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.
How long after a patellar comminuted fracture can one start walking?
Patellar comminuted fractures generally require surgical treatment. If the surgery goes well, patients can start moving around with the aid of crutches one week after the surgery. Initially, changing positions is not allowed. Generally, patients can start by placing the toes on the ground two weeks post-surgery, followed by the middle part of the foot, and finally the heel. This progression occurs from two to six weeks after the surgery.
How to treat cervical spondylosis?
The treatment of cervical spondylosis is symptomatic, and it is first necessary to determine the type of cervical spondylosis, and then treat it according to its classification. Cervical type cervical spondylosis usually does not require surgery and can be managed with conservative treatment. Nerve root type cervical spondylosis is the most common type seen in clinical practice and responds particularly well to traction therapy. Additionally, oral non-steroidal anti-inflammatory drugs and nerve nutrients can also be used. Spinal cord type cervical spondylosis usually cannot be managed conservatively, or may require surgery after a short period of conservative treatment. This type is the most frequently operated on in clinical practice for cervical spondylosis. The fourth type is the sympathetic nerve type cervical spondylosis, which is very complex to diagnose. It often causes some internal system diseases, such as high blood pressure or heart disease. However, these conditions often improve as the cervical spondylosis improves. The fifth type is vertebral artery type cervical spondylosis, which typically causes symptoms of insufficient cerebral blood supply. Therefore, treatment of cervical spondylosis also requires addressing arteriosclerosis. Mixed type cervical spondylosis refers to the simultaneous occurrence of two types of cervical spondylosis, and treatment involves managing both types concurrently. Thus, the treatment of cervical spondylosis first requires determining the specific type you have and then carrying out symptomatic treatment for that specific type.
Can tendinitis be treated with a cortisone injection?
Can a cortisone injection be used for tendinitis? From a clinical perspective, for tendinitis, other conservative treatments such as physical therapy, massage, and oral medications can be used. When treatments like phototherapy are ineffective or not yielding results, a cortisone injection is certainly an option. As long as it is accurately targeted, the results of a cortisone injection are very satisfactory. In some cases of tendinitis, a cortisone injection can even achieve a curative effect. Thus, after tendinitis, a cortisone injection can definitely be used for treatment.
