Background

Alexandre Arkader, MD, is a board-certified attending surgeon who specializes in treating children with bone tumors. He works with the Division of Orthopaedics and the Cancer Center at Children’s Hospital of Philadelphia.

Dr. Arkader is one of a handful of surgeons in the country with formal training in both pediatric orthopaedics and orthopaedic oncology. Additionally, he has a special interest in treating complex limb deformities, expertise in external fixation methods and other minimally invasive techniques for limb preservation and correction.

“The minute I started my orthopedic residency, I knew I’d go into peds ortho; I just love caring for children,” Dr. Arkader says. “The thought about taking care of oncology patients only came to me during my fellowship at CHOP Orthopaedics. The combination of both subspecialties – orthopaedics and orthopaedic oncology – lead to my desire to treat children with benign and malignant bone and soft tissue tumors, as well as perform limb salvage and reconstruction procedures for children with congenital and acquired conditions.”

“The ability to create such a positive impact in the care of these children, the possibility of combining all the principles in pediatric orthopaedic care and oncological principles to achieve the best outcome possible for the affected child is both challenging and inspiring,” Dr. Arkader adds.

Dr. Arkader joined CHOP after eight years at the Children’s Hospital of Los Angeles (CHLA) and Keck School of Medicine of USC. At CHLA, Dr. Arkader served as the Director of the Bone and Soft Tissue Tumor program, the Orthopedic Trauma Program, and the International Fellowship at the Children’s Orthopedic Center at CHLA.

Dr. Arkader earned his medical degree from F.T.E. Souza Marques in Rio de Janeiro, Brazil. He completed an internship in international medicine at the Hospital Santa Casa de Misericordia, and a residency in orthopedic surgery at the Hospital de Traumatologia-Ortopedia in Rio de Janeiro, Brazil.

In 2003, Dr. Arkader came to the United States to further his professional training. He completed a fellowship in pediatric orthopedics at Children’s Hospital of Philadelphia, and a second fellowship in musculoskeletal oncology at Memorial Sloan-Kettering Cancer Center in New York, NY.

Along with his clinical work, Dr. Arkader is also an active researcher. He’s published more than 80 peer-reviewed articles, many of which focused on musculoskeletal oncology and benign bone tumors, an area in which CHOP is a national leader in both experience and volume of patients successfully treated.

“We are 100% focused on pediatric care,” Dr. Arkader says. “I’m proud to work here with a team that is fully dedicated to achieving the best outcomes possible for all of our patients.”

Dr. Arkader has served as a national authority for numerous textbook chapters on pediatric musculoskeletal tumors. He has lectured in innumerous national and international meetings, and leads a biannual pediatric orthopedic course in South America. He participates in several study groups focused on research related to trauma and musculoskeletal infections and is an active reviewer for several medical journals. In addition, Dr. Arkader is a member of several national and international professional organizations including the Pediatric Orthopedic Society of North America, the American Academy of Orthopaedic Surgeons, the Musculoskeletal Tumor Society and the Children's Oncology Group.
