[Traumatic epiphysiolysis of the dens axis-a 10-year follow-up].

Abstract

Epiphysiolysis of the dens axis is a rare injury in childhood but should be reliably investigated in the presence of typical pathological mechanisms. In our case, the injury in a four-year-old boy after a fall on his neck could not be diagnosed in the initial X‑ray. The diagnosis was made by means of an MRI scan performed during the course of the case and conservative treatment with a cervical collar was provided. The 10-year follow-up showed mild impairments, especially when remaining in a flexed position for long periods (e.g. when reading). In addition, the question arises retrospectively as to whether an additional injury to the C2/3 led to spontaneous fusion of the segment.
