Lack of knowledge of variability in human morphology and its magnitude compared to normal anatomy may have significant clinical consequences. Accurate knowledge of anatomical variations provides important information in medico‐legal issues, forensic interpretation, diagnostics, imaging and patient management including surgical procedures. It has been hypothesized that a substantial proportion of clinical malpractice is attributed to ignorance of anatomical variations. Therefore, this study aims to assess the variations of metopic suture, sacral foramen and biceps brachii muscle in twenty‐four cadavers used for dissection as part of Gross anatomy course. The study was conducted in five medical schools in Ethiopia in 2015/2016 years. Critical observation, careful dissection and imaging were done accordingly. Our results show a complete persistence of metopic suture in 4.2 % of frontal bone, and the existence of five anterior and posterior sacral foramina in 4.0 % of sacral bone and biceps brachi with three heads of origin in 2.1 % of brachium. Altogether, the findings show the existence of anatomical variants of clinical importance that need special consideration in the diagnosis and treatment of this diversified population of Ethiopia with different socio‐economic background and geographical origin.
