 The anaesthetist in charge of the patient during the pre-anaesthetic visit will complete the data sheet concerning the preoperative status of the patient. He will proceed to the inclusion and provide the data concerning the anaesthetic and analgesic protocol that have been followed. The inclusion will be registered by the local coordinating assistant, who will i send to the patient self-questionnaires 3 and 6 months after the date of surgery about pain, neuropathic symptoms and the resulting quality of life and ii transfer the information to the national coordinating centre Centre for Clinical Investigations of Clermont-Ferrand. A permanent monitoring of inclusions and follow-up will be performed at both local and national levels. This will help to organise the rhythm and the location of inclusions at any time of the study.
