Traumatic Open Extrusion of the Posterior Facet of the Calcaneus: A Case Report

Traumatic extrusion of the posterior facet of the calcaneus is a rare phenomenon that has seldom been reported on. In this report, we describe a 46-year-old woman who sustained an open right calcaneal fracture with extrusion of the posterior facet after motor vehicle collision. The fragment was reinserted, then underwent definitive fixation. Postoperatively, patient went on to radiographic union and with return to work with little to no residual pain.

Reinsertion of the fragment with temporary fixation with subsequent definitive fixation is a viable option for extrusion a tarsal bone, specifically of the posterior facet of the calcaneus.
