The kyphosis of the fractured segment will be assessed by the angle formed by the line parallel to the superior vertebral plate of the vertebra proximal to the fractured vertebra and by the line of the inferior vertebral plate of the vertebra distal to the fractured vertebra The sagittal index of the fractured segment (Farcy Index) will be calculated using the height of the proximal vertebra (A1), height of the fractured vertebra (A2) and height of the distal vertebra. Sagittal index of the fractured segment = (A3): 100- (2xA2 / A1 + A3) x100.
