Rib surgery could redefine waist narrowing in body contouring
NCT ID NCT07705295
First seen Jul 15, 2026 · Last updated Jul 16, 2026 · Updated 1 time
Summary
This study looks at a surgical procedure called rib osteotomy with stabilization to narrow the waist in people already planning body contouring surgery. Researchers want to see if it is safe and does not harm breathing function compared to standard care. Participants will have their waist size and satisfaction measured over six months.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
The study population will consist of adult male and female patients aged 18 to 45 years seeking elective waist narrowing through high-definition liposculpture at participating center in Bogotá, Colombia. Eligible participants must have a body mass index (BMI) ≤30 kg/m² and demonstrate prominent projection of floating ribs (ribs XI-XII) ≥7 cm on preoperative computed tomography (CT), making them anatomically suitable candidates for structural waist modification. All participants must present with normal baseline spirometry values (FEV1, FVC, and FEV1/FVC within predicted limits) to ensure adequate pulmonary reserve prior to intervention. Participants must be medically fit for elective surgery under general anesthesia and capable of providing written informed consent and completing patient-reported outcome measures, including the Body-QoL questionnaire. Exclusion criteria include prior thoracic surgery or trauma, rib agenesis, osteoporosis or metabolic bone disease, c
