Abstract
Pediatric femur fractures in children aged 5 to 11 years are typically classified as length-stable versus length-unstable. For length-stable fracture patterns, there is frequent consensus among pediatric orthopaedic specialists regarding the appropriateness of flexible intramedullary nails, submuscular plates (SMP), or lateral-entry rigid intramedullary nails (LE-RIMN). With length-unstable fracture patterns, however, the decision is more complex. Age, weight, fracture pattern, fracture location, surgical technique, surgeon experience, several implant-specific details, and additional factors are all important when choosing between flexible intramedullary nail, SMP, and LE-RIMN. These familiar methods of fixation may all be supported by conflicting and sometimes heterogeneous data. When planning to treat length-unstable fractures in young children, surgeons should understand evidence-based details associated with each implant and how each patient-specific scenario affects perioperative decisions.

Abstract
PURPOSE OF THE STUDY Surgical options for paediatric femoral fractures include fl exible intramedullary nailing (FIN), plating, and external fi xators. Length unstable fractures are usually spiral, long oblique, or comminuted and are often associated with > 2 cm of shortening. The purpose of this study was to see whether FIN is effective for managing unstable femur fractures in children. MATERIAL AND METHODS An electronic literature search was performed up to 25 February 2022 in Cochrane Library, PubMed, and Embase databases using a combination of MeSH search terms and keywords related to the population (e.g., "child" AND "diaphyses" AND "femur"), and intervention (e.g., "nail" OR "ESIN"). The data extracted included the study details, Demographic data, surgical details, postoperative immobilization, complications, and outcome. RESULTS Eight studies with a total sample size of 369 patients were reviewed. The mean operative time, blood loss, and length of stay in the hospital were 67.62±12.32 minutes, 33.82±16.82 ml, and 4.9±1.27 days, respectively. The results were excellent in 61.92% of the patients, satisfactory in 32.61%, and poor in 5.43%. 4.54% of patients had major complications requiring reoperation and 32.46% of patients had minor complications. the most common complication was nail prominence seen in 26.30% of patients. Locked Ender's nail was associated with the least reoperation, malunion, and LLD rate compared to other types of FIN. CONCLUSIONS FIN along with a single walking spica cast is a good choice in all forms of paediatric femoral fracture patterns allowing proper alignment and rotation. Locked Ender's nail is safe and effective for managing unstable paediatric femur fracture. KEY WORDS pediatric femur fracture, length unstable, fl exible intramedullary nailing, submuscular plating, Flynn criterion.

Abstract
BACKGROUND The treatment modalities for pediatric femoral shaft fractures are determined by their age, weight, and fracture pattern. Rigid intramedullary nailing (RIN) is usually recommended for patients >11 years of age, and elastic intramedullary nailing (EIN) has been used for patients under 10 years. However, little is known about the use of RIN in patients aged 8 to 10 years. We examined the differences in patients with femoral shaft fractures who were treated with EIN or RIN in terms of (1) fracture healing; (2) changes of anatomic parameters; and (3) related complications. METHODS We retrospectively reviewed 54 patients between 8 and 10 years of age, with femoral shaft fractures, who were treated with either EIN or RIN between 2011 and 2020. Lateral trochanteric entry was used for RIN procedure. The mean follow-up period was 26.4 months (range, 6 to 113 mo). There were 17 patients in the EIN group and 37 patients in the RIN group. The mean age at the time of surgery was 1 year younger in the EIN group ( P <0.01). The mean weight of the patient was significantly heavier in the RIN group compared with the EIN group. RESULTS Complete union of the fracture was achieved slightly faster in the RIN group at 3.4 months compared with 3.7 months in the EIN group ( P =0.04). There were no clinically significant changes of the anatomic parameters in either group, including neck shaft angle and articulotrochanteric distance. There was no evidence of avascular necrosis at the time of final follow-up for either group. There were no significant differences in postoperative complications between the groups. CONCLUSION RIN using lateral trochanteric entry is a feasible surgical option for femoral shaft fractures in patients 8 to 10 years of age that are heavier than 40 kg or with unstable fracture patterns.

Abstract
Diaphyseal femur fractures are common in pediatric orthopaedic settings. A patient-specific treatment plan incorporates several factors, including age, weight, fracture pattern, associated injuries, and social considerations. Nonaccidental trauma should be considered in children younger than 3 years. In general, young children are treated with noninvasive immobilization (Pavlik harness or early hip spica casting) while school-aged children are treated with internal fixation. Internal fixation options include flexible intramedullary nails, rigid locked intramedullary nails, and plate osteosynthesis. Flexible intramedullary nails have the best outcomes in children of appropriate weight, aged 5 to 11 years, with stable fracture patterns. Lateral-entry rigid intramedullary nails have been designed for use in older children. External fixation is usually reserved for complex scenarios. Regarding all treatment methods, surgeons should be aware of several technical factors necessary to optimize outcomes.

Abstract
Shaft fractures of the lower extremities are rare during adolescence. Conservative treatment is no longer used for the upper leg and the significance is declining for the lower leg, as only minor axis deviations and malrotations of the shaft are acceptable and conservative therapy is associated with severe impairments in the daily routine; however, conservative treatment is still an option for femoral fractures in children < 3 years of age and for stable fractures of the lower leg. Various osteosynthesis procedures can be used depending on the body weight and epiphyseal maturation. Elastic stable intramedullary nailing is the first choice, followed by solid adolescent femoral or tibial nailing for higher body weights and external fixation for open or multifragmentary fractures. Plate osteosynthesis is an established alternative. Following correct surgical treatment, all fractures have movement and at least partial load-bearing stability and the results are satisfactory. Regular controls are recommended up to the end of the growth period.

Abstract
BACKGROUND Femoral fractures are the most common cause of fracture-related admissions. Unplanned return to the operating room (UpROR) is a major event and imposes a substantial burden on the family and health care system. The purpose of this study was to determine the incidence of complications and early UpROR during the first 6 months following treatment of femoral fractures and their risk factors. METHODS In an institutional review board-approved study, a retrospective review of all patients who were treated for a femoral fracture during a 10-year period at a pediatric tertiary care center was performed. Patients less than 18 years old with a diaphyseal fracture and complete records were included, and nondiaphyseal or pathologic fractures, as well as underlying metabolic or genetic disorders, were excluded. All clinic visits in the first 6 months after treatment were reviewed, and all complications and UpRORs were extracted. Patients were grouped based on their age (below 5, 5 to 11, above 11 y old) at initial treatment, and statistical tests were used to infer differences between groups. RESULTS Overall, 841 fractures in 832 patients were included, with a mean age of 5.5±4.8 years fracture, of which 72% were male. A total of 106 complications (12.6%) and 45 UpRORs (5.3%) were encountered during the study period. Patients with and without UpROR had similar demographics and injury and treatment characteristics. Loss of reduction was the most common reason for UpROR (58%), followed by implant-related complications. Flexible nails had the highest risk of UpROR among patients who were initially treated surgically (P=0.03). CONCLUSIONS Our findings indicate that children under the age of 5 years have a 5% risk of UpROR in the first 6 months after the fracture, mainly for repeat spica casting due to loss of reduction. Patients aged 5 years or older have an ∼6% risk of UpROR, mainly related to complications of flexible nails. The findings of this study are important when consulting families on different treatments of diaphyseal femoral fractures. LEVEL OF EVIDENCE Therapeutic level III-retrospective cohort study.

Abstract
BACKGROUND Pediatric femur fractures are commonly treated with flexible intramedullary nails (FIN). However, there is controversy regarding the effect of patient weight on outcomes and complications. The purpose of this meta-analysis was to review the literature and describe implant choice, analyze complication, and reoperation rates; as well as the report clinical and radiographic outcomes of FIN in pediatric patients weighing ≥40 kg with femoral shaft fractures. METHODS A systematic review was performed of all retrospective and prospective studies focusing on the use of FIN in heavy children in Medline, Cochrane, and Web of Science databases. Data extraction was performed and summarized using descriptive statistics. Quality assessment was performed using the Newcastle-Ottawa Scale. Meta-analysis was performed for complications using pooled data from included studies. RESULTS The initial search strategy yielded 177 references, and after exclusions, 5 studies were included. The majority of studies were retrospective, and the most commonly used implants in heavier patients were titanium FIN and stainless steel Enders FIN. There were higher rates of radiographic nonunion and malunion, complications, and reoperations for refracture; and nonunion in heavier children treated with FIN. Meta-analysis performed on 4 applicable studies showed the overall complication rate was higher in the heavier patients compared with lighter patients (30.6% vs. 11.1%) with a relative risk of 1.20 [95% confidence interval (CI), 1.02-1.41]. Heavier patients also had higher rates of major complications (relative risk, 1.32; 95% CI, 1.03-1.69) but similar minor complications (relative risk, 1.13; 95% CI, 0.90-1.41). CONCLUSIONS Heavier children have worse radiographic outcomes and higher complication rates with the use of FIN for femoral shaft fractures. Additional research is needed to determine the effect of FIN material on clinical outcomes in heavier children, and the relationship between weight and other known risk factors for poor outcome in FIN, such as length stability.

Abstract
Femoral fractures in childhood are rare and are usually the result of severe trauma. Conservative treatment (overhead extension, hip spica cast) can be used in children up to 3 years of age and beyond that elastic stable intramedullary nailing (ESIN) is the method of choice. The prognosis is very good if the surgical technique is adequate. In adolescents > 50 kg in body weight solid nails implanted via the greater trochanter are an alternative (adolescent lateral femoral nail, ALFN). External fixators and plate osteosynthesis are indicated in special situations. Femoral neck fractures are very seldom seen in this age group. Besides Kirschner (K)-wires and screw osteosynthesis a special pediatric hip plate is available in this situation. In the distal metaphysis mostly stable fractures occur in disabled children, which can usually be treated conservatively. In addition, pathological fractures occur in juvenile bone cysts and complex injuries in adolescents, which need stabilization by descending ESIN or with plates. At the distal growth plate relevant growth disturbances are possible.

Abstract
OBJECTIVES To determine our complication rate in pediatric femoral shaft fractures treated with flexible elastic nailing and to determine fracture characteristics that may predict complications. DESIGN Retrospective cohort study. SETTING One Level 1 and One Level 2 academic trauma centers. PATIENTS/PARTICIPANTS One hundred one pediatric femoral shaft fractures treated from 2006 to 2018. MAIN OUTCOME MEASUREMENT Major and minor complications. RESULTS One hundred one femurs met inclusion criteria. The average age was 7 years (range 3-12 years). The average weight was 29.0 kg (range 16-55 kg). The average follow-up was 11 months (6-36 months). Ninety-three patients underwent elective implant removal at our institution. Fifty-one of the 101 (50%) fractures were "unstable" patterns. Ninety-three percent had implants that filled >80% of the canal (69 titanium and 32 stainless steel). Seventeen percent (18) had cast immobilization. All fractures went on to union. No patient required revision surgery for malunion as follows: 6 had coronal/sagittal malalignment >10 degrees, 3 had malrotation >15 degrees, and none had a leg length inequality >1 cm. Three patients had an unplanned surgery as follows: 2 for prominent implants and 1 for refracture after a second injury. There were no patient, fracture, or treatment characteristics that were predictive of complications or unplanned surgery, including "unstable" fractures (P = 0.78). CONCLUSION Our study demonstrates that flexible elastic nailing can be safely used in most pediatric femoral shaft fractures, including those previously described as "unstable."

Abstract
BACKGROUND One third of paediatric femoral fractures occur between the ages of 5 and 12. The American Academy of Orthopaedic Surgeons (AAOS) provide evidence-based guidance for treating such fractures that occur in children under 5 and over 12 but not for this age cohort. We aimed to synthesise the available evidence comparing flexible nailing versus plating techniques for diaphyseal femoral fractures in children between the ages of 5 and 12. METHODOLOGY A systematic review of interventional and observational studies was performed using MEDLINE, EMBASE, Cochrane CENTRAL, Web of Science, WHO Global Index Medicus and LILACS. The search strategy combined keywords for: children, diaphyseal femoral fractures, plates and nails. Two independent reviewers screened, selected, assessed quality and extracted data from identified studies. The primary outcome was overall complication rates. Secondary outcomes assessed rates of individual complications, and operative variables (e.g. operative time, blood loss). RESULTS Five studies fulfilled the eligibility criteria. No RCTs were identified. The studies included 308 femoral fractures in 306 patients: 174 fractures were treated with flexible nailing and 134 with plating. The post-operative complication rate was 27.0% (n = 47) after flexible nails and 12.7% (n = 17) after plating, relative risk 2.13 (95% CI 1.28, 3.53; p = 0.0035). The relative risk of malunion was 3.59 (95% CI 1.05, 12.25; p = 0.0409) with flexible nails and of prominent metalwork was 5.39 (95% CI 1.25, 23.31; p = 0.0241) with flexible nails. CONCLUSIONS Data on this topic for this age group is limited despite accounting for one third of paediatric femoral fractures. This review identified a significantly increased relative risk of all complications, and in particular with respect to malunion and prominent metalwork when fractures in this cohort are treated with flexible nails compared to plates. A multi-centre randomised trial to determine if either treatment is superior would be justified.

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
PURPOSE Fractures of the femoral shaft in children are common. The rates of bone growth and remodeling in children vary according to their ages, which affect their respective management. METHODS This paper evaluates the incidence and patterns of pediatric femoral shaft fracture and the current concepts of treatments available. RESULTS The type of fracture-closed or open; stable or unstable-needs to be taken into account. Child abuse should be suspected in fractures sustained by infants. For younger children, non-surgical management is preferred, which include Pavlik harness (< 6 months old) and early spica casting (6 months to 6 years old). Older children (> 6 years old) usually benefit from surgical treatments as outcomes of non-surgical alternatives are worse and are associated with prolonged recovery times. These operative measures for older children that are 6-12 years old include elastic stable intramedullary nailing and submuscular plating. Factors to be considered when devising an appropriate intervention include body mass, location of injury, and nature of fracture. For adolescent and skeletally mature teenagers (> 12 years old), rigid antegrade entry intramedullary fixation is indicated. In the event of open fractures or polytrauma, external fixation should be considered as a temporary treatment method for initial fracture stabilization. CONCLUSION An age-based and evidence-based algorithm has been proposed to guide surgeons in the process of evaluating an appropriate treatment.

Abstract
BACKGROUND Flexible intramedullary nailing (FIMN) is relatively contraindicated for pediatric length unstable femoral fractures.
AIM To evaluate FIMN treatment outcomes for pediatric diaphyseal length unstable femoral fractures in patients aged 5 to 13 years.
METHODS This retrospective study includes pediatric patients (age range 5-13 years) who received operative treatment for a diaphyseal femoral fracture at a single institution between 2013 and 2019. Length unstable femur fractures treated with FIMN were compared to treatment with other fixation methods [locked intramedullary nailing (IMN), submuscular plating (SMP), and external fixation] and to length stable fractures treated with FIMN. Exclusion criteria included patients who had an underlying predisposition for fractures (e.g., pathologic fractures or osteogenesis imperfecta), polytrauma necessitating intensive care unit care and/or extensive management of other injuries, incomplete records, or no follow-up visits. Patients who had a length stable femoral fracture treated with modalities other than FIMN were excluded as well.
RESULTS Ninety-five fractures from ninety-two patients were included in the study and consists of three groups. These three groups are length unstable fractures treated with FIMN (n = 21), length stable fractures treated with FIMN (n = 45), and length unstable fractures treated with either locked IMN, SMP, or external fixator (n = 29). P values < 0.05 were considered statistically significant. Patient characteristic differences that were statistically significant between the groups, length unstable with FIMN and length unstable with locked IMN, SMP, or external fixator, were average age (7.4 years vs 9.3 years, respectively), estimated blood loss (29.2 mL vs 98 mL, respectively) and body mass (27.8 kg vs 35.1 kg, respectively). All other patient characteristic differences were statistically insignificant. Regarding complications, length unstable with FIMN had 9 total complications while length unstable with locked IMN, SMP, or external fixator had 10. Grouping these complications into minor or major, length unstable with locked IMN, SMP, or external fixator had 6 major complication while length unstable with FIMN had 0 major complications. This difference in major complications was statistically significant. Lastly, when comparing patient characteristics between the groups, length unstable with FIMN and length stable with FIMN, all characteristics were statistically similar except time to weight bearing (39 d vs 29 d respectively). When analyzing complication differences between these two groups (9 total complications, 0 major vs 20 total complications, 4 major), the complication rates were considered statistically similar.
CONCLUSION FIMN is effective for length unstable fractures, having a low rate of complications. FIMN is a suitable option for length stable and length unstable femur fractures alike.

Expert Consensus for a Principle-based Classification for Treatment of Diaphyseal Pediatric Femur Fractures. J Pediatr Orthop 2020; 40:e669-e675. [PMID: 32251113 DOI: 10.1097/bpo.0000000000001550] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/07/2023]
Abstract
INTRODUCTION Recent studies demonstrate considerable deviation from the American Academy of Orthopaedic Surgeons (AAOS) evidence-based guidelines for the treatment of pediatric diaphyseal femur fractures (PDFFs). This study aimed to determine if expert-consensus can be reached on a principle-based classification to be applied broadly to a wide variety of PDFF scenarios and if outcomes correspond to adherence to the classification. METHODS A 2-stage study was performed. First, a survey of experts using a principle-based approach to PDFF. We conducted a survey of 17 thought-leaders (criteria≥20 y' experience+authors of the seminal pediatric femur fracture studies) who were asked to classify 15 cases of PDFF using the principle-based classification for agreement. Next, we conducted a retrospective review of 289 consecutive PDFF treated (2011-2015) at a level 1 pediatric trauma center. For each case, we compared the actual treatment and proposed "ideal" principle-based classification. We then compared clinical results and outcome data points including the length of stay, physician visits, and hospital charge data. RESULTS A substantial (κ=0.7) expert-agreement was noted for assigning treatment principles with near-perfect (κ=0.93) agreement on conservative versus surgical management. We obtained agreement on employing a flexible implant (κ=0.84) rigid fixation (κ=0.75) and damage control philosophy (κ=0.64). Suboptimal clinical results were noted in 43% of the undertreated patients (24/56), 18.8% of the adequately treated, and 14.3% of overtreated (P<0.01) patients. An increasing trend for the length of hospital stay and a number of clinic visits was noted as the treatment class increased (P<0.01). Charges were 4.2 times higher for an episode of operative versus nonoperative care (P<0.01). Rigid fixation (class 4) had significantly (P=0.01) higher total and material charges than flexible fixation (class 3). DISCUSSION The proposed classification has a substantial agreement among thought-leaders. Clinical results demonstrated significantly more suboptimal results in undertreated fractures, compared with ideally treated or more invasively treated fractures. More invasive treatments led to increased burden to families and the system in terms of length of stay and hospital charges. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Closed reduction (CR) is sufficient to reduce the majority of femur fractures treated with flexible intramedullary nailing (FIN). No previous study has examined factors associated with failed CR of pediatric femoral shaft fractures treated with FIN. We sought to determine preoperative factors associated with failed CR. We hypothesized that fracture, patient, and surgeon characteristics would impact the need for open reduction (OR). METHODS A retrospective review of children treated for femur fracture between 2012 and 2017 at a tertiary pediatric hospital was performed. Comparisons were made between 2 groups: FIN with CR group and FIN that required OR group. Demographic and baseline characteristics were compared between treatment groups using either χ tests or Fisher exact tests for categorical variables and general linear models for continuous variables. Odds ratios with 95% confidence intervals were calculated using univariate logistic regression tests. RESULTS Of 449 consecutive pediatric femur fractures treated at our center, 85 children were treated with FIN and constituted the study cohort. CR failed in 14 patients (16.5%) necessitating OR of the fracture site. Significant differences between study groups were found in fracture location (P=0.018), the mechanism (P=0.003), and displacement on the anteroposterior radiograph (P=0.027). Surgical time was found to be longer in the OR group (P=0.010). We identified 3 preoperative predictors of OR for FIN including fractures caused by high energy mechanisms (odds ratio=7.5), distal third fractures (odds ratio=15.3), and fracture displacement on the anteroposterior view (odds ratio=1.06). Surgeon years in practice, patient weight, age, and time from injury to surgery were not associated with OR. CONCLUSIONS This study presents 3 preoperative risk factors that predict the need for OR of femur fractures treated with FIN. Surgical time was longer in cases that required OR. Our findings suggest that surgeons should avoid lengthy attempts at CR and consider a lower threshold for OR of at-risk fractures or use another technique other than flexible nails. LEVEL OF EVIDENCE Level III-prognostic.

Abstract
Femoral fractures can be common in nonambulatory patients with myopathies because they present with notable osteoporosis. From the orthopaedic perspective, this can be complicated by a pre-existing knee flexion contracture and small femoral shaft size. The goals of treatment are to reduce external immobilization, maximize comfort for transfers, prevent functional loss, and preclude refracture. The purpose of our work is to describe the anesthetic and orthopaedic considerations in treating a bed-bound adult patient with nemaline dystrophy and a midshaft femur fracture. The authors have obtained the patient's informed written consent for print and electronic publication of the case report.

Musculoskelet Surg 2019; 103:23-30.

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
Obese children with high-energy injuries present with more severe injuries, more extremity injuries, and higher Injury Severity Scores. They are at increased risk for complications, prolonged ventilation, and ICU stay and have increased mortality. Obesity is associated with altered bone mass accrual and higher fracture rates. Obese patients have a higher risk of loss of reduction of forearm fractures, more severe supracondylar fractures, and a higher likelihood of lateral condyle fractures. Obese patients are more likely to have complications with femur fractures and have higher rates of foot and ankle fracture.

Abstract
BACKGROUND Rotational malalignment is an important and not always avoidable complication after surgical treatment of femoral shaft fractures. The purpose of this study was to determine the incidence of rotational malalignment in children after surgical treatment of femoral shaft fractures and to identify potential patient- and treatment-related risk factors based on data obtained from CT scans. METHODS We conducted a retrospective analysis of all patients aged less than 15 years with femoral shaft fractures admitted to our level 1 trauma centre between January 2004 and July 2014. Patients having obtained postoperative CT scans were included for the determination of rotational malalignment. A difference of greater than 15° in femoral torsion between both legs was considered as clinically relevant. Additionally, demographic data and clinical information such as fracture type, treatment method, fluoroscopy time and operating time were reviewed. RESULTS A total of 24 patients were enrolled in this study. Clinically relevant femoral malrotation was identified in 10 patients (41.6%). Surgical revision was performed in 7 patients (29.2%). There was no association between the type of surgical procedure, age and the incidence and/or amount of femoral malrotation. CONCLUSIONS The data suggest that relevant femoral malrotation is an evident problem after surgical treatment of femoral shaft fractures in children that requires critical postoperative assessment. LEVEL OF EVIDENCE Level III, retrospective study.
