Purpose: Feeding difficulties are common among patients with cerebral palsy (CP) and neuromuscular (NM) scoliosis. We theorize that posterior spinal fusion (PSF) reduces intra-abdominal pressure, resulting in improved feeding and subsequent weight gain. We hypothesized that, among nonambulatory patients with CP and NM scoliosis, we would observe significant gain in weight following PSF. Methods: Fifty subjects with nonambulatory CP who underwent PSF for NM scoliosis were included. Age and weight were recorded for the preoperative year; on the day of surgery; and at 6-month, 1-year, and 2-year follow-up. Weights were converted to weight percentiles using CP-specific growth charts. The weight percentile distributions were compared between time points using descriptive statistics as well as regression analysis. Results: The average change in weight from the day of surgery to 2-year follow-up was +3.4 percentiles. Patients who started out under the 50th percentile gained an average of 17.3 percentiles in the first year after PSF ( p = 0.009). Regression analysis showed that patients with baseline weight <50th percentile tended to gain in weight percentile over the first postoperative year ( β = 1.990, p = 0.001). No trend was present among this group prior to surgery ( p = 0.692) or during the second postoperative year ( p = 0.945). No trends were noted prior to or after surgery for patients with baseline weights ≥50th percentile. No significant association was observed between curve severity (measured by preoperative Cobb angle) and weight change. Conclusions: This series is the first to document significant weight gain after PSF for NM scoliosis, supporting the theory that spinal correction improves digestive function. Level of Evidence: Prognostic level II.

ABSTRACT Introduction: The effect of spinal fusion on gait in patients with neuromuscular scoliosis continues to be a controversial issue, especially in patients where the spinal fusion extends to the pelvis. Objective: To evaluate the effect of spinal instrumentation in these patients. Methods: We evaluated 34 patients in a retrospective study. The mean age at surgery was 14±3 years and only ambulatory patients who presented neuromuscular scoliosis and non-progressing neurogenic pathology were included. The patients were surgically treated by posterior spinal fusion with or without extension to the pelvis. Preoperative (PRE) and postoperative (POP) Rx were measured. Ambulatory potential was clinically examined in all the patients, and 10 patients were assessed by full-gait analysis. Results: The minimum POP follow-up was 2 years (2006-2016). Nine patients were instrumented to the pelvis when the obliquity was greater than 15°; the remaining patients were treated using the same fusion-level criteria as those applied for idiopathic scoliosis. All patients maintained their gait, with improvements in coronal and sagittal balance, transfers and sitting skills, physical appearance, and in some cases, gait speed. Conclusions: Spinal instrumentation in ambulatory patients with neuromuscular scoliosis, including procedures with extension to the pelvis, provides adequate correction and preserves ambulatory function.

Sublaminar Bands

Purpose Multiple fixation techniques exist for treating progressive neuromuscular scoliosis including pedicle screws, sublaminar bands/wires, hooks or a combination of instruments. Most sublaminar band constructs are supplemented with pedicle screws, hooks and/or sublaminar wires particularly at the top of the construct. There are no studies to date that describe an all/predominant sublaminar band construct. The purpose of this study was to investigate the outcomes of a sublaminar polyester band construct to treat neuromuscular scoliosis. Methods A retrospective review was conducted of 32 cases of neuromuscular scoliosis treated with posterior spinal fusion using a sublaminar band construct between 2013 and 2016 by a single surgeon at a single centre. Preoperative, immediate postoperative and two-year follow-up radiographs and clinical records were reviewed. Sagittal, coronal and pelvic obliquity correction was measured. Blood loss, length of surgery and complications were recorded. Results In all, 29 patients were included. Mean postoperative coronal plane correction was 57% (0% to 92%) and maintained at two-year follow-up. Mean sagittal balance was 2.3 cm (-2.5 to 6.4). Mean lumbar lordosis angle decreased by 7° (44° to 37°). Mean thoracic kyphosis angle increased by 9° (23° to 32°). Mean pelvic obliquity decreased by 50% (from 15° to 7°). There were four major complications (14%) and eight minor complications (21%). Mean blood loss was 1304 cc (250 cc to 2450 cc). Conclusion Sublaminar polyester band fixation constructs provide a viable option in correction of deformity in patients with neuromuscular scoliosis with comparable outcomes with what is reported with other constructs.

Abstract Purpose: To investigate Hidden blood loss (HBL) and its potential risk factors in adolescent idiopathic scoliosis patients undergoing posterior spinal fusion surgery and elucidate the influence of HBL on postoperative blood transfusion. Methods: We retrospectively studied 765 patients undergoing posterior spine fusion for adolescent idiopathic scoliosis from January 2014 to December 2018. The patient’s demographics, blood loss related parameters, operation and blood loss information were extracted. The association between patient’s characteristics and HBL was analyzed by Pearson or Spearman correlation analysis. Multivariate linear regression analysis was used to determine independent risk factors associated with HBL. Binary logistic regression analysis was used to analyze the influence of HBL on postoperative blood transfusion.Results: A total of 765 patients including 128 males and 637 females (age range 10-18 years) were included in this study. The mean amount of HBL was 693.5±473.4 ml, accounting for 53.9% of the total blood loss. In multivariate linear regression analysis, we found that preoperative Hct (p=0.003) and allogeneic blood transfusion (p<0.0001) were independent risk factors for HBL, while tranexamic acid (p=0.003) was negatively related to HBL. Binary logistic regression analysis showed that HBL > 850 ml ( P < 0.001, OR: 8.845, 95%CI: 5.806-13.290) was the independent risk factor for postoperative blood transfusion.Conclusion: a large amount of HBL was incurred in adolescent idiopathic scoliosis patients undergoing posterior spinal fusion surgeries. Allogeneic blood transfusion and preoperative Hct were independent risk factors for HBL, while tranexamic acid was negatively related to HBL. HBL and its influential factors should be taken into account when considering the perioperative transfusion management. These patients with HBL greater than 850 ml should be paid more attention in case of postoperative anemia.Level of evidence: Level III

Abstract Background: The mid-long term outcomes of posterior spinal fusion in pediatric neurofibromatosis type 1 (NF-1) patients are rarely reported, so does the effectiveness of itsorthopeidc maintenance function. This study aims to evaluate the mid-long term surgical outcomes of posterior only instrumented spinal fusion for early-onset scoliosis (EOS) in NF-1 patients. Methods: A retrospective review was performed on a cohort of 10 NF-1 patients having EOS from 2008 to 2014 in our hospital, including four male and six female patients with an age averaged at 7.8 years old when they underwent posterior only instrumented spinal fusion for their EOS. Both general clinical data and surgical specific data of the patients were collected and reviewed, and the dystrophic progression of EOS was evaluated during the follow-up. Results: The average duration of follow-up was 54 months (24 to 88 months). All patients underwent posterior only instrumented spinal fusion at 1 stage. The primary curves of EOS were thoracic in 9 cases and 1 patient had lumbar scoliosis. Preoperative major curve was significantly corrected (from 66.1 to 31.1 degrees). However, the major curve deteriorated significantly to 40.1 degrees on average at the end of the follow-up. The T1-S1 distance increased 2.8 cm on average and kept increasing at a rate of 0.6cm/year during the follow-up. Conclusions: Posterior only fusion surgery was not a good option to treat the EOS in NF-1 patients despite the relatively short segments involvement in the disease. The maintenance of orthopedic effect after treatment was not satisfactory.

Laboratory Findings

Introduction: Spinal tuberculosis has been managed with various modalities of treatment ranging from only antituberculous drugs to radical surgical extirpation. Opinion is divided on management of Potts Paraplegia with respect to surgical approach to the lesion. Results are conflicting on anterior verses posterior approaches as well combined approach. There is also confusion on to when to do anterior first or to operate from posterior first, in combined approaches. In the present study we present 10 year follow-up of our results, clinical and radiological outcomes, of Single stage Circumspinal decompression and pedicle screw fixation through lateral extracavitatory approach with anterior and posterior spinal fusion in cases of Pott's paraplegia. Methods:The study was a retrospective and prospective follow up of 30 patients with active tuberculosis of thoracolumbar spine with neurological deficit, who underwent posterior spinal instrumentation with lateral extra cavitatory approach with circumspinal decompression and pedicle screw instrumentation. Diagnosis of spinal tuberculosis was made by laboratory findings such as anaemia, elevated ESR, radiological features with typical MR imaging findings. 8 patients had multilevel involvement. Kyphosis of 250 to 550 was present. Circumspinal decompression, correction of kyphosis, anterior and posterior spinal fusion was performed in a single stage. The average follow up was 7.67 years (92 months). Results: The mean kyphosis angle improved from 320 preoperatively to 80 in early follow up, followed by a minor loss of correction of 30. Neurological recovery occurred in 28 patients out of 30 patients. 15 patients recovered from Asia A to AIS E. 13 patients recovered to ASIA D. The visual analog scale and ASIA grade improved in all the cases. Implant failure in the form of rod breakage was seen in 1 patient but with no neurological complications. Conclusion: Drainage of abscess, debridement by extracavitatory route constitutes a less demanding, relatively safe, minimally traumatic operative technique with adequate circumspinal decompression of spinal cord, correction and maintenance of sagittal balance with relatively less morbidity is the added advantage.
