Endoscopic Technique with Posterior Percutaneous Fixation for Complex Thoracic Spinal Infections: A Retrospective Cohort Study
This retrospective cohort study of 39 patients demonstrates that combining endoscopic debridement with posterior percutaneous internal fixation is a safe and effective treatment for complex thoracic spinal infections, resulting in significant pain relief, normalization of inflammatory markers, stable spinal alignment, and successful bony fusion without surgical complications.

Imagine your spine as the central support beam of a skyscraper, holding up the entire structure of your body. Sometimes, a nasty invader—like a bacteria or a fungus—decides to move into the joints between the bricks (the vertebrae) of this beam. This is called a spinal infection. It's like termites eating away at the wood; it causes the beam to rot, become weak, and eventually collapse, leading to terrible pain and potentially crushing the electrical wires (your nerves) running through the building.
Usually, doctors try to fight these invaders with strong medicine, like antibiotics, hoping to clean up the mess without touching the building. But sometimes, the invaders are too strong, or the damage is too deep, and the medicine isn't enough. When that happens, surgeons have to step in. The old way of doing this was like a demolition crew: they would cut a huge hole in the side of the building (a big open surgery) to scrape out the rot and bolt new beams in place. While effective, this method is messy, leaves a huge scar, and takes a long time to heal. Recently, surgeons have been trying "minimally invasive" techniques, which are more like using a tiny camera and a long, thin tool to fix the problem through a small keyhole. But for infections in the middle of the chest area (the thoracic spine), it's been tricky to get a good view and clean everything out without opening up the whole chest.
This study, led by a team from Shandong Provincial Public Health Clinical Center, decided to test a clever new combination: using a high-tech camera system to clean out the infection from the front, while simultaneously bolting the spine together from the back through tiny holes. They wanted to see if this "two-pronged" approach could fix complex, stubborn infections in the chest spine without the massive trauma of traditional surgery.
The researchers looked back at the records of 39 patients who had these tough infections and hadn't gotten better with medicine alone. These patients were a mix of ages, from 27 to 78 years old, and their infections were caused by various germs, with tuberculosis being the most common culprit. The team used a special endoscopic technique (a camera and tools inserted through small cuts) to reach the infected area in the chest, scrape away the rotting bone and pus, and drain the abscesses. At the same time, they used a posterior percutaneous fixation method, which means they went through the back and inserted metal screws and rods through tiny punctures to hold the spine steady while it healed.
The results were quite promising. Before the surgery, the patients were in significant pain, with an average pain score of 7.41 out of 10. Just one week after the operation, that number dropped to 3.15, and by one month, it was down to a nearly painless 0.46. The body's "fire alarms" (inflammatory markers like CRP and ESR), which were screaming loudly before the surgery, calmed down significantly within three months for most patients.
Perhaps most importantly, the spine stayed strong. The team checked the angle of the spine to see if it was collapsing or curving more (kyphosis). They found that the curve barely changed at all, with an average shift of only -0.21 degrees, meaning the spine stayed straight and stable. Every single patient achieved some level of bone fusion, meaning the vertebrae grew back together into a solid unit. In fact, 22 patients achieved a perfect "Grade I" fusion, and no one had a failure where the bones didn't heal.
The study also looked at the "bad guys" causing the trouble. By taking samples before giving antibiotics, they successfully identified the specific germ in 34 out of 39 patients (an 87.18% success rate). This helped them target the treatment precisely.
Crucially, the paper reports that there were no major complications. No one had new nerve damage, no one got an infection at the surgery site, and no one needed to switch to a big open surgery later. The authors suggest that this method is a safe and effective way to handle these difficult chest spine infections, offering a less invasive alternative to the old "demolition crew" approach. However, they are careful to note that because this was a smaller study looking back at past cases, more large-scale research is needed to confirm these findings for everyone. But for now, it looks like this camera-and-screw combo is a winning strategy for keeping the spinal skyscraper standing tall.
