Key result
DHS guide wire with a coupling screw facilitates removal of broken PFNA-II anti-rotation blades.
Why the study?
Removing broken or stripped PFNA-II blades in intertrochanteric fractures is technically difficult, and few methods exist when other procedures have failed.
Does the insertion of a DHS guide wire with a coupling screw facilitate the removal of a broken PFNA-II blade in patients with intertrochanteric fractures?

Does the insertion of a DHS guide wire with a coupling screw facilitate the removal of a broken PFNA-II blade in patients with intertrochanteric fractures?
A novel technique using a DHS guide wire with a coupling screw provides a simple and cost-effective approach for extracting broken PFNA-II blades.
May aid broken PFNA-II blade extraction; hypothesis-generating and requires prospective validation before adoption.
Introduction: Proximal femoral nail antirotation - II (PFNA- II) is a common treatment for intertrochanteric fractures in the elderly. Removing PFNA is difficult in rare circumstances due to blade head stripping or breaking. In this article, we endeavored to explain an easy methodology that can be utilized to remove stripped, damaged anti-rotation blades for which few had been formulated but other procedures have failed. Materials and Methods: In four cases, one case is discussed 15 months following the prior fixation; the individual underwent PFNA removal surgery for a broken implant causing pain. We had trouble removing the anti-rotation blade with the standard equipment. Result: The procedure assisted us in removing the anti-rotation blade and provided a favorable outcome for the patient. Conclusion: The insertion of a DHS guide wire with a coupling screw for inserting DHS screw in conjunction with a proximal femoral anti-rotation blade may be a cost-effective and simple approach to dealing with extraction failure.

Jain et al. (2024) conducted a case report in Broken PFNA-II blade in intertrochanteric fractures (n=4). Insertion of a DHS guide wire with a coupling screw was evaluated on Successful removal of the anti-rotation blade. The insertion of a DHS guide wire with a coupling screw successfully facilitated the removal of a broken PFNA-II anti-rotation blade in 4 cases.
