Sonographische Normalwertbestimmung der Mm. supra- et infraspinatus

Moriggl,B.; Steinlechner,M.; Genser,N.; Sonography has been established as an important adjunct to current diagnostic techniques for the assessment of mammary lymph nodes. Although this method is widely used, no reproducible standard procedure which is equally applicable to the examination of all relevant lymphatic groups has been developed to date. Healthy subjects (n = 50) were examined in an attempt at defining sonographic scanning levels for optimum visualization of anatomic reference landmarks. [Read More]

Subchondrale Mineralisierungsmuster bei Chondromalacia patellae

Eckstein,F.; Müller-Gerbl,M.; Steinlechner,M.; Benedetto,K.P.; The functional adaptation of bone tissue to the mechanical stresses acting on it has been convincingly established. This association should apply as well to the subchondral bone, reflecting the long-term distribution of stress over the joint surfaces. Thirty-six specimens of the human elbow joint were investigated by computed tomography osteoabsorptiometry in order to assess the distribution of the subchondral mineralization. The distal surfaces usually were more highly mineralized than the proximal components of the joint, whereas the humeroulnar and the humeroradial parts exhibited a similar degree of mineralization.
