Review Meta Analysis Comparative Study
Treatment of bracing for adolescent idiopathic scoliosis patients: a meta-analysis.
A meta-analysis was conducted to compare the efficacy and safety of bracing and other treatments in adolescent idiopathic scoliosis (AIS) patients. ⋯ The findings of this meta-analysis suggested that bracing is efficient and safe for the treatment of AIS.

Comparative Study
A comparative study of diffusion kurtosis imaging and T2* mapping in quantitative detection of lumbar intervertebral disk degeneration.
To assess the feasibility of diffusion kurtosis imaging (DKI) for diagnosing lumbar intervertebral disk degeneration (IDD) and to compare the potential of DKI and T2* mapping in the diagnosis of early IDD. ⋯ DKI can be used to assess human lumbar IDD. And DKI was more sensitive to the quantitative detection of early lumbar IDD than T2* mapping. These slides can be retrieved under Electronic Supplementary Material.

Previous studies of 4D rasterstereography show a high intra- and interday reliability. However, only few studies validate rasterstereography to conventional X-ray imaging. We utilized EOS X-ray imaging system (EOS Imaging, Paris, France) for accurate 3D spinal modeling and compared the results to parameters obtained by 4D rasterstereography. The aim of the present study was to validate 4D rasterstereography in patients with degenerative disk disease (DDD). ⋯ Our data suggest that rasterstereographic systems are no reliable substitute for X-ray-based imaging systems in patients with degenerative disk disease. EOS imaging was shown to provide reliable and accurate spinal modeling. Based on our results, rasterstereographic imaging should be used with caution for evaluating spinal and pelvic parameters in patients with DDD.

Randomized Controlled Trial
Cobb angle measurement with a conventional convex echography probe and a smartphone.
Serial X-rays are needed during the follow-up of adolescent idiopathic scoliosis. They are done every 6 or 3 months in cases of high risk of progression. Thanks to the advances in ultrasound techniques, deformity measurement systems free from ionizing radiations have been validated, although spinal surgeons did not use them routinely due to the need of special software. ⋯ An approximation of the Cobb angle measure is possible with ultrasound by using the transverse processes as reference. This is a very rapid and simple system for assessing the principal spinal deformity measure in young people, although it does not allow estimating the associated axial or sagittal rotation.

Case Reports
Rheumatoid arthritis-associated spinal neuroarthropathy with double-level isthmic spondylolisthesis.
To the best of our knowledge, there has been no report regarding rheumatoid arthritis associated with spinal neuroarthropathy and combined double-level isthmic spondylolisthesis. Here, we report a rare case of spinal neuroarthropathy with double-level isthmic spondylolisthesis in a rheumatoid arthritis (RA) patient. A 56-year-old female patient under medical treatment for RA during the last 13 years presented aggravating radiating pain to her right lower extremity and a limping gait developed 4 months ago. The disease activity of RA had remained low for a long time. Serial radiographs during last 8-year follow-up showed progressive dislocation at L4-L5 and L5-S1 with double-level isthmic spondylolisthesis and severe destructive status at the last follow-up. The patient underwent decompression and circumferential fusion with sacropelvic fixation and acceptable reduction was obtained. ⋯ A RA patient with double-level isthmic spondylolisthesis showed a progressive destructive lesion. In addition to clinical presentations, the imaging findings were very similar to ones of spinal neuroarthropathy. The authors conclude that this Grand Round case probably had SNA secondary to RA and that this, combined with two-level isthmic spondylolisthesis, resulted in her rapidly progressing destructive lumbar lesion.
