The Effect Of Implant Overlap On The Mechanical Properties Of The Femur (Visit this link)

Journal of Trauma-Injury Infection & Critical Care. 54(5):930-935, May 2003. Harris, Timothy MD; Ruth, John T. MD; Szivek, John PhD; Haywood, Brett MD Conclusion : Strain patterns are altered by the degree of implant overlap in the proximal femoral diaphysis. Femora with uninstrumented intervals between retrograde nails and side plates fail at lower loads than femora without retrograde nails and those with kissing or overlapping implants. Kissing or overlapping instrumentation increases load to failure and creates a more biomechanically stable construct than gapped implants. The findings of this study suggest an overlapping implant orientation in the femur increases failure load at the implant interface.
