Compartment pressures after intramedullary nailing of the tibia.

Intracompartmental pressures of 66 patients with 67 tibial fractures treated by intramedullary nailing were monitored. There was no difference in the pressures recorded between the different Tscherne fracture types, between open and closed fractures, between low energy and high energy injuries or between fractures dealt with early and those not treated until more than 24 hours after injury. The overall incidence of acute compartment syndrome was 1.5%. No patient developed any sequelae of compartment syndrome. We conclude that intramedullary nailing does not increase the incidence of acute compartment syndrome in tibial fractures and that delay does not reduce the risk of raised compartment pressures.
