【 摘 要 】

BackgroundMorphological variations of the EHL concern mainly the accessory tendons and the site of their insertion. The aim of our study is to present a new classification of the EHL.MethodsClassical anatomical dissection was performed on 104 lower limbs (51 right, 53 left, fixed in 10% formalin solution).ResultsIn 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 - 1.9%).ConclusionThe EHL presents high morphological variability. Knowledge of particular types of insertion is essential for both clinicians and anatomists.
