[Ultrasound image of the lumbar spine and the lumbosacral transition. Ultrasound anatomy and possibilities for ultrasonically-controlled facet joint infiltration].
Is sonography helpful in facet joint infiltration of the lumbar spine? ⋯ This method is a secure and economic (extra time 2-4 min.) alternative to clinically guided infiltration. Flouroscopy guided infiltration is needed only in anatomical variations or if strictly intraarticular application is necessary.

[Use of new biochemical markers in diagnosis of aseptic hip endoprosthesis loosening].
Aseptic loosening of endoprosthesis is the most important problem in total hip arthroplasty. The diagnosis of aseptic loosening is based on anamnesis, the clinical findings, the radiography and scintigraphy. Despite the multitude of diagnostic possibilities it is still a problem to get an exact and early diagnosis. ⋯ All other measured parameters of the bone metabolism showed no significant differences between the both groups. Our results show, that biochemical markers can provide relevant information of endoprosthesic loosening. We are now analysing in a prospective longitudinal study whether these parameters are also suitable to detect early endoprosthetic loosening.
