ORTHOPEDIC EXTERNAL FIXATION DEVICE

摘要

Devices for the fixation of a bone fracture and methods of using the devices are provided. The devices comprise at least one distal pin assembly configured to engage a first bone fragment, at least one proximal pin assembly configured to engage a second bone fragment, and a rail bar system configured to connect the distal and proximal pin assemblies together across the bone fracture. Each pin assembly includes a screw portion having a distal end configured to engage first bone fragment and a proximal end, a support sheath portion having a distal end configured to engage the first bone fragment, wherein the support sheath portion defines an elongated channel in which the proximal end of the screw portion is disposed, and a cap portion configured to attach the proximal end of the screw portion to the support sheath portion.

1. A device for fixation of a bone fracture comprising:
a. at least one distal pin assembly configured to engage a first bone fragment, said distal pin assembly comprising (i) a screw portion having a distal end configured to engage the first bone fragment and a proximal end, (ii) a support sheath portion having a distal end configured to engage the first bone fragment, wherein the support sheath portion defines an elongated channel in which the proximal end of the screw portion is disposed, and (iii) a cap portion connecting said proximal end of said screw portion to said support sheath portion; b. at least one proximal pin assembly configured to engage a second bone fragment, said proximal pin assembly comprising (i) a screw portion having a distal end configured to engage the second bone fragment and a proximal end, (ii) a support sheath portion having a distal end configured to engage the second bone fragment, wherein the support sheath portion defines an elongated channel in which the proximal end of the screw portion is disposed, and (iii) a cap portion configured to attach said proximal end of said screw portion to said support sheath portion; and c. a rail bar system configured to connect said cap portion of said distal pin assembly to said cap portion of said proximal pin assembly.
