Biomechanical evaluation of femoral neck fracture osteosynthesis

Bone geometry, density, and thickness of the cortical layer femoral neck (FN) contribute to mechanical strength in osteosythesis fractures (FNF) young adults. The available techniques for fracture fixation FN are reviewed with respect biomechanical stability. A study osteosynthesis stability FNF three cannulated screws was carried out using synthetic models proximal part bone (FB). experimental were divided into 4 groups. Each group related configuration FN. vertical horizontal assessed two series load. In I, loaded forces longitudinal axis FB II, acted perpendicular direction axis. loading evaluated when displacement 2 mm fragments achieved. highest strengths obtained I both ‒ 1898 N a load 1046 Further, decreasing order, results groups III IV. this study, it found that consideration position according architectonics is crucial fragment triangular points contact compact ensures maximum construct fractures, which comparable normal walking conditions. We hypothesize manner could provide better inserted dense tissues relation architectonics. To ensure stability, each screw should have – lateral wall subtrochanteric region FB, inner FN, head. New screws’ placement neutralization share fractures.
