How is osteoporosis treated?
Osteoporosis refers to a decline in bone density and quality, increasing brittleness and potentially leading to systemic skeletal diseases. Once osteoporosis occurs, it is crucial to appropriately supplement inorganic salts that promote bone formation, as the structure composed of inorganic salts and collagen in the bones changes. Dietary intake should be enhanced with foods rich in calcium, and it is equally important to supplement with Vitamin D, as the absorption of calcium is facilitated by Vitamin D. Therefore, not only should calcium be supplemented, but also Vitamin D should be appropriately added. Alongside supplementing calcium and Vitamin D, proper exercise is important, as increased physical activity can help strengthen the bones. If these measures do not alleviate the condition, it may be necessary to investigate whether the issue stems from an obstruction in bone formation or from a problem with bone loss. Determining the cause of osteoporosis in this way, there are also medications available that can alleviate bone loss and promote bone formation, allowing for targeted treatment.
Can I run with lumbar muscle strain?
The occurrence of lumbar muscle strain is mainly due to chronic injury causing excessive fatigue of the muscles, resulting in muscle fiber strain. Lumbar muscle strain is primarily a type of chronic aseptic inflammation, characterized by symptoms such as pain and restricted movement. When lumbar muscle strain occurs, it is not advisable to continue running; instead, it is recommended to apply heat and rest. This is because running can exacerbate the load on the lumbar region, which is not very beneficial for lumbar muscle strain. Therefore, when lumbar muscle strain occurs, rest and appropriate physical therapy should be the main focus.
The difference between tendinitis and tendon sheath cyst.
Tendinitis refers to the inflammation of a sheath surrounding the tendon, known as the tendon sheath, caused by chronic strain. This results in a sterile inflammatory response between the tendon and its sheath, leading to symptoms such as pain and limited mobility. Meanwhile, a tendon sheath cyst is a cystic change occurring within the tendon sheath due to various reasons, characterized by a small amount of fluid or gel-like tissue within the cyst. When tendinitis occurs, it can be managed with conservative treatment, rest, and physical therapy to alleviate symptoms. On the other hand, a tendon sheath cyst might not show evident symptoms initially, but as the condition progresses and the cyst grows, it may compress local blood vessels or nerves causing symptoms, necessitating surgical intervention at this stage.
How to recover from collateral ligament injury of the knee joint
The knee joint has important ligaments on both the inner and outer sides, known as the medial collateral ligament and the lateral collateral ligament. In sports injuries, collateral ligament damage of the knee is very common. If there is an injury, the first step is to conduct a series of examinations to determine the stability of the knee joint. The damage to these ligaments can range from tears to complete ruptures. If there is only a contusion or a tear, the knee can recover its function through the use of supportive braces and the natural healing of the ligament. However, if the collateral ligament is completely ruptured, surgery is necessary for repair. The specific extent of the damage needs to be determined by MRI and physical examinations to decide the best treatment approach for the patient's recovery.
Post-traumatic sequelae of femoral head comminuted fracture
A comminuted fracture generally refers to a fracture with more than three fragments. When a comminuted fracture occurs in the femoral head, it is also a type of intra-articular comminuted fracture. Generally speaking, after the fracture is reduced and stabilized, there can be some damage to the joint surface as well, leading to unevenness of the joint surface and a higher chance of developing postoperative traumatic arthritis. There is also a possibility that the comminution of the femoral head fracture could affect the blood supply to the femoral head, leading to ischemic necrosis of the femoral head. After treatment for the fracture injury, there will inevitably be some impact on postoperative function. Therefore, after a comminuted fracture of the femoral head, the first sequelae to appear is usually traumatic arthritis, followed by ischemic necrosis of the femoral head, and thirdly, symptoms of restricted movement in the hip joint may occur.
What medicine is used for tenosynovitis?
Tendinitis refers to the inflammation of the tendon sheath around the tendon due to repeated motion and strain, resulting in symptoms such as pain and limited mobility. In the early stages, the inflammation is relatively mild and conservative treatments can be chosen, such as the topical application of non-steroidal anti-inflammatory and analgesic medications to alleviate local pain and reduce inflammation. Physical therapy can also be used to promote healing of the injury. If the symptoms are severe and there is a snapping symptom, medication alone may not resolve the condition, and surgical treatment may be necessary.
How to care for a patellar fracture
A patellar fracture occurs, the first step is to immobilize the patellofemoral joint. During treatment, the primary goal is to prevent the formation of lower limb thrombosis. Therefore, early on, patients can be actively guided to contract the quadriceps and calf triceps muscles, while also performing dorsiflexion and flexion exercises of the ankle joint to avoid ankle stiffness. As the condition stabilizes, a cushion can be placed under the knee joint to allow for active flexion of the knee. If the fracture has stabilized, the patient can sit at the edge of the bed and let the knee naturally flex downward. If there is difficulty, the healthy limb can be used to help push and squeeze the injured limb to achieve a flexion close to ninety degrees. Patients can also lie in bed, hug their thighs with both hands, and flex the knee joint beyond ninety degrees to enhance this type of knee exercise.
Does bone hyperplasia hurt?
Bone hyperplasia commonly arises due to degenerative changes in the elderly, especially at the sites where muscles and tendons attach, leading to abnormal bone growth. This can cause localized pain and restricted movement. For instance, bone hyperplasia around the knee joint, patella, and on one side of the tibial plateau in the knee joint can cause repeated friction against surrounding ligaments and tendons, leading to painful symptoms, as well as joint deformities. Thus, bone hyperplasia is associated with some painful symptoms.
What is lacking in osteoporosis?
Osteoporosis refers to a systemic bone disease characterized by an imbalance in the mineral content within bone structures, such as calcium and phosphorus, as well as the bone matrix, such as collagen, leading to decreased bone hardness and damage to the bone's microstructure. This structural change results in increased brittleness, thereby raising the risk of fractures. It is primarily caused by a disruption in the normal proportional relationship between inorganic salts and the bone matrix, generally due to the loss of inorganic salts like calcium and phosphorus.
Which department should I visit for sciatica?
Pain in the sciatic nerve first requires a visit to orthopedics or spinal surgery to look into whether the pain is caused by a herniated disc compressing the nerve root. If examinations or imaging studies find no abnormalities, we might consider the possibility of piriformis syndrome, or other reasons causing the nerve pain. You can then consult the pain management department to determine the cause and receive appropriate treatment, primarily involving orthopedics and pain management.
