Aseptic nonunion of the tibia treated by plating and bone grafting: retrospective study about 40 cases.

Abstract

The objective of this study was to evaluate the clinical and radiological results of the treatment of aseptic nonunion of the tibia by plating and bone grafting. This retrospective study included 40 patients with aseptic nonunion of the tibia, treated in the Trauma-Orthopedic department B4 of CHU Hassan II in Fez-Morocco. The average age was 41 years (range 25-60 years). The initial fractures were in the middle third of the tibia for the majority of our patients. We used the ASAMI criteria to assess the results. We found 45 patients with aseptic nonunion of the tibia who were treated by the same surgical team and followed in postoperative consultation for a fixed period of 10 months. Three patients lost to follow-up and two patients refused the treatment. In 37 patients (92.5%), union was obtained after a mean delay of 4.3 months (range 3-7 months). The average time from initial treatment to treatment for nonunion was eight months (range 6-10 months). According to the ASAMI classification, bone results were excellent in 26, good in 8, fair in 3 and poor in 3; functional results were excellent in 10, good in 16, fair in 11 and poor in 3. Our study suggests that the combination of screwed plate and autograft in the treatment of aseptic nonunion of the tibia has provided satisfactory results. A well-codified management of the initial fracture remains the gold key to prevent the occurrence of pseudarthrosis.
