This can't be too certain.
He can only make a comprehensive diagnosis based on the known information and the patient's medical history, age, and nature of work.
Some tests conducted after the patient was admitted show that it should be a single nerve being affected.
Although the patient's palm cannot straighten, there is sensation in the thenar, and the muscle strength of other nerve-controlled muscles in the left upper limb is normal. This indicates that the cause may lie in the radial nerve.
It is not closely related to the musculocutaneous nerve, dorsal nerve, or palmar nerve.
The lesion is now localized in the radial nerve, but the specific cause and other situations remain unknown.
MRI shows that there is no abnormality in the patient's cervical spine, which is a good thing.
The possibility of cervical spine compression or lesion can be basically ruled out.
The spinal nerve should be fine.
