Treatment of the High Iliac Crest with Iliac Crest Reduction (XCREST)

The iliac crest is defined as the superior border of the ilium or iliac bone and serves as an insertion point for various muscles, ligaments, and fasciae. The iliac crest should be prioritized if a more harmonious body is sought, since, by performing a fat transfer above the gluteus medius muscle area, the gluteus medius is volumized and a high and large buttock is obtained, which is not always aesthetically beautiful. Describe a safe, crest-treating technique (XCREST) oriented to decrease the iliac crest to achieve a more harmonious transition from the waist to the hip. In this study, the sample consisted of 200 female patients. Measurements were taken of the waist, the distance between the iliac crest and the trochanter and the distance between the last palpable rib and the iliac crest in the preoperative stage, in the immediate postoperative stage and six months later. A reduction in the mean waist measurement was found, being 83.11 cm preoperatively, 72.31 cm in the immediate postoperative period and 72.06 six months after the operation. Of the 200 cases, the average distance between the last palpable rib and the iliac crest increased by 3.8 cm. Ten percent of the patients presented complications related to pain for less than two months, which were duly treated. The XCREST technique effectively reduces the waist diameter and improves the aesthetic appearance at the sixth postoperative month, evidencing a better transition between the waist, hip, and buttocks.
