Treatment of tibial pseudarthrosis with compression fixator

Pseudarthrosis remains a formidable complication of long-bone fractures, whatever their initial treatment. This complication is often poorly resolved by conventional treatments, with disappointing results. Through a retrospective study of 20 cases of tibial pseudarthrosis treated and followed up at the Department of Orthopaedic Surgery and Traumatology of the Habib Bourguiba University Hospital in Sfax (Tunisia), over a period of 06 years (2012 - 2017), we present an original technique based on the use of a monoplane external fixator in compression without cortico-spongy contribution while avoiding the opening of the focus as much as possible, and identifying the advantages and limitations of this operative technique. Pseudarthrosis was aseptic in 12 patients, and septic in 08. The rate of consolidation was 100% with an average delay of 3.5 months. Clinical and radiological results were assessed with a mean follow-up of 25.7 months. We assessed the therapeutic outcome according to the ASAMI classification, which has the merit of associating functional and anatomical results. Excellent and good results were obtained in 100% of cases.
