Systematic review./r/nThis work aimed to compare the Hounsfield units (HU) value obtained from computed tomography and the t score of dual-energy x-ray absorptiometry (DXA) in the prediction of the lumbar spine bone mineral density (BMD)./r/nSeveral reports have found a correlation between HU and […]

A 51-year-old lady with multiple comorbidities presented with T11 spondylolysis in association with thoracic stenosis and myelopathy. Our patient underwent T11-T12 laminectomy, T10-L1 posterior instrumented stabilization, and T11-T12 transforaminal interbody fusion. She had a good neurological […]

We present a case of ankylosing spondylitis with sagittal imbalance and having a suspicious Andersson lesion (AL) on magnetic resonance imaging (MRI) at D12-L1. The segment did not reveal any potential mobility on erect radiographs and supine MRI. L2 pedicle subtraction osteotomy was planned. […]

We report a rare case of a right-sided L4-5 facet osteoid osteoma in a 11-year-old female who presented with lower extremity pain, contractures, and gait disturbance in the setting of failed radiofrequency ablation. After open excision and single-level posterolateral fusion with instrumentation, […]

Cervical spine surgeries for degenerative conditions are rapidly increasing. Cervical post-surgery syndrome consisting of chronic pain, adjacent segment disease, recurrent disc herniation, facet joint pain, and/or epidural scarring is common. Repeat surgery is regularly recommended, though patients […]

Rheumatoid arthritis (RA) can cause deformity in particularly the craniocervical but also in the lower cervical region./r/nThe aim of this study is to give an overview of current literature on the association of disease activity score (DAS) and the prevalence and progression of rheumatoid […]

There exists sparse literature on Gunshot injuries (GSI) to the pediatric spine, its natural course, management protocols and outcomes following surgical intervention. Here, we present a projectile injury to the paediatric lumbar spine without any osseous disruption in a 5-year-old child requiring […]

Jian Cao (left) and Zhen Liu (right) Dietary vitamin D supplementation can potentially offer a benefit to those with adolescent idiopathic scoliosis (AIS), according to new research which found that a significantly higher occurrence and severity of scoliosis induced by a vitamin D deficient diet […]

Lumbar interbody fusion (LIF) is an established surgical intervention for patients with leg and back pain secondary to disc herniation or degeneration. Interbody fusion involves removal of the herniated or degenerated disc and insertion of interbody devices with bone grafts into the remaining […]

Epidural Abscesses at Spinal Cord Level: Fight or Flight? – Chris Kepler, M.D.

This paper describes a unique case-the first case of multiple fractures of the thoracic vertebrae caused by a low-voltage electric shock./r/nA 22-year-old male patient was diagnosed with compression fractures of Th2-Th6 caused by a muscle spasm resulting from an electric shock. The patient was […]

Selection of anatomic region of spine for decompression in patients with symptomatic tandem spinal stenosis (TSS) remains a challenge due to the confusing clinical presentation as well as uncertain evidence. A systematic review and meta-analysis of observational studies were conducted to compare […]

Unlike tandem stenosis of the cervical and lumbar spine, tandem cervical and thoracic stenosis (TCTS) of the spine is less common, and the approach and order of intervention are controversial. We aim to review the literature to evaluate the incidence and interventions for patients with cervical and […]

Revision for Non Union in Adult Spinal Deformity - Vincent Arlet, M.D.

Overground powered lower limb exoskeletons (EXOs) have proven to be valid devices in gait rehabilitation in individuals with spinal cord injury (SCI). Although several articles have reported the effects of EXOs in these individuals, the few reviews available focused on specific domains, mainly […]

To review the effect of tumor necrosis factor-alpha inhibitor (TNFi) therapies on radiographic progression in ankylosing spondylitis (AS) patients as evaluated by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Pubmed, MEDLINE, EMBASE, and the Cochrane Library databases were […]

The technique of posterior pedicle screw fixation has already been widely applied in the treatment of upper thoracic spinal tuberculosis. However, lesions of tuberculosis directly invade the vertebrae and surrounding soft tissues, which increases the risk of esophageal perforation induced by the […]

Dermal sinus tracts (DSTs) of the cervical and thoracic spine are extremely rare, particularly in adult patients because diagnosis is typically made in the early stage after birth by pediatricians.
