Studies evaluating postoperative pain as a risk factor for CPSP are almost exclusively carried out in the context of scheduled surgery. As a result, the preoperative pain studied as a risk factor for chronicity is essentially a state of pain that has persisted for several weeks or even several months.

In emergency surgeries, patients are subject to acute preoperative pain of varying intensity and the duration of which may vary by a few days. A few studies have highlighted the intensity of acute preoperative pain as a factor favouring moderate to severe postoperative pain. At this point, no study has addressed the long-term consequences of this intense preoperative pain the emergency context.

An evaluation in the field of emergency surgery, where the preoperative pain is often intense and limited in time, would enable us to identify more precisely the impact of acute pain on the incidence of CPSP.

The investigators are hypothesising that the occurrence of CPSP at 3 months in patients undergoing emergency orthopaedic or abdominal surgery is associated with acute preoperative pain.
