ABSTRACT
BACKGROUND: Optimal treatment of completely displaced midshaft clavicular fractures in adolescents remains controversial, with some favoring surgical management and others favoring a nonoperative approach. Few studies have comprehensively assessed longer-term nonoperative outcomes. PURPOSE: To prospectively assess patient-reported outcomes (PROs) and radiographic remodeling ≥5 years after injury in teenagers undergoing nonoperative treatment of completely displaced clavicular fractures. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Adolescent patients previously enrolled in a prospective study from a single institution with nonoperatively treated, completely displaced midshaft clavicular fractures ≥5 years from injury were eligible for the study. Patients were clinically evaluated for scapular dyskinesia and strength deficits. Bilateral clavicular imaging assessed residual shortening, displacement, and angulation. PROs included the American Shoulder and Elbow Surgeons (ASES), the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), Marx Shoulder Activity Scale, cosmesis, and return to sports data. RESULTS: A total of 24 patients were available for the follow-up, of whom 17 (71%) consented to additional imaging. The mean cohort age at the time of injury was 14.5 ± 1.1 years, with 88% being male. At a mean follow-up of 6.1 years, all fractures had healed, with no patient requiring secondary interventions. Significant remodeling was observed across all measurements, with improvements of 70% in shortening (22.8 to 6.8 mm; P < .001), 73% in superior displacement (13.4 to 3.6 mm; P < .001), and 83% in angulation (10.4° to 1.8°; P < .001). Thirteen patients (72%) had a >2-cm initial shortening, and all remodeled to <2 cm. PROs were almost universally excellent, with mean ASES, QuickDASH, and Marx activity scores of 99 ± 3, 1 ± 3, and 20 ± 1, respectively, with 79% of patients reporting perfect scores in all 3 domains. Most patients (58%) were completely satisfied with their shoulder appearance, 38% were more satisfied than not, 1 patient (4%) was neither satisfied nor dissatisfied, and no patients were dissatisfied. All patients except 1 who were interested in sports returned to sporting activities. PROs were not associated with bony remodeling (P > .05). CONCLUSION: Teenaged patients with completely displaced clavicular fractures treated nonoperatively can expect excellent radiographic and clinical outcomes 5 years after injury.

BACKGROUND: Up to 25% of youth experience a depressive episode by 18 years of age, leading the US Preventive Services Task Force to recommend depression screening within this population. This study aimed to understand the prevalence of depression identified within pediatric orthopedic clinics compared with primary care clinics after the implementation of a screening program and present data on the prevalence of moderate-severe depression across specific pediatric orthopedic clinics, characterizing and identifying specific populations at higher risk. METHODS: A retrospective review was performed to identify all patients screened using the 2-item and 9-item versions of the Patient Health Questionnaire (PHQ-2/PHQ-9) and the Columbia-Suicide Severity Rating Scale over a 2-year period (October 2018 to January 2021) within pediatric primary care and orthopaedic clinics. Demographic and clinical characteristics were collected. Statistical analysis was performed to compare scores between orthopedic and primary care clinics, as well as between the different pediatric orthopedic subspecialties and included χ 2 test, ANOVA, and logistic regression. RESULTS: There were 32,787 unique adolescent patients screened in primary care clinics, with an additional 14,078 unique adolescent patients screened in orthopaedic clinics, leading to a 30% increase in the overall number of patients receiving depression screening. 5.2% of patients in primary care pediatric clinics screened positive for moderate-severe depression versus 2.0% in pediatric orthopaedic clinics ( P <0.001). 2.7% of primary care patients were at risk of self-harm compared with 0.8% of orthopedic patients ( P <0.001). Within orthopaedic subspecialty clinics, the spine patients were at the highest risk of moderate-severe depression (3.5%), significantly higher than both the sports (1.4%, P =0.006) and patients with acute fracture (1.3%, P <0.001). CONCLUSIONS: This study demonstrates the high incidence of patients screening positive for depression in pediatric and adolescent orthopaedic clinics. By identifying high-risk clinics and patient groups, health care systems can apply a more practical approach and appropriately deploy behavioral health specialists for timely counseling and treatment discussions. LEVEL OF EVIDENCE: Level-III.

PURPOSE: To identify 3D measures of scoliosis from preoperative imaging that are associated with optimal radiographic outcomes after selective thoracic fusion (STF) for adolescent idiopathic scoliosis (AIS). METHODS: Subjects with primary thoracic curves (Lenke 1-4, B or C modifiers) fused selectively (L1 or above) who had preoperative 3D reconstructions and minimum 2 years of follow-up were included. An optimal outcome at 2 years was defined as having 4 of 5 parameters previously defined in the literature: (1) lumbar curve < 26º, (2) deformity flexibility quotient < 4, (3) C7-CSVL < 2 cm, (4) lumbar prominence < 5º and (5) trunk shift < 1.5 cm. Univariate and CART analyses were performed to identify preoperative variables associated with achieving an optimal outcome 2 years postoperatively. RESULTS: Ninety-nine (88F, 11 M) patients met inclusion. Mean age was 15 ± 2 years. Fifty-one subjects (52%) had an optimal outcome. Seven preoperative deformity measures representing smaller thoracolumbar/lumbar deformity in the optimal group were found to be significant on univariate analysis. CART analysis identified the following variables associated with optimal outcomes: difference in apical rotation > 30° = 27% optimal outcomes, difference in apical rotation ≤ 30° and coronal vertebral wedging of lumbar apex > 3° = 46% optimal outcomes, and difference in apical rotation ≤ 30° and coronal vertebral wedging of lumbar apex ≤ 3° = 80% optimal outcomes (p < 0.05). CONCLUSION: Optimal outcomes after STF were associated with a preoperative difference in apical vertebral rotation in the axial plane less than 30° between thoracic and lumbar curves as well as coronal plane vertebral wedging of the lumbar apical vertebra less than 3°.

PURPOSE: The aim of our study was to determine the relationship between Patient Health Questionnaire (PHQ) scores-a simple, validated depression screening tool-and Scoliosis Research Society (SRS)-22 questionnaire scores in patients with idiopathic scoliosis (IS). METHODS: IS patients screened for depression with the PHQ-2 who completed the SRS-22 over a 2-year period were reviewed. If PHQ-2 scores were positive (> 3), the more comprehensive PHQ-9 was administered. Median SRS-22 scores between positive and negative PHQ screens were compared. Nonparametric correlation between PHQ and SRS-22 Mental Health (MH) domain was performed. The ability of the MH domain to discriminate between patients with positive versus negative screens and patients with moderate-severe depression risk versus no-mild risk was evaluated with ROC analysis. RESULTS: 521 patients were included. Patients with + PHQ-2 screens had significantly lower total and individual domain SRS scores, especially within the MH domain (4.0 vs. 3.2). For those with moderate-severe depression risk, total and individual domain scores were also significantly lower (MH domain, 4.0 vs. 3.0, p < 0.05). A weak, but significant correlation was observed between the PHQ and MH domain scores (rho = 0.32, p < 0.001). A cut-off of ≥ 3.6 on the MH domain demonstrated sensitivity of 0.75 and specificity of 0.86 for identifying patients at no-mild risk for depression. CONCLUSION: Recognizing mental health conditions is critical to successful IS treatment as psychosocial conditions can negatively affect treatment outcomes. IS patients scoring < 3.6 on the SRS-22 MH domain should be considered for depression screening due to an increased risk of moderate-severe depression.

STUDY DESIGN: Observational case control. OBJECTIVE: The objective of this study was to evaluate the prevalence of opioid use two years after surgical correction of adolescent idiopathic scoliosis (AIS) and its association with preoperative mental health. SUMMARY OF BACKGROUND DATA: Studies of opiate use have reported that up to 80% of users began their addiction with misuse of prescription opioids. Identifying opioid use and those at risk in the AIS population is critical for optimal outcomes. MATERIALS AND METHODS: A query of a multicenter prospective AIS surgical fusion registry was performed to identify patients of all curve types with responses to question 11 on the Scoliosis Research Society-22 questionnaire at two years postoperative. Question 11 asks about pain medication usage for the patient's back with five specific responses: narcotics daily, narcotics weekly or less, non-narcotics daily, non-narcotics weekly/less, or none. Ordinal regression was used to evaluate the association between preoperative Scoliosis Research Society-22 Mental Health (MH) domain scores and two-year postoperative pain medication usage. RESULTS: A total of 2595 patients who underwent surgery from 2002 to 2019 met inclusion. The average primary curve was 56±12°, average age 14.7±3 years, and 81.5% were female. Forty (1.5%) patients reported utilizing opioids two years after surgery, and a significant difference in preoperative MH scores was observed. Patients taking daily opioids postoperatively had the lowest median preoperative MH score (3.75), followed by non-narcotic group (4), and no medication (4.2, P <0.001). Three patients reporting opioid use postoperatively reported preoperative usage. The rate of two-year postoperative medication use based on the year of surgery demonstrated a small linear decrease in opioid use over time, with a slight increase in nonopioid daily use. CONCLUSIONS: Less than 2% of patients reported taking opioids for back pain two years after surgical correction of AIS. A lower MH score before surgery may place a patient at increased risk for opioid use two years after surgery. An analysis of the year of surgery suggests that changes in prescription practices over time may be occurring. LEVEL OF EVIDENCE: 4.

Background: Glenolabral articular disruption (GLAD) lesions may occur in adolescents with anterior shoulder instability, resulting in articular cartilage loss and reduced functional glenoid surface area. Purpose/Hypothesis: To compare failure rates and patient-reported outcomes (PROs) between adolescents with versus without GLAD lesions who were treated for anterior shoulder instability with arthroscopic stabilization. It was hypothesized that the comparison would yield no significant differences. Study Design: Cohort study; Level of evidence, 3. Methods: Patients aged ≤18 years who were treated for anterior shoulder instability with arthroscopic stabilization between 2010 and 2021 were retrospectively identified. Those patients with a GLAD lesion identified at the time of surgery were compared with patients with >2 years of retrospective follow-up who were matched to the no-GLAD cohort according to pathology and management. Demographic and patient characteristics including recurrent instability, complications, and reoperations were recorded. All patients in the GLAD cohort were contacted to obtain PRO data, including the Single Assessment Numeric Evaluation; the shortened version of the Disabilities of the Arm, Shoulder, and Hand questionnaire; and the Pediatric Adolescent Shoulder Survey. Patients were also asked about recurrent instability and additional shoulder problems. Results: Of 35 included patients (mean age, 15.4 ± 1.6 years; 80% male), 15 patients (43%) with GLAD lesions and 26 patients without GLAD lesions were identified. Both cohorts had similar patient characteristics, number of anchors, and anchor constructs; the mean follow-up period was significantly different (GLAD vs no-GLAD, 6.9 ± 3.3 vs 3.4 ± 1.2 years, respectively; P < .001). Seven of 15 GLAD patients (46.7%) underwent loose body removal; 4 of 15 GLAD patients (26.6%) and 9 of 26 no-GLAD patients (34.6%) had recurrent subjective instability (P = .7). No significant group differences were found in PRO scores, reoperation rates (15% no-GLAD vs 20% GLAD), or percentage of patients with recurrent instability between cohorts (P > .05). Conclusion: Adolescent patients with and without GLAD lesions treated arthroscopically for anterior shoulder instability had similar PROs and failure rates at intermediate duration of follow-up. GLAD lesions may be managed in a similar surgical manner as isolated Bankart tears in teenagers, with expectations of similar outcomes.
ABSTRACT
Background: The pediatric/adolescent shoulder survey (PASS) score is a subjective measure of shoulder symptomology in younger patients. Purpose: To establish the minimal clinically important difference (MCID) and minimal detectable change (MDC) for the PASS score in adolescents after surgical treatment for shoulder instability. Study Design: Case series; Level of evidence, 4. Methods: Included were patients aged 12.5 to 23 years who underwent surgical treatment for shoulder instability and who had completed PASS forms preoperatively and at 3 months postoperatively. The MCID was established using an anchor-based approach, with the Single Assessment Numeric Evaluation (SANE) and shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) as anchors. Change in PASS score between anchor groups was determined using receiver operating characteristic curve analysis. MDC with 90% confidence (MDC90) was also calculated. Range of motion and strength data at 3-month follow-up were evaluated to identify the optimal postoperative PASS score. Factors associated with improvement in PASS score beyond the MDC90 and MCID were determined in a subset of patients with ≥6-month follow-up data. Results: A total of 95 patients were included. The mean PASS score improved significantly from preoperatively to postoperatively (57 ± 15 to 75 ± 16; P < .001). The anchor-based MCID ranged from 12.5 to 13.2 points, with an area under the receiver operating characteristic (AUC) curve of 0.87 for the SANE and 0.99 for the QuickDASH. The MDC90 was 16.5 points. The optimal PASS score at 3 months after surgery was ≥85 (AUC, 0.66). Shorter duration of symptoms, lower preoperative forward elevation, and higher preoperative external rotation were associated with improvement in PASS score above the MDC90 and/or MCID for the subset of patients (n = 25) with ≥6-month follow-up data. Increased number of suture anchors, less preoperative external rotation deficit, and number of previous dislocations had a moderate effect on improvement in outcomes. Conclusion: A postoperative increase in PASS score of ≥16.5 points had a 90% chance of being a true-positive change, while a score change of approximately 13 points was likely clinically relevant. The optimal PASS score after surgery was ≥85. Shorter duration of symptoms, preoperative range of motion, number of surgical anchors, and number of previous dislocations were associated with achieving a clinically relevant improvement in PASS score at minimum 6 months postoperatively.
ABSTRACT
BACKGROUND: Studies have demonstrated that pediatric patients have an increased risk of failure with allograft anterior cruciate ligament reconstruction (ACLR); however, there is no study investigating whether allograft ACLR may be safe in older adolescent patients who are not returning to competitive pivoting sports (ie, low risk). The purpose of this study was to assess outcomes for low-risk older adolescents selected for allograft ACLR. METHODS: We performed a retrospective chart review of patients younger than 18 years who received a bone-patellar-tendon-bone allograft or autograft ACLR by a single orthopaedic surgeon from 2012 to 2020. Patients were offered allograft ACLR if they did not intend to return to pivoting sports for 1 year. The autograft cohort was matched 1:1 based on age, sex, and follow-up. Patients were excluded for skeletal immaturity, multiligamentous injury, prior ipsilateral ACLR, or concomitant realignment procedure. Patients were contacted to obtain patient-reported outcomes at ≥2 years follow-up, including single assessment numerical evaluation, surgery satisfaction, pain scores, Tegner Activity Scale, and the Lysholm Knee Scoring Scale. Parametric and nonparametric tests were used as appropriate. RESULTS: Of the 68 allografts, 40 (59%) met inclusion and 28 (70%) were contacted. Among the 456 autografts, 40 (8.7%) were matched and 26 (65%) were contacted. Two allograft patients (2/40; 5%) failed at a median (interquartile range) follow-up of 36 (12, 60) months. There were 0/40 failures in the autograft cohort and 13/456 (2.9%) among the overall autografts; neither were significantly different from the allograft failure rate (both P > 0.05). Two (5.0%) patients in the autograft cohort required manipulation under anesthesia and arthroscopic lysis of adhesions. There were no significant differences between cohorts for single assessment numerical evaluation, Lysholm, Tegner, pain, and satisfaction scores (all P > 0.05). CONCLUSIONS: Although ACL allograft failure rates remain nearly two times higher than autograft failure rates in older adolescents, our study suggests that careful patient selection can potentially bring this failure rate down to an acceptable level. LEVEL OF EVIDENCE: Level III; retrospective matched cohort study.

BACKGROUND: Acute hematogenous osteomyelitis (AHO) is a relatively common condition in children, and identifying the offending pathogen with blood or tissue cultures aids in diagnosis and medical management while reducing treatment failure. Recent 2021 AHO clinical practice guidelines from the Pediatric Infectious Disease Society recommend obtaining routine tissue cultures, particularly in cases with negative blood cultures. The purpose of this study was to identify variables associated with positive tissue cultures when blood cultures are negative. METHODS: Children with AHO from 18 pediatric medical centers throughout the United States through the Children's ORthopaedic Trauma and Infection Consortium for Evidence-based Study were evaluated for predictors of positive tissue cultures when blood cultures were negative. Cutoffs of predictors were determined with associated sensitivity and specificity. RESULTS: One thousand three children with AHO were included, and in 688/1003 (68.6%) patients, both blood cultures and tissue cultures were obtained. In patients with negative blood cultures (n=385), tissue was positive in 267/385 (69.4%). In multivariate analysis, age ( P <0.001) and C-reactive protein (CRP) ( P =0.004) were independent predictors. With age >3.1 years and CRP >4.1 mg/dL as factors, the sensitivity of obtaining a positive tissue culture when blood cultures were negative was 87.3% (80.9-92.2%) compared with 7.1% (4.4-10.9%) if neither of these factors was present. There was a lower ratio of methicillin-resistant Staphylococcus aureus in blood culture-negative patients who had a positive tissue culture 48/188 (25.5%), compared with patients who had both positive blood and tissue cultures 108/220 (49.1%). CONCLUSION: AHO patients with CRP ≤ 4.1 mg/dL and age under 3.1 years are unlikely to have clinical value from tissue biopsy that exceeds the morbidity associated with this intervention. In patients with CRP > 4.1 mg/dL and age over 3.1 years, obtaining a tissue specimen may add value; however, it is important to note that effective empiric antibiotic coverage may limit the utility of positive tissue cultures in AHO. LEVEL OF EVIDENCE: Level III-Retrospective comparative study.

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.

INTRODUCTION: Forearm fractures are a common pediatric injury. Currently, there is no consensus on treatment for fractures that recur following initial surgical fixation. The objective of this study was to investigate the subsequent fracture rate and patterns and describe the treatment of these forearm fractures. METHODS: We retrospectively identified patients who underwent surgical treatment for an initial forearm fracture at our institution between 2011 and 2019. Patients were included if they sustained a diaphyseal or metadiaphyseal forearm fracture that was initially treated surgically with a plate and screw construct (plate) or elastic stable intramedullary nail (ESIN), and if they subsequently sustained another fracture that was treated at our institution. RESULTS: A total of 349 forearm fractures were treated surgically with ESIN or a plate fixation. Of these, 24 sustained another fracture, yielding a subsequent fracture rate of 10.9% for the plate cohort and 5.1% for the ESIN cohort ( P =0.056). The majority of plate refractures (90%) occurred at the proximal or distal plate edge, while 79% of the fractures treated previously with ESINs occurred at the initial fracture site ( P <0.001). Ninety percent of plate refractures required revision surgery, with 50% underwent plate removal and conversion to ESIN, and 40% underwent revision plating. Within the ESIN cohort, 64% were treated nonsurgically, 21% underwent revision ESINs, and 14% underwent revision plating. Tourniquet time for revision surgeries were shorter for the ESIN cohort (46 vs. 92 min; P =0.012). In both cohorts, all revision surgeries had no complications and healed with evidence of radiographic union. However, 9 patients (37.5%) underwent implant removal (3 plates and 6 ESINs) after subsequent fracture healing. CONCLUSIONS: This is the first study to characterize subsequent forearm fractures following both ESIN and plate fixation and to describe and compare treatment options. Consistent with the literature, refractures following surgical fixation of pediatric forearm fractures may occur at a rate ranging from 5% to 11%. ESINs are both less invasive at the time of initial surgery and can often be treated nonoperatively if there is a subsequent fracture, while plate refractures are more likely to be treated with a second surgery and have a longer average surgery time. LEVEL OF EVIDENCE: Level IV-retrospective case series.

BACKGROUND: Bony remodeling of displaced clavicle fractures in adolescents remains poorly understood. PURPOSE: To evaluate and quantify clavicle remodeling in a large population of adolescents with completely displaced fractures, which were treated nonoperatively, to better understand the factors that may influence this process. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients were identified from the databases of a multicenter study group investigating the functional outcomes of adolescent clavicle fractures. Patients between the ages of 10 and 19 years with completely displaced middiaphyseal clavicle fractures that were treated nonoperatively and who had further radiographic imaging of the affected clavicle at a minimum of 9 months from initial injury were included. Fracture shortening, superior displacement, and angulation were measured on the injury and final follow-up radiographs using previously validated techniques. Furthermore, fracture remodeling was classified as complete/near complete, moderate, or minimal, using an original classification system found to have good to excellent reliability (interobserver reliability = 0.78, intraobserver reliability = 0.90). Classifications were subsequently analyzed quantitatively and qualitatively to determine the factors associated with deformity correction. RESULTS: Ninety-eight patients (mean age, 14.4 ± 2.0 years) were analyzed at a mean radiographic follow-up of 3.4 ± 2.3 years. Fracture shortening, superior displacement, and angulation significantly improved during the follow-up period by 61%, 61%, and 31%, respectively (P < .001). Furthermore, while 41% of the population had initial fracture shortening >20 mm at final follow-up, only 3% of the cohort had residual shortening >20 mm. Fracture remodeling was found to be associated with follow-up time; those with longer follow-up time demonstrated more remodeling (P = .001). Eighty-five percent of patients aged <14 years and 54% of patients aged ≥14 years at time of injury with a minimum follow-up of 4 years underwent complete/near-complete remodeling. CONCLUSION: Significant bony remodeling occurs in adolescent patients with completely displaced clavicle fractures, including older adolescents, and appears to continue over longer time intervals, even beyond the adolescent years. This finding may help explain the low rate of symptomatic malunions in adolescents, even in severely displaced fractures, and particularly when compared with rates reported in adult studies.

PURPOSE: This study compared the outcomes of juvenile patients with cerebral palsy (CP) and scoliosis who underwent spinal fusion (SF) versus growing rod (GR) surgery. METHODS: Two prospective multicenter registries were queried for patients 8-10 years old with minimum 2-year follow-up who underwent SF or GR surgery (no MCGR). Demographics, radiographs, complications, and outcome scores were recorded. RESULTS: There were 35 patients in the SF and 15 in the GR group. The mean age at surgery was 10 and 9.3 years in the SF and GR groups, respectively (p = 0.004). In the SF group preoperatively, the major curve measured 86° and 80° in the GR group (p = 0.40). "Definitive" surgery in the GR group consisted of SF in 10, implant retention in three, and implant removal in two. The SF group had 60.8% and the GR group had 45.0% correction following "definitive" surgery (p = 0.03). In the SF group, 8 patients and in the GR group, 9 patients (SF = 22.9%, GR = 60.0%) had a complication (p = 0.01). In the SF group, two patients (5.7%) had reoperations for infection; eight patients (53.3%) in the GR group had reoperations for infection and implant complications (p < 0.001). In the SF group, 23/30 parents (76.6%) noted that the child's life "improved a lot." In the GR group, 3/6 parents (50.0%) noted they were "neutral" about their child's ability to do things, 2/6 (33.3%) were "very dissatisfied." CONCLUSIONS: SF treatment for juvenile patients with CP and scoliosis resulted in fewer complications and unplanned reoperations and better radiographic outcomes compared with GR. Quality of life improvements were also better in the SF group. LEVEL OF EVIDENCE: Level III.

PURPOSE: As 2-year follow-up may not be sufficient to assess the risk of curve progression following fusion in immature patients with adolescent idiopathic scoliosis (AIS), this study reports on 5-year outcomes of AIS patients, factoring in maturity and surgical approach, to determine whether immature patients are at risk of continued curve progression beyond 2 years. METHODS: A multicenter database was reviewed for AIS patients who underwent spinal fusion with pedicle screw fixation and who had both 2 and 5-year follow-up. Radiographic and SRS-22 scores were compared between three groups: open triradiate cartilage-posterior fusion (OTRC-P), OTRC-combined anterior/posterior fusion (OTRC-APSF), and closed TRC (CTRC, matched to OTRC-P group). RESULTS: 142 subjects were included (67 OTRC-P, 8 OTRC-APSF, 67 CTRC). Main curve type (p = 0.592) and size (p = 0.117) were not different between groups at all timepoints. Compensatory curve size was similar at all timepoints for OTRC-P and CTRC, with a slight increase for OTRC-APSF from immediate postoperative to 5 years. At 5 years, OTRC-P had > 10° loss of correction in 25% of patients, which was greater than in the CTRC (6%) and OTRC-APSF (0%) groups (p = 0.002). No significant differences were found in loss of correction of the compensatory curve or in SRS-22 scores between groups. CONCLUSIONS: Compared to those with CTRC and those treated with anterior/posterior fusion, patients with OTRC treated with posterior fusion had an increased risk of main curve progression greater than 10°, with some continued loss of correction after 2 years. This did not appear to affect patient-reported outcomes.

BACKGROUND: Although current clinical practice guidelines from the American Academy of Orthopaedic Surgeons suggest that Type II and III supracondylar humerus (SCH) fractures be treated by closed reduction and pin fixation, controversy remains as to whether type IIa fractures with no rotation or angular deformity require surgery. The purpose of our study was to prospectively compare radiographic and functional outcomes of type IIa SCH fractures treated with or without surgery. METHODS: Between 2017 and 2019, 105 patients between 2 and 12 years of age presenting with type IIa SCH fractures and without prior elbow trauma, neuromuscular or metabolic conditions, were prospectively enrolled. Ten orthopaedic surgeons managed the patients with 5 preferring surgical treatment and 5 preferring an initial attempt at nonoperative treatment. Patients in the nonoperative cohort were managed with a long-arm cast and close radiographic follow-up. Patients underwent a standardized protocol, including 3 to 4 weeks of casting, bilateral radiographic follow-up 6 months postinjury, and telephone follow-up at 6, 12, and 24 months. RESULTS: Ninety-nine patients met the inclusion criteria (45 nonoperative and 54 operatives). Of the nonoperative patients, 4 (9%) were converted to surgery up to their first clinical follow-up. No differences were identified between the cohorts with respect to demographic data, but patients undergoing surgery had on average 6 degrees more posterior angulation at the fracture site preoperatively (P<0.05). At the final clinical follow-up (mean=6 mo), the nonoperative group had more radiographic extension (176.9 vs 174.4 degrees, P=0.04) as measured by the hourglass angle, but no other clinical or radiographic differences were appreciated. Complications were similar between the nonoperative and operative groups: refracture (4.4 vs 5.6%), avascular necrosis (2.2 vs 1.9%) and infection (0 vs 1.9%) (P>0.05). Patient-reported outcomes at a mean of 24 months showed no differences between groups. CONCLUSION: Contrary to American Academy of Orthopaedic Surgeons guidelines, about 90% of patients with type IIa supracondylar fractures can be treated nonoperatively and will achieve good radiographic and functional outcomes with mild residual deformity improving over time. Patients treated nonoperatively must be monitored closely to assess for early loss of reduction and the need for surgical intervention.

BACKGROUND: Growth modulation through anterior vertebral body tethering (AVBT) has emerged as a fusionless option for the treatment of progressive scoliosis. When tethering the main thoracic curve, the compensatory thoracolumbar/lumbar curve must correct indirectly as a result. The present study evaluated the response of these lumbar curves following AVBT of the main thoracic curves. METHODS: Patients who underwent thoracic AVBT and who had a minimum follow-up of 2 years were included. Magnitudes of the thoracic and lumbar curves were recorded preoperatively and at the first-erect and 2-year postoperative visits. Lumbar curves were further stratified according to their lumbar modifier (A, B, or C). Analysis of variance (ANOVA) and repeated-measures ANOVA were performed to compare correction rates, and the Pearson coefficient was utilized to determine the correlation between the tethered thoracic curve and uninstrumented lumbar curve magnitudes. RESULTS: A total of 218 patients were included. Thoracic curve correction was 40% at the first-erect visit and 43% at 2 years (p = 0.012). Lumbar correction was 30%, 26%, and 18% at the first-erect visit (p < 0.001 for all compared with preoperatively) and minimally changed at 31%, 26%, and 24% at 2 years for lumbar modifiers A, B, and C, respectively. A total of 118 patients (54%) showed thoracic curve improvement between the first-erect and 2-year visits. In a subgroup analysis, these patients had a correction in lumbar curve magnitude from preoperatively to the first-erect visit of 30%, 22%, and 16% for lumbar modifiers A, B, C, respectively, that increased to 42%, 34%, and 31% at 2 years, with strong correlation to thoracic correction at 2-year follow-up (r = 0.557, p < 0.001). CONCLUSIONS: Although there was immediate lumbar correction following AVBT of a main thoracic curve, further improvement following initial correction was only observed among patients with growth modulation of the thoracic curve. Considering all patients, the uninstrumented lumbar curve corrected 30% at 2 years and the instrumented thoracic curve corrected 40%. As indications for AVBT are refined, these data will provide insight into the response of the uninstrumented lumbar curve. LEVEL OF EVIDENCE: Therapeutic Level III .

PURPOSE: To provide a baseline for comparison with future advancements, this study determined the accuracy of preoperative planning of pedicle screw placement using standard radiographs for posterior fusion (PSF) for adolescent idiopathic scoliosis (AIS). METHODS: Ninety-five patients with AIS planned for PSF were prospectively enrolled. Preoperative planning was based upon standard upright posteroanterior and lateral radiographs. The planned number of screws to be placed at each level was recorded. Intraoperatively, all screws were placed by freehand technique. The number of successfully placed screws and the reasons for abandoning screw placement were documented. RESULTS: There were a total of 1783 pedicle screws planned preoperatively. The average planned implant density was 2.0 implants/vertebra. A total of 1723 (96.6%) of the planned screws were placed successfully. Fourteen (0.8%) screws were abandoned after attempted placement (range 0-2 screws/case). Of 241 screws planned in pedicles noted to be "hypoplastic," 13 resulted in the use of a hook or no instrumentation. The placement was not attempted for 49 (range 0-7/case) planned screws due to intraoperative decision-making and a sense that the curve was flexible enough not to require every screw. Three cases (3.2%) required instrumentation of an additional level. CONCLUSIONS: Standard spine radiographs allow for accurate preoperative planning for freehand pedicle screw placement in AIS. Ninety-seven percent of planned screws were placed successfully. The primary reason for deviation from the preoperative plan was intraoperative surgeon decision-making rather than difficulty with screw placement. This study will serve as a baseline when considering the utilization of navigation in PSF for AIS.

PURPOSE: Traditionally, 2-year follow-up data have been the established standard for reporting clinical outcomes following spinal deformity surgery. However, previous studies indicate that 2-year follow-up does not represent long-term outcomes. Currently, there is no clear data that demonstrate a difference in outcomes between the 1 and 2 years postoperative time-periods following posterior spinal fusions (PSF) for adolescent idiopathic scoliosis (AIS). METHODS: A multi-center, prospective database was queried for AIS patients treated with PSF. Clinical outcome scores, assessed by SRS-22, coronal and sagittal radiographic parameters were assessed at time periods: 6 months, 1 year, and 2 years post operatively. Complications and reoperation rates were also assessed. Statistical analysis compared outcomes variables across time-points to assess for significant differences. RESULTS: 694 patients (82.6% female, mean age at surgery 14.9 ± 2.13 years) were identified. Between post-operative year 1 and 2, significant difference in SRS-22 domain scores were present for function domain (4.5 vs. 4.6; p < 0.001), mental health domain (4.3 vs. 4.2; p < 0.001), and total domain score (4.4 vs. 4.4; p = 0.03) but were below the minimal clinically important difference threshold. New complication development was significantly higher within the first year following surgery than the 1-2 year follow-up period (p < 0.001) with greater complication severity within the 0-1 year follow-up period (P = 0.03). CONCLUSION: There are no clinically important changes in SRS-22 domain scores between 1 and 2 years following PSF for AIS, with higher complications in the first year following PSF. Two-year follow-up data provide little added clinical information while under-estimating the cumulative complication and reoperation rates at long-term follow-up.

BACKGROUND: Understanding differences between types of study design (SD) and level of evidence (LOE) are important when selecting research for presentation or publication and determining its potential clinical impact. The purpose of this study was to evaluate interobserver and intraobserver reliability when assigning LOE and SD as well as quantify the impact of a commonly used reference aid on these assessments. METHODS: Thirty-six accepted abstracts from the Pediatric Orthopaedic Society of North America (POSNA) 2021 annual meeting were selected for this study. Thirteen reviewers from the POSNA Evidence-Based Practice Committee were asked to determine LOE and SD for each abstract, first without any assistance or resources. Four weeks later, abstracts were reviewed again with the guidance of the Journal of Bone and Joint Surgery (JBJS) LOE chart, which is adapted from the Oxford Centre for Evidence-Based Medicine. Interobserver and intraobserver reliability were calculated using Fleiss' kappa statistic (k). χ2 analysis was used to compare the rate of SD-LOE mismatch between the first and second round of reviews. RESULTS: Interobserver reliability for LOE improved slightly from fair (k=0.28) to moderate (k=0.43) with use of the JBJS chart. There was better agreement with increasing LOE, with the most frequent disagreement between levels 3 and 4. Interobserver reliability for SD was fair for both rounds 1 (k=0.29) and 2 (k=0.37). Similar to LOE, there was better agreement with stronger SD. Intraobserver reliability was widely variable for both LOE and SD (k=0.10 to 0.92 for both). When matching a selected SD to its associated LOE, the overall rate of correct concordance was 82% in round 1 and 92% in round 2 (P<0.001). CONCLUSION: Interobserver reliability for LOE and SD was fair to moderate at best, even among experienced reviewers. Use of the JBJS/Oxford chart mildly improved agreement on LOE and resulted in less SD-LOE mismatch, but did not affect agreement on SD. LEVEL OF EVIDENCE: Level II.

INTRODUCTION: Patients with surgically treated Lenke 5 curves require at least partial fusion of the lumbar spine. The implications of lumbar fusion remain unknown as long-term follow-up is sparse. METHODS: A retrospective review of a prospectively collected registry of patients with Lenke 5 curves treated with spinal fusion was performed. Clinical and radiographic outcomes as well as SRS-22 scores were collected at 2- and 10-year follow-up. RESULTS: 54 of 247 available patients met all inclusion criteria [26 treated with posterior spinal fusion (PSF) and 28 with anterior spinal fusion (ASF)]. Preoperative lumbar curve magnitude was 45.1 ± 8.4° and corrected to 14.0 ± 7.2° (p < 0.001). A 3.3 ± 7.3° increase in curve size was noted at final follow-up (p < 0.008) with 20.3% of patients having a loss of correction (LOC)of 10° or more. Thoracic curve correction and kyphosis were stable at 10-year follow-up. End vertebrae angulation improved from 11.2 ± 23.2° to 0.96 ± 6.4° (p = 0.004) and translation improved from 2.5 ± 2.9 to 0.92 ± 1.5 cm (p = 0.008) with no LOC. Disc wedging below the lower instrumented vertebrae increased from 0.3 ± 4.9° to 2.8 ± 4.4° (p < 0.001) with no change at 10 years. SRS-22 self-image and satisfaction improved from post-operative to final follow-up. No patient required a second operation. CONCLUSIONS: Both ASF and PSF showed durable results at 10-year follow-up with no obvious difference between approaches. 20% of patients had a LOC > 10°; this did not correlate with pain or need for revision surgery. Disc wedging was stable. Selection of LIV did not correlate with pain scores. LEVEL OF EVIDENCE: Level III.
