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 کاملMorphological variations of sciatic nerve and piriformis muscle in gluteal region during fetal period
Intramuscular drug injection in the gluteal region is often the most frequent cause of sciatic nerve injury in preterm newborns. Local anatomic variation is one of the predisposing causes of iatrogenic sciatic nerve injury. The aim of this morphological study was to assess the relationship of sciatic nerve with the piriformis muscle and to elucidate variations of fusion of piriformis with neigh...
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...

15 صفحه اولReport of a Novel Bilateral Variation of Sciatic and Inferior Gluteal Nerve
Sciatic nerve is the thickest nerve of the sacral plexus, which innervates many muscles and vast areas of the skin of the lower limb. It leaves the pelvis via the greater sciatic foramen, emerges into the gluteal region by passing under the piriformis muscle, and descends beneath the gluteus maximus to divide into its terminal branches: tibial and common peroneal nerve at the superior angle of ...
