Universal Locking Trochanter Stabilization Plate

The Universal Locking Trochanter Stabilization Plate is intended to treat stable and unstable intertrochanteric, subtrochanteric, pertrochanteric, and basilar neck fractures when used in conjunction with the Dynamic Hip Screw (DHS) or the LCP Dynamic Helical Hip System (DHHS) side plates with 4 or more holes.

Using the plate limits the possibility of varus deformation of the proximal fragment, with cut out of the screws and medialization of the distal femoral fragment, without impairing function and dynamization capacity of the DHS.

The Universal Locking Trochanter Stabilization Plate limits diaphyseal medialization by fastening onto the greater trochanter relief. The additional proximal internal fixation can be achieved by using 3.5 mm locking head screws. Cerclage is still possible.

With the introduction of the DHHS and the combination holes, the existing Locking Trochanter Stabilization Plate designed for use with the DHS only, had to be adapted.

The changes of the Universal Locking Trochanter Stabilization Plate are:

  • In the proximal hole of the plate shaft the size of the slot/cut out was enlarged to allow for placement of the DHHS compression screw, which is bigger than the DHS compression screw.
  • The second most distal hole was enlarged to accommodate screw placement in both DHS and DHHS.
  • The most distal hole was changed to a double hole for affixing the plate to the bone through both the DHS and DHHS, which enlarges the plate.
