[Morphological diagnosis of spinal diseases. Current technical possibilities and challenges for the histological preparation of transpedicular biopsies].
The spine is the central component for the mobility of the human body. Both locally limited and diffuse pathologies of the spine are a challenge for the treating physician due to the difficult anatomy. The biopsy of a pathologically altered vertebral body is a fast and reliable basis for further therapy but until now this has not regularly been made use of as a diagnostic standard for spinal diseases, since the tissue gained was often microfractured because of the difficult anatomical position. Our own experience with transpedicular vertebral biopsies of 70 patients with different diseases is reported because of the considerable improvement in the biopsy technique and the methodical possibilities for processing the bony tissue. Methods which have proven particularly valuable are contact radiographs, embedding in plastic, careful decalcifying with EDTA and immunohistological procedures. In this way a definite diagnosis can be made in 97% of the cases. A close cooperation with the clinician carrying out the biopsy and a greater use of methods other than just fast decalcification is recommended.
