- When using the piriformis entry point for antegrade medullary nailing, an entry point too anterior will result in
- an increased risk for malalignment.
- an increased risk for iatrogenic fracture.
- an increased risk for a subcapital femoral neck fracture.
- weakness of the abductors with a resultant limp.
- difficulty with proximal locking screw placement
- an increased risk for iatrogenic fracture.
