Surgeon Procedure Volume and Complication Rates in Anterior Cervical Discectomy and Fusions: Analysis of a National Longitudinal Database.
Retrospective study using the MarketScan longitudinal database (2006-2010). ⋯ We demonstrate a possible association between higher surgeon procedure volume and decreased post-operative complications following anterior cervical discectomy and fusion. There was no difference observed in need for revision surgery or readmission rates.

Spinopelvic Alignment by Different Surgical Methods in the Treatment of Degenerative Sagittal Imbalance of the Lumbar Spine.
Retrospective comparative study. ⋯ The PSO group was better than the ILF group in the correction of the LL and TK, but not with regards to the pelvic parameters. The ILF group was superior in the correction of the pelvic orientation as compared to the PSO group when the PI was constant after surgery. Ultimately, ILF effectively achieves better correction of the pelvic parameters (SS and PT).

Misplacement pattern of pedicle screws in pediatric patients with spinal deformity: a computed tomography study.
A retrospective study. ⋯ PSs insertion in pediatric patients with congenital scoliosis was less accurate than that in adult patients. However, the safety of placement was quite satisfactory. The possibility of pedicle breaching increased when placing PSs at deformed vertebra, on the apex of the curve, and in the thoracic spine, which reminds surgeons to be more cautious when placing PSs in these regions.

A porcine early-onset scoliosis model created using a posterior mini-invasive method: a pilot study.
An animal study. ⋯ A 3-dimensional rapidly progressive scoliosis model, that is closely approximate to human EOS, can be successfully created in pigs by unilaterally tethering the thoracolumbar spine and the ribcage. This model provides an equivalent EOS-like deformity and leaves adequate skeletal growth potential for biomechanical research as well as validation of fusionless scoliosis correction systems.

Clinical significance of postdecompression facet joint effusion after minimally invasive decompression for degenerative lumbar spinal stenosis.
A retrospective case series study. ⋯ The relatively high incidence of PDFE after MEDL suggests that injury to the integrity of facet joint is inevitable during decompression of the stenosis, even using minimally invasive techniques. However, the overall stability is well preserved with very rare progression of spondylolisthesis. Most patients with PDFE are asymptomatic. The prognosis of PDFE is very good. Spinal fusion is rarely indicated.
