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.
Background: Early definitive spinal fusion (EF) has been widely recommended to avoid spinal deformity progression for early-onset scoliosis (EOS) with neurofibromatosis type 1 (NF-1). In contrast, growing rod (GR) procedure has recently been recommended for EOS associated with the dystrophic type NF-1. However, no studies have compared the surgical outcomes between EF and GR procedure for EOS with NF-1. The purpose of this study was to compare the surgical outcomes of EF versus GR for early onset and dystrophic scoliosis with NF-1. Methods: This was a retrospective multicenter study; 26 EOS patients with dystrophic ty...
Background: Anterior vertebral body tethering (VBT) is a growth modulating and fusionless treatment option that is considered as a new promising method for the management of adolescent idiopathic scoliosis (AIS). This prospective cohort study aimed to present the minimum 2-year results of anterior VBT applied to 21 skeletally immature patients with AIS. Methods: Twenty-one skeletally immature patients with a diagnosis of AIS were included. A decision to proceed with surgery was established after the detection of curve progression despite the brace (>40 degrees) with a minimum curve flexibility of 30%. Results: P...
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
Tranexamic acid (TXA) is widely used in surgery for adolescent idiopathic scoliosis (AIS) and has been proved to be efficacious in reducing intraoperative blood loss (IBL) and the transfusion rate. However, the routine TXA regimen was intraoperative administration alone, in which the concentration of TXA could not cover the whole process of hyperfibrinolysis. And, its ability to control the massive postoperative blood loss (PBL) may be insufficient. Thus, we promoted a multiple-dose regimen of TXA for patients with AIS who underwent surgical correction.
Conclusions The studies here suggest that certain pediatric patient populations are at risk for impaired psychosocial functioning as a result of repetitive procedures. However, it is important to differentiate whether the association with poorer psychosocial outcomes is from the number of surgical procedures or whether the number if just a surrogate for increased disease complexity. Standardized psychosocial outcomes measures and future prospective, long-term, randomized clinical trials are also warranted.
CONCLUSIONS: Treatment safety in brace treatment for patients with scoliosis should be improved. One approach may be the use of standardized CAD libraries. Further investigations with study designs of higher evidence are necessary to support the results found in our investigation. PMID: 33025038 [PubMed - as supplied by publisher]
ConclusionThese clusters represent a new description of Lenke 1 AIS that comprises both coronal and sagittal measures of the spine combined with a measure of torso asymmetry. Automated identification of the clusters is accurate. The ability to identify subtypes of deformity, based on parameters that affect both the spine and the torso in AIS, leads to as better understanding of the totality of the deformity seen.
ConclusionThese early results show the feasibility and the proof of concept of spring-based distraction as a dynamic growth-enhancing system with the potential of further correction of the deformity after implantation.
