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.
3).
A decisive importance in assessment of form,
contours and structure of bones in traumatology and orthopedics in planning and control of results of treatment of extremity’s injuries and diseases is minimum artifacts from the metal structures or foreign bodies with metal density was a prime advantage of CBCT to MSCT (Fig.
4).
In addition,
accurate differentiation of bone trabeculae and minor structure changes,
bone fractures and defects,
which size was no more than 3-5 mm,
were observed on CBCT-images.
These changes were also well rendered on MSCT-images and on digital microfocus roentgenograms,
but were not defined reliably in the standard x-ray (Fig.
5).
CBCT gives a possibility to assess condition of dense soft-tissue structures: capsular-ligamentous apparatus,
tendons and fasciae,
to reveal an accumulation of over fluid in joint cavity (synovitis and tendovaginitis) (Fig.
6).
