Health-related quality of life in children and adolescent with different types of scoliosis: A cross-sectional study

Distribution of scoliosis in 2.22 million adolescents in mainland China: A population-wide analysis

Background

The characteristics of scoliosis afflicting school children and adolescents in mainland China are still unclear. Therefore, we conducted a systematic review to estimate scoliosis's prevalence and characterise its distribution in China.

Methods

We screened PubMed, Scopus, WanFang, China National Knowledge Infrastructure, National Science and Technology Library, and WeiPu databases for mainland China articles published between 1 January 1980 and 31 October 2022. Among them, we identified population-wide scoliosis studies in school children and adolescents. The main outcomes were the positive rate of primary screening and the prevalence of final screening. Primary screening mainly included general examination with/without the forward bending test in school. The final screening entailed clinical diagnosis by Röntgen radiation in a hospital (based on primary screening). A meta-analysis of scoliosis distribution by gender was performed to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). Further, we analysed the distributions of scoliosis by age, region, aetiological type, and severity of curvature, in addition to the correlation between its prevalence and altitude or latitude.

Results

77 studies with 2 224 320 participants were included. The positive rate through primary screening was 3.97%, whereas the prevalence of scoliosis at final screening was 1.20%. Analysing the data revealed a higher prevalence of scoliosis in girls (OR = 1.57; 95% CI = 1.38-1.81). The age-wise peak rate of scoliosis was 15-16 years (1.07%) in boys and 13-14 years (1.42%) in girls. The mean prevalence of scoliosis was 1.07% in the western region, 1.54% in the central, and 1.35% in the eastern. Scoliosis prevalence was not correlated with either altitude or latitude. The prevalence of idiopathic and congenital scoliosis was 1.18 and 0.03%. Among all subjects with scoliosis, 79.10 and 16.80% had mild and medium disease severity.

Conclusions

According to this comprehensive study using data sets of scoliosis in adolescents across mainland China, the mean prevalence of scoliosis is 1.20%, yet 1.57 times higher in girls than boys, and is most prevalent in the middle region. Overall, scoliosis in adolescents could pose a burden to public health in mainland China.

Hip reduction surgery versus scoliosis correction in non-ambulant neuromuscular patients: which surgery is the first step?

PURPOSE

Children and young adults with neuromuscular disorders have a high incidence of both spine and hip deformities. The aim of this study was to evaluate the outcome of either primary scoliosis or hip surgery in children and young adults with neuromuscular disorders.

METHODS

A retrospective study was conducted on all children and young adults with neuromuscular-related synchronous hip subluxation/dislocation and scoliosis undergoing hip or scoliosis surgery in our institution between 2012 and 2021 with a minimum follow-up of 24 months. Demographic and operative data were collected; radiological parameters were measured preoperatively and postoperatively at final follow-up.

RESULTS

Forty neuromuscular patients with synchronous hip displacement and scoliosis were included. Twenty patients with an average age of10.2 years had hip correction surgery performed primarily, with a mean follow-up of 54.9 (24-96) months. The other 20 patients with an average age of 12.4 years had scoliosis correction first, with a mean follow-up of 40 (24-60) months. In the "Hip first" group, pelvic obliquity, hip MP and Cobb angle were 16.8°, 71%, and 49°, respectively. At final follow-up, the mean pelvic obliquity and Cobb angles significantly progressed to 27.2° (p = 0.003) and 82.2° (p = 0.001), respectively. Eighteen patients (90%) required scoliosis correction after the hip surgery. In the "Scoliosis first" group, the mean pelvic obliquity, hip MP and Cobb angle were 21.2°, 49% and 65.5°, respectively. At final follow-up, both pelvic obliquity and Cobb angle significantly improved to 8.44° (p = 0.002) and 23.4° (p = 0.001), respectively. In 11/20 (55%) patients, the hip MP had significantly increased following the spinal surgery to 62% (p = 0.001), but only 5/20 (25%) patients underwent hip surgery after scoliosis correction.

CONCLUSION

In neuromuscular patients presenting with synchronous hip displacement and scoliosis deformity, corrective scoliosis surgery is associated with a significant correction of pelvic obliquity and lower rates of secondary hip surgery. On the other hand, primary hip surgery does not reduce the risk of pelvic obliquity and scoliosis deformity progression.

Magnetically Controlled Growing Rods (MCGR) Versus Single Posterior Spinal Fusion (PSF) Versus Vertebral Body Tether (VBT) in Older Early Onset Scoliosis (EOS) Patients: How Do Early Outcomes Compare?

STUDY DESIGN

Retrospective review of prospective data from multicenter registry.

OBJECTIVE

Compare outcomes of posterior spinal fusion (PSF) versus magnetically controlled growing rods (MCGR) versus vertebral body tethers (VBT) in 8- to 11-year-old idiopathic early onset scoliosis (EOS) patients.

SUMMARY OF BACKGROUND DATA

In EOS, it is unclear at what age the benefit of growth-sparing strategies outweighs increased risks of surgical complications, compared with PSF.

METHODS

One hundred thirty idiopathic EOS patients, 81% female, aged 8-11 at index surgery (mean 10.5 yrs), underwent PSF, MCGR, or VBT. Scoliosis curve, kyphosis, thoracic and spinal height, complications, and Quality of Life (QoL) were assessed preoperatively and at most recent follow-up (prior to final fusion for VBT/MCGR).

RESULTS

Of 130 patients, 28.5% received VBT, 39.2% MCGR, and 32.3% PSF. The VBT cohort included more females (P < 0.0005), was older (P < 0.0005), more skeletally mature (P < 0.0005), and had smaller major curves (P < 0.0005). At follow-up, scoliosis curve corrected 41.1 ± 22.4% in VBT, 52.2 ± 19.9% in PSF, and 27.4 ± 23.9% in MCGR (P < 0.0005), however, not all VBT/MCGR patients finished treatment. Fifteen complications occurred in 10 VBTs, 6 requiring unplanned surgeries; 45 complications occurred in 31 MCGRs, 11 requiring unplanned surgeries, and 9 complications occurred in 6 PSFs, 3 requiring unplanned revisions. Cox proportional hazards regression adjusted for age, gender, and preoperative scoliosis curve revealed that MCGR (hazard ratio [HR] = 21.0, 95% C.I. 4.8-92.5; P < 0.001) and VBT (HR = 7.1, 95% C.I. 1.4-36.4; P = 0.019) patients were at increased hazard of requiring revision, but only MCGR patients (HR = 5.6, 95% C.I. 1.1-28.4; P = 0.038) were at an increased hazard for unplanned revisions compared with PSF. Thoracic and spinal height increased in all groups. QoL improved in VBT and PSF patients, but not in MCGR patients.

CONCLUSION

In older idiopathic EOS patients, MCGR, PSF, and VBT controlled curves effectively and increased spinal height. However, VBT and PSF have a lower hazard for an unplanned revision and improved QoL.Level of Evidence: 3.

The effectiveness and safety of acupuncture for scoliosis: A protocol for systematic review and/or meta-analysis

BACKGROUND

Scoliosis is a disease that affects all age groups and alters the three-dimensional deviation of the spinal axis. It is diagnosed when Cobb angle presents over 10 degrees and the reasons include aging, traumatic injuries, unknown origin, and disorders of congenital, neurological, musculoskeletal, and connective tissue. Scoliosis treatments are divided into surgical and conservative options. Surgery can correct the curved spine but has associated risks and economic burden. Conservative treatments, particularly bracing, prevent the progression of scoliosis, but still remains potential ingredient of curvation and patients poor compliance. Recent studies reported that various types of acupuncture can improve the curvation and the associated pain. However, there has been no systematic review on this issue. Therefore, this study will review the effectiveness and safety of acupuncture on scoliosis.

METHODS

Searching randomized controlled trials about the use of acupuncture for scoliosis will be performed using multiple electronic databases, manual search, and contact to authors e-mail if needed. We will select studies by the pre-defined criteria and summarize the data on study participants, interventions, control groups, outcome measurement, adverse events, and risk of bias. The primary outcome will be the Cobb angle, which is objective, and the secondary outcomes are associated with patient-centered indices (pain, functional status, and quality of life), which are subjective and adverse events. We will use Review Manager software (Version 5.3; Copenhagen; The Nordic Cochrane Center, The Cochrane Collaboration, 2014) to perform a meta-analysis and Cochrane Collaboration "risk of bias" tools to assess the risk of bias.

RESULTS

Our study will investigate the clinical evidence on the effectiveness and safety of acupuncture on scoliosis.

CONCLUSION

Our study will be informative to scoliosis patients, clinicians, policy makers, and researchers working with conservative management for scoliosis.
