Introducción: La precisión en la inclinación de las osteotomías metatarsales es clave en cirugías mínimamente invasivas (CMI) del pie. Las técnicas quirúrgicas pueden afectar los resultados postoperatorios. Este estudio evalúa la efectividad de un inclinómetro digital integrado en el motor de corte, comparando la precisión angular de osteotomías metatarsales, con y sin inclinómetro en especímenes cadavéricos y esqueletos de resina.
Material y métodos: Se realizaron 87 osteotomías metatarsales en especímenes cadavéricos y esqueletos de resina, divididos en dos grupos: sin inclinómetro y con inclinómetro. La precisión angular fue medida con radiografías y analizada mediante software. Las diferencias se evaluaron con pruebas t de Student.
Resultados: En el estudio con modelos esqueléticos de resina, los cortes realizados con inclinómetro mostraron una precisión significativamente mayor que los realizados sin él (p = 0,04), con una menor variabilidad angular. Sin embargo, en el estudio cadavérico, las diferencias entre los grupos no alcanzaron significación estadística (p = 0.42), lo que podría atribuirse a la mayor variabilidad y el pequeño tamaño de la muestra en este grupo.
Conclusiones: El uso del inclinómetro digital mejora la precisión en osteotomías metatarsales, especialmente en modelos esqueléticos. En especímenes cadavéricos, los tejidos blandos podrían haber afectado los resultados. Los inclinómetros en cirugías CMI pueden reducir la variabilidad entre operadores y mejorar los resultados postoperatorios. El inclinómetro digital es prometedor para aumentar la precisión en osteotomías metatarsales, aunque se requiere más investigación en especímenes cadavéricos para confirmar su eficacia clínica.

Surgical techniques can impact postoperative outcomes. This study evaluates the effectiveness of a digital inclinometer integrated into the cutting motor, comparing the angular accuracy of metatarsal osteotomies with and without the inclinometer in cadaveric specimens and resin skeletons.
Materials and methods: A total of 87 metatarsal osteotomies were performed on cadaveric specimens and resin skeletons, divided into two groups: without inclinometer and with inclinometer. Angular accuracy was measured using X-rays and analyzed with software. Differences were assessed using Student’s t-tests.
Results: In the study using resin skeletal models, cuts performed with the inclinometer showed significantly greater accuracy than those performed without it (p = 0.04), with less angular variability. However, in the cadaveric study, the differences between the groups did not reach statistical significance (p = 0.42), which could be attributed to greater variability and the small sample size in this group.
Conclusions: The use of a digital inclinometer improves accuracy in metatarsal osteotomies, especially in skeletal models. In cadaveric specimens, soft tissues may have affected the results. Inclinometers in MIS can reduce variability between operators and improve postoperative outcomes. The digital inclinometer shows promise for increasing precision in metatarsal osteotomies, although further research in cadaveric specimens is needed to confirm its clinical effectiveness.es.
