Factors affecting the fracture healing in treatment of tibial shaft fractures with circular external fixator.
This study aims to analyse the contribution of various risk factors for the delay of tibial shaft fractures treated by circular external fixator and predicting the high risk fractures for delayed union. 32 extraarticular tibial shaft fractures of 31 adult patients treated with circular external fixator were included. The patients were analysed according to age, energy of trauma, having an open fracture or not, AO classification, obliquity, use of supplementary fixation techniques in surgery, distance of fracture line to neighbouring rings, having a pin-track infection or not, reduction score, and smoking. There were eight delayed unions and two non-unions in our study. Consolidation time was significantly shorter (p=0.01) between the supplementary fixation group and the others. There was a significant difference in fracture healing time between pin-track-infected patients and the patients who did not have pin-track infection (p=0.037). In conclusion, our results indicate that non-union infection and not using supplementary fixation techniques are the major factors that delay the healing time. Supplementary fixation enhances the reduction rate and a low reduction score is related with the occurrence of a pin-track infection.
