Overview
Pilon fractures involve the talus bone within the ankle mortise, often resulting from axial loading injuries and frequently associated with fibular fractures. These injuries are complex and can lead to significant functional impairment if not managed appropriately 1.Diagnosis
Clinical Presentation: Severe pain, swelling, and inability to bear weight 1.
Imaging: Radiographic evaluation including AP, lateral, and mortise views essential for classification 1.
Grading Systems: Utilization of Ruedi or AO classification systems to assess fracture complexity 1.Management
Fibular Fixation: Open reduction and plate fixation of the fibula recommended for better outcomes compared to pin fixation or conservative management 1.
Pilon Fragment Stabilization: Open reduction and internal fixation (ORIF) for the pilon fragment to ensure anatomical reduction 1.
Conservative Measures: Reserved for less severe cases or as adjunctive support post-operative immobilization 1.Special Populations
Elderly: Management considerations include lower demand for high-level activity, potentially favoring less invasive approaches 1.
Comorbidities: Presence of comorbidities may necessitate tailored surgical approaches and extended rehabilitation plans 1.Key Recommendations
Stabilize the Fibula: Open reduction and plate fixation of the fibula in pilon fractures improves clinical outcomes and reduces malunion and arthrosis risks compared to conservative or pin fixation methods (Evidence: Moderate) 1.
Anatomical Reduction: Aim for anatomical reduction of both the pilon and fibular fractures to optimize functional outcomes (Evidence: Moderate) 1.
Tailored Approach for Special Populations: Consider patient-specific factors such as age and comorbidities when planning surgical and rehabilitation strategies (Evidence: Expert opinion) 1.References
