Systems and methods for the fixation or fusion of bone
A stem-like bone fixation device allows for bony in-growth on its surface and across fracture fragments or between bones that are to be fused.
1 . A bone fixation device for stabilizing bone segments
comprising a stem adapted for passage between bone segments, at least a portion of the stem including a surface permitting bony in-growth.
2 . A bone fixation device as in claim 1
wherein the stem structure is of a cylindrical configuration.
3 . A bone fixation device as in claim 1
wherein the stem is of a conical configuration.
4 . A bone fixation device as in claim 1
wherein the stem is cannulated.
5 . A bone fixation device as in claim 1
wherein the stem includes a threaded end portion for coupling with another stem.
6 . A bone fixation device as in claim 1
wherein the stem comprises a prosthetic material.
7 . A bone fixation device as in claim 1
wherein the stem comprises a biologic material.
8 . A bone fixation device as in claim 1
wherein the stem includes a fenestration permitting passage of another stem.
9 . A bone fixation device as in claim 1
wherein the stem is cannulated.
10 . A bone fixation device as in claim 1
wherein the stem is threaded.
11 . A bone fixation device according to claim 1
further comprising a coupling to couple the stem with another stem:
12 . A method for bone fracture fixation using the bone fixation device as defined in claim 1 .
13 . A method for bone fixation using the bone fixation device as defined in claim 1.
