Tibial fractures treated with circular fixation: does the use of olive wires at the fracture site improve healing?
Clinical experience and published studies suggest that oblique fractures of the tibia are associated with delayed healing and non-union. Experimental studies have attributed this to increased shear at the fracture site. We have adopted the practice of using supplementary olive wires to reduce shear when using circular fixation for these fractures. A complete cohort of 54 oblique tibial fractures treated with the Sheffield Ring Fixator (Orthofix, Verona) was reviewed to elucidate the effect of using additional olive wires on fracture healing/treatment times. Fifty patients were studied in the final analysis. With low-energy injuries, the use of olive wires reduced treatment times significantly (no olives: 37 weeks, olives: 22 weeks, P<0.05), although this was not seen with higher energy injuries (no olives: 44 weeks, olives: 39 weeks, P=NS). There was no evidence of additional complications related to their use. We recommend the use of additional olive wires in the circular fixation of these difficult fractures.
