Abstract
Distal third tibial fractures are prone to non-union following tibial nail insertion. The purpose of this study was to assess the union of distal third tibial fractures in patients who have undergone intra-medullary (IM) tibial nailing with one versus two distal locking screws. Sixty-five patients who had intramedullary tibial nail fixation were retrospectively analysed. Our results showed that 80% of non-unions in distal third fractures had only one distal locking screw compared to 20% who had two distal locking screws. This is statistically significant (p<0.01). We therefore conclude that two distal locking screws are essential for distal third fractures.
Résumé
Les fractures du tiers distal du tibia sont réputées entraîner des retards de consolidation après enclouage. Le propos de cette étude est d’étudier la consolidation de ce type de fracture chez les patients ayant bénéficié d’un enclouage centro médullaire avec une ou deux vis de verrouillage distal. 65 patients ont ainsi été analysés de manière rétrospective. Les résultats sont les suivants 80% des pseudarthroses avait une seule vis de verrouillage distal alors que seulement 20% des pseudarthroses sont survenues chez les patients ayant un verrouillage avec deux vis distales. Il existe une différence significative (p < 0.01) entre ces deux techniques, le verrouillage distal avec deux vis est essentiel dans ce type de fracture.
