Echo-guided Lower-back Sculpture and Volumization as a Complement to High-definition Liposuction (XPINE-FAT)

Area of Science:

• Plastic Surgery
• Aesthetic Medicine
• Body Contouring

Background:

• Limited knowledge exists regarding surgical techniques for improving lower-back aesthetics.
• Surgical interventions for lower-back appearance are not well-documented.

Purpose of the Study:

• To describe a novel high-definition liposuction technique.
• To detail the intramuscular grafting of erector spinae muscles (longissimus) for aesthetic enhancement.
• To evaluate the safety and efficacy of the XPINE-FAT procedure.

Main Methods:

• A cohort of 15 female patients (ages 25-48) underwent body contouring surgery.
• A low-back lipodefinition and echo-guided intramuscular fat graft of the erector spinae (longissimus) muscles were performed.
• Pre-operative and immediate post-operative measurements were collected and analyzed.

Main Results:

• Fat grafting to the erector spinae muscles (longissimus) resulted in significant immediate intramuscular thickness increase.
• Mean volume grafted was approximately 43-45 cm³ per side, increasing thickness by over 65% (P < 0.0001).
• Surgical times averaged 3.73 hours with hospitalization of less than a day.

Conclusions:

• The XPINE-FAT technique is a safe and effective method for enhancing lower-back aesthetics.
• The procedure leads to an immediate increase in the intramuscular thickness of the erector spinae muscles.
• No adverse events were reported during the study period, indicating a favorable safety profile.
