An animal study with immature sheep to evaluate the effects of a multisegment growth guidance rod (MSGGR) on spine growth. ⋯ N/A.

The Shilla growth guidance technique has been developed to treat spinal deformities without the necessity of repeated operative lengthenings. The dual stainless steel rods are fixed to the corrected apex of the curve by pedicle screws with limited fusion about the apex. Vertebral growth occurs in a cephalad and caudad direction through extraperiosteally placed sliding pedicle screws. A retrospective review of patients treated with the Shilla growth guidance technique for early-onset spinal deformity was performed to study patients with >2-year follow-up and describe outcome parameters. ⋯ IV case series of therapeutic study investigating results of treatment.

We aimed to determine spinopelvic balance in 8-19-year-old-people in order to assess pelvic and spinal parameters in sagittal view. ⋯ Preoperation planning for spinal fusion surgeries via applying PI seems reasonable. Predicating "abnormal" to lordosis and kyphosis values alone without considering overall sagittal balance is incorrect. Mean of SS and TK in our population is slightly less than that in Caucasians.

Cross-sectional baseline data set on the sagittal standing posture of 1196 adolescents. ⋯ The orientation of gross body segments with respect to the gravity line seems superior to local spinopelvic features in terms of clinical importance, at least in the current pre-PHV cohort. Opportunities may exist for postural subgrouping strategies to begin with global alignment parameters in order to gain further insight into the relationship between sagittal alignment and the relative risk of developing spinal pain/seeking medical consultation for this pain.

Fusionless growth modulation is an attractive alternative to conventional treatments of idiopathic scoliosis. To date, fusionless devices achieve unilateral growth modulation by compressing the intervertebral disc. This study explores a device to control spinal alignment and vertebral morphology via growth modulation while excluding the disc in a porcine model. ⋯ The proposed intravertebral epiphyseal device, for the early treatment of progressive idiopathic scoliosis, demonstrated its feasibility by manipulating spinal alignment through the realization of local growth modulation exclusive of the intervertebral disc.
