Preliminary Results of Primary Gastrocnemius-Soleus Recession for Midfoot Charcot Arthropathy

Background Treatment of Charcot arthopathy of the foot can be challenging. The goal of this investigation was to determine whether primary gastrocnemius-soleus recession could decrease rate of new ulcers, progression of deformity, and amputation in patients with Charcot arthropathy of the midfoot.Methods A retrospective chart review revealed 28 feet in 24 diabetic patients with radiographic evidence of Charcot arthropathy of the midfoot. They were treated with primary gastrocnemius-soleus recession. Eleven feet in 11 patients had concurrent plantar midfoot ulcers. Three feet in 3 patients were lost to follow-up. Twenty-five feet in 21 patients were followed for an average of 37 months postoperatively (range = 18-79).Results A favorable outcome was defined as healing of existing ulcers, no new ulcers, no obvious progression of deformity, and no amputation. Favorable outcomes were obtained in 22 of 25 feet (18 of 21 patients). Only one patient had a persistent ulcer after gastrocnemius-soleus recession. The other 10 patients with preexisting ulcers healed. Deformity of midfoot progressed in one patient, leading ultimately to transtibial amputation. Another patient developed a knee joint infection and had a transfemoral amputation at another institution.Discussion These preliminary data suggest that primary gastrocnemius-soleus recession is followed by a much lower rate of persistent, recurrent, and new ulceration than previously reported studies. Gastrocnemius-soleus recession seems to aid in the treatment of Charcot arthropathy of the midfoot.
