Division of Orthopaedic Surgery

Our division performs surgical procedures on patients with congenital and developmental disorders of the extremities. We also deal with trauma and acute inflammation diseases in the extremities in cooperation with the emergency doctors at the hospital.

Planning your visit (for patients)

Medical services

Four certified orthopaedic surgeons and several fellows treat patients in our division. Two of our orthopaedic surgeons are also certified hand surgeons.

Diagnosis and treatment policy

Our policy is to ensure that all children with disorders of the extremities have access to effective diagnostics and therapy in order to improve limb function and enhance quality of life.


Our expertise encompasses the treatment of deformities and dysfunction of the upper and lower extremities listed below, using standard and advanced techniques such as bone lengthening with Ilizarov devices or unilateral elongation devices, free vascularized bone transfers, muscle transfers with neurovascular pedicles as well as tendon transfers.

Disorders of the upper extremities

We have treated a variety of congenital differences and post-traumatic deformities since the NCCHD opened in 2002.

Congenital differences of the hands, wrists, forearms and elbows

Polydactyly, Syndactyly, Radial ray deficiency (including Thumb hypoplasia), Radioulnar synostosis, Madelung's deformity, Macrodactyly, Cleft hand, Camptodactyly, Clinodactyly, Constriction band syndrome, Arthrogryposis, etc.
For example, we do thumb-preserving surgeries for Thumb hypoplasia, depending on the severity. (URL:

Clinical trial

We are conducting a clinical trial for prosthetic hands and for ultrasound diagnosis for congenital hand differences and pediatric traumas under approval by clinical research ethics review board at NCCHD.

Fellowship Program

We welcome international fellows from all over the world. The fellows can learn pediatric hand (congenital differences and traumas) as well as general pediatric orthopaedics. In addition, the fellows can be exposed to the clinical cases and surgeries, and have opportunities to participate in weekly conferences and rounds, and discuss any cases with us. Our division has many publications /presentations in international or domestic journals/scientific meetings. The fellows have opportunities to write scientific papers and have presentations, depending on their own motivation.

If you have any questions about the international fellowship program, please do not hesitate to contact us.
