92 data will be collected during the patient care episode. Among the 92 criteria, 63 are pre-operative, 29 are post-operative in order to provide an evolutionary prediction during the management of the patient.

Post-operative follow-up criteria making it possible to establish the scalability or non-scalability of the quality of life after the surgical procedure.

The results will be compared to the prediction proposed by the machine learning algorithm.

The current study is interventional insofar as the patient is collecting all of his socio-medical information. The analysis of the data provided by the patient makes it possible to establish a long-term prognosis for the patient but does not in itself constitute a parallel medical approach.

SUMO allows the surgeon to transmit post-operative advice developed by the surgeons themselves.

Establishment and prospective evaluation of a predictive tool with the area under the receiver operating characteristic (AUROC) metric >= 80% Sensitivity >= 90% Specificity >= 60% in the capacity of providing for each back operated patient a clinical predictive status: green patient (success) orange (treatment failure), red patient (complication).

Implementation, optimization and evaluation of a digital tool for collecting patient data on the episode of care
