Accuracy of SPECT Scanning in Diagnosing Pseudarthrosis: A Prospective Study

A study to analyze the efficacy of SPECT in diagnosing pseudarthrosis after fusion.

Discography Summary: Section 1

The primary utility of discography is as a provocative clinical test for the evaluation of axial spinal pain.

Discography Summary: Section 2

Some believe that discography is necessary prior to fusion.

Discography: Technique

A review of approaches, complications, and study outcomes.

EBI® VueCath® System: Spinal Endoscopic Tool for Diagnosis and Treatment

EBI's VueCath system aids in the diagnosis of chronic low back pain and enables the pain management specialist to inject medications precisely into the spine.

Intradural Tumors: Intraoperative Monitoring

Intraoperative monitoring with motor evoked potentials (MEPs) is a direct motor tract monitoring technique.

Lumbar Discography

Several studies have confirmed the accuracy of discography as a radiologic test in demonstrating both disc herniations and disc degeneration.

Magnetic Resonance Neurography of Sciatic Nerve Following Crush Injury, and Correlation with Functional Deficit

Magnetic Resonance Neurography of Sciatic Nerve Following Crush Injury, and Correlation with Functional Deficit.

Novel Radiation-Free Assessment of Scoliosis and the Cobb Angle

The Ortelius800® is a new non-invasive radiation-free 3-D imaging system for the diagnosis and monitoring of scoliosis and other spinal deformities.

Pressure Controlled Discography

Psyiologic loading of the disc creates horizontal and vertical stresses within the nucleus, annulus and endplates of the disc.

Provocative Discography: Section 1

It is important to know the false positive and false negative rates associated with provocative discography.

Provocative Discography: Section 2

Psychological factors are important sources of false positive results with discography.

Provocative Discography: Section 3

The rates of false positive discography in select patients without low back complaints.

Provocative Discography: Section 4

The primary indication for provocative discography is to determine whether a patient with chronic spinal pain, who has failed aggressive efforts at conservative care, can be helped with spinal fusion.

Radiographs, CT Scans, Myelography, MRI, Bone Scan, Electrodiagnostic Tests and Discography

Plain radiographs of the spine can identify deformity, most fractures, destructive lesions, spondylolisthesis, and spondolytic changes but are less sensitive for soft tissues.
