Surgical Considerations for Massive Tarsal Coalitions in Multiple Synostosis Syndrome: A Case Report.

Tarsal-carpal coalition syndrome is an autosomal dominant inherited condition characterized by fusion of the carpal and tarsal bones and foot deformity. Associated pain and/or gait disturbance are the main complaints. The deformity usually consists of varying degrees of hindfoot varus and forefoot supination. The treatment of these patients is mainly aimed at symptomatic relief. We performed a published data review of this condition and discuss our findings in the context of the case of a 10-year-old female with congenital varus deformity of both feet. The tarsal-carpal coalition syndrome has been included in the spectrum of heritable disorders related to mutations in the NOG gene. Deformity management should be customized to the patient's requirements, and satisfactory results are achievable with adequate rehabilitation. It is important to remember that surgery is only necessary for symptomatic relief and that patients with tarsal-carpal coalition syndrome should be followed up over time because the condition can evolve.
