Insights
Elastic-stable intramedullary nailing (ESIN) is a safe and effective treatment for femur fractures in children under three years old. This method allows for early mobilization and quick fracture healing with minimal complications.
Area of Science:
- Pediatric Orthopedics
- Trauma Surgery
- Pediatric Surgery
Background:
- Pediatric femur fractures are a significant trauma in children.
- Treatment indications for surgical intervention, particularly in very young children, remain a subject of debate.
- Current literature suggests elastic-stable intramedullary nailing (ESIN) for children aged 3 and above, with non-operative management for younger patients.
Purpose of the Study:
- To evaluate the outcomes of treating femur fractures in patients younger than 3 years old using elastic-stable intramedullary nailing (ESIN).
- To assess the safety and efficacy of ESIN in this specific pediatric age group.
Main Methods:
- A retrospective review of patients under 3 years old treated with ESIN for femur fractures between 2010 and 2020.
- Data collected included patient demographics, fracture characteristics, injury mechanisms, and outcomes.
- Primary outcome measures were time to mobility, fracture consolidation, and surgical complications.
Main Results:
- Thirty patients met the inclusion criteria, with a mean age of 2.1 years.
- The most common injury mechanism was falls from standing height (60%).
- Mean time to radiographic consolidation was 2.4 weeks, with early independent mobilization at 3.4 weeks post-surgery. Only one complication (leg length discrepancy) was noted, with no non-unions or ESIN-related issues.
Conclusions:
- Elastic-stable intramedullary nailing (ESIN) demonstrates promising early results as a safe and effective treatment for femur fractures in toddlers and young children under 3 years.
- The procedure is associated with straightforward postoperative care, rapid fracture union, and facilitates early patient mobilization.
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.
