Abstract

Objective: To characterize the timing, indications, and "success rates of secondary interventions, dynamization and exchange nailing, in a large series of tibial nonunions" (dynamization and exchange nailing are types of secondary interventions). Setting: Retrospective multicenter analysis from level 1 trauma hospitals. Patients: A total of 194 tibia fractures that underwent dynamization or exchange nailing for delayed/nonunion. Intervention: Records and radiographs to characterize demographic data, fracture type, and cortical contact after tibial nailing were gathered. The radiographic union score for tibias (RUST) and the timing of intervention and time to union were calculated. Main Outcome Measures: The primary outcome was success of either intervention, defined as achieving union, with the need for further intervention defining failure. Other outcomes included RUST scores at intervention and union, and timing to intervention and union for both techniques. Two-tailed t tests and Fisher exact with P set at
