Validation of a methodology for neuro-urological and lumbosacral stimulation studies in domestic pigs: a humanlike animal model.

J Neurosurg Spine 2019 Feb 15:1-11. Epub 2019 Feb 15.

7Neurosurgery, Pellegrin Hospital, Bordeaux, Nouvelle Aquitaine; and.

OBJECTIVESpinal cord injuries (SCIs) result in loss of movement and sensory feedback, but also organ dysfunction. Nearly all patients with complete SCI lose bladder control and are prone to kidney failure if intermittent catheterization is not performed. Electrical stimulation of sacral spinal roots was initially considered to be a promising approach for restoring continence and micturition control, but many patients are discouraged by the need for surgical deafferentation as it could lead to a loss of sensory functions and reflexes.

Odontoid cervical gout causing atlantoaxial instability: case report.

J Neurosurg Spine 2019 Jan 25:1-4. Epub 2019 Jan 25.

Departments of1Neurosurgery and.

The authors present a case report of a patient discovered to have a rotatory subluxation of the C1-2 joint and a large retroodontoid pannus with an enhancing lesion in the odontoid process eventually proving to be caused by gout. This patient represented a diagnostic conundrum as she had known prior diagnoses of not only gout but also sarcoidosis and possible rheumatoid arthritis, and was in the demographic range where concern for an oncological process cannot fully be ruled out. Because she presented with signs and symptoms of atlantoaxial instability, she required posterior stabilization to reduce the rotatory subluxation and to stabilize the C1-2 instability. Read More

OBJECTIVEThe method of artificial disc replacement (ADR) has been developed as an alternative treatment to fusion surgery after decompression for cervical degenerative disc disease (DDD) with radiculopathy. Preserving the motion of ADR devices aims to prevent immobilization side effects such as adjacent-segment pathology (ASP). However, long-term follow-up evaluations using MRI are needed to investigate if this intent is achieved. Read More

Clinical outcomes research in spine surgery: what are appropriate follow-up times?

J Neurosurg Spine 2018 Dec 21:1-8. Epub 2018 Dec 21.

1Department of Surgery, Vancouver General Hospital/University of British Columbia, Vancouver, British Columbia.

OBJECTIVEThere has been a generic dictum in spine and musculoskeletal clinical research that a minimum 2-year follow-up is necessary for patient-reported outcomes (PROs) to adequately assess the therapeutic effect of surgery; however, the rationale for this duration is not evidence based. The purpose of this study was to determine the follow-up time necessary to ensure that the effectiveness of a lumbar surgical intervention is adequately captured for three lumbar pathologies and three common PROs.METHODSUsing the different PROs of pain, physical function, and mental quality of life from the Canadian Spine Outcomes and Research Network (CSORN) prospective database, the authors assessed the time course to the recovery plateau following lumbar spine surgery for lumbar disc herniation, degenerative spondylolisthesis, and spinal stenosis.

Treatment of posttraumatic lumbar interspinous ligament calcification with partial resection of spinous processes and calcified interspinous ligaments: case report.

J Neurosurg Spine 2018 Dec 21:1-5. Epub 2018 Dec 21.

The authors report on the first surgical treatment for traumatic interspinous ligament calcification, with significant radiographic and symptomatic improvements at long-term follow-up. Heterotopic ossification occurs following traumatic injury but does not typically affect the interspinous ligaments. While these ligaments can calcify with age, this is rarely seen in patients younger than 50 years of age. Read More

Evaluation of a more ventral starting point for thoracic pedicle screws: higher maximal insertional arc and more medial and safer screw angulation.

J Neurosurg Spine 2018 Dec 14:1-7. Epub 2018 Dec 14.

1Department of Orthopedic Surgery, Columbia University Medical Center, The Spine Hospital at NewYork-Presbyterian/Allen, New York, New York.

OBJECTIVETo demonstrate that a more ventral starting point for thoracic pedicle screw insertion, produced by aggressively removing the dorsal transverse process bone down to the superior articular facet (SAF), results in a larger margin for error and more medial screw angulation compared to the traditional dorsal starting point (DSP). The margin for error will be quantified by the maximal insertional arc (MIA).METHODSThe study population included 10 consecutive operative patients with adult idiopathic scoliosis who underwent primary surgery.

Robot-assisted intravertebral augmentation corrects local kyphosis more effectively than a conventional fluoroscopy-guided technique.

J Neurosurg Spine 2018 Nov 1:1-7. Epub 2018 Nov 1.

OBJECTIVEIntravertebral augmentation (IVA) is a reliable minimally invasive technique for treating Magerl type A vertebral body fractures. However, poor correction of kyphotic angulation, the risk of cement leakage, and significant exposure to radiation (for the surgeon, the operating room staff, and the patient) remain significant issues. The authors conducted a study to assess the value of robot-assisted IVA (RA-IVA) for thoracolumbar vertebral body fractures. Read More
