Anatomical Relationships of the Proximal Attachment of the Hamstring Muscles with Neighboring Structures: From Ultrasound, Anatomical and Histological Findings to Clinical Implications. Diagnostics (Basel) 2024; 14:1725. [PMID: 39202213 PMCID: PMC11353185 DOI: 10.3390/diagnostics14161725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2024] [Revised: 07/22/2024] [Accepted: 08/05/2024] [Indexed: 09/03/2024] Open
Abstract
BACKGROUND Injuries of the proximal attachment of the hamstring muscles are common. The present study aimed to investigate the relationship of the proximal attachment of the hamstring muscles with neighboring structures comprehensively. METHODS A total of 97 hemipelvis from 66 cryopreserved specimens were evaluated via ultrasound, anatomical and histological samples. RESULTS The proximal attachment of the hamstring muscles presents a hyperechogenic line surrounding the origin of the semimembranosus and the long head of the biceps femoris muscles, as well as another hyperechogenic line covering the sciatic nerve. The anatomical and histological study confirms the ultrasound results and shows different layers forming the sacrotuberous ligament. Furthermore, it shows that the proximal attachment of the semimembranosus muscle has a more proximal origin than the rest of the hamstring muscles. Moreover, this muscle shares fibers with the long head of the biceps femoris muscle and expands to the adductor magnus muscle. The histological analysis also shows the dense connective tissue of the retinaculum covering the long head of the biceps femoris and semimembranosus muscles, as well as the expansion covering the sciatic nerve. CONCLUSIONS These anatomical relationships could explain injuries at the origin of the hamstring muscles.

Bordoni B, Morabito B. Reflections on the Development of Fascial Tissue: Starting from Embryology. ADVANCES IN MEDICAL EDUCATION AND PRACTICE 2020; 11:37-39. [PMID: 32021541 PMCID: PMC6970272 DOI: 10.2147/amep.s232947] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Accepted: 11/23/2019] [Indexed: 05/05/2023]
Abstract
A great many articles discuss the histological aspects of fascial tissue in detail, but at the same time, there are many contradictions within the literature. In addition, there is a paucity of scientific data that allow straightforward classification of what tissue the fascia truly is. More precise classification of fascial tissue is essential in improving clinical care and effectively framing patient needs. Embryology is an indispensable starting point for understanding the many functions of the fascial tissue. This scientific discipline allows us to observe the relationships and adaptability of fascia both at local and systemic levels. This article reflects on modern scientific knowledge concerning the classification of fascia from an embryological standpoint with the aim of improving our understanding of connective tissue.
