Carpal tunnel is an anatomical compartment in the wrist, which includes the median nerve and flexor tendons inside, surrounded by the carpal bones
scaphoid, trapezium, and hamatum that form an arch.
The multiple dorsal and volar extrinsic ligaments are low-signal bands overlying the carpal bones
and intrinsic ligaments.
Designed to reduce the risk of soft tissue irritation associated with traditional wrist fusion plates, Acumed's new Total Wrist Fusion Plating System, fuses the carpal bones
together to treat post-traumatic arthritis.
showed delayed ossification and irregular margins.
The trapezoid is infrequently injured due its position within the wrist, situated within strong intercarpal ligaments and between the base of the second metacarpal and carpal bones
(Afifi and Lu, 2011).
The carpal bones
are rotated, which puts increased stress on the ring finger, which along with the long finger is most often involved in injury.
In this case, not only scaphoid fracture and rupture of scapholunate ligaments were seen, but also excessive displacement due to severity of trauma resulted in carpal bones
free of any ligamentous attachment.
Only a true lateral view will show the dorsal displacement of the metacarpals relative to the carpal bones
The presence of bone erosion was evaluated in 15 different regions (8 carpal bones
, 5 metacarpal heads, 1 distal radius, and 1 distal ulna).
Interosseous ligaments refer to ligaments connecting carpal bones
, whereas extraosseous ligaments connect the ulna and radius to the carpal bones
The back wall of the carpal tunnel is bound by the carpal bones
and a band of strong tissue called transverse carpal ligament.
Magnetic resonance imaging of the right hand showed numerous sclerotic lesions in the distal radius, ulna, carpal bones
and metacarpal head.
