The purpose of this study is to report a rare case of a non-iatrogenic spontaneously resolved spinal subdural haematoma or SSDH following transforaminal lumbar interbody fusion or TLIF revision and its possible explanation. The researchers evaluated a case report of a 40-year-old man with a history of the persistent lower back. They left lower extremity radicular pain, secondary to recurrent disc prolapse, lumbar spondylosis with foraminal stenosis. He underwent an L5/S1 transforaminal interbody fusion via a right-sided approach (through previous lumbar microdiscectomy incision). They discovered that, on postoperative day two, the patient developed headaches and photophobia secondary to an acute thoracolumbar subdural haematoma with no objective neurological deficit.

After closely observing his neurological status and conservative management of the subdural haematoma, the patient fully recovered from his symptoms and remained problem-free at a 2-year follow-up. Although the occurrence of an acute spinal subdural haematoma after spinal surgery is a rare complication following spinal surgery, its appropriate management relies on early recognition if significant morbidity is to be avoided. However, the researchers are sticking to this study to come up with some new opening to the world of spine surgery.
