The role of the bone scintigraphy in 3 phases in knee algodystrophy

Full text: The neuro-algodystrophy appears, classically, as a syndrome of diffuse pain in a member, frequently with a burn symptom and as a consequence of a noxious impulse or lesion, without major nervous attaining and associated to variable trophic, autonomic, motor and sensitive alterations. The authors present 3 cases of neuro-algodystrophy after surgery of the anterior crossed ligament, detected 3 to 10 months later, during the evolution period. They intend to detach the following points: scarce in the literature on the neuro-algodystrophy after-surgery of the anterior crossed ligament; diagnosis difficulty by frequent lack of major clinic criterion on this pathology. The objective of this work is demonstrate the image acuity and the importance of the bone scintigraphy in 3 phases with technetium-99m MDP (methylenediphosphonate) in the ratification of the clinic suspect of neuro-algodystrophy of the knee and in the control of the disease evolution and therapy efficiency, as well. Conclusions: Relevant role of the bone scintigraphy in 3 phases with technetium-99m MDP (methylene diphosphonate) in the neuro-algodystrophy diagnosis and follow-up and importance of a therapeutic program suitability
