Chronic osteomyelitis
Chronic osteomyelitis is a chronic inflammatory process caused by bacterial infection, accompanied by bone destruction. It is more common in young and middle-aged men, and is mainly characterized by ulceration and pus discharge in the affected limb, accompanied by local skin and soft tissue edema and pigmentation.
View detailsOsgood-Schlatter disease
Osgood-Schlatter disease, primarily seen in adolescents during their growth spurt, is caused by rapid growth, immature and unstable bones, and repeated traction or trauma, leading to epiphysitis. It mainly presents as swelling and pain below the knee. Most patients recover spontaneously after skeletal maturity or by ceasing strenuous activities.

The tibial nerve is a major branch of the sciatic nerve and is rarely injured in isolation. However, in cases of supracondylar femoral fractures or knee dislocations, tibial nerve injury may occur, manifesting as weakness or inability to plantarflex the ankle and toes, atrophy of intrinsic foot muscles, toe deformities, and diminished or absent sensation in the sole of the foot.
Acromioclavicular joint dislocation
The acromioclavicular joint is formed by the lateral end of the clavicle and the acromion. It is stabilized by the joint capsule, acromioclavicular ligaments, and coracoclavicular ligaments. When the acromioclavicular joint is subjected to violent trauma, and the joint capsule, acromioclavicular ligaments, and coracoclavicular ligaments are damaged, it can lead to acromioclavicular joint dislocation. Clinically, symptoms often include shoulder pain, swelling, and limited shoulder joint movement. Clinically, there are three types of acromioclavicular joint dislocation based on the condition of the acromioclavicular ligaments, coracoclavicular ligaments, and the degree of dislocation. Type I: Acromioclavicular joint capsule and ligaments are sprained but not ruptured. Type II: Joint capsule rupture, partial ligament tear, and subluxation of the joint. Type III: Joint capsule rupture, complete ligament tear, and dislocation of the joint.
View detailsSympathetic cervical spondylosis
Sympathetic cervical spondylosis refers to a series of symptoms caused by the stimulation of the sympathetic nerves due to lesions in the cervical nerve roots, posterior longitudinal ligament, facet joints, vertebral arteries, dura mater, and other tissues. This disease is common in young and middle-aged people. The main symptoms include headache, dizziness, blurred vision, nausea, and vomiting.
View detailsPhantom limb pain
Phantom limb pain (PLP) refers to the phenomenon where patients subjectively feel the presence of a removed limb after amputation and experience severe pain. It is one of the most common postoperative complications in amputees. Research data show that the incidence of phantom limb pain after amputation is approximately 42.2% to 78.8%. The two peak periods for the onset of phantom limb pain are within 1 month after amputation and after 1 year.

Legg-Calvé-Perthes disease, also known as Perthes disease or flat hip, is a self-limiting, avascular disease characterized by partial or complete necrosis of the femoral head epiphysis due to impaired blood supply to the femoral head from various causes. After healing, the femoral head often presents with a flattened deformity, hence the name "flat hip."
View detailsFemoral nerve entrapment syndrome
Femoral nerve entrapment syndrome refers to the narrowing of the sheath along the femoral nerve's pathway, leading to compression of the femoral nerve and resulting in corresponding symptoms and signs. The most typical and primary symptoms of femoral nerve entrapment syndrome include sudden, severe pain at the root of one thigh, a feeling of local fullness, inability to straighten the thigh (remaining in a flexed state), followed by numbness and decreased sensation in the anterior part of the thigh and medial side of the calf, weakness in leg extension, weakness in the anterior thigh muscles, and diminished or absent knee reflex.
View detailsFemoral nerve injury
The femoral nerve is composed of lumbar nerve roots L2-L4, innervating the quadriceps femoris and sartorius muscles. Lesions along its course can easily lead to femoral nerve injury. Symptoms mainly include sensory disturbances in the anterior thigh and medial calf, diminished or absent patellar reflex, inability to extend the knee joint, and quadriceps femoris atrophy.
