Revelation Lateral Flare Total Hip System

The Revelation^® Lateral Flare^® Total Hip System was designed based on a more complete understanding of hip joint biomechanics and bone morphology.

Hip Biomechanics
In 1917, John C. Koch published his extensive work on bony architecture of the human femur³. He believed the medial aspect of the femur to be under compressive load and most of the lateral cortex to experience tensile loading. Koch’s work became the standard by which hip biomechanics was analyzed. It did not, however, include soft tissue.

The Ilio-Tibial Band Model
The ilio-tibial band model, as presented by Dr. Fetto³, et al, extends Koch’s model by adding the ilio-tibial band as a lateral tension band. As a result, the lateral femur is shown to be under compression rather than tension during the unilateral stance phase gait. The lateral femur thus becomes a potential base of support for femoral components.

Bone Preservation and Regeneration
By respecting Wolff’s law, which states that bone is formed in response to the loading it experiences, the Revelation femoral component has been shown not only to preserve up to 95% of bone stock in primary surgeries, but to contribute to bone regeneration in revision surgeries with prior bone loss¹. Because of this feature , the Revelation Total hip System is suitable for younger, more active patients, in whom implant longevity is particularly important.

Primary Stability
By engaging the lateral femoral cortex as an additional base of support, the Revelation femoral component prevents stem subsidence and provides secure primary stability, which is a prerequisite for a long-term biological fixation. Compared to a straight stem, the Revelation stem has been shown to significantly less likely to migrate². In addition, the trapezoidal cross-section of the stem resists rotational forces. Due to its inherent stability, the Revelation stem allows for full postoperative weight bearing⁴.

Proximal Femur Load Transfer
By loading the lateral femur, the Revelation Hip System reproduces normal physiologic loading patterns, reduces potential for subsidence, and avoids diaphyseal overloading which has been sited as a cause of thigh pain.
