Both layers showed considerable interindividual variability, ranging from thin and translucent to dense and collagen rich. There is an interposed fat layer between the superficial and deep fascial layer suggesting a potential sliding interface. The fascia forms a tubular sheath around the supraspinatus muscle, attaching to the margins of the supraspinatus fossa as well as the superior transverse scapular ligament, clavicle, and coracoid process. The deep layer is continuous with the subacromial bursa and the posterior origin of the supraspinatus muscle. In contrast, the superficial layer integrates into surrounding fascial systems, including connections to the fasciae of the levator scapulae and rhomboid minor muscles. Histological analysis identified neurovascular bundles within and traversing both fascial layers. A subset of nerve fibres showed substance P immunoreactivity, supporting a nociceptive role of the supraspinatus fascia.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The supraspinatus fascia is a complex structure rather than a passive wrapping. Its distinct two-layered architecture and substance P-positive innervation provide an anatomical basis for idiopathic scapular pain. Clinically, the deep layer\u2019s continuity with the subacromial bursa suggests that inadequate fascial release during subacromial decompression may lead to persistent symptoms. Finally, the superficial layer\u2019s connection to the \u201clevator-rhomboid-minor-fascia\u201d establishes a myofascial bridge for force transmission, suggesting that \u201cshoulder pain\u201d could be a manifestation of cervicoscapular fascial tension.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s00276-026-03949-0","type":"journal-article","created":{"date-parts":[[2026,7,28]],"date-time":"2026-07-28T13:54:21Z","timestamp":1785246861000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The supraspinatus fascia: a consistently two-layered structure with nociceptive innervation and differential functional anatomy"],"prefix":"10.1007","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-5191-1695","authenticated-orcid":false,"given":"Lara","family":"Herrmann","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6205-4616","authenticated-orcid":false,"given":"Charlotte","family":"Kulow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6510-2943","authenticated-orcid":false,"given":"Pierre","family":"Hepp","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7117-9330","authenticated-orcid":false,"given":"Hanno","family":"Steinke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,28]]},"reference":[{"key":"3949_CR1","doi-asserted-by":"publisher","first-page":"290","DOI":"10.1007\/s12565-024-00775-5","volume":"99","author":"B Arrillaga","year":"2024","unstructured":"Arrillaga B, Miguel-P\u00e9rez M, M\u00f6ller I et al (2024) Human shoulder anatomy: new ultrasound, anatomical, and microscopic perspectives.
