Abstract

An internal intramedullary fixation device for the stabilization of bone in arthrodesis and fractures of the foot and hand is disclosed. During implantation in medullary canals of bones, the device grasps the edges of the canals, stabilizing the bones, internally, during a healing process. The intramedullary fixation device comprises arrow-shaped proximal and distal heads comprising tips and a pairs of wings, the heads being sized to fit within an intramedullary canal of a bone. The intramedullary fixation device also comprises a rigid body defining a longitudinal axis connecting the proximal and distal heads. The rigid body comprises an intermediate portion, a distal neck portion connecting the rigid body to the distal head, and a proximal neck portion connecting the rigid body to the proximal head, the neck portions having a cross-sectional area smaller than a cross-section area of the intermediate portion.

Abstract

An internal intramedullary fixation device for the stabilization of bone in arthrodesis and fractures of the foot and hand is disclosed. During implantation in the medullary canal of each bone, the device grasps the edges of the canal, stabilizing the bone (internally) during the natural healing process.

Abstract

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.

Abstract

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.
