Variations in the high division of the sciatic nerve and relationship between the sciatic nerve and the piriformis.
OBJECTIVE The sciatic nerve (SN) separates into its branches, the tibial and common fibular nerves, outside the pelvis. However, it may rarely be separated within the pelvis. In such cases, the tibial nerve and the common fibular nerve may leave the pelvis through different routes. These variations may cause nerve compressions under other anatomic structures, resulting in non-discogenic sciatic...
متن کاملA Rare Anatomical Variation of Sciatic Nerve and its Relationship with Piriformis Muscle
Sciatic nerve is the thickest nerve of the body which is formed by ventral branches of L4, L5, S1, S2 and S3 of spinal nerves as a part of sacral plexus in pelvis. It leaves the pelvis via the greater sciatic foramen below piriformis muscle and descends between the greater trochanter and ischial tuberosity, along the back of the thigh and dividing into the tibial and common peroneal (fibular) n...
متن کاملAnthropometric Study of the Piriformis Muscle and Sciatic Nerve: A Morphological Analysis in a Polish Population
BACKGROUND The aim of this study was to determine relationships between piriformis muscle (PM) and sciatic nerve (SN) with reference to sex and anatomical variations. MATERIAL AND METHODS Deep dissection of the gluteal region was performed on 30 randomized, formalin-fixed human lower limbs of adults of both sexes of the Polish population. Anthropometric measurements were taken and then statisti...
متن کاملThe endoscopic treatment of sciatic nerve entrapment/deep gluteal syndrome.
PURPOSE The purpose of this study was to investigate the historical, clinical, and radiographic presentation of deep gluteal syndrome (DGS) patients, describe the endoscopic anatomy associated with DGS, and assess the effectiveness of endoscopic surgical decompression for DGS. METHODS Sciatic nerve entrapment was diagnosed in 35 patients (28 women and 7 men). Portals for inspection of the pos...
متن کاملUnique formation of sciatic nerve below the piriformis muscle - a case report.
Dorsal and ventral divisions of ventral rami of lower lumbar and sacral spinal nerve were found to pass ventral and dorsal to the piriformis muscle respectively. These divisions joined each other below the piriformis muscle to form sciatic nerve. This low formation of sciatic nerve was observed in distal part of left gluteal region of a 50-year-old male cadaver. The sciatic nerve thus formed pa...
