Neuropathy of the sciatic nerve
Neuropathy - a general name of various kinds of disorders of the nervous system. Today, to the sciatic nerve neuropathy attributed mainly of nerve injury resulting from its pressure or circulatory disorders. These lesions can occur at different levels, as the sciatic nerve is the longest nerve in the human body.
Causes
Neuropathy sciatic nerve appears most often as a result of non-inflammatory lesions of this nerve, developing under the influence of compression (compression) or persistent spasm of blood vessels (ischemic). The affected area of the sciatic nerve often present painful compression or thickening of tissue, which cause narrowing of the bone-ligament-muscular sheaths through which the nerve (the tunnel). Therefore, these processes are called tunneling.
Almost always, when a neuropathy of the sciatic nerve in the process involves the piriformis muscle.
Piriformis muscle is located between the sacral spine and hip joints, it passes through the greater sciatic foramen in the pelvis with the sciatic nerve and blood vessels. Piriformis syndrome is a common tunnel neuropathy. Strong tension piriformis muscle can occur at squeezing the last lumbar root or the first sacral vertebrae or failed intramuscular injections in the gluteal region. Voltage piriformis leads to constriction of the sciatic nerve and blood vessels supplying it.
The sciatic nerve can be affected by various injuries and injuries of the pelvis, inflammatory diseases, malignant and benign tumors of large cysts and pelvic pathology at different gluteal region, the sacroiliac joint and the hip joint.
The defeat of the sciatic nerve at the level of space Subpiriforme
The defeat of the sciatic nerve at the level of Subpiriforme space can manifest as piriformis syndrome. For this syndrome is characterized by aching, nagging pain in the gluteal region, the sacroiliac and hip joints. Pain becomes stronger when walking in an upright position when activated thigh and subsides when lying and sitting with spread legs. Tapping in the piriformis muscle causes pain throughout the back surface of the lower limbs (symptom Vilenkin). When piriformis syndrome can cause problems with urination, often they appear mild urinary retention.
Piriformis syndrome is almost always accompanied by compression of blood vessels and the sciatic nerve. Pain while blunt spilled, give the entire leg. The pain may be aggravated by stress, change of weather or simply by warming the affected area. Compression of the blood vessels causes intermittent claudication (because of the pain the patient is forced to stop when walking), the skin turns pale legs while. After a rest and restore blood flow the patient continues to go, but the attacks are repeated.
Lesions of the sciatic nerve at the level of the thigh and lower
If the sciatic nerve is affected at the level of the thigh and lower, the patient has the following features in gait: straightened the leg while walking brought forward because of the predominance of tone specific muscles. This broken leg flexion in the knee joint, terminated active movement in the foot and toes as a result of paresis.
Deprived of innervation and blood supply of normal muscle fast atrophy (decrease in volume).
It noted an increase in skin sensitivity in the back and the outside of the leg, the rear feet, soles and toes. When lowering the foot pain may dramatically increase. In the defeat against the backdrop of blood disorders and innervation develop trophic disorders (eating disorders tissues): legs and feet become cold and have a bluish tint, nails change color and shape. The patient becomes difficult (or does not do) on the toes and heels.
Diagnosis and treatment
To assign adequate treatment, it is necessary to know the cause of the disease, that is, to find out why, and at what level was the defeat of the sciatic nerve. To do this, conducted various studies: X-ray of the spine, magnetic rezonanstnaya imaging, consulting a gynecologist, urologist, proctologist, the exclusion of inflammatory processes and tumors in the pelvis.
After identifying the main causes of the disease it trying to eliminate or minimize its impact on the sciatic nerve. For pain relief medication use (analgesics, relieves muscle spasm and improves blood circulation drugs) and non-drug (physiotherapy, therapeutic exercises, manual therapy) methods.
Often during the neuropathy of the sciatic nerve becomes long recurrent nature, in such a case is very good spa treatment.
