condition is usually found in the hips, although there have been documented cases of certain individuals with it occurring in the arms and legs. The cause for the process to initiate is not well understood, only that it typically results from surgery or trauma. History Etymology and spelling Anconeus muscle is the anglicized form of the Latin expression musculus anconaeus, as can be found in the Nomina Anatomica as ratified in Basel in 1895 and in Jena in 1935. The anatomic Latin adjective anconaeus was written as anconeus in the subsequent edition of the Nomina Anatomica as authorized in 1955 in Paris, without any further explanation of this specific diphthong reduction. The following edition of 1961 specified its policy by stating that: All diphthongs should be eliminated. Although a selected number of monophthongizations was reverted, subsequent editions of the Nomina Anatomica and its most recent outing Terminologia Anatomica insisted on writing musculus anconeus. Despite the earlier preference of the Nomina Anatomica for anconaeus no ancient Greek form ἀγκωναῖος is attested. In modern Greek the expression ἀγκωνιαίος μυς is used, with the from anconaeus deviating adjective ἀγκωνιαίος. Anconaeus is derived from the ancient Greek noun, ἀγκών. 'Ακών can be translated as bend of the arm or elbow. The expression musculus anconaeus was translated into English as elbow muscle in 1907 in the English translation of the first edition of the Nomina Anatomica.
