A Case Report of Endoscopic - Assisted Sacroiliac Joint Fusion
This case report describes a 40-year-old female with chronic sacroiliac joint pain who achieved significant short-term pain relief and rapid recovery following endoscopic-assisted sacroiliac joint arthrodesis, suggesting the procedure is a promising minimally invasive alternative for refractory cases despite its steep learning curve and the need for further long-term validation.

Imagine your body is a complex machine, like a high-performance car. Most of the time, the parts move smoothly, but sometimes a specific joint gets stiff, rusty, or inflamed, causing a loud, grinding noise every time you try to drive. In the human body, one of these trouble spots is the sacroiliac joint. Think of this joint as the heavy-duty hinge connecting your spine (the main chassis) to your pelvis (the rear axle). When this hinge goes wrong, it can cause a deep, aching pain in your lower back and hips that feels like a constant, annoying engine knock. For decades, doctors have tried to fix this with "conservative" methods—like physical therapy, which is basically tuning the engine, or painkillers, which are like putting a muffler on the noise. But for some people, the engine is so broken that tuning doesn't work. That's when surgeons step in to weld the hinge shut, a procedure called fusion. Usually, this requires a big, open surgery, like taking the whole car apart to fix one bolt. But recently, a new, tiny tool has entered the garage: the endoscope. This is a super-thin, high-definition camera on a stick that lets surgeons see inside the joint without making a giant hole. The big question for the medical world is: Can this tiny camera do the heavy lifting of welding the joint shut as well as the big, old-fashioned tools, but with less damage to the car?
This paper tells the story of one specific attempt to answer that question. The authors, a team of surgeons from Chongqing Medical University, decided to try a brand-new, ultra-minimally invasive technique called "endoscopic-assisted fusion" on a single patient. They didn't just use a regular camera; they used a specialized single-hole approach (known as AUSS) that combines the clear vision of open surgery with the tiny incision of a keyhole surgery. The patient was a 40-year-old woman who had been suffering from severe pain in her lower back and right leg for 16 years. It was a long, frustrating journey where she tried everything from acupuncture to psychological counseling (because her pain was so mysterious, some people thought it was all in her head), but nothing worked. Her pain was so bad that her Visual Analogue Scale (VAS) score—a way to measure pain from 0 to 10—was an 8. She could barely stand for more than 10 minutes.
The surgeons decided to take a chance on this new endoscopic method. They made a tiny 2.2-centimeter cut in her back, just big enough to slide in the camera and special tools. Inside, they used the camera to clean out the rough, inflamed surfaces of the joint, harvested a small amount of her own bone to act as a "glue," and inserted a cage to hold the joint together. They then screwed in metal screws to lock everything in place. The whole operation was surprisingly quick and clean, with only 50 mL of blood loss—about the amount in a small juice box. The results were promising in the short term. Just two weeks after the surgery, the patient's pain score dropped from an 8 to a 3. She could sit, stand, and even walk around for a few minutes without the crushing pain she had lived with for over a decade. The X-rays and CT scans showed that the screws and the cage were sitting exactly where they were supposed to be, holding the joint tight.
However, the authors are very careful not to call this a magic bullet. They explain that this was just one case, a single story, and not a big study with hundreds of people. They admit that this new technique has a "steep learning curve," meaning it's like trying to perform delicate surgery with a pair of chopsticks instead of a scalpel; it requires a surgeon who is already an expert in both spinal surgery and endoscopic tools. They also point out that the patient had some unusual immune system markers that weren't fully understood, and they aren't sure if those will affect how well the bone fuses in the long run. While the short-term pain relief was excellent, the paper suggests that we can't say for sure if this method will work for everyone or if the pain will stay gone for years. The surgeons conclude that while this endoscopic approach looks like a viable, less painful option for very specific, tough cases, it needs more testing and longer follow-up (1 to 2 years) to prove it's safe and effective for the long haul. For now, it's a fascinating, hopeful experiment, but not a solved problem.
