Differentiated diagnosis of cervical spondylosis
The differential diagnosis of cervical spondylosis should be described according to the four types of cervical spondylosis. First, for myelopathic cervical spondylosis, the differential diagnosis mainly includes amyotrophic lateral sclerosis and syringomyelia. Second, for radicular cervical spondylosis, the differential diagnosis primarily involves distinguishing it from thoracic outlet syndrome, cubital tunnel syndrome, radial tunnel syndrome, and ulnar tunnel syndrome. These syndromes are all characterized by localized bony or fibrous entrapment of nerves, whereas the compressive factors in radicular cervical spondylosis include herniated cervical discs and hyperplastic uncovertebral joints. This can be confirmed through physical examination, radiological analysis, and electromyography. Third, for vertebral artery type cervical spondylosis, it should be differentiated from vestibular disorders, cerebrovascular disease, and eye disorders, while also excluding Ménière's syndrome. Fourth, for sympathetic cervical spondylosis, cardiovascular and cerebrovascular diseases should be excluded. X-ray imaging of the cervical spine in dynamic positions may initially reveal cervical instability.
osteosarcoma X-ray presentation
The variations in the X-ray appearance of osteosarcoma are quite large, but the basic characteristics are a mix of osteolytic destruction and pure bony changes. In most cases, besides the mixed changes, there is also destruction of the bone cortex and invasion of soft tissues, with visible periosteal reaction. The epiphysis has a certain blocking effect on the tumor, hence it rarely crosses the epiphyseal line. On the X-ray, changes indicative of skip metastasis can be seen, along with typical Codman's triangle or sunburst patterns. Beneath the periosteum, there are fine, needle-like sunburst radiating changes, which are fairly typical radiographic changes of osteosarcoma and are generally used to diagnose the condition.
What does a fracture feel like?
The feeling of a fracture, first and foremost, the most important clinical manifestation is pain. Of course, the intensity of the pain is related to the type of fracture. Generally, incomplete fractures or greenstick fractures are not as painful, but if the fracture is displaced, comminuted, or other types, the pain is more pronounced. The second manifestation is swelling; the area of the fracture will show obvious swelling and become quite enlarged. The third is tenderness, which means that touching or pressing on the area will result in noticeable pain. Fourth, there is a significant restriction of movement in the joints adjacent to the fracture site.
