Abstract

Huge teardrop fracture of the axis is an uncommon injury, mainly caused by high energy trauma. Despite of being described for the first time in 1956, the evidence is still scarce.

Purpose: To review the literature, analyze and discuss the treatment options and its results for this type of fracture. We present a clinical case of huge teardrop fracture of the axis.

Methods: Literature review between 1956 and 2020, discussion of the treatment options and results. Description of the treatment method and results in our mentioned clinical case.

Results: We present a patient with a huge teardrop fracture of the axis due to high energy trauma (parachute diving accident by malfunction of main device). Treatment decision is discussed considering the eventual benefits and risks, finally performing a C2-C3 anterior fusion augmented with iliac crest autograft. There are 79 cases described in the literature, but the cases solved by surgery are not more than 20.
