View detailsBone infection
Bone infection refers to a condition where pathogenic microorganisms spread to the bone tissue through various routes, such as hematogenous dissemination, local open trauma, or nearby infection foci. These microorganisms then reside in the bone, break through the body's defense barriers, and form local infection lesions. It mainly includes diseases such as bone yaws, bone echinococcosis, bone actinomycosis, brucellosis, and syphilis of the bone and joints.
Gluteal muscle contracture
Gluteal muscle contracture refers to the degeneration, necrosis, and hardening of the gluteal muscles, fascia, or aponeurosis caused by various factors. It is common in children and is mainly characterized by restricted hip joint function and pelvic deformity.
View detailsOsteonecrosis
Osteonecrosis refers to the necrosis of living bone tissue components. Factors such as hormones, alcohol, ischemia, infection, and trauma can all lead to osteonecrosis. Osteonecrosis can occur in any part of the human body, with the femoral head being the most common site. The main symptoms of osteonecrosis are pain and joint dysfunction.

Thoracic spinal stenosis is a syndrome of thoracic spinal cord compression caused by a reduction in the cross-sectional area of the thoracic spinal canal. It is more common in middle-aged men, and its etiology is mainly due to acquired degenerative changes and developmental thoracic spinal stenosis. Thoracic back pain, numbness, and weakness in the lower limbs are the main symptoms of this disease.

The cervical spine is located below the head and above the thoracic spine, consisting of 7 vertebrae (labeled C1-C7). Due to its unique anatomical structure, cervical spine fractures, especially those with concomitant spinal cord injury, have a high mortality and disability rate.
View detailsArthralgia
Arthralgia is a common clinical symptom. It can be confined to a single joint or affect multiple joints, and may even be accompanied by systemic complications. The degree of pain is related to the condition. In mild cases, joint discomfort and soreness are only felt after activity, such as after walking long distances, climbing stairs, or lifting heavy objects. In severe cases, the range of motion of the joint may be limited, requiring the patient to remain still, and any weight-bearing on the affected joint can lead to severe pain. There are many causes of arthralgia, which can be classified into degenerative changes, acute and chronic injuries, rheumatic immune diseases, infections, and other causes. The most common causes are degenerative joint aging, acute and chronic injuries, and inflammation.
