Screw migration of retrograde femur intramedullary nail with locking washer: A report of three cases

Blog Article

Background: There have been recent innovations in treatment of distal femur fractures, including new intramedullary nails with locking washer constructs meant to augment fixation and mimic intramedullary nail and plate combinations.The three patients in this report were treated with these new constructs.Case: This case report describes three patients sustaining intra-articular distal femoral fractures managed 15-eg1053cl with a novel retrograde femoral intramedullary nail with locking washer, who experienced migration of locking screws engaging the locking washer and nail.

Conclusion: Although the etiology is unclear, we must consider patient factors citronella horse shampoo that could result in delayed fracture healing, implant factors that may lead to compromise of this screw-washer interface, and surgeon factors.Further studies should be performed to evaluate the biomechanical loads experienced by the screw, and strategies developed to mitigate this complication.
