Risk of deep infection with intramedullary nailing following the use of external fixators.
A retrospective review was carried out to assess the incidence of deep infection occurring when intramedullary nailing was performed following the use of an external fixator. Three groups of patients were identified: group 1 in which the external fixator was used in initial fracture management (ten cases, nine patients), group 2 in which the external fixator was used in the management of established non-union (seven cases, seven patients), and group 3 in which the external fixator was used in limb lengthening procedures (eight cases, eight patients). All the 25 cases reviewed had clinical evidence of pin track infection before removal of the external fixator. After removal of the fixator it is our normal policy to wait for the pin sites to become dry before performing intramedullary nailing. In only one case, where there was a history of preceding recrudescent osteomyelitis, was there evidence of deep infection being reactivated following intramedullary nailing. We therefore conclude that pin track infection does not seem to be a contraindication to the subsequent use of an intramedullary nail, providing that underlying active osteomyelitis is not present. A delay of 7 to 14 days after removal of the fixator is recommended. Some problems experienced during nailing are highlighted, and solutions proposed.
