Ten adolescent patients with Charcot-Marie-Tooth disease (12 feet) were evaluated an average of 7 years, 7 months following triple arthrodesis (TA) for the treatment of cavovarus deformity. The TA was the primary or index bone procedure. At follow-up, five feet were plantigrade, asymptomatic, and radiographically fused at all three joints. Three feet were plantigrade and asymptomatic, but two had talonavicular pseudarthrosis and one had calcaneocuboid pseudarthrosis. Three feet were radiographically fused at all three joints, but in nonplantigrade positions and symptomatic. One foot required a revision TA. In general, TA offers adolescent Charcot-Marie-Tooth patients a stable plantigrade foot in the face of a progressive disorder. The residual deformity, revision, and pseudarthrosis rates are similar to those for adults. Postoperative pain was related to a nonplantigrade foot and not to the presence of pseudarthrosis. It is not known whether a nonplantigrade foot was a result of incomplete surgical correction or recurrent deformity due to progressive muscle imbalance.

Pseudarthrosis after failed tibiotalar arthrodesis was successfully treated surgically in nine of 11 patients between 1980 and 1987. The indication for the initial attempted arthrodesis was traumatic arthrosis in seven patients, traumatic arthrosis with osteonecrosis of the talus in two patients, degenerative arthrosis in one patient with cavovarus foot (Charcot-Marie-Tooth), and myelodysplasia with progressive valgus deformity of the foot and ankle in one. The surgical technique planned for revision arthrodesis provided firm coaptation of tibia to talus with internal fixation that maintained the foot at right angles to the tibia with the forefoot in neutral position. Seven feet in 11 patients were treated using a transfibular approach that allowed excision of fibrous tissue and sclerotic bone, decortication of the media malleolus, fixation of the tibia to the talus with cancellous screws, and onlay/inlay fibular graft. Of the remaining four patients, one was treated with medial compression plate, a second was treated using an anteromedial cortical graft, a third was treated by a combination of sliding anteromedial corticocancellous graft and tibiotalar compression screw, and a fourth was treated with tibiotalar compression screw. Clinical and roentgenographic union occurred in nine of 11 patients. One patient developed a painless, fibrous union and one patient with persistent pseudarthrosis had myelodysplasia and severe valgus deformity and required amputation. Adequate exposure was possible through the transfibular approach to provide cancellous bone opposition, to excise the pseudarthrosis membrane and sclerotic bone, and to remove necrotic segments of the talus. In addition, supplemental bone graft, internal fixation, and postoperative cast immobilization were also helpful in obtaining union.

Charcot-Marie-Tooth disease results in pes cavus or equinocavovarus deformity. An accepted surgical correction is triple arthrodesis of the foot. In a retrospective study of 45 Charcot-Marie-Tooth patients, two cases developed neuropathic ankle joint after triple arthrodesis. This procedure prevents mobility of the tarsal joint and consequently increases stress on the ankle joint. If coupled with decreased joint sensation, it may predispose the ankle to neuroarthropathy. This paper emphasizes joint position sense as an important consideration before triple arthrodesis or any other surgical procedure.

Charcot-Marie-Tooth disease is a complex group of motor and sensory disorders presenting with varying levels of deformity dependent on the chronology and specific subgroup of the disease. In this report, we discuss a 19-year-old man with Charcot-Marie-Tooth 1A, a progressive and aggressive form of hereditary sensorimotor neuropathy, with rigid forefoot and rearfoot deformity. The authors discuss the etiology, tests, and sequential surgical management of this condition, focusing on a triple arthrodesis including a closingwedge subtalar joint fusion and a dorsal closing wedge osteotomy of the first metatarsal.

Charcot-Marie-Tooth disease is a neuromuscular disorder that commonly results in a predictable pattern of progressive bilateral lower extremity weakness, numbness, contracture, and deformity, including drop foot, loss of ankle eversion strength, dislocated hammertoes, and severe cavus foot deformity. Late stage reconstructive surgery will be often necessary if the deformity becomes unbraceable or when neuropathic ulcers have developed. Reconstructive surgery for Charcot-Marie-Tooth deformity is generally extensive and sometimes staged. Traditional reconstructive surgery involves a combination of procedures, including tendon lengthening or transfer, osteotomy, and arthrodesis. The described technique highlights our early surgical approach, which involves limited intervention before the deformity becomes rigid, severe, or disabling. We present 2 cases to contrast our early minimally invasive technique with traditional late stage reconstruction. Charcot-Marie-Tooth disease affects different muscles at various stages of disease progression. As 1 muscle becomes weak, the antagonist will overpower it and cause progressive deformity. The focus of the early minimally invasive approach is to decrease the forces that cause progressive deformity yet maintain function, where possible. Our goal has been to maintain a functional and braceable foot and ankle, with the hope of avoiding or limiting the extent of future major reconstructive surgery. The presented cases highlight the patient selection criteria, the ideal timing of early surgical intervention, the procedure selection criteria, and operative pearls. The early minimally invasive approach includes plantar fasciotomy, Achilles tendon lengthening, transfer of the peroneus longus to the fifth metatarsal, Hibbs and Jones tendon transfer, and hammertoe repair of digits 1 to 5.

Cavovarus deformity can be classified by the severity of malalignment ranging from a subtle and flexible to a severe and fixed cavovarus deformity of the foot.In the mild cavovarus foot, careful clinical assessment is required to identify the deformity.Weight-bearing radiographs are necessary to indicate the apex of the deformity and quantify the correction required.Surgery is performed when conservative measures fail and various surgical procedures have been described, including a combination of soft-tissue releases, tendon transfers and osteotomies, all with the aim of achieving a plantigrade and balanced foot.Joint-sparing surgery is the best option in flexible cavovarus foot even in Charcot-Marie-Tooth (CMT) disease (peroneal muscular atrophy).Arthrodesis is indicated in severe rigid cavus foot or in degenerative cases.
