The reorganization of the department and the principal investigator's retirement halted patient enrollment in this study. Only 4 patients were enrolled, which made it impossible to meet the primary objective.

The definitive treatment of disabling metatarsalgia requires surgery. In recent years, a percutaneous technique has been developed, the "Distal Metatarsal Mini-invasive Osteotomy" (DMMO). It consists of performing extra-articular osteotomies that are not osteosynthesized and maintained during the time of bone consolidation by a dressing and specific offloading footwear.The patient is encouraged to resume walking immediately after the procedure, as full plantar support is an integral part of the surgical concept. The goal is to actively modify the distribution of all metatarsal supports by the pressure exerted on the ground during walking and by tendon tensions, in order to reduce forefoot deformities.

DMMO offers many advantages over traditional techniques, but it remains a painful forefoot surgery in the short term despite the systematic use of analgesics and the wearing of a dedicated therapeutic shoe.

The study will seek to identify the predictive character of podobarometric parameters at walking (D+7 and D+30 post-op), between patients who will require a palliative solution versus those who will not (D+90)
