Sciatica is one of the most common lower back injuries seen in chiropractic offices. Sciatica is a lower back, buttocks and pain in the legs, which may be accompanied by numbness, tingling or burning pain. It is usually one-sided, but it can simultaneously include both legs. True sciatica can have many causes, but the most common result is muscle and skeletal problems in the lower back and buttocks. Chiropractic care provides quick, natural pain relief without the use of harmful drugs and surgery. Thick muscles and spasms can lead to abnormal displacement of the spine and pressure on the sciatic nerve. The most common treatment for sciatica is to start at home with ice and rest. Ice should be applied on the lower back on the side of the leg with an interval of 15-20 minutes with an interval of about 30 minutes between applications. If the pain does not disappear within 3-4 days, it is recommended to consult a doctor. In some cases, additional studies may be required, including radiography, MRI, or testing of the speed of nerve tightening. Once it is determined that there is no serious injury or an organic cause for injury, chiropractic is a natural, cost-effective form of treatment that can provide lasting relief for back and leg pain. Chiropractic usually begins with ice therapy and may include electrical stimulation of the muscles to reduce swelling and muscle tension. Specific stretching is then used to weaken the back muscles and remove pressure from the sciatic nerve. Using mild chiropractic adjustments, the chiropractor then rearranges the spinal cord to remove further tension from the nerve and provide healing and recovery. The patient is then provided with specific stretch marks and exercises to be performed at home with icing in order to maintain his back and strengthen any weak parts. To fully understand sciatica, I will now discuss in detail the structures involved and the medical explanation of the mechanism of injury.
In most cases, the sciatic nerve is affected by a number of structures in the lower back and pelvic region. The serial nerve is the largest nerve in the body, which is measured at 2 cm at the beginning and is formed from the sacral plexus by the ventral rami L4-S3. It leaves the pelvis through the greater sciatic opening, moves under the front of the piriformis, passes behind the sacrospinal ligament, and then descends along the posterior aspect of the hip after the femur to provide the skin of the posterior and lateral part of the leg and leg, as well as the motor to the muscles of the posterior thigh legs and feet. The serial nerve consists of two main sections: the tibial nerve and the common peroneal nerve nerve. The tibial nerve descends through the popliteal fossa and divides into the flexor retinaculum into the medial and lateral plantar nerves. Its main function is to supply motor innervation to the posterior muscles of the knee joint and legs. The common peroneal nerve descends from the medial aspect of the femoral biceps and extends along the posterior aspect of the peroneal head, where it is divided into superficial (lateral separation of the legs) and deep (anterior finishes) fibular nerves. The connection between the sciatic nerve and the pyriform muscle is very important, especially in this case. Usually, the sciatic nerve passes below the pyriformis muscle because it leaves the lower part of the larger sciatic orifice, but it is estimated that 12.2% of the population divides before it enters the gluteal region, and the common fibular division passes directly through the pyriform muscle, He divides early 0.5% of the population, and the general fibular division crosses pyriform best of all. The piriformis mouse itself helps stabilize the head of the femur in the acetabulum and outwardly rotates the enlarged hip and steals the bent hip. It moves from the anterior surface of the sacrum and the sacral-connected ligament to the upper part of the greater trochanter of the femur. It is innervated by the ventral ramies S1 and S2 and does not receive innervation from the sciatic nerve.
Sciatica is defined as acute pain in the leg along the sciatic nerve caused by irritation, contraction or trauma to the sciatic nerve or its roots. Many factors can lead to irritation of the sciatic nerve, leading to pain in the back and leg. The mechanical aspects of nerve compression play a large role in cases of sciatica. The serial nerve can be slowly compressed and deformed from factors such as multiple disc bulges, disc herniation, degenerative changes such as discounted spondylosis, facet arthrosis, stenosis and osteophytosis, and then peripherally in the piriformis muscle. When compression occurs either in the center or around the periphery, it impairs the function of the nervous system due to the compromise of vascular nutrition. When it comes to any compression of the nerve in the body, the first structures to be compressed are inside the venous system, causing blood to stagnate. Venous congestion leads to a capillary table, which then changes the microcirculation on the nervous tissue. This reduction in nerve tissue perfusion causes hypoxia or a decrease in oxygen content. Without an adequate level of oxygen, cells can no longer produce an energy-rich ATP molecule through oxidative phosphorylation. Without ATP, important Na + / K + pumps inside the neural membrane can no longer maintain the required ion gradient across the membrane. This leads to a leakage of Na + into the cell and a change in the potential of the resting membrane (RMP) of the nerve. Usually this RMP is -70 mV. With normal depolarization, the nerve firing threshold is around -55 mV. As soon as the ionic charge in the nerve reaches this threshold, the nerve will burn. Leakage of Na + into the cell causes RMP near the threshold. This leads to a hypersensitive nerve, which requires very little to contribute to the fire. This is the cause of associated numbness and paresthesia in the sciatic nerve area. Pain is also perceived much easier in this condition. If the pressure on the nerve is not relieved, chronic hypoperfusion and hypoxia will lead to neural death. In cases involving arthritis, the patient may develop osteoarthritic changes through the lumbar spine. In the early stages of degenerative joint disease, intervertebral disc dehydration causes thinning and approximation of bone structures. Damage often begins inside the inner part of the disc, which is not innervation, and then goes unnoticed. Over time, the compressive forces deform the inner core, the shear and rotational forces cause tears and weakening of the annular fibers. The disc ring is strongly innervated by the sinuvertebral nerve and can cause large diffuse back pain. This weakening can lead to disc bulging and hernia in the extradural space and can cause harmful and chemical forces in the nervous structures, including the cord and nerve roots of the sciatic nerve. This manifests itself as a sharp pain along the neural pathway and causes antalgia. If the internal materials of the disc completely protrude in the later stages of the disease, it may cause an increase in pain and tenderness. This is due to the attractive properties of glycosamine-glycans for water when they leave the confined space of a disk. This hydrophilic tumor will put more pressure on nerve structures. As the degeneration of the disc continues and the bone structures of the spinal column contact each other, reflex hypertrophy occurs to protect the surfaces. This is manifested in subchondral sclerosis of the vertebral bodies, often leading to the fact that the space is occupied by osteophytes protruding into the nerve canal. Arophysial arthritis occurs in the posterior aspect of the nerve canals, and in the case of Irina, hypertrophy of the ligament flavum occurs. Together, all these degenerative changes cause stenosis in the canal and create extradural contraction forces on the nerve roots of the sciatic nerve. Stenosis can lead to single or bilateral sciatica. If centralized, lower back pain is more common.
Since the sciatic nerve leaves the greater sciatic eye, it can also be compressed because it crosses the pyriform muscle in the gluteal region. Cases of sciatica, such as these, are called syphilis syndrome piriformis, which is very common. A spasm or hypertonus of pyrofat compresses the sciatic nerve. These syndromes of the capture of peripheral nerves usually occur when the nerve passes through the teeth or through muscles or fibrous tissues. These symptoms of nerve compression usually develop gradually, and pain and paresthesia are the most common complaints. Weakness can be seen later in chronic situations, although in the case of older people it can be difficult to detect. These are just some of the most common causes of sciatica, but any serious case should be evaluated by a health professional if the symptoms remain unchanged or worsen after initial ice and rest.
