چکیده

Introduction. Branches of sacral plexus play an important role in the motor and sensory innervation of the lower limb. Various variations observed during the spinal operations have motivated us to start the study aimed on determination of the sacral plexus formation from its exit of particular roots from sacral foramina up to their formation into terminal branches. Material and method. One hundred sacral plexuses have been examined on 50 adult cadavers for a purpose to find out an incidence of its neural variations. We have considered also the course of their branches, the anatomoses and their thickness. We highlighted the motor innervation particularities in the relation to the diagnosis besides its anatomical complexity and variability. Results. Commonly were observed 3 sacral roots with the share of S4 and lumbosacral trunk of L4 and L5 and 4 sacral nerves. Doubled ascending course of S1 root was often observed, by the other sacral roots the doubled exit was not so frequent. Lumbosacral trunk was thickened in 19 cases. Very high division of the sciatic nerve (in the lesser pelvis) was observed in 2 cases. The branching off level of other nerves depended on the plexus type. Conclusion. Our study revealed a relatively frequent variabilities and described some extraordinary anatomical variations in the formation of nerve roots and branches of the sacral plexus. The detailed knowledge of these variabilities is useful for the proper diagnostics and surgical treatment of the sacral plexus injuries and unexplainable paient‘s complaints.

The posterior sacral foramina: an anatomical study.

The vascular and nervous structures and their relations with the spinal nerve roots were examined in the 2nd, 3rd and 4th posterior sacral foramina in relation to percutaneous needle insertion for neuromodulation. A foraminal branch provided by the lateral sacral artery to each foramen entered the inferior lateral quadrant of each foramen, adjacent to the nerve root medially. Facing the posteri...

The laparoscopic exposure of the sacral roots and the pelvic splanchnic nerves in women during radical pelvic surgery – feasibi

Introduction The nervi splanchnici pelvini were first described as nervi erigentes by Eckhardt in 1863 (1). Since this time, the neuroanatomy of the pelvic plexus using cadaveric microdissection and serial histologic sectioning in human fetuses or using the immunohistochemy technique has been well explored. With the introduction of laparoscopy into the field of pelvic retroperitoneal surgery, l...

The Sacral Parasympathetic Innervation

Autonomic nerves distribute by a variety of methods. They are recognized as components of all spinal and some cranial nerves, but they also have a strong tendency to exhibit a hitch-hiker relationship to arteries and to other nerves. The perivascular plexuses of the head and neck, and of the thorax and abdomen, are especially typical of peripheral sympathetic distribution. In the parasympatheti...
