Pedal manifestations of DISH

Area of Science:

• Rheumatology
• Orthopedics
• Radiology

Background:

• Diffuse idiopathic skeletal hyperostosis (DISH), also known as Forestier's disease, is a skeletal disorder.
• Characterized by excessive bone formation at specific sites.
• While spinal manifestations are well-known, extraspinal involvement, especially in the foot, is significant.

Purpose of the Study:

• To review the radiographical, pathological, and clinical features of DISH.
• To emphasize the foot as a key target organ in DISH.
• To highlight foot abnormalities that aid in diagnosing DISH.

Main Methods:

• Review of existing literature on DISH.
• Analysis of radiographical, pathological, and clinical data.
• Focus on extraspinal manifestations, particularly in the foot.

Main Results:

• DISH involves excessive bone formation beyond the spine.
• The foot is a common extraspinal site affected by DISH.
• Specific foot abnormalities can suggest a diagnosis of DISH.

Conclusions:

• DISH is not limited to spinal involvement.
• The foot plays a crucial role in the manifestation and diagnosis of DISH.
• Recognizing foot abnormalities is essential for accurate DISH diagnosis.
