Acute compartment syndrome in tibial diaphyseal fractures.

We reviewed 25 patients with tibial diaphyseal fractures which had been complicated by an acute compartment syndrome. Thirteen had undergone continuous monitoring of the compartment pressure and the other 12 had not. The average delay from injury to fasciotomy in the monitored group was 16 hours and in the non-monitored group 32 hours (p < 0.05). Of the 12 surviving patients in the monitored group, none had any sequelae of acute compartment syndrome at final review at an average of 10.5 months. Of the 11 surviving patients in the non-monitored group, ten had definite sequelae with muscle weakness and contractures (p < 0.01). There was also a significant delay in tibial union in the non-monitored group (p < 0.05). We recommend that, when equipment is available, all patients with tibial fractures should have continuous compartment monitoring to minimise the incidence of acute compartment syndrome.
