crucial to treatment options. [18] [19]
