PRIMARY UNREAMED NAILING IN GRADE I, II AND IIIA OPEN FRACTURES OF THE TIBIA SHAFT: A PROSPECTIVE STUDY OF THE OUTCOMES IN 80 PATIENTS

Abstract

Introduction. To evaluate the incidences of union, nonunion and infection in the treatment of open tibial shaft fractures of Gustilo–Anderson types I, and IIIA treated with primary unreamed solid intramedullary locked nail (UTN). Materials and Methods. It is a prospective study of 80 open tibial shaft fractures. According to the AO classification, 36 patients (44%) were of type A, 29 (36%) were of type B and 15 (18%) were of type C. According to the Gustilo–Anderson classification, 31 patients (38.7%) were of grade I, 24 (30%) were of grade II and 25 (31%) were of grade IIIA. For the definitive stabilization of the fracture was used a UTN. Results. Bone healing was achieved in 98.4% of the cases, with a mean time of 24.2 weeks, ranging from 14 weeks to 110 weeks. Union without infection was seen in 70 patients (87%) and nonunion was seen in five patients (6%). Deep infection was seen in three patients (3.7%) and malunion was seen in two patients (2.5%). Conclusion. The treatment of open tibial shaft fractures with unreamed solid intramedullary locked nail allows high rates of bone healing and low rates of nonunion and deep infection, and if the presence of infection is excluded, then the results of unreamed nailing and reamed nailing are the same.
