[CT study of the carpal tunnel. Normal anatomy].
The standard technique for CT investigation of the carpal tunnel and its normal anatomy were studied. Ten healthy asymptomatic volunteers, age 25-45, underwent wrist CT. The hand is placed in prone position with the third metacarpus in line with the radius. Digital radiograph and four axial CT scans are performed respectively: at the distal end of the radius, at the scaphoid tubercle level, at the hamate hook level and at the carpal-metacarpal joint. Standard carpal tunnel diameters are thus available with good reliability and repeatability when correct technique is adopted. The results permit a morphological description of the osseous walls, transverse ligament, flexor tendons with synovial sheets and median nerve. Gujon's canal and its content can also be investigated.
