“…None of the piriformis syndrome forms are related to prolapsed intervertebral discs or herniated nucleus pulposus [ 29 ]. They are associated with muscle and joint pathologies, overloading the lower back and buttock [ 36 ], and proceed as a false (pseudo-) sciatica syndrome. The piriformis syndrome with compression of the sciatic nerve occurs quite rarely, just in 6–8% of all sciatica cases [ 24 ].…”

Purpose The cause of the piriformis-related pelvic and extra-pelvic pain syndromes is still not well understood. Usually, the piriformis syndrome is seen as extra-pelvic sciatica caused by the entrapment of the sciatic nerve by the piriformis in its crossing through the greater sciatic foramen. However, the piriformis muscle may compress additional nerve structures in other regions and cause idiotypic pelvic pain, pelvic visceral pain, pudendal neuralgia, and pelvic organ dysfunction. There is still a lack of detailed description of the muscle origin, topography, and its possible relationships with the anterior branches of the sacral spinal nerves and with the sacral plexus. In this research, we aimed to characterize the topographic relationship of the piriformis with its surrounding anatomical structures, especially the anterior branches of the sacral spinal nerves and the sacral plexus in the pelvic cavity, as well as to estimate the possible role of anatomical piriformis variants in pelvic pain and extra-pelvic sciatica. Methods Human cadaveric material was used accordingly to the Swiss Academy of Medical Science Guidelines adapted in 2021 and the Federal Act on Research involving Human Beings (Human Research ACT, HRA, status as 26, May 2021). All body donors gave written consent for using their bodies for teaching and research. 14 males and 26 females were included in this study. The age range varied from 64 to 97 years (mean 84 ± 10.7 years, median 88). Results three variants of the sacral origin of the piriformis were found when referring to the relationship between the muscle and the anterior sacral foramen. Firstly, the medial muscle origin pattern and its complete covering of the anterior sacral foramen by the piriformis muscle is the most frequent anatomical variation (43% in males, 70% in females), probably with the most relevant clinical impact. This pattern may result in the compression of the anterior branches of the sacral spinal nerves when crossing the muscle. Conclusions These new anatomical findings may provide a better understanding of the complex piriformis and pelvic pain syndromes due to compression of the sacral spinal nerves with their somatic or autonomous (parasympathetic) qualities when crossing the piriformis.

“…Low back pain is a very common presenting symptom in the primary care clinic. Between 70 and 80% of the world's adult population has had an episode of low back pain at least once in their life, of these only 10-12% will have concomitant sciatica [1,2]. This pain syndrome is among the first causes of physical limitation in individuals under 45 years of age [1,3,4] although sciatica will rarely be found in patients under 20 years of age, since the predominant age at which it is suffered is around 40 years [5].…”
