[Spinal stiffness. Differential imaging diagnosis with reference to acquired hyperostosis syndrome and spinal loading disease].

There are numerous diseases which can irreversibly stiffen the whole spine or parts of the axial skeleton. Due to didactic reasons one can distinguish 3 groups of such disorders: Paradigmatic diseases of the spine with an inherent proneness to stiffness. Rare diseases which involve a certain danger of stiffening the spine.

Dense bone around the sacroiliac joint: a radiological review of the differential diagnosis.

Solitary osteosclerotic bone lesions around the sacroiliac (SI) joints are described as seen on plain radiographs or conventional tomography, with the descriptive attributes ranging from round to ovoid over square and triangular to multiform. The etiology of the solitary osteosclerotic lesions around the SI joint can often be concluded from the radiographic appearance, sometimes complemented by the presentation on CT and/or scintigraphy.

[Osteoclastic finger arthrosis--a subtype of hand polyarthrosis].

Aim: Description of a subtype of arthrosis deformans of the hand which is characterised as osteoclastic arthrosis.

Patients And Methods: Retrospective analysis of radiographs of the hands of 150 women and 100 men with radiological findings of arthrosis deformans.

Results: 5% of women and 2% of men showed at least one digital joint with subchondral osteolysis of one or both articulating bones involving at least a third of the phalanx.

Acquired hyperostosis syndrome--AHYS--(sternocostoclavicular hyperostosis, pustulotic arthro-osteitis, SAPHO-syndrome): bone scintigraphy of the anterior chest wall.

The objective of this report is to provide a description of diagnostically significant scintigraphically recognizable sites and patterns of acquired hyperostosis syndrome (AHYS) on the anterior chest wall (ACW), which is involved in 82% of AHYS patients. In 49/90 of our own AHYS patients, planar bone scans of the ACW were performed with the gamma camera, applying an average of 650 MBq of 99mTc-phosphate complexes. In addition, 53 atraumatic patients with extrathoracic cancer were available for routine whole-body scintigraphy.

[Comparative roentgenometry of the hand in aging].

Increasing age is a risk factor for the development of osteoarthrosis of the joints of the hand in adults between 21 and 60 years of age. Only in the very old (> or = 80 years) is osteoarthrosis of the hand part of the age related degeneration. The literature contains different parameters and indices correlating the amounts of minerals and ashes of metacarpal bones.

[Technique and economics of first worldwide roentgen conference via public phone lines with the Medical Desktop-Conference and Integrated Services Digital Network].

The introduction of the world's first Medical Desktop-Conference via public phone lines (ISDN-S2M) in spring 1994 for the weekly discussion of radiological findings with 25 orthopedic surgeons has proved the effectiveness of this system developed by the project BERMED. The use of standard hard- and software as well as ISDN are the most important factors to keep the system costs low. Technical advantages can be seen in the immediate, loss-free transmission of image and other patient-related data and in the integration of digital archives.

The supercilium acetabuli score: an additional criterion for estimating the biomechanics of the hip joint.

There are significant correlations between the surface of the acetabular roof sclerosis (supercilium acetabuli) in the hip joint on a normal a.p. radiograph and the corresponding surface of cartilage.

[Side effects and efficiency of 15 mg and 25 mg methotrexate per week in chronic polyarthritis].

To examine the rate of side effects and the dose dependence of side effects 185 consecutive patients with active rheumatoid arthritis were randomized to receive 15 mg (group A) or 25 mg (group B) methotrexate (MTX) per week and studied prospectively over 12 months. Dose adjustments were performed according to tolerability and efficacy. With 168 patients eligible for evaluation the rate of withdrawal for any reason was 26% in group A and 27% in B.

The acquired hyperostosis syndrome: a little known skeletal disorder with distinctive radiological and clinical features.

The acquired hyperostosis syndrome (AHS) is a chronic inflammatory disorder of bone of unknown etiology. It is accompanied by circumscribed hyperostosis which can be associated with ossifying lesions at sites of tendinous and ligamentary insertions and erosive or non-erosive arthritis. The predominant location of lesions is the sternocostoclavicular region (approximately 80% of patients), less frequent are involvement of the spine, pelvis, and appendicular skeleton.

[Acquired hyperostosis syndrome (so-called pustular arthro-osteitis). Review of the literature including 73 personal cases].

The acquired hyperostosis syndrome (AHS) (best known synonym: pustulotic arthro-osteitis) is a system disease of the supporting and gliding tissue with sites of predilection characterized by inflammation-induced bony reconstruction of positive balance. This syndrome is affiliated with the seronegative spondylarthropathies. The main finding is the sternocostoclavicular hyperostosis in about 80% of patients.

[Adhesive (retractile) capsulitis of the hip joint in diabetes mellitus. An x-ray histomorphological synopsis].

Adhesive (retractile) capsulitis of the hip joint is a rare complication (association) of (juvenile) diabetes mellitus. The clinical features, plain radiographic and CT findings and histomorphological appearances of this condition are described and attention is drawn to changes in the elastic tissue in the fibrosed capsule. Three diagnostic radiological features have been defined; in their presence, arthrography or diagnostic arthroscopy need not be performed.

[Pelvic roentgenometry of the third kind: age- and sex-related measurement results in adulthood].

Normal values in adults for the hip joint (3.5-6 mm), the sacro-iliac joint (1-3.5 mm) and the symphysis (up to 7.

[Pericoxal fat stripes and the capsule of the hip joint. The anatomical-radiological correlations].

The capsule of the hip joint can always be demonstrated on antero-posterior radiographs provided two conditions are met: 1. the so-called gluteus minimus fat stripe is shown and 2. the exposure is made in maximal external rotation which can be either active or, better still, passive.

[Alloarthroplasty of the hip joint. Radiologic diagnosis of loosening and infection in cemented total endoprostheses].

Patients with problems following implantation of cemented total hip prostheses must be clinically examined. This examination is followed by a series of diagnostic imaging procedures. These include X-ray diagnosis, 3-phase 99mTc-MDP bone scans, scintigraphy for inflammation, and arthrography, performed singly or as sequential studies.

Acquired hyperostosis syndrome: spectrum of manifestations at the sternocostoclavicular region. Radiologic evaluation of 34 cases.

Thirty-four patients with chest wall hyperostosis, a condition which has been designated by various terms in the literature were evaluated radiologically. We prefer the name acquired hyperostosis syndrome (AHS), which we categorize into the complete, incomplete and possible form. In complete AHS, sternocostoclavicular hyperostosis is associated with axial and/or peripheral (endosteal, periosteal, enthesopathic, metaplastic) hyperostosis and with psoriasiform or acneform dermatosis.

[Supercilium acetabuli. A stress indicator of the hip joint cartilage].

A thousand radiographs of the hip joints in adults were evaluated quantitatively and the following statistical conclusions were drawn: the normal forms of the supercilium acetabuli are either parallel or convex. Wedge-shaped supercilia indicate increased stress on the cartilage only in cases with hip dysplasia. A supercilium of more than 4mm raises the suspicion of increased stress on the cartilage.
