Spontaneous Distal Extrusion of Kuntscher Intramedullary Nail

Abstract

Migration of femoral Kuntscher intramedullary nail (K-nail) proximally or distally within the femoral medullary cavity is a well-known documented complication, but spontaneous extrusion of a distally migrated K-nail is a rare complication. This is a case report of a 33-year-old lady who complained of sudden onset left knee pain and presented with spontaneous extrusion of a Kuntscher nail 12 years postinsertion. She underwent a successful K-nail removal surgery and showed a good clinical outcome after 6 months of outpatient follow-up.

Spontaneous Posterior Migration of an Antegrade, Reamed Intramedullary Tibial Nail Following Locking Bolt Removal, a Delayed Presentation

“…There has been a reported case of distal migration of a Küntscher tibial nail related to micromotion and subsequent bony erosion of the nail 16 years later [6]. This phenomena has been seen in the femur, again a stainless steel, slotted Küntscher nail with no locking screws [7,8]. However to our knowledge there have been no documented cases of migration of a reamed, locked, modern design titanium tibial nail following locking bolt removal.…”
