Application of lesser trochanteric reduction fixator in the treatment of unstable intertrochanteric fractures.

Background: Closed reduction and internal fixation with intramedullary nails has been widely accepted for treating intertrochanteric fractures.

Aim: To focus on how to avoid displacement of the lesser trochanter in unstable intertrochanteric fractures.

Methods: We developed a lesser trochanteric reduction fixator for treating intertrochanteric fractures through fixing the lesser trochanter by combining the loop plate through the fixator after reduction by the reducer.
