Welcome to the Global Spine Congress 2018!

AOSpine invites you to the 7th Annual Global Spine Congress (GSC), which will take place in Singapore from 2-5 May, 2018.

The GSC - the only truly International Spine Congress of its kind - is one of the biggest gatherings for thousands of spine surgeons from all over the world. The congress provides an outstanding forum to exchange ideas, network with fellow spine professionals, and to learn about the latest research, techniques, and technologies in spine surgery.

Welcome to Journal of Spine Surgery (JSS)

Welcome to Journal of Spine Surgery (JSS), an Open-Access journal devoted to exploring many contemporary issues affecting spine surgery, patient care and the basic sciences that form the foundation of surgical management. The Journal of Spine Surgery is intended to be an international spine journal with an Australasian platform for the exchange of ideas, experiences, new findings and developments in the treatment and outcomes of spinal care.

Advantages and disadvantages of posterolateral approach for percutaneous endoscopic lumbar discectomy

Preoperative radiographic findings regarding the location and type of lumbar disc herniation (LDH). LDH is classified into 3 types according to the location of herniation on axial MRI: foraminal (A), extraforaminal (B), and combined (C). White arrowheads indicate herniated nucleus. The foraminal height (dotted line) and width (solid line) were calculated on sagittal view of preoperative CT (D).

The importance of loading the periphery of the vertebral endplate

The vertebrae were divided into two groups based on the type of mass produced implant (MPI) used in the testing. Group 1 used a 3D-printed titanium ALIF MPI (4WEB) (A); group 2 used PEEK ALIF MPI (K2M) (B). These MPI sizes were chosen based on the size of the 16 cadaveric vertebrae used in the study. An aluminum plate was also cut to match the profile of the largest vertebral endplate (C). This was done to ensure that the whole endplate, including the bony periphery, would be loaded for all specimens.

Pan-spinal infection: a case series and review of the literature

A 45-year-old male, with a past history of intravenous drug use (IVDU), chronic hepatitis C infection and alcoholism, was admitted for 2-week history of weakness and paraesthesia of bilateral lower limbs, with power of 4/5 (Medical Research Council–MRC grading) as well as both urinary and fecal incontinence. MRI full spine revealed extensive epidural abscess along the whole spinal canal.

Cervical spine immobilisation in the elderly population

Immobilization of the cervical spine is a cornerstone of spinal injury management. It is hypothesised that the increased thoracic kyphosis and loss of cervical lordosis seen in elderly patients may require alternative cervical immobilisation, compared with the ‘neutral position’. A) Preoperative CT scout film showing extended position of the C-spine with the gaze pointing upwards; (B) cervical spine CT sagittal midline image showing posterior displacement and angulation of the C2 fracture fragment in this position; (C) postoperative CT scout film showing slightly kyphosed chin-brow horizontal angle but a nearly horizontal gaze; (D) postoperative cervical spine CT sagittal midline image showing reduction of the fracture displacement in this position.

Effects of cement augmentation on the mechanical stability of multilevel spine after vertebral compression fracture

Three-centreline method for measuring intervertebral disc space. To measure the disc space, 2 straight lines were drawn from 4 landmarks, A-D, chosen as the lowermost corners of the vertebral bodies adjacent to the disc space being measured. Three additional lines dividing the first two lines equally were drawn. Disc space was measured at sites 1, 2 and 3 using ImageJ, and the 3 lengths were averaged and scaled to obtain an approximation of the intervertebral disc space height.

Journal of Spine Surgery (JSS) is Now Indexed in PubMed Central

It is our pleasure to share a good news that the Journal of Spine Surgery (JSS) is now officially accepted for inclusion in PubMed Central (PMC), an extensive and important biomedical online journal repository, and all articles published in JSS will be searchable in PMC as soon as the indexation process is finished. Consequently, authors publishing in JSS will enjoy maximum exposure of their research.

Single-level selective dorsal rhizotomy for spastic cerebral palsy

Intra-operative photomicrographs during a single-level selective dorsal rhizotomy (SDR) (A,B,C) and an electromyography (EMG) monitoring screen (D). In (A) the plane (solid arrow) between the dorsal sensory roots (white arrow) and the ventral motor roots, at the conus, is demonstrated. In (B) the dorsal roots have been identified and slung. Systematic stimulation of each of the divided rootlets is then carried out using dedicated Peacock probes (C). (D) shows a typical screenshot of a Grade IV response on the EMG monitoring screen; stimulation of the L5 nerve root (arrow) results in a diffuse bilateral EMG response.

Clinical presentation and surgical outcomes of an intramedullary C2 spinal cord cavernoma: a case report and review of the relevant literature

A 56-year-old male presented with sensory changes in his right hand which progressed over a period of weeks to bilateral sensory changes in the upper and lower limbs, gait imbalance, urinary and faecal incontinence and loss of temperature perception. Immediately postoperatively, dense hemiparesis was noted on the right side, however, there was steady improvement in both motor and sensory function over the subsequent days in addition to a complete return of bladder and bowel function. Histopathology, consistent with spinal cord intramedullary cavernomas with hemorrhage, displayed areas of tissue with increased vascularity and characteristic thin walled blood vessels of various sizes.

Surgery for spinal tuberculosis: a multi-center experience of 582 cases

A 30-year-old female with spinal tuberculosis at the L3 vertebrae with paraplegia and 45° kyphosis. (A) Preoperative imaging demonstrated gross destruction of L3 vertebrae with spinal cord compression; (B) posterior decompression and stabilization by transpedicular screws and rods with posterior interbody fusion was performed; (C) follow-up imaging postoperatively demonstrated correction of kyphosis with radiological sign of gradual bone fusion (preoperative, 4-month, 12-month).
