Rotation cryotomy: medical and scientific value of a new serial sectioning procedure

Kathrein,A.; Klestil,T.; Birbamer,G.; Buchberger,W.; Rabl,W.; Kuenzel,K.; Preparation of thin serial sections for comparative macromorphologic investigations has always represented a grave technical problem, especially in the case of regions in which bone as well as soft tissue are to be documented within their natural relations to each other in any desired sectional plane. Non-decalcified specimens up to the size of a whole cadaver are embedded in physiologic medium, precisely positioned, and deep-frozen to a specimen-ice block. [Read More]

Serious complications from active compression-decompression cardiopulmonary resuscitation

Rabl,W.; Baubin,M.; Broinger,G.; Scheithauer,R.; Complications arising from techniques of cardiopulmonary resuscitation (CPR) were reviewed by analysing the autopsy protocols of 25 patients who died after standard (Std) CPR and 31 who died after active compression-decompression (ACD) CPR, 15 of them preceded by Std CPR. The results can be summarised as follows: After Std CPR (n = 25) rib fractures were detected in 28%, sternal fractures in 16%, and no injuries in 68%. [Read More]

The contribution of anulus fibers to torque resistance

Krismer,M.; Haid,C.; Rabl,W.; STUDY DESIGN: Anulus fibers of the intervertebral disc oriented in one direction were dissected, and oppositely directed fibers were left intact as a result of a newly developed dissection method. Motion segments were dissected by this way, and motion segments after bilateral facetectomy were loaded in torsion and compared with each other. OBJECTIVES: To assess the contribution of facets and anulus fibers to torque resistance. SUMMARY OF BACKGROUND DATA: Mathematical models predict that torsional stress is transmitted only to those collagene fibers of the anulus that are angled in the direction of the applied torque.
