    We recorded with this study that the EPL muscle and its tendon show a few anatomical variations. Any accessories tendons either the absence of this muscle or its tendon was found. In all preparation the passage of the tendon through the third osteofibroses compartment, crossing on the ERBC and ERLC going to the thumb was seen. The change of the tendinuous trajectory, deviating itself to the radial direction in one of the preparations was checked (1,6%). The partial duplication of the proximal tendon to the metacarpophalangeal joint (AMP) was seen in three observations (4,8%), one bilateral and distal to the articulation in five (8,3%), 2 bilaterally. The bone insertion at the base of distal (BFD) phalanx in all observations were found. During its passage through metacarpophalangeal joint we recorded its insertion in the joint capsule in 14 observations (23,3%), however the bone insertion there was not observed in this place.. The most common pattern about this (EPL) extensor pollicis longus muscle was the presence of a tendon, passing through the osteofibroses dorsal of wrist compartment with a bone insertion at the base of distal pollicis phalanx.
