Lateral lumbar interbody fusion (LLIF) is a minimally-invasive approach to anterior spinal column fusion, deformity correction and indirect decompression of the lumbar spine. A rarely reported possible complication of the procedure is endplate fracture which has the potential for nerve root compression. Here we present a case of endplate fracture and nerve compression after stand-alone LLIF, its diagnosis, and its subsequent successful treatment with transforaminal endoscopic spine surgery. The case highlights the possible role for minimally invasive endoscopic surgery as a rescue procedure after fusion complication...

The pudendal nerve entrapment is an entity understudied by diagnosis imaging. Various causes are recognized in relation to difficult labors, rectal, perineal, urological and gynecological surgery, pelvic trauma fracture, bones tumors and compression by tumors or pelvic pseudotumors. Pudendal neuropathy should be clinically suspected, and confirmed by different methods such as electrofisiological testing: evoked potentials, terminal motor latency test and electromyogram, neuronal block and magnetic resonance imaging...

Compressive syndromes of the radial nerve have different presentations. There is no consensus on diagnostic and therapeutic methods. The aim of this review is to summarize such methods. Eletronic searches related terms, held in databases (1980-2016): Pubmed (via Medline), Lilacs (via Scielo) and Google Scholar. Through pre-defined protocol, we identified relevant studies. We excluded case reports. Aspects of diagnosis and treatment were synthesized for analysis and tables. Quantitative analyzes were followed by their dispersion variables...

RATIONALE: Plasma cell neoplasms are categorized by neoplastic proliferation of a single clone of plasma cells which produce a monoclonal immunoglobulin. Plasma cell neoplasms can present as a solitary plasmacytoma or as multiple myeloma. Both of them can progress to multiple myeloma. Once a diagnosis of plasmacytoma has been made, thorough examinations should be carried out for identifying the disease entity. PATIENT CONCERNS AND DIAGNOSES: Herein, we describe an extraordinary rare case of multiple myeloma with initial presentation of a left sphenoid neoplasm resulting in left-sided headache and rapid deterioration of visual acuity...

BACKGROUND: Idiopathic trigeminal neuralgia (TN) is caused by neurovascular compression and is often related to morphological changes in the trigeminal nerve. The aim of this study was to quantitatively measure atrophic changes of trigeminal nerves in patients with TN, and to further investigate whether nerve atrophy affected the efficacy of microvascular decompression (MVD). METHODS: We conducted a prospective case-control study of 60 consecutive patients with TN and 30 sex- and age-matched healthy controls...

AIM: To assess the correlation of lateral recess stenosis (LRS) of lumbar segments L4/5 and L5/S1 and the Oswestry Disability Index (ODI). METHODS: Nine hundred and twenty-seven patients with history of low back pain were included in this uncontrolled study. On magnetic resonance images (MRI) the lateral recesses (LR) at lumbar levels L4/5 and L5/S1 were evaluated and each nerve root was classified into a 4-point grading scale (Grade 0-3) as normal, not deviated, deviated or compressed...

A case of coexistent glossopharyngeal neuralgia and hemifacial spasm was treated by transposition of the vertebral artery. A 60-year-old man was referred to our hospital due to pain in the left posterior part of the tongue that was difficult to control with oral medication at a local hospital. The diagnosis was left glossopharyngeal neuralgia based on the symptoms, imaging findings, and lidocaine test results. Moreover, the patient had left hemifacial spasm. Microvascular decompression was performed, which confirmed that the vertebral artery was compressing the lower cranial nerve and the posterior inferior cerebellar artery was compressing the root exit zone of the facial nerve...

OBJECTIVE: In symptomatic unruptured intracranial aneurysms (UIA), data on long-term functional outcome are sparse in the literature, even in the light of modern interdisciplinary treatment decisions. We therefore analysed our in-house database for prognostic factors and long-term outcome of neurological symptoms after microsurgical/endovascular treatment. METHODS: Patients treated between 2000 and 2016 after interdisciplinary vascular board decision were included...

Hisaaki Tabuchi, Bernhard Laback
The cochlear phase response is often estimated by measuring masking of a tonal target by harmonic complexes with various phase curvatures. Maskers yielding most modulated internal envelope representations after passing the cochlear filter are thought to produce minimum masking, with fast-acting cochlear compression as the main contributor to that effect. Thus, in hearing-impaired (HI) listeners, reduced cochlear compression hampers estimation of the phase response using the masking method. This study proposes an alternative approach, based on the effect of the envelope modulation strength on the sensitivity to interaural time differences (ITDs)...

Osteogenesis imperfecta (OI) is a bone disorder that can lead to skull base deformities such as basilar invagination, which can cause compression of cranial nerves, including the trigeminal nerve. Trigeminal neuralgia in such cases remains a challenge, given distorted anatomy and deformities. We present an alternative option, consisting in cannulation of the foramen ovale and classical percutaneous treatment. Percutaneous balloon microcompression was performed in a 28 year-old woman with OI and severe trigeminal neuralgia using computed tomography (CT) and radiographic-guided cannulation of the Gasserian ganglion without neuronavigation or stereotactic devices...

Patients with hand muscular atrophy due to damage of the ulnar nerve could be stigmatized for their appearance. Unsatisfactory results in the attempt to correct the atrophy are reported in the literature. Fat grafting is an autologous and easily obtainable graft, antigenic response is very unlikely, it does not require any special material, and the procedure has a low cost. The technique of autologous fat grafting by using fat block, to remodel the first interdigital space, is useful and safe in correcting muscle atrophy of the first interdigital space caused by the injury of the ulnar nerve...

RATIONALE: Suprascapular nerve compression is a rare but important entity that is often missed in clinical practice. Nerve dysfunction caused by an intraosseous ganglion of the glenoid is extremely rare, to the best of our knowledge, only 1 case of suprascapular nerve entrapment due to an intraosseous ganglion cyst has been reported previously in the published literature. PATIENT CONCERNS: We report a 61-year-old woman who had complained right shoulder pain that lasted over 3 years which was exacerbated by overhead activities...

It is not common for an isolated visual symptom to be the first indication of an aneurysm compressing the optic nerve. The compression can lead to blindness, and a recovery from the blindness is rare. We report a female with a left painless optic neuropathy caused by an unruptured anterior cerebral artery aneurysm. The patient had a temporal hemianopic visual field defect, which progressed to blindness in the left eye, while the right visual function was not affected. A coil embolization of the aneurysm completely restored her visual acuity to 20/20...

Pneumorachis, or intraspinal air, can be a rare result of blunt thoracic trauma. We report the case of a 40-year-old man with multiple injuries and pneumorachis associated with persistent tachycardia. As factors that increase heart rate were gradually ruled out, intraspinal air was considered the potential culprit. Computed tomography revealed intraspinal air at the thoracic level, which possibly promoted cardiac arrhythmogenesis. Air may transiently compress the preganglionic cardiac sympathetic nerves and increase sympathetic output to the heart...

Sarah K B Bick, Emad N Eskandar
Trigeminal neuralgia is characterized by severe, episodic pain in the trigeminal nerve distribution. Medical therapy is the first line treatment. For patients with refractory pain, a variety of procedures including microvascular decompression, percutaneous radiofrequency rhizotomy, percutaneous glycerol rhizotomy, percutaneous balloon compression, and stereotactic radiosurgery are available. We review the literature and suggest that microvascular decompression remains the gold standard operative therapy. For patients with recurrent pain or who are poor operative candidates, percutaneous radiofrequency rhizotomy offers the best pain response rates and has the advantage of being able to selectively target affected trigeminal divisions...

Skeletal-related events in patients with metastatic bone disease include intractable severe pain, pathologic fracture, spinal cord and nerve compression, hypercalcemia and bone marrow aplasia. In patients with breast cancer, the skeleton is the most frequent site for metastases. Treatment options for metastatic bone disease in these patients include bisphosphonates, chemotherapeutic agents, opioids, hormonal therapy, minimally invasive/interventional and surgical techniques. Interventional oncology techniques for breast cancer patients with bone metastases include diagnostic (biopsy) and therapeutic (palliative and curative) approaches...

In addition to the more common carpal tunnel and cubital tunnel syndromes, orthopaedic surgeons must recognize and manage other potential sites of peripheral nerve compression. The distal ulnar nerve may become compressed as it travels through the wrist, which is known as ulnar tunnel or Guyon canal syndrome. The posterior interosseous nerve may become entrapped in the proximal forearm as it travels through the radial tunnel, which results in a pain syndrome without motor weakness. The median nerve may become entrapped in the proximal forearm, which can result in a variety of symptoms...

Carpal tunnel syndrome (CTS) is a focal compressive neuropathy of the median nerve at the level of the wrist. CTS is the most common type of compressive neuropathy that occurs in the upper extremity. Typically, patients with CTS have paresthesia, pain, and numbness in the radial three and one-half digits. Nighttime symptoms are more common earlier in the disease process, with daytime symptoms becoming more frequent as CTS progresses. Electrodiagnostic studies may be performed to confirm a diagnosis of CTS or to obtain a baseline before surgical treatment; however, electrodiagnostic studies may be normal in a subset of patients who have CTS...

A 30-year-old man presented with recurrent hematomas and tingling in his left leg, caused by a large femoral neck osteochondroma that induced multiple muscle ruptures and compressed the ischiadic nerve. There were no radiological signs of malignant transformation and symptoms disappeared without intervention. Hence, we chose a 'wait and see' approach instead of surgical removal of the osteochondroma.
