Iron Lady Hip periprosthetics

Iron Lady Hip periprosthetics

Periprosthetic hip fractures.


The design of periprosthetic plates has to overcome a number of technical issues. There is a high incidence of mobilisation of plates in multiple fractures, the presence of a prosthesis makes screw positioning difficult, and poor quality bone often results in screw pull-out and an early breakdown of the fracture.
Intrauma has developed a range of plates specifically for the treatment of periprosthetic fractures of the hip, knee and humerus. The use of O’nil periprosthetic plates ensures secure fixation of the fracture, early patient mobilisation and fracture healing times similar to normal fractures.
The patented conical screw locking system between the head of the screw and the holes in the plate ensures primary stability by equally distributing the forces along the length of the plate.
Pre-shaped plates with a semi-tubular profile simplify plate positioning and the multi-planar screw holes ensure optimum fixation even in more complex fractures.
The O’nil Iron Lady plate for periprosthetic fractures of the hip is a self-supporting structure where cerclage can be used simply to fix fragments in place rather than to support the plate. As with other O’nil plates, the unique screw locking mechanism minimises pressure on the bone, helping to preserve the vascularity of the periosteum, allowing early rehabilitation and reducing healing time.
