Treatment strategy for osteoporotic vertebral body fractures in the lumbar spine: a case report and literature review

Abstract

This report describes the successful treatment of an osteoporotic compression fracture. A 74-year-old woman presented with severe low back pain and left sciatica that had lasted for 6 weeks. Four week of conservative treatment was not effective. The patient was bedridden and had difficulty walking. A past history of osteoporosis was noted. Multilevel compression fractures, central stenosis, and spondylolisthesis with overt instability were evident in the preoperative images. Decompression and fusion surgery, vertebroplasty, and preoperative and postoperative teriparatide administration were planned. A severe endplate injury in the lower vertebral body was detected during interbody fusion surgery using an anterior approach. Additional screw insertion with posterolateral fusion was planned to prevent aggravation of cage subsidence. Postoperative magnetic resonance imaging, computed tomography (CT), and X-ray images revealed sufficient decompression, no cement leakage, and no nerve injury. On the first postoperative day, the patient reported that the left sciatica symptoms had improved. Satisfactory ambulation was observed at the outpatient department after 6 months. Fusion in progress was evident on follow-up CT and X-ray images. This case offers insights into possible treatment strategies for osteoporotic compression fractures with severe endplate injury, overt instability, and radiculopathy of the lower lumbar spine.
