The carpal tunnel is a small space base of the hand. This tunnel is covered by a thick ligament and creates a small tunnel where various nerves, arteries and tendons pass through from the forearm into the hand.
If anything causes this space to be reduced, these structures can become compressed and damaged, particularly the median nerve. This common condition is referred to as Carpal Tunnel Syndrome (CTS).
The scaphoid is a small bone in the wrist that connects the radius to the hand, and it is situated near the thumb. Scaphoid fractures are a relatively common wrist injury and are commonly misdiagnosed as the pain can be quite mild even when the bone has been broken.
Scaphoid fractures are notorious for their high incidence of complications healing due to low blood supply to the area and how easily their diagnosis can be missed.
