Core Tip
Core tip: Valgus intertrochanteric osteotomy is a viable treatment option for nonunion neck of femur. Size of the proximal fragment appears to be a significant predictive factor of fracture union. While valgus orientation of the proximal femur is important for fracture union, excessive valgus can lead to a poor functional outcome. The neck resorption ratio may be useful for measuring the proximal fragment and the head shaft angle may be useful for studying proximal femoral alignment in the presence of neck resorption.
