An Early Evaluation of Remote Site Visits for ACGME Program Applications.

Background: Prior to the COVID-19 pandemic, accreditation site visit interviews occurred in-person. In response to the pandemic, the Accreditation Council for Graduate Medical Education (ACGME) developed a remote site visit protocol. Objective: To perform an early assessment of the remote accreditation site visits for programs applying for initial ACGME accreditation. Methods: A cohort of residency and fellowship programs that had remote site visits was evaluated from June to August 2020. Surveys were sent to program personnel, ACGME accreditation field representatives, and executive directors following the site visits. Comparison of accreditation decisions (Initial Accreditation or Accreditation Withheld) was completed for matched residency or fellowship programs having in-person site visits in 2019. Results: Surveys were sent to all program personnel from the 58 residency and fellowship programs that had remote site visits for new program applications, as well as the accreditation field representatives who performed the remote visits. The survey response rate was 58% (352 of 607). Ninety-one percent of all respondents were extremely or very confident that remote site visits provided a thorough assessment of proposed residency or fellowship programs. Fifty-four programs having remote site visits were matched by specialty to programs having had in-person program application site visits in 2019. Forty-six programs that had remote site visits received Initial Accreditation, and 52 programs that had in-person site visits in 2019 received Initial Accreditation (P=.093, 95% CI 0.91-22.38). Conclusions: Most program personnel and accreditation field representatives were confident that remote site visits conducted for program applications provided fair and thorough assessments of the program.

The Effect of Two Attending Surgeons on the Outcomes of Posterior Spine Fusion in Children With Cerebral Palsy.

BACKGROUND: Posterior spinal fusion (PSF) in children with cerebral palsy (CP) carries a high risk of complications and morbidity. The purpose of this study is to investigate the impact of using two attending surgeons on blood loss, operative time, and complications in this fragile population. METHODS: This was a prospective, matched cohort analysis of patients with CP who underwent PSF with two attending surgeons. These were matched with a control group that had a single-surgeon team, assisted by a senior resident or PA. The groups were compared using paired Student t tests and chi-square tests. RESULTS: 50 patients were included in the study (25 study and 25 matched controls), determined by our power analysis. There was no statistical difference in the mean age, preoperative major curve angle, major curve angle correction, or use of antifibrinolytics. The two-surgeon group decreased surgical time from 5.25 to 3.3 hours (p = .000002), and estimated blood loss from 1,238 to 865 mL (p = .009). The complication rate decreased from 33% to 8% (p=.034). Length of stay was also decreased from 6.5 days to 5.35 (p = .02). CONCLUSIONS: Although confounding variables were present, this study demonstrates that the use of a two-surgeon team during spinal surgery for patients with cerebral palsy could have a role in reducing operative time, blood loss, complication rates, and hospital length of stay. Overall, these factors and any improved operating room efficiencies may lead to lasting improved patient outcomes. LEVEL OF EVIDENCE: Level III, retrospective, comparative study.

Role of Computed Tomography in the Classification of Pediatric Pelvic Fractures-Revisited.

OBJECTIVES: To determine the need for computerized tomography (CT) scans in the assessment of pediatric pelvic fractures. DESIGN: Retrospective Chart Review. SETTING: Level-1 Pediatric Trauma Center. PATIENTS/PARTICIPANTS: Thirty pediatric trauma patients with pelvic fractures who have obtained both a radiograph and CT scan. MAIN OUTCOME MEASUREMENTS: Fleiss Kappa coefficient to compare interreliability. RESULTS: The average age of the patients was 7 years (range 1-13 years). Seventeen were males and 13 were females. The Torode and Zieg classification included 3 type I, 6 type II, 13 type III, and 8 type IV. The Kappa value for interobserver agreement comparing radiographs was 0.453, and for CT was 0.42. Three patients (10%) were treated with a spica cast, and none required surgery for their pelvic fracture. Four patients (11%) demonstrated liver, spleen, or kidney injuries on CT. Out of those 4, 1 had indications for laparotomy and drain placement, 1 died secondary to shock, and 2 were treated conservatively. CONCLUSIONS: The results of this study demonstrated that plain radiographs alone can be used to classify and manage most pediatric fractures, confirming Silber previous findings. Furthermore, we recommend the specific instances of Schreck and Haasz et al in which CT scans should be used, sparing the general pediatric population unnecessary radiation. Such cases include patients with an abnormal abdominal or pelvic examination, complex fracture patterns, displacement greater than 1 cm, femur deformities, hematuria, Glasgow Coma Scale <13, hemodynamic instability, an aspartate aminotransferase > 200 U/L, an Hct < 30%, or an abnormal chest x-ray.

Evaluation and Referral for Developmental Dysplasia of the Hip in Infants.

Developmental dysplasia of the hip (DDH) encompasses a wide spectrum of clinical severity, from mild developmental abnormalities to frank dislocation. Clinical hip instability occurs in 1% to 2% of full-term infants, and up to 15% have hip instability or hip immaturity detectable by imaging studies. Hip dysplasia is the most common cause of hip arthritis in women younger than 40 years and accounts for 5% to 10% of all total hip replacements in the United States. Newborn and periodic screening have been practiced for decades, because DDH is clinically silent during the first year of life, can be treated more effectively if detected early, and can have severe consequences if left untreated. However, screening programs and techniques are not uniform, and there is little evidence-based literature to support current practice, leading to controversy. Recent literature shows that many mild forms of DDH resolve without treatment, and there is a lack of agreement on ultrasonographic diagnostic criteria for DDH as a disease versus developmental variations. The American Academy of Pediatrics has not published any policy statements on DDH since its 2000 clinical practice guideline and accompanying technical report. Developments since then include a controversial US Preventive Services Task Force "inconclusive" determination regarding usefulness of DDH screening, several prospective studies supporting observation over treatment of minor ultrasonographic hip variations, and a recent evidence-based clinical practice guideline from the American Academy of Orthopaedic Surgeons on the detection and management of DDH in infants 0 to 6 months of age. The purpose of this clinical report was to provide literature-based updated direction for the clinician in screening and referral for DDH, with the primary goal of preventing and/or detecting a dislocated hip by 6 to 12 months of age in an otherwise healthy child, understanding that no screening program has eliminated late development or presentation of a dislocated hip and that the diagnosis and treatment of milder forms of hip dysplasia remain controversial.

Back pain in Duchenne muscular dystrophy: steroids are not always the culprit.

We report on a child with Duchenne muscular dystrophy on prolonged corticosteroid treatment who presented with back pain and was subsequently found to have a monostotic fibrous dysplasia lesion of the spine. It is the intent of this case report to emphasize the need to maintain a high index of suspicion for other potential causes of back pain in Duchenne muscular dystrophy besides vertebral compression fractures.

Hip reconstruction is more painful than spine fusion in children with cerebral palsy.

PURPOSE: Concerns about pain control in patients with cerebral palsy (CP) are especially anxiety provoking for parents, given the fact that spasticity, communication issues, and postoperative muscle spasms are significant problems that make pain control difficult in these patients. A better understanding of the magnitude and quality of the pain these patients experience after our surgical procedures would better prepare the patients and their families. The purpose of this study is to quantify the amount of postoperative pain in children with CP undergoing hip reconstruction and spinal fusion. Specifically, the study will compare pain scores and the amount of narcotics used between the two groups. MATERIALS AND METHODS: This is a retrospective chart review of a consecutive series of children with CP (GMFCS levels IV and V) over a 5-year period undergoing hip reconstruction (femoral osteotomy, pelvic osteotomy, or both) and posterior spinal fusion (PSF) at a tertiary-care pediatric hospital. The primary end point was the total opioid used by the patient during the hospitalization, by converting all forms of narcotics to morphine equivalents. The secondary end point was the documentation of pain with standard pain scores at standard time points postoperatively. Adverse effects related to pain management were documented for both groups. Student's t-tests were utilized to statistically compare differences between the groups, with significance determined at p < 0.05. RESULTS: Forty-two patients with CP who underwent hip reconstruction (mean age 8.8 years) were compared to 26 patients who underwent PSF (mean age 15.4 years). The total opioid used, normalized by body weight and by days length of stay (DLOS), in the hip group was 0.49 mg morphine/kg/DLOS, compared to 0.24 for the spine group (p = 0.014). The mean pain score for the hip group was 1.52, compared to 0.72 for the spine group (p = 0.013). There were no significant differences in the occurrence of adverse effects related to pain management between the two groups. CONCLUSION: Patients with CP undergoing hip reconstruction surgery had significantly more pain, as exhibited by requiring more narcotics and having higher pain scores, than those patients undergoing PSF. The knowledge that hip reconstruction is more painful than PSF for patients with CP will better prepare families about what to expect in the postoperative period and will alert providers to supply better postoperative pain control in these patients. LEVEL OF EVIDENCE: III (case control series).

Adjunctive Pain Control Methods Lower Narcotic Use and Pain Scores for Patients With Adolescent Idiopathic Scoliosis Undergoing Posterior Spinal Fusion.

STUDY DESIGN: This was a retrospective review of patients with adolescent idiopathic scoliosis (AIS) undergoing posterior spinal fusion (PSF). OBJECTIVES: To determine whether the use of adjunctive pain medications (bupivacaine pump, dexmedetomidine, and ketorolac) will reduce the need for opioids, reduce postoperative pain, and shorten length of hospital stay in patients with AIS undergoing PSF. SUMMARY OF BACKGROUND DATA: Posterior spinal fusion and instrumentation for AIS can cause significant postoperative pain. Adjunctive pain control modalities, including the use of ketorolac, dexmedetomidine, and subcutaneous bupivacaine pumps, all can lessen the effects of postoperative pain. METHODS: Retrospective review of adolescents aged 10-18 years with AIS receiving PSF surgery over the past 10 years at a tertiary care children's hospital. All patients with AIS undergoing PSF were included in the study. Patients older than 18 or younger than 10 years and those undergoing PSF for other diagnoses, including neuromuscular scoliosis, congenital scoliosis, and kyphosis, were excluded from the study. Patients' pain was managed postoperatively with adjunctive medications in addition to intravenous and oral opioids. Variables of interest were local anesthetic bupivacaine delivered through a subcutaneous pump, sedative/analgesic dexmedetomidine, and ketorolac. Primary outcomes analyzed were normalized opioid requirement after surgery, visual analog scale (VAS) pain scores, and length of stay in the hospital. RESULTS: A total of 196 children were analyzed with no significant differences in demographics. Univariate analysis showed that all 3 adjunct medications improved outcomes. A multivariate regression model of the outcomes with respect to the 3 medication variables of interest was built, showing that the bupivacaine pump significantly reduced normalized opioid requirement by 0.98 mg/kg (p = .001) and reduced VAS pain scores by 0.67 points (p = .004). Dexmedetomidine significantly reduced the average VAS pain scores in the first 24 hours by 0.62 points (p = .005). CONCLUSIONS: Use of the bupivacaine pump provided improved analgesia with lower pain scores, lower opioid requirements, and a lower length of stay.

Evaluation of Patient Satisfaction Surveys in Pediatric Orthopaedics.

BACKGROUND: Patient satisfaction survey scores are increasingly being tied to incentive compensation, impact how we practice medicine, influence decisions on where patients seek care, and in the future may be required for accreditation. The goal of this study is to compare the results of an internal distribution of patient satisfaction surveys at the point of care to responses received by mail in a hospital-based, high-volume pediatric orthopaedic practice. METHODS: A pediatric outpatient survey is used at our institution to evaluate patient satisfaction. Surveys are randomly mailed out to families seen in our clinic by the survey vendor, and the results are determined on a quarterly basis. We distributed the same survey in a similar manner in our clinic. The results of the surveys, external/mailed (EXM) versus internal/point of care (INP) over the same 3-month time period (second quarter 2013) were compared. The survey questions are dichotomized from an ordinal scale into either excellent (9 to 10) or not excellent (0 to 8) commonly used in patient satisfaction methodology. We evaluated the raw data from the INP surveys for the question on provider rating by evaluating the mean score, the standard excellent response (9 to 10), and an expanded excellent response (8 to 10). RESULTS: Response rate was 72/469 (15.4%) for EXM, and 231/333 (69.4%) for INP. An excellent response for the "rating your provider" question was 72.2% (EXM) versus 84.8% (INP) (P=0.015). Our analysis of the raw data (INP) has a mean rating of 9.42. The expanded scale (8 to 10) for an excellent response increased the provider rating to 94.4% (P=0.001). Waiting time response within 15 minutes was the only item that correlated with rating of provider (P=0.02). For the majority of the items, the INP responses were consistently higher than the EXM responses, including 6/7 responses that were statistically significant (P<0.05). CONCLUSIONS: As mandated by the Centers for Medicare and Medicaid Services, patient satisfaction surveys will be important in determining health care outcomes. Properly designed and administered surveys provide robust measures of quality. Our study reinforces methodological concerns about patient satisfaction surveys distributed in a high-volume pediatric subspecialty practice. Further research is needed to evaluate the patients' health care experience and true quality of care in pediatric subspecialty ambulatory settings.

Evaluation and treatment of developmental hip dysplasia in the newborn and infant.

Developmental dysplasia of the hip (DDH) encompasses a spectrum of physical and imaging findings. The child's hip will not develop normally if it remains unstable and anatomically abnormal by walking age. Therefore, careful physical examination of all infants to diagnosis and treat significant DDH is critical to provide the best possible functional outcome. Regardless of the practice setting, all health professionals who care for newborns and infants should be trained to evaluate the infant hip for instability and to provide appropriate and early conservative treatment or referral.

Diagnosis and initial management of musculoskeletal coccidioidomycosis in children.

BACKGROUND: Coccidioidomycosis is an invasive fungal infection caused by the inhalation of aerosolized spores of Coccidioides spp., which reside in the arid soil of the southwestern United States and northern Mexico. Approximately two thirds of cases are asymptomatic, and the remainder usually present with mild flu-like symptoms. Dissemination of coccidioidomycosis is rare, and can lead to extrapulmonic diseases including meningitis, osteomyelitis, and skin and soft-tissue involvement. The purpose of this study is to report our experience with musculoskeletal coccidioidomycosis in children. METHODS: This was a retrospective chart review of patients with musculoskeletal infection with Coccidioides spp. at a tertiary care pediatric hospital from 1997 to 2010, identified by a search of ICD-9 codes and hospital diagnoses. Demographic and clinical data were collected from medical records, including the age of the patient, sex, white blood cell count, immunocompetence, length of stay, location of involvement, and initial treatment. In total, 20 children were identified with musculoskeletal coccidioidomycosis. The mean age was 12.3 years (range, 2 to 17 y) at time of diagnosis. Diagnostic criteria included positive imaging tests (plain film+MRI), serologic positive titers, and/or biopsy with positive cultures. RESULTS: The most common presenting symptom was bone pain (100%); only 3 (15%) patients had accompanying signs/symptoms of pulmonary infection. Only 2 (5%) patients had a white blood cell count >15×10/L (5%). Locations of infection included the foot (28%), knee (14%), spine (12%), forearm (10%), lower leg (6%), and other sites (30%). Fluconazole was the most common antifungal agent used (75%). Surgical intervention was required in 10 (50%) patients. CONCLUSIONS: This is the first series that has described musculoskeletal coccidioidomycosis exclusively in children. This study suggests that the initial presentation of this disease can be nonspecific and difficult to recognize in children. Clinicians should consider this diagnosis when faced with a musculoskeletal infection in children from the southwestern United States and northern Mexico. LEVEL OF EVIDENCE: IV (case series).

Are We Undermedicating Patients With Neuromuscular Scoliosis After Posterior Spinal Fusion?

STUDY DESIGN: Retrospective, matched study of patients with adolescent idiopathic scoliosis (AIS) and patients with cerebral palsy (CP) undergoing (PSF). OBJECTIVES: To compare pain management, through measurement of the amount of narcotic used and pain scores, for patients with neuromuscular (NM) scoliosis undergoing PSF to a cohort of patients with AIS. SUMMARY OF BACKGROUND DATA: Posterior spinal fusion for children with severe NM scoliosis carries a high risk of complications. Appropriate assessment of pain is crucial; undertreatment of pain leads to anxiety whereas overtreatment can lead to respiratory depression and additional complications. METHODS: A series of patients with NM scoliosis was matched for age, gender, and weight with a group of patients with AIS. Data collection included age, curve type and magnitude, and instrumentation type and levels fused. The total opioid used (TOU) was determined by summing all narcotics given during the hospital stay and converting them to morphine equivalent units. The data were then analyzed to determine differences in TOU. RESULTS: A total of 25 patients with NM scoliosis were included in the study. This group was matched with 25 patients with AIS scoliosis. The TOU for the NM group was 1.2 mg morphine/kg (range, 0.28-4.21 mg morphine/kg) whereas the TOU for the AIS group was 3.52 mg morphine/kg (range, 0.71-15.51 mg morphine/kg) (p < .0000001). CONCLUSIONS: In this case-control analysis, patients with AIS undergoing PSF received more than twice the amount of narcotic compared with a matched group of patients with NM scoliosis. These data suggest that NM patients' pain may be undertreated compared with AIS patients. More study is indicated to investigate pain assessment and pain control in this vulnerable patient population to improve care.

Evaluation of a Novel Method for Determining Transverse Plane Pelvic Obliquity.

STUDY DESIGN: This was a retrospective review of neuromuscular scoliosis radiographs evaluating interobserver and intra-observer error for a novel method of transverse plane pelvic obliquity. OBJECTIVES: To evaluate the utility of a previously described method by Lucas et al. of determining transverse plane pelvic obliquity using standard radiographs in patients with cerebral palsy and neuromuscular scoliosis. SUMMARY OF BACKGROUND DATA: Evaluation of pelvic obliquity in the transverse plane has not been thoroughly studied. The pelvis has been noted to function as intercalary vertebra in neuromuscular scoliosis, resulting in marked obliquity in all 3 planes. METHODS: Forty radiographs were chosen from 10 patients with cerebral palsy and neuromuscular scoliosis who had had a posterior spine arthrodesis and Galveston spino-pelvic fixation. Four observers independently examined the radiographs at different levels of training on 2 dates 1 week apart. Measurements recorded by each observer were described by Lucas et al.: E (the distance measured on lateral radiographs between the ilium at the inferior part of the sacro-iliac joint and the lateral edge of the anterior superior iliac spine), FR and FL (the coronal plane linear distance between the same 2 landmarks, measured from a posteroanterior radiograph, where F was measured for both the left (FL) and right (FR) sides of the pelvis, respectively), and ß (the transverse plane rotation of the pelvis). Reproducibility of the measurements were analyzed using the concordance correlation coefficient (CCC). A CCC of 0.80 or higher was considered excellent agreement. RESULTS: The CCC between the first and second sets of measurements was lowest for E and highest for the calculated ß, although none of the CCC calculations was statistically significant, demonstrating poor agreement. CONCLUSIONS: The ability to reliably measure and calculate the degree of transverse plane rotation by radiographs in cerebral palsy patients with spino-pelvic deformity by the method described by Lucas et al. is poor, likely because of difficulty in consistently identify pelvic landmarks.

Independent analysis of a clinical predictive algorithm to identify methicillin-resistant Staphylococcus aureus osteomyelitis in children.

BACKGROUND: The number of serious, life-threatening musculoskeletal infections in children due to methicillin-resistant Staphylococcus aureus (MRSA) infections is increasing. The early identification of the bacteria causing osteomyelitis is critical to determine the appropriate antibiotic treatment. A recent study proposed a clinical algorithm to predict which infections were caused by MRSA by stratifying basic clinical values at the time of admission for children with osteomyelitis. The purpose of this study is to apply that predictive algorithm on an independent patient population to determine its wider applicability. METHODS: This was a retrospective chart review at a tertiary care children's hospital. All children who were treated for a culture-positive osteomyelitis were identified over a 3-year period. The previously reported predictors, determined by multivariate regression analysis, of MRSA infection (temperature >38°C, hematocrit <34%, white blood cell count >12,000/µL, and C-reactive protein >13 mg/L) were determined for each patient. The number of positive predictors was then correlated with the percentage of cases that were MRSA positive. RESULTS: A total of 58 patients with culture-positive osteomyelitis were identified from 2008 to 2010. Sixteen of the infections were caused by MRSA (overall 26%). The percentage of patients with MRSA osteomyelitis according to the number of risk factors were as follows: all 4 risk factors, 50% (1 out of 2 patients); 3 risk factors, 42% (5 out of 12 patients); 2 risk factors, 21% (4 out of 19 patients); 1 risk factor, 50% (6 out of 12 patients); and 0 risk factor, 0% (0 out of 13 patients). CONCLUSIONS: The previously reported clinical predictive algorithm had a relatively poor diagnostic performance in this independent patient population. Specifically, the percentages of MRSA were the same for 1 risk factor compared with 4 (50%). Differences in bacteria strain, host responses, and a variety of other confounding variables could be responsible for these differences. Specific genetic markers may be the best early test to identify MRSA infections in the future. LEVEL OF EVIDENCE: Level III-case-control series.

Missed fractures in paediatric trauma patients.

Missed fractures and other occult musculoskeletal injuries are common in paediatric trauma patients despite the thorough evaluation with standard trauma protocols. Several factors have been identified that contribute to the risk of failing to identify these injuries during the initial resuscitation and assessment of the paediatric trauma patient. These include patient-related, clinical, technical, and radiological causes. Preventive strategies have been proposed to minimize these overlooked injuries and their potential long-term consequences. A timely review of this problem is appropriate to continually improve the quality of care delivered to paediatric trauma patients.

The spectrum of musculoskeletal problems in lipomyelomeningocele.

PURPOSE: Patients with lipomyelomeningocele (LMMC) represent a unique population within the spectrum of spinal dysraphism. The natural history of LMMC remains poorly defined. The description and prevalence of the presenting orthopaedic clinical signs and symptoms for LMMC have been infrequent and often documented only in general terms. The goal of this study is to define the patterns and prevalence of presenting clinical musculoskeletal signs and symptoms in LMMC patients. METHODS: This study was a retrospective review of charts of all patients identified as having LMMC in our spina bifida clinic. Patient charts with incomplete data or diagnoses other than LMMC were excluded from the analysis. Data collected included age at initial tethered cord release (TCR); repeat TCR; limb length discrepancy; foot deformities; asymmetry of motor and sensory deficits; presence of scoliosis; orthotic needs; assistive devices; functional status. RESULTS: We identified 32 patients with LMMC (21 female and 11 male patients). The majority of patients had their primary TCR by ≤1 year of age (59 %), with 22 and 19 % having primary TCR at ages 1-15 and >15 years, respectively. Fifteen patients had at least one repeat TCR, with ten of these having more than one repeat TCR. A significant relationship was noted between low back/radicular pain and repeat TCR (p < 0.001). Ten patients (31%) had a limb length discrepancy of >2.5 cm, and 53 % of patients had asymmetric involvement. Nine patients (28 %) had scoliosis of whom only one required operative treatment. Fifteen patients had foot deformities. Thirteen patients (41 %) had two or more orthopaedic procedures in addition to other neurologic or urologic procedures. CONCLUSION: The presenting musculoskeletal clinical signs and symptoms in patients with LMMC are uniquely different in terms of both pattern and frequency compared to myelomeningocele and other forms of spinal dysraphism. We noted a high prevalence of asymmetrical involvement, a high operative burden, and a high rate of repeat symptomatic tethered cord syndrome requiring TCR. As previously noted by others, TCR in LMMC does not prevent long-term functional deterioration. These findings may be important to our colleagues providing counsel to their patients with LMMC and to their families.

Pulmonary embolism following an ankle fracture in a 9-year-old boy: a case report.

Venous thromboembolism following trauma is an uncommon event in childhood and associated pulmonary embolus after routine lower extremity fracture is exceedingly rare. We present a case report of postoperative pulmonary embolus following an open reduction and internal fixation of a Salter-Harris IV medial malleolus fracture in a 9-year-old boy. Four days after open reduction and percutaneous pin fixation of the ankle fracture, the child began to experience chest pain and shortness of breath. Computed tomographic angiography demonstrated a pulmonary embolus, and he was started on anticoagulation therapy. The child had no medical history, family history, nor known risk factors for venous thromboembolism other than the fracture, and a thrombophilic work-up revealed no coagulopathies or other blood disorders. He was treated with Coumadin for three months. His orthopedic course was uneventful; the fracture healed and he returned to normal function. This appears to be the first case reported in the literature of a significant pulmonary embolus after a routine ankle fracture in a child. While insufficient to warrant deep venous thrombosis prophylaxis in all children, this case report suggests that a venous thromboembolic event can occur even in uncomplicated fractures in children.

Periosteal entrapment in distal femoral physeal fractures: harbinger for premature physeal arrest ?

We report on two patients who sustained Salter-Harris II fractures of the distal femur with physeal widening after being tackled in football games. Preoperative MRI indicated entrapped periosteum at the physeal fracture site for both patients. Both patients underwent open reduction of the physeal fracture with removal of the entrapped periosteum and achieving an anatomic reduction. Follow-up MRI's revealed premature physeal arrest. Subsequent procedures were performed to address sequelae of premature physeal arrest. The presence of physeal widening and entrapped periosteum may reflect high-energy trauma to the physis. This can result in injury to both the epiphyseal blood supply and to the physeal cartilage (germinal zone) resulting in physeal arrest despite anatomic reduction after removal of the entrapped periosteum. Upon literature review, pre-operative MRI demonstrating entrapped periosteum has not been previously reported. We hypothesize that the presence of entrapped periosteum following distal femoral physeal fractures may be associated with an increased risk for premature physeal arrest.

Bedside ultrasound in the diagnosis of pediatric clavicle fractures.

OBJECTIVE: The objective of the study was to determine the diagnostic accuracy of pediatric emergency physicians in diagnosing clavicle fractures by bedside ultrasound (US). METHODS: This was a prospective study of pediatric emergency department (ED) patients with suspected clavicle fractures conducted in a tertiary-care, freestanding pediatric hospital. A convenience sample of patients younger than 17 years underwent bedside US for detection of clavicle fracture by pediatric emergency physicians with limited US training. Ultrasound findings were compared with standard radiographs, which were considered the criterion standard. Pain scores using the validated color analog scale (0-10) were determined before and during US. Total length of stay in the ED, time to US, and time to radiograph were recorded. RESULTS: Fifty-eight patients were enrolled, of which 39 (67%) had fracture determined by radiograph. Ultrasound interpretation gave a sensitivity of 89.7% (95% confidence interval [CI], 75.8%-97.1%) and specificity of 89.5% (95% CI, 66.9%-98.7%). Positive and negative predictive values were 94.6% (95% CI, 81.8%-99.3%) and 81.0% (95% CI, 58.1%-94.5%), respectively. Positive and negative likelihood ratios were 8.33 and 0.11, respectively. Pain scores averaged 4.7 before US and 5.2 during US (P = 0.204). There was a statistically significant difference between mean time to US (76 minutes) and mean time to radiograph (107 minutes) (P < 0.001). CONCLUSIONS: Pediatric emergency physicians with minimal formal training can accurately diagnose clavicle fractures by US. In addition, US itself is not associated with an increase in pain and may reduce length of stay in the ED.

Suspected nonaccidental trauma and femoral shaft fractures in children.

The question of suspected nonaccidental trauma as a possible cause of injury for femoral shaft fractures in children is a troubling but common issue facing orthopedic surgeons. The purpose of this study is to analyze femoral shaft fractures at a major pediatric level I trauma center in a large metropolitan area over a 5-year period to determine the incidence of suspected nonaccidental trauma and the risk factors associated with that diagnosis. This study is a retrospective review of all children younger than 5 years at a large trauma center in a southwestern metropolitan area who presented with a femoral shaft fracture. Patient charts were reviewed to determine demographics, mechanism of injury, and fracture type. Referrals to social work and Child Protective Services were also reviewed to determine an overall incidence of suspected nonaccidental trauma.Over the 5-year study period, 137 patients presented to our institution with a femoral shaft fracture. Mean patient age at the time of injury was 2.2 years (range, 1 month to 4 years). Overall, 43 patients with a mean age of 1.8 years were determined to have injuries suspicious of nonaccidental trauma and were referred to Child Protective Services, giving an overall incidence of 31%. Age younger than 1 year was a highly significant risk factor for suspected nonaccidental trauma. Of the 20 children younger than 1 year, 18 (90%) were referred to Child Protective Services, comprising 42% of those children suspicious of nonaccidental trauma. The presence of either Medicaid or no insurance was a highly statistically significant risk factor for suspected nonaccidental trauma.
