Hazards of Rib Fractures
The most severe case of rib fracture is what we call the occurrence of pneumothorax. Pneumothorax is caused by the puncture of the pleural cavity due to the fractured end, resulting in pneumothorax or hemothorax compressing the lung tissue, causing severe systemic respiratory and circulatory disorders. Severe pneumothorax can directly endanger life; this is the most serious harm of rib fractures. However, generally speaking, it is rare for a rib fracture to result in severe pneumothorax; most cases involve only a small amount of effusion or a small amount of air accumulation. Thus, generally, the harm from rib fractures is not very significant; the most severe harm is causing severe pneumothorax, affecting the overall respiratory and circulatory functions, and endangering life.
How long is the latent period of osteosarcoma?
In clinical practice, there is no such thing as a latency period for malignant bone tumors, because these tumors progress very quickly. So, if you experience symptoms such as swelling and pain in the affected limb, if you can feel a mass, and if the pain severely impacts your daily life, you should promptly go to a hospital to get an imaging test done to determine whether a bone tumor is present. Only through imaging and accurate diagnosis can early diagnosis and treatment be achieved, which is the best treatment approach for osteosarcoma. Therefore, in clinical practice, there is no concept of a latency period for malignant bone tumors.
How to treat tendinitis and synovitis?
How to treat tendinitis and synovitis? Generally, the current approach is to first start with conservative treatments for tendinitis and synovitis. Conservative treatments include acupuncture, massage, physical therapy, topical ointments, and oral medications, all of which can help alleviate the symptoms of tendinitis and synovitis. However, if there is no improvement after more than six months of treatment, or if the symptoms, such as increasing pain, worsen, then a minimally invasive surgery might be necessary to provide relief.
Symptoms of toe fracture
The symptoms of a toe fracture primarily include pain, swelling, and limited mobility. If there is a noticeable displacement of the fracture ends, a typical deformity can also occur. For the treatment of toe fractures, conservative treatment such as casting or using a brace may be sufficient if it is a simple linear fracture without significant misalignment of the fracture ends. However, if there is substantial shortening, rotation, separation, or if the fracture is comminuted, surgical treatment is required. During surgery, the fracture ends are repositioned through an incision. After repositioning, a Kirschner wire is used to internally fixate the fracture ends, allowing the bone to heal in the proper alignment without leaving any deformity. This describes the surgical treatment method.
What are the symptoms of osteosarcoma?
Symptoms of Osteosarcoma: The first is pain at the site of occurrence. This pain may be intermittent and not very pronounced in the early stages. As the condition progresses, the severity of the pain gradually increases, transitioning from intermittent to persistent pain; The second is the formation of a lump. You can feel a lump on the limb with your hand, and this lump is clearly tender to the touch; The third is limping, which is mainly caused by the pain in the limb; The fourth is the most common systemic symptoms. Patients with this malignant tumor will exhibit fever, weight loss, anemia, and pathological fractures. These are the main symptoms of osteosarcoma currently observed in clinical settings.
What should I do if I have a knee ligament injury?
Ligament injuries in the knee are commonly seen in two areas: the first is the anterior cruciate ligament (ACL) injury, and the second is the medial collateral ligament (MCL) injury. The treatment for these two ligament injuries is the same; for instance, in cases of just a simple ligament tear or partial tear, it only requires the use of a plaster cast for external fixation, and immobilization for three to four weeks can achieve recovery. If there is a complete tear, surgery might be needed. There are two types of surgeries: the first one involves direct repair of the ligament, the second involves using autologous tendons to reconstruct the ligament, restoring the stability of the entire knee joint. To determine whether you have a tear, complete tear, or partial tear, it is necessary to undergo an MRI of the knee to confirm.
What are the symptoms of lumbar disc herniation?
The early symptoms of lumbar disc herniation mainly include back pain and limited mobility. With appropriate conservative treatment at this stage, the symptoms will not worsen. For example, sleeping on a hard bed, resting adequately, and using some physical therapy methods can help alleviate back pain and restricted mobility. If back pain and mobility limitations occur and are not treated correctly, it may lead to mid-to-late-stage symptoms. The patient will typically experience sciatica, with radiating pain and numbness in both lower limbs, caused by the herniated disc compressing the nerve root, leading to impaired nerve function and symptoms of numbness and pain in the lower limbs.
Do benign osteosarcomas use chemotherapy?
First of all, all osteosarcomas are malignant; osteosarcoma is a type of malignant tumor with no benign variant. Regarding the treatment of osteosarcoma, the first step is chemotherapy. After confirming the diagnosis through pathological examination and confirming it is osteosarcoma, The first step is chemotherapy, which can stabilize the tumor cells; Then, the main tissue is surgically removed, as well as the surrounding infiltrated soft tissue; The third step is to use chemotherapy again to eliminate the residual cancer cells. This treatment protocol of chemotherapy-surgery-chemotherapy is currently the most common and advanced method in the country. It can significantly improve the patient's survival rate, reduce the risk of amputation, and can also prevent the recurrence of osteosarcoma.
The common sites of osteosarcoma
Osteosarcoma commonly occurs in the long tubular bones of the limbs, such as the femur, tibia, and humerus, especially near the joints of these long bones where the incidence is highest. In children, the distal femur and proximal tibia account for about three-quarters of all bone tumors. Osteosarcoma can also occur in the proximal humerus, the spine, and the ribs, although it is less common in these locations. The most frequent sites remain the long tubular bones in the limbs.
What are the symptoms of a fracture?
After a fracture, three characteristic manifestations occur. The first one is abnormal movement. This abnormal movement is due to the formation of an unusual activity of the fracture ends in the affected limb, known as abnormal movement. The second one is called deformity, which is also due to a significant deformity in the affected limb after the fracture ends. The third one is called bone crepitus, also known as bone rubbing sound, which is the sound produced when the fracture ends rub against each other. These three are specific signs of a fracture. In addition to these three, there will also be severe pain in the affected limb, and this pain is very intense, rendering the limb immobile. Secondly, there will be obvious swelling, which is caused by bleeding in the medullary cavity of the fracture ends. The third is functional impairment, as the affected limb will definitely be immobile after the fracture.
