Flander, Miha (author), Kunc, Robert (mentor), Trajkovski, Jovan (comentor)

Določanje prečnega prereza ligamentov je ključno za razumevanje mehanskih lastnosti in stabilnosti kolenskega sklepa. To delo vključuje pregled literature, litje, merjenje, uporabo geometrijske aproksimacije in 3D-skeniranje pozitivov prašičjih ligamentov. Primerjava metod je potekala na osnovi analiz pozitivov iz keramičnega praha, kar omogoča natančne in časovno neodvisne meritve. Rezultati kažejo, da izbrana metoda geometrijske aproksimacije s kljunastim merilom ni primerna za natančno merjenje prečnega prereza, medtem ko je 3D-skeniranje hitro, zanesljivo in natančno za določevanje prečnega prereza ligamentov.

• Title: A comparison of methods for measuring ligament cross-section based on an analysis of a positive from silicone mold negatives

Abstract

Determining the cross-sectional area of ligaments is crucial for understanding the mechanical properties and stability of the knee joint. This work includes a literature review, casting, measuring, geometric approximation, and 3D scanning of porcine ligament positives. Method comparison was based on analyses of positives made from ceramic powder, enabling precise and temporally independent measurements. The results indicate that the chosen casting method maintains accuracy and integrity of samples, while 3D scanning is fast, accurate, and reliable for measuring ligament cross-sectional areas.
