[Regional blood circulation in the area of the hip joint in patients with various inflammatory rheumatic diseases].

An analysis of the results of a study of the regional blood circulation in 36 patients with marked pathology of the hip joints of inflammatory nature (rheumatoid arthritis, Bechterew's disease, Reiter's disease) showed a statistically significant increase in transcutaneous oxygen pressure in the projection of the affected joints in unilateral as well as in bilateral pathology. In unilateral pathology there was a significant increase in transcutaneous oxygen pressure, on the surface of the contralateral joint, where pathology was undetectable by routine clinical methods. In the authors' opinion, it could be indicative either of an early stage of the joint involvement or the general reaction of a region under study to an inflammatory process.
