What is also known as secondary segmental instability is one of the important causes of failed back syndrome. In this paper, we described a 45-year-old female patient who was diagnosed with secondary segmental instability caused by left L3 pars interarticularis fracture after a high lumbar disc surgery and was subsequently treated with re-operation. We evaluated the clinical course, diagnosis, and treatment methods for secondary segmental instability caused by postoperative pars interarticularis fracture. Furthermore, we emphasized the importance of preserving the pars interarticularis during upper lumbar disc surgeries in order to avoid a potential stress fracture.

This case report emphasizes the importance of coagulopathy resulting from fibrinogen deficiency during spinal surgical procedures and the necessity of a proper preoperative diagnosis.

These tumors share common arachnoid location with benign meningioma and mimic meningiomas in clinical and radiographic presentation. Because of the aggressive nature of the central nervous system HPs with high recurrence and distal metastasis rates the first line treatment is total resection with close follow ups postoperatively. In this report we tried to analyse the differentiation of hematoma and recurrence and evaluated the role of radiotherapy in light of the current literature.

The aim of this study was to reevaluate the side of the surgical approach in a selected group of patients with leg pain and contralateral lumbar disc herniation. Methods Included in this study were a total of 5 patients with lumbar disc herniations who presented with contralateral symptoms and neurological signs. In all cases, patients underwent a microdiscectomy from the side ipsilateral to the herniated lumbar disc, the side contralateral to the motor deficits and leg pain. Results The symptoms and signs, to some extent, resolved during the immediate postoperative period. There were no postoperative complications. Conclusions The findings confirm that performing a laminotomy via the side of the herniation is sufficient for this group of patients.
