A flexible correction brace for pectus carinatum, comprising a flexible press plate (1) and a restraining strap (2). The flexible press plate (1) comprises a housing (12) and at least one flexible mechanism. Strap through holes (13) are provided on the housing. The restraining strap (2) runs through the strap through holes (13) to fix the flexible press plate (1) at a protrusion caused by pectus carinatum for extracorporeal correction. When worn, the flexible mechanism (11) is flexibly distended when subjected to an external force, and a dynamic fit relationship is formed between the flexible press plate (1) and the contour of the protrusion caused by pectus carinatum, thus ensuring that the flexible correction brace is allowed to exert continuously an adequate working pressure whilst in motion, preventing insufficient correction pressure due to contraction of the chest cavity, also preventing excessive correction pressure due to expansion of the chest cavity that leads to tissue damages. In addition, because the flexible mechanism (11) can be flexibly distended, regardless of the contour shape of a protrusion caused by pectus carinatum, the flexible press plate can always implement automatic fitting with the contour of the protrusion caused by pectus carinatum.Linvention concerne un appareil orthopédique de correction souple, pour un thorax en carène, qui comporte une plaque de pression souple (1) et une sangle de retenue (2). La plaque de pression souple (1) comporte un boîtier (12) et au moins un mécanisme souple. Des trous traversants de sangle (13) sont formés sur le boîtier. La sangle de retenue (2) sétend à travers les trous traversants de sangle (13) pour fixer la plaque de pression souple (1) au niveau dune saillie formée par un thorax en carène pour une correction extracorporelle.
