Background: An attractive waist–hip ratio leads to a favorable aesthetic appearance in women and can be achieved through the osteo remodelación ultrasónica simplificada (ORUS) technique, which consists of the controlled fracture of the floating ribs through a small incision in the back based on an umbrella’s functioning (open-semiclosed). Methods: The ORUS technique was performed on 120 patients between 18 and 50 years of age. Patients were grouped according to the surgical procedure performed: ORUS (11 patients), ORUS + liposuction (n = 87), and ORUS + abdominoplasty (n = 22). Demographic and clinical preoperative and postoperative data were recorded in all patients included. Measurements of waist–hip index and body mass index were done in centimeters, and at 90 days, a computed tomography with 3-dimensional reconstruction was indicated. Results: The surgery time depended on the procedure and varied from 30 minutes in the ORUS procedure to 180 minutes when it was combined with an abdominoplasty. A waist reduction was achieved with median preoperative measurements ranging from 89.0–110.0 to 65.0–69.0 cm depending on the procedure. The size of the incision did not exceed 1.2 cm, and only 2 patients had symptomatic atelectasis. The median total Body-QoL score ranged between 97 and 99 points from a maximum of 100 points. Conclusions: The proposed ORUS technique achieved a waist and waist–hip index reduction with minor complications, a minimum scar, and a high satisfaction level.
