Glass foreign body in the lumbosacral junction of the spinal canal: a case report

Foreign bodies in soft tissue after trauma are common, and the smaller the wound, the easier it is to miss them. Moreover, undetected foreign bodies can lead to severe complications. A 60-year-old male patient presented to our emergency room with a 4-cm back laceration and a slightly decreased sensation in the left S1 dermatome after falling over a glass fish tank. A foreign body on the left side of the L5/S1 epidural space and S1 nerve root compression in the lateral recess were observed. Consequently, a midline longitudinal incision was made at the L5/S1 level, a paravertebral muscle subperiosteal dissection was performed, and the foreign body was carefully removed. Foreign bodies may exist even in simple, small wounds. Therefore, their presence should be confirmed or excluded through appropriate imaging and history-taking.
