Cement augmentation of pedicle screws is able to improve screw anchorage in osteoporotic vertebrae but is associated with a high complication rate. The goal of this study was to evaluate the impact of different cement volumes on pedicle screw fatigue strength. ⋯ Cement augmentation significantly increases pedicle screw stability. The benefit of augmentation on screw anchorage was not significantly affected by reducing the applied volume of cement from 3 ml to 1 ml. Considering the high risk of cement leakage during augmentation, we recommend the usage of a reduced volume of 1 ml bone cement for each pedicle screw.

To evaluate specific demographic and perioperative variables associated with higher inpatient pain scores following minimally invasive transforaminal lumbar interbody fusion (MIS TLIF). ⋯ The results of this study suggest that younger age, workers' compensation, elevated preoperative pain scores, and longer operative times are independently associated with greater inpatient pain following TLIF. Surgeons can use this information to better assess which patients may require additional pain control following TLIF. Patient expectations of postoperative outcomes in regard to pain and recovery may also be better managed. These slides can be retrieved under Electronic Supplementary Material. (paragraph).

The global alignment and proportion (GAP) score was recently developed to consider proportional analysis of spinopelvic alignment and has been indicated for setting surgical goals to decrease the prevalence of mechanical complications. The goal of this study was to clarify the limitations and problems with spinal corrective surgery with minimally invasive lateral lumbar interbody fusion (LLIF) without osteotomy using GAP score, and to establish a preoperative radiographical evaluation to understand the necessity for three-column osteotomy. ⋯ III.

The purpose of this study was to determine the incidence of spinal deformities in ambulant adults with cerebral palsy (CP) and spastic diplegia, more than 15 years after orthopaedic interval surgery approach (ISA) treatment, and its relationship to contextual factors, level of pain and physical status. ⋯ Adults with spastic diplegic CP who received their first orthopaedic intervention more than 15 years ago (based on ISA) showed similar incidence of spinal deformities as reported in the younger CP population, suggesting stability of spinal curvature into adulthood.

To investigate whether multi-shot diffusion-weighted imaging (ms-DWI) could be applied in diagnosis and quantitative evaluation of cervical spondylotic myelopathy (CSM). ⋯ The ms-DWI could be applied in diagnosis and quantitive assessment of CSM according to lADC and rADC. A new parameter, rADC, could be served as a diagnostic indice for CSM, which may quantitively reflect the severity of CSM. These slides can be retrieved under Electronic Supplementary Material.
