Scarless waist contouring in Tysons Corner reshapes the lower ribcage without a single incision, using an ultrasound-guided technique called RibXcar (also known as rib remodeling or waist narrowing).
What Is Scarless Waist Contouring (RibXcar)?
RibXcar takes a fundamentally different approach to waist narrowing than older rib surgery techniques. Rather than removing bone, the procedure uses a percutaneous method to access the lower "floating" ribs, specifically the 10th, 11th, and 12th, through a tiny puncture guided entirely by real-time ultrasound. A specialized instrument called a piezotome then creates a controlled, partial-thickness fracture in each targeted rib, allowing it to shift inward into a narrower position.
Researchers tracking this technique across patients in Peru, Colombia, and Mexico used ultrasound to measure costal angle and waist circumference before treatment. Again, at the one- and three-month marks, finding the narrower measurements remained consistent throughout that window. Since no incision is involved, patients and providers alike often refer to the technique as "scarless," a meaningful contrast to traditional rib removal, which requires cutting through small incisions to physically excise sections of bone and cartilage.
