A unique closed abduction-external rotation ankle fracture.
The Journal of Trauma
|January 1, 1989
Summary
This case report details a rare ankle fracture involving the medial malleolus and deltoid ligament, likely caused by severe road trauma forces. Such complex injuries highlight the potential for unusual fracture combinations in high-energy incidents.
Area of Science:
- Orthopedic Surgery
- Trauma Medicine
- Radiology
Background:
- Ankle fractures are common, but specific injury patterns can be rare.
- Understanding the biomechanics of ankle injuries is crucial for diagnosis and treatment.
- Road trauma frequently involves high-energy forces capable of producing complex injuries.
Observation:
- A unique case of a closed abduction-external rotation ankle fracture is presented.
- This fracture pattern includes a combined medial malleolar fracture and deltoid ligament avulsion.
- No similar cases were found in a thorough literature review.
Findings:
- The report is supported by operative photographs, radiographs, and a 20-month follow-up.
- A mechanical explanation for this specific injury pattern is proposed.
- The complexity of forces in road trauma can result in uncommon injury combinations.
Implications:
- This case expands the understanding of potential ankle fracture patterns.
- It emphasizes the need for careful evaluation of high-energy ankle injuries.
- The findings may inform treatment strategies for complex ankle fractures.
