An unusual cause of acute carpal tunnel syndrome: An undetected foreign body

Introduction: Carpal tunnel syndrome (CTS) is a trap neuropathy in which the median nerve is entrapped and compressed. Various factors have been implicated in its etiology and to date no single cause has been identified. In literature, foreign bodies following trauma have been rarely reported to compress the median nerve, resulting in CTS. Case Report: A 19-year-old male patient presented to our outpatient clinics due to symptoms of CTS. The patient had a history of hand injury with window glass. The patient was examined both in emergency department and then in family health center. In examination with palpation and X-ray graphics an undetected foreign body was found. Conclusion: The current report presents a case of an undetected foreign body that resulted in acute carpal tunnel syndrome, and which could be the subject of a medical malpractice lawsuit.
