How Children’s Hospital Boston approaches thumb duplication
The skilled experts in our Orthopedic Center’s Hand and Orthopedic Upper Extremity Program and our Plastic Surgery Department’s Hand and Microsurgery Reconstructive Program have treated thousands of babies and children with finger and hand problems, from simple to complex. We can provide your child with expert diagnosis, treatment and care—as well as the benefits of some of the most advanced clinical and scientific research in the world.
Our Orthopedic Center is recognized as the preeminent center for the care of children and young adults with a wide range of developmental, congenital, neuromuscular, sports related, traumatic and post-traumatic problems of the musculoskeletal system.
As one of the largest pediatric plastic surgery centers in the United States, our Department of Pediatric Plastic Surgery provides comprehensive care and treatment to children with a wide variety of congenital and acquired conditions, including finger and hand anomalies.
The Hand and Orthopedic Upper Extremity Program provides comprehensive care involving occupational and physical therapy, splinting, casting and reconstructive surgeries for infants, children and adolescents with complex congenital, neuromuscular, sports-related oncologic and traumatic upper limb conditions.
The specialists in the Hand and Reconstructive Microsurgery Program at Boston Children's are experts in the management of congenital and acquired hand deformities. We recognize the social elements involved in pediatric hand surgery, so an essential part of these operations has been making the child's hand as symmetrical as possible with his unaffected hand.
