Diagnosis of Charcot Foot Deformity

It may be difficult to diagnose Charcot foot in the early stages, so your doctor will discuss your symptoms in detail and perform a thorough foot examination. Diagnostic tests that may be performed include:

  • Imaging tests: X-rays and MRI scans are done to detect any deformity or injury to the bone and soft tissues.

  • Pinprick test: This test detects the ability to feel pain.

  • Neurometer test: This test detects dysfunction of the peripheral nerves.

Treatment for Charcot Foot Deformity

Early treatment helps in preventing the damage and deformity caused by the condition. The treatment measures include:

Conservative method involves:

  • Immobilization: Your doctor will instruct you to avoid exerting pressure on the foot and keep it immobilized. You will be provided with a cast, crutches, or wheelchair to rest your foot until symptoms improve.

  • Bracing and custom shoes: After your foot has healed, you will be placed in a brace or splint to maintain proper bone alignment for several months after which you will be provided with custom shoes with special inserts to protect your feet and prevent the formation of ulcers.

Surgical method

If conservative methods are unsuccessful, surgery is recommended. The different types of surgeries include:

  • Realignment bone surgery: This is also known as a reconstructive osteotomy. Your doctor shortens or lengthens the bone so that it alters the alignment to better support the joints.

  • Ankle fusion: Your doctor will insert screws and rods to lock the joint and restrict the movement of the ankle.

  • Prosthetic fitting: The severely damaged part of the foot is removed and a prosthetic device will be fitted.
