At Yonsei Orthopedic Clinic (Donghoon Advanced Limb Lengthening Reconstruction Institute : DALRI), our mission is more than just lengthening or straightening bones — it’s about transforming lives. We make our patients’ dreams come true, enhancing not only the length and shape of their limbs but also their overall function.

Limb lengthening and deformity correction are challenging specialties, but we take pride in our high-quality, world-class practice. We firmly believe in our leadership and excellence in this field.

Safety is our top priority. Since our founding in 2009, DALRI has upheld a zero-tolerance policy for compromising patient safety. This unwavering commitment is reflected in all aspects of our systems, facilities, and care protocols.

Inspired by the motto “CHANGE LIMB, NEW DREAM,” our global medical charity extends the gift of comfortable, effortless walking to patients worldwide — empowering them to live better lives and fulfill their forgotten dreams.
