RESUMEN
STUDY DESIGN: A retrospective comparative study. OBJECTIVE: The aim of this study was to compare the length and diameter of thoracic pedicles in patients with adolescent idiopathic scoliosis (AIS) as measured on preoperative magnetic resonance imaging (pMRI) to intraoperative computed tomography (iCT) scan. SUMMARY OF BACKGROUND DATA: Optimally sized pedicle screw placement during instrumented posterior spinal fusion for AIS can maximize correction and minimize screw pullout. While iCT-guided navigation can quickly estimate screw position and size, this technology is not universally available. Many surgeons utilize pMRI, when obtained, to estimate screw sizes. Data comparing these measurements on pMRI and iCT is limited. We hypothesized that in patients with surgical magnitude AIS, pedicle length, and diameter measured on pMRI would have at least moderate reliability compared to those made on iCT images. MATERIALS AND METHODS: The pMRI and iCT for 60 patients with structural thoracic curves who underwent posterior spinal fusion for AIS at a single center between 2009 and 2017 were analyzed. Bilateral T5-T12 vertebral levels were evaluated for pedicle chord length and pedicle isthmic diameter on both pMRI and iCT. Between-study reliability and interrater reliability was evaluated for each level of the thoracic spine. RESULTS: There is good reliability for pedicle length [intraclass correlation coefficient (ICC)=0.8, 95% confidence interval (CI): 0.78-0.83] and diameter (ICC=0.86, 95% CI: 0.84-0.88) between pMRI and iCT. When assessed by level, T6 has the lowest reliability for length (ICC=0.52, 95% CI: 0.33-0.67) and diameter (ICC=0.55, 95% CI: 0.35-0.69). Interrater reliability ranged from moderate-to-good reliability for all pedicle measurements for both length and diameter on pMRI and iCT. CONCLUSION: Pedicle measurements made on pMRI may be used with reasonable reliability to predict pedicle dimensions visualized on iCT, allowing surgeons to preoperatively plan pedicle screw sizes based off magnetic resonance imaging.

BACKGROUND: Supracondylar humerus fractures are the most commonly operated upper extremity fracture in pediatric orthopaedics, yet there does not currently exist a standardized recommendation for a postoperative protocol. As advanced practice providers take on larger roles in the care of fracture patients, it may alleviate confusion to standardize postoperative protocols. The aim of this study was to compare outcomes between three different postoperative management protocols following operative fixation of supracondylar humerus fractures. METHODS: This is a retrospective study of all patients who underwent operative fixation of a supracondylar humerus fracture during the 2014 to 2015 academic year. Postoperative protocols were classified as either "liberal," "intermediate," or "conservative," based on how quickly the surgeon allowed unrestricted motion of the elbow postoperatively. Patients were evaluated for range of motion, functional elbow motion, and elbow clinical function, as well for postoperative complications. Univariate analysis was conducted to detect the differences in outcomes between protocol groups with P<0.01 considered significant. RESULTS: One hundred patients were included in the final analysis, with 17 patients in the liberal group, 50 in the intermediate group, and 33 in the conservative group. There were no differences in patient population (age, sex, fracture type, concomitant nerve palsy, ipsilateral injuries, or physical therapy referrals) between the groups (P>0.01). There were no differences in range of motion, functional motion, or elbow clinical function (P>0.01) between the postoperative protocol groups. There were no postoperative complications (unplanned return to operating room, refracture, need for fixation revision, or infection) in any patient. CONCLUSIONS: There were no differences in postoperative complications or outcomes between the patients in the liberal, intermediate, or conservative protocol groups. In an efficiency-focused era, we conclude that a standardized liberal protocol be considered at a busy orthopaedic center. LEVEL OF EVIDENCE: This study is a level III therapeutic study. It is a retrospective study that compares the outcomes after following 1 of 3 different postoperative protocols.

BACKGROUND: Hand radiographs for skeletal maturity staging are now frequently used to evaluate remaining growth potential for patients with adolescent idiopathic scoliosis (AIS). Our objective was to create a model predicting a patient's risk of curve progression based on modern treatment standards. METHODS: We retrospectively reviewed all AIS patients presenting with a major curve <50 degrees, available hand radiographs, and complete follow up through skeletal maturity at our institution over a 3-year period. Patients with growth remaining underwent rigid bracing of curves >25 degrees, whereas patients between 10 and 25 degrees were observed. Treatment success was defined as reaching skeletal maturity with a major curve <50 degrees. Four risk categories were identified based on likelihood of curve progression. RESULTS: Of 609 AIS patients (75.4% female) presenting with curves over 10 degrees and reaching skeletal maturity at most recent follow up, 503 (82.6%) had major thoracic curves. 16.3% (82/503) of thoracic curves progressed into surgical treatment range. The highest risk group (Sanders 1 to 6 and curve 40 to 49 degrees, Sanders 1 to 2 and curve 30 to 39) demonstrate a 30% success rate with nonoperative treatment. This constitutes an 111.1 times (95% confidence interval: 47.6 to 250.0, P<0.001) higher risk of progression to surgical range than patients in the lowest risk categories (Sanders 1 to 8 and curve 10 to 19 degrees, Sanders 3 to 8 and curve 20 to 29 degrees, Sanders 5 to 8 and curve 30 to 39 degrees). CONCLUSIONS: Skeletal maturity and curve magnitude have strong predictive value for future curve progression. The results presented here represent a valuable resource for orthopaedic providers regarding a patient's risk of progression and ultimate surgical risk. LEVEL OF EVIDENCE: Level III-retrospective cohort study.

BACKGROUND: Patients with adolescent idiopathic scoliosis (AIS) are commonly monitored for curve progression with spinal radiographs; however, the utility of magnetic resonance imaging (MRI) screening is unclear. The purpose of this study was to assess the findings of screening MRI for patients with a nonsurgical curve size ordered during routine clinical care and compare them with MRI ordered for patients with large curves as part of preoperative screening. METHODS: All consecutive patients with presumed AIS who underwent entire-spine MRI with a presumed diagnosis of idiopathic scoliosis at a single institution between 2017 and 2019 were retrospectively reviewed. Patients were stratified based on MRI indication into the following groups: preoperative evaluation, pain, neurological symptoms, abnormal radiographic curve appearance, rapidly progressive curve, and other. Neural axis abnormalities recorded included concern for tethered spinal cord, syringomyelia, and Chiari malformation. The MRI findings of preoperative patients with large curves were compared with all other patients. The number needed to diagnose (NND) a neurological finding was calculated in patients whose MRIs were ordered during routine clinical care. The amount charged for each patient undergoing entire-spine MRI was determined by review of our institution's Financial Decision Support system. RESULTS: There were 344 patients included in this study with 214 (62%) MRIs performed for preoperative evaluation. Although MRI abnormalities were found in 49% of patients, only 7.0% (24/344) demonstrated neural axis abnormalities with no difference between preoperative and other indications (P=0.37). For patients with nonsurgical curves undergoing MRI due to a complaint of back pain (n=28), there were no neural axis abnormalities, and a lower rate of disk herniation/degenerative changes detected compared with preoperative MRI (3.6% vs. 18%, P=0.06). Among the 15 patients undergoing MRI for a neurological concern, 1 had a neural axis abnormality that required surgical detethering. The NND for MRI to detect a neural axis abnormality that potentially required neurosurgical intervention in nonpreoperative patients with a neurological concern was 34.4. The average cost for MRI was $17,816 (range: $2601 to $22,411) with a total cost of $2,368,439 for nonsurgical curves. CONCLUSIONS: Entire-spine MRI for nonpreoperative indications including pain, abnormal radiographic curve appearance, and rapid curve progression has minimal utility for patients with AIS. For patients with neurological complaints, the NND a potentially treatment-altering finding with MRI is 34.4. LEVEL OF EVIDENCE: Level II-diagnostic.

BACKGROUND: Patients with cerebral palsy scoliosis (CPS) experience higher complication rates compared with idiopathic scoliosis and often present for surgery with larger curves. Prediction of an inflection point for rapid deformity progression has proven difficult. A proximal humerus-based skeletal maturity staging system (HS) has been recently validated and is commonly visible on the posteroanterior radiograph. The authors hypothesize that this system can be used to identify a period at which CPS may progress rapidly, perhaps facilitating discussion of timely surgical intervention. METHODS: A retrospective review was conducted for nonambulatory pediatric patients with CPS who presented between 2009 and 2018 at our institution. All patients were considered for inclusion regardless of operative or nonoperative management. Patients who were skeletally mature at initial evaluation or had prior spine surgery were excluded. The authors analyzed radiographs in each HS available. Survival was calculated for cutoffs of 60 and 70 degrees (numbers found to increase intraoperative and postoperative complications for CPS). RESULTS: Eighty-six patients with CPS were identified (54 male individuals). Major curves increased significantly between HS 1 and 2 (27.7 to 46.6 degrees, P=0.009) and HS 3 and 4 (53.1 to 67.9 degrees, P=0.023). The proportion of curves ≥70 degrees were significantly different between HS (P<0.001), with the greatest increase between HS 3 and 4 (24% to 51%; ≥70 degrees). The largest drop in the 60/70-degree survival curves was between HS 3 and 4. In a subanalysis, 69% of patients with curves ≥40 degrees but <70 degrees in stage 3 would progress ≥70 degrees by stage 4. CONCLUSIONS: Identifying a period of rapid curve progression may guide surgical planning before CPS curves become large, stiff, and more difficult to fix. Our findings suggest that humeral skeletal maturity staging is a valuable decision-making tool in neuromuscular scoliosis, with the HS 3 to 4 transition representing the time of the greatest risk of progression. Consider a surgical discussion or shortened follow-up interval for patients with CPS with curves ≥40 degrees who are HS 3. LEVEL OF EVIDENCE: Level II.

BACKGROUND: Femoral shaft fractures are a common cause for hospital admission and surgery in pediatric patients, and laboratory studies are often ordered for historical concerns of excessive bleeding. Recent literature has challenged these assumptions, and unnecessary testing causes undue pain and costs in children. No previous studies have offered evidence-based recommendations for perioperative laboratories in isolated pediatric femoral shaft fractures. METHODS: We retrospectively reviewed all patients presenting with femoral shaft fractures at our pediatric trauma center between 2013 and 2017. Patients with multitrauma injuries, metabolic/neuromuscular diseases, or intensive care unit stays were excluded. Necessity of laboratory tests was determined by rates of anemia, blood transfusions, specialist consultations, and delayed surgeries. Ordering patterns were recorded, with cost estimation based on Healthcare Bluebook. RESULTS: We reviewed 95 patients (mean age, 7.9±4.8 y; 70 males). Treatments included elastic nails (33/95, 34.7%), reamed intramedullary nails (24/95, 25.3%), plates/screws (12/95, 12.6%), and spica casting (26/95, 27.4%). Of 32 patients with preoperative coagulation laboratories, 11 were abnormal; however none resulted in hematology consultations or procedure delays. Seventy-five patients (78.9%) and 15 patients (15.8%) had complete blood counts preoperatively and postoperative day 1, respectively. Four patients (4.2%) had hemoglobin<8 g/dL postoperatively, however, there were no perioperative blood transfusions. Of these 4, 3 underwent either reamed intramedullary nails or open reduction internal fixation with plates/screws. Twenty-six patients (27.4%) had preoperative basic metabolic panels that did not alter medical care. On the basis of our criteria, over 72% of laboratories appeared unnecessary, with a total potential cost of $8567. Over 80% of orders were from the emergency department by residents or attending physicians. CONCLUSIONS: Perioperative laboratory orders may be unnecessary in most isolated pediatric femoral shaft fractures, subjecting patients to extraneous costs, and associated pain. However, laboratories may be justified based on clinical circumstances or for older patients treated with reamed nails or plates/screws. Evidence-based recommendations for perioperative laboratory orders offer the potential to improve quality and value and minimize harm in pediatric orthopaedic trauma. LEVEL OF EVIDENCE: Level III-retrospective comparative study (therapeutic).

BACKGROUND: The management of septic arthritis of the hip in children can be complicated by the presence of additional coexisting periarticular infections (PAIs). Criteria predicting the presence of PAI have recently been proposed by Rosenfeld and colleagues with the goal of using magnetic resonance imaging (MRI) efficiently in the workup of septic arthritis. The purpose of this study was to determine the applicability of recently published predictive criteria for PAI (developed in the Southwestern United States using a variety of joints) to septic arthritis of the hip treated at a large Northeastern tertiary care center. METHODS: We studied patients treated for septic arthritis of the hip with irrigation and debridement in a large Northeastern tertiary care center over a 10-year period. Laboratory and clinical variables related to presentation, treatment, and outcome were collected. Subjects with and without a perioperative MRI were compared with published criteria by Rosenfeld and colleagues. RESULTS: Fifty-one subjects (53 hips) were identified with a mean age of 7.0 years (range, 1.2 to 19.3 y) and mean follow-up was 16 months (range, 2 to 85 mo). MRIs were obtained in 20 subjects (43%). Coexisting osteomyelitis was revealed in 7/20 of these studies (35% of MRIs); 4 of which showed coexisting intramuscular abscesses. Within our MRI cohort, the Rosenfeld criteria were found to have a sensitivity of 86%, a specificity of 54%, and a false-positive rate of 50% for the hip (compared with originally reported sensitivity of 90%, specificity of 67%, and false-positive rate of 33%). Overall, advanced imaging changed management in 5/51 patients (9%) by influencing the need for further treatment, whereas the remainder underwent isolated treatment of the septic hip joint with no adverse outcomes. One patient in the MRI cohort (without PAI) developed osteonecrosis of the femoral head. CONCLUSIONS: We found lower sensitivity and specificity and higher false-positive rates for the Rosenfeld criteria in the hip for our geographically distinct population. Using the Rosenfeld criteria, MRIs would have been ordered unnecessarily in half of our series. Because of potential differences in regional microbiology and anatomic-specific factors, general predictive criteria for coexisting PAI based a single geographic region may be less generalizable to cases of hip sepsis in other geographic areas such as the Northeastern United States. LEVEL OF EVIDENCE: Level 4-retrospective cohort study.

Pediatric distal humerus fractures are common, and numerous variations can occur depending on patient's age, position of the extremity at the time of injury, and energy of impact. Classic injury patterns include the flexion/extension supracondylar humerus, medial epicondyle, lateral condyle, and the transphyseal distal humerus. We describe our treatment philosophy for pediatric elbow fractures and how these principles were applied to some unusual fractures that presented to our institution.

BACKGROUND: Although many studies have separately investigated the treatment of developmental dysplasia of the hip and spastic hip disease, little data exist regarding the treatment of infants with dislocated hips and underlying spasticity. The purpose of this study was to review our results after the surgical treatment of these infants. METHODS: We retrospectively reviewed all children below 3 years of age who underwent hip reconstruction for dislocated hips in the setting of cerebral palsy or other spastic/high-tone neuromuscular disease. Medical records were reviewed for clinical data including treatment course, complications, and need for further surgery. Preoperative and postoperative radiographs were used to determine International Hip Dysplasia Institute (IHDI) grade of dislocation, acetabular index, migration percentage, and presence of avascular necrosis according to the Salter criteria. RESULTS: Eleven patients with 15 hips met our inclusion criteria with a mean age of 20±8 (range, 6 to 34) months. Preoperatively, 12 of 15 hips (80%) were IHDI grade 4 and 3 of 15 (20%) were IHDI grade 3. Mean acetabular index was 29±8 (range, 19 to 46) degrees. Patients underwent open reduction (15 hips), adductor tenotomy (14 hips), femoral osteotomy (10 hips), and pelvic osteotomy (12 hips). At a mean follow-up of 40±16 (range, 13 to 71) months, 13 of 15 hips were IHDI grade 1 (86.7%), 1 was IHDI grade 2 (6.7%), and 1 hip was IHDI grade 3 (6.7%). The mean postoperative migration index was 7%±24% (range, -30% to 46%); the mean acetabular index was 22±8 (range, 9 to 38) degrees. No patients developed radiographically significant osteonecrosis. Complications included 2 femur fractures (13.3%) and 1 symptomatic implant that required early removal. One patient underwent further reconstructive hip surgery. CONCLUSIONS: In this series of infants with hip dislocations and underlying spasticity, open reduction±pelvic osteotomy and/or femoral osteotomy has a nearly 90% success rate in achieving and maintaining adequate hip reduction at intermediate-term follow-up. In the unique population of infants with dislocated hips and underlying spasticity, comprehensive hip reconstruction is largely successful with an acceptable rate of complications. LEVEL OF EVIDENCE: Level IV-retrospective.

BACKGROUND: Lyme arthritis (LA) of the hip can present similarly to septic arthritis (SA) and transient synovitis (TS). The primary purpose of this study was to determine clinical and laboratory parameters differentiating LA of the hip from SA or TS among children who had undergone hip aspiration during the evaluation of hip pain. METHODS: This was a retrospective review of all patients who underwent hip aspiration for the evaluation of hip pain at a tertiary care children's hospital in a Lyme endemic area. Clinical and laboratory data were reviewed and comparative analyses were performed between those diagnosed with LA, SA, and TS. Independent samples t test, ANOVA, and χ test were used to compare clinical and laboratory variables as appropriate. Multivariable logistic regression was used to elucidate independent predictors of LA. Statistical significance was set at P<0.05. RESULTS: Ninety-three hip aspirations (93 patients) were included in the final analysis. Seventeen patients were diagnosed with LA, 40 with SA, and 36 with TS. Multivariable logistic regression revealed febrile history (OR=16.3; 95% CI, 2.35-113.0) and increased peripheral white blood cell (WBC) count (OR=1.26; 95% CI, 1.01-1.58) to be significantly associated with increased odds of being diagnosed with SA versus LA. Increased erythrocyte sedimentation rate (ESR) was significantly associated with increased odds of being diagnosed with LA versus TS (OR=1.06; 95% CI, 1.02-1.10), whereas febrile history (OR=0.06; 95% CI, 0.01-0.49) and increased peripheral WBC count (OR=0.8; 95% CI, 0.65-0.98) were associated with decreased odds of LA. CONCLUSIONS: Children presenting in a Lyme endemic area with an isolated hip effusion are more likely to have LA versus SA if they have no history of fever and a decreased peripheral WBC count. Compared with TS, patients with LA are more likely to have an elevated ESR. This study adds to existing knowledge because there are few investigations examining isolated LA of the hip. LEVEL OF EVIDENCE: Level III-retrospective case-control study.

BACKGROUND: The pediatric T-condylar humerus fracture is different from its adult counterpart, and its rarity makes general consensus for treatment algorithms difficult to define. Pediatric orthopaedic surgeons tend to think of this fracture as a supracondylar humerus fracture with intra-articular extension. The transition age at which this injury resembles the adult distal humerus fracture and less so the pediatric supracondylar humerus fracture with intra-articular extension is unclear. The goal of this study is to synthesize the literature and identify factors associated with good and poor outcomes of these problematic injuries in children and adolescents. METHODS: We searched EMBASE, COCHRANE, and Medline computerized literature databases from the earliest date available in the database to 2014 using the following search term including variants and pleural counterparts: pediatric T-condylar humerus fracture. A final database of individual patients was assembled from the literature. Outcomes were rated using the method described by Jarvis and colleagues. Where possible the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association classification was used to stratify outcomes. Univariate and multivariate statistical tests were applied to the assembled database to assess differences in outcomes. RESULTS: Patients with a triceps-splitting approach had improved Jarvis outcome scores compared with the other operative approaches as well as the best arc of motion at follow-up. In addition, 6/25 triceps split patients were 10 years old or younger compared with 3/38 Bryan-Morrey patients and 0/23 osteotomy patients. No patients with Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association C3 fractures were treated with a triceps-splitting approach. When an articular approach was used, the Morrey Slide led to similar range of motion and functional outcomes as an olecranon osteotomy (P=0.616). However, the olecranon osteotomy resulted in more approach-related complications (P<0.001). An approach-related complication was associated with a poor outcome in 42% of cases. CONCLUSIONS: Pediatric T-condylar humerus fractures requiring an open approach may benefit from less invasive approaches such as the triceps split approach where the fracture pattern allows. Younger children are more amenable to less invasive means of fracture reduction and fixation. If an articular reduction is required, the aggregated literature suggests that the Morrey slide offers equivalent results to the olecranon osteotomy but with fewer approach-related complications. An olecranon osteotomy can be considered in cases of articular comminution. LEVEL OF EVIDENCE: Level IV-therapeutic.

BACKGROUND: No preferred procedure exists for the chronically painful, unreconstructable subluxated or dislocated hip in cerebral palsy. The purpose of this study was to compare pain relief and complication rates of salvage procedures in cerebral palsy for ambulatory and nonambulatory populations. METHODS: We searched Medline, Embase, and Cochrane databases using the search terms "cerebral palsy" and "hip dislocation." Inclusion and exclusion criteria were established to maintain data quality for analysis. A systematic review yielded 28 studies. Relevant information for postoperative pain and complications were extracted from each study and described. Our initial search identified 721 articles. Two hundred twenty duplications were excluded. Five hundred one were screened by title and abstract. One hundred articles underwent further full text and reference evaluation, yielding 25 studies. An additional 3 studies were then identified from the list of 25, yielding a total of 28 studies, which met our inclusion criteria. RESULTS: Among nonambulators, femoral head resection (FHR), valgus osteotomy (VO), and total hip arthroplasty (THA) were found to relieve pain better than arthrodesis [odds ratio (OR) 7.3, 95% confidence interval (CI), 2.2-24.8; OR 5.9, 95% CI, 1.6-22.8; OR 11.7, 95% CI, 1.1-297.5, respectively]. Arthrodesis had a significantly higher complication rate than FHR, VO, THA, and shoulder prosthetic interposition. No significant differences in complication rate were found between FHR and VO. Pain relief rates among nonambulators for FHR, VO, THA, shoulder prosthetic interposition, and arthrodesis were 90.4%, 88.4%, 93.8%, 90.9%, and 56.3%, respectively. Complication rates among nonambulators were 24.0%, 33.3%, 35.3%, 28.6%, and 106.3%, respectively. Comparison of pain relief and complication rates among ambulatory cerebral palsy patients in all procedures except THA was not possible because the populations could not be separated from nonambulators in numbers sufficient to perform statistical analysis. Data were available for 32 confirmed cases of THA in ambulators and was associated with a 93.3% pain relief rate and a 38.2% complication rate. CONCLUSIONS: Among nonambulators, the available literature suggests that FHR, VO, and THA may be superior at relieving pain than arthrodesis. FHR had the lowest absolute percentage of complications; however, no significant differences in complication rate or pain relief were found in nonambulators undergoing FHR or VO. Most of the complications for VO were implant related, and potentially amenable to hardware removal versus complications in FHR, which were related to the procedure itself such as proximal migration and heterotopic bone formation. THA in nonambulators was associated with complications such as dislocation and revision. Arthrodesis in nonambulators was associated with >100% complication rate and inferior pain relief compared with other procedures. Ambulatory patients had excellent pain relief with THA; however, the complication rate is higher than can be expected with non-neurological populations. Insufficient data exist to support use of other salvage procedures in ambulators. These conclusions should be interpreted with caution as all studies involved level IV evidence. LEVEL OF EVIDENCE: IV (systematic review of level IV studies).

OBJECTIVES: To determine if there is a shift in the treatment of children with medial epicondyle fractures toward children's hospitals, and to explore potential confounders of any observed effect. STUDY DESIGN: The Healthcare Cost and Utilization Project Kids' Inpatient Database was used to examine the epidemiology of medial epicondyle fractures, particularly with attention to whether they were admitted to a general hospital or a children's hospital (defined as free-standing children's hospitals, specialty children's hospitals, and children's units within general hospitals). Age and insurance payer status were also collected and evaluated as potential confounders. RESULTS: The proportion of medial epicondyle hospital discharges from children's hospitals increased (from 29%-46%; P < .001), and the proportion of discharges from general hospitals declined over the study period (from 71%-42%; P < .001). Age and insurance payer status both remained consistent throughout the study period and did not contribute to this finding. CONCLUSIONS: This study demonstrates an increase in the proportion of discharges for pediatric medial epicondyle fractures from children's hospitals. Although this finding is likely multifactorial, it may represent increasing subspecialization and increasing medical liability when treating children. Children's hospitals should identify those conditions which will continue to increase in number and consider constructing clinical pathways in order to optimize delivery of care and resource utilization.

OBJECTIVES: Pediatric lower extremity (LE) vascular injuries present many issues: microvascular surgeons are usually unavailable to stand-alone pediatric institutions, and the rate of morbidity including limb loss can be high if revascularization is delayed beyond the critical period of 8 hours. We assessed if time to revascularization was impacted by institution of a lower extremity vascular trauma protocol (LEVP). DESIGN: Level II retrospective prognostic. SETTING: Level I pediatric trauma center. PATIENTS/PARTICIPANTS: Pediatric patients presenting with ischemic lower extremities requiring urgent management (2000-2013). INTERVENTION: LEVP-a team of specialized microvascular surgeons, who have developed and manage a call schedule for our pediatric trauma center to offer care 24 h-1·d-1, 7 d-1·wk-1, and 365 d-1·y-1 to our children's hospital. MAIN OUTCOME MEASUREMENTS: Treatment team expertise, time to revascularization, and use of time-delaying preoperative radiographic vascular studies performed before and after initiation of LEVP. RESULTS: We identified 22 patients with ischemic LEs (16 patients treated before/6 patients treated after LEVP initiation). Mean time from admission to definitive vascular care was 6.4 hours preprotocol (20% > 8 hours)/4.6 hours postprotocol (0% > 8 hours). Before protocol initiation, 38% of LE vascular injuries were treated by LE microvascular repair-capable surgeons, and 37.5% had a preoperative radiographic vascular study compared with 100% and 0%, respectively, postprotocol initiation. Before protocol initiation, 37.5% had a preoperative radiographic vascular study compared with 0% after protocol initiation. CONCLUSIONS: Since LEVP initiation, we have required no preoperative radiographic vascular studies, there has not been a revascularization delay of >8 hours, and with appropriate staff surgeon coverage, the flow of care has improved with the new ability to address and care for these challenging injuries. To potentially improve the timeliness of vascular care and better match the skills of the practitioner to the injury, pediatric centers should consider implementation of an LEVP within their institutions.

OBJECTIVES: The aim of this study was to evaluate the additional cost associated with performing after-hours operative debridement of open fractures within 6 hours of injury. DATA SOURCES: The economic model is based on population estimates obtained from the National Trauma Database and the National Inpatient Sample on the number of open tibia fractures that occur annually in the United States and the number that present after-hours (between 6 PM and 2 AM) that undergo operative debridement within 6 hours. This model estimates incremental cost for after-hours surgery based on overtime wages for on-call personnel (nurses and surgical technicians) required to staff after-hours cases as published by the US Department of Labor and data from our own institution. As many level 1 hospitals are capable of performing after-hours cases without additional cost, a sensitivity analysis was performed to determine the effect of designated level of care of the trauma hospital. DATA EXTRACTION AND SYNTHESIS: A total of 17,414 open tibia fractures were recorded in the National Inpatient Sample for 2009, and an estimated 7485 open tibia fractures presented after-hours, 4242 of which underwent operative debridement within 6 hours of presentation. Based on wage statistics from the US Department of Labor and our own institution, the estimated total additional cost for after-hours operative debridement of open tibia fractures within 6 hours is from $2,210,895 to $4,046,648 annually, respectively. For level 2 hospitals and below, the cost of performing after-hours operative debridement of open tibia fractures is calculated as from $1,532,980 to $2,805,846 annually. CONCLUSIONS: The data indicated an increased overall financial cost of performing after-hours operative debridement of open tibia fractures. Given that there is minimal documented benefit to this practice, and with increased pressure to practice cost containment, elective delay of operative debridement of open fractures and/or transfer to a higher level of care trauma hospital may be an acceptable way to address these issues. LEVEL OF EVIDENCE: Economic analysis level III. See instructions for authors for a complete description of levels of evidence.

STUDY DESIGN: Therapeutic level II cohort study. OBJECTIVE: To evaluate the safety of adjunctive local application of vancomycin powder (VP) for infection prophylaxis in posterior instrumented thoracic and lumbar spine wounds in pediatric patients weighing more than 25 kg. SUMMARY OF BACKGROUND DATA: Spine surgeons have largely turned to vancomycin prophylaxis in an attempt to decrease the incidence of late surgical site infection and acute surgical site infection from methicillin-resistant Staphylococcus aureus. In adult patients, the adjunctive local application of VP with an intravenous cephalosporin has been shown to decrease postsurgical wound infection rates significantly; however, the safety of VP as an adjunct in pediatric spine surgery has not been reported. METHODS: We reviewed data collected under a systematic protocol specifically designed to monitor the safety profile of VP. We measured changes in creatinine and systemic vancomycin levels after intrawound application of 500 mg of unreconstituted VP during spine deformity correction surgery in patients weighing more than 25 kg (patients also received routine intravenous cephalosporin prophylaxis). Laboratory values were measured preoperatively and on postoperative days 1 and 4. Any adverse reactions and infections through available follow-up (2-8 mo) were recorded. RESULTS: Eighty-seven consecutive pediatric patients with spinal deformity weighing more than 25 kg who received intraoperative VP during a 9-month period were identified. Sixty-three percent of the patients in this series had adolescent idiopathic scoliosis, 15% congenital scoliosis, 15% neuromuscular scoliosis, and 5% spondylolisthesis. The average change in creatinine levels between the preoperative and postoperative day 1 draw was -0.03 and between the preoperative and postoperative day 4 draw was -0.075. The postoperative systemic vancomycin levels remained undetectable. None of the patients experienced nephrotoxicity or red man syndrome. Three of the 87 patients developed a surgical site infection. CONCLUSION: In this cohort there were no clinically significant changes in creatinine level or systemic vancomycin level caused by use of intraoperative VP. LEVEL OF EVIDENCE: 2.
