Abstract

PURPOSE
Our study was aim to evaluate the results of treatment by antibiotic cement-coated unreamed nailing for infected nonunion of long bone shaft.
MATERIALS AND METHODS
Ten cases of nonunion, 6 femurs and 4 tibias were included in this study. Average age of patients was 38.5 and men were eight. Average follow-up period was 16.4 months (12-35) . Etiologies of infection were open fractures (6 cases) and iatrogenic (4 cases) . Eight cases which had positive antimicrobial sensitivity test preoperatively were used a sensitive, heatstable, and powderform antibiotics. Primary autogenous bone grafting with nailing was perfomed in five cases. Delayed bone grafting after curettage and nailing was done in another five cases in infected by S. aures organism.
RESULTS
All of ten cases had bony union. Union time was average 31.5 in femur and 26.4 in tibia. Early weight bearing ambulation and motion of adjacent joint were beneficial. But average 8 mm of shortening was developed and angulation more than 5 degrees occured in one case.
CONCLUSION
Antibiotic cement coated-unreamed intramedullay nailing is the recommended treatment of method in infected nonunion of long bone shaft with minimal shortening.
