RESUMEN
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.

Quality and process improvement (QI/PI) in children's surgical care require reliable data across the care continuum. Since 2012, the American College of Surgeons' (ACS) National Surgical Quality Improvement Program-Pediatric (NSQIP-Pediatric) has supported QI/PI by providing participating hospitals with risk-adjusted, comparative data regarding postoperative outcomes for multiple surgical specialties. To advance this goal over the past decade, iterative changes have been introduced to case inclusion and data collection, analysis and reporting. New datasets for specific procedures, such as appendectomy, spinal fusion for scoliosis, vesicoureteral reflux procedures, and tracheostomy in children less than 2 years old, have incorporated additional risk factors and outcomes to enhance the clinical relevance of data, and resource utilization to consider healthcare value. Recently, process measures for urgent surgical diagnoses and surgical antibiotic prophylaxis variables have been developed to promote timely and appropriate care. While a mature program, NSQIP-Pediatric remains dynamic and responsive to meet the needs of the surgical community. Future directions include introduction of variables and analyses to address patient-centered care and healthcare equity.

Importance: Use of postoperative antimicrobial prophylaxis is common in pediatric surgery despite consensus guidelines recommending discontinuation following incision closure. The association between postoperative prophylaxis use and surgical site infection (SSI) in children undergoing surgical procedures remains poorly characterized. Objective: To evaluate whether use of postoperative surgical prophylaxis is correlated with SSI rates in children undergoing nonemergent surgery. Design, Setting, and Participants: This is a multicenter cohort study using 30-day postoperative SSI data from the American College of Surgeons' Pediatric National Surgical Quality Improvement Program (ACS NSQIP-Pediatric) augmented with antibiotic-use data obtained through supplemental medical record review from June 2019 to June 2021. This study took place at 93 hospitals participating in the ACS NSQIP-Pediatric Surgical Antibiotic Prophylaxis Stewardship Collaborative. Participants were children (<18 years of age) undergoing nonemergent surgical procedures. Exclusion criteria included antibiotic allergies, conditions associated with impaired immune function, and preexisting infections requiring intravenous antibiotics at time of surgery. Exposures: Continuation of antimicrobial prophylaxis beyond time of incision closure. Main Outcomes and Measures: Thirty-day postoperative rate of incisional or organ space SSI. Hierarchical regression was used to estimate hospital-level odds ratios (ORs) for SSI rates and postoperative prophylaxis use. SSI measures were adjusted for differences in procedure mix, patient characteristics, and comorbidity profiles, while use measures were adjusted for clinically related procedure groups. Pearson correlations were used to examine the associations between hospital-level postoperative prophylaxis use and SSI measures. Results: Forty thousand six hundred eleven patients (47.3% female; median age, 7 years) were included, of which 41.6% received postoperative prophylaxis (hospital range, 0%-71.2%). Odds ratios (ORs) for postoperative prophylaxis use ranged 190-fold across hospitals (OR, 0.10-19.30) and ORs for SSI rates ranged 4-fold (OR, 0.55-1.90). No correlation was found between use of postoperative prophylaxis and SSI rates overall (r = 0.13; P = .20), and when stratified by SSI type (incisional SSI, r = 0.08; P = .43 and organ space SSI, r = 0.13; P = .23), and surgical specialty (general surgery, r = 0.02; P = .83; urology, r = 0.05; P = .64; plastic surgery, r = 0.11; P = .35; otolaryngology, r = -0.13; P = .25; orthopedic surgery, r = 0.05; P = .61; and neurosurgery, r = 0.02; P = .85). Conclusions and Relevance: Use of postoperative surgical antimicrobial prophylaxis was not correlated with SSI rates at the hospital level after adjusting for differences in procedure mix and patient characteristics.

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 characteristics and clinical consequences of pyogenic bone and joint infections in older children and adolescents have received little attention. This study evaluated the presentation and complications of musculoskeletal infections involving the pelvis and extremities in children older than 10 years. Thirty patients 10 to 17 years old (mean, 12.7 years old) were treated for musculoskeletal infections. Mean time to diagnosis was 9.2 days. Prior to correct diagnosis, 83% were assessed by at least 1 outpatient provider. At the time of admission, 55% were weight bearing and 93% were afebrile. Twenty-eight percent had a multifocal infection. More than one-third had serious medical complications or orthopedic sequelae; compared with patients without complications, this group had a significantly higher admission C-reactive protein and longer hospital stay. Symptoms of musculoskeletal infection common among young children may be absent in adolescents. Axial imaging is recommended to identify adjacent or multifocal disease. The Kocher criteria are less sensitive for septic hip arthritis in the adolescent population. Prompt recognition and treatment are critical to avoid medical and musculoskeletal complications.

STUDY DESIGN: Multicenter retrospective. OBJECTIVE: To determine the long-term complication rate associated with surgical treatment of spondylolisthesis in adolescents. There is limited information on the complication rate associated with posterior spinal fusion (PSF) of spondylolisthesis in the pediatric and adolescent population. METHODS: Patients who underwent PSF for spondylolisthesis between 2004 and 2015 at four spine centers, < 21 years of age, were included. Exclusion criteria were < 2 years of follow-up or anterior approach. Charts and radiographs were reviewed. RESULTS: 50 patients had PSF for spondylolisthesis, 26 had PSF alone, while 24 had PSF with trans-foraminal lumbar interbody fusion (TLIF). Mean age was 13.9 years (range 9.6-18.4). Mean follow-up was 5.5 years (range 2-15). Mean preoperative slip was 61.2%. 20/50 patients (40%) experienced 23 complications requiring reoperation at a mean of 2.1 years (range 0-9.3) for the following: implant failure (12), persistent radiculopathy (3), infection (3), persistent back pain (2), extension of fusion (2), and hematoma (1). In addition, there were 22 cases of radiculopathy (44%) that were transient. Rate of implant failure was related to preoperative slip angle (p = 0.02). Reoperation rate and rates of implant failure were not associated with preoperative % slip (reoperation: p = 0.42, implant failure: p = 0.15), postoperative % slip (reoperation: p = 0.42, implant failure: p = 0.99), postoperative kyphosis of the lumbosacral angle (reoperation: p = 0.81, implant failure: p = 0.48), change in % slip (reoperation: p = 0.30, implant failure: p = 0.12), change in slip angle (reoperation: p = 0.42, implant failure: p = 0.40), graft used (reoperation: p = 0.22, implant failure: p = 0.81), or addition of a TLIF (reoperation: p = 0.55, implant failure: p = 0.76). CONCLUSION: PSF of spondylolisthesis in the adolescent population was associated with a 40% reoperation rate and high rate of post-operative radiculopathy. Addition of a TLIF did not impact reoperation rate or rate of radiculopathy.

BACKGROUND: Managing the pulseless pediatric supracondylar humerus fracture (PSHF) remains a significant clinical decision-making challenge for the treating surgeon. The purpose of the study is to determine frequency of the treatments according to the American Academy of Orthopaedic Surgeons (AAOS) Appropriate Use Criteria (AUC) for the PSHF with vascular injury and evaluate the appropriateness of these interventions. METHODS: We identified all PSHF with concern for vascular injury at one high volume, level 1 trauma center managed by 6 fellowship-trained pediatric orthopaedic surgeons over 4.5 years. Demographic information and other injury and treatment variables were obtained. Each patient was classified as 1 of the 6 patient scenarios specified by the AAOS AUC. Each of the 18 interventions identified in the AUC were documented, including the level of "appropriateness" as specified by AAOS AUC. RESULTS: A total of 638 PSHF were managed identified; of these, 52 were pink, pulseless, or dysvascular (8.2%). Only 7 of the 18 treatment options suggested by the AUC were used in this cohort. Across all 7 interventions used in this cohort, 20.2% (17/84) of interventions were "appropriate," 52.4% (44/84) were "maybe appropriate," 22.6% (19/84) were "rarely appropriate," and 4.8% (4/84) were not listed in treatment options. CONCLUSIONS: Supracondylar fractures are the most common injury to the elbow seen in children and are variable in presentation and management. The pink, pulseless fracture continues to be a major topic for research and discussion due to the morbidity if not treated "appropriately." The AUC were created to help guide practitioners when strong evidence is lacking. In this study at a single, pediatric hospital, there was variation and disagreement with "appropriateness" of treatments that were performed but this discrepancy did not result in any poor outcomes. Although the AUC do offer valuable guidance, our findings highlight a need for continued research in this area to help validate the AUC and help strengthen the recommendations moving forward. LEVEL OF EVIDENCE: Level III-retrospective.

BACKGROUND: Medial epicondyle fractures are a common pediatric and adolescent injury accounting for 11% to 20% of elbow fractures in this population. This purpose of this study was to determine the variability among pediatric orthopaedic surgeons when treating pediatric medial epicondyle fractures. METHODS: A discrete choice experiment was conducted to determine which patient and injury attributes influence the management of medial epicondyle fractures by pediatric orthopaedic surgeons. A convenience sample of 13 pediatric orthopaedic surgeons reviewed 60 case vignettes of medial epicondyle fractures that included elbow radiographs and patient/injury characteristics. Displacement was incorporated into the study model as a fixed effect. Surgeons were queried if they would treat the injury with immobilization alone or open reduction and internal fixation (ORIF). Statistical analysis was performed using a mixed effect regression model. In addition, surgeons filled out a demographic questionnaire and a risk assessment to determine if these factors affected clinical decision-making. RESULTS: Elbow dislocation and fracture displacement were the only attributes that significantly influenced surgeons to perform surgery (P<0.05). The presence of an elbow dislocation had the largest impact on surgeons when choosing operative care (ß=-0.14; P=0.02). In addition, for every 1 mm increase in displacement, surgeons tended to favor ORIF by a factor of 0.09 (P<0.01). Sex, mechanism of injury, and sport participation did not influence decision-making. In total, 54% of the surgeons demonstrated a preference for ORIF for the included scenarios. On the basis of the personality Likert scale, participants were neither high-risk takers nor extremely risk adverse with an average-risk score of 2.24. Participant demographics did not influence decision-making. CONCLUSIONS: There is substantial variation among pediatric orthopaedic surgeons when treating medial epicondyle fractures. The decision to operate is significantly based on the degree of fracture displacement and if there is a concomitant elbow dislocation. There is no standardization regarding how to treat medial epicondyle fractures and better treatment algorithms are needed to provide better patient outcomes. LEVEL OF EVIDENCE: Level V.

BACKGROUND: Distal radius fractures are the most common injury in the pediatric population. The purpose of this study was to determine the variation among pediatric orthopaedic surgeons when diagnosing and treating distal radius fractures. METHODS: Nine pediatric orthopaedic surgeons reviewed 100 sets of wrist radiographs and were asked to describe the fracture, prescribe the type of treatment and length of immobilization, and determine the next follow-up visit. κ statistics were performed to assess the agreement with the chance agreement removed. RESULTS: Only fair agreement was present when diagnosing and classifying the distal radius fractures (κ=0.379). There was poor agreement regarding the type of treatment that would be recommended (κ=0.059). There was no agreement regarding the length of immobilization (κ=-0.004).Poor agreement was also present regarding when the first follow-up visit should occur (κ=0.088), whether or not new radiographs should be obtained at the first follow-up visit (κ=0.133), and if radiographs were necessary at the final follow-up visit (κ=0.163). Surgeons had fair agreement regarding stability of the fracture (κ=0.320).A subgroup analysis comparing various traits of the treatment immobilization showed providers only had a slight level of agreement on whether splint or cast immobilization should be used (κ=0.072). There was poor agreement regarding whether long-arm or short-arm immobilization should be prescribed (κ=-0.067).Twenty-three of the 100 radiographs were diagnosed as a torus/buckle fracture by all 9 surgeons. κ analysis performed on all the treatment and management questions showed that each query had poor agreement. CONCLUSIONS: The interobserver reliability of diagnosing pediatric distal radius fractures showed only fair agreement. This study demonstrates that there is no standardization regarding how to treat these fractures and the length of immobilization required for proper fracture healing. Better classification systems of distal radius fractures are needed that standardize the treatment of these injuries. LEVEL OF EVIDENCE: Level II.

The concept of evidence-based medicine has evolved over the past 2 decades, and has become a cornerstone to clinical decision-making in virtually every aspect of medicine. With a commitment to providing its members with high-quality evidence-based guidelines, the American Academy of Orthopaedic Surgeons has instituted concerted efforts since 2006 to develop clinical practice guidelines (CPGs) and appropriate use criteria (AUCs) for certain orthopaedic conditions. Many of these CPGs and AUCs detail the management of pediatric orthopaedic conditions. By the same token, members of the Pediatric Orthopaedic Society of North America (POSNA) Evidence Based Practice Committee have been publishing succinct evaluations of randomized controlled trials in pediatric orthopaedic surgery to create an evidence-based repository for quick reference to available high-level evidence as well as resource to identify gaps in the current research and identify opportunities for future investigation. In instances where higher-level evidence needed to develop CPGs is not available to address a critically important clinical question, consensus recommendations from experts in the field have been obtained to develop best practice guidelines (BPGs). The purpose of this review is to provide readers with a deeper understanding of the key principles of evidence-based medicine and methodologies used for the development of CPGs, AUCs, and BPGs.

OBJECTIVE: The purpose of this study is to determine if an educational model during a surgical skills laboratory results in a significant reduction in cast saw blade temperatures generated during cast removal. DESIGN: As part of an orthopedic resident surgical skills laboratory an Institutional Review Board-approved study was performed. A total of 17 study subjects applied a short arm cast. Everyone removed 1 short arm cast with temperatures recorded on the saw blade. Following cast removal, an educational session was conducted on proper cast removal and blade cooling techniques. Everyone then removed a second cast. Blade temperatures were recorded. To assess reproducibility, the 5 PGY-1 orthopedic residents removed a short arm cast 3 months later. SETTING: Carolinas Medical Center, Charlotte, NC, tertiary care center PARTICIPANTS: A total of 17 study subjects with minimal casting experience (5 PGY-1 orthopedic residents and 12 senior medical students) applied a short arm cast. RESULTS: Following the educational session there was a significant reduction in mean and mean maximum blade temperatures (p < 0.05). During the second round of cast removal assessment of blade temperatures and specific techniques to cool the blade were observed among all participants. At 3 months' time, the mean and mean maximum blade temperatures remained significantly lower than before the educational session (p < 0.05). CONCLUSIONS: The intervention in this study reduced the maximum blade temperatures to levels below the threshold known to cause burns. This simple, low cost, and easily reproducible model can easily be disseminated across institutions and simulation laboratories.

Sickle cell disease (SCD) is an autosomal recessive disorder that results in hemolytic anemia related to abnormal hemoglobin and erythrocyte levels. SCD is characterized by vascular occlusive episodes, visceral sequestration, and aplastic or hemolytic crises. These crises most commonly occur in bone. The orthopaedic manifestations of SCD comprise much of the morbidity associated with this disorder. Osteonecrosis and osteomyelitis are among the most disabling and serious musculoskeletal complications in patients with SCD. Effective management of the bone and joint sequelae requires an accurate diagnosis, an understanding of the pathophysiology of the disease, and knowledge of available medical and surgical treatment alternatives. The major orthopaedic manifestations of SCD are osteonecrosis, osteomyelitis, septic arthritis, and bone infarction. Patients with SCD require close monitoring in the perioperative period because of the risk for vasoocclusive crisis.

BACKGROUND: The major complication of unstable slipped capital femoral epiphysis (SCFE) is avascular necrosis (AVN) of the femoral head. The purpose of this study was to document by angiography the preoperative and postoperative perfusion to the proximal femoral epiphysis following an unstable SCFE. A specific aim was to determine whether blood flow could be restored. A secondary aim was to determine the efficacy of an intracranial pressure (ICP) monitor to assess blood flow within the femoral head intraoperatively. METHODS: Nine patients with an unstable SCFE underwent superselective angiogram of the medial circumflex femoral artery preoperatively, followed by operative fixation with an open reduction using a modified Dunn approach. Femoral head blood flow was evaluated with an ICP monitor. Angiography was repeated postoperatively. Patients were followed radiographically to assess for AVN. RESULTS: Follow-up averaged 22 months. Six patients did not have arterial flow to the femoral head on the preoperative angiogram. Flow was restored postoperatively on angiogram in 4 of the 6 patients. Two patients developed AVN. One had no flow to the femoral head preoperatively or postoperatively on angiogram and complete tearing of the periosteum was noted. In 1 patient, there was no ICP waveform after the initial reduction. After removing more callous and repeating reduction, the waveform returned. Of the 2 patients with AVN, 1 had an ICP waveform after reduction. CONCLUSIONS: This study documents that some patients with unstable SCFE present with reduced femoral head blood supply due to SCFE. It also demonstrates blood flow restoration in 4 patients by angiogram and 5 by ICP monitor after surgical treatment. No patient immediately lost blood flow due to surgery. ICP monitor is a safe intraoperative tool for real-time assessment of femoral head blood flow during open reduction of unstable SCFE. Presence of flow by ICP is not a guarantee that AVN will not develop, but absence of flow was predictive of AVN. LEVEL OF EVIDENCE: Therapeutic level I-prognostic. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: Although supracondylar humerus fractures are common in young children, the incidence in adolescents is much lower. As a result, there is a paucity of literature to guide treatment. The purpose of this study was to review the treatment and outcomes for a consecutive series of distal humerus fractures in adolescents and to compare outcomes between patients treated with percutaneous skeletal fixation and those treated with open reduction and fixation. METHODS: A retrospective review of patients 10 to 17 years of age who underwent surgical treatment for a distal humerus fracture from 2005 to 2014 was performed. Patients with medial epicondyle fractures and those with insufficient follow-up to document union or return of motion were excluded. Medical records were reviewed to collect demographic data as well as operative approach and method of fixation. Clinical outcomes included range of motion, time to maximum motion, and complications [nerve dysfunction, heterotopic ossification (HO), need for secondary surgery]. Radiographs were reviewed to determine time to union as well as coronal and sagittal alignment. RESULTS: One hundred eighteen adolescents with displaced distal humerus fractures were identified. Eighty-one met inclusion criteria. Forty-four of these were classified as extra-articular [Orthopaedic Trauma Association (OTA) 13-A], and 37 were intra-articular fractures (10 OTA 13-B and 27 OTA 13-C).Although not statistically significant, closed treatment with percutaneous fixation of extra-articular fractures resulted in greater flexion-extension arc of motion at final follow-up (128 vs. 119 degrees, P=0.17) and demonstrated more rapid return of motion (2.8 vs. 3.9 mo, P=0.05) when compared with open treatment despite a longer duration of immobilization and less formal physical therapy. Complications such as HO (P=0.05), nerve dysfunction (P=0.02), and secondary surgery (P=0.001) were more common in the open treatment group.Closed treatment with percutaneous fixation of intra-articular fractures was performed in younger patients of similar size (12.8 vs. 14.4 y, P<0.01; 154 vs. 142 lbs, P=0.5). There were no significant differences between groups in regard to outcomes or complications. There were trends toward increased frequency of HO, nerve dysfunction, and secondary surgery in the open treatment group.Patients with intra-articular fractures were older (14.2 vs. 11.5 y, P<0.001) and heavier (144 vs. 94 lbs, P<0.001) than patients with extra-articular fractures and were more likely to be treated open (74% vs. 11%, P<0.001). Extra-articular fractures demonstrated a greater total arc of motion (126 vs. 118 degrees, P=0.04) at final follow-up despite longer duration of immobilization (23 vs. 15 d, P=0.002), and less physical therapy (27% vs. 73%, P<0.001). Radiographic carrying angle (16.6 vs. 22.3 degrees, P=0.08) and anterior humeral line (95% vs. 81%, P=0.07) trended toward more anatomic alignment in the extra-articular group. Secondary surgery was more common after intra-articular fracture (24% vs. 7%, P=0.03). CONCLUSIONS: Closed reduction and pinning of extra-articular distal humerus fractures in adolescents resulted in predictable clinical and radiographic outcomes and allowed for earlier return of motion and fewer complications when compared with open treatment. Intra-articular distal humerus fractures occur more frequently in older adolescents and are more likely to require open reduction and internal fixation to obtain joint congruity. Patients with intra-articular injuries should be cautioned that regaining full elbow motion may be more difficult, and there is an increased risk for complications and need for additional surgery. Closed reduction and percutaneous fixation of intra-articular injuries appears to be a reasonable option in select patients. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

Transphyseal fractures of the distal humerus typically occur in children younger than 3 years secondary to birth trauma, nonaccidental trauma, or a fall from a small height. Prompt and accurate diagnosis of the injury is crucial for a successful outcome. Recognizing that the forearm is not aligned with the humerus on plain radiography can aid in the diagnosis of the injury. Surgical management is most commonly performed with the aid of an arthrogram. Closed reduction and percutaneous pinning techniques similar to those used for supracondylar humerus fractures are employed. The most common complication is cubitus varus caused by a malunion, osteonecrosis of the medial condyle, or growth arrest. A corrective lateral closing wedge osteotomy can be performed to restore a nearly normal carrying angle.

Supracondylar humerus fractures are the most common elbow fractures in children. Displaced supracondylar humerus fractures that are associated with neurologic and/or vascular injuries are treated with timely reduction through closed techniques. When closed techniques fail, reduction by open methods is indicated. Controversy exists as to which surgical approach yields the best outcomes in terms of cosmetic and functional results, while minimizing postoperative complications. Open reduction, when indicated, has been shown to yield good outcomes when closed reduction methods fail.

In recent years, the safety, quality, and value of surgical care have become increasingly important to surgeons and hospitals. Quality improvement in surgical care requires the ability to collect, measure, and act upon reliable and clinically relevant data. One example of a large-scale quality effort is the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (ACS NSQIP-Pediatric), the only nationwide, risk-adjusted, outcomes-based program evaluating pediatric surgical care.

BACKGROUND: This study provides intermediate-term follow-up data on the vascular status of a cohort of children with a perfused, pulseless supracondylar humeral fracture who were managed with closed reduction, percutaneous pinning, and observation. METHODS: Pediatric patients who sustained a perfused, pulseless supracondylar humeral fracture in the period from 2007 to 2011 and who had at least six months of clinical follow-up were identified and returned for evaluation. The primary outcome was vascular status as indicated by palpation of the radial pulse, the wrist brachial index, and arterial patency on duplex ultrasound. Secondary outcomes included functional parameters assessed with the Pediatric Outcomes Data Collection Instrument (PODCI), arm circumference, arm length, elbow motion, neurologic findings, muscle endurance, grip strength, and intolerance to cold. RESULTS: Follow-up data were obtained for twenty of thirty-six patients with a Gartland type-III fracture who had been managed with closed reduction and percutaneous pinning. Five patients had a return of a palpable pulse in the operating room after closed reduction and percutaneous pinning. All twenty had a palpable radial pulse at the time of the latest follow-up, and all nerve palsies resolved. Duplex ultrasound performed at the time of follow-up showed that fourteen patients had a patent brachial artery, five had brachial artery occlusion with large collateral vessels, and one had severe arterial stenosis. All fourteen patients with a patent brachial artery, two of the five with an occluded brachial artery, and the patient with a stenotic brachial artery had a normal wrist brachial index. Three patients with an occluded brachial artery had an abnormal wrist brachial index (0.73, 0.71, and 0.80). No differences between the injured and uninjured sides were observed with regard to arm circumference, arm length, elbow motion, muscle endurance, or grip strength. Thirteen of the twenty patients had higher functioning in all domains of the PODCI questionnaire compared with the general population. Two patients (one with an occluded artery and one with a patent artery) had lower values on the global functioning score. CONCLUSIONS: After an average of twenty months of follow-up, children with a perfused, pulseless supracondylar humeral fracture that had been treated with closed reduction, percutaneous pinning, and observation demonstrated a palpable distal radial pulse, normal growth of the arm, and good/excellent functional outcomes, although five of the twenty patients had an occluded brachial artery.
