[Value of punch and puncture drill biopsy in the diagnosis of tuberculous spondylitis].

Thanks to a specially designed guide instrumentarium, punch and drill aspiration biopsy for the vertebrae and intervertebral spaces have become routine diagnostic procedures which any patient can be expected to tolerate. With the authors' puncture technique material can be obtained from a single vertebra at various heights or simultaneously from different segments with the drilling cannula. For an experienced osteopathologist histologic assessment of the tissue cylinders obtained or of aspirated material presents no problems. Percutaneous removal of samples by this method avoids an open diagnostic intervention with its considerably greater attendant risks, or enables a therapeutic intervention to be prepared with greater precision. The authors report on their own experience of drill aspiration biopsy in 35 fully documented patients and discuss considerations regarding indication and confirmation of the diagnosis.

[Occurrence of pannus in arthrosis].

Eight human femoral heads, surgically removed from patients with the clinical diagnosis: coxarthrosis or necrosis, were examined. In six of these we found severe arthrosis combined with synovitis and pannus formation. The pannus appeared as granulation tissue or fibrous connective tissue covering the surface of the cartilage or growing into it. In most cases the pannus showed a destructive appearance, although newly formed cartilage repair tissue was also observed. There was no indication for a pannus originating from the bone marrow. We therefore assume that we are dealing with a pannus of synovial origin. The possibility of a local transformation of chondrocytes into fibroblasts, is also discussed. The earlier reports concerning the occurrence of arthrosis in combination with pannus, are contradictory. We suggest that coxarthrosis can occur both with and without pannus. These two possibilities may represent different forms of arthrosis.
