Osteosarcoma diagnostic methods
Osteosarcoma Diagnostic Methods: In clinical practice, once osteosarcoma is suspected in a patient, the diagnostic approach, as per the Chinese Cancer Treatment Guidelines, requires a combination of clinical symptoms, radiological data, and pathology. Only through the integration of these three elements can a definitive diagnosis of osteosarcoma be established. Reliance solely on pathology, or exclusively on radiologic examination or clinical examination, can lead to biased results. Given that immediate treatment is crucial upon the discovery of osteosarcoma, and considering the severe implications of treatment costs, patient suffering, and other related issues, it is vital that the diagnosis of osteosarcoma is error-free. To ensure absolute certainty, the approach should involve clinical symptoms supplemented by necessary auxiliary examinations such as X-rays and CT or MRI scans, followed by a diagnostic biopsy for pathological results. This comprehensive combination generally prevents the occurrence of missed or misdiagnoses in patients with osteosarcoma. Therefore, the confirmatory diagnosis of osteosarcoma should not rely solely on one type of examination but should combine clinical assessment with necessary imaging data and pathology to finalize the diagnosis process.
Which department should I register for sciatica?
Sciatica is divided into primary and secondary types. Primary sciatica is caused by inflammation of the sciatic nerve itself, thus one should visit the Department of Neurology. Secondary sciatica is more common and usually stems from spinal conditions, so initially one should visit the Department of Spinal Surgery. Alternatively, one can visit the Department of Orthopedics, which deals with broader orthopedic issues. If experiencing severe acute pain, a visit to the Pain Management Department can provide rapid and effective pain relief. For frequent episodes of sciatica and interest in rehabilitation, the Rehabilitation Department can be considered. Additionally, traditional Chinese medicine has unique approaches to treating sciatica, so visiting the Department of Traditional Chinese Medicine to try treatments with Chinese herbs and methods is also an option.
Where to apply moxibustion for lumbar disc herniation?
Where to apply moxibustion for lumbar disc herniation. The main acupoint is the Hua Tuo Jia Ji acupoint at the affected intervertebral disc, along with the adjacent Jia Ji acupoints above and below. Additional acupoints are chosen based on different conditions. If there is significant lower back pain, add the acupoint at the affected side's Yaoyan. If there is muscle tension and tenderness in the buttocks, add Huan Tiao and Yi Bian. If there is tension in the hamstring muscles, add Cheng Fu, Yin Men, and Wei Zhong. If there is numbness on the outer side of the thigh, add Feng Shi; if there is numbness in the lower leg, add Wei Yang, Cheng Shan, Yang Ling Quan, Zu San Li, and Xuan Zhong. If there is numbness in the foot and weakness in dorsiflexion, add Tai Xi, Jie Xi, and Xia Xi.
What to check for sciatica
Sciatica is divided into primary sciatica and secondary sciatica. Secondary sciatica is very common and is mainly due to diseases of the spinal canal, including herniated lumbar discs, lumbar spinal stenosis, or spinal tumors compressing the spinal cord and nerve roots. Another condition is piriformis syndrome, where the sciatic nerve exits; if there is narrowing here, it can also cause sciatica. Therefore, clinically, one starts with secondary sciatica, conducting either a lumbar spine CT scan or an MRI, which can basically clarify the location causing the compression. Another type is called primary sciatica, which is caused by inflammation of the sciatic nerve, and is an internal medicine disease, not an orthopedic disease. This requires an electromyography (EMG). After completing the EMG, the diagnosis can generally be made based on the injured muscle or the muscle with abnormal electromotor conduction. Thus, the routine examinations for sciatica are X-rays, CT, MRI, and the non-routine examination is the EMG.
Is a rib fracture serious?
Whether a rib fracture is serious depends mainly on the extent of the fracture and the damage to the surrounding tissues. Generally, a single rib fracture or a non-displaced rib fracture is not serious and requires conservative treatment. However, if there are multiple rib fractures occurring at once, breaking several ribs, including possibly the sixth rib, the consequences can be very serious because it may result in a flail chest. Secondly, a rib fracture can potentially damage surrounding structures such as the pleura, lung tissue, and blood vessels, resulting in conditions such as pneumothorax, pleural effusion, and even active hemothorax, which must be promptly treated to avoid life-threatening situations. Thirdly, if a rib fracture heals in a deformed manner and is not treated, it can compress blood vessels and nerves, causing a persistent type of intercostal neuralgia even after healing. Apart from the local deformity, this situation often stimulates the intercostal nerves and may require surgical intervention. Therefore, the severity of a rib fracture depends mainly on the degree of the fracture and its aftermath, and typically requires assessment by a professional doctor.
Will a comminuted patella fracture cause limping?
Patellar comminuted fractures, as long as treated promptly and correctly, and if the surgery poses no issues, generally heal in about six months, thereby not causing any significant impact. Thus, there's no need to worry about limping. Limping usually means that when walking, one leg appears longer than the other. Under what circumstances can limping occur? If the difference in leg length is within one centimeter, it's imperceptible and won't have any effect. If the difference exceeds two centimeters, then there is a noticeable tilt in the lower limbs, and only then can limping be observed during walking; however, even if limping occurs, it is not severe. It just means that while walking, there is a tilt towards the shorter side. After treatment, patellar comminuted fractures have a complete chance of healing and once healed properly, it's almost like before the injury. Even in severe cases where the fracture is critically fragmented and requires removal, even without patellar replacement, by reinforcing the patellar tendon, it typically does not result in limping. It only impacts the strength in knee extension, possibly creating a mild impediment compared to the other side, and might make walking appear slightly abnormal, but it definitely does not lead to limping. Hence, patellar comminuted fractures do not result in limping.
How long does it take for a triangular ligament injury to heal?
The deltoid ligament, as a very important structure on the medial side of the ankle joint, is mainly divided into superficial and deep layers. The superficial layer generally originates from the anterior colliculus of the medial malleolus and is more superficial, making it more susceptible to injury. The deep layer originates from the posterior colliculus of the medial malleolus and is tightly connected with the talus bone, meaning that any injury likely involved significant force. Moreover, once injured, it cannot self-repair except through surgery. So, how long does it take for a deltoid ligament injury to heal? For superficial injuries, with proper immobilization or surgical repair, recovery typically takes about three weeks. For deep injuries, surgical repair can be challenging, and reconstruction is often required, extending the healing time to about six weeks or even three months.
What are the symptoms of osteoporosis?
What are the symptoms of osteoporosis? Previously there were three categories, but the latest 2017 treatment guidelines have changed it to four categories: First, pain. This mainly manifests as pain in the lower back or pain throughout the bones of the body. Second, spinal deformation. Severe osteoporosis can cause a person to stoop and hunchback, and it can even lead to a decrease in a person's height and cause limited spinal mobility. Third, fractures. Fractures due to osteoporosis belong to the category of fragile fractures. These are fractures that can occur with very low energy or minor trauma. Common sites include the thoracic and lumbar vertebrae, hip fractures, the distal radius and ulna, as well as the humerus and tibia, so sometimes, just a simple fall or being bumped by a door can result in a fracture. Fourth, impacts on psychological states and quality of life. Sometimes after developing osteoporosis, a person may experience fear, anxiety, depression, and loss of self-confidence, which directly leads to reduced contact with the outside world and a decline in the quality of independent living.
Symptoms of tendonitis
The symptoms of tendonitis basically come down to three points. First, pain or a fixed tender point, generally located around joints or nearby areas, with severe cases possibly exhibiting numbness or tingling. Second, dysfunction, which is due to the stiffness of the joint associated with pain which limits joint movement, and occasionally there is mild swelling of the joint. Furthermore, if the tendon pain reoccurs from the originally damaged site and continues for a long time or recurs, it can lead to stiffness in the joint, subsequently resulting in limited joint mobility. The third point is the inflammatory response; tendonitis has specific signs of inflammation, including redness, swelling, heat, pain, and dysfunction.
How to relieve pain from lumbar muscle strain?
Lumbar muscle strain, if the pain is severe, can usually be alleviated using the following methods. First and foremost, during the acute phase, what is primarily needed? First, you need to rest and immobilize, mainly ceasing some activities and ideally lying on a hard bed in a supine position with hips and knees flexed. Secondly, for the painful area, you can apply appropriate physiotherapy. This includes traditional Chinese massage and acupuncture. Thirdly, if there are specific fixed painful points, you might consider blockade therapy. Fourthly, when the pain is particularly severe and affects your work and rest, you can take some non-steroidal anti-inflammatory drugs (NSAIDs). Additionally, use some stimulating medicines or stimulating liniments. If the pain severely impacts your mood and work, you might also consider some sedatives. Fifthly, you can use some external or internal traditional Chinese medicine, which is usually very effective in managing pain.
