Vertebral artery dissection following a posterior cervical foraminotomy with rhizolysis of the subaxial spine has not been described before. A 46-year-old lady underwent the procedure for a left C6 radiculopathy with a focal disc herniation with no intraoperative complications. Seven hours post-operatively, she developed a right homonymous hemianopia, thalamic dysphasia, gait and memory impairment. Imaging demonstrated an occlusion to the left vertebral artery from C7/T1 to C4 with a dissection flap noted at the inferior margin...

OBJECT: This study describes an experimental rabbit model that allows the reproduction of percutaneous operations that are used in patients with trigeminal neuralgia (TN). Attention was given to an exact anatomical description of the rabbit's middle cranial fossa as well as the establishment of conditions for a successful procedure. METHODS: Morphometric measurements were taken from 20 rabbit skulls and CT scans. The anatomy of the trigeminal nerve, as well as its surrounding structures, was assessed by bilateral dissection of 13 New Zealand white rabbits (NWR)...

The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for C1/C2 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including degenerative disc and facet disease when conservative methods are unsuccessful. However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology...

INTRODUCTION: Glycerol rhizolysis, thermocoagulation and balloon compression are well established in the treatment of trigeminal neuralgia. Despite this, very few direct comparisons between these procedures have been published. We aimed to compare the outcome profile of these 3 percutaneous procedures in a single center over a long follow-up period. METHODS: Over 19 years, 393 procedures were performed on 210 patients with trigeminal neuralgia. Patient records and telephone follow-up were used to determine demographic and operative details and surgical outcomes...

BACKGROUND: Zygapophysial joint arthrosis is a pathology related with axial lumbar pain. The most accepted treatment, after failure of medical management, is the thermal denervation of the medial branch. Nonetheless, the placement of the heat probe remains a challenge to surgeons, even when using the fluoroscope. Using a variation of Shealy's and Bogduk's original techniques, which includes ablation of the medial branch and the nerves present in the joint capsule, we hypothesize that we can obtain similar outcomes to those found in the literature...

INTRODUCTION: Trigeminal neuralgia is a sudden, unilateral, brief, stabbing, recurrent pain in the distribution of one or more branches of the fifth cranial nerve. Pain occurs in paroxysms, which can last from a few seconds to several minutes. The frequency of the paroxysms ranges from a few to hundreds of attacks a day. Periods of remission can last for months to years, but tend to shorten over time. The condition can impair activities of daily living and lead to depression. METHODS AND OUTCOMES: We conducted a systematic review and aimed to answer the following clinical question: What are the effects of ongoing treatments in people with trigeminal neuralgia? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review)...

A 78-year-old man with combined trigeminal and glossopharyngeal neuralgia underwent glycerol rhizolysis of the trigeminal ganglion. The treatment led to the immediate relief of both neuralgias. We discuss the potential mechanism of this unexpected therapeutic effect with reference to the pathophysiology of trigeminal and glossopharyngeal neuralgia.

In the Australian medical and paramedical fields considerable interest has been stirred by percutaneous rhizolysis, the procedure introduced here by Dr. W. E. Skyrme Rees, M.B., Ch.B., F.R.C.S. The technique itself comes under intensive scrutiny. In theory the technique is a "percutaneous bilateral section of the posterior primary rami", either lumbar or cervical.

Percutaneous retrogasserian glycerol rhizolysis, introduced in 1981, has become established in the management of trigeminal neuralgia secondary to multiple sclerosis and pontine infarction. More recently, this technique was established as safe and reliable in managing pain originating from the zygapophyseal joints, with successful relief of pain in 67% of patients treated for lower back pain. In this article, we report a case of complete paralysis of lumbar paravertebral muscle function caused by severe multifidus degeneration after 3-level lumbar rhizolysis...

Trigeminal neuralgia is a disorder associated with severe episodes of lancinating pain in the distribution of the trigeminal nerve. Previous reports indicate that 80-90% of cases are related to compression of the trigeminal nerve by an adjacent vessel. The majority of patients with trigeminal neuralgia eventually require surgical management in order to achieve remission of symptoms. Surgical options for management include ablative procedures (e.g., radiosurgery, percutaneous radiofrequency lesioning, balloon compression, glycerol rhizolysis, etc...

Trigeminal neuralgia (TN) is a neuropathic pain condition affecting the face. It has a significant impact on the quality of life and physical function of patients. Evidence suggests that the likely etiology is vascular compression of the trigeminal nerve leading to focal demyelination and aberrant neural discharge. Secondary causes such as multiple sclerosis or brain tumors can also produce symptomatic TN. Treatment must be individualized to each patient. Carbamazepine remains the drug of choice in the first-line treatment of TN...
