Reconstructive Surgical Management of Charcot Neuropathy of the Foot and Ankle: A Retrospective Study

Abstract

Category: Diabetes Introduction/Purpose: Treatment of Charcot neuropathy (CN) of the foot and ankle remains a challenge for both patient and surgeon. Non-operative treatment with immobilization in a cast/orthosis has long been the mainstay of treatment, but more recently surgical intervention-with attention to internal fixation-has gained interest because of the poor long-term outcomes with non-operative care. Methods: To assess long-term outcomes between CN patients managed with reconstructive surgeries at a tertiary referral center; a retrospective chart review analyzed comorbidities, demographics, and complications (ulceration, infection, and below the knee amputation). Results: Over the last 16 years, 31 patients with CN were treated with internal fixation (midfoot fusion, open reduction, or hindfoot fusion nail). Average BMI was 33.5, average number of comorbidities was 2.93, and the percentage of patients with a vascular deficit was 19.3%. The rate of infection and ulceration prior to surgery was 19.4% (6/31 patients) and 45.2% (14/31 patients) respectively. After surgery, the rate of new infections was 38.7% (12/31 patients). The rate of new ulcerations was 41.9% (13/31 patients). The rates of below the knee amputation was 19.4% (6/31 patients). Conclusion: A 16-year retrospective review of operative management of Charcot neuropathy in 31 patients at a tertiary referral center found high rates of ulceration, infection, and amputation in patients treated with internal fixation. This study could prove valuable in counseling CN patients regarding reconstructive surgery.
