Can you explain to me why crushing injury to the occipital bone is often fatal?

Can you explain to me why crushing injury to the occipital bone is often fatal?

Sensitive are: The occipital bone houses the exit of the medulla, which controls functions like breathing & hear rate. It also protects the cerebellum, which coordinates motor function, as well as the visual cortex.. Hemorrhage or crush in these area has a high chance of causing major, irreversible brain injury. They are tight spaces in the brain and do not tolerate swelling/injury etc. ...Read more

Another reason would be too much motion at the fracture site from inadequate immobilization of the fracture. Other medical problems associated with delayed union or nonunion of fracture are diabetes, thyroid disease, corticosteroids, etc. ...Read more

I have pain on the ulnar side of the wrist, close to the tfcc. Mri shows only a bone contusion, no lig damage. The primary injury is 6mo old. What would contribute to contusion lasting this long?

Other causes of Pain: Physical exam is paramount, to determine the origin of the pain. It may be an error to assume, that the cause of the pain, has to be the bone contusion. Depending on the image resolution, partial ligamentous injuries may not be seen, on mri. Correlation with operative (arthroscopic) findings is between 50 to 75 % ...Read more

If sensory nerves are cut while a metal plate is removed from 5th metacarpal bone. What is the common nerve injury ? Is it Axonotmesis or Neurotmesis?

If sensory nerves are cut while a metal plate is removed from 5th metacarpal bone.
What is the common nerve injury ?
Is it Axonotmesis or Neurotmesis?

Nerve injury: Complete transaction of a nerve in the foot as described is neurotmesis.. Partial transaction of only the axon with preservation of the surrounding sheath is axonetmesis. Although the former is more severe of an injury ,many times a complete cut allows for immediate repair and hence quicker recovery. However the effective healing of repaired sensory foot nerves is low so repair is not attempted ...Read more

How much force is usually required to fracture a cervical vertabrae? Can it be broken from normal activity or usually is it high velocity accidents?

Unlikely: It would be extremely unlikely to fracture a cervical vertebrae with normal activities, even in a patient with osteoporosis. I do have patients who come to my office and are told they have a "fractured vertebrae" on their neck X-ray without any history of trauma, but the vast majority of the time the vertebrae is wedge shaped as a developmental abnormality but not fractured. ...Read more

Is it possible for numbness on your skin from a traumatic brain injury to cause an abnormal ecg?

Is it possible for numbness on your skin from a traumatic brain injury to cause an abnormal ecg?

Not directly: Numbness itself won't cause am abnormal eeg. However the damaged area of the brain will. Remember that having a brain injury doesm't mean you don't have other causes of numbness like a nerve compression. Then your eeg would only show changes related to the brain injury. ...Read more

Could a fracture in an infants skull cause swelling and bleeding in the brain?

Could a fracture in an infants skull cause  swelling and  bleeding in  the  brain?

Can co-exist: The skull is separated from the brain by a few tissue layers, & bleeding from the fracture can get between the skull and these layers and cause a problem called an epidural. Epidurals can become large & press on the brain.The event/trauma that caused the fracture can also cause tissue damage in the brain with bleeding & swelling. ...Read more

Had a MRI and it said small bony fragment inferior to the lateral malleolus is either developmental or related to old trauma. What is the meaning.

Had a MRI and it said small bony fragment inferior to the lateral malleolus is either developmental or related to old trauma. What is the meaning.

Nothing bad: From what you wrote it sounds like the radiologist is describing a small fragment of bone at the tip of your fibula ( outer bone of your ankle) this is either a bit of calcification from an old ankle sprain or some people do not fuse the very tip of that bone when they are young and it looks like a loose fragment. These are very common and generally need no treatment unless they are painful. ...Read more
