Abstract
Purpose
To evaluate the efficacy of the augmentative locking compression plate fixation in the treatment of femoral shaft nonunion occurring after intramedullary nailing.
Materials and Methods
Between July 2004 and September 2012, a total of 17 patients (twelve men, five women, average age 52.5 years) who had femoral nonunions after primary intramedullary nailing for femoral shaft fractures were reviewed. The mean period of nonunion after primary nailing was 18.5 months. Leaving the nail in situ, an augmentative locking plate was applied to the nonunion site with simultaneous autogenous bone grafting, except for five hypertrophic nonunions. We followed up all patients with plain radiograph and evaluated clinical status to determine bone union.
Results
All patients demonstrated evidence of fracture union with an average follow-up time of 5.0 (range 2 to 9) months. The time of operation was an average of 115 (range 45 to 160) minutes, and mean blood loss was 345.9 (range 150 to 700) ml. Two patients noted discomfort at the distal portion of plate, and one noted discomfort of donor site, but functional limitation was not observed in all patients.
