It turned out that Ms. Lu was crushed by a railcar at work, resulting in lumbosacral swelling and pain, impaired mobility and weakness of both lower limbs. After the injury, the patient was rushed to the emergency department of our hospital by her family and colleagues, and due to the seriousness of her condition, she was admitted to the Department of Surgery of our hospital to continue resuscitation treatment. On admission, the patient had a blood pressure of 90/40 mmHg, abdominal muscle tension, and abdominal aortic pulsation could be detected. He had significant lumbar pressure pain and limited activity. CT showed that the left kidney was contused, the lumbar 5 vertebra was completely dislocated into the pelvis, and the cauda equina was completely transected. Admission diagnosis: complete dislocation of lumbar 5/sacral 1 with complete paralysis and left renal contusion. The medical and nursing staffs of the Department of Surgery of our hospital mobilized urgently and extended a loving helping hand to the patient’s family who was in great grief. Under the unified command of Vice President Lin Bendan and Deputy Director Hu Yishan, colleagues and patients worked closely with each other, administering oxygen, monitoring cardiac electricity, replenishing fluids to stabilize vital signs and abdomen, and stabilizing the spine to prevent secondary injuries. After 3 days of active resuscitation and close observation, the patient’s vital signs gradually stabilized. On the 5th day after the injury, the patient underwent a posterior approach lumbar 5/sacral 1 complete dislocation dissection, intervertebral fusion and spinal decompression internal fixation with the assistance of Dr. Ganxuan Zheng and Dr. Yanzhang Shi, with the close cooperation of anesthesiologists and nurses. The operation took 5 hours and 30 minutes, with 1600 ml of intraoperative bleeding, and was successfully completed. Three days after the operation, the patient’s muscle strength of both lower limbs recovered from preoperative level 0 to level III, and the function of urination and defecation also partially recovered, and the repeat CT examination indicated that the sequence of lumbosacral spine was completely restored to normal. At present, the patient is undergoing further rehabilitation treatment, and the leaders of the Taiwan enterprise where the patient is located also give great care, support and help to the rescue treatment of the patient. According to Deputy Director Hu Yishan, such a serious lumbar 5/sacral 1 complete dislocation and complete paralysis is the first case in our hospital, and according to the literature, similar serious lumbar 5/sacral 1 dislocation is also rare at home and abroad. Life is fragile, but as long as we use love and true feelings, we can build the Great Wall of Life. In the face of disaster, the friendship between compatriots on both sides of the Taiwan Strait is touching. At present, the patient is recovering well and can miraculously walk on the ground, and will be discharged from the hospital on the same day. Pre-operative 3D reconstruction CT of the pelvis indicated complete dislocation of L5/S1 Post-operative indicated that L5/S1 was repositioned and the internal fixation was in good position.
