“…Fig. One special pre-erosive sign was described by N o r g a a r d [31] and stated as reliable by Clemmensen [5]. Slight swelling of PIP joint II (RJS =0.24) and PIP joint III (RJS=0.28), punched-out areas of subcortical trabecular loss in the heads of proximal phaianges II and III in a 58-year-oId female with slight arthrosis.…”

Soft tissue radiography of the hands using the mammographic immersion technique was performed on 119 patients, having definite or classical rheumatoid arthritis, and on 123 controls of matching age, sex, and professional distribution. A total of 7744 finger joints and carpal borders were investigated for joint swelling, periarticular edema, pre-erosive and erosive bone changes, joint space narrowing, and osteoarthritic joint margin spurs. Slight joint swelling and pre-erosive bone changes were found in connection with osteoarthritic joint changes in elderly control patients. Periarticular edema and moderate to massive joint swelling were quite reliable signs for synovitis. The incidence of pre-erosive bone signs was significantly greater in the rheumatoid arthritis group than in the control group, especially in patients less than 60 years old. These signs can be regarded as suggestive of rheumatoid arthritis; probability diagnosis could be performed using these signs and the Bayesian approach.

From two population surveys in Sweden and Iceland, hand X-rays of 170 persons between 34 and 70 years of age were read by three sets of observers. Special attention was paid to the features of N9rgaard's sign, namely small erosions at the base of the lateral ends of the phalanges, visible only in the oblique projection, attributable to earIy rheumatoid arthritis. The 1966 criteria for rheumatoid artMtis were applied and two rheumatoid factor tests were wed (AFT and SSCT). Only 16% of the persons were graded identically for X-ray findings by the three sets of observers. In population contexts, N9rgaard's sign was shown to have poor reproducibillty and low specificity and not to contribute significanay to the radiological diagnosis of rheumatoid arthritis. The "overdiaposis" of radiological signs of rheumatoid arthritis made by the radiologists might be due to ethnical difference in the bone structure of the populations examined.

“…Nach Nørgaard [6] und Brewerton [7] können in ihren Schrägprojektionen Erosionen an den Fingergrundgelenken häufiger als in der dv-Projektion gesehen werden. Beim Vergleich der halbschrägen mit den dv-Aufnahmen fanden einige Untersucher mehr Erosionen [8,9,11,12], andere aber keine signifikanten Vorteile zusätzlicher halbschräger Aufnahmen [13,14]. Trotz zusätzlicher Informationen sind die Aufnahmen von Nørgaard [6] und Brewerton [7] für Verlaufsbeobachtungen ungeeignet, da die entsprechende Position bei Verlaufskontrollen nicht sicher reproduzierbar ist und es außerdem zu Überlage-rungen der Mittelhandköpfchen kommt.…”

Conventional radiography is still regarded the gold standard for imaging techniques in rheumatoid arthritis (RA). It is a very important tool for the diagnosis, the differential diagnosis, and the evaluation of the course and prognosis of the disease. Special advantages of conventional radiography are the worldwide availability and experience with the method over decades and the relatively low costs. Moreover, x-rays can be stored and re-evaluated over long periods of time. Joint damage caused by RA can be quantified by means of scoring methods. The amount of destruction correlates well with functional disability over time. The inhibition of damage progression seen on radiographs is the most important characteristic of a DMARD. Typical radiographic changes are part of the ACR classification criteria of RA. Technically, bone structure can be demonstrated with a high local resolution better than with all other imaging techniques, whereas only indirect conclusions can be drawn concerning soft tissue and cartilage lesions. This review includes recommendations given by the "Commission on Imaging Techniques" of the German Society of Rheumatology regarding technical and personal preconditions, costs, indication as well as practical performance of radiography in RA. In addition, radiographic changes that can be expected in RA including destruction and repair are discussed briefly.
