II. Internationally Leading Specialty Technologies​ 
(1) Spine Minimally Invasive Techniques​ 

Percutaneous Endoscopic Discectomy (Cervical/Lumbar):​

7mm incision, patients walk within 24 hours for rapid recovery.

UBE (Bilateral Channel Endoscopy) Technology:​

Wide field of view, large decompression range; separates observation and operation channels for minimally invasive pedicle screw/interbody cage placement.

Percutaneous Vertebroplasty (PVP/PKP):​

Treats osteoporotic fractures, relieves pain instantly, enables immediate mobilization. Uses 3D-printed coplanar templates​ for precise particle implantation.

Complex Spinal Deformity Correction:​

3D corrective techniques​ for severe scoliosis/kyphosis; halo-femoral traction​ gradually adapts blood vessels to stretching before corrective osteotomy, reducing intraoperative nerve injury risks.

World’s First Laparoscopic Artificial Disc Replacement:​

Pioneered by Professor Wang Wenjun’s team, enabling minimally invasive disc replacement for degenerative spinal diseases.

（2）Joint Surgery Techniques​ 
Personalized Joint Replacement:​

Hip, knee, and shoulder replacements using 3D-printed custom prostheses.

Femoral head replacement  completed in 30 minutes​ with minimal bleeding; patients walk within 7–8 hours post-op, reducing bed rest and complications.

Arthroscopic Surgery:​

Meniscus repair, ligament reconstruction, loose body removal, and lavage for sports injuries​ (minimal trauma, fast recovery).

Platelet-Rich Plasma (PRP) Injections:​

Promotes cartilage repair for knee osteoarthritis; tailored treatment plans (rehabilitation, medication, PRP) for early/mid/late-stage arthritis.

(3) Trauma and Microsurgery Techniques​ 
MIPO (Minimally Invasive Plate Osteosynthesis) for Limb Fractures:​

Protects blood supply, accelerates healing; minimal trauma, fewer complications.

Ilizarov Bone Transport Technique:​

Treats bone defects and limb deformities (especially for vasculitis and diabetic foot patients). Combines Ilizarov technology, traditional Chinese medicine, and functional exercises to heal nonunions, defects, and osteomyelitis.

Finger/Toe Replantation Success Rate >95%:​

Achieved via high-precision vascular/nerve anastomosis​ under advanced microscopy.

(4) 3D Printing and Navigation Technologies​ 
3D-Printed Personalized Customization:​

Preoperative 3D models simulate surgery; intraoperative O-arm navigation​ enables millimeter-precision operations.

3D-printed artificial vertebral bodies​ mimic human trabecular bone structure (porous design promotes bone cell ingrowth, enhances fusion stability; superior strength/elasticity vs. traditional grafts).

Smart-Driven Design:​

Project "Smart-Driven 3D-Printed Personalized Spine Surgery Products: Medical Simulation and Clinical Application" won the 2025 National Second Prize (Clinical Medicine/Public Health Direction)at the 4th National Simulation Innovation Application Competition.

(5) Stem Cell and Neural Repair Technologies​  
Stem Cell Therapy for Knee Arthritis:​

Intra-articular stem cell injections promote cartilage regeneration, reduce pain, and improve function. Stem cells differentiate into chondrocytes, secrete growth/inflammatory factors, and inhibit damage.

Umbilical Cord Blood Cell Therapy:​

Isolates hematopoietic and mesenchymal stem cells from umbilical cord blood, delivering them via intrathecal injection to spinal cord injury sites. These cells differentiate into neural-like cells, secrete neurotrophic factors, and create a "golden microenvironment" for repair.

Neural Modulation Technology:​

Implants microscopic interfaces in the spinal cord to transmit brain motor signals directly to lower limb nerves. Closed-loop spinal cord neural interface surgery adjusts signal intensity based on patient intent for precise control.

III. Advanced Equipment for Precision Medicine​ 
Equipped with world-class devices:

Imaging: 3.0T MRI, spine endoscopy system, arthroscopy, intraoperative nerve monitor, PET-CT, gamma knife, 128-slice CT, color Doppler ultrasound.

Critical Care:Multi-parameter monitors, ventilators, defibrillators.

Ensures visualized, precise diagnostics and surgery for complex orthopedic cases.

IV. Multidisciplinary Collaboration (MDT)  
Collaborates with anesthesia, rehabilitation, and imaging departments to create pain-free demonstration wards, promoting enhanced recovery after surgery (ERAS) and reducing hospital stays by over 30%. Specialized MDT teams for conditions like vasculitis and diabetic foot drive subspecialty innovation.

V. International Training and Academic Exchange

17 spine surgeons from the US, Germany, Japan, South Korea, Singapore, Australia, etc., through systematic clinical mentoring, surgical demonstrations, and theoretical lectures. This has promoted advanced minimally invasive spine techniques globally, enhancing the center’s international influence.

International students went to the ward to observe（2）

VI. Core Advantages Summary​ 
The Orthopedics and Spine Surgery Center is driven by technological innovation​ and patient-centered care, with four key strengths:

Precision Diagnostics:Personalized treatment plans via genotyping, imaging navigation, 3D printing, and navigation technologies.

Comprehensive Minimally Invasive Coverage:From spine to joint surgeries, ensuring minimal trauma and rapid recovery (patients often walk the next day).

Stem Cell and Neural Repair:Advanced therapies for nerve injuries​(e.g., stem cell knee therapy, umbilical cord blood treatment, neural modulation).

MDT Collaboration:Cross-disciplinary teamwork solves complex cases, creates pain-free wards, and accelerates recovery.

The center will continue advancing global cutting-edge technologies to optimize treatment, providing safer, more efficient, and personalized care for orthopedic patients in Changsha, Hunan, and beyond.

Mission:"Technology Leadership, Warm Service"– Delivering quality orthopedic care. Open to collaborations with domestic/international institutions to tackle complex orthopedic challenges.
