Introduction
In general, crossing the legs in a scissor-like manner may be caused by conditions such as cerebral palsy, avascular necrosis of the femoral head, or multiple sclerosis. In addition, other causes such as syringomyelia, spinal cord vascular diseases, myelitis, or hereditary spastic paraplegia may also lead to this symptom. Patients are advised to seek medical attention promptly when experiencing discomfort to avoid delays in treatment, and should maintain a light, healthy diet in daily life.

In general, crossed legs resembling scissors may be caused by conditions such as cerebral palsy, avascular necrosis of the femoral head, or multiple sclerosis. Specific details are as follows:

1. Cerebral Palsy

This condition results from non-progressive brain damage occurring during fetal or infant development and may be accompanied by abnormalities in sensation, perception, cognition, behavior, and seizures. In young children presenting with scissor-like leg crossing, this condition should be considered first. Parents should enhance care, pay attention to nutrition and hygiene, and work with doctors who will develop individualized rehabilitation plans based on the child's current abilities. The goal is to maximize functional improvement. During rehabilitation, orthotic devices or assistive equipment are often used to help correct abnormal postures.

2. Avascular Necrosis of the Femoral Head

This is a common and difficult-to-treat orthopedic condition. Its onset is associated with various factors such as trauma, long-term corticosteroid use, and alcohol intoxication. Main symptoms include hip and thigh pain, limping, and limb shortening deformities, which may lead to scissor gait. Patients may consult their physicians regarding surgical treatment options such as core decompression, osteotomy, or total hip arthroplasty.

3. Multiple Sclerosis

This is a chronic inflammatory demyelinating disease of the central nervous system mediated by immune mechanisms, affecting areas such as the spinal cord, brainstem, and cerebellum. Clinical manifestations are diverse and may include limb weakness, sensory disturbances, vision loss, and scissor gait. Patients are advised to follow medical instructions and use medications such as methylprednisolone tablets or azathioprine tablets for treatment.

Besides the above, other possible causes include cerebrovascular diseases, spinocerebellar ataxia, syringomyelia, spinal vascular diseases, poliomyelitis, and hereditary spastic paraplegia. It is recommended that patients seek timely medical evaluation when experiencing symptoms to avoid delays in treatment. Additionally, maintaining a light diet and adequate rest is important in daily life.
