Purpose: Neurological deficits developing years after pedicle screw misplacement is a rare phenomenon. Here, we report level IV evidence of a previously asymptomatic medial thoracic pedicle screw resulting in paraparesis after a motor vehicle accident.
Methods: A 21-year-old male presented with acute onset of paraparesis following a motor vehicle collision. Six years prior this incident, the patient underwent a thoracolumbar fusion T4-L4 for AIS performed by an outside orthopedic surgeon. CT scan and CT myelogram illustrated decreased spinal canal diameter and cord compression from a medial T8 pedicle screw.
Results: Surgical removal of the misplaced pedicle screw resulted in a gradual complete recovery sustained over a period of 2 years. This case is compared to those reported in the literature review between 1981 and 2019 concerning delayed neurological deterioration related to misplaced pedicle screw.
Conclusion: This case reports a delayed neurological deficit implicating a misplaced pedicle screw. This phenomenon remains rare since 5 cases were reported in the literature over the last 4 decades. It calls into focus the need for confirmation of safe instrumentation during the intraoperative period. It also illustrates the potential difficult decision-making in regard to asymptomatic misplaced instrumentation.
Level of evidence: IV.
目的:椎弓根螺钉错位多年后出现神经功能缺损是一种罕见现象。在此,我们报告了在一起机动车事故后,先前无症状的内侧胸椎椎弓根螺钉导致截瘫的 IV 级证据:一名 21 岁的男性患者在一次机动车碰撞后出现急性截瘫。事故发生六年前,该患者因AIS接受了由外院骨科医生实施的胸腰椎T4-L4融合术。CT扫描和CT脊髓造影显示,T8内侧椎弓根螺钉导致椎管直径减小和脊髓受压:手术取出错位的椎弓根螺钉后,患者在两年内逐渐完全康复。本病例与1981年至2019年文献综述中报道的与椎弓根螺钉错位相关的延迟性神经功能衰退病例进行了比较:本病例报告了与椎弓根螺钉错位有关的延迟性神经功能缺损。过去 40 年间,文献中仅报道了 5 例,因此这种现象仍然十分罕见。该病例强调了在术中确认器械安全的必要性。它还说明了在无症状的错位器械方面潜在的决策困难:证据等级:IV。

Purpose: It aims to investigate the lumbar and pelvic morphology in congenital scoliosis with thoracolumbar hemivertebrae and its impact on proximal junctional kyphosis (PJK) incidence after hemivertebra resection and short fusion.
Methods: 23 congenital scoliosis patients with thoracolumbar hemivertebra aged between 10 and 18 years were enrolled in the retrospective study. Spinopelvic sagittal parameters were analyzed on whole-spine standing lateral radiographs preoperatively, one-week postoperatively and at the final follow-up. Pearson correlations were calculated for local kyphosis (LK), lumbar and pelvic morphology parameters. Binary logistic regression and receiver operating characteristics (ROC) curve analysis were performed to identify the risk factors for PJK.
Results: Thoracolumbar hemivertebra caused LK of 29.2° ± 17.3°, an increased lumbar lordosis (LL) (-64.7° ± 16.3°), lower LL apex (52.2% at L5), and small pelvic incidence (PI) (36.8° ± 6.6°). LK was correlated with lumbar morphology parameters, including LL (r = - 0.837), upper arc of LL (LLUA) (r = - 0.879), thoracolumbar kyphosis (TLK) (r = 0.933), thoracic kyphosis (TK) (r = 0.762) and TK apex (TKA) (r = - 0.749). Surgical treatment improved the lumbar morphology, but not pelvic morphology. At the final follow-up, LL had returned to its preoperative value (p = 0.158). PJK occurred in 30.4% of cases as a compensatory mechanism. Preoperatively, significant differences of parameters between non-PJK and PJK groups were observed in LK and TLK. Binary logistic regression identified three independent risk factors for PJK: preoperative LLA (OR = 0.005, 95%CI = 0.000-0.287, p = 0.011), preoperative TLK (OR = 1.134, 95%CI = 1.001-1.286, p = 0.048), and preoperative lumbar lordosis morphology type (OR = 5.507, 95%CI = 1.202-25.227, p = 0.028). However, residual LK after surgery was not correlated with PJK incidence. ROC curve analysis verified that preoperative TLK > 22.59° was associated with increased PJK incidence after surgery.
Conclusions: Lumbar morphology changes as a compensatory mechanism beneath the thoracolumbar hemivertebra. However, a stable pelvis tends to allow the LL to return to its preoperative value. PJK occurred as a cranial compensatory mechanism for increasing LL and corrected TLK. A larger TLK (> 22.59°) was an independent risk factor for PJK incidence in patients with type 2 and 3A lumbar lordosis morphology.

Aim: The objective of this study was to evaluate the safety and efficacy of a novel technique of formal reduction and circumferential fusion for pediatric high-grade spondylolisthesis (HGS).
Purpose: The safety and efficacy of formal reduction for high-grade spondylolisthesis (HGS) has never been thoroughly examined. This study reports the outcomes of 29 children with HGS who underwent a procedure of gradual reduction and circumferential fusion.
Methods: 29 children (13 males, 16 females) were recruited between 2006 and 2010. Radiographic measurements (including % of slip, lumbosacral angle-LSA, pelvic incidence-PI, pelvic tilt-PT, sacral slope-SS, and proximal femoral angle-PFA) and quality of life assessment (SRS-22 questionnaire) were prospectively obtained at baseline and at the last post-operative follow-up (> 2 years post-op). Radiological measurements were used to classify patients according to the Spine Deformity Study Group (SDSG) classification.
Results: Mean baseline slip % was 69.9 ± 16.5%. There were 13 patients with a balanced pelvic (SDSG Type 4) and 16 with an unbalanced pelvis (SDSG Type 5 and 6). On average, a reduction of 45.5 ± 15.3% (range 20-86%) was achieved safely with no major complication. In particular, of the 29 patients, only 3 had a L5 radiculopathy postoperatively that was self-resolved at follow-up. From a radiological standpoint, we observed a mean improvement of LSA from 80.3 ± 17.9° to 91.7 ± 13.6°. We also observed a statistically significant improvement in global HRQOL, and in the function and body image domains.
Conclusion: This prospective study suggests that formal reduction of HGS followed by circumferential fusion is safe when using a standardized surgical technique based on gradual reduction. Performing this intervention could also help improve QOL in some patients.

Purpose: To review the current literature surrounding the assessment of self-image in pediatric and adult spinal deformity.
Methods: The literature were reviewed for studies examining patient-reported outcome measurements (PROM) and self-image in pediatric and adult spinal deformity. PROM performance metrics were collected and described. The relationships between self-image PROM and patient outcomes, including satisfaction, were described.
Results: Several self-image PROM exist, including the Scoliosis Research Society-22r (SRS-22r) self-image domain, the Body Image Disturbance Questionnaire (BIDQ), and the Spinal Appearance Questionnaire (SAQ). The most commonly used is the self-image domain of the SRS-22r. It is validated in adult and pediatric spinal deformity and is correlated with patient desire for surgery and satisfaction after surgery. This domain is limited by floor and ceiling effects.
Conclusion: Self-image assessment is critical to both pediatric and adult spinal deformity surgeries. The SRS-22r self-image domain is the most frequently reported PROM for this health domain. While valid in both surgical cohorts, this PROM is affected by floor and ceiling effects which limits the ability to discriminate between health states. Given the overall importance of this domain to patients with spinal deformity further efforts are needed to improve discrimination without gross increases in PROM question burden, which may limit broad acceptance and use.

Purpose: Preoperative counting of thoracic and lumbar vertebrae is crucial in adolescent idiopathic scoliosis (AIS) due to reported anatomical variations and potential surgical site misidentification. This study investigated characteristics associated with the vertebral number variations AIS, particularly focusing on rib morphology.
Methods: Based on three-dimensional computed tomography, patients were categorized into the non-variant number group, comprising individuals with 12 thoracic and 5 lumbar vertebrae, and the variant number group, comprising individuals with different numbers of vertebrae. Additionally, the most caudal rib morphology was classified as normal, unilateral, or hypoplastic.
Results: A total of 359 patients were included in our study (41 males, 318 females, age: 16.3 ± 3.1 years), with 44 patients (12.3%) assigned to the variant number group. Logistic regression analysis identified unilateral ribs (odds ratio [OR]: 10.50) and lumbosacral transitional vertebrae (LSTV) (OR 6.49) as significant risk factors associated with variations. Further analysis revealed hypoplastic ribs as a significant risk factor associated with LSTV (OR: 4.58). 8 CONCLUSION: Our study suggests that abnormal rib morphology may be associated with vertebral number variations. Close attention to rib morphology is, therefore, warranted in cases with atypical vertebral numbers. Accordingly, to ensure surgical safety and accuracy, spine surgeons must communicate these variations to the surgical team, standardize nomenclature for describing them, and intraoperatively verify fusion levels with them.

Purpose: To perform a cross-cultural adaptation and validation of the Brazilian-Portuguese versions of the Brace Questionnaire in adolescent idiopathic scoliosis.
Methods: A forward-backward translation process was employed to produce a Brazilian Portuguese version of the Brace Questionnaire, followed by comprehensive cross-cultural adaptation stages. The measurements of internal consistency and test-retest reliability were assessed by Cronbach's a and intraclass correlation coefficient (ICC), respectively. The Pearson's correlation coefficient was used to analyze the concurrent validity by comparison with the Scoliosis Research Society-22r questionnaire.
Results: A total of 84 scoliosis patients (age 13.4 ± 2.0 years, thoracic Cobb angle 33.3° ± 13.8°, and lumbar Cobb angle 29.8° ± 14.3°) were included. The Brace Questionnaire showed excellent internal consistency (Cronbach α = 0.93) and moderate reliability (ICC = 0.86). The correlations between the Brace Questionnaire and Scoliosis Research Society-22 were r = 0.66; p = 0.011. In addition, it was found that the Brazilian version of the Brace Questionnaire does not have ceiling and floor effects.
Conclusions: The Brazilian-Portuguese adaptation of the brace questionnaire shows excellent reliability and can be a valid tool for psychometric assessment in adolescent idiopathic scoliosis.

Purpose: To describe the incidence of reoperation and factors contributing to surgical revision within a minimum of 10 years after spinal fusion for scoliosis in patients with nonambulatory cerebral palsy (CP).
Methods: We conducted a retrospective review of consecutive nonambulatory patients with CP who underwent primary spinal fusion at a single specialty care center with a minimum of 10 years from their index surgery (surgery dates 2001-2011). Causes of reoperation were classified as implant failure/pseudoarthrosis, surgical site infection (SSI), proximal junctional kyphosis, prominent/symptomatic implants, and implant removal. Reoperation rates with 95% confidence intervals were calculated for each time interval, and an actuarial survival curve was generated.
Results: 144 patients met inclusion criteria (mean age = 14.3 ± 2.6 years, 62.5% male); 85.4% had 5 years follow-up data; and 66.0% had 10 years follow-up data. Estimates from the actuarial analysis suggest that 14.9% (95% CI: 10.0-22.0) underwent reoperation by 5 years postsurgery, and 21.7% (95% CI: 15.4-30.1) underwent reoperation by 10 years postsurgery. The most common causes for reoperation were implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants.
Conclusions: To our knowledge, this study is the largest long-term follow-up of nonambulatory patients with CP and neuromuscular scoliosis who underwent spinal fusion. Approximately 22% of these patients required reoperation 10 years after their index surgery, primarily due to implant failure/pseudoarthrosis, SSI, and prominent/symptomatic implants. Complications and reoperations continued throughout the 10 years period after index surgery, reinforcing the need for long-term follow-up as these patients transition into adulthood.

Purpose: To characterize the frequency of incidental dural tears in pediatric spine surgery, their treatment, complications, and results of long-term follow-up.
Methods: A retrospective review of all pediatric patients who underwent a posterior spinal fusion (PSF) between 2004-2019 at a tertiary children's hospital was conducted. Electronic medical records were reviewed for patient demographics, intra-operative data, presence of an incidental dural tear, repair method, and patient outcomes.
Results: 3043 PSFs were reviewed, with 99 dural tears identified in 94 patients (3.3% overall incidence). Mean follow-up was 35.7 months (range 0.1-142.5). When the cause of the dural tear was specified, 69% occurred during exposure, 5% during pedicle screw placement, 4% during osteotomy, 2% during removal of implants, and 2% during intra-thecal injection of morphine. The rate of dural tears during primary PSF was significantly lower than during revision PSF procedures (2.6% vs. 6.2%, p < 0.05). 86.9% of dural tears were repaired and/or sealed intraoperatively, while 13.1% had spontaneous resolution. Postoperative headaches developed in 13.1% of patients and resolved at a mean of 7.6 days. There was no difference in the incidence of headaches in patients that were ordered bedrest vs. no bedrest (p > 0.99). Postoperative infections occurred in 9.5% of patients and 24.1% patients were identified to have undergone a revision surgery.
Conclusions: Incidence of intra-operative dural tears in pediatric spine surgery is 3.3%. Although complications associated with the dural tear occur, most resolve over time and there were no long-term sequelae in patients with 2 years of follow up.

Purpose: Early onset scoliosis (EOS) patient diversity makes outcome prediction challenging. Machine learning offers an innovative approach to analyze patient data and predict results, including LOS in pediatric spinal deformity surgery.
Methods: Children under 10 with EOS were chosen from the American College of Surgeon's NSQIP database. Extended LOS, defined as over 5 days, was predicted using feature selection and machine learning in Python. The best model, determined by the area under the curve (AUC), was optimized and used to create a risk calculator for prolonged LOS.
Results: The study included 1587 patients, mostly young (average age: 6.94 ± 2.58 years), with 33.1% experiencing prolonged LOS (n = 526). Most patients were female (59.2%, n = 940), with an average BMI of 17.0 ± 8.7. Factors influencing LOS were operative time, age, BMI, ASA class, levels operated on, etiology, nutritional support, pulmonary and neurologic comorbidities. The gradient boosting model performed best with a test accuracy of 0.723, AUC of 0.630, and a Brier score of 0.189, leading to a patient-specific risk calculator for prolonged LOS.
Conclusions: Machine learning algorithms accurately predict extended LOS across a national patient cohort and characterize key preoperative drivers of increased LOS after PSIF in pediatric patients with EOS.

Purpose: Postoperative physical therapy (PT) is a cornerstone of orthopedic and musculoskeletal rehabilitation, proven to provide various positive clinical benefits. However, there is a paucity of literature evaluating the utility of preoperative rehabilitation specific to spine surgery. Thus, this review article aims to provide an overview of previously published studies discussing the efficacy of preoperative rehabilitation programs and its role in spinal surgery. Special emphasis was given to preoperative frailty assessments, physical performance tests, interventional strategies, feasibility, and future directions.
Methods: We performed a literature review using PubMed, Google Scholar, EMBASE, and PubMed Central (PMC) using directed search terms. Articles that examined preoperative rehabilitation in adult spine surgery were compiled for this review. Prehabilitation programs focused on exercise, flexibility, and behavioral modifications have been shown to significantly improve pain levels and functional strength assessments in patients undergoing elective spine surgery. In addition, studies suggest that these programs may also decrease hospital stays, return to work time, and overall direct health care expenditure costs. Screening tools such as the FRAIL scale can be used to assess frailty while physical function tests like the timed-up-and go (TUGT), 5 repetition sit-to-stand test (5R-STST), and hand grip strength (HGS) can help identify patients who would most benefit from prehabilitation.
Conclusions: This review illustrates that prehabilitation programs have the potential to increase quality of life, improve physical function and activity levels, and decrease pain, hospital stays, return to work time, and overall direct costs. However, there is a paucity of literature in this field that requires further study and investigation.
目的:术后物理治疗(PT)是骨科和肌肉骨骼康复的基石,已被证实可提供各种积极的临床益处。然而,评估脊柱手术术前康复的文献却很少。因此,这篇综述文章旨在概述之前发表的关于术前康复计划的疗效及其在脊柱手术中的作用的研究。文章特别强调了术前虚弱评估、体能测试、干预策略、可行性和未来发展方向:我们利用 PubMed、Google Scholar、EMBASE 和 PubMed Central (PMC) 进行了文献综述,并使用了定向检索词。本综述汇编了研究成人脊柱手术术前康复的文章。研究表明,以运动、柔韧性和行为矫正为重点的术前康复计划可显著改善脊柱外科择期手术患者的疼痛程度和功能强度评估。此外,研究还表明,这些计划还可以缩短住院时间、重返工作岗位时间和整体直接医疗支出费用。FRAIL量表等筛查工具可用于评估虚弱程度,而定时起立行走(TUGT)、5次重复坐立测试(5R-STST)和手握力(HGS)等身体功能测试可帮助确定哪些患者最能从康复前训练中获益:本综述表明,康复训练计划有可能提高生活质量、改善身体功能和活动水平,并减少疼痛、住院时间、重返工作岗位时间和整体直接成本。然而,该领域的文献还很少,需要进一步研究和调查。
