Isolated posterior malleolar fractures.
The American Journal of Emergency Medicine
|July 1, 1986
Summary
Isolated posterior malleolar fractures, rare ankle injuries, often result from foot compression or plantar flexion. These fractures require consideration in all ankle injury assessments.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Radiology
Background:
- Ankle fractures are common injuries presenting to emergency departments.
- The Lauge-Hansen classification system is widely used for categorizing ankle fractures.
- Isolated posterior malleolar fractures are infrequently documented.
Observation:
- This report details three cases of isolated posterior malleolar fractures.
- These injuries were observed in patients presenting to an emergency department.
- Mechanism of injury involved foot compression and/or plantar flexion.
Findings:
- Isolated posterior malleolar fractures are not explicitly included in the Lauge-Hansen classification.
- The rarity of these fractures may lead to underdiagnosis.
- These fractures are associated with specific injury mechanisms.
Implications:
- Clinicians should consider isolated posterior malleolar fractures in the differential diagnosis of all ankle injuries.
- Improved recognition may lead to more accurate diagnosis and treatment.
- Further research into the classification and management of these injuries is warranted.
