The results of 480 computed tomograms carried out in the hand are presented. The digital slice imaging technique shows following advantages: a) Imaging of the complex carpus without superimposition giving a better understanding of carpal biomechanics. b) Anatomically exact imaging of the soft tissues determined by density analysis. In the following states relevant information can be obtained by CT of the hand: 1. Posttraumatic states of the carpus such as scaphoid non-union, lunato-malacia in stages I and II, complex fracture dislocations, and carpal instabilities; 2. cystic transformation of the bone; 3. non-idiopathic CTS; 4. clinically unequivocal soft-tissue masses. In our institution conventional tomography has been largely replaced by carpal CT within a progressive diagnostic programme. Today CT is the best method for imaging soft-tissue masses of the hand.

D011542 Pseudarthrosis A pathologic entity characterized by deossification of a weight-bearing long bone, followed by bending and pathologic fracture, with inability to form normal BONY CALLUS leading to existence of the "false joint" that gives the condition its name.

D002348 Carpal Bones The eight bones of the wrist: SCAPHOID BONE; LUNATE BONE; TRIQUETRUM BONE; PISIFORM BONE; TRAPEZIUM BONE; TRAPEZOID BONE; CAPITATE BONE; and HAMATE BONE. Bone, Carpal,Bones, Carpal,Carpal Bone
D002349 Carpal Tunnel Syndrome Entrapment of the MEDIAN NERVE in the carpal tunnel, which is formed by the flexor retinaculum and the CARPAL BONES. This syndrome may be associated with repetitive occupational trauma (CUMULATIVE TRAUMA DISORDERS); wrist injuries; AMYLOID NEUROPATHIES; rheumatoid arthritis (see ARTHRITIS, RHEUMATOID); ACROMEGALY; PREGNANCY; and other conditions. Symptoms include burning pain and paresthesias involving the ventral surface of the hand and fingers which may radiate proximally. Impairment of sensation in the distribution of the median nerve and thenar muscle atrophy may occur.
