A Multiple Osteochondromas of Lower Limbs, Treatment with Total Hip Arthroplasty

1. Abstract

Osteochondromas also known as an osteocartilaginous exostosis, or simply as an exostosis, represent the most common bone tumor accounting for 20-50% of benign bone tumors and 9% of all bone tumors [1-3]. We report a 52-year-old case of multiple osteochondromas with hip dysplasia and subsequent degenerative arthritis. This is the first report of total hip arthroplasty (THA) for osteoarthritis secondary to multiple osteochondromas in China.
