Biomechanical comparison of locking femoral neck plate versus cannulated screws with or without a medial buttress plate in Pauwels type 3 femoral neck fractures

The results of this biomechanical study showed that the LFNP fixation system provided su"cient biomechanical stability for unstable Pauwels type 3 femoral neck fractures. The biomechanical performance of LFNP was similar to that of cannulated screws with medial buttress plate and better than that of cannulated screws alone. This suggests that LFNP can be a promising stable alternative fixation method to cannulated screws with a medial buttress plate in unstable femoral neck fractures.
