The SAHZU Bone Center is at the forefront of diagnosis and treatment of difficult, complex and critical orthopedic diseases in China. In 1971, a novel transpositional replantation for a patient whose lower limbs were severely injured in a car accident was conducted at the Center.

It now has nine subspecialties, including trauma, spine, joint, bone tumor, foot and ankle, hand surgery, sports medicine, repair and reconstruction, and pediatric orthopedics.

Since the 1970s, the center has advanced the diagnosis and management of bone tumors. The osteosarcoma center at the Bone Center is responsible for standardized treatment. It regularly performs limb salvage surgery, hyperthermic isolated limb perfusion, and many other advanced surgeries with novel techniques such as upshifting of the proximal femur. It also performed the first minimally invasive lateral lumbar decompression fusion (CLIF) and pelvic tumor resection + superior femoral displacement + prosthesis reconstruction in China. SAHZU orthopedic surgeons are the first in Zhejiang province to carry out 3D printing artificial joint reconstruction technique for bone defect after bone tumor resection and the reconstruction of sacrum after total sacral resection due to sacral chordoma. Based on solid basic and clinical research, SAHZU orthopedic surgeons proposed the SAHZU Strategy of Reconstructive Ladder for degenerative spine diseases. The strategy recommends injection of type II collagen for early- and mid-stage degeneration to induce the differentiation of stem cells into nucleus pulposus cells, promoting biological reconstruction. For mid-to-late-stage degeneration, it suggests a micro-invasive lumbar interbody fusion technique along with a staging strategy and phase 2 assessment, all developed by SAHZU. This novel surgery technique is widely used not only in China, but also in the United States, Germany, Australia, Malaysia and so on.

The sports medicine team is also the bedrock of healthcare services including trauma management for the world swimming champions and their teammates.
