Joints may dislocate in the foot or ankle. With repetitive trauma and degeneration, the joints in the foot may eventually collapse, causing the foot to become deformed and take on an abnormal shape such as a rocker-bottom appearance. The deformity can lead to foot sores and ulcers, bone infection osteomyelitisand if not treated aggressively, amputation.
Neuropathic osteoarthropathy, or Charcot foot, is an inflammatory process that affects the soft tissues, bones, and joints in the foot or ankle. Read on to understand your risk for Charcot foot, as well as tips for proactive behaviors that can help you avoid it or stop its progress. Charcot foot can result from complete or near-complete numbness in one or both feet or ankles.

The diabetic Charcot foot syndrome is a serious and potentially limb-threatening lower-extremity complication of diabetes. First described inthis enigmatic condition continues to challenge even the most experienced practitioners. Now considered an inflammatory syndrome, the diabetic Charcot foot is characterized by varying degrees of bone and joint disorganization secondary to underlying neuropathy, trauma, and perturbations of bone metabolism.
Charcot foot is a rare but serious complication that can affect persons with peripheral neuropathyespecially those with diabetes mellitus. Charcot affects the bones, joints, and soft tissues of the foot or ankle. The bones become weak and can break and the joints in the foot or ankle can dislocate.

Although Charcot neuroarthropathy occurs in a small percentage 5 percent of the diabetic population, the natural disease course is associated with severe morbidity including chronic ulcerations, infections and amputations. However, the recent advent of rocker bottom reconstruction provides the podiatric surgeon with another tool in the fight for limb preservation. Those with ulcerations secondary to Charcot foot deformity are part of a complex subset of patients who require a multidisciplinary approach. The physician who intends to treat Charcot ulcerations successfully must have knowledge of podiatric surgery, plastic surgery and infectious disease, not to mention endocrinology, neurology, cardiology and vascular surgery just to name a few.
Charcot neuroarthropathy CN is a severe joint disease in the foot and ankle that can result in fracture, permanent deformity, and limb loss. It is a serious and potentially limb-threatening lower-extremity late complication of diabetes mellitus. Charcot neuroarthropathy CN was first described by neurologist Jean-Martin Charcot in in a group of patients with syphilis, but the mystery of pathophysiology remains 1 — 3.
Osteomyelitis: Osteomyelitis in a diabetic with neuropathy is infection of the bone that usually results from contiguous spread of a skin ulcer. Consequently, the most common location for osteomyelitis is not in the midfoot, but at the pressure points of the forefoot metatarsal heads, IP joints and in the hindfoot at the plantar aspect of the posterior calcaneus. To determine whether osteomyelitis is present, place a marker on the ulcer or sinus tract and track it down to the bone and evaluate the MR- signal intensity of the marrow 1.
