Disclosed is an intraosseous pressure release nail, comprising a nail rod (100) with a central cavity (110) disposed therein and a nail cap (200) rotatably disposed on one end of the nail rod (100). A pressure release part, which communicates the central cavity (110) with the outside, is disposed on the nail cap (200). A rinsing opening (120) is disposed on the rod section of the nail rod (100) which is located within the nail cap (200), and the rinsing opening (120) is in communication with the central cavity (110). The lateral wall of the nail cap (200) is disposed with an open/close opening (210), and the open/close opening (210) can rotate with the nail cap (200) to a state in which it is in communication with the rinsing opening (120). By providing a nail cap (200) with a pressure release part at the end of the nail rod (100), during treatment, blockage of the patient with the nail rod (100) during the course of feeding can be prevented, ensuring the patency of pressure release. When bones need to be rinsed, the nail cap (200) is rotated to a position in which the open/close opening and the rinsing opening are in communication with each other, so that rinsing can be carried out by adding rinsing liquid to the central cavity via the rinsing opening, thus improving the therapeutic effect of core decompression surgery.Linvention concerne un clou de libération de pression intra-osseuse, comprenant une tige de clou (100) ayant une cavité centrale (110) disposée à lintérieur de cette dernière et un couvre clou (200) disposé de façon rotative sur une extrémité de la tige de clou (100). Une partie de libération de pression, qui fait communiquer la cavité centrale (110) avec lextérieur, est disposée sur le couvre clou (200).
