Abstract
BACKGROUND Severe rigid spinal deformities present significant challenges in correction surgery due to complexity and associated comorbidities. To mitigate the surgical risks, preoperative halo-pelvic traction (HPT) have been employed. This study aims to evaluate the effectiveness and safety of staged HPT combined with posterior spinal fusion (PSF) in the treatment of severe rigid spine deformity. METHODS This is a prospective cohort study. From 2020 to 2022, 61 consecutive patients (mean age 26.2 years) with severe rigid spine deformity who underwent staged HPT combined with PSF with a minimum 24-month follow-up were recruited. Radiographic parameters, clinical information, pulmonary functions tests, and perioperative complications were recorded. RESULTS The mean preoperative coronal Cobb angle was 114.2° ± 38°, and the mean MK was 105.8° ± 34.7°. Following the HPT ( mean duration 19.2 weeks), the mean coronal Cobb angle were corrected to 55.3° post-traction (50.6%) and 47.4° after PSF (58.3%); the mean MK angle were corrected to 52.6° post-traction (49.5%) and 38.1° after PSF (63.4%). The overall complication rate during HPT was 16.4%, while surgery-related complications were 18.0%, with no permanent neurological deficits observed. CONCLUSION Staged HPT combine with PSF is effective and safe for patients with severe rigid spine deformities. HPT could mitigate the severity of spine deformity, minimize the need for invasive three-column osteotomies, and reduce the risk of complications for correction surgery.

Abstract
BACKGROUND Halo-pelvic traction (HPT) is acknowledged for enhancing pulmonary function and reducing neurological complications in severe and rigid scoliosis and kyphoscoliosis. While its role in improving coronal balance is established, its impact on sagittal kyphosis remains under-researched. This study aims to assess HPT's effects on sagittal alignment in these conditions. METHODS A retrospective review of 37 patients with severe and rigid scoliosis or kyphoscoliosis was conducted to evaluate HPT's efficacy. The analysis focused on the impact of HPT on coronal and sagittal parameters, pulmonary function tests (PFTs) and complications. Radiographic assessments included main cobb angle in coronal, sagittal major kyphosis. RESULTS HPT was applied for an average of 2.9 months, significantly reducing the primary coronal curve from 127.7°±30.3° to 74.9°±28.3° (P < 0.05), achieving a 41.3% correction rate. Sagittal kyphosis correction was more pronounced, with angles decreasing from 80.4°±26.4° to 41.3°±24.4° (P < 0.05), resulting in a 48.6% correction rate. Pulmonary function tests showed improvements in forced vital capacity (FVC) (from 1.32 ± 0.91 to 1.55 ± 0.83) and forced expiratory volume in 1 s (FEV1) (from 1.03 ± 0.76 to 1.28 ± 0.72), with percentage predicted values also increasing (FVC%: 40.4%±24.3-51.4%±23.1%; FEV1%: 37.8%±25.2-48.1%±22.7%; all P < 0.05). CONCLUSION HPT effectively reduces spinal deformity severity and improves pulmonary function in patients with severe and rigid scoliosis and kyphoscoliosis. Sagittal kyphosis correction was notably greater than coronal scoliosis correction. The correlation between PFT improvements and coronal curve adjustments suggests that correcting the coronal Cobb angle is pivotal for pulmonary function enhancement.

Abstract
Halo gravity traction (HGT) is a preoperative modality for children with severe spinal deformity used to optimize spine flexibility and balance while decreasing the likelihood of neurologic injury. HGT is a dependable solution for these challenging spinal deformities. Aligning treatment guidelines and providing resources, education, and training for staff are key components for a successful HGT program. The HGT program at Children's Mercy Hospital was then developed with a systems approach with the holistic goal of multidisciplinary collaboration with physical/occupational therapy, hospital medicine, pulmonology, psychology, nutrition, child life, and complex care management. Education, research, and national collaboration to standardize this therapy should improve patient safety and support quality improvement.

Abstract
BACKGROUND Scoliosis is a high incidence disease that endangers the physical and mental health of adolescents. Traction therapy, as a conservative treatment plan, is helpful to improve the recovery speed of patients by studying the influence of different traction factors on the therapeutic effect. METHODS Based on the thin layer CT data of the lumbar spine of a 16-year-old patient with scoliosis, Mimics21.0 was used to extract the 3D digital model, and Geomagic Wrap2021 was used to perform the smooth surface. After that, SolidWorks was used to manually construct the structures, such as the intervertebral disc, and Ansys17.0 was used to add constraints, ligaments, and other features. Three-factor ANOVA was carried out after an orthogonal experiment that considered traction mode, traction angle, and traction force was finished. RESULTS ① A three-dimensional biomechanical model of lumbar scoliosis was created. ② The model's correctness was confirmed by comparing it to the corpse and other finite element models, as well as by verifying it under a range of working settings. ③ Traction force (P = 0.000), traction angle (P = 0.000), the interaction between traction force and traction angle (P = 0.000), and the interaction between traction mode and traction angle (P = 0.045) were all significant. ④ The interaction between traction force and traction angle has the most significant effect on Cobb, and traction with a certain angle is better than traditional axial traction. ⑤ Traction mode is not significant, but the interaction between traction mode and traction angle is significant. CONCLUSIONS A certain angle of traction can aid in improving outcomes and the traction force can be suitably decreased in the clinical formulation of the traction plan. The uniformity of correcting effect is more favorable when higher fixation techniques like positive suspension or traction bed traction are used, as opposed to overhanging traction.

Abstract
OBJECTIVE To determine, through a systematic review, the effects of halo gravity traction in spinal deformity. METHODS Prospective studies or case series of patients with scoliosis or kyphosis treated with cranial halo gravity traction (HGT) were included. Radiological outcomes were measured in the sagittal and/or coronal planes. Pulmonary function was also assessed. Perioperative complications were also collected. RESULTS Thirteen studies were included. Congenital etiology was the most frequent etiology observed. Most studies provided clinically relevant curve correction values in the sagittal and coronal planes. Pulmonary values improved significantly after the use of HGT. Finally, there were a pool of 83 complications in 356 patients (23.3%). The most frequent complications were screw infection (38 cases). CONCLUSIONS Preoperative HGT appears to be a safe and effective intervention for deformity that allows correction prior to surgery. However, there is a lack of homogeneity in the published studies.

Abstract
PURPOSE Preoperative preparation with halo gravity traction (HGT) has several advantages but is still controversial. A multicenter, observational, retrospective study was conducted to determine whether HGT provides better frontal correction in surgery for adolescent idiopathic scoliosis (AIS). METHODS Between 2010 and 2020, all patients who underwent posterior spinal fusion (PSF) AIS with a Cobb angle greater than 80° were included. The included patients who underwent HGT were compared (complications rate and radiographic parameters) to patients who did not undergo traction (noHGT). For patients who underwent HGT, a spinal front X-ray at the end of the traction procedure was performed. RESULTS Sixty-four in noHGT and forty-seven in HGT group were analyzed with a 31-month mean follow-up. The mean ratio of Cobb angle correction was 58.8% in noHGT and 63.6% in HGT group (p = 0.023). In HGT, this ratio reached 9% if the traction lasted longer than 30 days (p = 0.009). The complication rate was 11.7% with a rate of 6.2% in noHGT and 19.1% in HGT group (p = 0.07). In patient whose preoperative Cobb angle was greater than 90°, the mean ratio of Cobb angle correction increases to 6.7% (p = 0.035) and the complications rate increased to 14% in the no HGT group and decreased to 13% in the HGT group (p = 0.9). CONCLUSION HGT preparation in the management of correction of AIS with a Cobb angle greater than 90° is a technique providing a greater frontal correction gain with similar complication rate than PSF correction alone. We recommend a minimum halo duration of 4 weeks.

Abstract
Purpose Managing severe scoliosis is challenging and risky with a significant complication rate regardless of treatment strategy. In this retrospective comparative study, we report our results using a three-rod compared to two-rod construct in the surgical treatment of severe spine deformities to investigate which technique is safer, and which provides superior radiological outcomes. Methods Forty-six consecutive patients undergoing posterior spine fusion for scoliosis between 2006 and 2017 were identified in our institutional records. Inclusion criteria were minimum coronal deformity of 90°, age < 18 years at the time of surgery and a minimum 2 years of follow-up. Radiographic and clinical parameters, as well as post-operative complications were compared between the two groups. Results There were 21 patients in the three-rod group and 25 in the two-rod group. The mean preoperative major coronal deformity was 100°± 9 and 102°± 10 in the three-rod and two-rod, respectively (p = 0.6). The average major curve correction was 51% and 59% in three-rod and two-rod groups, respectively (p = 0.03). The post-operative thoracic kyphosis was 30°± 11 and 21°± 12 in the three-rod and the two-rod groups, respectively (p = 0.01). The surgical time was 476 ± 52 and 387 ± 84 min in three-rod and two-rod, respectively (p < 0.01). One patient in the two-rod cohort showed permanent post-operative sensory deficit. There were three unplanned returns to operating theater in the two-rod group. Conclusions Coronal correction was better with two-rod, whereas sagittal balance was superior with three-rod. Both techniques achieved balanced spine treating severe scoliosis. The two-rod technique was associated with a higher likelihood of requiring revision surgery. Level of evidence level 3.

[PMID: 36622456 DOI: 10.1007/s00586-023-07525-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2022] [Revised: 11/07/2022] [Accepted: 01/02/2023] [Indexed: 01/10/2023]
Abstract
PURPOSE To provide better evidence of the efficacy and safety of preoperative halo-pelvic traction on the improvements of deformity and pulmonary functions in patients with severe scoliosis. METHODS Electronic database searches were conducted including the Cochrane Library, PubMed, Web of Science and Embase. All studies of halo-pelvic traction for the management of severe spinal deformity were included. We referred to a list of four criteria developed by the Agency for Healthcare Research and Quality (AHRQ) to assess the quality of included studies. The meta-analysis was performed using RevMan 5.4 software. RESULTS Based on the study selection criteria, a total of eight articles consisting of a total of 210 patients were included. Statistically significant differences were found in coronal Cobb angle (P < 0.001), sagittal Cobb angle (P < 0.001) and height (P < 0.001) between pre- and post-traction. Sensitivity analysis was conducted, and there were substantial changes in heterogeneity with preoperative thoracoplasty subgroup in coronal Cobb angle (P < 0.001). Three trials including 74 subjects reported FVC and FEV1 predicted value between pre- and post-traction. There were statistically significant differences in FVC, FVC%, FEV1 and FEV1% (P < 0.001). The complication rate was 6.6-26.7%, and symptoms disappeared after reasonable traction strategy and intensive care. CONCLUSIONS Preoperative halo-pelvic traction achieved significant improvements in spinal deformity and pulmonary functions, with minor and curable complications. Thus, it is an effective and safe solution before surgery and may be the optimal choice for severe scoliosis. In light of the heterogeneity and limitations, future researches are needed to better determine the long-term efficacy on comprehensive assessment and to explore the appropriate traction system.

Abstract
PURPOSE To report the results of prolonged post-operative halo-gravity traction in a patient in whom the surgery had to be interrupted unexpectedly and for whom subsequently specific clinical circumstances contraindicated completion of the surgical procedure. METHODS The patient was a 15-year-old male with severe cervico-dorsolumbar lordoscoliosis who was being studied for associated diffuse axonal injury. He performed halo-gravity traction for 12 weeks. Subsequent surgical management consisted of occipito-lumbar posterior instrumented fusion. During the surgical approach, electrocardiographic changes with hemodynamic decompensation were detected that did not improve with anesthetic reanimation. The intervention was stopped, the surgical wound was closed, and the patient was transferred to the intensive care unit (ICU). It was decided that a revision surgery with the aim to continue with the previous strategy would imply a high risk of perioperative morbidity and mortality. RESULTS Orthopedic management was decided upon consisting of continued halo-gravity traction with wheelchair modification at home, which was extended to a period of 12 months because of the good results obtained in terms of cervicothoracic realignment. Two years after halo-gravity discontinuation, clinical and radiographic occipito-cervical alignment was good and the patient conserved certain occipito-cervical range of motion and had the capacity of maintaining a horizontal gaze. CONCLUSION We considered the outcome extraordinary and relevant in this complex and unusual patient. A longer follow-up will provide more data regarding the final outcome of this treatment.

BMC Musculoskelet Disord 2022; 23:775. [PMID: 35964038 PMCID: PMC9375359 DOI: 10.1186/s12891-022-05732-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2022] [Accepted: 08/01/2022] [Indexed: 11/18/2022] Open
Abstract
Background The treatment of severe and rigid scoliosis is challenging. We developed a surgical strategy for severe and rigid scoliosis since 2014. This study aimed to retrospectively analyze the safety and efficacy of apical region correction and global balance with 3 rods as a surgical strategy for the treatment of severe and rigid scoliosis. Methods A retrospective study was performed for patients with severe and rigid scoliosis who underwent one-stage posterior corrective operation using the apical region correction and global balance with 3 rods surgical strategy between February 2014 and April 2020. The inclusion criteria were as follows: [1] Cobb angle > 90°; [2] flexibility < 30%; [3] a minimum 2-year follow-up. Patients were excluded if they had a history of traction or spinal surgery. Coronal and sagittal parameters, including Cobb angle, flexibility, apex vertebra translation, trunk shift (TS), thoracic kyphosis, lumbar lordosis, and sagittal vertical axis (SVA) were measured preoperatively, postoperatively and at the final follow-up. The Scoliosis Research Society 22-item questionnaire was administered preoperatively and at the final follow-up. During the operation, one slightly-bent short rod was placed into the concave side of apical region and correction was achieved by rod-rotation and distraction. Two pre-bent long rods were placed into both sides of the scoliosis and global balance was improved by leveling the proximal thoracic vertebrae and distal lumbar vertebrae. Results A total of 41 patients were included, with an average age of 20 years (range, 12–49 years) and follow-up of 34 months (range, 24–58 months). Postoperative correction rate was 53% for scoliosis. There were 14 patients with normal kyphosis before surgery, and 28 patients with normal kyphosis at the last follow-up. 88% of the patients (23/26) with preoperative coronal imbalance (TS > 20 mm) restored coronal balance at the final follow-up. 87% of the patients (14/16) with preoperative sagittal imbalance (SVA > 40 mm) restored sagittal balance at the final follow-up. The mean operation time and blood loss were 286 min and 941 mL, respectively. No patients had neurological complications or implant failure. Conclusion The surgical strategy of apical region correction and global balance with 3 rods is a safe and effective alternative for the surgical treatment of severe and rigid scoliosis.

Abstract
OBJECTIVE Halo gravity traction (HGT) is an effective way of managing pediatric spinal deformities in the preoperative period. This study comprehensively reviews the existing literature and evaluates the effect of HGT on various radiographic parameters regarding spinal correction and, secondarily, evaluates the improvement in pulmonary function as well as nutritional status. METHODS In accordance with PRISMA guidelines, a comprehensive search was conducted for articles on HGT in the treatment of spinal deformity. Spinal deformity after traction and surgery, change of pulmonary function, nutritional status, and prevalence of complications were the main outcome measurements. All meta-analyses were conducted using random models according to the between-study heterogeneity, estimated with I2. RESULTS A total of 694 patients from 24 studies were included in this review. Compared with pretraction values, the average coronal Cobb angle reduction after traction was 27.66° (95% confidence interval [CI], 23.41-31.90; P < 0.001) and 47.43° (95% CI, 39.32-55.54; P < 0.001) after surgery. The sagittal Cobb angle reduction after HGT and surgery was 27.23° (95% CI, 22.83-31.62; P <0.001) and 36.77° (95% CI, 16.90-56.65; P < 0.001), respectively. There was a statistically significant improvement in the overall pulmonary function, as evident by an increase in a forced vital capacity of 8.44% (95% CI, -5.68 to -11.20; P < 0.001), and an increase in nutritional status, with a percentage correction of body mass index by 1.58 kg/m2 (95% CI, -2.14 to -1.02; P < 0.001) after HGT application. CONCLUSIONS HGT has been shown to significantly improve coronal deformities, sagittal deformities, nutritional status, and pulmonary function in the preoperative period.

Abstract
PURPOSE To compare the perioperative outcome and operative cost of posterior spinal fusion (PSF) surgery between severe and non-severe Lenke 1 and 2 adolescent idiopathic scoliosis (AIS) patients. METHODS A total of 509 AIS patients who underwent single-staged PSF between 2013 and 2020 were reviewed. Fifty-four severe scoliosis patients (Cobb angle ≥ 90°) were categorized into Gp1, and 455 non-severe scoliosis (Cobb angle < 90°) patients into Gp2. Propensity score matching (PSM) analysis using one-to-one nearest neighbor matching and match tolerance of 0.001 were performed. Outcome measures were operative time, intraoperative blood loss (IBL), allogeneic transfusion rate, perioperative complication, length of stay, fusion level, number of screws used, postoperative Cobb angle, correction rate (CR), side bending correction index (SBCI) and operative cost. RESULTS From the PSM analysis, 35 patients from each group were matched. The operative time was 155.9 ± 41.4 and 130.0 ± 30.3 min for Gp1 and Gp2, respectively (p = 0.004). The IBL was 1349.2 ± 1019.0 and 781.9 ± 325.1 mLs for Gp1 and Gp2, respectively (p = 0.003). Fusion level (12.5 ± 0.8 vs. 11.2 ± 1.3, p < 0.001) and number of screws used (16.4 ± 1.6 vs. 14.6 ± 1.4, p < 0.001) were higher in Gp1. Four perioperative complications were observed in Gp1 compared to none in Gp2 (p < 0.039). Gp1 had larger postoperative Cobb angle (p < 0.001), lower CR (p = 0.005) and higher SBCI (p < 0.001). The operative cost was higher in Gp1 (p < 0.001). CONCLUSIONS Severe Lenke 1 and 2 AIS patients had poorer perioperative outcome, higher complication rate, longer fusion and higher operative cost than non-severe AIS.

Abstract
ABSTRACT Objective: To determine which method is more effective – cranial halo traction or temporary internal distraction – in staged surgeries for patients with severe (≥ 100°) and stiff (<25% flexibility) scoliosis. Methods: A sample of 12 patients with traction and 7 patients without traction, operated on between January 2013 and December 2017. The patients’ demographic data, the type of surgery performed, complications, and coronal and sagittal alignment parameters were recorded before surgery and in the final follow-up. The data were processed in SPSS 20.0. Comparisons were made between the means (Student's t-test) and the clinical and procedure-related characteristics (likelihood ratio and Fisher's Exact tests), at a confidence level of 0.05. Results: There were no significant intergroup differences for clinical characteristics, complications or degree of correction. However, more patients in the group submitted to temporary internal distraction required vertebral resection osteotomies during definitive surgery (p<0.05). Conclusions: Based on the results, it was not possible to establish which is the most effective method, but it is suggested that staged traction may be more effective, and safer, particularly when the surgeon is less experienced, during surgery on patients with severe and stiff scoliosis.

Abstract
Objective To evaluate the feasibility, clinical efficacy and imaging results of preoperative traction (PT) followed by percutaneous kyphoplasty (PKP) combined with percutaneous cement discoplasty (PCD) for treating severe thoracolumbar osteoporotic vertebral compression fractures (OVCFs). Methods A total of 13 patients with severe thoracolumbar OVCFs treated by PT followed by PKP combined with PCD were enrolled. General information, PT time, operation time, postoperative hospital stay, perioperative complications, visual analog scale (VAS) score, Oswestry disability index (ODI) score, local kyphosis angle, intervertebral angle (IVA), anterior vertebral height (AVH) and posterior vertebral height (PVH) were recorded. Results The average VAS score at admission was 7.4±3.5, decreased to 4.3±1.7 after PT and 2.3±0.7 three days after operation, and 1.5±0.9 at last follow-up. The average ODI score was 73.7±21.4 before operation, decreased to 26.6±9.3 three days after operation and 13.7±7.1 at last follow-up. Compared to VAS and ODI scores at admission, these at the third day after operation and last follow-up were significantly different. At admission, the IVA was 3.4°±6.8°, the disc height was 5.7±1.2mm, the AVH was 10.7±3.2mm, and the PVH was 25.7±4.2 mm, which, after PT, changed to 8.1°±7.3°, 8.6±2.6mm, 18.5±2.8mm, and 26.2±7.1mm, respectively, and the differences were significant. The average kyphotic angle was 43.4°±17.8° at admission, and decreased to 26.3°±6.7° after PT, 17.5°±8.4° three days after operation and 19.1°±10.3° at last follow-up, and the differences were significant. Conclusion PT followed by PKP combined with PCD for the treatment of severe thoracolumbar OVCFs was an effective and simple procedure with satisfactory short-term clinical outcomes by relieving pain and improving kyphosis.

Abstract
PURPOSE Definitive fusion can be considered in early onset scoliosis (EOS) around triradiate cartilage closure. Halo-gravity traction (HGT) is an old strategy that can help lengthen and balance the spine before fusion. The postoperative changes of the trunk have never been investigated to date with modern imaging. The goal of this study was to analyze the 3D radiological outcomes, and the associated pulmonary function, of a cohort of severe EOS patients treated by definitive posterior fusion prepared by HGT. METHODS All consecutive EOS patients with severe (> 85°) and stiff (flexibility < 25%) curves, treated by HGT followed by posterior fusion, were followed. 3D radiological measurements and pulmonary function were assessed. RESULTS Forty-nine EOS patients underwent fusion, with a mean follow-up of 4 years (± 1). Age at surgery averaged 13.5 years old. HGT protocol reached on average 41% of body weight. Mean preoperative 3D Cobb angle was 95° (± 10) and final correction averaged 68.4% after surgery. 3D T4T12 kyphosis was reduced after surgery (11°, p < 0.01), while the apical vertebral rotation was improved by 27.8% (p = 0.06). 3D thoracic volume increased after surgery (p = 0.02), with a 3D T1T12 height gain averaging 3.7 cm (± 2). Both parameters were significantly correlated with total lung capacity improvement. Seven complications (14.2%) were reported, and 5 patients (10.6%) underwent unplanned revision. CONCLUSION HGT is a safe and efficient strategy to prepare posterior fusion in severe EOS patients. The 3D trunk analysis demonstrated significant postoperative gains in thoracic and spinal lengths, as well as in thoracic volume. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE The correction of severe, stiff scoliosis in children is challenging. One method used to reduce the risk is preoperative halo gravity traction (HGT). In this study, the authors sought to define the efficiency and safety of HGT and characterize the chronology of the correction seen. METHOD A consecutive group of pediatric patients with severe spinal deformities was treated with HGT before definitive correction. A standard protocol with the daily addition of weight to 50% of body weight at 3 weeks was used. Traction remained in place until signs of impending neurological complication or 6 weeks, whichever was sooner. RESULTS Twenty-four patients were included with a mean age of 11.8 years. The mean coronal deformity was 123 degrees, with a T1-L5 height of 234 mm. The mean duration of traction was 42 days with a mean improvement in height of 72 mm with 82% occurring over the first 3 weeks. Hundred percent of the angular and 98% of T1-L5 height correction was reached by 6 weeks.One patient showed early signs of a cranial nerve palsy prompting early surgery and 8 patients showed pin loosening, 1 of which required revision of their halo. One patient underwent a slower progression of traction because of transitory urinary disturbance. Following fusion, angular correction of the major curve was 49%. CONCLUSION HGT is a safe treatment for severe, stiff scoliosis because it can respond to early signs of impending neurological impairment. The first 3 weeks of treatment, reaching 50% of body weight as a traction force accounts for 80% of correction, with the remaining 20% in the following 2 weeks. At least 4 weeks of traction is recommended when following this protocol.

Abstract
PURPOSE The three-rod technique, utilising a short apical concavity rod is an option to achieve controlled correction in severe scoliosis. We describe this technique, the complications encountered, and the long-term outcomes. METHOD All paediatric patients who had at least 2 years follow-up after undergoing corrective surgery for scoliosis ≥ 100° using 3 parallel rods were included. Radiographs were assessed to evaluate the correction and clinical records examined for any loss of correction, complications, revision procedures or neuromonitoring events. RESULTS Twenty-five patients met the inclusion criteria. Four underwent prior anterior fusion to prevent crankshaft phenomenon. The mean angle of the deformity was 112.0° (range 100.3-137.1). Mean maximal kyphosis was 48.8° (range 11.4-78.8°) and mean curve flexibility 4.4% (range 0-37.0%). Intraoperative traction achieved an average of 70.4% (95% CI 56.6-84.1%). Nine patients (39%) showed a reduction in MEPs during definitive surgery. All returned to within 75% of baseline by the end of surgery. All patients had normal postoperative neurology. One patient underwent removal of hardware for late infection. The mean overall Cobb correction was 55.7° (95% CI 50.2-61.2°), equating to 50.2% (95% CI 44.9-55.4%) of the mean initial deformity. Thoracic kyphosis reduced by a mean of 18.2° (95% CI 12.8-23.6°). CONCLUSION Our series suggests that three-rod constructs are able to safely and effectively achieve 50% correction of severe scoliosis.

How helpful is the halo-gravity traction in severe spinal deformity patients?: A systematic review and meta-analysis. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:3162-3171. [PMID: 34185131 DOI: 10.1007/s00586-021-06902-4] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Accepted: 06/14/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE This study sought to evaluate the complications and clinic outcome in radiographic parameters, pulmonary function, and nutritional status of halo-gravity traction (HGT) in treating severe spinal deformity. METHODS Embase, PubMed, Cochrane, Web of Science databases were searched comprehensively for relevant studies from inception to February 2021, by using combined text and MeSH terms and English language restriction was used. The data, including radiographic parameters, pulmonary function (FVC %), and nutritional status (BMI) was extracted from included studies. All meta-analyses were conducted using random or fixed-effects models according the between-study heterogeneity, estimated with I2. RESULTS Four hundred and forty-six studies were identified and twelve studies with a total of 372 patients were included in this review. Compared with pre-traction values, there were reduction in cobb angle of 28.12° [95% CI (22.18, 34.18)], decrease in thoracic kyphosis of 26.76°[95% CI (20.73, 32.78)], improvements in spine height[SMD = -0.89, 95% CI (- 1.56, - 0.21)] and in coronal balance[WMD = - 0.03, 95% CI (- 1.56, - 0.21), P = 0.84] with preoperative halo-gravity traction for severe spinal deformity patients. Besides, our pooled analysis showed the improvement in pulmonary function (FVC %) [WMD = - 9.56, 95% CI (- 1.56, - 0.21)] and increase in nutritional status (BMI) [WMD = - 0.50, 95% CI (- 1.56, - 0.21)]. CONCLUSION Partial correction can be achieved by preoperative HGT, thereby reducing the difficulty of the operation and the risk of neurologic injury caused by excessive correction. Moreover, preoperative HGT can improve pulmonary function and nutritional status and, thus, increase patients' tolerance to surgery.

Distraction forces on the spine in early-onset scoliosis: A systematic review and meta-analysis of clinical and biomechanical literature. J Biomech 2021; 124:110571. [PMID: 34174488 DOI: 10.1016/j.jbiomech.2021.110571] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 06/02/2021] [Accepted: 06/07/2021] [Indexed: 11/21/2022]
Abstract
Distraction-based growing rods are frequently used to treat Early-Onset Scoliosis. These use intermittent spinal distractions to maintain correction and allow for growth. It is unknown how much spinal distraction can be applied safely. We performed a systematic review and meta-analysis of clinical and biomechanical literature to identify such safety limits for the pediatric spine. This systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Three systematic searches were performed including in-vivo, ex-vivo and in-silico literature. Study quality was assessed in all studies and data including patient- or specimen characteristics, distraction magnitude and spinal failure location and ultimate force at failure were collected. Twelve studies were included, 6 in-vivo, 4 ex-vivo and 2 in-silico studies. Mean in-vivo distraction forces ranged between 242 and 621 N with maxima of 422-981 N, without structural failures when using pedicle screw constructs. In the ex-vivo studies (only cervical spines), segment C0-C2 was strongest, with decreasing strength in more distal segments. Meta-regression analysis demonstrated that ultimate force at birth is 300-350 N, which increases approximately 100 N each year until adulthood. Ex-vivo and in-silico studies showed that yielding occurs at 70-90% of ultimate force, failure starts at the junction between endplate and intervertebral disc, after which the posterior- and anterior long ligament rupture. While data on safety of distraction forces is limited, this systematic review and meta-analysis may aid in the development of guidelines on spinal distraction and may benefit the development and optimization of contemporary and future distraction-based technologies.

Abstract
Background: Halo-traction device has been seen with favorable outcome in managing the patients with severe kyphotic deformities preoperatively, however, associated complications are inevitable. Slight modifications can improve the outcome and clinical efficacy. Case Description: A 14-year-old boy was presented with severe kyphotic deformity of 141° from T1 to T10 thoracic vertebrae with diffuse paraspinal calcification in thoracic spine and complete loss of power of both lower limbs. A modified halo-pelvic distraction device was applied before the definitive surgery. The device comprised halo and pelvic assembly, the halo ring was connected to the head with 06 pins, while pelvic assembly had Ilizarov half pins connected to the arches. The assembly construct had four threaded rods, two of them were placed anterolateral and the other two were posterolateral. Distraction at the rate of 3 mm/day was started from 1st postoperative day for 35 days. The neurology improved in both lower limbs and kyphotic angle reduced to 56° from 141°. Surgery at this stage was done and a standalone solid titanium cage was placed from T1 to T10 vertebral body after debridement. No peri- or post-operative complications were observed. Conclusion: The application of halo-pelvic distraction before corrective surgeries can not only reduce the severity of the kyphotic deformity making the definitive surgery easy but neurology can also be improved. The high-risk complications associated with acute correction of deformities can be minimized using our modified halo-pelvic distraction device.

Abstract
Background In spine surgery, the halo fixator was initially utilized to stabilize cervical fusions in patients with poliomyelitis. More recently, the indications for halo fixation have evolved to include stabilization and definitive treatment for upper cervical spine injuries (Jefferson fractures, atlanto-occipital dissociations, odontoid fractures, etc.), treatment of atlantoaxial rotatory subluxation, stabilization of long cervical fusions, and preoperative traction. In the realm of pediatric spinal deformity, halo fixation has proved to be a valuable resource for severe or neglected spinal deformities. In this video article, we demonstrate the application of a halo fixator in a pediatric patient with severe scoliosis. Description The procedure includes appropriate pin placement in the safe zones of the skull performed under either general anesthesia or local anesthesia. Pins are secured to a halo frame that is sized to be 2 cm larger than the circumference of the skull and are tightened according to age-specific torque guidelines. Alternatives Alternative treatments vary from cervical spine immobilization to definitive surgical treatment in the spine, or even spinal osteotomies, depending on the underlying spinal pathology. Rationale The halo fixator works by limiting motion of the cervical spine in flexion, extension, and axial rotation. The halo is also able to control and correct translational injuries of the cervical spine. In the setting of spinal deformity, the halo fixator can also be utilized to overcome the effects of gravity and lengthen the spine. Expected Outcomes For spinal deformities, the halo fixator can be expected to lengthen the spine and increase deformity flexibility prior to definitive surgical treatment in the spine or growth-friendly spinal instrumentation. Important Tips Correct identification of safe zones for pin placement is vital to correct pin placement.For pediatric patients, it is important to obtain fixation with a minimum of 6 to 8 pins.Pins should be tightened with use of a torque-limiting wrench, up to no more than 1 in/lb (55.9 mm/kg) per year of age, up to a maximum of 8 in/lb (447.9 mm/kg).Applied traction should be a maximum of 50% of the body weight of the patient.Neurovascular examination is vital following application of weight.

Abstract
Background The severe rigid deformity patients with pulmonary dysfunction could not tolerate complicated corrective surgery. Preoperative traction are used to reduce the curve magnitude and improve the pulmonary function before surgery, including halo-gravity traction (HGT) and halo-pelvic traction (HPT). The present study aimed to retrospectively compare the radiographic, pulmonary and clinical outcomes of preoperative HGT and HPT in severe rigid spinal deformity with respiratory dysfunction. Methods 81 cases of severe rigid kyphoscoliosis treated with preoperative traction prior to corrective surgery for spinal deformity between 2016 and 2019 were retrospectively reviewed. Two patient groups were compared, HPT group (N = 30) and HGT group (N = 51). Patient demographics, coronal and sagittal Cobb angles and correction rates, pulmonary function, traction time, osteotomy grade, and postoperative neurological complications were recorded for all cases. Results The coronal Cobb angle was corrected from 140.67 ± 2.63 to a mean of 120.17 ± 2.93° in the HGT group, and from 132.32 ± 4.96 to 87.59 ± 3.01° in the HPT group (mean corrections 15.33 ± 1.53 vs. 34.86 ± 3.11 %) (P = 0.001). The mean major sagittal curve decreased from 134.28 ± 3.77 to 113.03 ± 4.57° in the HGT group and from 129.60 ± 8.45 to 65.61 ± 7.86° in the HPT group (P < 0.001); the mean percentage corrections were 16.50 ± 2.13 and 44.09 ± 9.78 % (P < 0.001). A significant difference in the pulmonary function test results was apparent between the two groups; the mean improvements in the FVC% of the HGT and HPT groups were 6.76 ± 1.85 and 15.6 ± 3.47 % (P = 0.024). The HPT group tended to exhibit more FEV% improvement than the HGT group, but the difference was not significant (5.15 ± 2.27 vs. 11.76 ± 2.22 %, P = 0.91). Conclusions Patients with severe rigid kyphoscoliosis who underwent preoperative HPT exhibited better radiographic correction of the deformity, and pulmonary function, and required fewer osteotomies compared to the HGT group. Thus, HPT may be useful for severe rigid spinal deformity patients with pulmonary dysfunction.

EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2021; 30:788-796. [PMID: 33409729 DOI: 10.1007/s00586-020-06709-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/29/2020] [Revised: 10/02/2020] [Accepted: 12/23/2020] [Indexed: 12/01/2022]
Abstract
INTRODUCTION Correction of severe idiopathic scoliosis poses surgical challenges. Treatment options entail anterior and/or posterior release, Halo-gravity traction (HGT) and three-column osteotomies (3CO). The authors report results with a novel technique of temporary short-term magnetically controlled growing rod (MCGR) as part of a posterior-only strategy to treat severe idiopathic major thoracic curves (MTC). METHODS Seven patients with MTC > 100° treated with temporary MCGR were included. Mean age was 15 years. Preoperative MTC was av. 118° and TC-flexibility av. 19.8%. Patients underwent posterior instrumentation, periapical release using advanced Ponte osteotomies, segmental insertion of pedicle screws and a single MCGR. After av. 14 days, the second surgery was performed with removal of MCGR and final correction and fusion. The spinal height from lowest instrumented vertebra (LIV) to T1 was measured. MTC-correction and scoliosis correction index (SCI) were calculated. RESULTS No patient suffered a major complication or neurologic deficit. Instrumentation was from T2 to L3 or L4. This kind of staged surgery achieved a correction of postop MTC to av. 39°, MTC-correction 67% and SCI of av. 4.3. Spinal height T1-LIV increased from preoperative av. 288 mm to postoperative av. 395 mm indicating an increase of > 10 cm. CONCLUSION This is the first series of AIS patients that had temporary MCGR to treat severe thoracic scoliosis. A staged protocol including internal temporary distraction with MCGR after posterior release and definitive correction resulted in large MTC-correction and restoration of trunk height. Results indicate that technique has the potential to reduce the necessity for HGT and high-risk 3CO for the correction of severe scoliosis.

Abstract
Introduction Strong halo-femoral traction has been widely used in the field of severe rigid scoliosis correction. The objective of this study was to analyze the corrective contribution of strong halo-femoral traction in the treatment of severe rigid nonidiopathic scoliosis and discuss its meaning. Material and methods A retrospective review was performed for patients with severe rigid nonidiopathic scoliosis who were treated with halo-femoral traction in our center from December 2008 to December 2015. All cases underwent halo-femoral traction for 2 to 4 weeks before a one-stage posterior operation, and the absolute and relative contribution rates of each orthopedic factor (bending, fulcrum, traction, surgery) were analyzed. Results A total of 38 patients were included (15 males and 23 females), with a mean age of 16.4 ± 3.73 years (10–22 years) and follow-up of 55.05 ± 6.63 months (range 40–68 months). The etiology was congenital in 17 patients, neuromuscular in 14 patients, neurofibromatosis-1 in 3 patients, and Marfan syndrome in 2 patients. Congenital high scapular disease with scoliosis was found in 2 patients. The mean coronal Cobb angle of the major curve was 97.99° ± 11.47° (range 78°–124°), with a mean flexibility of 15.68% ± 6.65%. The absolute contribution rate (ACR) of bending was 27.26% ± 10.16%, the ACR of the fulcrum was 10.91% ± 2.50%, the ACR of traction was 32.32% ± 11.41%, and the ACR of surgery was 29.50% ± 9.70%. A significant difference in correction was noted between the ACRs of traction and the fulcrum (P < 0.05). Discussion Strong halo-femoral traction plays a relatively significant role in the treatment of severe rigid nonidiopathic scoliosis while decreasing the risk of operation, and it is a safe and effective method for the treatment of severe rigid nonidiopathic scoliosis.

Abstract
OBJECTIVE To evaluate the clinical efficacy of short-term halo-pelvic traction (HPT) combined with surgery in the treatment of severe spinal deformities. METHODS In the study, 24 patients diagnosed as severe spinal deformity accepted the treatment of one-stage short-term HPT and two-stage surgery from January 2015 to May 2018 in our orthopedics department. 24 cases (9 males and 15 females) were retrospectively reviewed. The average age of the cohort was (28.8±10.0) years (12-48 years). The height, scoliosis angle, kyphosis angle, the height difference of shoulders, the height difference of crista iliaca, C7PL-CSVL and the perpendicular distance of S1 and the convex point of the patients were assessed at pre-traction, post-traction and post-surgery. The paired t test was used to analyze the difference among pre-traction, post-traction and post-surgery. RESULTS The average traction time of 24 cases was (2.5±1.1) weeks (1-5 weeks). The height of pre-traction and post-traction were (141.7±11.2) cm (116-167 cm) and (154.1±9.5) cm (136-176 cm) respectively, showing significant difference (P < 0.05), and the increased height was (12.4±4.6) cm (4-20 cm). The average scoliosis angle before traction was 104.9°±35.0°(25°-158°), and it was significantly decreased in post-traction[64.8°±21.0°(19°-92°)] and post-surgery[39.3°±17.0° (10°-70°)] (P < 0.05). The traction's coronal correction rate was 37.2%±10.9% (11.9%-51.2%) and the total coronal correction rate was 61.9%±12.6%(26.9%-79.0%). The average kyphosis angle before traction was 106.9°±29.2°(54°-163°), and it was significantly decreased in post-traction [63.1°±17.1°(32°-92°)] and post-surgery [39.0°±16.8°(10°-68°)](P < 0.05). The traction's sagittal correction rate was 40.0%±10.7%(16.7%-55.5%) and the total sagittal correction rate was 64.3%±10.7%(49.0%-87.5%). The average C7PL-CSVL before traction was (3.2±2.8) cm, and it was significantly decreased in post-traction [(2.5±2.5) cm] (P < 0.05). The perpendicular distance of S1 and the convex point before traction was (10.5±4.8) cm, and it was significantly decreased in post-traction[(8.4±3.5) cm] (P < 0.05). CONCLUSION The one-stage short-term HPT combined with two-stage surgery is a safe and effective procedure for severe spinal deformities. The clinical efficacy is satisfactory and the complication is relatively less.

Abstract
Background Halo traction has been used as an adjunctive method in the treatment of severe spinal deformities. But there are few reports on the clinical efficacy of halo-pelvic traction (HPT) in the treatment of severe spinal deformities complicated with respiratory dysfunction. This study was to evaluate the clinical efficacy and complications associated with pre-operative HPT in the treatment of severe spinal deformities with respiratory dysfunction. Methods Thirty patients with severe spinal deformities complicated with respiratory dysfunction treated with short-term pre-operative HPT were retrospectively reviewed. Inclusion criteria were: (1) patients with severe kyphoscoliosis (coronal Cobb angle or kyphosis angle ≥100°) and respiratory failure, (2) patients undergoing HPT until posterior fusion surgery. All patients underwent general anesthesia for HPT application, which the pelvic ring used in this study was a half-ring, and the rods were all placed on the anterolateral side of the truck. Results The major coronal curve scoliosis averaged 116.00 ± 16.70° and was reduced to 63.23 ± 14.00° after HPT, 46.33 ± 10.70° after surgery. The major kyphosis was 102.40 ± 27.67° and was reduced to 52.23 ± 14.16° after HPT, 42.0 ± 11.92° after surgery. A significantly increased FVC was observed after HPT (p < 0.001), with a significantly improved FVC% (p < 0.001). Similarly, a significantly increased FEV1 was also observed (p < 0.001), with a significantly improved FEV1% (p < 0.001). Conclusion This study indicated that the modified HPT could be used to help patients with severe spinal deformities complicated with respiratory dysfunction achieve significant correction in both the coronal and sagittal deformities during the pre-operative treatment period along with improved respiratory function and in the absence of severe complications.

Development of a spring-based weight system for halo gravity traction for complex pediatric spinal deformity. Spine Deform 2020; 8:879-884. [PMID: 32303999 DOI: 10.1007/s43390-020-00117-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 04/06/2020] [Indexed: 10/24/2022]
Abstract
STUDY DESIGN Description of technique. OBJECTIVES Describes the redesign of free-weight-based halo gravity traction wheelchairs and walkers to a spring-based system. The treatment of severe pediatric spinal deformities is challenging and associated with significant morbidity. Halo gravity traction (HGT) can be utilized to assist in the correction of severe spinal deformities. A time period of traction may also be used to medically optimize patients prior to surgery. Implementing HGT therapy requires specialized equipment, specially trained hospital staff, as well as significant commitment from caregivers. This study describes the transition from a free weight-based HGT equipment to a spring-based weight system. The new system is expected to decrease the burden of care and improve safety for patients and their families. METHODS A thorough interview process was carried out to gather data on existing HGT systems. All stakeholders, including orthopedic technicians, nurses, surgeons, patients and their families were asked questions on how to improve the equipment and process. With colleagues at a partner children's hospital, new HGT wheelchairs and walkers with a spring-based weight system were designed and built. RESULTS Spring-based weight HGT wheelchairs and walkers are more economical to build, safer, and easier to operate than free-weight-based systems. A cost analysis found that spring-based systems cost $780 less compared to free weight-based systems. In addition, the new spring-based wheelchairs and walkers are about 50% lighter with improved weight distribution making them safer to operate and easier to transport. There is consensus among surgeons, nurses, and families that the redesigned units are easier to operate. CONCLUSIONS Spring-based weight HGT systems are economically viable and clinically effective for pre-operative traction for children with severe spinal deformities. They are well tolerated by patients and easy to care for by nursing and surgical staff. LEVELS OF EVIDENCE III.

Abstract
STUDY DESIGN A retrospective, comparative study. OBJECTIVE To compare the results, complications, and costs of preoperative halo-gravity traction in in- and outpatient settings. BACKGROUND DATA Surgical management of severe spinal deformities remains complex and controversial. Preoperative halo-gravity traction results in a decreased need for aggressive surgical techniques, lower incidence of intraoperative neurologic complications, and improvement of nutritional parameters and preoperative cardiopulmonary function. METHODS Twenty-nine patients younger than 18 years with kyphoscoliosis undergoing preoperative halo-gravity traction were divided into two groups: inpatients (n: 15) and outpatients (n: 14, home care or care at the Foundation). Traction time (weeks), traction weight (kg), radiographic curve correction, complications, and costs were compared. For statistical analysis, t test and odds ratio were calculated with a significance of p < 0.05. RESULTS Mean traction time was 6 weeks for in- and 4 weeks for outpatients (p = 0.038). Initial traction weight was 6 kg in both groups, while final traction weight was 13 kg for in- and 15 kg for outpatients (p = 0.50). At the end of the traction period, coronal correction was 24° in in- and 28° in outpatients (p = 0.5), while sagittal correction was 27° and 29°, respectively (p = 0.80). Pin loosening was observed in 2 patients in each group, of whom 1 outpatient developed pin-site infection. In each group, one patient developed transient neurologic complications (odds ratio 1.091). Mean treatment cost per patient was 2.8-fold higher in inpatients. CONCLUSIONS Considering complications and costs, our results show that preoperative halo-gravity traction in an outpatient setting is an option to be taken into account. LEVEL OF EVIDENCE Grade III.

Abstract
Objective To compare the changes of scoliosis and kyphosis angles after Halo-pelvic traction with posterior spinal osteotomy versus simple posterior spinal osteotomy for severe rigid spinal deformity. Methods A clinical data of 28 patients with severe rigid spinal deformity between January 2015 and November 2017 was retrospectively analyzed. Sixteen patients were treated by Halo-pelvic traction with posterior spinal osteotomy (group A) and 12 patients were treated with posterior spinal osteotomy only (group B). There was no significant difference between the two groups ( P>0.05) in gender, age, body mass index, and preoperative pulmonary function, coronal and sagittal Cobb angles, and flexibility. The operation time, intraoperative blood loss, and complications were recorded. The coronal and sagittal Cobb angles were measured on X-ray films before operation (before traction in group A), at 10 days after operation, at last follow-up in the two groups and after traction in group A. The improvement rate of deformity after traction in group A, the correction rate of deformity after operation, and the loss rate of correction at last follow-up were calculated. Results All patients were followed up 24-30 months (mean, 26.5 months). The operation time and intraoperative blood loss were significantly less in group A than in group B ( t=7.629, P=0.000; t=8.773, P=0.000). In group A, 1 patient occurred transient numbness of both legs during continuous traction and 2 patients needed ventilator support for more than 12 hours. In group B, 7 patients needed ventilator support for more than 12 hours, including 1 patient with deep incision infection. The incidence of complications was 18.75% (3/16) in group A and 58.33% (7/12) in group B, and the difference between the two groups was significant ( χ 2=4.680, P=0.031). The coronal and sagittal improvement rates of deformity after traction in group A were 40.47%±3.60% and 40.70%±4.20%, respectively. There was no significant difference between the two groups ( P>0.05) in the coronal and sagittal Cobb angles at 10 days after operation and at last follow-up, in the correction rate of deformity after operation, and in the loss rate of correction at last follow-up. Conclusion For the severe rigid spinal deformity, Halo-pelvic traction with posterior spinal osteotomy and simple posterior spinal osteotomy can obtain the same orthopedic effect and postoperative deformity correction. However, the Halo-pelvic traction can shorten operation time, reduce blood loss and incidence of perioperative complications.

Severe adolescent idiopathic scoliosis: posterior staged correction using a temporary magnetically-controlled growing rod. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2020; 29:2046-2053. [PMID: 32506163 DOI: 10.1007/s00586-020-06483-8] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Revised: 05/14/2020] [Accepted: 05/27/2020] [Indexed: 10/24/2022]
Abstract
PURPOSE A two-staged posterior correction, using a temporary magnetically controlled growing rod (MCGR), was employed to gradually and safely correct severe adolescent idiopathic scoliosis (AIS). The aim of the study is illustrating the results of this procedure. METHODS A retrospective review of a consecutive series of 17 severe AIS. The first surgery was a posterior release (multiple Ponte osteotomies) with implant of pedicle screws and MCGR on the concave side of the curve. In post-operative days, a distraction was applied with MCGR, which allowed to obtain a total mean lengthening of 2 cm in about 2 weeks, with no complications arising. In the second posterior surgery, MCGR was removed and the definitive rods were applied for final fusion. The mean pedicle screws density was 93.3% (85-100). The extension of the final posterior fusion-instrumentation was of 13.8 levels (12-15). RESULTS At an average follow-up (FU) of 2.9 years, the main scoliosis curves from average pre-operative Cobb angle of 98.2° (91°-138°) bent down to 38.3° (35°-76°) after definitive fusion (p < 0.05); at last FU, the overall correction was 58.7% (50.4-71.2), with an average correction loss of 2.1° (1.5°-3.1°). At last FU, no complications were reported. CONCLUSIONS Gradual traction with MCGR in severe AIS proved to be a safe method to achieve progressive curve correction before posterior final fusion, with no neurologic complications associated to more aggressive one-stage surgeries. In a staged approach, MCGR appears as an alternative to halo traction, avoiding frequent traction-related complications.

Abstract
OBJECTIVE To investigate the efficacy and safety of preoperative halo-gravity traction and 1-stage posterior surgery for the treatment of scoliosis with intramedullary anomalies. METHODS A total of 11 patients with scoliosis with intramedullary anomalies were evaluated. All patients were treated with preoperative halo-gravity traction and 1-stage posterior surgery. The average age was 11.4 years (range, 7-21 years). All patients were followed-up for at least 2 years (mean, 3.5 years; range, 2-5 years). Their radiologic presentations and complications were reviewed. RESULTS The operating time was 7.9 hours, and the intraoperative bleeding amount was 1890 mL. Both the Cobb angle of scoliosis and kyphosis were significantly improved after halo-gravity traction and the operation (P < 0.05). Tethered cords were released, and intraspinal masses (neurofibromatosis and lipoma) were excised. Syringomyelia and split spinal cord malformations were left untreated. None of the patients experienced deterioration in their neurologic status after surgery. No severe complications, such as infection, cerebrospinal fluid leakage, failed internal fixation, or fractured pedicle screws or rods occurred after the operation. There was no deterioration of neurologic function, delayed infection, or pseudoarthrosis during the follow-up visits. CONCLUSIONS Preoperative halo-gravity traction and 1-stage posterior surgery provided patients who had scoliosis and intramedullary anomalies an effective and safe treatment option with few complications.

Abstract
OBJECTIVE Halo-gravity traction (HGT) is an effective and safe method for gradual correction of severe cervical deformities in adults. However, the literature is limited on the use of HGT for cervical spine deformities that develop in children. The objective of the present study was to evaluate the safety and efficacy of HGT for pediatric cervical spine deformities. METHODS Twenty-eight patients (18 females) whose mean age was 11.3 ± 5.58 years (range 2-24.9 years) underwent HGT. Common indications included kyphosis (n = 12), rotatory subluxation (n = 7), and basilar invagination (n = 6). Three children (11%) received traction to treat severe occipitocervical instability. For these 3 patients, traction combined with a halo vest, with bars attached rigidly to the vest, but with the ability to slide through the connections to the halo crown, was used to guide the corrective forces and moments in a specific and controlled manner. Patients ambulated with a wheelchair or halo walker under constant traction. Imaging was done before and during traction to evaluate traction efficacy. The modified Clavien-Dindo-Sink classification was used to categorize complications. RESULTS The mean duration of HGT was 25 days (IQR 13-29 days), and the mean traction was 29% ± 13.0% of body weight (IQR 19%-40% of body weight). The mean kyphosis improved from 91° ± 20.7° (range 64°-122°) to 56° ± 17.6° (range 32°-96°) during traction and corresponded to a mean percentage kyphosis correction of 38% ± 13.8% (range 21%-57%). Twenty-five patients (89%) underwent surgical stabilization, and 3 patients (11%) had rotatory subluxation that was adequately reduced by traction and were treated with a halo vest as their definitive treatment. The mean hospital stay was 35 days (IQR 17-43 days).Nine complications (32%) occurred: 8 grade I complications (28%), including 4 cases of superficial pin-site infection (14%) and 4 cases of transient paresthesia (14%). One grade II complication (4%) was seen in a child with Down syndrome and a preexisting neurological deficit; this patient developed flaccid paralysis that rapidly resolved with weight removal. Six cases (21%) of temporary neck discomfort occurred as a sequela of a preexisting condition and resolved without treatment within 24-48 hours. CONCLUSIONS HGT in children is safe and effective for the gradual correction of cervical kyphosis, atlantoaxial subluxation, basilar invagination, and os odontoideum. Cervical traction is an additional tool for the pediatric spine surgeon if uncertainties exist that the spinal alignment required for internal fixation and deformity correction can be safely achieved surgically. Common complications included grade I complications such as superficial pin-site infections and transient paresthesias. Halo vest gravity traction may be warranted in patients with baseline neurological deficits and severe occipitocervical instability to reduce the chance of catastrophic movement.

Abstract
Background: Management of severe scoliotic deformities is challenging. Deformity correction may need three column osteotomies that may be associated with significant morbidity. Staged procedure and use of Halo gravity traction is a useful strategy in such cases.Case Description: A thirty-year-old woman presented with complaint of progressive deformity over the back for the past few years. She was very frail as per the adult spine deformity frailty index (ASD-FI), and her BMI was less than 18. Her Cobb angle measured 180 degrees of main thoracic curve. Her pulmonary function was compromised and had dyspnea on exertion. Management options in these deformities are limited and fraught with risk of major complications. To correct these deformities, a 2-3 level vertebral column resection (VCR) is required using an all-posterior approach. This patient was treated by anterior release followed by halo-gravity traction (HGT) for two weeks, which was then followed by posterior release and correction. The Cobb angle was reduced from 180° to 55° at final follow up of 2 years.Conclusion: Anterior release and traction can help in obviating the vertebral column resection in these severe rigid U-shaped deformities.

Abstract
STUDY DESIGN Retrospective case series. OBJECTIVE To assess the efficacy of preoperative halo-gravity traction (HGT) in the treatment for severe adult kyphosis and scoliosis. Preoperative HGT improves severe curve magnitude and clinical condition in pediatric spinal deformity. However, the efficacy of HGT on severe adult spinal deformity has rarely been studied. MATERIALS AND METHODS This study included 18 patients with severe adult kyphosis and scoliosis (age ≥ 18) who underwent a preoperative HGT (mean 4 weeks), and subsequent definitive posterior-alone corrective fusion. Etiologies were neurofibromatosis (n = 5), adult idiopathic (n = 3), multiple vertebral fractures due to osteoporosis (n = 1) and multiple myeloma (n = 1), degenerative failed back syndrome (n = 1), Scheuermann kyphosis (n = 1), Marfan syndrome (n = 1), and other genetic and connective tissue disorders (n = 5). We reviewed baseline demographics, including coronal and sagittal radiographic profiles. The changes in major curve magnitude, pulmonary function tests (PFTs), and nutritional status were assessed between pre- and post-traction and immediate post-definitive corrective surgery. RESULTS There were 11 male and 7 female patients, aged 18-69 years with their major coronal and sagittal curves being 92.0° ± 25.2° and 111.6° ± 40.1°, respectively. The major coronal and sagittal curves were reduced by 18.4% and 16.8% after halo-traction, and 54.7% and 44.2% after definitive fusion, respectively. PFTs showed significant increase in %FEV1 and %FVC when comparing pre- and post-traction [43.0% ± 17.4% vs. 49.6% ± 18.7%, and 44.8%. ± 16.7% vs. 54.3% ± 20.7%, respectively, p < 0.01 (n = 11)]. Effective weight gain was observed after traction (46.8 ± 14.5 vs. 49.3 ± 13.5 kg, p < 0.01). CONCLUSION Halo-gravity traction (HGT) for severe coronal and sagittal plane spinal deformity in adult patients significantly reduced Cobb angles, improved PFTs, and allowed for effective weight gain in the preoperative period. The use of preoperative HGT is extremely beneficial to optimize the alignment and overall health of severe adult spinal deformity patients before their spinal reconstruction.

Abstract
Correction of severe spinal deformity is a significant challenge for spinal surgeons. Although halo-gravity traction (HGT) has been shown to be well-tolerated and safe, we report here a case of neurologic decline during treatment. A 24-year-old male presents with severe thoracic kyphoscoliosis with > 180° of 3-dimensional deformity. Magnetic resonance imaging showed his thoracic spinal cord draped across his T7-9 apex. His neurologic exam showed lower extremity myelopathy. During week 7 at a goal traction weight of 18.1 kg, his distal lower extremity exam declined from 4+/5 to 2/5. His traction weight was lowered to 11.3 kg. He subsequently sustained a ground-level fall and became paraparetic with a motor exam of 1-2/5. He subsequently underwent a T1-L4 posterior spinal instrumentation and fusion with a T7-9 vertebral column resection. Postoperatively, he was noted to have a complete return to his baseline neurologic exam. At his 4-month postoperative visit, he was now full strength in his lower extremities with complete resolution of his myelopathy. We present here a case of neurologic decline in a patient with severe kyphoscoliosis who underwent HGT and discuss the management decisions associated with this challenging scenario.

Abstract
ABSTRACT Objective: This study aims to compare the use of halo-gravity traction (HGT) with and without previous anterior release, in terms of curve reduction, for the treatment of pediatric severe spinal deformity. Methods: From 2010 to 2016, all patients treated with HGT prior to instrumentation for scoliosis and kyphoscoliosis were reviewed. They were assessed by deformity etiology, previous anterior release, instrumentation procedure used, traction protocol, major Cobb angle before traction, after the protocol, and after the instrumentation procedure. Twelve patients met these criteria and constituted the sample groups: Group I (n=7) with anterior release and Group II (n=5) without anterior release. Results: The average pre-traction major curve Cobb angles were 114.9o and 108.4º for Group I and II, respectively (P>0.05). After HGT, both groups achieved a significant reduction in curve angle (P<0.05). Group I presented an average Cobb angle of 95.0o after HGT, representing a 17.3% (19.8o) curve reduction. Group II presented a Cobb angle of 80.1o, representing a 25.2% (28.4o) curve reduction. The difference between the two groups in relation to the reduction of major curve after HGT was not statistically significant (P=0.073). After the surgical procedure, the correction achieved was significantly improved (P<0.05), without statistically significant difference between the two groups (P>0.05). No major HGT related complications were reported. Conclusions: Anterior release prior to HGT did not increase major curve correction after posterior surgery for severe pediatric idiopathic and syndromic scoliosis. HGT is an effective and safe technique, though it frequently presents minor and transitory complications. Level of Evidence III; Retrospective Comparative Study.

Abstract
Severe rigid neuromuscular scoliosis is a major challenge to the spine surgeon due to the possibilities of neurological sequelae from acute correction of the deformity. Halo gravity traction has been considered as a way of reducing the deformity before correction to prevent neurological complications. Three female patients with severe neuromuscular scoliosis aged seven to 13 years with main coronal Cobb angle of 95°-128° and Kyphotic Cobb of 47°-118° having ≤35% flexibility on traction, had between 18 to 23 days of 16 hour/day of halo gravity traction and night time supine traction with 4kg weight for 7-8 hours. They had 28.9% and 18.5% of main coronal and kyphotic Cobb angle correction post-traction respectively. All had posterior instrumentation and post-operatively, they had correction of main coronal Cobb angle of 29°-58° and kyphotic Cobb angle of 30°-77° with no neurological complication. Halo gravity traction is therefore a viable option for reducing post-operative neurological complication in rigid severe scoliosis.

Abstract
BACKGROUND It is a great challenge for spine surgeons to correct severe rigid scoliosis. We developed a three- staged correction (one stage posterior release and screw placement, two stage skull-femoral traction and three stage posterior instrumentation) for adult severe scoliosis. The objective of this study is to investigate safety and efficacy of a three- staged correction for adult severe scoliosis. METHODS A retrospective review was performed for patients with severe scoliosis receiving three- staged correction (one stage posterior release and screw placement, two stage skull-femoral traction and three stage posterior instrumentation) from June 2001 to October 2014. The inclusion criteria were as follows: [1] age more than 18 years; [2] main curve larger than 90°; [3] a minimum 2-year follow-up. Patients were excluded if they had a history of surgery or anterior release or receiving three column osteotomies. RESULTS A total of 63 patients were included (37 female and 26 male), with a mean age of 22.7 years (range: 18-30 years) and follow-up of 42.6 months (range: 24-108 months). The aetiology was congenital in 27 patients, neuromuscular in 18, idiopathic in 11, neurofibromatosis-1 in 4 and Marfan syndrome in 3. The mean traction weight was 28.4 kg (range: 18-32 kg), equal to 57.2% of patients' body weight (range: 42.7-72.3%). The mean traction time was 22.7 days (range: 12-44 days). Postoperative correction rate was 55% (range: 38-78%) for scoliosis and 51% (range: 32-75%) for kyphosis. Contribution of traction to correction was 51% (range: 36-70%) for scoliosis and was 43% (range: 34-55%) for kyphosis. CONCLUSIONS Three- staged correction (one stage posterior release and screw placement, two stage skull-femoral traction and three stage posterior instrumentation) could effectively correct adult severe scoliosis. The incidence of complications of skull-femoral traction was not low, but transient and could be successfully managed.

Abstract
Adolescent idiopathic scoliosis (AIS) is a complex 3D deformity of the spine. Its prevalence is between 2% and 3% in the general population, with almost 10% of patients requiring some form of treatment and up to 0.1% undergoing surgery. The cosmetic aspect of the deformity is the biggest concern to the patient and is often accompanied by psychosocial distress. In addition, severe curves can cause cardiopulmonary distress. With proven benefits from surgery, the aims of treatment are to improve the cosmetic and functional outcomes. Obtaining correction in the coronal plane is not the only important endpoint anymore. With better understanding of spinal biomechanics and the long-term effects of multiplanar imbalance, we now know that sagittal balance is equally, if not more, important. Better correction of deformities has also been facilitated by an improvement in the design of implants and a better understanding of metallurgy. Understanding the unique character of each deformity is important. In addition, using the most appropriate implant and applying all the principles of correction in a bespoke manner is important to achieve optimum correction. In this article, we review the current concepts in AIS surgery. Cite this article: Bone Joint J 2018;100-B:415–24.

Abstract
INTRODUCTION There is high risk of neurologic complications in one-stage management of severe rigid spinal deformities in adolescents. Therefore, gradual spine stretching variants are applied. One of them is the use of external transpedicular fixation. PURPOSE Our aim was to retrospectively study the outcomes of gradual correction with an apparatus for external transpedicular fixation followed by internal fixation used for high-grade kyphoscoliosis in adolescents. METHODS Twenty five patients were reviewed (mean age, 15.1 ± 0.4 years). Correction was performed in two stages: 1) gradual controlled correction with the apparatus for external transpedicular fixation; and 2) internal posterior transpedicular fixation. Rigid deformities in eight patients required discapophysectomy. Clinical and radiographic study of the outcomes was conducted immediately after treatment and at a mean long-term period of 3.8 ± 0.4 years. Pain was evaluated using the visual analogue scale (VAS, 10 points). The Oswestry questionnaire (ODI scale) was used for functional assessment. RESULTS Deformity correction with the external apparatus was 64.2 ± 4.6% in the main curve and 60.7 ± 3.7% in the compensatory one. It was 72.8 ± 4.1% and 66.2 ± 5.3% immediately after treatment and 70.8 ± 4.6% and 64.3 ± 4.2% at long term, respectively. Pain relieved by 33.2 ± 4.2% (p < 0.05) immediately after treatment and by 55.6 ± 2.8% (p < 0.05) at long term. ODI reduced by 30.2 ± 1.7% (p < 0.05) immediately after treatment and by 37.2 ± 1.6% (p < 0.05) at long term. CONCLUSION The apparatus for external transpedicular fixation provides gradual controlled correction for high-grade kyphoscoliosis in adolescents. Transition to internal fixation preserves the correction achieved, and correction is maintained at long term.

Abstract
Background This study investigated the outcomes of preoperative HGT as an adjunct treatment for severe thoracic kyphoscoliosis, its role in radiographic correction, and pulmonary function improvement, together with nursing strategy and incidence of complications. Material/Methods Eleven patients with a mean age of 18.8 years were retrospectively reviewed. Inclusion criteria were: patients with severe kyphoscoliosis (coronal Cobb angle and kyphosis angle ≥80°); duration of HGT ≥8 weeks; patients undergoing HGT for at least 12 h per day; traction weight no less than 40% of body weight; and patients not receiving physical therapies. All patients underwent respiratory training. Results The major coronal curve scoliosis averaged 114.00±24.43° and was reduced to 80.55±17.98° after HGT. The major kyphosis was 103.91±18.95° and was reduced to 80.55±17.98°. Significantly improved percent-predicted values for FVC was found after HGT (p=0.014), and significantly increased forced expiratory volume in 1 s (FEV1%) was also observed (p<0.001), with significantly improved percent-predicted values for PEF (p=0.003) after HGT. Conclusions Our data reveal that preoperative HGT can be performed safely, and can help achieve excellent curve correction in both the coronal and sagittal planes, together with improved respiratory function and no severe complications in patients with severe thoracic kyphoscoliosis.
