title: Valgus toe deformity of fourth proximal phalanx due to osteochondroma treated with closing wedge osteotomy.
abstract: Osteochondroma is the most common benign tumor of all benign and primary bone tumors. It rarely occurs in the proximal phalanx of the lesser toe. The treatment of osteochondroma usually consists of simple resection. However, if other deformities remain, added procedures may be considered. We report a case of a valgus toe deformity of the fourth proximal phalanx due to osteochondroma. The patient was a 21-year-old man who noticed a valgus deformity of his fourth toe over 10 years earlier. He began to experience pain in his fifth toe because of crossover of the fourth toe when wearing formal shoes. Although resection of osteochondroma was performed, the valgus deformity was not sufficiently corrected. Therefore, closing wedge osteotomy of the proximal phalanx was performed at the same time. A good outcome was achieved for this patient.
