Hyoid fracture: consensual sex-play or non-consensual nonfatal strangulation: a case report.

Abstract

Hyoid fractures are uncommon, but when they occur they are commonly the result of strangulation or hanging. Although there is a lack of available quantitative data, there is increasing evidence to suggest that strangulation is a relatively common feature of consensual sex play. This creates difficulty in clinical forensic medicine given the "rough sex" defence has previously been used successfully in cases of fatal intimate partner strangulation. We present a case where consensual and non-consensual strangulation has occurred in a woman who presents with a hyoid fracture. While manual strangulation was thought to be a more likely mechanism than consensual wearing of a sex-collar; ultimately the similar timeframes of the collar-wearing and the non-consensual manual strangulation meant that the accused was not convicted of this particular strangulation offense. This case highlights the importance of further research into consensual strangulation and the incidence of resultant injuries. It also demonstrates the importance of collecting a detailed forensic history and adequately documenting injuries in a contemporaneous matter.
