• Surgical treatment is beneficial in Charcot foot or ankle cases refractory to offloading and immobilization. Surgery is also beneficial in the case of recalcitrant ulcers.
• The initial management of acute neuropathic fractures and dislocations should not differ from initial management techniques for other fractures.
• Exostectomy is useful in relieving any bony pressure that orthotics and prosthetics cannot accommodate.
• Lengthening of the Achilles tendon or gastrocnemius tendon reduces forefoot pressure. It also improves the alignment of the ankle and hindfoot to the midfoot and forefoot.
• Arthrodesis can be useful in patients with instability, pain or recurrent ulcerations who fail non-operative treatment, despite a higher rate of incomplete bony union.
• For severe Charcot arthropathy of the ankle, one could consider surgical management as a primary treatment.
The Charcot foot syndrome is a complex complication of diabetes and neuropathy, but physicians can prevent major deformity associated with this syndrome. We should have a high index of suspicion when examining a neuropathic patient with a hot, swollen foot. If one implements existing treatments early, they are effective at preventing ulceration and bony destruction.
Offloading is the most important initial treatment and given the risk benefit ratio, offloading should begin even during the diagnostic period. Other pharmacologic treatments have not shown conclusive benefits. Surgical treatments can be effective when experienced surgeons perform them. However, one should reserve surgical treatment for cases in which offloading and bracing fail, or in cases of severe instability.
Jean-Martin Charcot, MD, concluded his seminal paper on tabetic arthropathies, which now bear his name, with the statement “sera continue,” which means “to be continued.” More than 130 years later, his statement remains true. There is much we have to learn about the pathophysiology of this condition, which will generate future therapies.
