The results of traditional open surgery for herniated intervertebral disc are often limited by complications and failed back surgery syndrome (FBSS). Over the past few decades, a considerable amount of research has been done in the field of minimally invasive procedures as a treatment option for herniated intervertebral disc disease. Ozone disc nucleolysis is one such procedure which has results equal to or better than traditional surgery with virtually no complications. A 27-year-old post-partum female presented to the clinic with acute onset of severe lower back pain radiating to the left lower limb for one month. The pain started suddenly during labor and gradually increased over a period of few weeks post-partum. A magnetic resonance imaging (MRI) scan showed a large herniated disc bulge at the L4-L5 level causing severe radiculopathy. There was no bladder or bowel involvement. The patient was managed conservatively for three weeks. However, she failed to show any signs of improvement. She opted to undergo ozone disc nucleolysis under local anaesthesia. She showed significant improvement immediately after the procedure and there was further improvement in symptoms over a period of six weeks. Post-procedure follow-up at three months and six months showed significant improvement on the visual analogue scale (VAS), which was used to measure pain intensity and pain affect, along with the Oswestry Disability Index (ODI), which was used to measure the degree of disability due to the lower back pain.Her VAS score improved from nine to two at three months and finally to one at six months, whereas the ODI score improved significantly from 46 to 10 at three months and eventually to four at six months. Ozone disc nucleolysis is an efficacious, safe, durable, and cost-effective treatment option for mild to moderate cases of herniated intervertebral disc which are resistant to conservative management. However, randomized control trials are required to build a long-term database regarding the efficacy and durability of ozone disc nucleolysis as compared to other minimally invasive procedures and surgery. We strongly believe that the availability of long-term data on ozone disc nucleolysis would make it a more acceptable form of treatment for disc herniation as compared to traditional surgery.

Rupture of the internal carotid artery (ICA) during transsphenoidal surgery is a rare but potentially lethal complication. Direct surgical repair of the ICA may be difficult and time-consuming in an acute setting. Urgent endovascular treatments with vascular plug or stent-graft have been the feasible options to date. We desrcibe two cases of iatrogenic rupture of ICA during transsphenoidal surgery. In the first case we occluded the ICA with a vascular plug at the site of tear where cross circulation was adequate. In the second case we had to preserve the ICA with stent-graft since there was no adequate cross circulation. These two strategies are discussed below.

Background: Inherent complications associated with surgery and limited success of percutaneous minimally invasive procedures make researches wanting for an ideal treatment for cervical disc herniation. Objective: We prospectively study the role of ozone disc nucleolysis in cervical intervertebral disc herniation. Patients and Methods: From January 2008 to December 2020, we prospectively study 246 consecutive patients of cervical disc herniation treated by a single session of intradiscal injection of ozone–oxygen mixture (ozone disc nucleolysis). There were 55% of females and 45% of males. Age ranged from 28 to 68 years with a mean of 47. The outcome was measured on visual analog scale (VAS) scale and neck disability index (NDI) along with Mcnab method. Results: The mean baseline VAS score was 7.87 which became 3.09 at 1 month, 1.42 at 3 months, 1.40 at 6 months, and 1.35 at 1 year. The mean NDI was 36.27 at baseline which improved to 9.24 at 1 month, 6.25 at 3 months, 6.20 at 6 months, and 6.22 at 1 year. This was found to be significant with P < 0.05. Modified McNab criterion showed excellent recovery in 138 (56.10%), good recovery in 50 (20.32%), and fair recovery in 22 (8.94%), resulting in a successful rate of 85.36%. Mediocre recovery was seen in the remaining 36 patients amounting to a 14.64% failure rate. Conclusion: This study showed that ozone disc nucleolysis significantly reduces the pain related to cervical disc herniation along with a significant reduction in disability.
