RESUMEN
Background: Knowing the anatomy of the ribs is crucial for understanding various rib procedures. The present study is aimed at describing radiological measurements and ratios of 83 Latin American patients undergoing thoracoabdominal computed tomography (CT). Methods: A total of 83 thoracoabdominal computed tomography scans of women aged 18-35 conducted at a medical center in Lima, Peru, were reviewed from January 2022 to January 2023. The resulting measurements and ratios were used to calculate frequency distributions. All data were stored in a Microsoft Excel database and analyzed using statistical analysis software SPSS version 28. Results: Ratios and measures of the tenth, eleventh, and twelfth ribs are shown in the different tables, and costal characteristics with an adequate statistical significance are defined. Conclusions: Using radiological measurements and rib ratios, we were able to find key anatomical relationships with an adequate level of significance, which could help establish objective results in rib procedures.
RESUMEN
The gluteal region remains the preferred site for fat grafting. However, the transition from the gluteal region to the thighs has not been well studied. This study aimed to describe an echographic guidance hamstring volumization procedure (Hv-FAT) as a complement to body contouring surgery. Methods: Hv-FAT was performed in 19 patients from four countries (Peru, Argentina, Brazil, and Mexico) from May to June 2022 by four surgeons trained in soft-tissue ultrasound and in the aforementioned technique. All the patients met the following criteria: age older than 18 years and younger than 60 years; a body mass index of 30 kg/m² or less, and a surgical risk score of 2 or less, according to the Goldman index. Results: A total of four men and 15 women were included in this study, whose ages ranged from 22 to 58 years (mean: 36.37 years). After fat grafting, on average, the thickness of the right biceps femoris increased by 54.07%, maintaining 95.02% of this thickness one month postoperatively, whereas the thickness of the left biceps femoris increased by 46.57%, maintaining 94.86% of this thickness in the same postoperative period. In turn, the right semitendinosus muscle thickness increased by 181.90%, maintaining 97.42% of this thickness, whereas the left semitendinosus muscle increased by 111.90%, maintaining 95.29% of this thickness 1 month postoperatively (P < 0.0001). Conclusion: Hv-FAT is an effective and reproducible procedure for volumizing the biceps femoris and semitendinosus muscles, maintaining significant results one month postoperatively.
