In foot surgery, postoperative edema is a complication making the postoperative outcome quite uncertain as to the rehabilitation of the patient. The evolution of this edema is unknown ... The means of "mastering" this edema are empirical, with little study other than cryotherapy and restraint.

The follow-up will be prospective with measurement of the volume of the foot using an optical technique, during the various follow-up consultations between Day 8 and Month 6 postoperative.
