A “controversial” cosmetic procedure that involves altering the lower ribs to create a narrower-looking waist is gaining attention online, with experts warning that the trend comes with important surgical risks.
Dr. Anil Rajani recently discussed rib remodeling in a video, explaining that the procedure involves intentionally changing the position and structure of the lower ribs for cosmetic purposes.
“This is called rib remodeling and yes, surgeons intentionally fracture or weaken the lower ribs [to] reposition them inward,” Rajani said.
The goal is to create a more tapered waistline by changing the architecture of the rib cage rather than simply removing fat or tightening skin.
“And this is all to narrow the waist and yes there are published studies showing it can work,” Rajani continued.

What Is Rib Remodeling?
Rib remodeling is a form of cosmetic body contouring designed to reduce the appearance or circumference of the waist. Unlike traditional rib resection, in which portions of ribs are removed, newer remodeling techniques can involve controlled fractures or weakening of the lower ribs before repositioning or stabilizing them.
A 2026 systematic review and meta-analysis published in Aesthetic Plastic Surgery examined four studies involving 318 patients and found that rib remodeling without rib removal was associated with an average waist reduction of about 8.6 centimeters three months after surgery. However, the researchers noted that the available evidence remains relatively limited.
Another systematic review found that studies of cosmetic rib resection and remodeling have used a variety of techniques and patient populations. While newer remodeling approaches appeared to have fewer complications than rib removal, the authors said the lack of long-term studies and randomized clinical trials makes it difficult to draw definitive conclusions about long-term safety and effectiveness.
The Risks Behind the Waist-Narrowing Trend
While some studies have reported relatively low complication rates, rib remodeling is still surgery involving the chest wall—and the ribs are located close to the lungs. Rajani emphasized that point when discussing the procedure.
“What does work mean?” he asked. “Let’s be clear: you’re intentionally changing the architecture of your ribcage for cosmetic reasons.”
“The lungs are right there,” he continued, noting that potential complications can include “poor healing, asymmetry” and “even a pneumothorax, a collapsed lung.”
Medical literature also documents pneumothorax and other complications as potential risks. A 2026 global survey involving 2,351 patient records reported an overall complication rate of 3.7%, while pneumothorax occurred in 0.17% of cases.
Other reported complications included problems with healing, burns, hyperpigmentation and pressure ulcers associated with postoperative corsets. A separate 2026 multicenter study of 3,805 patients undergoing one type of minimally invasive rib-remodeling procedure reported an average waist reduction of 11 centimeters at one year.
The researchers documented four cases of pneumothorax, one case of hemothorax and two cases of chronic pain associated with bicortical fractures.
Does Rib Remodeling Actually Work?
Research suggests that rib remodeling can produce measurable changes in waist circumference. But “working” cosmetically does not necessarily mean the procedure is risk-free—or that its long-term effects are fully understood.
One earlier study of 27 patients who underwent rib remodeling with stabilization reported waist reductions of approximately 12.1 centimeters at one month and 13 centimeters at three months.
Meanwhile, a 2025 systematic review of the broader literature concluded that rib remodeling and resection appear promising for waist improvement, but long-term effectiveness remains uncertain because most available research consists of relatively small or retrospective studies with limited follow-up.
The American Society of Plastic Surgeons has also noted that rib remodeling differs from rib removal and may preserve more of the rib cage's protective function.
However, its experts acknowledge that potential complications can include pneumothorax, long-term pain, asymmetry and failure of the bone to heal properly.
Why Experts Say Patients Need to Do Their Homework
As the procedure receives more attention on social media, the distinction between different rib-contouring techniques is important. Not every procedure marketed as “rib remodeling” involves exactly the same surgical approach.
Patients considering the procedure should discuss the specific technique being proposed, what happens to the ribs, how they are stabilized, expected recovery and the surgeon's experience with the operation.
The evidence also continues to evolve. A systematic review published in 2026 concluded that more high-quality research and longer follow-up are needed to establish the long-term safety and effectiveness of cosmetic rib remodeling.
Ultimately, while studies suggest that altering the lower ribs can produce a narrower waist, the procedure involves intentionally changing the body's skeletal structure for cosmetic purposes.
As Rajani's comments highlight, the potential aesthetic benefit needs to be considered alongside the possibility of complications involving bone healing, asymmetry and the lungs.
