| Summary: | Objective: To evaluate the efficacy of surgical treatment to correct the main deformities associated with flexible cavovarus foot due to Charcot-Marie-Tooth disease. Methods: Fifteen patients (18 feet) with flexible cavovarus feet due to Charcot-Marie-Tooth disease were evaluated and underwent surgery between 2000 and 2015. We used a “triple surgery” protocol: a combination of plantar fasciotomy, valgus-inducing osteotomy of the calcaneus, and lengthening osteotomy of the first metatarsal. After a mean follow-up time of 105 (48 to 198) months, we developed a numerical scale to assess the main aspects of patient complaints: pain (3 points), function (3 points) and deformity (4 points). The scale considered the results of the visual analog pain scale, the American Orthopedic Foot and Ankle Society Scale, and the Coleman block test, as well as clinical and radiographic evaluation of gait and cavovarus deformities. Results: According to the numerical scale, the results were considered satisfactory in 15 of the 18 feet (84%) and unsatisfactory in 3 (16%). Conclusion: In the medium term, the “triple surgery” protocol proved efficient for correcting cavovarus deformities, providing functional improvement while preserving mobility without pain complaints. In the final analysis, through the “triple surgery” protocol, early indication for arthrodesis can be avoided, postponing sacrifice of the hindfoot joints.
