Ⅰ. What is the hardest bone surgery?

Scoliosis Correction Surgery

Realigning the deformed spine requires an incision up to 40 cm, and the vertebrae are stabilized with over 20 metal screws. This requires extremely high precision (the distance between the screws and the nerves is only 1.5 mm). Axial Tumor Resection Surgery for axial tumors of the spine, pelvis, and other axial bones is extremely risky due to their complex anatomy, rich blood supply, and proximity to important nerves and blood vessels. En bloc resection of the tumor and restoration of stability are essential.

Revision Total Hip/Knee Surgery

Revision surgery after multiple arthroplasties often results in severe bone defects, requiring precise reconstruction using 3D-printed prostheses and intelligent navigation systems.

Internal Fixation of Pelvic Fractures

As a load-bearing structure, fracture reduction of the pelvis requires addressing the irregular bone surfaces and dense surrounding blood vessels, leading to a high risk of intraoperative bleeding.

Total en bloc spondylectomy (TES)

This procedure is used for malignant spinal tumors. It requires complete tumor removal within a limited field of view while protecting the spinal cord and major blood vessels.

These procedures require multidisciplinary collaboration and are highly demanding on physician skills, equipment, and perioperative management.

Ⅱ. What is the use of Orthopedic Bone Drill?

An Orthopedic Drill bit is a specialized tool used in orthopedic surgery to drill, cut, or grind bones. Its core function is to provide precise bone access to implants, such as plates and screws, assisting in fracture reduction, joint replacement, or bone tissue repair. It combines high-speed rotation with controlled pressure to ensure precise operation and minimize damage to surrounding tissues.

The main applications of Orthopedic Drill Bits

Bone drilling

Orthopedic drills are most commonly used to drill holes in bones to create channels for internal fixtures such as screws and nails. For example, in fracture reduction surgery, the Surgeon Drills holes on both sides of the fracture and then secures the bone fragments with screws to ensure alignment during the healing process.

Bone surface trimming and cutting

In joint replacements, such as hip and knee replacements, drills are used to cut or trim irregular bone surfaces to make the artificial joint fit the patient's anatomy better. Additionally, in tumor resection or deformity correction surgery, drills allow for precise removal of lesions or excess bone tissue.

After the bone canal is enlarged and polished drilled, in some cases, the hole diameter needs to be enlarged or the edges of the hole sanded to prevent bone cracks or implant displacement. For example, in spinal fusion surgery, the bone passage of the pedicle screw needs to be enlarged to accommodate the diameter of the screw.
