Fig. 2From: J-bone graft with double locking plate: a symphony of mechanics and biology for atrophic distal femoral non-union with bone defectCalculations of loading force and fracture gap. a Schematic of the loading force from the focal point of the femoral head to the midpoint of the femoral condyle. b Three lines from a to a’, from b to b’, and from c to cc’ are used to calculate the axial micromotion of the fracture gapBack to article page
