The difference between tendinitis and tenosynovitis
Actually, tendinitis and tenosynovitis are essentially two aspects of the same condition. The term tendinitis usually refers to the part where the muscle transitions into the tendon, whereas tenosynovitis generally refers to the fibrous sheath over the tendon surface. Thus, tendinitis and tenosynovitis often coexist; tendinitis can lead to tenosynovitis, and conversely, tenosynovitis can also affect tendinitis, causing or exacerbating it. Therefore, in clinical practice, there usually is not a clear distinction between tendinitis and tenosynovitis. It is common during surgeries for stenosing tenosynovitis to observe that the tendon is also congested and swollen, and even adhered to the tendon sheath. Thus, tendinitis and tenosynovitis are generally considered the same disease, merely referred to by two different names. However, if strictly distinguished, there is a certain difference, which lies in the location: tendinitis refers to the tendon itself, while tenosynovitis refers to the sheath outside the tendon.
How to treat patellar ligament injury?
First, it is necessary to qualitatively assess the injury of the patellar ligament, determining whether it is a partial or complete rupture, whether it is a simple rupture, or a compound rupture, the latter involving other injuries such as fractures or joint dislocations. The treatment of patellar ligament injuries, like other tendon injuries, follows the principle of "three earlies": early diagnosis, early treatment, and early rehabilitation. Early diagnosis has been mentioned before. Early treatment means that if surgery is needed, it should be conducted as soon as possible, as earlier surgeries often result in better postoperative recoveries. If surgery is not required, an immediate fixation with a cast or brace should be applied to keep the knee joint in an extended position, and this fixation should be maintained for three to four weeks. The third step is early rehabilitation. As the knee joint is immobilized during the fixation period, and pain and swelling starts to decrease, early functional exercises should be initiated, focusing on distal joint movement and muscular isotonic exercises, but avoiding flexion and extension movements of the knee joint. Early rehabilitation primarily aims to prevent muscle atrophy, prevent joint adhesion, and promote recovery from the condition.
Can osteosarcoma be detected by X-ray?
Osteosarcoma can be detected with an X-ray, which is a very important method for diagnosing osteosarcoma. Since osteosarcoma typically comes in three types—osteoblastic, osteolytic, and mixed—the appearances on the X-rays are generally different. Osteolytic osteosarcoma mainly involves bone destruction, osteoblastic is characterized by bone regeneration, and the mixed type has both bone destruction and regeneration. Secondly, osteosarcoma primarily erodes the bone quality, and the periosteal reaction is very apparent. Typical osteosarcomas often show signs like Codman's triangle or the sunburst appearance. Therefore, if symptoms such as redness and increased temperature of the skin, along with a bony lump, occur around the distal femur, proximal tibia, or proximal humerus, it is best to first go to the hospital for an X-ray. X-rays are currently the most economical and necessary diagnostic tool for osteosarcoma.
How to treat shoulder tendinitis?
Shoulder tendinitis is commonly seen in supraspinatus tendinitis, infraspinatus tendinitis, and long head of the biceps tendinitis. The treatment is mainly conservative. During the acute phase of tendinitis, resting, immobilization, and wearing protective gear are recommended. Secondly, oral intake of non-steroidal anti-inflammatory drugs can be considered. Thirdly, traditional Chinese medicines can be taken orally or applied topically. Fourthly, injection therapy can be considered, which usually has good effects. Fifthly, physical therapy is an option, including heat therapy and microwave therapy, with a special recommendation for shockwave therapy, which is very effective for tendinitis throughout the body. If conservative treatment is ineffective, surgical treatment may be necessary, tailored to the specific tendon involved.
What are the symptoms of osteosarcoma?
Osteosarcoma is a very common malignant tumor, primarily occurring at the distal femur, proximal tibia, and proximal humerus. Its manifestations mainly include persistent pain at these three locations, which gradually worsens and is accompanied by nighttime pain. Secondly, there is local swelling; the surface of the tumor may feel warmer to the touch and may even exhibit prominent veins, leading to restricted joint movement near the tumor. Thirdly, some patients may exhibit signs of systemic deterioration, such as weight loss, anemia, and fatigue. Fourthly, osteolytic osteosarcomas often erode the bone cortex, eventually weakening the bone and leading to pathological fractures. Thus, the symptoms of osteosarcoma include persistent pain in specific areas accompanied by nighttime pain, local swelling, systemic deterioration, and pathological fractures in many patients.
Precautions for Lumbar Disc Herniation
For patients with lumbar disc herniation, self-prevention and self-treatment are very effective methods. What should be paid attention to in daily life? The first point is to maintain a correct sitting posture, sit upright, do not lean back, and avoid sitting for long periods. It is also necessary to keep the waist warm and prevent it from getting cold. The second point is to engage in some exercises, mainly those that strengthen the muscles of the lower back, such as large swallow flight, small swallow flight, single bridge, and double bridge. The third point is that in daily life, it is important to pay attention to maintaining the correct posture when working, avoiding putting too much pressure on the lumbar spine, and not using brute force. The fourth point is that in terms of rest, it is best to sleep on a hard bed and add a small pad at the waist or a soft pillow under the knee joints. This can keep the knee and hip joints at a certain degree of flexion, allowing the muscles of the lower back to fully relax. The fifth point is to wear a waist brace under the guidance of a doctor. This waist brace is a very common orthopedic support, which functions to immobilize and protect the waist. Moreover, for patients with lumbar disc herniation, it can greatly increase the stability of the lumbar spine and consolidate the effects of previous treatments. Therefore, patients with lumbar disc herniation must pay attention to these details in daily life.
What is lumbar muscle strain?
What is lumbar muscle strain? Lumbar muscle strain refers to the cumulative injury of muscles and fascia in the lumbar region caused by long-term unbalanced postures or incorrect positions during labor. It is one of the common causes of lumbar pain. How to understand this definition? Lumbar muscle strain is first and foremost a cumulative injury. What causes it? First, incorrect postures—sitting straight is necessary. Slouching or hunching over, especially when idle, or sitting askew, is detrimental. Second, certain types of labor, like that of miners or farmers transplanting rice, consistently place the lower back in an imbalanced state, perpetually bending forward. This day-to-day accumulation leads to lumbar muscle strain.
How to treat the symptoms of tendinitis
The symptoms of tendinitis firstly include pain, which develops from mild to severe and can be alleviated by rest. However, the pain reoccurs or escalates with physical activity or increased intensity of movement. Additionally, the greater the activity, the shorter the relief period. The second symptom is restricted movement primarily due to pain. Pain causes limitations when moving the limb in certain ways or directions, increasing the pain and thereby causing movement restrictions. Typically, tendinitis presents a fixed tender point usually located at the site of injury, with possible radiating pain around the tender point. Swelling is generally not prominent; the primary characteristic of tendinitis is severe pain, with no significant changes in the skin and minimal or very light swelling. As for treatment, conservative approaches are commonly chosen, such as standard treatments involving immobilization, rest, and protecting the affected area. Oral non-steroidal drugs might be used along with localized treatments, or physical therapies like microwave and shockwave therapies, which are quite effective. If symptoms do not improve or worsen despite rigorous conservative treatment, surgical intervention may be necessary. The specific surgical techniques vary and are determined by the surgeon.
What department should I see for a lumbar disc herniation?
For herniated lumbar discs, you should visit either the Department of Spine Surgery or Orthopedics. The specific department depends on the hospital you choose to visit. If the hospital is a high-level institution, grade three or above, it will certainly have a Department of Spine Surgery, so this would be the first choice. However, if the hospital is a community clinic or a second-tier hospital, it might not have a Spine Surgery department, so you would need to visit the general Orthopedics department. Although herniated lumbar discs are a common orthopedic condition and can be treated in Orthopedics, visiting a specialist in Spine Surgery can often provide more expert care as these doctors may have higher levels of experience and expertise in treatment.
Treatment of Tendonitis
The causes of tendinitis usually fall into the following three categories: The first is acute injury, commonly referred to as tendon strain. The initial step is to stop any activity, followed by immobilization of the affected tendon area. Immobilization typically involves allowing the part to be completely relaxed, under no pressure, and is usually for a period of three weeks. The second cause is chronic overuse, which is the most common reason for tendinitis. It frequently occurs at sites of bony protrusions or where there is a tunnel, and this can easily lead to constrictive tendinitis. Treatment might start with rest, followed by non-steroidal anti-inflammatory drugs if rest is ineffective. Then, injection treatments are considered, typically around three times; symptoms or pain from tendinitis will significantly reduce or even disappear. If there is no improvement after three injections, a fourth should not be attempted, and surgical treatment to release the tendon and alleviate the constriction may be considered. The last cause is due to a purulent infection. This condition requires symptomatic treatment, initially with antibiotics, followed by cultures and sensitivity tests of the effusion. If the infection occurs adjacent to the tendon or in the tendon sheath, surgery might be necessary to perform drainage again. In summary, the treatment of tendinitis largely depends on the specific cause and involves different approaches.
