Osteosarcoma is a type of cancer.
Osteosarcoma is a relatively common type of malignant bone tumor in clinical practice. It mainly occurs near the ends of the humerus, including the area around the head of the humerus, and at the distal end of the femur, near the femoral condyles, as well as the proximal tibia, close to the tibial plateau. These are its common sites. It predominantly affects teenagers, generally those under 18 years of age. The main symptoms include: firstly, persistent and worsening pain that gradually intensifies and does not alleviate, with the notable characteristic being that the pain is more severe at night than during the day; secondly, the appearance of spindle-shaped tumors around the joints, particularly at the three aforementioned common sites, often accompanied by redness, warmth, pain in the superficial skin, and even prominent superficial veins; thirdly, osteosarcoma is a type of malignant tumor, classified as grade 2B among malignant tumors. Its main feature, apart from local symptoms, is its propensity for metastasis, with the lungs being the most likely site of metastasis.

Is massage useful for lumbar disc herniation?
Can massage be used for lumbar disc herniation? Its clinical effects are quite good. The primary function of massage therapy is to relieve muscle spasms, then dilate blood vessels, increase local blood circulation, and promote peripheral metabolism, thereby achieving the purpose of curing diseases. It mainly uses rolling and pushing techniques, with the main acupoint being the Jiaji acupoint. Auxiliary acupoints generally include Yangguan, Yaoyangguan, Mingmen, Shenshu, Weizhong, Chengshan, and Yanglingquan, among others. Additionally, it includes two board techniques. These board techniques are very effective for minor joint disorders of the lumbar spine. There are two board techniques, one is the slant board technique, and the other is the rotating tube board technique, with the slant board technique being relatively easier to perform. Generally, patients experience varying degrees of symptom relief after proper and effective massage, and many people's symptoms disappear altogether.

What are the symptoms of a rib fracture?
Symptoms of rib fractures include, firstly, there is usually a clear history of trauma, either from direct impact or from falling and the ribs making contact with the ground, etc. Secondly, the main symptoms of a rib fracture include three points: The first is local deformity. If it is a single rib fracture, this deformity is generally not easy to detect. However, after multiple rib fractures, this deformity becomes readily apparent, and you can see that the chest cage is abnormal, with a caved-in appearance. Moreover, in cases like flail chest, breathing is also abnormal. Normally, when inhaling, the ribs should expand outward, but if flail chest occurs, the chest cage appears to expand inward during inhalation; therefore, such a condition often requires surgical treatment, otherwise the consequences are very serious. The second symptom is friction sound and bone rubbing sensation. Some people, after fracturing a rib, during deep breathing or activity, hear cracking sounds from within. This occurs because the continuity and integrity are disrupted by the fracture, and then during breathing or during movement, there is friction between the bones. The third point is abnormal movement, which occurs at locations without joints, resembling joint movements. Normally, a person has 12 ribs on each side. If the continuity and integrity of the ribs are not damaged, there should be no abnormal movement; that is, pressing on the ribs should not cause sensations similar to joint movements at places where there are no joints. Therefore, the symptoms of a rib fracture include three points: the first point being local deformity; the second, bone friction sounds and sensations; and the third, abnormal movement. If any of these three symptoms are present, it is generally indicative of a rib fracture.

What are the methods for diagnosing lumbar disc herniation?
The diagnostic methods for lumbar disc herniation are essentially three-dimensional; that is, clinical symptoms plus physical examination combined with auxiliary examinations. First, let's talk about clinical manifestations, which include pain, functional impairment, and local sensory abnormalities in cases of lumbar disc herniation. Second, in the physical examination of lumbar disc herniation, the intervertebral disc often shows some deformation, and the most common is a reduction or disappearance of the lumbar spine's forward physiological curvature, referred to colloquially as "flatback," where the back appears flat like a board. Other findings may include spinal scoliosis and specific tender points, usually located next to the protruding vertebrae. Percussing these tender points may induce radiating pain to the buttocks or lower limbs. Additional examinations might reveal abnormalities in the strength or sensation of lower limb muscles at different stages, as various muscles and sensory areas are affected differently. Special tests such as the straight leg raise test, femoral nerve stretch test, and neck flexion test are generally positive. The most routine auxiliary examination involves taking x-ray images, followed by CT scans, which can directly visualize the location and extent of the disc herniation. Currently, magnetic resonance imaging (MRI) is also used, which has significant advantages. MRI provides three-dimensional images, showing the sagittal, coronal, and axial planes, which helps in better assessing the condition of herniated discs. Therefore, these are the areas covered in diagnosing lumbar disc herniation.

What are the symptoms of osteoporosis in women?
Symptoms of osteoporosis in women generally include the following: The first is pain, which can be localized back pain or generalized pain throughout the body. The second is spinal deformity, which is often manifested by bending and hunching over, as well as some individuals appearing shorter than before—these conditions are also caused by osteoporosis, leading to reduced bone strength and vertebral deformity. The third is brittle fractures, which occur because osteoporosis leads to a reduction in bone mass, making the bones less sturdy. Even a minor external force can cause a fracture, for example, a simple fall might result in a distal radius fracture. Thus, the basic symptoms of osteoporosis in women include pain, spinal deformity, and brittle fractures.

What is sciatica?
Sciatica refers to severe pain caused by various reasons that result in the compression and irritation of the sciatic nerve. The typical pain of sciatica radiates from the lower back to the buttock or the back of the thigh and the lateral side of the leg down to the foot. The pain can intensify during coughing or increased abdominal pressure. Additionally, this condition is often accompanied by dullness or numbness, and in a minority of cases, it can cause bilateral sciatica. Generally, there are three main causes of sciatica: The first is chemical irritation, mainly when the disc tissue comes into contact with the sciatic nerve, releasing chemical substances that stimulate and trigger an autoimmune response, resulting in neuritis. The second cause is mechanical compression, primarily from protuberance and nucleus pulposus compression or traction on the already inflamed nerve root, leading to obstructed blood flow and worsening edema. The third cause follows chemical stimulation and mechanical compression, leading to ischemic symptoms in the injured nerve, which then results in pain. Therefore, sciatica typically has primary and secondary causes. The primary cause is sciatic neuritis, while secondary causes are usually associated with lumbar spinal stenosis, lumbar disc herniation, lumbar tumors, and piriformis outlet syndrome.

Can sciatica be cured completely?
Sciatica is difficult to cure completely. If it is primary sciatica, which is caused by inflammation of the sciatic nerve, there is a possibility of complete cure after medical treatment. However, secondary sciatica is generally difficult to completely cure because it is usually caused by spinal diseases, such as herniated discs, spinal stenosis, or even spondylolisthesis. In such cases, even after solving the primary disease, some problems may persist, continuing to stimulate the sciatic nerve, making it difficult to cure completely. If the sciatica is caused by spinal tuberculosis or a spinal tumor, the situation is even more complicated. Even if the primary lesion is resolved, it cannot guarantee that it will not recur. Therefore, sciatica is difficult to cure completely.

Postoperative recurrence symptoms of osteosarcoma
Symptoms of recurrent osteosarcoma after surgery are generally consistent with the symptoms before the initial surgery. The main symptoms include: Firstly, localized pain, which is persistent, progressive, and does not alleviate, including pain that worsens at night. Secondly, localized swelling, which usually occurs around the surgical site if limb-sparing surgery was performed, or at the stump if amputation was done. Thirdly, the appearance of systemic cachexia and symptoms of metastasis. Systemic cachexia typically includes weight loss, anemia, fatigue, and loss of appetite. For osteosarcoma, metastasis primarily targets the lungs, where numerous cancerous shadows can be detected. Thus, the main recurrent symptoms of osteosarcoma after surgery include pain, swelling, and cachexia.

Is there a cure for lumbar disc herniation?
Lumbar disc herniation is treatable, and the results after treatment are very good. The treatment methods for lumbar disc herniation mainly depend on the direction and degree of the herniation as well as the symptoms it causes. Generally, it is divided into conservative treatment and surgical treatment. Conservative treatment is the first approach, which initially includes general treatment. That is to say, after experiencing symptoms of a lumbar disc herniation, you must first rest in bed and then make sure to sleep on a flat bed and appropriately strengthen the muscles of the lower back. The second approach is traditional Chinese medicine, the third is traction and massage therapy, the fourth is physical therapy, and the fifth is rehabilitation therapy. If the treatment is not effective, or other surgical indications appear, such as urinary and fecal incontinence or spinal cord type nerve damage combined with spinal stenosis, then surgical treatment is needed. Surgical treatments generally include conventional surgery and minimally invasive surgery, with the latter being more commonly used nowadays. Other treatments include disc sealing, sacral therapy, small needle knife therapy, and nucleus pulposus injection with ozone, among others. Overall, not only is lumbar disc herniation treatable, but there are also many treatment methods. However, as to which treatment method is suitable for you, you must go to the hospital and consult a doctor to decide.

Osteosarcoma mainly metastasizes through
The main metastatic pathways of osteosarcoma are generally divided into three types. The first is hematogenous spread, which refers to the dispersal of tumor cells throughout the body via the bloodstream, typically settling in areas with slower blood flow which facilitates the deposition of these cells leading to local changes. The second is direct implantation, which involves tumor cells directly establishing themselves in the vicinity of the tumor's common sites, eventually leading to local metastasis. The third type is lymphatic spread, where tumor cells migrate through the lymphatic system, spreading along lymphatic vessels or pathways. Therefore, the main metastatic pathways of osteosarcoma are these three types. The primary sites of metastasis for osteosarcoma are mainly the lungs, but metastases can also occur in the brain or through other mechanisms.
