Abstract
The greater sciatic foramen is a region of practical interest to a wide range of specialists due to the numerous nerve trunks that pass through it, which may be subjected to compression in this area or be damaged during invasive medical procedures. The aim of the study is to analyze the sources of literature on the anatomy of the greater sciatic foramen and its related components to identify underexplored issues. Materials and Methods. The research materials include information databases, scientific articles, reviews, and monographs available in the public domain and held in the collections of scientific medical libraries. The literature analysis showed that the most studied structure of the greater sciatic foramen is the piriformis muscle. Various classifications of this muscle have been proposed, taking into account the sites of its attachment to the sacrum, the length of its bellies, and the position of the sciatic nerve relative to this muscle. The data presented demonstrate that the question of the influence of the morphology of this muscle on the development of piriformis syndrome remains a topic of discussion and is unresolved. At the same time, the bony structures forming the edges of the sciatic foramen are insufficiently studied. The greater sciatic notch of the pelvic bone shows pronounced sexual dimorphism in size and shape; however, its influence on the parameters of the foramen as a whole is not well-covered in the literature. Conclusion. There is a need to determine the sizes and shapes of the greater sciatic foramen in relation to the sizes of the piriformis muscle, taking into account individual characteristics of the body.
