Shipley J, Grigorian A, Emigh B, Dilday J, Kuza C, Schubl S, Swentek L, Brown N, Nahmias J. Is Adolescent Obesity Associated With a Higher Risk for Pelvic Fractures in Motor Vehicle Collisions? J Surg Res 2024; 295:261-267. [PMID: 38048749 DOI: 10.1016/j.jss.2023.11.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2023] [Revised: 09/21/2023] [Accepted: 11/08/2023] [Indexed: 12/06/2023]
Abstract
INTRODUCTION The impact of obesity on the incidence of blunt pelvic fractures in adults is unclear, and adolescents may have an increased risk of fracture due to variable bone mineral density and leptin levels. Increased subcutaneous adipose tissue may provide protection, though the association between obesity and pelvic fractures in adolescents has not been studied. This study hypothesized that obese adolescents (OAs) presenting after motor vehicle collision (MVC) have a higher rate of pelvic fractures, and OAs with such fractures have a higher associated risk of complications and mortality compared to non-OAs. METHODS The 2017-2019 Trauma Quality Improvement Program database was queried for adolescents (12-16 y old) presenting after MVC. The primary outcome was a pelvic fracture. Adolescents with a body mass index ≥30 (OA) were compared to adolescents with a body mass index <30 (non-OA). Subgroup analyses for high-risk and low-risk MVCs were performed. Multivariable logistic regression analyses were also performed adjusting for age and sex. RESULTS From 22,610 MVCs, 3325 (14.7%) included OAs. The observed rate of pelvic fracture was similar between all OA and non-OA MVCs (10.2% versus 9.4%, P = 0.16), as well as subanalyses of minor or high-risk MVC (both P > 0.05). OAs presenting with a pelvic fracture after high-risk MVC had a similar risk of complications, pelvic surgery, and mortality compared to non-OAs (all P > 0.05). However, OAs with a pelvic fracture after minor MVC had a higher associated risk of complications (OR 2.27, CI 1.10-4.69, P = 0.03), but a similar risk of requiring pelvic surgery, and mortality (all P > 0.05). CONCLUSIONS This national analysis found a similar observed incidence of pelvic fractures for OAs versus non-OAs involved in an MVC, including subanalyses of minor and high-risk MVC. Furthermore, there was no difference in the associated risk of morbidity and mortality except for OAs involved in a minor MVC had a higher risk of complication.

Abstract
Pediatric obesity is a global concern with distressing comorbid conditions, including mood disturbance, cardiovascular changes, endocrine imbalance, liver disease, sleep apnea, and orthopedic conditions. The primary treatment of this condition includes physical activity. Participating in organized sports has been shown to reduce weight and the complications of pediatric obesity more effectively than individual exercise.

Abstract
Currently the gold standard in surgical treatment of displaced tibial shaft fractures in children with open growth cartilage is elastic stable intramedullary nailing (ESIN). The purpose of this study is the analysis of indications, complications, and duration of treatment using intramedullary flexible nails in children who are still growing but especially weighing 50 kg or more. Hospital records from 2017 to 2020 were retrospectively reviewed to identify the children from 4 to 17 years of age with displaced tibial shaft fractures admitted to the hospital. Only children with open growth cartilage, with a minimum of 6 months of follow-up and complete clinical data, were included. Studies of 91 children xwere analyzed. The average patient age at the time of the injury was 10.88 ± 2.82 years. In the entire group, 31.9% children weighed 50 kg or more, and 68.1% of the children were below this weight. All children were treated using ESIN. The mean time to nail removal was 8.4 ± 4.09 months in the whole group of children stabilized with ESIN. There were no differences in the two groups depending on the weight ( P = 0.637). Only two adverse events were observed. This study demonstrates that the use of ESIN in displaced tibial shaft fractures in growing children weighing 50 kg or more is acceptable and safe. The discussion to be made is whether it is still an acceptable method of treatment for this type of fracture due to the progressive obesity epidemic in children and adolescents.

Abstract
The current childhood obesity epidemic, affecting approximately 20% of American children and adolescents, is accompanied by unique orthopedic manifestations. The growing musculoskeletal system is susceptible to the endocrine effects of obesity, resulting in decreased bone mass and quality. As a result, obese children are at increased risk of musculoskeletal injury, fracture, and lower extremity deformities. The efficacy of nonoperative treatment such as casting or bracing may be limited by body habitus and surgical treatment is accompanied by increased risk of perioperative complications.

Factors associated with conversion to open reduction of type 3 supracondylar humerus fractures in children. J Clin Orthop Trauma 2022; 30:101893. [PMID: 35668919 PMCID: PMC9163578 DOI: 10.1016/j.jcot.2022.101893] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 04/19/2022] [Accepted: 05/06/2022] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND The US News and World report utilizes the number of supracondylar humerus fractures treated in an open procedure, excluding open fractures and vascular exploration, as a metric in assessing Pediatric Orthopedic trauma care. The purpose of this study was to identify factors that increase the likelihood of a patient needing open reduction for Gartland Type 3 SCH fractures. METHODS All pediatric patients who underwent surgical management of closed, Type 3 SCH fractures at our Pediatric Level 1 Trauma Center between 2011 and 2017 were considered for inclusion. Patient age greater than 16 years, patients with closed physes and open fractures were excluded. Electronic medical records and radiographic imaging were reviewed. Student's t- and chi-squared tests were used, and logistic regression was performed comparing closed v open reduction. RESULTS 362 subjects were included in this study. 318/362 (87.8%) were treated with closed reduction. 44/362 (12.2%) required open reduction. There were no statistically significant differences in age, gender, BMI, concomitant ipsilateral extremity fractures, Type 4 unstable fracture or patients that underwent hospital transfer. The mechanisms of injury with the greatest percentage requiring open reduction were fall from furniture and trampoline. Of those patients that underwent open reduction, 65.9% had posterolateral displacement of the fracture. Those with displacement >4 mm had 3.14 higher odds of requiring an open reduction (p = 0.002). The anterior spike fracture pattern had the highest rate of failed closed reduction of 66.7%. Of those patients that had an open reduction, 13/44 (29.5%) had a neuropraxia and 5/44 (11.4%) had vascular compromise. Those with neuropraxia had 3.26 higher odds of requiring an open reduction (p = 0.005). Time to operating room was significantly shorter in patients that underwent open reduction (p < 0.001). CONCLUSION Our rate of open reduction for Type 3 SCH fractures, 12.2%, is consistent with previously described rates. Posterolateral displacement of fractures, displacement >4 mm, fractures with an anterior spike and fractures associated with neurovascular compromise are more likely to undergo open reduction. Transfer status, BMI and patient age were not associated with open reduction. Open reduction was associated with shorter time to the operating room, likely representing the urgent care of significantly displaced fractures associated with neurovascular compromise.

Abstract
BACKGROUND Obesity is a growing global health problem and a well-recognized risk factor for many medical conditions. This meta-analysis was conducted to assess the effect of obesity on overall complication occurrence, mortality, and hospital length of stay in patients with nonpathological lower limb trauma. METHODS The EMBASE, PUBMED, and MEDLINE electronic databases were searched from inception to April 1, 2020, for studies published in English. References cited by chosen studies were also checked manually for inclusion. Studies chosen for the analysis were prospective observational or retrospective cohort studies reporting on total complications of patients with acute traumatic, nonpathological, lower limb fractures that required internal fixation, with or without other underlying conditions. Two investigators independently reviewed the full text of eligible studies for inclusion and extracted data. Inconsistency was resolved through consultation with other authors. RESULTS Sixteen studies with 404,414 patients were investigated in this study. The data showed obesity was related with increased total complications (odds ratio [OR], 0.65; 95% confidence interval [CI], 0.51-0.83; p < 0.01), increased wound complications (OR, 0.41; 95% CI, 0.25-0.66; p < 0.01), and increased mortality rate (OR, 0.64; 95% CI, 0.45-0.91; p < 0.05). Six cohort studies also showed prolonged hospital length of stay in obese patients. CONCLUSION Our results suggest that obesity is associated with increased complication and mortality rates, as well as longer hospital length of stay in patients with lower-limb trauma who required surgical treatment. These findings may raise attention to optimize surgical technique and develop individualized treatment for obese patients. LEVEL OF EVIDENCE Systematic reviews, level IV.

Abstract
Queries of youth orthopedic sports injuries from the U.S. National Electronic Surveillance System, a database from the Consumer Product Safety Commission, demonstrate decreased orthopedic injuries related to team sports during the COVID-19 pandemic, indicative of reduced sports participation. Multiple articles have shown that COVID-19 had a marked effect on the physical and psychological wellbeing of the youth. The lockdown resulted in a cessation in school attendance and sports activities, especially team sports. Though increased emphasis has been placed on children infected by COVID-19, less attention has been given to healthy children. Numerous articles discussed the physical and psychological benefits for the youth returning to physical activity and sports; however, few have addressed detraining and deconditioning concerns postpandemic. This article discusses a safe return to team sports for the youth experiencing physical and psychological changes related to the pandemic. Orthopedic injuries are anticipated to increase as restrictions are relaxed. A multidisciplinary team presents a review of common youth sports orthopedic injuries, a discussion of psychological issues youths have experienced during COVID and why sports participation is beneficial for youth, and a risk assessment for pain and limited range of motion for youth returning to sports. The intent of this article is to increase awareness of the physical and psychological changes experienced by youth due to their inability to participate in team sports during the pandemic. Family medicine and primary care providers need to recognize the increased risks for injury and proactively encourage the youth to return to sports in a safe manner.

Abstract
BACKGROUND The medical community has recognized overweight as an epidemic negatively affecting a large proportion of the pediatric population, but few studies have been performed to investigate the relationship between overweight and failure of conservative treatment for distal radius fractures (DRFs). This study was performed to investigate the effect of overweight on the outcome of conservative treatment for DRFs in children. METHODS We performed a retrospective study of children with closed displaced distal metaphyseal radius fractures in our hospital from January 2015 to May 2020. Closed reduction was initially performed; if closed reduction failed, surgical treatment was performed. Patients were followed up regularly after treatment, and redisplacement was diagnosed on the basis of imaging findings. Potential risk factors for redisplacement were collected and analyzed. RESULTS In total, 142 children were included in this study. The final reduction procedure failed in 21 patients, all of whom finally underwent surgical treatment. The incidences of failed final reduction and fair reduction were significantly higher in the overweight/obesity group than in the normal-weight group (P = 0.046 and P = 0.041, respectively). During follow-up, 32 (26.4%) patients developed redisplacement after closed reduction and cast immobilization. The three risk factors associated with the incidence of redisplacement were overweight/obesity [odds ratio (OR), 2.149; 95% confidence interval (CI), 1.320-3.498], an associated ulnar fracture (OR, 2.127; 95% CI, 1.169-3.870), and a three-point index of ≥ 0.40 (OR, 3.272; 95% CI, 1.975-5.421). CONCLUSIONS Overweight increases the risk of reduction failure and decreases the reduction effect. Overweight children were two times more likely to develop redisplacement than normal-weight children in the present study. Thus, overweight children may benefit from stricter clinical follow-up and perhaps a lower threshold for surgical intervention.

Abstract
BACKGROUND There is currently a debate about whether elastic stable intramedullary nails (ESIN) or external fixation (EF) is the best surgical method for treating pediatric femoral shaft fractures. We performed a meta-analysis to determine which surgical method leads to higher treatment satisfaction, lower complication rates, and reduced treatment time, to investigate whether ESIN is the preferred surgical method for treatment of pediatric femoral shaft fractures. PATIENTS AND METHODS Relevant databases were searched for comparative studies of ESIN versus EF for the treating pediatric femoral shaft fractures. Literature reports and quality evaluations were extracted, followed by a systematic review using RevMan 5.3 software. Treatment satisfaction at the last follow-up, primary complications, secondary complications, and relevant time indicators (operation time, hospital stay, clinical healing time, bone healing time) were analyzed. RESULTS A total of 22 reports were included in this meta-analysis. We found no statistical differences in the treatment satisfaction at the last follow-up between ESIN and EF for the treatment of pediatric femoral shaft fractures. A low rate of postoperative re-fracture (RR=3.58, 95% CI (1.85, 6.92), p=0.0001) and postoperative infection (RR=9.25, 95% CI (5.32, 16.11), p<0.00001), and a high risk of skin irritation (RR=0.15, 95% CI (0.06, 0.37), p<0.00001) were found in the ESIN group. No significant differences between the two approaches were found regarding malunion. A low rate of limb-length discrepancy (RR=2.41, 95% CI (1.40, 4.17), p=0.002), hospitalization (SMD=0.84, 95% CI (0.24, 1.43), p=0.006), clinical healing time (SMD=0.95, 95% CI (0.56, 1.33), p<0.00001) and bone healing time (SMD=0.89, 95% CI (0.39, 1.40), p=0.005) were found in the ESIN group, as compared to that in the EF group. No significant differences were found in fixation failure, activity limitation of the joint, and operation time between the two strategies. DISCUSSION ESIN should be the primary choice for the treatment of pediatric femoral shaft fractures since it has a reliable curative effect and results in a shorter hospital stay, faster fracture healing, and fewer complications. EF is recommended for fractures with serious injury of the soft tissue to avoid intramedullary infection. Double-blind high-quality randomized studies with larger sample sizes are warranted to confirm our conclusions. LEVEL OF EVIDENCE IV.

Abstract
Pediatric obesity has become a worldwide epidemic and leads to notable effects on the developing skeleton that can have lifelong implications. Obesity in the pediatric population alters bone metabolism, increasing the risk for fracture. It can alter the presentation of common pediatric orthopaedic conditions such as scoliosis. Obesity also leads to changes in the patterns and severity of pediatric fractures as well as alters conservative fracture treatment due to increased displacement risk. Obese pediatric trauma patients place a high burden on the nationwide hospital system in a variety of ways including the increased risk of perioperative complications. Obesity is modifiable, and addressing the issue can improve the orthopaedic and overall health of children.

Abstract
The main objective of this paper is to review the current literature on treatment of tibial and femur fractures in children and adolescents guided by body weight in patients weighing 50 kg (110 lb) or more. A secondary aim of this mini-review was to determine, as per literature review, whether weight > 50 kg (110 lb) is an identifiable factor associated with increased complication rate. A search of the PubMed/MEDLINE, EMBASE and Cochrane Database of Systematic Reviews databases from 1954 to September 2017 was performed to identify papers related to pediatric tibia and femur fractures in children weighing more than 50 kg (110 lb). Abstracts were screened, and relevant full-text articles were retrieved for further review. Reference sections of identified papers were also screened to identify further literature. All levels of evidence were included. Overall, seven full-text articles dealing with pediatric tibia or femur fractures in patients weighing more than 50 kg (110 lb), and one article reporting on both femur and tibia fractures in this patients' population, have been identified (n = 8 full-text article included). The articles reviewed a total of 679 children. In particular, 48/438 femur shaft fractures (mean weight: 51.7 kg or 113.9 lb) and 91/241 tibia fractures (mean weight: 53.3 kg or 117.5 lb) met the inclusion criteria. The overall rate of complications was 27.9%. In particular, the rate of complication was 51.7 and 29.6% in children with femur and tibia fracture weighing more than 50 kg (110 lb), respectively (p < 0.05). Elastic stable intramedullary nailing (ESIN) has become the treatment of choice for displaced tibia and femur shaft fractures in children between six and 12-15 years of age. Unstable fracture pattern, higher age and higher weight have been reported as potential risk factors associated with poor outcomes in children and adolescents treated with ESIN for displaced long bone fractures of the lower extremity, in particular femur shaft fractures. Despite these findings, data reporting exclusively on ESIN-treated long bone fractures in children weighing 50 kg (110 lb) or more remain scant.

Abstract
INTRODUCTION The insertion of 2 elastic stable intramedullary nails (ESINs) is a common treatment for pediatric femur fractures. However, the use of this technique in length-unstable or metadiaphyseal fractures has historically been associated with higher complication rates. To improve stability, the addition of a third ESIN has been assessed biomechanically and clinically, but the addition of a fourth nail has only been evaluated biomechanically. The purpose of this study is to report our surgical technique and radiographic outcomes using a quartet of ESINs in pediatric femur fractures. METHODS A retrospective review was performed of pediatric patients with length-unstable or metadiaphyseal femur fractures who were treated with 4 ESINs by a single surgeon from 2008 to 2013. Nails were inserted in a retrograde manner, 2 each from medial and lateral starting points. Patients were followed clinically and radiographically until the union and routine removal of hardware. Primary outcomes included fracture union, sagittal, and coronal plane alignment, and complications. RESULTS Fourteen patients underwent quartet ESIN placement. Two patients were excluded: one for early loss to follow-up and another with a diagnosis of osteogenesis imperfecta. The average patient age was 9.3 years (range, 4 to 14 y) and weight was 47 kg (range, 21 to 95 kg). All fractures achieved radiographic union at mean 5.5 months (range, 2 to 9 mo). Hardware was removed at a mean of 9.4 months (range, 2 to 22 mo) following implantation. At final mean follow-up of 18 months, patients and families reported no functional limitations. There were no hardware failures or revision surgeries. There were no limb length discrepancies or malalignment at the time of final radiographic follow-up. There were 2 minor complications-1 patient with pain secondary to nail migration resulting in prominence at the knee and another with refracture following a fall. The stable refracture occurred before complete fracture union and hardware removal and went on to the union without the need for any additional treatment. CONCLUSIONS Treatment with a quartet of ESINs should be considered for skeletally immature children with length-unstable or metadiaphyseal femur fractures. In this series, all fractures achieved union without major complications or hardware failure. This modification to traditional elastic nailing techniques is an option for the surgeon to consider as an alternative to rigid intramedullary nailing, submuscular plating, or external fixation.

Abstract
The Italian Consensus Position Statement on Diagnosis, Treatment and Prevention of Obesity in Children and Adolescents integrates and updates the previous guidelines to deliver an evidence based approach to the disease. The following areas were reviewed: (1) obesity definition and causes of secondary obesity; (2) physical and psychosocial comorbidities; (3) treatment and care settings; (4) prevention.The main novelties deriving from the Italian experience lie in the definition, screening of the cardiometabolic and hepatic risk factors and the endorsement of a staged approach to treatment. The evidence based efficacy of behavioral intervention versus pharmacological or surgical treatments is reported. Lastly, the prevention by promoting healthful diet, physical activity, sleep pattern, and environment is strongly recommended since the intrauterine phase.

Abstract
BACKGROUND As childhood obesity remains an ongoing issue for the United States there has been an increasing number of studies detailing its effect on fracture complexity, management, and outcomes. This study utilizes a national database to examine whether obese children with supracondylar humerus fractures are more likely to require open reduction and internal fixation than nonobese children. METHODS The Healthcare Cost and Utilization Project Kid's Inpatient Database of 2003, 2006, 2009, 2012 were queried for pediatric supracondylar humerus fractures [International Classification of Disease (ICD-9), 812.41] between 2 and 12 years. Patients were separated into those undergoing closed reduction percutaneous pinning (CRPP), open reduction internal fixation (ORIF), or both. Obesity was determined by comorbidity and ICD-9 coding (ICD-9, 278.00, 278.01). Univariable and multivariable logistic regression models were utilized with P<0.05 considered significant. RESULTS Between 2003 and 2012, 31,905 patients between the ages of 2 and 12 years sustained supracondylar humerus fractures. In total, 105 patients (0.3%) were obese. A majority of patients, 27,658 (86.7%), underwent CRPP. Odds for ORIF increased in association with age, obesity, white race, and private insurance. Significant association was found between age and obesity (P<0.05) in those undergoing ORIF. Obese children between 2 and 7 years of age had no difference in ORIF or CRPP compared with normal-weight children. Those between 8 and 12 years who were obese were significantly more likely to undergo ORIF (OR, 4.29; 95% confidence interval, 1.78-10.36). CONCLUSIONS Supracondylar humerus fractures sustained in obese children between 8 and 12 years are over 4 times more likely to require ORIF compared with normal-weight children of the same age. Providers should identify and counsel older obese children and their families regarding the potential for increased difficulty in fracture management that may require open surgical intervention.

Abstract
OBJECTIVES To determine if high body mass index (BMI) increases the risk of loss of reduction (LOR) following closed reduction and casting for displaced concomitant fractures of the radial and ulnar shafts in pediatric patients. DESIGN Retrospective cohort study. SETTING A single, tertiary care, urban children's hospital. PATIENTS/PARTICIPANTS Pediatric patients 2-18 years of age with closed, displaced, concomitant diaphyseal fractures of the radius and ulna (OTA/AO 22-A3) who underwent closed reduction and casting at the study site. MAIN OUTCOME MEASURES BMI percentile of ≥95 was defined as obese. For nonobese patients, BMI percentile of ≥85 was defined as overweight. BMI percentile category, fracture angulation, sex, age, fracture location, and number of follow-up visits were recorded. Radiographs and health records were reviewed to note clinical and radiographic cases of LOR. The primary outcome was LOR (clinical or radiographic). RESULTS Overall, 124 subjects (74 male and 50 female subjects) underwent acceptable closed reduction and casting. Median patient age was 7.6 years (range, 2.2-17.8 years). There were 14 cases of LOR. LOR rates were 7.2%, 16.7%, and 44.4% for the nonoverweight, overweight, and obese cohorts, respectively (P = 0.005). Regression analysis revealed that LOR was positively associated with higher BMI category (odds ratio for overweight 4.49; P = 0.082; odds ratio for obese 7.52; P = 0.020) and patient age in years (odds ratio, 1.38; P = 0.001). CONCLUSIONS Given the high risk of LOR in overweight and obese children with displaced concomitant fractures of the radial and ulnar shafts, our findings suggest that attentive and frequent follow-up is warranted. In these patients, the initial reduction should be closely scrutinized, and a lower threshold for surgical fixation may be considered. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
PURPOSE In pediatric extremity fractures treated nonsurgically, maintaining reduction can be difficult in obese children owing to the larger soft tissue envelope. The purpose of this study was to investigate the relationship between obesity and failure of nonsurgical management of pediatric both-bone forearm fractures. METHODS We conducted a retrospective review of 129 skeletally immature patients older than 2 years who received nonsurgical treatment for closed radius and ulna shaft fractures at a level I pediatric trauma center between 2011 and 2014. The patients were divided into 2 groups: (1) normal-weight children and (2) overweight and obese children. The primary outcome measure was failure of nonsurgical management, defined as the indication for repeat closed reduction under anesthesia or surgical intervention owing to unacceptable angulation after initial closed treatment. RESULTS Of the 129 patients included in the study, 34 patients (26%) were female and 95 patients (74%) were male. Seventy-six patients (59%) were normal weight, 27 patients (22%) were obese, and 26 patients (20%) were overweight. Eighteen percent (14 of 76) of normal-weight children failed nonsurgical management compared with 34% (18 of 53) of overweight and obese children. Twenty-nine percent (4 of 14) of normal-weight children who failed nonsurgical management required surgery compared with 56% (10 of 18) of overweight and obese children. CONCLUSIONS Overweight and obese children have a significantly higher rate of failure of nonsurgical management of both-bone forearm fractures compared with normal-weight children. These patients may benefit from closer clinical follow-up and a lower threshold for surgical intervention. TYPE OF STUDY/LEVEL OF EVIDENCE Prognosis II.

Abstract
BACKGROUND/AIMS Animal studies suggest that leptin may adversely affect bone mineral density (BMD). Clinical studies have yielded conflicting results. We therefore investigated associations between leptin and bone parameters in children. METHODS 830 healthy children (age = 11.4 ± 3.1 years; 75% female; BMI standard deviation score [BMIz] = 1.5 ± 1.1) had fasting serum leptin measured with ELISA and body composition by dual-energy X-ray absorptiometry. The main effects for leptin and BMIz plus leptin's interactions with sex and BMIz were examined using hierarchical linear regressions for appendicular, pelvis, and lumbar spine BMD as well as bone mineral content (BMC), and bone area (BA). RESULTS Accounting for demographic, pubertal development, and anthropometric variables, leptin was negatively and independently associated with lumbar spine BMC and BA, pelvis BA, and leg BA (p < 0.05 for all). Sex, but not BMIz, moderated the associations of leptin with bone parameters. In boys, leptin was negatively correlated with leg and arm BMD, BMC at all bone sites, and BA at the subtotal and lumbar spine (p < 0.01 for all). In girls, leptin was positively correlated with leg and arm BMD (p < 0.05 for both). CONCLUSION Independent of body size, leptin is negatively associated with bone measures; however, these associations are moderated by sex: boys, but not girls, have a negative independent association between leptin and BMD.

Abstract
The purpose of this study was to test a hypothesis that overweight patients with adolescent idiopathic scoliosis present with larger curves and achieve less surgical correction than do healthy weight counterparts. A total of 251 individuals were grouped by BMI into overweight (BMI% ≥85) and healthy weight (BMI% <85) groups. Overweight patients demonstrated significantly larger intraoperative blood loss (P=0.041), although there was no significant difference in the number of intraoperative transfusions. Major curves and surgical correction were similar between the two groups. A greater postoperative thoracic kyphosis at latest follow-up may suggest a worsening sagittal profile in these individuals postoperatively.

Abstract
UNLABELLED Two of the most prevalent problems children facing worldwide are injuries and obesity. We conducted a systematic review of published studies that evaluated the effects of obesity on children with traumatic injuries. Six studies published between 2006 and 2014 were identified, comprising a total of 4594 children: 867 were obese and 3727 were not. Obese children were 25% more likely to have extremity fractures than nonobese children (p = 0.003), and their mortality rate was significantly higher at 4.7% versus 2.8% (p = 0.026). CONCLUSION Our review showed that obese children were more likely to have extremity fractures and die of traumatic injuries than nonobese children.

Abstract
Fetal macrosomia is associated with a 14-fold increased risk of brachial plexus birth palsy (BPBP), and is a predictor of childhood obesity. The purpose of this study was to identify the relationships between BPBP, fetal macrosomia, and childhood obesity. We retrospectively reviewed 214 children with BPBP. The average age was 8 years and 53% had a Narakas 1 grade BPBP. Overall, 49% of children were normal weight, 22% overweight, and 29% obese. Of the children with a history of fetal macrosomia, 41% were obese; a statistically significant difference. Overall quality of life scores, however, were not correlated with obesity.

Abstract
BACKGROUND Elastic stable intramedullary nailing (ESIN) is accepted widely for treatment of diaphyseal femur fractures in children. However, complication rates of 10 to 50 % are described due to shortening or axial deviation, especially in older or heavier children. Biomechanical in vitro testing was performed to determine whether two modified osteosyntheses with end caps or a third nail could significantly improve the stability in comparison to classical elastic stable intramedullary nailing in a transverse femur fracture model. METHODS We performed biomechanical testing in 24 synthetic adolescent femoral bone models (Sawbones®) with a transverse midshaft (diaphyseal) fracture. First, in all models, two nails were inserted in a C-shaped manner (2 × 3.5 mm steel nails, prebent), then eight osteosyntheses were modified by using end caps and another eight by adding a third nail from the antero-lateral (2.5-mm steel, not prebent). Testing was performed in four-point bending, torsion, and shifting under physiological 9° compression. RESULTS The third nail from the lateral showed a significant positive influence on the stiffness in all four-point bendings as well as in internal rotation comparing to the classical 2C configuration: mean values were significantly higher anterior-posterior (1.04 vs. 0.52 Nm/mm, p < 0.001), posterior-anterior (0.85 vs. 0.43 Nm/mm, p < 0.001), lateral-medial (1.26 vs. 0.70 Nm/mm, p < 0.001), and medial-lateral (1.16 vs. 0.76 Nm/mm, p < 0.001) and during internal rotation (0.16 vs. 0.11 Nm/°, p < 0.001). The modification with end caps did not improve the stiffness in any direction. CONCLUSIONS The configuration with a third nail provided a significantly higher stiffness than the classical 2C configuration as well as the modification with end caps in this biomechanical model. This supports the ongoing transfer of the additional third nail into clinical practice to reduce the axial deviation occurring in clinical practice.

Abstract
STUDY DESIGN Original research. OBJECTIVE To evaluate perioperative risk factors associated with obesity in children undergoing posterior spinal fusion for adolescent idiopathic scoliosis. The authors hypothesized that patients with a high body mass index (BMI) percentile would be associated with increased morbidity as measured by various intraoperative parameters. SUMMARY OF BACKGROUND DATA Few studies have evaluated the effects of increased BMI in children undergoing surgery. Adolescent idiopathic scoliosis represents 80% of idiopathic scoliosis cases and is the most common indication for surgery. METHODS Patients were divided into 3 groups: normal weight (n = 144) (5% < BMI < 85%), overweight (n = 25) (BMI > 85% to 95%), and obese (n = 38) (BMI > 95%). Patients with BMI less than 5% were excluded from this study because they were underweight. Perioperative data were collected and analyzed based on differences between groups. RESULTS A total of 207 patients were included in this study. There was a significant difference in the length of anesthesia (p = .032). The rate of infection was 11% in the obese group, 12% in the overweight group, and 3% in the normal weight group (p = .03). CONCLUSIONS Even with pedicle screw instrumentation, the researchers saw an increase in infection in overweight and obese patients. Patients should be counseled before surgery for weight loss to limit surgical complications such as possible risk of postoperative wound infection.

Abstract
BACKGROUND Children and adolescents are at high risk of sustaining fractures during growth. Therefore, epidemiological assessment is crucial for fracture prevention. The AO Comprehensive Injury Automatic Classifier (AO COIAC) was used to evaluate epidemiological data of pediatric long bone fractures in a large cohort. METHODS Data from children and adolescents with long bone fractures sustained between 2009 and 2011, treated at either of two tertiary pediatric surgery hospitals in Switzerland, were retrospectively collected. Fractures were classified according to the AO Pediatric Comprehensive Classification of Long Bone Fractures (PCCF). RESULTS For a total of 2716 patients (60% boys), 2807 accidents with 2840 long bone fractures (59% radius/ulna; 21% humerus; 15% tibia/fibula; 5% femur) were documented. Children's mean age (SD) was 8.2 (4.0) years (6% infants; 26% preschool children; 40% school children; 28% adolescents). Adolescent boys sustained more fractures than girls (p < 0.001). The leading cause of fractures was falls (27%), followed by accidents occurring during leisure activities (25%), at home (14%), on playgrounds (11%), and traffic (11%) and school accidents (8%). There was boy predominance for all accident types except for playground and at home accidents. The distribution of accident types differed according to age classes (p < 0.001). Twenty-six percent of patients were classed as overweight or obese - higher than data published by the WHO for the corresponding ages - with a higher proportion of overweight and obese boys than in the Swiss population (p < 0.0001). CONCLUSION Overall, differences in the fracture distribution were sex and age related. Overweight and obese patients seemed to be at increased risk of sustaining fractures. Our data give valuable input into future development of prevention strategies. The AO PCCF proved to be useful in epidemiological reporting and analysis of pediatric long bone fractures.

Abstract
Nursing personnel have consistently been ranked among the top ten professions impacted by musculoskeletal injuries. Inpatient pediatric nurses witnessed an increase in injuries and upon discovering limited evidence applicable to pediatrics, conducted a research study to evaluate the effectiveness of a safe patient handling program. Surveys were distributed to assess risk and workplace safety perceptions. Post-implementation, surveys revealed a statistically significant (p>0.0001) increase in staff perception of workplace safety, reduction in risk perception for several nursing tasks, and reduction in injury related costs. As a result of this program, workplace safety was improved through education and equipment provision.

Abstract
Young male soccer players have been identified as a target group for injury prevention, but studies addressing trends and determinants of injuries within this group are scarce. The goal of this study was to analyze age-specific trends in hospital-treated upper extremity fractures (UEF) among boys playing soccer in the Netherlands and to explore associated soccer-related factors. Data were obtained from a national database for the period 1998-2009. Rates were expressed as the annual number of UEF per 1000 soccer players. Poisson's regression was used to explore the association of UEF with the number of artificial turf fields and the number of injuries by physical contact. UEF rates increased significantly by 19.4% in boys 5-10 years, 73.2% in boys 11-14 years, and 38.8% in boys 15-18 years old. The number of injuries by physical contact showed a significant univariate association with UEF in boys 15-18 years old. The number of artificial turf fields showed a significant univariate association with UEF in all age groups, and remained significant for boys aged 15-18 years in a multivariate model. This study showed an increase of UEF rates in boys playing soccer, and an independent association between artificial turf fields and UEF in the oldest boys.

Abstract
BACKGROUND This study evaluates the effects of childhood obesity on fracture complexity and associated injuries in pediatric supracondylar humeral fractures. METHODS A billing query identified all patients who were two to eleven years of age and had undergone operative treatment for extension-type supracondylar humeral fractures over a 12.5-year period. Records were reviewed for demographic data, body mass index percentile, and injury data. Complex fractures were defined as type-3 supracondylar humeral fractures, supracondylar humeral fractures with intercondylar extension, or supracondylar humeral fractures with ipsilateral upper-extremity fractures. Logistic regression analyses were used to test relationships among body mass index subgroups, fracture complexity, elbow motion, preoperative and postoperative neurovascular status, and complications. RESULTS Three hundred and fifty-four patients met our inclusion criteria. Forty-one children were underweight (BMI in the <5th percentile), 182 were normal weight (BMI in the 5th to 85th percentile), sixty-three were overweight (BMI in the >85th to 95th percentile), and sixty-eight were obese (BMI in the >95th percentile). There were 149 patients, eleven of whom were obese, with isolated type-2 fractures and 205 patients, fifty-seven of whom were obese, with complex fractures. Thirty-two patients had preoperative nerve palsies and twenty-eight patients had postoperative nerve palsies. Using logistic regression, obesity was associated with complex fractures (odds ratio, 9.19 [95% confidence interval, 4.25 to 19.92]; p < 0.001), preoperative nerve palsies (odds ratio, 2.69 [95% confidence interval, 1.15 to 6.29]; p = 0.02), postoperative nerve palsies (odds ratio, 7.69 [95% confidence interval, 2.66 to 22.31]; p < 0.001), and postoperative complications (odds ratio, 4.03 [95% confidence interval, 1.72 to 9.46]; p < 0.001). Additionally, obese patients were more likely to sustain complex fractures from a fall on an outstretched hand than normal-weight patients (odds ratio, 13.00 [95% confidence interval, 3.44 to 49.19]; p < 0.001). CONCLUSIONS Obesity is associated with more complex supracondylar humeral fractures, preoperative and postoperative nerve palsies, and postoperative complications. To our knowledge, this study is the first to assess the implications of obesity on supracondylar humeral fracture complexity and associated injuries and it validates public health efforts in combating childhood obesity.

Abstract
In 2012, 32.3% of the French population over 18 years of age was considered overweight (25 ≤ BMI<30 kg/m(2)) and 15% obese (BMI ≥ 30 kg/m(2)). Worldwide, 2.8 million people die every year from the complications of obesity. In 2008, the prevalence of obesity was almost double that of 1980. Obesity is a genuine concern for the orthopedic surgeon, as it affects bones and soft tissues on the biomechanical and biochemical level. In traumatology, low-energy trauma is more frequent in obese patients and induces complex comminutive fractures of the extremities. In orthopedics, obesity is an independent risk factor for osteoarthritis, particularly for the knee joint. The goals of this review are to describe specific aspects of the care of obese patients in trauma and orthopedics surgery during the pre-, intra- and postoperative periods, as well as the risk-benefit ratio related to the treatment of the obese patients.

Abstract
BACKGROUND Childhood obesity gives rise to health complications including impaired musculoskeletal development that associates with increased risk of fractures. Prevention and treatment programs should focus on nutrition education, increasing physical activity (PA), reducing sedentary behaviours, and should monitor bone mass as a component of body composition. To ensure lifestyle changes are sustained in the home environment, programs need to be family-centered. To date, no study has reported on a family-centered lifestyle intervention for obese children that aims to not only ameliorate adiposity, but also support increases in bone and lean muscle mass. Furthermore, it is unknown if programs of such nature can also favorably change eating and activity behaviors. The aim of this study is to determine the effects of a 1 y family-centered lifestyle intervention, focused on both nutrient dense foods including increased intakes of milk and alternatives, plus total and weight-bearing PA, on body composition and bone mass in overweight or obese children. METHODS/DESIGN The study design is a randomized controlled trial for overweight or obese children (6-8 y). Participants are randomized to control, standard treatment (StTx) or modified treatment (ModTx). This study is family-centred and includes individualized counselling sessions on nutrition, PA and sedentary behaviors occurring 4 weeks after baseline for 5 months, then at the end of month 8. The control group receives counselling at the end of the study. All groups are measured at baseline and every 3 months for the primary outcome of changes in body mass index Z-scores. At each visit blood is drawn and children complete a researcher-administered behavior questionnaire and muscle function testing. Changes from baseline to 12 months in body fat (% and mass), waist circumference, lean body mass, bone (mineral content, mineral density, size and volumetric density), dietary intake, self-reported PA and sedentary behaviour are examined. DISCUSSION This family-centered theory-based study permits for biochemical and physiological assessments. This trial will assess the effectiveness of the intervention at changing lifestyle behaviours by decreasing adiposity while enhancing lean and bone mass. If successful, the intervention proposed offers new insights for the management or treatment of childhood obesity. TRIAL REGISTRATION ClinicalTrials.gov, NCT01290016.

Abstract
In most finite element (FE) studies of vertebral bodies, axial compression is the loading mode of choice to investigate structural properties, but this might not adequately reflect the various loads to which the spine is subjected during daily activities or the increased fracture risk associated with shearing or bending loads. This work aims at proposing a patient-specific computer tomography (CT)-based methodology, using the currently most advanced, clinically applicable finite element approach to perform a structural investigation of the vertebral body by calculation of its full six dimensional (6D) stiffness matrix. FE models were created from voxel images after smoothing of the peripheral voxels and extrusion of a cortical shell, with material laws describing heterogeneous, anisotropic elasticity for trabecular bone, isotropic elasticity for the cortex based on experimental data. Validated against experimental axial stiffness, these models were loaded in the six canonical modes and their 6D stiffness matrix calculated. Results show that, on average, the major vertebral rigidities correlated well or excellently with the axial rigidity but that weaker correlations were observed for the minor coupling rigidities and for the image-based density measurements. This suggests that axial rigidity is representative of the overall stiffness of the vertebral body and that finite element analysis brings more insight in vertebral fragility than densitometric approaches. Finally, this extended patient-specific FE methodology provides a more complete quantification of structural properties for clinical studies at the spine.

Abstract
Osteopenic fractures occur in children every day. At times the osteopenic nature of these fractures is painfully obvious, as in neurofibromatosis and osteogenesis imperfecta, while in many other situations overt osteopenia does not declare itself, such as in normal and obese children. Normal pediatric bone growth commonly involves periods of relative bone weakness. Childhood obesity creates a situation where bone is unable to fully adapt to the stresses placed upon it. Conditions like neurofibromatosis and osteogenesis imperfecta place pediatric bone at a distinct genetic disadvantage. This review will highlight recent research in these areas and provide radiographic examples of the treatment of osteopenic fractures in children.
