What are the causes of piriformis injury?

Piriformis injury syndrome is commonly known as piriformis injury syndrome. It is thought that the common peroneal nerve is a high branch that exits from the piriformis fascicle or the sciatic nerve exits from the piriformis abdomen.

A When the piriformis muscle is damaged, congestion, edema, spasm, adhesion and contracture occur, the muscle space or the lower foramen on the muscle becomes narrow, squeezing the nerves and blood vessels that penetrate between them, and a series of clinical symptoms and symptoms are called piriformis injury syndrome.

Piriformis syndrome is caused by damage to the sciatic nerve that passes through the piriformis muscle, and can be caused by a number of causes. First of all, the buttocks are injured, which causes bleeding in the local tissues, and then adhesions and scar tissue formation, which can lead to the pinching of the sciatic nerve, so the piriformis syndrome is formed.

Repeated local injections may lead to the formation of local scar tissue, abnormal contraction and spasm of the piriformis muscle, in which case piriformis syndrome may also form.

A severe fracture of the posterior upper part of the acetabular has led to the displacement of the fracture, and a large number of callus has formed during the healing process of the fracture, which may also lead to the compression of the sciatic nerve in the piriformis muscle, resulting in piriformis syndrome. Others are caused by abnormal development of the sciatic nerve, and in some patients, prolonged sitting and standing may also cause piriformis syndrome.

Piriformis syndrome is related to trauma, especially the trauma of the buttocks, which can easily lead to edema, bleeding of the piriformis muscle, and later adhesions and contractures, resulting in compression of the sciatic nerve.

Then there is the local injection of drugs in the buttocks, which can easily lead to an increase in the fragility of piriformis degeneration, which can cause fibrous contractures and cause sciatic nerve compression.

cPiriformis strain, this condition and the patient's repeated bending over activities and not paying attention to the sitting posture after sitting for a long time can easily lead to long-term stretching of the piriformis muscle, causing the piriformis muscle to appear strain edema, thereby compressing the sciatic nerve and causing piriformis syndrome.

1. Lumbar intervertebral disc herniation is secondary to lumbar disc herniation, resulting in radicular compression of sciatica, sciatic dystrophy or pain spasm, involving piriformis muscle injury, and producing symptoms. 2.Pelvic inflammatory disease, peritonitis, hip or sacroiliitis, etc., spread to the piriformis muscle, causing inflammatory changes in the piriformis muscle.

1.Sudden high-intensity exercise after a long period of inactivity; 2.Sudden pulling of overweight cargo; 3.Suddenly get up after sitting for a long time; 4.Insufficient stretching before exercise; 5.Leaning over for a long time.

1. After a long period of inactivity, suddenly high-intensity exercise, 2. Suddenly pulling overweight goods, 3. Suddenly getting up after a long time of sitting, 4. Stretching before exercise is not in place, 5. Bending over for a long time.

Pain in the buttocks and reflexes to the posterior or lateral aspect of the ipsilateral lower extremity. Patients with acute injuries are more painful, may present with pulling, burning, or stabbing pain, are unable to walk, and feel that the affected limb is shortened or has a limp, but the hip joint is functionally normal. Patients with chronic injuries often experience soreness and numbness in the buttocks or lower limbs on the affected side, which is aggravated by activity or exertion and can be relieved after rest.

Piriformis syndrome is characterized by sciatica. When the symptoms are mild, the main symptoms are hip pain and radiating pain in the lower limbs, and in severe cases, the pain is severe and you cannot walk or need to rest for a while before you can continue walking.

Typical symptoms. It usually presents with pain in the buttocks on the affected side, which radiates along the sciatic nerve (from the buttocks through the back of the thighs to the calves and feet).

When the pain is severe, the patient may have painful claudication and even difficulty walking.

Sitting cross-legged, bending, and lifting heavy weights can cause pain to worsen, which can be relieved to varying degrees by traction.

A fusiform, sausage-shaped mass (scar or callus) may be palpable at the anatomical site of the piriformis muscle.

Some patients will have atrophy of the gluteal muscles, calf muscles, and paresthesias below the calf**.

TCM massage is effective.

Please refer to it.

For piriformis muscle strain, within 24 hours of the strain, local ice should be applied to constrict the local ruptured blood vessels, reduce bleeding and swelling, and after 24 hours, local hot compress can be applied to improve local blood circulation and speed up the healing of tissues.

The use of anti-inflammatory, analgesic drugs, including celecoxib, meloxicam, Ankangxin, Lesong, diclofenac sodium, can play a good anti-inflammatory, analgesic effect, topical application of voltarin ointment, try to avoid sitting for a long time, because the piriformis muscle will be compressed when sitting for a long time, which is not conducive to healing. Generally, it takes 2-3 weeks to heal with adequate rest, otherwise the piriformis muscle may become scarred and form piriformis syndrome.

Precautions for piriformis injury.

For patients after piriformis injury, the main manifestations are painful symptoms, and severe may affect normal activities, and the question of how long can patients get better after piriformis injury is mainly based on the degree of injury and the degree of active attention to rest and protection in the later stage.

If the injury is not serious, and the later active attention to rest protection, generally about a week can be recovered, if the time is relatively long or has formed a chronic injury or the injury is more serious, and there is no active attention to rest protection, active cooperation**, the recovery time of this situation is difficult to say, the general time should be relatively long.

bleeding, adhesions, scarring of buttocks trauma; Injectable drugs cause piriformis muscle degeneration and fibrous contractures; Posterior upper acetabular fracture displacement and excessive callus can compress the sciatic nerve at the piriformis muscle. In addition, a small number of patients have a small number of patients who travel through the piriformis muscle due to the variation of the sciatic nerve when it exits the pelvis, but the strong contraction of the hip external rotation muscle can put excessive pressure on the sciatic nerve, resulting in chronic sciatic nerve injury in the long run.

The piriformis muscle is located in the center of the entire buttocks of the human body. Piriformis muscle injury is clinically characterized by pain and tenderness, and the pain is significantly worse when squatting and bending over. It can be treated with a warm compress, which can significantly reduce symptoms.

Generally, piriformis injury is pain in the buttocks, which causes pain in the ipsilateral leg not behind and on the outside. When the attack is acute, there is a burning or knife-like pain, and it is impossible to walk. If it is chronic, the patient will feel soreness and numbness, and the symptoms will be relieved after resting.

If there is no abnormality on the x-ray during the examination of this symptom, the doctor needs to rule out lumbar disc herniation and hip arthropathy, and if there is a tender point, the diagnosis of piriformis muscle injury can be confirmed.
