Radiographic Views for Toe Fractures
For suspected toe fractures, obtain anteroposterior (AP) and oblique radiographic views as the standard initial imaging approach.
Standard Imaging Protocol
The ACR Appropriateness Criteria 1 establish that radiographs are the mainstay of initial imaging for acute foot trauma, including toe fractures. While the guidelines emphasize a three-view study (AP, oblique, and lateral) for general foot trauma, the specific application to toe fractures requires some nuance:
- Toe fractures are not directly addressed by Ottawa rules 1, meaning clinical suspicion alone warrants imaging
- When a toe fracture is suspected, radiographs can document or rule out a fracture 1
- The standard approach includes AP and oblique views as most useful for identifying fractures and determining displacement 2
Why Three Views Matter
Research demonstrates that oblique views uniquely reveal abnormalities that would otherwise be missed 3. In a prospective study of 1,461 distal extremity examinations (including toes), the oblique view:
- Changed interpretation in 4.8% of cases
- Increased diagnostic confidence significantly (reducing equivocal findings from 13.9% to 8.4%)
- Was equally valuable across all distal extremities including toes 3
More recent evidence reinforces this: three-view examinations provide increased diagnostic accuracy and reduced misdiagnosis rates compared to two views 4.
Practical Application
For toe fractures specifically:
- Minimum: AP and oblique views are essential
- Optimal: Add lateral view when feasible to complete the three-view series
- The oblique view is particularly critical as it clarifies findings and reveals fractures not visible on AP alone 3
Clinical Context
Great toe fractures deserve special attention due to their weight-bearing role 5. For these injuries:
- Ensure complete three-view imaging
- Look for displacement, intra-articular involvement, and joint surface involvement >25%
- These factors determine need for orthopedic referral 2
Common Pitfall
The most significant error is obtaining only AP and lateral views while omitting the oblique 3. This occurs frequently in practice but compromises diagnostic accuracy. The oblique view costs nothing additional but provides substantial diagnostic value, particularly for detecting subtle fractures and assessing displacement 3, 4.
