[Scintigraphic examinations of sacroiliacal joints in patients with early forms of ankylosing spondylitis].

In contrast to the X-ray examination the scintigraphy of the sacroiliacal joints in the early phase of the ankylosing spondylarthritis allows an evidence to the local processes of bone reconstruction directly depending on their activity. Positive findings of scintigraphy have a high sensitivity and a low specifity. They demand a further differential-diagnostic clarification. In this sense, supplementing the X-ray findings, the scintigraphy brings valuable informations for the early diagnostics of ankylosing spondylarthritis. The radiation exposure of the gonads which is smaller by factor 3 in comparison to the X-ray examination of the pelvis is an essential advantage in the above all young patients. The valuation of the scintigramme must be performed in close connection between clinical rheumatologists and specialists in nuclear medicine. Our results show that longitudinal examinations let expect a further improvement of the evidence.

[Is unicondylar knee prosthesis a current possibility in primary management of varus gonarthrosis?--A prospective matched-pair study].

AIM: In the present study, we performed a follow-up investigation comparing middle-term results after unicompartmental and bicompartmental knee arthroplasties. MATERIAL AND METHODS: We used matched pairs with 18 patients in each group. The first group was treated with the unicompartmental slegde prosthesis (Type Wessinghage), the second with the cementless nonconstrained bicondylar prosthesis (Type Natural knee). The mean time of follow-up was 4.5 years. (SD +/- 0.6). The average age of the patients in both groups was 59 years (SD +/- 3). Both groups included 12 female and 8 male patients. All patients suffered from primary medial osteoarthritis of the knee. In all cases, the contralateral knee also had signs of manifest osteoarthritis. The determination and evaluation of the results of the investigation were made according to the score of the American Knee Society. We also reviewed the radiological findings concerning placement of the prosthesis, radiolucent lines, and patella position in the femoral shield. RESULTS: At follow-up examination, there were no significant differences in the knee score between the patients undergoing unicompartmental or total knee replacement. However, patients with the Wessinghage sledge tended to show better results. The mean knee score was 94.3 +/- 4.9 in the Wessinghage group and 91.9 +/- 8.3 in the Natural knee group. Evaluation of the radiographs revealed radiolucent lines in the group with total replacement. In contrast, in 7 of 18 patients with the unicompartmental prostheses we found radiolucent lines at the tibial component of 1 mm or more, which, however, did not cause clinical symptoms. CONCLUSION: Our results show, that the unicompartmental arthroplasty is still an effective method for the treatment of the osteoarthritis, especially concerning the conditions for possibly needed revisions.
