External fixator versus elastic stable intramedullary nail for treatment of metaphyseal-diaphyseal junction fractures of the pediatric distal femur: a case-control study. BMC Musculoskelet Disord 2024; 25:389. [PMID: 38762453 PMCID: PMC11102165 DOI: 10.1186/s12891-024-07469-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Accepted: 04/22/2024] [Indexed: 05/20/2024] Open
Abstract
BACKGROUND Several methods have been used for the treatment of pediatric distal femoral fractures, such as elastic stable intramedullary nail (ESIN), external fixator (EF) and plate osteosynthesis, but there has been no consensus about the optimal method. The purpose of this study was to compare the clinical outcome between EF and ESIN techniques used in metaphyseal-diaphyseal junction (MDJ) fractures of the pediatric distal femur. METHODS We retrospectively analyzed operatively treated MDJ fractures of pediatric distal femur between January 2015 and January 2022. Patient charts were reviewed for demographics, injury and data of radiography. All of the patients were divided into EF and ESIN groups according to the operation techniques. Malalignment was defined as more than 5 degrees of angular deformity in either plane. Clinical outcomes were measured by Flynn scoring system. RESULTS Thirty-eight patients were included in this study, among which, 23 were treated with EF, and 15 with ESIN. The mean follow-up time was 18 months (12-24 months). At the final follow-up, all of the fractures were healed. Although there were no statistical differences between the two groups in demographic data, length of stay, estimated blood loss (EBL), rate of open reduction, time to fracture healing and Flynn score, the EF was superior to ESIN in operative time, fluoroscopic exposure and time to partial weight-bearing. The EF group had a significantly higher rate of skin irritation, while the ESIN had a significantly higher rate of malalignment. CONCLUSION EF and ESIN are both effective methods in the treatment of MDJ fractures of the pediatric distal femur. ESIN is associated with lower rates of skin irritation. However, EF technique has the advantages of shorter operative time, reduced fluoroscopic exposure, and shorter time to partial weight-bearing, as well as lower incidence of malalignment.

[PMID: 37845172 DOI: 10.1016/j.injury.2023.111097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/14/2023] [Revised: 09/20/2023] [Accepted: 10/02/2023] [Indexed: 10/18/2023]
Abstract
INTRODUCTION Elastic nails have been widely used in the diaphyseal fracture fixation of long bones in adolescents. However, high complication rates have been reported in cases involving weights exceeding 55 kg. The existing nails are fabricated with different metals in clinical settings; however, the effect of the materials on the mechanical responses of the fractured bone remains unclear. Hence, the present study is conducted to compare the mechanical responses of typically used metals, namely titanium, stainless, and nickel-titanium, for elastic nails in the fixation of tibial diaphyseal fractures. MATERIAL AND METHODS A sawbone tube is used to determine the contact force, which is developed after constraining the nail inside the narrow canal using different nail materials. Furthermore, a finite element (FE) model of the tibial diaphyseal fracture is developed to predict the fracture gap deformation based on different nail materials under axial compression and bending loads. The push-out force in the FE simulation is compared with that of a case without an end cap. RESULTS In the sawbone tube, the results indicate that the contact force developed by the titanium nail is significantly higher than those developed by stainless and nickel-titanium nails. The contact forces developed by the titanium, stainless steel, and nickel- titanium nails are 385 (SD 34), 358 (SD 49), and 258 (SD 42) N, respectively. In the FE simulation, the titanium nail yields the highest push-out force when an end cap is not used, and the push-out forces in axial compression are 201, 183, and 87 N in the titanium, stainless, and nickel-titanium nails under axial compression, respectively. By contrast, the stainless nail yields the smallest gap deformation when an end cap is used. CONCLUSION Results of the present study show that the end cap is an important factor affecting the mechanical responses of nails fabricated using different materials. Titanium nails are preferred when an end cap is not used, whereas stainless nails are preferred when an end cap is used.

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. LEVEL OF EVIDENCE Level III, retrospective cohort study. See the Guidelines for Authors for a complete description of levels of evidence.

Abstract
BACKGROUND In children aged 3-5 years, femoral fractures are common and are frequently treated using flexible intramedullary nails (FIN) or spica casting. Recently, more surgeons have been relying on FIN surgery because of the high rate of complications associated with spica casts, such as skin irritation and re-adjustment surgery. We aimed to evaluate the effect of skin traction combined with braces in 3-5 years old children at our hospital. METHODS We retrospectively analyzed 125 children aged 3-5 years with femoral shaft fractures treated at our hospital between January 2010 and December 2020. We assigned 68 patients who underwent FIN surgery to Group A and 57 patients treated with skin traction and braces to Group B. Comparative analysis included the children's age, sex, side of the affected limb, cause of fracture, function of the knee joint, healing time of the fracture, duration of hospitalization, cost of hospitalization, and complications. The complications evaluated included joint dysfunction, pain, infection, pressure ulcers, angular deformities, limb length differences, re-fractures, nonunion fractures, and delayed union. RESULTS There were significant differences in and hospital costs (p = 0.001). Conversely, no statistically significant differences were observed in sex (p = 0.858), injury type (p = 0.804), age (p = 0.231), hospitalization time (p = 0.071), bone healing time (p = 0.212), and complications. Pressure ulcers, nonunion fractures, and delayed union did not occur in both groups. CONCLUSION Both methods had similar therapeutic effects and postoperative complications in children aged 3-5 years with femoral shaft fractures. Therefore, skin traction combined with braces is recommended for this population and for patients hospitalized in institutions where several beds are available, with a consequent possibility of prolonged hospitalization.

Abstract
Femoral shaft fractures in children have seen a number of interesting developments over the past 20 years. This is a retrospective cohort study looking into epidemiological and outcomes data of femoral shaft fractures in children treated at a tertiary centre in Wales from 2005-2021. Over a period of 16 years, there has been a significant increase in the number of rigid or elastic nailing and submuscular plating, coinciding with a dramatic reduction of external fixation for definitive treatment of diaphyseal femoral fractures. All patients above five years of age underwent operative fixation, with elastic or rigid intramedullary nailing the treatment of choice. Following multiple linear regression with 16 possible explanatory factors, this study found a statistically significant increase in time to union for open fractures, pre-operative translation, and operation time. Furthermore, there was a significant increase in post-operative leg length discrepancy for right versus left-sided fractures. Overall complication rates were 4% for minor and 8% for major complications. Complication rates were lowest for rigid intramedullary nailing and highest for external fixation. No cases of avascular necrosis were found for 27 rigid intramedullary nails inserted. Overall this study reports treatment choices and outcomes in keeping with current trends in management for paediatric femoral shaft fractures.

Abstract
BACKGROUND Pediatric femur fractures are a major trauma in children. Different treatment algorithms have been developed but indications for surgical treatment, especially in very young patients, are still controversial. Literature recommends surgical stabilization with elastic-stable intramedullary nailing (ESIN) starting at the age of 3 and non-operative treatment in younger patients. This study sought to present the outcome of patients younger than 3 years of age treated with ESIN for femur fractures. MATERIALS AND METHODS Inclusion criteria were patients younger than 3 treated with ESIN in femur fractures. Patient demographics, fracture characteristics, mechanism of injury, outcomes and complications were recorded using charts and X-rays. Primary outcome measures were time to mobility, fracture consolidation and surgical-related complications. RESULTS Between 2010 and 2020, 159 patients were treated with ESIN in femur fractures in our institution. A total of 30 patients met the criteria. The mean age was 2.1 ± 0.7 years (13 months-2.9 years). Most common mechanism was fall from standing height (60%). Other mechanisms were motor vehicle accidents as a pedestrian (10%) or as a passenger (10%) as well as direct blow trauma (20%). Femoral shaft fracture was the most common injury (80%). 5 subtrochanteric and one distal metaphyseal femur fractures were found. Mean length of stay was 2.0 ± 1.3 days. Radiographic controls were performed on day 1, 14 and 6 weeks after surgery if not otherwise specified or if complications occurred. 4.6 ± 1.2 (n 2-7) X-rays were performed on average after surgery. First radiographic consolidation signs were seen after 2.4 ± 0.6 weeks. Only one child showed surgical-related complication with a leg length discrepancy of 1 cm. In 10% of the patients, shortening after surgery of 1.7 ± 1.4 mm (0.3-3.1 mm) occurred. One child initially treated with traction therapy showed skin irritations and was operated with ESIN. No non-union or ESIN-related complications were found. Mean follow-up was 5.1 ± 4.4 months (4-24 months). First independent mobilization was seen at an average of 3.4 ± 1.1 weeks (2-6 weeks) after surgery. Implant removal was performed after 3.2 ± 1.3 months (2-8 months). No refracture after implant removal occurred. CONCLUSION Early results with ESIN show a reasonable and safe treatment option for femur fractures in toddlers and young children under the age of 3 with easy postoperative care, fast fracture union and early independent mobilization.

Abstract
BACKGROUND The management of femoral fractures in children between 3 and 5 years of age is still vividly debated. Therefore, we aimed to assess the basic attitude of parents if confronted with a hypothetical femoral fracture of their toddler. MATERIALS AND METHODS Parents of children aged between 12 and 36 months were asked for their preference after receiving detailed information on conservative and surgical treatment of femoral shaft fractures. Furthermore, we obtained information regarding the parents' gender, marital status, medical background, highest level of education and profession in a leading or non-leading position and if any of their children already had undergone any operations. The Freiburg Personality Inventory (FPI-R) questionnaire was used to assess parents' personality traits. RESULTS In total, 131 participants were included in this study. The vast majority (n = 116, 88.5%) preferred surgical treatment. The most frequently mentioned reasons for this decision were lack of acceptance, followed by faster reconvalescence, shorter hospital stay, less deformity or growth disorders and less stress on the child. The only reason stated against surgical treatment was the need of general anesthesia. A significantly higher rate of conservative procedures was noticed in self-employed participants and stress was found to significantly influence the treatment decision of the parents toward conservative treatment. CONCLUSION The majority of parents confronted with a hypothetical femoral fracture of their child questioned in this study opted for a surgical approach with elastic stable intramedullary nailing (ESIN). This corresponds with trends toward surgery in these cases in major trauma centers in Europe.
