Bone Circulation and Bone Necrosis: Proceedings of the Ivth International Symposium on Bone Circulation, Toulouse (France), 17th-19th September 1987

The topic of bone circulation is relatively new and has developed very quickly in the past 20 years; this book reports on the most recent progress since 1982. The chapters discuss the anatomy of bone vascularization, the physiology of vascular regulation, the histopathology of microcirculation and osteonecrosis, experimental studies on bone-blood flow, experimental surgery, methods of exploration, vascular studies of grafts and bone transfer, and surgical and conservative treatment. New developments are given on blood-bone barrier, effect of PGE2 on blood-bone flow, laser Doppler flowmetry, microcirculation and demineralization, vascular repair in osteotomy and fracture, bone arteriography, angioscintigraphy, Ilizarov's technique, and therapeutic aspects of lipid-clearing agents.

th This book contains most of the papers presented at the Iy Inter- national Symposium on Bone Circulation which was held in Tou- louse, France, in September of1987. The symposium was attended by over 200 specialists from 17 different countries. Some of them were in Toulouse for the fourth time to discuss their favourite topic of study and research: bone circulation, its exploration, its pathol- ogy. Many, including a group of Japanese orthopaedic surgeons, were present for the first time, delighted to meet the authors of papers they had read. There were more than 100 oral presentations and posters, but many meaningful informal discussions took place both in and outside of the auditorium, in the hall and during meals. The organizers wished to maintain a balance between funda- mental themes and subjects of clinical and practical interest. This balance was accomplished: recent developments including scintig- raphy, magnetic resonance imaging and bone grafts played just as important a part as more sophisticated topics such as the evalua- tion of the blood flow rate in animal bone tissue. Thus, as did the previous symposia, this book aims to present a progress report on developments during the last 5 years in the study of bone circulation. We wish to thank all those who helped and encouraged us throughout the organization of the congress, especially C. Ar- noldi, M. Brookes, R. Burkhardt, L. Coutelier, S.P.F. Hughes, P. Kehr, J.P. Jones, A. Trias, K.Ono, T. Yizkelety and G.J.

This book reports the progress made since 1982 in this new topic of bone ciruclation and the problems and diseases which arise when it is impaired.
