Why have this procedure done in China specifically?

China offers the same advanced tubular retractor technology and surgical techniques as Western centers at a significantly lower cost—approximately $14,500 compared to $50,000–$100,000 in the U.S. Chinese hospitals often have high-volume spine surgeons performing hundreds of TLIFs annually, which correlates with better outcomes. Combined with modern facilities and English-speaking coordinators, this makes China a reliable and cost-effective option for international patients.
