The reunion with my patients: their journey and experience 30 years after their intervention for adolescent idiopathic scoliosis via CD instrumentation.

PURPOSE: Our objective was to collect the experience and current attitude of those patients, now adults, operated on for adolescent idiopathic scoliosis (AIS) more than 25 years ago with CD instrumentation (CDI). METHODS: Prospective qualitative cross-sectional study with interpretive phenomenological analysis approach of AIS patients operated in a single center with CDI between 1985 and 1995. Patients underwent a semi-structured interview with their original surgeon. Seven agreed themes were open for conversation, and several subthemes emerged related to their experience during their journey in life. Filed notes were recorded and transcribed verbatim. We used the method of content, semantic and pragmatic analysis. RESULTS: We contacted 103 patients, 100 agreed to participate. Mean age was 47.5 ± 3.3, mean follow-up was 30.9 ± 2.7 years. Three fundamental concerns stood out: discomfort with self-image; low back pain with daily activities; and lack of spinal flexibility. 50% were engaged in continuous physical exercise, and only some referred limitations with load-bearing work. Patients commonly described negative memories of the conservative treatment, but positive memories of the surgical process. In general, there was a good adaptation to social life (occupation, social and family relationships). Two-thirds were married, and 65 women had offspring. A frequent concern was the excess of radiographs over the years, and three developed breast cancer. CONCLUSIONS: Factors such as dissatisfaction with self-image, low back pain, and spine stiffness were relevant to patients throughout their journeys. Despite this, the great majority were satisfied with the treatment received, which allowed them to lead an integrated life in society. LEVEL OF EVIDENCE: Level II.

What is the effect of preoperative depression on outcomes after minimally invasive surgery for adult spinal deformity? A prospective cohort analysis.

OBJECTIVE: Depression has been implicated with worse immediate postoperative outcomes in adult spinal deformity (ASD) correction, yet the specific impact of depression on those patients undergoing minimally invasive surgery (MIS) requires further clarity. This study aimed to evaluate the role of depression in the recovery of patients with ASD after undergoing MIS. METHODS: Patients who underwent MIS for ASD with a minimum postoperative follow-up of 1 year were included from a prospectively collected, multicenter registry. Two cohorts of patients were identified that consisted of either those affirming or denying depression on preoperative assessment. The patient-reported outcome measures (PROMs) compared included scores on the Oswestry Disability Index (ODI), numeric rating scale (NRS) for back and leg pain, Scoliosis Research Society Outcomes Questionnaire (SRS-22), SF-36 physical component summary, SF-36 mental component summary (MCS), EQ-5D, and EQ-5D visual analog scale. RESULTS: Twenty-seven of 147 (18.4%) patients screened positive for preoperative depression. The nondepressed cohort had an average of 4.83 levels fused, and the depressed cohort had 5.56 levels fused per patient (p = 0.267). At 1-year follow-up, 10 patients still reported depression, representing a 63% decrease. Postoperatively, both cohorts demonstrated improvement in their PROMs; however, at 1-year follow-up, those without depression had statistically better outcomes based on the EQ-5D, MCS, and SRS-22 scores (p < 0.05). Patients with depression continued to experience higher NRS leg scores at 1-year follow-up (3.63 vs 2.22, p = 0.018). After controlling for covariates, the authors found that depression significantly impacted only 1-year follow-up MCS scores (ß = 8.490, p < 0.05). CONCLUSIONS: Depressed and nondepressed patients reported similar improvements after MIS surgery, except MCS scores were more likely to improve in nondepressed patients.

Heath-related quality of life and functional outcomes in patients with congenital or juvenile idiopathic scoliosis after an average follow-up of 25 years: a cohort study.

BACKGROUND CONTEXT: Congenital and juvenile scoliosis are both early-onset deformities that develop before the age of 10. Children are treated to prevent curve progression and problems in adulthood such as back pain and a decreased quality of life but literature on long-term outcomes remains scarce. PURPOSE: To evaluate the health-related quality of life (HRQoL) and potential disability of children with congenital scoliosis (CS) or juvenile idiopathic scoliosis (JIS) after a minimum of 20 years follow-up. STUDY DESIGN: Comparative cohort study. PATIENT SAMPLE: A consecutive cohort of CS and JIS patients were retrospectively identified from a single-center scoliosis database. Patients born between 1968 and 1981 and treated during skeletal growth were eligible for participation. OUTCOME MEASURES: HRQoL (SF-36, SRS-22r, ODI). METHODS: The primary aim was to evaluate the HRQoL of CS and JIS patients using the general SF-36 questionnaire. Both patient cohorts were compared with age-matched national norms. The secondary aim was to analyze the differences between conservatively and surgically treated patients using the scoliosis-specific Scoliosis Research Society-22r questionnaire (SRS-22r) and the Oswestry Disability Index (ODI). T-tests were used for statistical comparison. RESULTS: In total, 114 patients (67% of the eligible patients) completed the questionnaire, with a mean follow-up of 25.5±5.5 years after their final clinical follow-up. Twenty-nine patients with CS were included with a mean age of 44.4±3.8 years (79.3% female), and 85 patients with JIS with a mean age of 43.7±4.2 years (89.4% female). Of the SF-36 domains, only the vitality score (60.6±18.0 for CS and 58.1±17.6 for JIS cohort) and mental health score (70.0±18.4 for CS and 72.1±18.1 for JIS cohort) were significantly lower compared with the general population (68.6±19.3 for vitality, and 76.8±17.4 for mental health). These decreased scores were larger than the determined minimum clinically important difference threshold of 4.37. Surgically treated JIS patients had a significantly lower score on the SRS-22r pain domain than their nonsurgically treated peers (3.6±0.9 vs 4.1±0.7l p=.019). Surgically treated CS patients had a significantly higher score on the SRS-22r mental health domain than their nonsurgically treated peers (4.3±0.5 vs 3.5±1.0; p=.023). No significant differences were found in the other domains. CONCLUSIONS: Except for vitality and mental health domains, congenital and juvenile idiopathic scoliosis patients treated during skeletal growth had similar HRQoL on most SF-36 domains in adulthood compared with national norms. Surgical treated JIS patients experienced more pain compared with brace treated patients, while braced CS patients had a significantly lower mental scores compared with surgical treated patients. These long-term outcomes are essential to inform patients and can guide shared decision-making between clinicians and patients.

Psychosocial Effect of Brace Treatment in Adolescent Idiopathic Scoliosis: A Study Using EQ-5D.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To evaluate psychosocial effect of brace treatment in adolescent idiopathic scoliosis (AIS) using EuroQoL 5-dimension (EQ-5D) depression and anxiety category. BACKGROUND: AIS is a structural abnormality of the spine often affecting patients during the puberty, a critical period of developing psychosocial problems. Many questionnaires had been adapted to evaluate mental health and health-related quality of life of AIS patients. However, these questionnaires are often time consuming and difficult to obtain. Therefore, a simpler substitute-EQ-5D-was evaluated. METHODS: This is a single-center retrospective cohort analysis of adult idiopathic scoliosis patients aged between 8 and 19, visiting outpatient's clinic. Beck's depression inventory, EQ-5D and EuroQoL visual assessment scale, and Objectified Body Consciousness Scale for Youth were compared between brace group and non-brace group of AIS patients. Furthermore, difference between male and female were evaluated within brace group. RESULTS: None of the questionnaire showed significant difference between brace and non-brace group. However, when male and female patients were compared within brace group, female patients were significantly more susceptible to depression and anxiety based on EQ-5D and body consciousness. Furthermore, depression and anxiety according to both BDI and EQ-5D were significantly correlated to health-related quality of life. CONCLUSION: During brace treatment of female AIS patients, psychosocial status played a significant role in health-related quality of life. EQ-5D is a simple way to monitor the mental health status.

SRS-22r Self-Image After Surgery for Adolescent Idiopathic Scoliosis at 10-year Follow-up.

STUDY DESIGN: Retrospective cohort. OBJECTIVE: To examine SRS-Self Image scores at up to 10 years after surgery for adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA: Self-image is complex with implications for surgical and patient-reported outcomes after AIS surgery. Surgically modifiable factors that impact self-image are inconsistently reported in the literature with few longer-term reports. We examined the rate and durability of self-image improvement. MATERIALS AND METHODS: An AIS registry was queried for patients with up to 10 years of follow-up after AIS surgery. A mixed effects model estimated change in SRS-22 Self Image from baseline to 6 weeks, 1 year, 2 years, 5 years, and 10 years. All enrolled patients contributed data to the mixed effects models. A sub-analysis of patients with 1-year and 10-year follow-up evaluated worsening/static/improved SRS-22 Self Image scores examined stability of scores over that timeline. Baseline demographic data and 1-year deformity magnitude data were compared between groups using parametric and nonparametric tests as appropriate. RESULTS: Data from 4608 patients contributed data to the longitudinal model; 162 had 1-year and 10-year data. Mean SRS-Self Image improvement at 10-year follow-up was 1.0 (95% CI: 0.9-1.1) point. No significant changes in Self-Image domain scores were estimated from 1-year to 10-year (all P >0.05) postoperative. Forty (25%) patients had SRS-Self Image worsening from 1 year to 10 years, 36 (22%) improved, and 86 (53%) were unchanged. Patients who worsened over 10 years had lower SRS-Self Image at baseline than those unchanged at enrollment (3.3 vs. 3.7, P =0.007). Neither radiographic parameters nor SRS-Mental Health were different at baseline for the enrolled patients. CONCLUSION: Ten years after surgery, 75% of patients reported similar or better SRS-Self Image scores than one year after surgery. Nearly 25% of patients reported worsening self-image at 10 years. Patients who worsened had lower baseline SRS-Self Image scores, without radiographic or mental health differences at baseline or follow-up.

Adolescent idiopathic scoliosis patients treated with bracing, surgery, or observation showed no difference in behavioral and emotional function over a 2-year period.

The purpose of this study was to assess if behavior and emotional function, as measured by the Pearson Behavioral Assessment Survey for Children, Second Edition (BASC-2) in patients and parents, changes with differing treatment protocols in patients with adolescent idiopathic scoliosis (AIS). One previous study showed abnormal BASC-2 scores in a substantial number of patients diagnosed with AIS; however, no study has assessed how these scores change over the course of treatment. AIS patients aged 12 to 21 years completed the BASC-2. The 176-item questionnaire was administered to subjects at enrollment, assessing behavioral and emotional problems across 16 subscales of 5 domains: school problems, internalizing problems, inattention/hyperactivity, emotional symptoms index, and personal adjustment. Parents were given an equivalent assessment survey. Surveys were administered again after 2 years. Subject treatment groups (bracing, surgery, and observation) were established at enrollment. Patients were excluded if they did not complete the BASC-2 at both time points. Forty-six patients met the inclusion criteria, with 13 patients in the surgical, 20 in the bracing, and 13 in the observation treatment groups. At enrollment, 26% (12/46) of subjects with AIS had a clinically significant score in 1 or more subscales, and after 2 years 24% (11/46) of subjects reported a clinically significant score in at least 1 subscale (P = .8). There were no significant differences in scores between enrollment and follow-up in any treatment group. Similar to what was reported in a previous study, only 36% (4/11) of patients had clinically significant scores reported by both patient and parent, conversely 64% (7/11) of parents were unaware of their child's clinically significant behavioral and emotional problems. Common patient-reported subscales for clinically significant and at-risk scores at enrollment included anxiety (24%; 11/46), hyperactivity (24%; 11/46), attention problems (17%; 8/46), and self-esteem (17%; 8/46). At 2-year follow-up, the most commonly reported subscales were anxiety (28%; 13/46), somatization (20%; 9/46), and self-esteem (30%; 14/46). Patients with AIS, whether observed, braced or treated surgically, showed no significant change in behavior and emotional distress over the course of their treatment, or compared with each other at 2-year follow-up.

Comparable satisfaction and clinical outcomes after surgery for adolescent idiopathic scoliosis in the adult (AISA) between the US and Japan.

BACKGROUND: The impact of ethnicity on the surgery outcomes of adolescent idiopathic scoliosis in the adult (AISA) is poorly understood. This study aimed to compare the surgery outcomes for AISA between the United States (US) and Japan (JP). METHODS: 171 surgically treated AISA (20-40y) were consecutively collected from 2 separate multicenter databases. Patients were propensity-score matched for age, gender, curve type, levels fused, and 2y postop spinal alignment. Demographic and radiographic parameters were compared between the US and JP at baseline and 2y post-op. RESULTS: A total of 108 patients were matched by propensity score (age; US vs. JP: 29 ± 6 vs. 29 ± 7y, females: 76 vs. 76%, curve type [Schwab-SRS TypeT; TypeD; TypeL; TypeN]: 35; 35; 30; 0 vs. 37; 33; 30; 0%)] levels fused: 10 ± 4 vs. 10 ± 4, 2y thoracic curve:17 ± 13 vs. 17 ± 12°, 2y CSVL: 10 ± 8 vs. 11 ± 9 mm). Similar clinical improvement was achieved between US and JP (function; 4.2 ± 0.9 vs 4.3 ± 0.6, p = 0.60, pain; 3.8 ± 0.9 vs 4.1 ± 0.8, p = 0.13, satisfaction; 4.3 ± 0.9 vs 4.2 ± 0.7, p = 0.61, total; 4.0 ± 0.8 vs 4.1 ± 0.5, p = 0.60). The correlation analyzes indicated that postoperative SRS-22 subdomains correlated differently with satisfaction (all subdomains moderately correlated with satisfaction in the US while only pain and mental health correlated moderately with satisfaction in JP ([function: r = 0.61 vs 0.29, pain: r = . 72 vs 0.54, self-image: r = 0.72 vs 0.37, mental health: r = 0.64 vs 0.55]). CONCLUSIONS: Surgery for AISA was similarly effective in the US and JP. Satisfaction for spinal surgery among patients in different countries may not be different unless the procedure limits an individual's unique lifestyle that the patient expected to resume.

Why Don't Adolescents Wear Their Brace? A Prospective Study Investigating Psychosocial Characteristics That Predict Scoliosis Brace Wear.

BACKGROUND: Although bracing for adolescent idiopathic scoliosis can prevent curve progression and reduce the risk for future surgery, children frequently do not wear their braces as prescribed. The purpose of this study is to investigate how a broad array of psychosocial characteristics predict future compliance with scoliosis brace wear. METHODS: This was a single institution, prospective cohort study. All adolescents prescribed a first-time brace for adolescent idiopathic scoliosis were eligible. Patients and their parents completed a separate series of questionnaires that assessed baseline psychosocial characteristics across 6 domains: (1) brace-specific attitudes; (2) body image and self-esteem; (3) school performance and social relationships; (4) psychological health; (5) family functioning; and (6) demographics and scoliosis-specific details (242 total questions across 12 validated questionnaires). Objective brace compliance was collected using temperature-sensitive monitors. Defining compliance as percentage of brace prescription completed, comparative analyses were performed to identify baseline psychosocial characteristics that were associated with future wear. A composite measure (Bracing Fidelity Follow-Up Scale [BFFS]) of the 12 most predictive individual questions across all domains (both parent and adolescent) was constructed to help assess which adolescents were at highest risk of failure to wear their brace. Total BFFS score for each parent-adolescent dyad who completed all the included surveys was then determined by awarding one point for each factor that positively influenced future brace wear (maximum 12 points), and a correlation was calculated between total score and percent adherence to prescribed brace wear. RESULTS: A total of 41 patients were included. On average, patients with high self-esteem, above average peer relationships and poor brace-specific attitudes had lower brace compliance, although patients with increased loneliness and parental religiousness had higher compliance. Body image, socioeconomic status, family dynamics, and school performance had no significant relationship with brace use. Total score on the Bracing Fidelity Follow-Up Scale (BFFS) was significantly associated with improved brace wear (r=0.687, P <0.001). Those with a score of 6 or above (n=15/33 [45%], median compliance 96%) were more reliable users (15/15 with compliance >75%), and those with a score of 5 or less (n=18/33 [55%], median compliance 50%) had less consistent brace wear (9/18 with compliance <50%). CONCLUSION: This prospective study identifies numerous baseline psychosocial factors that are associated with future compliance with scoliosis brace wear. Although in need of further validation before widespread clinical application, the novel BFF scale offers a potential opportunity to partially discriminate between compliant and noncompliant scoliosis brace users such that supportive resources (eg, supportive counseling, peer-support groups, additional provider-based education, etc.) can be targeted to those patients most likely to benefit.

Development and Validation of a Health-Related Quality-of-Life Measure in Older Children and Adolescents with Early-Onset Scoliosis: Early-Onset Scoliosis Self-Report Questionnaire (EOSQ-SELF).

BACKGROUND: The 24-question Early-Onset Scoliosis Questionnaire (EOSQ-24) is a proxy measure assessing health-related quality of life (HRQoL) among patients with early-onset scoliosis (EOS). There exists an increasing need to assess HRQoL through a child's own perspective, particularly for older children and adolescents with EOS. The purpose of this study was to develop and validate a self-reported questionnaire, the Early-Onset Scoliosis Self-Report Questionnaire (EOSQ-SELF), to assess HRQoL in older children and adolescents with EOS. METHODS: A literature review, an expert focus group, and patient interviews were used to generate a preliminary survey of appropriate domains and question items. This survey was provided to English-speaking patients with EOS who were 8 to 18 years of age and capable of answering survey questions. Content validity was assessed for clarity and relevance of questions. Confirmatory factors analysis was performed to reduce the number of items and determine domains that fit items. Reliability was evaluated by measuring the internal consistency of items and test-retest reliability. Construct validity was evaluated by convergent, discriminant, and known-group validity. RESULTS: The literature review, expert focus group, and patient interviews identified 59 questions in 14 domains. Psychometric analysis reduced these to 30 questions across 12 domains: General Health, Pain/Discomfort, Pulmonary Function, Transfer, Physical Function/Daily Living, Participation, Fatigue/Energy Level, Sleep, Appearance, Relationships, Emotion, and Satisfaction. The final questionnaire was found to have good content and construct validity and adequate reliability. CONCLUSIONS: The EOSQ-SELF is a valid and reliable instrument for measuring self-reported HRQoL among older children and adolescents with EOS (ages 8 to 18 years). This will serve as an important research outcome measure and enhance clinical care by providing a better understanding of HRQoL for these patients. LEVEL OF EVIDENCE: Diagnostic Level II .

Clinical Outcomes of Corrective Fusion Surgery From the Thoracic Spine to the Pelvis for Adult Spinal Deformity at 1, 2, and 5 years Postoperatively.

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To investigate whether patient-reported outcomes (PROs) were consistent at 2 and 5 years after corrective fusion surgery from the thoracic spine to the pelvis in patients with adult spinal deformity (ASD) and to analyze whether revision surgery affected long-term outcomes. SUMMARY OF BACKGROUND DATA: PROs up to 2 years after corrective surgeries for ASD have been well-studied, but there are few reports of mid- to long-term results. METHODS: We retrospectively analyzed patients with ASD who underwent corrective fusion surgery from the thoracic spine to the pelvis between 2010 and 2015. We investigated radiographic parameters and PROs (Scoliosis Research Society 22r [SRS-22r], Oswestry Disability Index [ODI]) preoperatively and at 1, 2, and 5 years postoperatively, and the correlations between PROs at these time points. We also compared changes in PROs at 5 years in patients who underwent revision surgery and those who did not. RESULTS: A total of 131 patients who underwent corrective fusion surgery from the thoracic spine to the pelvis were analyzed. The PROs at 1 and 5 years after surgery showed significant correlations in all SRS-22r domains (function [r  = 0.620], pain [r  = 0.577], self-image [r  = 0.563], mental health [r  = 0.589], subtotal [r  = 0.663], and ODI [r  = 0.654]). The PROs at 2 and 5 years after surgery showed significantly strong correlations in all domains (function [r  = 0.715], pain [r  = 0.678], self-image [r  = 0.653], mental health [r  = 0.675], subtotal [r  = 0.741], and ODI [r  = 0.746]). There were no significant differences in the change in PROs at 5 years in any domain in patients who underwent revision surgery (all P  > 0.05). CONCLUSION: One-year postoperative PROs improved significantly. Two-year PROs correlated strongly with 5-year postoperative PROs, indicating that 2-year PROs can predict longer term outcomes. The need for revision surgery did not influence the mid- to long-term clinical outcomes of corrective fusion surgery for ASD.Level of Evidence: 3.

Relevant impact of surgery on quality of life for adolescent idiopathic scoliosis : a registry-based two-year follow-up cohort study.

AIMS: To determine the value of scoliosis surgery, it is necessary to evaluate outcomes in domains that matter to patients. Since randomized trials on adolescent idiopathic scoliosis (AIS) are scarce, prospective cohort studies with comparable outcome measures are important. To enhance comparison, a core set of patient-related outcome measures is available. The aim of this study was to evaluate the outcomes of AIS fusion surgery at two-year follow-up using the core outcomes set. METHODS: AIS patients were systematically enrolled in an institutional registry. In all, 144 AIS patients aged ≤ 25 years undergoing primary surgery (median age 15 years (interquartile range 14 to 17) were included. Patient-reported (condition-specific and health-related quality of life (QoL); functional status; back and leg pain intensity) and clinician-reported outcomes (complications, revision surgery) were recorded. Changes in patient-reported outcome measures (PROMs) were analyzed using Friedman's analysis of variance. Clinical relevancy was determined using minimally important changes (Scoliosis Research Society (SRS)-22r), cut-off values for relevant effect on functioning (pain scores) and a patient-acceptable symptom state (PASS; Oswestry Disability Index). RESULTS: At baseline, 65 out of 144 patients (45%) reported numerical rating scale (NRS) back pain scores > 5. All PROMs significantly improved at two-year follow-up. Mean improvements in SRS-22r function (+ 1.2 (SD 0.6)), pain (+ 0.6 (SD 0.8)), and self-image (+ 1.1 (SD 0.7)) domain scores, and the SRS-22r total score (+ 0.5 (SD 0.5)), were clinically relevant. At two-year follow-up, 14 out of 144 patients (10%) reported NRS back pain > 5. Surgical site infections did not occur. Only one patient (0.7%) underwent revision surgery. CONCLUSION: Relevant improvement in functioning, condition-specific and health-related QoL, self-image, and a relevant decrease in pain is shown at two-year follow-up after fusion surgery for AIS, with few adverse events. Contrary to the general perception that AIS is a largely asymptomatic condition, nearly half of patients report significant preoperative back pain, which reduced to 10% at two-year follow-up.

Adolescents' Experiences of Idiopathic Scoliosis in the Presurgical Period: A Qualitative Study.

OBJECTIVE: Adolescent idiopathic scoliosis (AIS) is a sideways curvature of the spine that can progress severely during adolescent development and require surgical intervention. This qualitative study was conducted to explore the psychosocial experiences of adolescents with idiopathic scoliosis during the presurgical stage of treatment. METHODS: Fourteen adolescents with moderate-to-severe AIS aged 12-17 years participated in semistructured interviews and data were analyzed using inductive reflexive thematic analysis. RESULTS: Four key themes were generated from the analysis. "Proceeding with Caution" described adolescents' adaptation to the physical impact of their AIS, while "Am I Different?" encompassed adolescents' perceptions of their changing appearance and visibility of their condition. "An Emotional Journey" captured the rollercoaster of emotions from shock at diagnosis to the daunting realization of the severity of their condition, while knowing others with AIS could ease the emotional burden. Finally, adolescents' concerns and expectations about their prospective surgery were captured by the theme "No Pain, No Gain", whereby they were often keen to put surgery behind them. CONCLUSIONS: Understanding and addressing adolescents' psychosocial support needs as they manage the challenges associated with idiopathic scoliosis is a key component of promoting better outcomes among this patient group. Clinical implications and opportunities for support provision are discussed.

Factors associated with increased back pain in primary thoracic adolescent idiopathic scoliosis 10 years after surgery.

PURPOSE: To identify the prevalence and predictors of nonspecific back pain in primary thoracic adolescent idiopathic scoliosis (AIS) patients at 10 years after surgery. METHODS: This was a case-control multi-center study. A query of patients who underwent surgical correction of major thoracic AIS between 1997 and 2007 with 10-year follow-up was reviewed. SRS-22 pain scores at 10 years were classified as below normal (≤ 2 standard deviations below average for controls of similar age/sex from published literature) or within/above the control range. RESULTS: One hundred and seventy-one patients with an average of 10.5 ± 0.8-years follow-up were included. Average age at surgery was 14 ± 2 years. The rate of pain was 23% for males and 11% for females (p = 0.08). Differences in age, 10-year SRS mental health score, and radiographic measures were noted. Of 12 patients who underwent revision surgery, 42% reported below normal pain scores versus 11% in cases without revision (p = 0.012). Classification and regression tree (CART) analysis identified 10-year thoracic curve magnitude and 10-year mental health scores as significant predictors. Thoracic Cobb of ≤ 26° at 10 years was associated with a 7% rate of below normal pain scores compared to 27.5% when the curve was > 26° (OR = 4.8, p < 0.05). Of those with a curve ≤ 26°, no patients had abnormal pain if the SRS mental health score was > 4.2 and 15% had more pain than normal if mental health score was ≤ 4.2 (OR 23, p < 0.05). CONCLUSION: Increased primary thoracic curve magnitude (> 26°) at 10 years was the primary predictor of increased pain. For patients with less coronal deformity (< 26°), a poor mental health score was associated with an increased rate of pain. Male gender and revision surgery may also play a role in increased pain, however, the overall frequency of these variables were low. LEVEL OF EVIDENCE: Level 3.

Quality of Life Among Patients with Early-Onset Scoliosis Treated with Magnetically Controlled Growing Rods-Early-Term Results.

BACKGROUND: The term "early-onset scoliosis" (EOS) refers to spinal deformities that develop before the age of 10 years. The aim of surgical treatment for EOS is stopping the progression of the curvature, maintaining the correction, ensuring the maximum growth of the vertebrae, and ensuring that the vertebrae remain mobile. Using magnetically controlled growing rods (MCGRs) in the treatment of EOS is intended to protect the patient from the negative effects of repetitive surgeries, increase patient compliance and satisfaction, and increase the speed of return to normal social life. Our aim was to report the early radiological evaluation findings and detect the changes in the quality of life of patients and their parents after the diagnosis of EOS and treatment with MCGRs. METHODS: We performed a retrospective clinical study (level 4 case series) of 20 patients with a surgical indication for the treatment of EOS. The 20 patients had undergone treatment with MCGRs and lengthening procedures at 3-month intervals from August 2014 to August 2016. The mean patient age at surgery was 7.9 years (range, 4-10 years), and the mean length of follow-up was 14.9 months (range, 6-30 months). The preoperative, early postoperative, and final follow-up radiographs of all patients were obtained. The Cobb angle, thoracic kyphosis, spinal height, thoracic height, sagittal balance, coronal balance, shoulder balance, and pelvic balance were measured from the radiographs. All the patients had undergone preoperative and final follow-up respiratory function tests, and all the patients completed the Early Onset Scoliosis 24-item questionnaire (EOSQ-24). The outcome measures were the Cobb angle, thoracic kyphosis, spinal height, thoracic height, sagittal balance, coronal balance, shoulder balance, and pelvic balance. All the patients had undergone preoperative and final follow-up respiratory function tests, and the parents of every patient completed the Turkish version of the EOSQ-24. RESULTS: The preoperative, early postoperative and final follow-up mean Cobb angles were 56.6° (range, 38°-93°), 30.5° (range, 13°-80°), and 33.5° (range, 14°-86°), respectively. These findings showed statistically significant improvement in the Cobb angle (P < 0.05). The thoracic height was also significantly increased. The preoperative, early postoperative, and final follow-up mean height was 181 mm (range, 123-224 mm), 200 mm (range, 164-245 mm), and 212 mm (range, 167-248 mm), respectively (P < 0.05). The measurements for spinal height had also increased significantly, with preoperative, early postoperative, and final follow-up values of 219 mm (range, 213-366 mm), 315 mm (range, 260-402 mm), and 338 mm (range, 261-406 mm), respectively (P < 0.05). The thoracic kyphosis measurement was 41° (range, 5°-65°) preoperatively, which had decreased significantly to 32.5° (range, 0°-53°) at the final follow-up (P < 0.05). Our measurements showed no statistically significant differences in the coronal and sagittal balance, pelvic balance, or shoulder balance. No significant differences were found between the preoperative and postoperative respiratory function test results. The assessment of the EOSQ-24 scores had demonstrated significant improvements in the mean scores at the final follow-up (P < 0.05). When different categories in the EOSQ-24 were evaluated separately, no statistically significant differences were found between the preoperative and final follow-up scores for general health, pain and discomfort, respiratory function, movement capability, physical function, or effects on daily life (P > 0.05). However, the exhaustion and energy levels, emotional state, effect of the disease on the parents and patient, and parent satisfaction scores had increased significantly from the preoperative assessment to the final follow-up (P < 0.05). The financial effect had decreased significantly at the final follow-up compared with the preoperative values (P < 0.05). Four patients had developed complications requiring further treatment, and none of the patients had developed infection that required surgical intervention. CONCLUSIONS: Our study showed that insertion of a MCGR is a safe procedure for treatment of EOS to correct the deformity and improve function in daily life. This method reduces the need for repetitive surgery and the likelihood of complications associated with other treatments. Thus, treatment with MCGRs increases patient satisfaction and facilitates patient compliance.

Development of a Shared Decision-Making Tool for Adolescents With Scoliosis to Decide Between Observation Versus Fusion Surgery.

BACKGROUND: Adolescent patients with moderate to severe idiopathic scoliosis who have completed their skeletal growth face a significant choice in their treatment path: watchful waiting or spinal fusion. Shared decision making (SDM) assists patients and clinicians to find treatments that make intellectual, practical and emotional sense. Our objective was to develop a tool that supports SDM for patients with scoliosis and their families. METHODS: We used a user-centered design approach that included collaboration between patients, surgeons and SDM experts, observation of clinician encounters, and literature review. We focused on adolescent idiopathic scoliosis patients 13 or more years of age with less than 1 year of growth remaining (Risser stage 3 or greater) and curves between 40 and 65 degrees. RESULTS: We included 22 patients, and collected 22 video recordings. From these videos, we identified salient patient priorities for decision making including treatment benefits, surgical complications, pain, scheduling and recovery, and cost. For each theme, we conducted a focused review to obtain the best estimate of effect. Then, an expert SDM designer developed an electronic prototype called Scoliosis Choice. CONCLUSIONS: The initial prototype of the scoliosis SDM was finalized and is currently being field tested in clinic. Scoliosis Choice may help patients and surgeons better understand the potential risks and benefits of spinal fusion vs. observation for scoliosis treatment and improve validated measures of quality in patient-parent-surgeon communication.

Factors Associated with Improved Quality of Life Outcomes in Patients Undergoing Surgery for Adult Spinal Deformity.

STUDY DESIGN: Retrospective longitudinal cohort study. OBJECTIVE: This study aimed to elucidate factors affecting the likelihood of achieving minimum clinically important difference (MCID) to patient-reported outcomes defined by the Scoliosis Research Society-22r (SRS-22r) among patients with adult spinal deformity (ASD) who underwent extensive corrective fusion surgery from the thoracic spine to the pelvis. SUMMARY OF BACKGROUND DATA: Achieving MCID for SRS-22r parameters was a measure of surgical efficacy. Patient characteristics and surgical and radiographic factors that affect the likelihood of achieving MCID for SRS-22r parameters are unknown. METHODS: Data from patients with ASD who underwent extensive corrective fusion surgery from the thoracic spine to the pelvis during 2010 to 2016 were retrospectively reviewed. Data from a total of 167 patients with ≥2 years of follow-up were included. Multivariate analysis was used to investigate factors associated with the likelihood of achieving MCID for each of the SRS-22r domains (Function, Pain, Subtotal) 2 years after surgery. The following MCID values were used: 0.90 for Function, 0.85 for Pain, and 1.05 for the Subtotal. RESULTS: MCID achievement rate was 36.5% for Function, 46.1% for Pain, and 44.3% for the Subtotal domain. In multivariate analysis, preoperative SRS-22r Function (odds ratio [OR] = 0.204, 95% confidence interval [CI] 0.105-0.396) increased the likelihood of achieving MCID for SRS-22r Function. Preoperative SRS-22r Subtotal (OR = 0.211, 95% CI, 0.107-0.413), preoperative pelvic tilt (OR = 1.072, 95% CI, 1.012-1.136), preoperative pelvic incidence minus lumbar lordosis (OR = 0.965, 95% CI, 0.934-0.997), and postoperative sagittal vertical axis (OR = 0.985, 95% CI, 0.974-0.995) affected the likelihood of achieving MCID for the SRS-22r Subtotal. CONCLUSION: Patients with poor preoperative health-related quality of life were more likely to achieve improvement in SRS-22r parameters after extensive corrective fusion surgery for ASD. Achieving postoperative sagittal alignment increased the likelihood of achieving MCID for the SRS-22r Subtotal domain.Level of Evidence: 3.

Effect of Etiology, Radiographic Severity, and Comorbidities on Baseline Parent-Reported Health Measures for Children with Early-Onset Scoliosis.

BACKGROUND: The Classification of Early-Onset Scoliosis (C-EOS) allows providers to differentiate patients, for clinical and research purposes, on the basis of the etiology of their disease as well as radiographic parameters. The Early Onset Scoliosis Questionnaire (EOSQ) is the first disease-specific, parent-reported HRQOL (health-related quality-of-life) outcome measure for this condition. We sought to determine the influence of the C-EOS etiology designation, radiographic parameters, and medical comorbidities on EOSQ scores to differentiate quality of life in this heterogeneous patient population. We hypothesized that baseline EOSQ scores for patients with EOS would be strongly affected by the C-EOS etiology designation. METHODS: The analysis included prospectively enrolled patients with EOSQ scores recorded in a multicenter EOS database prior to intervention for the EOS. EOSQ scores were compared across C-EOS etiologies, severity of disease based on radiographic measurements, and patient comorbidities prior to scoliosis intervention. RESULTS: Six hundred and ten patients with EOS were available for analysis; 119 had congenital, 201 had idiopathic, 156 had neuromuscular, and 134 had syndromic EOS. In multivariate analysis, neuromuscular and syndromic etiologies were associated with lower scores than congenital and idiopathic etiologies in many EOSQ domains including general health, transfer, daily living, fatigue/energy level, and emotion. Patients with neuromuscular EOS had the lowest EOSQ scores in general. Congenital and idiopathic EOS did not differ from each other in any EOSQ domain. Coronal Cobb and kyphosis angles had significant inverse but generally weak correlations with EOSQ domains. Individual medical comorbidities had a minor effect on certain domains while American Society of Anesthesiologists (ASA) class and total number of comorbidities had inverse correlations with most domains. CONCLUSIONS: The underlying etiology of EOS appears to have a significant influence on the parent-reported HRQOL outcomes of the disease. Specifically, syndromic and neuromuscular C-EOS diagnoses are associated with lower EOSQ scores before treatment compared with congenital and idiopathic diagnoses. Radiographic measurements of severity have a relatively small influence on EOSQ scores. These baseline differences in C-EOS-designated etiology should be accounted for in studies comparing outcomes of treatment for this heterogeneous patient population.

Improvement in SRS-22R Self-Image Correlate Most with Patient Satisfaction after 3-Column Osteotomy.

STUDY DESIGN: Longitudinal cohort. OBJECTIVES: The aim of this study was to examine the relationship between patient satisfaction, patient-reported outcome measures (PROMs) and radiographic parameters in adult spine deformity (ASD) patients undergoing three-column osteotomies (3CO). SUMMARY OF BACKGROUND DATA: Identifying factors that influence patient satisfaction in ASD is important. Evidence suggests Scoliosis Research Society-22R (SRS-22R) Self-Image domain correlates with patient satisfaction in patients with ASD. METHODS: This is a retrospective review of ASD patients enrolled in a prospective, multicenter database undergoing a 3CO with complete SRS-22R pre-op and minimum 2-years postop. Spearman correlations were used to evaluate associations between the 2-year SRS Satisfaction score and changes in SRS-22R domain scores, Oswestry Disability Index (ODI), and radiographic parameters. RESULTS: Of 135 patients eligible for 2-year follow-up, 98 patients (73%) had complete pre- and 2-year postop data. The cohort was mostly female (69%) with mean BMI of 29.7 kg/m2 and age of 61.0 years. Mean levels fused was 12.9 with estimated blood loss of 2695 cc and OR time of 407 minutes; 27% were revision surgeries. There was a statistically significant improvement between pre- and 2-year post-op PROMs and all radiographic parameters except Coronal Vertical Axis. The majority of patients had an SRS Satisfaction score of ≥3.0 (90%) or ≥4.0 (68%), consistent with a moderate ceiling effect. Correlations of patient satisfaction was significant for Pain (0.43, P < 0.001), Activity (0.39, P < 0.001), Mental (0.38, P = 0.001) Self-Image (0.52, P < 0.001). ODI and Short-Form-36 Physical component summary had a moderate correlation as well, with mental component summary being weak. There was no statistically significant correlation between any radiographic or operative parameters and patient satisfaction. CONCLUSION: There was statistically significant improvement in all PROMs and radiographic parameters, except coronal vertical axis at 2 years in ASD patients undergoing 3CO. Improvement in SRS Self-Image domain has the strongest correlation with patient satisfaction.Level of Evidence: 3.

Depression Symptoms Are Associated with Poor Functional Status Among Operative Spinal Deformity Patients.

STUDY DESIGN: Retrospective review of prospective multicenter database. OBJECTIVE: The aim of this study was to investigate how preoperative mental status affects preoperative and postoperative disability and health scores in adult spinal deformity (ASD) patients. SUMMARY OF BACKGROUND DATA: The relationship between health-related quality of life (HRQOL) and depression has previously been documented. However, the influence of depression on clinical outcomes among ASD patients is not well understood. METHODS: ASD patients with minimum 2-year follow-up were stratified based on preoperative mental health measured by Short Form 36 (SF-36) mental component score (MCS). Patients with MCS in the 25th and 75th percentile of the cohort were designated as having low and high MCS, respectively. After matching by preoperative demographics and deformity, pre- and post-HRQOL were compared between the two groups. Further analysis was performed to identify individualized questions on the SF-36 that could potentially screen for patients with low MCS. RESULTS: Five hundred thirteen patients were assessed (58.4 years' old, 79% women, mean MCS 45.5). Thresholds for low and high MCS cohorts were 35.0 and 57.3, respectively. After matching by preoperative alignment, low MCS patients had worse Oswestry Disability Index (ODI) (52.3 ±â€Š17.0 vs. 35.7 ±â€Š14.6, P < 0.001) and Scoliosis Research Society-22R scores for all domains (all P < 0.001) compared to high MCS patients. Similar results were maintained at 2-year postop, with low MCS patients having a worse ODI (35.2 ±â€Š20.2 vs. 19.7 ±â€Š18.6, P < 0.001) and MCS (42.4 ±â€Š13.5 vs. 58.6 ±â€Š7.1, P < 0.001). Despite similar preoperative Physical Component Score (PCS), low MCS patients were less likely to reach MCID for PCS (46.1% vs. 70.6%, P < 0.01) and had a lower satisfaction at 2-year follow-up (3.88 ±â€Š1.07 vs. 4.39 ±â€Š0.94, P < 0.001). Questions 5a, 9d, and 9f on the SF-36 were found to be independent predictors of low MCS. CONCLUSION: ASD patients with low MCS are more likely to experience functional limitations before and after surgery and are less likely to be satisfied postoperatively, even when similar clinical goals are achieved. Incorporating psychological factors may assist in decision making.Level of Evidence: 3.

Long-term Patient Perception Following Surgery for Adolescent Idiopathic Scoliosis if Dissatisfied at 2-year Follow-up.

STUDY DESIGN: Longitudinal. OBJECTIVES: To evaluate whether the rate of patients who report low health-related quality of life (HRQOL) scores at 2 years following surgical correction of adolescent idiopathic scoliosis (AIS) improves by 5 years postoperatively. SUMMARY OF BACKGROUND DATA: HRQOL scores are dependent upon a number of factors and even in instances of good surgical correction of a spinal deformity, are not guaranteed to be high postoperatively. Understanding how a low HRQOL score varies over the postoperative period can help surgeons more effectively counsel patients and temper expectations. METHODS: A multicenter database was reviewed for patients with both 2 and 5-year follow-up after spinal fusion and instrumentation for AIS. From a cohort of 916 patients, 52 patients with low HRQOL scores at their 2-year follow-up were identified and reevaluated at 5-year follow-up. A low HRQOL outcome was defined as having SRS-22 domain or total scores less than 2 standard deviations below the mean score. Reoperations were also evaluated to determine if they were associated with HRQOL scores. RESULTS: Of those patients with low SRS-22 HRQOL scores at 2 years postoperatively, improvements were seen in all SRS-22 domains and total scores at the 5-year time point. The greatest change was seen in the satisfaction category where 41 patients showed improvement. The rate of reoperations during this period did not significantly impact patient-reported outcomes. CONCLUSIONS: Having a low HRQOL score 2 years after surgery for AIS does not guarantee a low score 5 years after surgery. Promisingly, most patients demonstrate some improvement in all domains for patient-reported SRS-22 scores at 5-year compared to 2-year follow-up. Understanding the longer term postoperative evolution in patient-reported outcomes may help surgeons to effectively manage and counsel patients who are dissatisfied in the short term.Level of Evidence: 3.
