Abstract

Purpose

In line with several designs for osteosynthesis of femoral neck fracture (FNF), their effectiveness is still estimated by the results of biomechanical and clinical trials, finite element method (FE). But surgeons require the criteria which would define their properties in advance and allow improve the results of treatment.

Methods

When new implant (NI) is being designed, we developed such criterion – index efficiency of an implant (IEI) – and performed mathematical comparative researches of properties of NI with the known designs. We analyzed the results of comparative clinical trials on treatment of FNF with various implants considering their IEI.

Results

Analysis showed that results of comparative clinical trials with the use of various implants for osteosynthesis FNF completely correlated to their IEI; IEI of the NI two to three times exceeds IEI of all known designs, and the destruction percentage of a bone tissue is two to three times less when it is applied.

Conclusion

The offered IEI can be used for designing new implants and allows improving the results of treatment of patients with FNF by optimizing the choice of implant for osteosynthesis.
