Abstract
The instant invention is a novel method and apparatus for minimally invasive treatment of unstable pelvic ring injuries combined with fixation of acetabular cup assemblies for total hip arthroplasty. Fixation means and acetabular cup assemblies are affixed to the ilia and subcutaneous anteriorly bowed elongated rods/plate including possibly a subcutaneous posterior plate are connected between the fixation means.
Claims14
A surgical method for combined fixation of minimally invasive treatment of unstable pelvic ring injuries and full hip arthroplasty comprising the steps of:
- affixing at least one fixation means and acetabular cup assembly to each of a first and second ilium of a pelvis;
- said fixation means comprising a threaded rod which is inserted into the ilium at the ASIS and extends through the ilium to the PSIS, said acetabular cup assembly being positioned in an acetabulum of at least one of said first and second ilium and fastened to said acetabulum/ilium by said at least one fixation means;
- attaching a rigid anteriorly bowed subcutaneous elongated anterior plate to at least one of said fixation means on each of said first and second ilium, anterior to the pelvis;
- and
- attaching a subcutaneous posterior plate to at least one of said fixation means on each of said first and second ilium, posterior to the pelvis.

The surgical method of claim:
- 1, wherein said step of affixing said threaded rod comprises the steps of:
- creating a longitudinal incision centered on the Anterior Superior Iilac Spine (ASIS);
- bluntly dissecting through the soft tissues;
- using fluoroscopic imaging to identify the starting point for the threaded rod;
- opening a cortex of the ilium at said starting point with a drill;
- establishing a corridor between inner and outer cortices of the ilium using a pedicle finder;
- and
- screwing said threaded rod into said corridor.
