Abstract
BACKGROUND
Calcaneal osteotomies correct hindfoot deformities and are often performed using a minimally invasive technique. The aim was to compare the safety of three calcaneal osteotomy techniques (oblique, chevron with apex anterior and chevron with apex posterior).
METHODS
Each osteotomy technique was performed on five cadavers (n = 15). These were then dissected to identify any injury to the neurovascular bundles. The distance between the burr and these structures was measured.
RESULTS
Using the apex posterior technique, the burr was closer to the medial and lateral neurovascular structures, and in one case the sural nerve was injured. There were no neurovascular injuries using the other techniques.
CONCLUSIONS
Minimally invasive surgery using a burr is generally a safe, reliable method for performing calcaneal osteotomies. The chevron with apex posterior osteotomy should be performed with caution given the closer relationship between the burr and neurovascular bundles. The other two techniques provide safer alternatives.
