摘要： Surgical methods and fixation devices for bone fixation and stabilization on a patient include exposing at least a portion of a first phalanx and a second phalanx at a joint of a patient; creating a passage in an intramedullary canal of the first phalanx; inserting a first head portion of a fixation device along the passage in the intramedullary canal in a translating manner past the cancellous bone in the phalanx until the head portion engages the subchondral bone at a base of the first phalanx, the fixation device having an opposing second head portion extending out of the passage from the first phalanx; and introducing the second phalanx onto the second head portion so that the second head portion anchors in the second phalanx.

摘要： An intramedullary fixation device used in bone fixation and stabilization on a patient includes a longitudinally extending rigid body, a distal head disposed at a distal end of the body and sized for insertion into an intramedullary canal of a phalanx of the patient, the distal head having a central core portion and a plurality of extending distal wings radially projecting from the central core portion. A proximal head at a proximal end of the body is sized for insertion into an intramedullary canal of a phalanx of the patient. It has a central core portion and a plurality of proximal wings extending radially outwardly from the central core portion.
