Patients who undergo surgery to correct arthritis in the foot often are diabetics with a type of arthritis known as Char-cot foot. The average age of patients developing a Char-cot foot is 40 years.
About one-third of patients develop a Char-cot foot in both feet and/or ankles. This form of arthritis can develop suddenly and without pain. Quite suddenly, the bones in the foot and/or ankle can spontaneously fracture and fragment, often causing a sever deformity.
The arch of the foot often collapses, and pressure areas develop on the bottom of the foot, leading to open sores or ulcers.
While many of these deformities can be treated with non-surgical care, surgery may be required. Such instances may include:
- Chronic deformity with increased plantar pressures and risk of ulcers.
- Chronic deformity with significant instability that cannot be corrected by braces.
- Significant deformity that may include ulcers that don`t heal or respond to therapy.
