Purpose
Wrist is a unique part of a human body,
which is functioning actively in various types of his vital function.
At the same time wrist is the most opened region to injury,
systemic diseases of connective tissues (rheumatoid arthritis),
degenerative processes,
metabolic and neurogenic disturbances [1].
Injuries of wrist and wrist joints account for 25-65% of all damages of musculoskeletal system,
for 1% of population in subpopulation degenerative and inflammatory processes were reported [10].
Injuries and diseases of this region become a cause of development...
Methods and Materials
Cone-beam CT of bones and joints of wrist was conducted on NewTom 5G (QR Verona,
Italy) to 38 patients at the age from 22 to 68 years old.
Patient was in sitting position behind gentry during acquisition time.
Hand was on a special stand in the medium physiological position (Fig.
1,
Fig.
2).
In 84,2 % (n = 32) cases MRI was completed on Centauri MPF 3000 (XinAO MDT,
China),
in 42,1 % (n = 16) cases – MSCT on Brilliance 64 (Philips,
Holland).

Results
Symptoms of degenerative and inflammatory changes of wrist joints were detected in 31 (81,6 %) cases,
consolidated fractures and false joints of bones - in 4 (10,6 %) cases,
fibrous-cicatricial changes of palmar aponeurosis,
tendinitis of the flexor tendons,
ligamentitis were revealed for 3 (7,8 %) patients.
Received cone-beam tomography images of wrists and wrist joints were distinguished by high-resolution,
with a detailed mapping of the bone structure.
Quality of images was comparable in terms of spatial resolution with digital microfocus x-ray and MSCT (Fig....
Conclusion
Clinical testing of CBCT detected the range of possibilities and indications for its use in diagnostics of injuries and diseases of wrists:
- CBCT is a method of choice in assessment of small pathological remodeling areas (under 5,0 mm),
posttraumatic changes of bone tissues,
segments with compound anatomical structure,
where summational effect is marked mostly on standard roentgenograms;
- it gives an opportunity to assess condition of dense soft-tissue structures,
to reveal an accumulation of over fluid in joint cavity,
synovial bursae and tendon vaginas;...
