Different acute behaviors of pelvic incidence after long fusion to sacrum between elderly patients with severe and minor sagittal deformity: a retrospective radiographic study on 102 cases

ConclusionPI spontaneously increases in elderly ASD patients with severe sagittal deformity after long fusion to sacrum, while is relative invariable in those with minor sagittal deformity. Variation in PI could be considered as a secondary change compensating for the spinal sagittal malalignment under long spinal fusion in elderly patients.

Authors: Kobayashi K, Ando K, Nakashima H, Machino M, Morozumi M, Kanbara S, Ito S, Inoue T, Yamaguchi H, Mishima K, Ishiguro N, Imagama S Abstract Study Design: Single-center retrospective study in pediatric patients. Purpose: The purpose of the study was to investigate the effects of the presence and severity of leg-length discrepancy (LLD) on scoliosis in children. Overview of Literature: LLD is a common orthopedic problem that can result in standing imbalance, low back pain, and stress fractures. It may cause structural changes in the spine over time, but the exact effect of LLD on scoliosis is unknown....

This study aimed to evaluate the improvement and maintenance of cervical lordosis and sagittal alignment after VBSO. METHODS: A total of 65 patients were included; 34 patients had undergone VBSO, and 31 had undergone anterior cervical corpectomy and fusion (ACCF). Preoperative, postoperative, and final follow-up radiographs were used to evaluate the improvements in cervical lordosis and sagittal alignment after VBSO. C0-2 lordosis, C2-7 lordosis, segmental lordosis, C2-7 sagittal vertical axis (SVA), T1 slope, thoracic kyphosis, lumbar lordosis, sacral slope, pelvic tilt, and Japanese Orthopaedic Association scores we...

Conclusion. The procedure showed favorable initial stability and maintained favorable clinical outcomes in patients with CP. More than 90% of the patients showed disc degeneration on either side. The rate of proximal adjacent segment degeneration was higher than that of distal segments with or without symptoms at the>10-year follow-up. Level of Evidence: 4

ConclusionWe found a lower HRQOL in adult patients with SK 39  years after diagnosis regarding SRS-22r domains pain and self-image, and a tendency toward lower overall HRQOL compared with a background population. The location of the SK apex did not seem to have an overall impact on HRQOL. There was no difference in pelvic parameters in the two groups and no d ifference in pulmonary function.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

ConclusionsThe annual incidence of AVF in a general population with prevalent VF was 6.1%/year. In addition, lower BMD at the femoral neck and PI-LL> 20 ° were risk factors for AVF.

ConclusionCurve progression can be predicted by the underlying vertebral abnormalities. However, it cannot predict cord and other organ-system anomalies. Thus, all patients with congenital scoliosis must undergo MRI of the spine, electro- and echocardiography and ultrasonography of the abdomen to detect occult abnormalities and optimize the patient prior to deformity correction.

Conclusions: Prophylactic neurosurgery may be beneficial for decreasing the risk of correction surgery in SMS patients with large syrinx (S/C ratio >0.7). After the intervention of syrinx prior to scoliosis correction, SMS patients with large syrinx could obtain similar clinical and radiographic outcomes of treatment with pedicle-screw-based spinal instrumentation and fusion compared to the patients with small syrinx.

CONCLUSIONS: PSO can provide acceptable radiographic outcomes for the correction of thoracolumbar kyphosis in patients with AS. However, a high incidence of surgery-related complications related to mechanical failure and surgical technique can develop. Thorough radiographic investigation before and during surgery is needed to determine whether complete ossification occurs along the anterior and posterior longitudinal ligaments of the spine.

AbstractPurposeSurgical correction for AIS has evolved from all hooks to hybrids or all screw constructs. Limited literature exists reporting outcomes using PHDS for posterior spinal fusion (PSF). This is the largest  series in evaluating results of PHDS technique.MethodsA retrospective review of consecutive AIS patients undergoing PSF by a single surgeon between 2006 and 2015 was performed. All eligible patients met a minimum 2-year follow-up. Patient demographics and radiographical parameters (radiographic shoulder height (RSH), T1 tilt, clavicle angle) at baseline, 6-week and 2-year post-operation were recorded. Th...

We report a case of double-level lumbar spondylolysis at L4 and L5 that was successfully treated with the double "smiley face" rod method. A healthy 29-year-old man who presented with a 6-year history of chronic low back pain was referred to us for surgical treatment. Plain radiographs and computed tomography of the lumbar spine revealed bilateral pars defects at L4 and L5 without slip or scoliosis. The patient underwent direct repair of the pars defects using the double smiley face rod method at L4 and L5. There were no intraoperative or postoperative complications, and the patient had improved clinically by 1 y...
