Extensor digiti minimi muscular flap: From a clinical case to an anatomical study.

We present a case report of a failed posterior interosseous flap with distal pedicle rescued by an extensor digiti minimi (EDM) island pedicle flap supplied by the posterior interosseous artery (PIOA) in reverse flow to cover a soft tissue defect in the hand of a 25-year-old man. We subsequently performed an anatomical study on 5 cadaver limbs to determine the EDM muscle's vascularization: it was segmental, multiple and came from the PIOA. The rotation arc reached the dorsal side of the metacarpophalangeal (MCP) joints, as well as the distal part of the thumb.

[The unsightly chest: Analysis and anomaly. Curative or palliative approach?].

Anterior chest wall deformity are mostly represented by pectus excavatum, which is a depression of the chondrosternal plastron from the 3rd to the 7th pairs of the costal cartilages, then by pectus carinatum which conversely represents a protrusion of this plastron. The major esthetic and psychosocial impact is not to be demonstrated anymore whereas the cardiopulmonary functional impact remains still highly debated. Regarding the management, curative surgical techniques such as Wurtz's sub-perichondrial simplified sternochondroplasty or Nuss' minimaly invasive technique are opposed to palliative filling technique such as customized silicone implant, lipostructure and flaps.
