Oculomotor nerve palsy (OMNP) is a well-recognized complication of posterior communicating artery (PCOM) aneurysms. Only a few comparative studies have assessed the effect of clipping versus coiling on recovery from OMNP in PCOM aneurysms. A retrospective review and meta-analysis was conducted to assess the relationship between PCOM aneurysm treatment and OMNP. ⋯ Complete recovery of OMNP with PCOM aneurysms is more commonly associated with surgical clipping than with endovascular coiling. Also, the degree of pre-operative OMNP and the treatment modality are significant factors that affect the complete recovery of OMNP.

A cadaveric study to determine the accuracy of percutaneous screw placement in the thoracic spine using standard fluoroscopic guidance. ⋯ This cadaveric study shows that percutaneous pedicle screw placement can be performed in the thoracic spine without a significant increase in the pedicle breach rate as compared with standard open techniques. A small percentage (4.4%) of pedicles, especially high in the thoracic spine, may not be safely visualized.

The optimal surgical treatment of recurrent lumbar disc herniation is controversial. ⋯ Revision discectomy is effective in patients with recurrent lumbar disc herniation. Fusion with revision discectomy improves the postoperative low back pain, decreases the intraoperative risk of dural tear or neural damage and decreases the postoperative incidence of mechanical instability or re-recurrence. TLIF and PLF have comparable results when used with revision discectomy, but PLF has significantly less total cost than TLIF.

Practical scenario in trauma neurosurgery comes with multiple challenges and limitations. It accounts for the maximum mortality in neurosurgery and yet the developing countries are still ill-equipped even for an emergency set-up for primary management of traumatic brain injuries. The evolution of modern neurosurgical techniques in traumatic brain injury has been ongoing for the last two centuries. However, it has always been a challenge to obtain a satisfactory clinical outcome, especially those following severe traumatic brain injuries. Other than the well-established procedures such as decompressive hemicraniectomy and those for acute and or chronic subdural hematomas and depressed skull fractures, contusions etcetera newer avenues for development of surgical techniques where indicated have been minimal. We are advocating a replacement for decompressive hemicranictomy, which would have the same indications as decompressive hemicraniectomy. The results of this procedure has been compared with the results of decompressive hemicraniectomy done in our institution and elsewhere and has been proven beyond doubts to be superior to decompressive hemicraniectomy. This procedure is elegant and can replace decompressive hemicraniectomy because of low morbidity and mortality. However, there is a steep learning curve and the microscope has to be used. ⋯ Extensive opening of cisterns making use of skull base techniques to approach them in a swollen brain is a better option to decompressive hemicraniectomy for the same indications.
