Combination of anatomical locking plate and retrograde intramedullary nail in distal femoral fractures: comparison of mechanical stability

Biomechanical Stability of Juvidur and Bone Models on Osteosyntesic Materials

“…Group C is significantly more resistant in relation to groups B in the axial (p = 0.003), a torsional (p = 0.008). Thanks to its high biomechanical stability that allows early mobility LCP and IML in combination could be the treatment of choice in complicated A3 osteoporotic fractures of the distal femur in young people and adults ( 16 ).…”

Biomechanical comparision of femoral intramedullary nails for interfragmentary rotational stability

“…Their combined use may be a choice of treatment in patients with osteoporosis or high-energy trauma. [13] A limitation of our study is the utilization of composite femurs that could not accurately reproduce in vivo environments. Nevertheless, the composite femurs have been utilized successfully in biomechanical tests and produced more constant outcomes than cadaveric femurs which possibly have different bone mineral density and different biomechanical resistance.…”

“…Some researchers also investigated fatigue life of implant-femur constructs with cyclic tests. [13] For interlocking nails, numerous proximal nail migration cases were reported. [15,16] Proximal end of the compression nail may migrate more proximally as compression is performed during operation.…”

Distal femur fractures in adults

“…Reaming has the advantage of distributing bone graft and may stimulate blood flow. Biomechanical studies have shown retrograde nailing to be more resistant to axial load and load to failure 49 , and callus formation is increased when compared with locking plates 10 .…”
