Where to apply moxibustion for lumbar disc herniation
If moxibustion is used to treat a lumbar disc herniation, the main acupoint is the Jiaji acupoint located on both sides of the herniated disc, along with the Jiaji acupoints immediately above and below it. For example, if you have a herniation between the 3rd and 4th lumbar discs, you should moxibust the 2nd, 3rd, and 4th Jiaji acupoints, and so on. In addition to the main acupoint, there are auxiliary acupoints chosen based on the different symptoms of different patients. Generally, if there is significant back pain, the acupoint on the affected side is the Yaoyan. If there is muscle tension and tenderness in the buttocks, match with Huanjiao and Yibian. If there is muscle tension on the back of the thigh, match with Chengfu, Yinmen, and Weizhong. If there is numbness on the outer side of the thigh, match with Fengshi, and for calf numbness, match with Weiyang, Chengshan, and Yanglingquan. If there is numbness on the top of the foot, followed by weakness in the foot or toe region, match with Taixi, Jiexi, and Xiexi.
Is a comminuted patellar fracture serious?
Patellar comminuted fractures are usually quite severe because once the patella is shattered, it can no longer guarantee a smooth cartilage surface. Moreover, the more severe the fragmentation, the harder it is to restore smoothness. If the smooth surface is not well restored, certain conditions can arise. The first is post-traumatic arthritis, the second is patellar chondromalacia, and the third is patellofemoral arthritis. Therefore, patellar comminuted fractures usually require open reduction and internal fixation surgery. In this surgery, it is crucial to align the cartilage surface of the patella as accurately as possible, making the joint surface as smooth as possible, and then fasten it securely with wire loops or tension bands. If the patellar fragmentation is particularly severe, and it's impossible to restore the integrity of the cartilage surface, it may be considered to remove the patella. If feasible, a prosthetic patella can be installed. If not, the ligaments and joint should be repaired, and then functional exercises should begin three to four weeks post-surgery, although this method of surgery typically results in weakness in extending the knee on the affected side.
How to treat tendonitis and strains?
How to treat tendinitis and strain? That is, in cases with tendinitis that have also resulted in acute injury, the approach should align with treating acute injuries associated with tendinitis. Firstly, rest and immobilization. Resting helps to prevent further injury, and immobilization allows joints or tendons time to relax, rest, and repair. Secondly, apply ice. Ice should be applied to the injured area immediately after the injury. Typically, the first icing lasts for half an hour, followed by subsequent half-hour sessions every three hours, continuing up to 48 hours, after which it should switch to heat application. Thirdly, immobilize the joint or tendon. Immobilization serves two purposes: first, to prevent the injury from worsening; second, to help prevent further swelling. Fourthly, the injured limb should be elevated, raised above the level of the heart by 30 degrees. This is the internationally renowned RICE principle for treating tendon strains and injuries, focusing primarily on four aspects: rest, ice, compression, and elevation.
Symptoms of lumbar muscle strain and fasciitis
First, it is a type of chronic pain without obvious causes, mainly characterized by soreness and swelling. The pain usually alleviates after rest but reappears if staying in one position for too long. Therefore, patients with myofascial inflammation caused by lumbar strain often feel restless. Second, there is usually a trigger point, typically located near or within a muscle, or at the junction between muscle and nerve. Pressing on the trigger point often results in radiating pain around it. Furthermore, the pain usually does not worsen but instead lessens over time, which is a key characteristic of myofascial inflammation. Third, the sacrospinalis muscle may become hardened or even spasm on one or both sides. Fourth, there is compensatory abnormal curvature of the spine, mainly presenting as protrusion or lateral curvature of the spine. Thus, the symptoms of myofascial inflammation from lumbar muscle strain usually include pain, specific pain points, surrounding muscle hardening, spasm, and compensatory spinal deformity.
Can tendinitis be seen on an X-ray?
If you are referring to taking an X-ray, tendonitis can only be detected in one situation by X-ray, that is, if the tendonitis has caused calcification. Only then the calcification appears as a high density on the X-ray; otherwise, X-rays won’t show tendonitis. The best examination for tendonitis is magnetic resonance imaging (MRI) because MRI excels in viewing soft tissue disorders, a capability unmatched by other examinations. So, if you suspect you have tendonitis, an MRI should be the first choice, and taking X-rays is not very significant.
What is Ankylosing Spondylitis?
Ankylosing Spondylitis (AS), where "A" stands for fusion and "S" for spine, refers to the condition where the bones and joints of the spine are fused together. Ankylosing Spondylitis is defined as a chronic inflammatory disease primarily affecting the axial skeleton and major limb joints. It is characterized by fibrosis and ossification of the intervertebral discs’ annulus fibrosus and nearby connective tissues, as well as ankylosis (stiffening) of the joints. It presents as a sterile inflammation occurring in the spine. However, it is not solely limited to the spine as it also involves the axial bones and major limb joints. The pathological hallmark of the disease includes inflammation mainly at the sacroiliac joints and points of attachment to the spine, leading to joint stiffness and calcification of the spinal ligaments and joints. The disease progression begins at the sacroiliac joint, spreading upwards through the entirety of the spine, and eventually stops at the cervical vertebrae. Symptoms start with pain in the early stages, followed by restricted mobility in the intermediate phase, and ultimately leading to deformities of the abdomen and back, culminating in severe hunchback. The exact cause of Ankylosing Spondylitis remains unclear, with various theories proposed but none universally accepted. Additionally, it is categorized under rheumatologic and immunologic disorders.
Tendonitis
Tendonitis refers to a sterile inflammation of the tendon itself or its surrounding sheath caused by various reasons. The term "tendonitis" means that, firstly, the affected area is either the tendon or the surrounding tissue. Secondly, it is a sterile inflammation. The causes of tendonitis are generally the following four points: The first point is acute injury. The second point is chronic overuse. The third point is an increased load on the tendon itself, causing some micro-damage inside the tendon. This leads to inflammation due to bleeding and inflammatory irritation in the tendon or around the tendon. The fourth point involves prolonged exercise or excessive exercise load, which then leads to congestive hematoma around the tendon, ultimately leading to inflammation.
Is osteosarcoma treatable?
Osteosarcoma is not about whether it can be treated, but it must be treated. Moreover, the earlier the treatment, the higher the five-year survival rate. Currently, the treatment for osteosarcoma still primarily involves comprehensive therapy centered around surgery. With the advent of neoadjuvant chemotherapy, the five-year survival rate for osteosarcoma has significantly increased. Specifically, once osteosarcoma is diagnosed, extensive chemotherapy is administered before surgery. After chemotherapy, depending on the extent of tumor invasion, either radical segmental resection, limb-sparing surgery, or amputation is considered. Postoperative treatment also requires continued high-dose chemotherapy. In fact, if osteosarcoma is not treated, it metastasizes very quickly, primarily to the lungs. However, if the treatment is very early, timely, and correct, the current five-year survival rate has reached about 80%. Therefore, osteosarcoma can be treated, and the earlier the treatment, the better the outcomes.
What is osteosarcoma?
Firstly, osteosarcoma is a common type of malignant tumor, characterized by a mechanism that produces bone-like tissue. It has multiple subtypes and can also develop into a secondary osteosarcoma. Secondly, it commonly occurs in adolescents. Thirdly, it typically affects the proximal femur, distal tibia, and proximal humerus. Fourthly, common osteosarcomas are generally spindle-shaped, often located near joints. The surface may have elevated skin temperature and sometimes superficial vein distension is apparent. It often involves the entire bone, including the periosteum, cortical bone, and bone cavity. Generally, the tumor appears as a very fine greyish-white or brownish-red fish-flesh-like change. Osteosarcoma is a malignant tumor and is particularly prone to lung metastasis. According to tumor staging, it is at least stage IIB, indicating that it should be detected, diagnosed, and treated early. The earlier the treatment, the better the outcome and the higher the five-year survival rate.
Causes of cervical spondylosis
The causes of cervical spondylosis are actually of two types. The first type is intrinsic causes, which refer to the degeneration of the cervical intervertebral disc, a physiological process. Starting from the age of 20, the cervical intervertebral disc begins to degenerate, varying from person to person; some degenerate faster, others slower. However, as one ages, the cervical discs also gradually deteriorate. The second cause is the pathological changes secondary to the degeneration of the cervical intervertebral discs. For instance, after the discs degenerate, it can lead to instability of the cervical spine, formation of osteophytes around it, calcification of ligaments, and instability of small joints, among others. Due to these reasons, it results in a series of pathological changes affecting nearby soft tissues, such as blood vessels, nerves, spinal cord, and sympathetic nerves. This is the definition of cervical spondylosis. Thus, the causes of cervical spondylosis boil down to two main points: first, the degeneration of the cervical intervertebral discs; second, due to this degeneration, it induces other pathological changes such as the formation of peripheral osteophytes, ligament calcification, joint instability, etc., ultimately compressing the surrounding soft tissues, leading to cervical spondylosis.
