Abstract
Methods and devices for treating fractures in or adjacent the wrist and distal forearm employ an intramedullary interlocking fixation rod (i.e, it interlocks the distal and proximal fracture fragments together) to stabilize the skeletal structure in a manner which can inhibit the amount of collapse or loss in skeletal length exhibited by a patient with a distal radius fracture.
Claims23
An internal fixation device for treating or repairing a distal radius fracture of a patient, the distal radius fracture having a fracture line forming distal and proximal fracture fragments, said device comprising:
- an elongated fixation rod configured and sized to reside within the distal radius and having distal and proximal portions, said distal portion including a head with a laterally extending distal aperture formed therein and said proximal portion being sized and configured such that, in position, it resides in a portion of a medullary canal of the radius, wherein said elongated fixation rod has a curvilinear profile comprising a substantially linear proximal portion configured to axially extend within the medullary canal of the radius and a curved distal portion configured to extend from the proximal portion into a metaphysis region of the distal radius, and wherein the distal aperture is configured to receive a distal fixation member for attachment of said rod to the distal fracture fragment.
An internal fixation device for treating or repairing a distal radius fracture of a patient, the distal radius fracture having a fracture line forming distal and proximal fracture fragments, said device comprising:
- an elongated fixation rod configured and sized to reside within the radius and having distal and proximal portions, the rod comprising a plurality of attachable segments, said distal portion including a head with a laterally extending distal aperture formed therein and said proximal portion being sized and configured such that, in position, it resides in a portion of a medullary canal of the distal radius, wherein said elongated fixation rod has a curvilinear profile comprising a substantially linear proximal portion configured to axially extend within the medullary canal of the distal radius and a curved distal portion configured to extend from the proximal portion into a metaphysis region of the distal radius, and wherein the distal aperture is configured to receive a distal fixation member for attachment of said rod to the distal fracture fragment, the distal portion of the rod being configured for removable attachment to a drill guide adapted for guiding placement of a fixation member through the rod.
