The aim of our study is to present a new classification of the EHL.<h4>Methods</h4>Classical anatomical dissection was performed on 104 lower limbs (51 right, 53 left, fixed in 10% formalin solution).<h4>Results</h4>In the cadavers, three types of morphology (insertion and addidtional band) were observed. Type I, the most common type, was characterized by a single tendon that ends as an extensor hood on the dorsal aspect of the base of the distal phalanx of the big toe (57.7%). Type II was characterized by two distal tendons and was subdivided into three subtypes according to (A-29.9%, B-4.8% and C-5.7%). Type III was characterised by three distal tendons (two cases BMC musculoskeletal disorders310https://www.ebi.ac.uk/biostudies/studies/S-EPMC6607556biostudies-literatureA cadaveric study of the morphology of the extensor hallucis longus - a proposal for a new classification.PMC6607556Polguj MRuzik KTopol MPodgorski MOlewnik LfalseA cadaveric study of the morphology of the extensor hallucis longus - a proposal for a new classification.<h4>Background</h4>Morphological variations of the EHL concern mainly the accessory tendons and the site of their insertion.
