Heel pad thickness: determination by high-resolution ultrasonography.
Summary
Heel pad thickness can be measured non-invasively using high-resolution ultrasonography. This method accurately assesses heel pad thickness, offering an alternative to traditional radiography for conditions like acromegaly and diabetes.
Area of Science:
- Endocrinology
- Radiology
- Medical Imaging
Background:
- Heel pad thickness is classically increased in acromegaly and long-term Dilantin therapy.
- Radiography is the standard method for measuring heel pad thickness, but involves radiation and magnification.
- Diabetic foot complications are a significant concern, and heel pad health is important.
Purpose of the Study:
- To evaluate the effectiveness of high-resolution ultrasonography for measuring heel pad thickness.
- To compare ultrasonography measurements with radiographic methods.
- To assess heel pad thickness in control subjects, diabetics, and patients with acromegaly.
Main Methods:
- A high-resolution 10-MHz superficial real-time scanner was used.
- Heel pad thickness was measured in 54 patients and 10 controls.
- Measurements were taken without radiation or magnification, unlike standard radiography.
Main Results:
- Average heel pad thickness in controls was 16.6 mm.
- Average heel pad thickness in 38 diabetics without ulcers was 17.8 mm.
- A single acromegalic patient had a heel pad thickness of 21 mm.
Conclusions:
- Ultrasonography is an effective, radiation-free alternative to radiography for measuring heel pad thickness.
- This imaging modality can be used to assess heel pad changes in various conditions.
- Further research can explore its utility in diagnosing and monitoring foot pathologies.
