General Considerations
- Most commonly caused by diabetes today
- Bilaterally is rare in foot
- Disturbance in sensation leads to multiple microfractures
- Pain sensation is intact from muscles and soft tissue
- Distribution and causes
- Shoulders – syringomyelia, spinal tumor
- Elbows and wrists -- syringomyelia
- Hips – tertiary syphilis, diabetes
- Knees – tertiary syphilis (more bone production), diabetes (less bone production)
- Feet – diabetes, congenital insensitivity to pain, chronic alcoholism
