It is a component of a crucial shoulder muscle group, the rotator cuff. There are a few interesting additional muscles in the infraspinal region. In the literature they are called the infraspinatus superficialis, infraspinatus minor and infraspinatus accessory muscles. The infraspinatus minor muscle is described as a superficial muscle bundle running under the scapular spine. During routine anatomical dissection, an unreported variation of the infraspinatus minor muscle was found. It derived from the inferior surface of the scapular spine and the infraspinous fossa. It had two heads. The superior head inserted on the greater tuberosity of the humerus. The inferior head inserted on the tendinous part of the infraspinatus muscle. There was also an unusual fusion of the infraspinatus muscle with the teres minor muscle. In this paper we will discuss the anatomical and physiological relationships of this morphological variation.<\/jats:p>","DOI":"10.1007\/s00276-022-02999-4","type":"journal-article","created":{"date-parts":[[2022,8,12]],"date-time":"2022-08-12T18:03:00Z","timestamp":1660327380000},"page":"1305-1308","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["An unreported infraspinatus muscle variation\u2014two-headed infraspinatus minor muscle and three-headed fusion with the teres minor muscle"],"prefix":"10.1007","volume":"44","author":[{"given":"Krzysztof","family":"Koptas","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nicol","family":"Zielinska","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
