The blade’s design enhances the rotational stability of the femoral head-neck fragment, crucial for minimizing risks such as cut-out, delayed union, and varus angulation in unstable trochanteric fractures.
Better Anchorage in the Femoral Head:
The specially designed tip of the blade facilitates bone compaction upon insertion. This compaction improves the anchorage of the implant, which is particularly beneficial in osteoporotic bone where traditional fixation methods may struggle.
Increased Support Surface:
The weight-bearing surface of the DHS Blade is larger compared to conventional DHS screws. This increased surface area allows the implant to support greater loads, reducing pressure on the bone and decreasing the risk of cut-out.
Reduced Cut-Out Risk:
The combination of enhanced rotational stability, improved anchorage, and a larger support surface collectively leads to a lower risk of cut-out, ensuring more reliable fixation and better patient outcomes.
