This is some time ago.
A young lady who came to see a doctor.
Complaining of symptoms.
Internet.
As everyone knows. It's all made up of.
caused by piriformis syndrome.
So. What is piriformis syndrome?
*What is it?What are the symptoms?
Health Jun will take you to understand.
What is piriformis syndrome?
To know what piriformis syndrome is.
You have to know where the piriformis muscle is first.
Internet.
Location: In front of the sacrum, through the greater ischial foramen, the greater ischial foramen is divided into upper and lower parts
Starting point: edge of the second to fourth anterior sacral foramen of the sacrum.
Insertion: the tip of the greater trochanter.
Function: Hip external rotation, abduction, strengthens hip stability.
Innervation: Innervated by S1 S2 nerves.
Neurovascular travel: the superior piriformis foramen has the superior gluteal nerve and superior gluteal artery and vein;The inferior piriformis foramen has the inferior gluteal nerve, sciatic nerve, posterior femoral cutaneous nerve, inferior gluteal artery and vein, and **internal artery.
Internet.
Definition: The piriformis muscle is a flat, band-like muscle located in the uppermost layer of the external rotator muscle of the hip joint. The sciatic nerve is the largest nerve in the body and controls sensation and movement in the lower limbs.
About 85% of the sciatic nerve passes out of the pelvis from below the piriformis muscle, and a few people with structural variations pass the sciatic nerve directly from the piriformis muscle.
When the piriformis muscle is damaged for various reasons, local inflammation, hyperemia, edema, and spasms can occur, which in turn compresses and stimulates the sciatic nerve, forming piriformis syndrome.

How is piriformis syndrome diagnosed?
How?Are there any tests that can be diagnosed easily, quickly, and at a fraction of the cost?
How is piriformis syndrome diagnosed?
*: Trauma, fractures, congenital developmental variations, long-term strain, fixed posture compression, hip hypermobility, intramuscular injection of the buttocks in children, etc.
Clinical manifestations: The main symptoms are hip pain and radiating pain in the lower limbs, and patients are even unable to walk normally when the symptoms are severe. Chronic patients may have gluteal muscle atrophy and shortening of the affected limb.
Internet.
Diagnosis:1On the affected side, there are symptoms of soreness, pain, and numbness in the buttocks and legs.
2.Where the piriformis muscle projection (near the ring jump) is palpable, cords (fibrous scars) or lumps (callus).
3.The straight-leg raise test may be positive, but the pain is less painful than 60°.
Internet.
4.External antagonism in the "4" test can aggravate or induce sciatica, and the tinei sign is positive in the buttocks tenderness.
5.CT or MRI can show the size of the piriformis muscle, sciatic nerve compression, and rule out tuberculosis, tumors, lumbar disc herniation, and lumbar spinal stenosis.
6.Ultrasonography, similar to MRI, can also reflect the size of the piriformis muscle and sciatic nerve compression, and has the advantages of being quick, easy, and inexpensive.

Piriformis syndrome way
It mainly relieves pain and improves or restores the ability to perform daily activities. There are surgical and non-surgical classifications.
The vast majority of patients can be surgical**, and surgery is only used when non-surgical** is ineffective and the diagnosis is clear.
1.Medications**: including non-steroidal anti-inflammatory drugs, muscle relaxants, local anesthetics, and neurological drugs.
2.Technique**: After determining the projection site of the piriformis muscle surface, hand push or hand pull, elbow pressure, etc.
Internet.
3.Injection**: Directly by injection or guided by ultrasound, MRI, or CT.
4.Surgery**: Typically includes piriformis tenotomy and sciatic nerve decompression. It is important to remember to rule out other possible diagnoses before surgery.
5.Others**: Physics** (infrared heat therapy, electrotherapy, etc.), Traditional Chinese Medicine** (Chinese medicine fumigation, acupuncture, etc.), etc.
It's better to prevent it early
1.Maintain a good posture in daily work and life. Avoid actions that are easy to induce piriformis syndrome, such as sitting for a long time, stilted legs, some activities that twist the torso, etc., which are easy to cause piriformis muscle strain, and should pay attention to the combination of work and rest, and avoid working in a fixed position for a long time.

2.Warm up properly before exercising and gradually increase the intensity of exercise;
Avoid running or exercising on uneven ground or hills, and avoid sprains or strains in the event of a fall
If you feel pain in your hips and lower limbs, you should stop exercising and rest in time, find the cause of the pain, seek medical attention in time if necessary, and do not blindly insist on training.
