MR-Tomographie bei Innenbandverletzungen des Kniegelenkes
1992
Frequency and characteristics of lesions of the medial collateral ligaments (MCL) were studied by MRI in 155 patients with trauma to the knee. There were abnormalities of the MCL in 38% of cases with ligamentous injuries and in 27% these were combined with meniscal tears. 11% of these patients showed isolated rupture of MCL and as a result of the MRI findings were treated conservatively. By means of T2*-weighted images the individual lesions could be accurately localised. Characteristic findings have been defined.

Messung der Pfannenwanderung bei zementfreien Hüftimplantaten
1998
PURPOSE Migration measurements of acetabular components using a special computer aided method (EBRA = abbreviation for the German term "Ein-Bild-Rontgenanalyse") were performed to evaluate early results of the implants and predict aseptic loosening. METHODS Standard ap-radiographs of the pelvis were marked, specific points were digitised. Simulating the spatial situation the programme computes longitudinal and vertical migration of the cup. 74 acetabular components in 71 patients could be studied by migration measurements. RESULTS 14 patients showed migration of more than 1 mm, which is the confidence limit of this method. Each of these patients showed diverse reasons for the migration, i.e…
The pathophysiology of aging bone jaw: primary and secondary prevention
2010
The skeleton is composed of approximately 200 bones, and it is the backbone of our body along with ligaments and joints. The bone is not a static but a dynamic structure, constantly reshuffling, that may suffer fractures due to trauma, despite their particular hardness and strength. Complex physiologic mechanisms, sometimes with the help of surgery, can lead to bone repairing. In the elderly, often, the skeletal system can be affected by osteoporosis, a "silent disease" that causes fragile bones especially of the vertebrae and femur; its contributing factors are menopause (in women), smoking, nutritional deficiencies, systemic diseases or prolonged use of drugs. The masticatory apparatus an…
Skelettveränderungen bei Frühgeborenen mit Kupfermangel
1991
We describe 5 preterm infants (25th to 30th week of gestation) suffering from alimentary copper deficiency. The diagnosis was confirmed by low serum copper and caeruloplasmin concentrations. Characteristic clinical findings were repeated apnoeic attacks, hypopigmentation of skin and hair, anaemia, neutropenia and leucopenia refractory to other therapy, as well as increasing serum alkaline phosphatase activity in the first month of life. Starting in the 3rd to 12th week of life the radiographic findings were general skeletal osteoporosis and retardation, metaphyseal radiodense lines, irregular metaphyses, cupping and spurring of the metaphyses, followed by multiple fractures and subperiostea…
Bildgebende Diagnostik der Peritonealkarzinose
1990
Two hundred and eighty-seven radiological and sonographic examinations in 142 patients with confirmed peritoneal carcinosis were evaluated retrospectively. The examinations included abdominal films (19), infusion urograms (20), contrast examinations of the intestine (26), small bowel enemas (2), double-contrast examinations of the colon (40), demonstrations with water-soluble contrast (6), sonographies (80) and CTs (96). CT and colonic double-contrast studies were complementary and valuable methods for diagnosing peritoneal carcinosis and should both be used.
