Rib Remodelling: The Evidence & Statistics
Rib remodelling is the only procedure that reshapes the skeletal frame of the waist — and it is backed by a genuine, growing body of published research: international case series, systematic reviews and, as of 2025, a pooled meta-analysis. Across that literature the story is consistent — meaningful, measurable waist reduction with low complication rates in modern series. This page sets out the research in full, every figure cited to its source.

The pattern across the literature is consistent: meaningful, measurable waist reduction, high reported satisfaction, and low complication rates in modern remodelling series — a materially better profile than the historical rib-resection approach the technique replaced.
The research
The studies
PRS Global Open, April 2026. A global survey of rib remodelling practice that aggregated 2,351 cases (2018–2024) — by a wide margin the largest body of outcome data assembled for the procedure. Critically, serious complications were rare: major complications such as pneumothorax occurred in just 0.17% of cases. Because it pools surgeon-reported cases rather than following a single prospective cohort, it is best read as a broad real-world snapshot rather than a controlled trial — but at this scale it is a meaningful signal that serious complications are uncommon.

Published in Aesthetic Plastic Surgery (Springer), 2025. Pooled four studies totalling 318 patients (98.1% women; mean age 32.7; mean BMI 22.4). Mean waist reduction 8.59 cm at three months; satisfaction 94.89/100; zero pneumothorax and zero infections across the pooled cohort; skin burns 0.57 per 100; asymmetry 1.85 per 100, largely associated with lapses in corset wear. Level II evidence.

Plastic and Reconstructive Surgery — Global Open, 2021: the paper that established waist narrowing without removal of ribs. 93 patients treated with the greenstick (controlled incomplete fracture) method; the subgroup with six-month follow-up averaged around 8 cm of reduction. The series also reported that 14% of patients elected a secondary procedure to refine their correction — an early-technique figure that subsequent imaging-guided methods were developed to improve on.

PRS Global Open, 2024. 49 women treated with ultrasound-guided percutaneous remodelling: mean reduction 8.70 cm at six months with the standard technique, and 17.04 cm in a selected group treated with the more extensive false-to-floating conversion variant. This series established the modern minimal-access, imaging-guided form of the procedure.

PRS Global Open, 2025. The largest published single series to date: 220 women treated with ultrasound-guided monocortical (greenstick) remodelling. Mean waist circumference fell from 77.9 cm to 66.2 cm at six months, and 93% had no major complications — the minor complications recorded being temporary discomfort and occasional small skin marks from the ultrasonic instrument. It is the strongest single-cohort evidence available for the modern minimal-access technique.

Plastic and Reconstructive Surgery, February 2025. 27 patients; ribs repositioned and fixed with titanium plates. Reported 12–13 cm waist reduction and 6–8 cm at the hip line, without prolonged corset wear — demonstrating how far the technique family has developed, and the trade-offs (hardware, larger access) that come with the larger published reductions.

Two systematic reviews take the wide view. An 11-study review (~738 patients, Revista Brasileira de Cirurgia Plástica) documents reductions of 6–13 cm across techniques. A further review (~549 patients, Sage) spans 5–17 cm across all technique generations — and highlights that the complications recorded in the literature (including the pneumothorax cases) cluster in the older resection cohorts rather than modern remodelling. Both reviews note the field’s evidence is still maturing: predominantly retrospective series with follow-up mostly to six months.

In context
Reading the evidence clearly
A few points of context help you weigh these figures the way your surgeon will in consultation:
Request a consultationThe mean average is your anchor. 8.59 cm is the pooled average; where you land depends on your anatomy — rib flare, torso shape, soft-tissue envelope — which is exactly why planning starts with your own CT.
Technique explains the range. The 6 cm and 17 cm ends of the published range are different operations on different anatomy. Your consultation establishes which technique, and which realistic range, applies to you.
Complication data favours modern technique. Zero pneumothorax and zero infections across the 318-patient pooled cohort reflect precisely what imaging guidance and bone-preserving technique were built to achieve.
One honest note on the state of the evidence: published follow-up runs mostly to six months, the studies are retrospective, and long-term data will continue to accumulate as it does for every surgical innovation. What exists today — several hundred published patients, consistent reductions, low complication rates and a Level II pooled analysis — is a solid, growing base. Like all surgery, rib remodelling still carries real risks, set out plainly on our Risks & Safety page.
