Unilateral two-headed extensor digitorum longus muscle: atypical configuration and clinical implications.

This report describes a new configuration of the extensor digitorum longus (EDL) with two heads and two main tendons divided into four slips. During routine cadaver dissection, unilateral (right) EDL muscle belly and tendon variations were identified. The morphometric measurements of the EDL were conducted using Image J software.

A case report of bilateral atypical origin of pectoralis minor.

Purpose: In the existing literature, various insertion variations and classifications for the Pectoralis Minor (PMi) muscle have been reported. However, there is limited information on inferior origin variations of the PMi muscles and a certain classification is lacking.

Case Presentation: During routine cadaver dissection of an adult male, variations in the origin of the bilateral PMi muscles were identified.
