Removal of intramedullary nails from the femur: a review of 45 cases.
The excellent biocompatibility of titanium and its alloys may result in osseointegration. In order to determine if this presents an obstacle to removal of intramedullary nails, we retrospectively reviewed a series of 45 cases of isolated removal of a femoral nail. Indications for removal were persistent pain and discomfort, request of an asymptomatic patient, or skeletal immaturity. Twenty-three nails were titanium, and 22 were stainless steel. Although removal of the titanium nails had a significantly longer operative time (110 vs. 84 min), analysis of variance indicated that this was due to a greater number of crosslocking screws in the titanium nails (2.2 vs. 0.6) and a tendency to set the titanium nails deeper in the femur. The use of the titanium material per se did not pose a risk factor for difficulty in late removal of an intramedullary nail.
