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: For one-level ACDF, the anchored cage with screws has some advantage compared to the stand-alone PEEK cage in avoiding dysphagia and restoring disc space height and cervical lordosis. We suggest the anchored spacer may be a good substitute for the stand-alone cage in one-level ACDF. Level of Evidence: Level II

Conclusions: Even with the absence of subjective urinary symptoms, subclinical urologic impairments can be observed in a significant number of patients with ISC. An abnormal UDS finding can be a sign of underlying spinal cord tethering in a patient with ISC who is a candidate for corrective spine surgery even though it is an independent variant and is not exclusive to candidates for surgery. This finding has high clinical utility for neuro- and ortho-spine surgeons who aim to correct scoliosis (OR, 4.2; p =0.009). PMID: 32066207 [PubMed - as supplied by publisher]

ConclusionAIS patients showed more slender spines than the asymptomatic population. Analysis of wedging suggests that lower junctional discs and apex vertebra could be locations of mechanical instability. Numerical simulation and longitudinal clinical follow-up of patients could clarify the impact of wedging, slenderness and growth on the biomechanics of scoliosis progression.Graphic abstractThese slides can be retrieved under Electronic Supplementary Material.

CONCLUSIONS: Cumulative radiation dose during scoliosis treatment varies substantially depending on radiographic follow-up protocol, intraoperative and ancillary imaging. By using low-dose X-ray systems in combination with a low-dose protocol for intraoperative navigation, it is possible to keep exposure to patients at a minimum while still providing optimal care. FUNDING: none. TRIAL REGISTRATION: not relevant. PMID: 32053488 [PubMed - in process]

Abstract OBJECTIVE: Achieving fusion at the lumbosacral junction poses many technical challenges. No data exist in the literature comparing radiographic or clinical outcomes between the different surgical techniques of transsacral fixation (TSF) with rods and transforaminal lumbar interbody fusion (TLIF) in conjunction with iliac fixation. The purpose of this study was to compare the clinical outcomes and radiographic fusions of TSF to TLIF in patients with adult spinal deformity undergoing long fusions across the lumbosacral junction. METHODS: Patients with primary adult spinal deformity who underwent long f...

This study aimed to assess the accuracy of smartphone-aided diagnosis of scoliosis by a trained nurse compared with scoliometer-based diagnosis by a spine surgeon. Summary of Background Data. Many assessments have been developed to estimate the reliability of smartphone-aided measurements in diagnosing scoliosis. However, clinical studies assessing the accuracy of smartphone-aided diagnosis with radiographs or scoliometers are scarce. Methods. A total of 2702 grade 7 students (mean age 13.56 yrs, range 13–15) at 10 middle schools were first screened with a smartphone by a trained nurse from the orthopedics depa...

Study Design: A retrospective analysis of a prospectively collected database was performed. Objective: The purpose of this study is to compare 3-dimensional correction associated with the anterior release (AR) and contemporary posterior instrumentation versus posterior-only surgery. Summary of Background Data: The role of AR as a tool in the treatment of adolescent idiopathic scoliosis (AIS) has seen a decline with the popularization of thoracic pedicle screw instrumentation. Methods: Five surgeons were queried for all surgical thoracic AIS cases from 2003 to 2010 treated with thoracoscopic AR/fusion and contemp...

Background: Although studies have been published stating obese patients are less compliant with brace use, no objective studies measuring hours of daily brace wear have been performed to correlate brace wear and success with body mass index (BMI). The purpose of this study was to establish the relationship between BMI and brace compliance, and between BMI and progression to surgical magnitude of 50 degrees or more. Methods: A total of 175 adolescents were prescribed thoracolumbarsacral orthosis for the treatment of an adolescent idiopathic scoliosis and followed to completion of treatment. BMI was measured at brace pr...

Conclusions: A curve>40 degrees at SS7 is at high risk for progressing to a curve measuring>50 degrees or requiring surgery. Those with curves below this threshold still have potential to make clinically significant progression after skeletal maturity. Follow-up of patients beyond SS7 is essential for curves measuring>40 degrees. Reaching SS7 with a curve

Introduction: It is unclear what factors influence health-related quality of life (HRQOL) in neuromuscular scoliosis. The aim of this study was to evaluate which factors are associated with an improvement in an HRQOL after spinal fusion surgery for nonambulatory patients with cerebral palsy (CP). Methods: A total of 157 patients with nonambulatory CP (Gross Motor Function Classification System IV and V) with a minimum of 2-year follow-up after PSF were identified from a prospective multicenter registry. Radiographs and quality of life were evaluated preoperatively and 2 years postoperatively. Quality of life was evalu...
