This article is a case report of a resection of symptomatic talocalcaneal coalition. A 26-year-old man presented with hindfoot pain and paresthesia of the medial plantar nerve region of 5 years’ duration. Plain radiographs revealed talar beaking, and computed tomography showed the area of coalition measured 44% of the area of the posterior facet. Conservative treatment with an arch support and oral anti-inflammatories for 2 months prior to operation had not given any improvement. At operation, a 1.5×1.5 cm ganglion was visible, which impinged on the medial plantar nerve. We excised the ganglion and talocalcaneal coalition. At the postoperative follow-up examination at 8 months, the patient was asymptomatic, and the result was satisfactory. The indications for resection of a talocalcaneal coalition include failure of non-operative treatment, a coalition that is less than one-half of the surface area of the talocalcaneal joint, and the absence of degenerative arthritic change. The indications for arthrodesis of talocalcaneal joint include a coalition that is more than one-half of the surface area of the talocalcaneal joint or the presence of degenerative arthritic change.
