Reliability analysis for digital adolescent idiopathic scoliosis measurements.
Analysis of adolescent idiopathic scoliosis (AIS) requires a thorough clinical and radiographic evaluation to completely assess the three-dimensional deformity. Recently, these radiographic parameters have been analyzed for reliability and reproducibility following manual measurements; however, most of these parameters have not been analyzed with regard to digital measurements. The purpose of this study is to determine the intra- and interobserver reliability of common scoliosis radiographic parameters using a digital software measurement program. ⋯ Most common radiographic parameters for AIS assessment demonstrated good or excellent reliability for digital measurement and can be recommended for routine clinical and academic use. Preoperative assessments and coronal measures may be more reliable than postoperative and sagittal measurements. The reliability of digital measurements will be increasingly important as digital radiographic viewing becomes commonplace.

Case ReportsDiscography-induced acute lumbar disc herniation: a report of five cases.
The reported complication rate of provocative lumbar discography is low, ranging from 0-2.5%. We report five cases of acute lumbar disc herniation precipitated by discography, a previously unreported complication. The cases reported comprise of four men and one woman with ages ranging from 23-45 years. ⋯ In each case the patients' symptoms failed to resolve necessitating surgical intervention in all cases. In conclusion, annular deficiency is an obvious predisposing factor to discogram related disc herniation. New onset or a persistent exacerbation of radicular symptoms following provocative discography merits further investigation.

Clinical TrialMicrosurgical posterior herniotomy with en bloc laminoplasty: alternative method for treating cervical disc herniation.
At the present time, the anterior cervical discectomy and fusion procedure is widely accepted for treating cervical disc herniation. Recently, however, several authors have reported new disease due to degeneration of an adjacent segment. On the other hand, posterior discectomy, which can preserve mobility at the affected disc level, has been considered risky and technically difficult, especially for central or paracentral disc herniation. We are performing a new surgical technique, microsurgical posterior herniotomy with en bloc laminoplasty, for patients with myelopathy and radiculomyelopathy caused by cervical disc herniation. ⋯ This technique was safe and effective. Radiographically, the range of motion in the cervical spine and at the affected disc levels was preserved. In the future, this surgical procedure can become an alternative method for cervical disc herniation treatment.

Case ReportsResidual neck pain after traumatic spondylolisthesis of the axis.
Most patients with traumatic spondylolisthesis of the axis are treated nonsurgically. Some patients do not develop symptoms, but others experience strong and persistent neck pain. To clarify the factor that plays a major role in residual neck pain after this fracture, we reviewed nine patients who underwent conservative treatment. ⋯ Injury on the inferior articular surface of the axis may disturb spontaneous healing of C2-C3 subluxation and cause residual neck pain. It is necessary to assess the presence of injury to the inferior facet bilaterally with plain or computed tomograms.

Case ReportsIntradural migration of broken IDET catheter causing a radiculopathy.
This case report describes the migration of a broken intradiscal electrothermal therapy catheter tip from the disc space into the thecal sac, leading to a radiculopathy that improved after removing the catheter.
