We report the first extraforaminal location of a lumbar discal cyst. The patient was treated by hemilaminectomy, arthrectomy, cyst resection, and unilateral arthrodesis, achieving complete release of the nerve root. Extraforaminal lumbar discal cyst may represent an unexpected cause of sciatic pain with favorable outcome after surgical resection.

To investigate effect of July admission on short-term outcome after endovascular coiling of patients with subarachnoid hemorrhage (SAH) owing to ruptured aneurysms. ⋯ Based on findings of this national investigation, patients with SAH owing to ruptured aneurysms who undergo endovascular therapy during the beginning of the academic year in July may not have worse short-term outcome compared with patients with admissions during other months.

Meningiomas of the clinoid region pose a formidable surgical challenge. Pterional craniotomy is the traditional approach and is often associated with high-risk postsurgical morbidities. In the current presentation, we describe an elderly male with a clinoidal meningioma who underwent a minimally invasive supraorbital craniotomy for tumor resection. ⋯ Initial intraoperative steps include dissection via the corridor between the carotid artery and the tentorium, as well as exposing the tumor in the opticocarotid triangle, followed by tumor dissection using microsurgical techniques. Care must be taken to preserve the supraorbital nerve to prevent frontal numbness and avoid violation of the frontal sinus to prevent postoperative cerebrospinal fluid leak. Emphasis on using this minimally invasive procedure for clinoidal meningiomas over the pterional approach for a select cohort of patients is laid, considering the cosmetic merits and adequate extent of tumor resection.

To investigate the factors associated with the recovery process of elderly patients after degenerative lumbar scoliosis surgery. ⋯ The factors that affect postoperative recovery in elderly patients with degenerative lumbar scoliosis are age, American Society of Anesthesiologists grade, distal fusion level, presence of complications, and number of osteotomies.

Lumbar sympathetic neurolysis (LSN) is a treatment option for complex regional pain syndrome (CRPS). We examined whether LSN-related temperature changes are associated with clinical outcome and investigated relationships between the outcome of LSN and clinical variables in patients with CRPS-I. ⋯ LSN may be effective in some patients with CRPS, irrespective of temperature changes and temperature asymmetry pattern. A short duration of pain and concurrent cold intolerance significantly predict successful LSN.
