About this Scientific Article

Charcot-Marie-Tooth disease (CMT) is a heterogeneous group of inherited peripheral neuropathies characterized by progressive degeneration and dysfunction of peripheral nerves.1 It affects both motor and sensory nerves, leading to muscle weakness, sensory loss, and other neurological abnormalities.2 In the most common form of CMT, pes cavus is the most prevalent foot deformity.3 However, in some individuals with CMT, progressive collapsing foot deformity (PCFD) can also occur due to muscle imbalances and weakness.4 Progressive collapsing foot deformity (PCFD), historically known as adult-acquired flatfoot deformity (AAFD) is a condition characterized by various degrees of hindfoot valgus, midfoot abduction, and forefoot varus.5 Several conservative and surgical treatments have been described.6 In cases of severe deformity, gross instability, or arthritic joint, a medial column arthrodesis, which consists of a fusion of the talonavicular (TN), navicular-cuneiform (NC), and first tarsometatarsal (TMT 1) joint, can be indicated7. Here, we report a case of Charcot-Marie-Tooth disease with atypical progressive collapsing foot deformity (PCFD) and medial column osteoarthritis.
