Post-traumatic Perthes syndrome in adults is a rare manifestation. It poses a management problem and treatment is based on aggressive and directed management of the cardiopulmonary systems associated with rapid recognition and treatment of progressive lesions. The result differs depending on the duration, mechanism and severity of the compression, which justifies extreme caution in the approach to these patients. We report the observation of a rare case in a patient, with a history of DALY under treatment and hypertension poorly monitored under treatment, admitted to intensive care for Perthes syndrome resulting from serious thoraco-abdominal trauma following to a fall from a crane and whose clinical evolution was satisfactory. The objective is to emphasize the beneficial effects of early treatment of this rare syndrome in adults.
