A heterotopic ossification related to temporary placement of a skull bone flap

Case report

Restricted access

✓The authors report on a 19-year-old man who sustained a traumatic brain injury. Following decompressive craniotomy, he suffered from an unusual heterotopic ossification due to the temporary placement of the skull bone flap in his thigh. To the best of the authors' knowledge, this is the first time that a possible causal relationship between these entities has been reported in the literature.

Abbreviations used in this paper: HO = heterotopic ossification; TBI = traumatic brain injury.
