Selective Nerve Block-Guided Unilateral Biportal Endoscopic Bilateral T10 Rhizotomy for Refractory Intercostal Neuralgia Caused by Cement Leakage after Percutaneous Vertebroplasty: A Case Report and Literature Review
This case report demonstrates that selective nerve blocks can effectively localize the symptomatic nerve root in cases of refractory intercostal neuralgia caused by thoracic cement leakage after vertebroplasty, enabling a successful outcome with unilateral biportal endoscopic bilateral T10 rhizotomy as a targeted salvage procedure.

Imagine your spine is like a towering skyscraper made of bone blocks, stacked one on top of another. Between these blocks are little rubbery cushions called discs, and inside the blocks, there are tiny tunnels where electrical wires (nerves) exit the building to send messages to your body. Sometimes, in older buildings, these blocks get weak and crack. To fix them, doctors can perform a "repair job" called vertebroplasty, where they inject a super-strong, quick-hardening glue (cement) into the cracked block to make it solid again. Usually, this works like a charm, stopping the pain. But sometimes, a little bit of that glue leaks out of the block and clogs the tiny tunnels where the nerves live. When that happens, it's like someone pouring concrete into a doorframe; the door (the nerve) can't open or close, and it starts screaming in pain. Figuring out exactly which door is clogged is tricky, especially if the leak happened in two or three doors right next to each other. This story is about a team of doctors who had to solve a very confusing puzzle involving a leaky glue job, a screaming nerve, and a high-tech camera to fix it without tearing the whole building down.
This paper tells the story of an 83-year-old woman who had just had her spine "glued" back together to fix two fresh cracks. The original back pain vanished instantly, but immediately after, she developed a new, terrifying pain: a burning, band-like ache wrapping around her ribs and down to her belly, rated as an 8 out of 10 on a pain scale. A CT scan (a super-detailed 3D X-ray) showed that the cement had leaked into the tiny tunnels on both sides of her spine at two different levels, right next to each other. The problem was, the scan couldn't tell the doctors which specific nerve was actually causing the screaming pain. Was it the nerve at the top leak or the one at the bottom leak?
To solve this mystery, the doctors didn't just guess. They played a game of "spot the culprit" using a technique called a selective nerve block. Think of this like temporarily unplugging a specific lightbulb to see if the room goes dark. First, they injected a tiny amount of numbing medicine around the top set of nerves. The pain didn't stop. Then, they numbed the bottom set of nerves. Suddenly, the pain vanished! This told them exactly which nerve was the troublemaker: the one at the lower level.
Since the pain was so severe and wouldn't go away with normal medicine, the doctors had to perform surgery. But they didn't want to do a big, open surgery that would cut through a lot of muscle and bone. Instead, they used a high-tech method called Unilateral Biportal Endoscopy (UBE). Imagine this as using two tiny keyholes instead of a giant door. Through one hole, they shined a bright, magnified camera light into the spine; through the other, they slipped in tiny surgical tools. They carefully cleared away just enough of the hard cement that was blocking their view, but they didn't try to scrape out every single speck of glue, which would have been too dangerous. Instead, once they could clearly see the "screaming" nerve, they made a very specific, irreversible decision: they cut the nerve root.
This might sound scary, but the authors explain that for this specific patient, the nerve was only carrying sensation to her skin, not power to her legs. Cutting it was like pulling the plug on a broken alarm system that wouldn't stop ringing. The result? The pain stopped instantly. When she woke up, the 8/10 pain was gone, replaced by a 0. Three months later, she was still pain-free, and her life was back to normal.
The paper suggests that while cutting a nerve is a last-resort, permanent fix, it can be a brilliant "salvage" option for very specific cases where the pain is unbearable, the exact nerve is known, and removing all the cement would be too risky. The authors are careful to say this isn't a standard cure for everyone; it's a specialized tool for a very rare, difficult situation. They emphasize that you can't just cut nerves because a scan looks bad; you need to be absolutely sure which nerve is the problem, which is why the "unplugging" test (the nerve block) was so important. This case shows that with the right tools and careful planning, even the most confusing spinal glue-leak puzzles can be solved without causing a disaster.
