Buried versus unburied Kirschner wires in the management of paediatric lateral condyle elbow fractures: a comparative study from a tertiary centre.

There is little consensus on whether Kirschner wire (K-wire) burial is preferable in the management of paediatric lateral humeral condyle fractures. We identified 124 patients from May 2008 to August 2014. Sixty received buried K-wires and 64 received unburied wires. We found no significant difference in the infection rates between groups, but a high rate of skin erosion (23%) in the buried group, with a subsequent high rate of infection in this subgroup (40%). We found a strong association of wire erosion following early surgery. There is a considerable cost saving associated with using unburied wires. We therefore recommend the routine use of unburied wires.
