Associated injuries include concurrent Achilles tendon injuries, lower extremity fractures, talar dislocations, and bilateral calcaneal fractures [1-3]. In addition, studies have shown that 7-10% of calcaneal fractures are associated with a concomitant vertebral fracture, including compression or burst fractures, especially with high energy mechanisms such as a fall from height [1,2,5].
Pearl: Vertebral compression fractures are typically stable because they only involve the anterior column. Burst fractures result from a higher axial load and involve both the anterior and posterior columns. Neurologic deficits may occur from retropulsion of the posterior vertebral body into the spinal canal. Surgical indications depend on the location and severity of the fracture, neurologic injury, and stability of the posterior column .
