End cap missing the proximal end of the tibial interlocking nail to migrate posteriorly into the medullary canal: A complication that may be avoided

An End cap for an Intra- medullary nail is normally used to prevent bone overgrowth into the proximal end of the nail and to facilitate nail removal at a later date. End cap migration into the proximal redundant space in the medullary canal behind the nail is rare but an avoidable complication. Maintenance of a fixed position of knee flexion during reaming and nail insertion and the use of Cannulated End Cap systems with Image control and may reduce the incidence of this complication.
