Forensic evaluation of alleged wrist restraint/handcuff injuries in survivors of torture utilizing the Istanbul Protocol.

Despite being a common form of abuse, there is a paucity of literature describing shackling and wrist restraint injuries among survivors of torture. Forensic evaluation of alleged wrist restraint/handcuff injuries in survivors of torture presents challenges to the evaluator, especially if the injuries are remote and do not leave lasting marks nor neurologic deficits. Thorough history-taking and physical examination are critical to effective forensic documentation. Guidance is provided in The Manual on Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (Istanbul Protocol), the gold standard for the medicolegal documentation of torture. This guidance relies primarily on physical findings, with less direction provided on how to interpret historical evidence or when historical evidence provided by the patient can be interpreted as highly consistent with alleged injury in the absence of current physical findings. Through a case-based review, we present diagnostic strategies for the evaluation of alleged abuse involving wrist restraints/handcuffs, focusing on skin, neurologic, and osseous injuries. We highlight key findings from both the history and physical examination that will allow the evaluator to improve the accuracy of their expert medical opinion on the degree to which medical findings correlate with the patient's allegations of wrist restraint injuries.
