Abstract

A 14-year-old student presented with a 2-year history of progressive left foot deformity. High elevated medial arch, hindfoot varus deformity and second to fourth claw toes were idenfied in the left foot without a familial history. Neurologic examinations showed left distal lower extremity weakness and bilateral increased deep tendon reflexes. MRI of whole spine demonstrated thickened filum terminale and spinal defect covered with pulled skin which findings consistent with tethered cord syndrome (TCS). He was referred to neurosurgery department and had a detethering operation of the spinal cord. Two years later, he underwent foot surgery because his foot deformity progressed despite the detethering operation. It is very rare for TCS to present with pes cavus as the only symptom, also in Korea. We suggest that TCS should be considered as one of the differential diagnoses associated with unilateral pes cavus in adolescence so as not to miss the proper period of surgery.
