Patellar dislocation
Patellar dislocation refers to the condition where the patella slips out of the femoral trochlear groove, typically displacing laterally to the lateral femoral condyle. It primarily affects adolescents, presenting with symptoms such as knee swelling, pain, and difficulty with movement.

Cervical spondylotic myelopathy (CSM) is the most severe type of cervical spondylosis. It is a syndrome caused by degenerative changes in the cervical vertebrae and intervertebral discs, leading to central cervical spinal canal stenosis, compression of the cervical spinal cord, and subsequent spinal cord dysfunction. This condition is more common in middle-aged and elderly individuals, with a higher incidence in males than females. The main symptoms include weakness and instability when walking, increased muscle tone in the limbs, and in later stages, urinary and fecal incontinence, and even paralysis.
View detailsClavicle fracture
Clavicle fracture is the most common shoulder injury, usually referring to the interruption of the integrity and continuity of the clavicle caused by indirect trauma. It is common in adolescents and the elderly. The most common symptoms are swelling, bruising, pain, and deformity at the fracture site.
Poliomyelitis
Poliomyelitis is an acute infectious disease caused by poliovirus infection that invades the spinal cord. It is highly contagious. This disease is common in children under 5 years old, hence it is also known as "infantile paralysis." The vast majority of poliovirus infections are asymptomatic. Some individuals may experience flu-like symptoms, including sore throat, fever, weakness, nausea, headache, and stomach ache. A small number of cases may present with neurological symptoms, including paresthesia (a pins-and-needles sensation in the lower limbs), meningitis (inflammation of the membranes covering the spinal cord and/or brain), hemiplegia, or weakness in the limbs.

Cervical disc herniation refers to a series of clinical symptoms caused by the protrusion of the nucleus pulposus and part of the annulus fibrosus of the intervertebral disc into the surrounding tissues, compressing the corresponding spinal cord, spinal nerve roots, or vertebral arteries. These symptoms include severe pain in one upper limb or hand, neck and shoulder pain, numbness in the limbs, and even paralysis. It is common in young and middle-aged men and the elderly.

The ligamentum flavum, in human anatomy, is a tissue structure that maintains spinal stability. It is located within the spinal canal, is elastic, and exists in segments. This disease is characterized by the ossification of the ligamentum flavum (i.e., its transformation into a bone-like structure), leading to its thickening and hardening. It commonly affects elderly individuals and often presents as lower back pain, which may be relieved or disappear after rest.
View detailsPiriformis syndrome
Piriformis syndrome is a set of symptoms caused by the piriformis muscle in the buttocks compressing the underlying sciatic nerve. However, due to the lack of objective evidence and reliable assessment methods, this diagnosis remains controversial. This condition is common in people with a history of buttock trauma or prolonged sitting, and it is more prevalent in women than in men. The main symptoms include pain in the affected buttock and radiating pain down the leg.
View detailsSpinal deformity
Spinal deformity refers to structural and positional abnormalities of the human spine in the anterior-posterior, left-right, or superior-inferior directions. Common types include kyphosis and scoliosis. Patients with spinal deformities may exhibit abnormal spinal curvature in their appearance. Additionally, spinal deformities can lead to difficulty bending and straightening the back, and impaired lower limb mobility.
View detailsAneurysmal bone cyst
Aneurysmal bone cyst is a benign solitary bone tumor, a tumor-like lesion of bone morphology and manifestation, and a solitary, expansive, hemorrhagic, multilocular cyst. In layman's terms, it is a lump on the body that continuously grows and bleeds. This disease is common in people aged 11-30, with males more affected than females. The main symptoms are gradually worsening localized pain and swelling of the limbs.
