Differences of lumbopelvic sagittal parameters among community-dwelling middle-age and elderly individuals: Relations with locomotor physical function

This study aims to establish radiographic parameters of lumbopelvic sagittal alignment, gender related differences, and age-related changes in a middle-aged community, to investigate whether age-related changes of lumbopelvic alignment reflect the risk of locomotive syndrome (LS). This study included 448 healthy Japanese volunteers who attended a basic health checkup supported by the local government. The subjects (184 males and 264 females, mean age: 62.7 years) were grouped according to their age by decade. Sagittal lumbopelvic parameters were collected by lateral spine radiographs including lumbar lordosis (L1–S1, LL), lower lumbar lordosis (L4–S1, LLL), pelvic incidence (PI), pelvic tilt (PT) and sacral slope (SS). The three tests (stand-up test, two-step test, and 25-question geriatric locomotive function scale [GLFS-25]) composing the LS risk test were performed. LL was significantly lower in males than in the females. A significant decrease of LL and LLL was observed from 60 s to 70 s in the females. PI did not markedly change with aging in either gender but was lower in males. A remarkable increase of PT was seen from 60 s to 70 s in the females. SS did not markedly change with aging and was lower in males in all decades. The prevalence of LS risk in males and females increased gradually with age and was greater in females in any decade. 70 s females with LS risk had significantly lower LL and higher PT compared to them withou...

Conclusions: Five years following “graduation” from growing surgery for early onset scoliosis, there is progression of curve magnitude in both the coronal and sagittal planes up to 2 years, with no further progression at 5 years. A total of 21% of patients undergo at least 1 revision surgery, and average time to revision surgery is over 2 years from last planned surgery. Risk of revision surgery was higher in patients who underwent a spinal fusion as their definitive treatment strategy. Level Evidence: Level III—retrospective comparative. Type of Evidence: Therapeutic.

Conclusions: TK on intraoperative prone radiographs during PSFI for SK should match the standing TK ∼6 weeks later. Intraoperative prone LL only slightly increases on early standing radiographs. Assuming a routine postoperative course, intraoperative radiographs slightly underestimate TK (by 3 degrees) and LL (by 8 degrees) on>2-year standing radiographs. These parameters (TK, LL, UIV-LIV) are visualized during surgery and should be used in future studies to predict long-term outcomes. Level of Evidence: Level IV—retrospective study.

Conclusions: This study demonstrates that there is minimal error due to image acquisition and measurement when using a biplanar slot scanner. Biplanar slot scanning technology tended to underestimate the size of the marker; however, the least accurate measurements only erred by 1.5% from the true length. This indicates that unlike traditional radiographs the sources of error in biplanar slot scanning images are not due to parallax and are likely due to patient-specific factors and rather than the technology itself.

Conclusions. Pelvic retroversion and increased translation of L3 from the central sacral line on the early postoperative radiograph were associated with late L3-4 disc wedging in AIS fusions to L3. Careful surgical planning and correction of sagittal alignment are imperative to ensure the long-term outcomes. Level of Evidence: 4

AbstractPurposeL5 pedicle subtraction osteotomy (PSO) is a demanding technique; thus, PSOs are usually performed at the L3/L4 level to correct the lack of lumbar lordosis. Mid- to long-term improvements in clinical outcomes after L5 PSO are unknown. We aimed to determine the efficacy and safety of L5 PSO for rigid kyphosis deformities.MethodsWe retrospectively reviewed the records of 57 patients with a rigid kyphosis deformity (mean age: 68  years) who underwent extensive corrective surgery incorporating PSO with a >  2-year follow-up. Radiographic parameters, postoperative complication rates, and the...

Seizure disorder in cerebral palsy (CP) has been described as a risk factor for postoperative complications after posterior spinal fusion. However, the effect of seizures on the maintenance of curve correction has not been reported. The aim of this study is to investigate associations between seizure history and maintenance of curve correction after posterior spinal fusion in children with CP. We analyzed records of 201 children with CP who underwent posterior spinal fusion with two-year follow-up. Patients were classified as having no seizures (31%); controlled seizures (54%); or poorly controlled seizures (PCS, 15%). Per...

The purpose of this study was to assess the surgical outcomes of posterior vertebral column resection (PVCR) with short-segment fusion for pediatric patients with congenital kyphoscoliosis (CKS). The medical records of 12 consecutive pediatric patients with CKS due to hemivertebrae located in thoracolumbar and lumbar area that had undergone PVCR and presented for follow-up at a minimum of 2 years were retrospectively reviewed. The mean follow-up period was 56.2 months, and the mean age at the surgery was 9.2 years. We evaluated radiographic parameters using plain radiographs, and evaluated segmental co...

The purpose of this retrospective study was to determine the most appropriate distal fusion level in terms of clinical results and radiological changes in Lenke 3C adolescent idiopathic scoliosis (AIS). Between June 2010 and May 2014, a total of 90 consecutive patients who underwent surgery for Lenke 3C AIS were divided into three groups as L2, L3, and L4 according to the fusion levels and compared in terms of functional and radiological outcomes. Patients were evaluated with Scoliosis Research Society 22 (SRS 22) and the Oswestry disability index (ODI) at the final follow-up. Preoperative standard posteroanterior and late...

Conclusion. Although groups showed no significant differences in clinical outcomes, cervical alignment worsened after surgery in the LAMP and PDF groups. Within the PDF group, lower CL was an independent risk factor for poor recovery. Therefore, the indications for PDF in DCM patients with preoperative kyphotic alignment should be carefully considered. Level of Evidence: 3
