Operative Treatment of Cervical Spine Injuries Sustained in Youth Sports.

BACKGROUND: Little data exists on surgical outcomes of sports-related cervical spine injuries (CSI) sustained in children and adolescent athletes. This study reviewed demographics, injury characteristics, management, and operative outcomes of severe CSI encountered in youth sports. METHODS: Children below 18 years with operative sports-related CSI at a Level 1 pediatric trauma center were reviewed (2004 to 2019). All patients underwent morden cervical spine instrumentation and fusion. Clinical, radiographic, and surgical characteristics were analyzed. RESULTS: A total of 3231 patients (mean, 11.3±4.6 y) with neck pain were evaluated for CSI. Sports/recreational activities were the most common etiology in 1358 cases (42.0%). Twenty-nine patients (2.1%) with sports-related CSI (mean age, 14.5 y; range, 6.4 to 17.8 y) required surgical intervention. Twenty-five were males (86%). Operative CSI occurred in football (n=8), wrestling (n=7), gymnastics (n=5), diving (n=4), trampoline (n=2), hockey (n=1), snowboarding (n=1), and biking (n=1). Mechanisms were 27 hyperflexion/axial loading (93%) and 2 hyperextension injuries (7%). Most were cervical fractures (79%) and subaxial injuries (79%). Seven patients (24%) sustained spinal cord injury (SCI) and 3 patients (10%) cord contusion or myelomalacia without neurological deficits. The risk of SCI increased with age (P=0.03). Postoperatively, 2 SCI patients (29%) improved 1 American Spinal Injury Association Impairment Scale Grade and 1 (14%) improved 2 American Spinal Injury Association Impairment Scale Grades. Increased complications developed in SCI than non-SCI cases (mean, 2.0 vs. 0.1 complications; P=0.02). Bony fusion occurred in 26/28 patients (93%) after a median of 7.2 months (interquartile range, 6 to 15 mo). Ten patients (34%) returned to their baseline sport and 9 (31%) to lower-level activities. CONCLUSIONS: The incidence of sports-related CSI requiring surgery is low with differences in age/sex, sport, and injury patterns. Older males with hyperflexion/axial loading injuries in contact sports were at greatest risk of SCI, complications, and permanent disability. Prevention campaigns, education on proper tackling techniques, and neck strength training are required in sports at high risk of hyperflexion/axial loading injury. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

Management of Gustilo-Anderson Type II and IIIA Open Long Bone Fractures in Children: Which Wounds Require a Second Washout?

INTRODUCTION: Timing of wound closure in pediatric Gustilo-Anderson grade II and IIIA open long bone fracture remain controversial. Our aims are (1) to determine the proportion of patients with these fractures whose wounds can be treated with early primary wound closure (EPWC); (2) to compare the complication rates between EPWC and delayed wound closure (DWC); and (3) to determine factors associated with higher likelihood of undergoing DWC. PATIENTS AND METHODS: At a level-1 pediatric trauma center, 96 patients (younger than 18 y) who sustained Gustilo-Anderson grade II and IIIA open long bone fractures (humerus, radius, ulnar, femur, or tibia) within a 10-year period (2006-2016) were included for this study. Decision for EPWC versus DWC was at the discretion of the attending surgeon at time of initial surgery. Data collection was via retrospective review of charts and radiographs. Particular attention was paid to the incidence of return to operating room rate, nonunion, compartment syndrome, and infection. Median follow-up duration was 7.5 months (interquartile range: 3.6 to 25.3 mo). All patients were followed-up at least until bony union. RESULTS: Overall, 81% of patients (78/96) underwent EPWC. Of the grade II fractures, 86% underwent EPWC. Four patients (5%) in the EPWC group and 1 patient (6%) in the DWC group had at least 1 complication. When controlling for mechanism of injury, Gustilo-Anderson fracture type and age, there was no difference in rate of complications between the EPWC and the DWC groups. Grade IIIA fractures and being involved in a motor vehicle accident were factors associated with a higher likelihood of undergoing DWC. CONCLUSION: The majority of grade II and IIIA pediatric long bone fractures may be safely treatable with EPWC without additional washouts. Future prospective research is required to further define the subgroups that can benefit from DWC. LEVEL OF EVIDENCE: Level IV-therapeutic, case cohort study.

Fracture Table Application for Pediatric Femur Fractures: Incidence and Risk Factors Associated With Adverse Outcomes.

BACKGROUND: Flexible elastic nails, submuscular plating, and rigid locked intramedullary nails are common methods of fixation for pediatric femur fractures (PFF) in which the fracture table is used to aid reduction. Little is known about complications associated with fracture table application in PFF. The purpose of this study was to determine the incidence and risk factors associated with adverse outcomes related to fracture table application for the treatment of PFF. METHODS: A retrospective chart review of all children (younger than 18 y) treated for a femur fracture with the use of the fracture table between 2004 and 2015 at a single tertiary pediatric hospital was performed. Data on demographics, mechanism of injury, treatment modality, radiographic characteristics, and fracture table-related complications were gathered. Complications of interest included nerve palsy, skin breakdown/ulceration, vascular injury, and compartment syndrome. Penalized likelihood logistic regression was used to determine risk factors associated with adverse outcomes. RESULTS: In total, 260 patients were included. There were 8 patients with nerve palsies related to positioning and traction on the fracture table (1 bilateral and 6 ipsilateral peroneal nerve palsies, 1 contralateral tibial nerve palsy; incidence of 3.1%). No other fracture table-related complications were recorded. Patients who developed a nerve palsy were significantly heavier (78.7 vs. 44.3 kg, P<0.001) and had a significantly longer mean surgical time (188.6 vs. 117.0 min, P<0.001). Multivariate analysis demonstrated weight to be the only significant risk factor for complications, with a 5% increase in odds of complication with each additional kilogram (odds ratio, 1.05; confidence interval, 1.03-1.08; P<0.001). CONCLUSIONS: Nerve palsy related to the use of the fracture table during the fixation of PFF occurred in 3.1% of patients in our series. Patients who developed nerve palsies were significantly heavier and had significantly longer surgical times. Although the use of the fracture table for fixation of PFF is safe, every effort should be made to minimize time in traction to avoid iatrogenic nerve palsy, particularly in heavier children (>80 kg). LEVEL OF EVIDENCE: Level III.

Defining the volume of consultations for musculoskeletal infection encountered by pediatric orthopaedic services in the United States.

OBJECTIVE: Adequate resources are required to rapidly diagnose and treat pediatric musculoskeletal infection (MSKI). The workload MSKI consults contribute to pediatric orthopaedic services is unknown as prior epidemiologic studies are variable and negative work-ups are not included in national discharge databases. The hypothesis was tested that MSKI consults constitute a substantial volume of total consultations for pediatric orthopaedic services across the United States. STUDY DESIGN: Eighteen institutions from the Children's ORthopaedic Trauma and Infection Consortium for Evidence-based Study (CORTICES) group retrospectively reviewed a minimum of 1 year of hospital data, reporting the total number of surgeons, total consultations, and MSKI-related consultations. Consultations were classified by the location of consultation (emergency department or inpatient). Culture positivity rate and pathogens were also reported. RESULTS: 87,449 total orthopaedic consultations and 7,814 MSKI-related consultations performed by 229 pediatric orthopaedic surgeons were reviewed. There was an average of 13 orthopaedic surgeons per site each performing an average of 154 consultations per year. On average, 9% of consultations were MSKI related and 37% of these consults yielded positive cultures. Finally, a weak inverse monotonic relationship was noted between percent culture positivity and percent of total orthopedic consults for MSKI. CONCLUSION: At large, academic pediatric tertiary care centers, pediatric orthopaedic services consult on an average of ~3,000 'rule-out' MSKI cases annually. These patients account for nearly 1 in 10 orthopaedic consultations, of which 1 in 3 are culture positive. Considering that 2 in 3 consultations were culture negative, estimating resources required for pediatric orthopaedic consult services to work up and treat children based on culture positive administrative discharge data underestimates clinical need. Finally, ascertainment bias must be considered when comparing differences in culture rates from different institution's pediatric orthopaedics services, given the variability in when orthopaedic physicians become involved in a MSKI workup.

The AOSpine thoracolumbar spine injury classification system: A comparative study with the thoracolumbar injury classification system and severity score in children.

BACKGROUND: There is no uniform classification in the pediatric population for thoracolumbar (TL) fractures, nor any operative guidelines. This study evaluates the AOSpine TL spine injury classification in the pediatric population and compares it to the thoracolumbar injury classification system (TLICS), which has previously been validated in pediatric spine trauma. METHODS: Twenty-eight patients with operative TL injuries were identified from 2006 to 2016. Inclusion criteria included available imaging, operative records, age <18, and posterior approach. Each case was classified by AOSpine TL spine injury classification and TLICS. Each classification was compared to documented intraoperative posterior ligamentous complex (PLC) integrity as well as each other. RESULTS: Utilizing the AOSpine TL spine injury classification, 7 patients had type A injuries, 15 patients had type B injuries, and 6 patients had type C injuries; 21 patients had injuries classified as involving the PLC. Using TLICS, 16 patients had burst fractures, 6 patients had distraction injuries, and 6 patients had translation injuries; 21 patients had injuries classified as involving the PLC. Spearman correlation analysis substantiated convergence of AOSpine TL spine injury classification scores to TLICS scores (r = 0.75; 95% confidence interval, CI = 0.51 to 0.98; P < .001). Concordance between PLC integrity by each classification and intraoperative evaluation was 96% (27/28) of cases (k = 0.91; 95% CI = 0.73 to 1.08). Neurologic status was 100% concordant between the AOSpine TL spine injury classification and TLICS. CONCLUSION: There is high statistical correlation between the AOSpine TL spine injury classification and TLICS, and to intraoperative evaluation of the PLC, suggesting that the AOSpine TL spine injury classification is applicable to the pediatric population.
