Which type of fracture typically occurs at the base of the skull?

A basilar skull fracture is a break of a bone in the base of the skull. Symptoms may include bruising behind the ears, bruising around the eyes, or blood behind the ear drum.

What is the effect of an enlarging brain abscess?

Some longterm effects following brain abscess resolution include seizures, loss of mental acuity, and focal neurological deficits that are likely attributed to the loss of neurons during infection.

What is the typical initial effect of a herniated intervertebral disc at the L4 to L5 level?

The most common levels for a herniated disc are L4-5 and L5-S1. The onset of symptoms is characterized by a sharp, burning, stabbing pain radiating down the posterior or lateral aspect of the leg, to below the knee. Pain is generally superficial and localized, and is often associated with numbness or tingling.

What is the primary reason for seizures frequently occurring with head injuries?

Seizures which occur more than a week after a traumatic brain injury are considered late seizures. Most often when this happens, it is because there has been more serious injury to brain cells and the chemical environment around the cells has also changed.

Where is sphenoid bone?

The sphenoid is an unpaired bone. It sits anteriorly in the cranium, and contributes to the middle cranial fossa, the lateral wall of the skull, and the floor and sides of both orbits. It has articulations with twelve other bones: Unpaired bones – Occipital, vomer, ethmoid and frontal bones.

What is hinge fracture?

Hinge fractures are defined as crushing injuries, such as compression of the head between the ground and a heavy object (ie, a car tire). 1,17,18. Transverse hinge fractures extend across the dorsum sellae of the skull, and can separate it into two.

What causes L2 L3 pain?

For example, if you have a bulging disc between the 2nd and 3rd lumbar vertebra (L2-L3), and it pinches the L2 nerve root, you may experience back pain with aching, burning or shooting pain, numbness and tingling in the thigh, sometimes going down into the lower leg or foot.

What is disc herniation in lumbar spine?

A herniated disc occurs when the gel-like center of a disc ruptures through a weak area in the tough outer wall, similar to the filling being squeezed out of a jelly doughnut. Back or leg pain, numbness or tingling may result when the disc material touches or compresses a spinal nerve.

Which lumbar disc is most commonly herniated?

The L5-S1 disc is between the 5th lumbar and 1st sacral bones. These two discs do the most work and are the most frequently injured.

How can you tell the difference between a brain abscess and meningitis?

Meningitis is defined by the presence of the inflammation of the meninges, with characteristic changes in cerebrospinal fluid. Brain abscess is a focal infection of the brain parenchyma, commonly caused by bacterial, fungal, and parasitic pathogens.

What causes brain abscesses?

What causes a cerebral abscess? A cerebral abscess usually occurs when bacteria or fungi make their way into your brain, either through your bloodstream or from an infected area in your head, such as your ears or sinuses. An injury to your head or head surgery can also let in germs that can cause an abscess.

What antibiotics treat brain abscess?

Treat all brain abscesses with antibiotics (usually initially with ceftriaxone or cefotaxime plus metronidazole if clinicians suspect Bacteroides species or plus vancomycin if they suspect S. aureus), typically followed by CT-guided stereotactic aspiration or surgical drainage.

What are the 4 types of seizures?

It causes seizures, which are bursts of electricity in the brain. There are four main types of epilepsy: focal, generalized, combination focal and generalized, and unknown. A person’s seizure type determines what kind of epilepsy they have. Different types of seizures affect the brain in different ways.

What is the most common type of seizure?

The most common type of seizure is the complex partial seizure. This is a seizure that begins in one part of the brain and then spreads to other regions of the brain.

What are the 3 types of seizures?

• Generalized onset seizures:
• Focal onset seizures:
• Unknown onset seizures:

What is Jefferson fracture?

A Jefferson fracture is a bone fracture of the vertebra C1. The vertebra C1 is a bony ring, with two wedge-shaped lateral masses, connected by relatively thin anterior and posterior arches and a transverse ligament. The lateral mass on vertebra C1, who is taller, is directed laterally.

What is Undertaker fracture?

Undertaker’s fracture is an artifact related to poor handling of the corpse characterized by subluxation of the lower cervical spine from tearing of the intervertebral disc at C6-C7 vertebral level. It occurs due to sudden fall of the head over occipital region.

What is linear skull fracture?

A linear skull fracture is a break in a cranial bone resembling a thin line, without splintering, depression, or distortion of bone.

What attaches to the sphenoid bone?

On the base of the sphenoid bone, several muscles attach to it’s legs, the medial and lateral pterygoid processes. As the name suggests, the pterygoid muscles, important for chewing and mastication, attach here.

What is behind the sphenoid bone?

Borders. The sphenoid bone has a common border with the frontal bone (via the sphenofrontal suture), the parietal bone (via the the sphenoparietal suture), the squamous part of the temporal bone (via the sphenosquamosal suture) and the occipital bone (via the spheno-occipital suture).

What does the sphenoid bone of the skull do?

Sphenoid bone has many essential functions. It helps form the base and lateral sides of the skull in combination with the orbital floor. Its many articulations with other bones give the skull rigidity. It is an attachment site for many of the muscles of mastication.

What is the difference between a bulging disc and a herniated disc?

“A bulging disc is like letting air out of a car tire. The disc sags and looks like it is bulging outward. With a herniated disc, the outer covering of the disc has a hole or tear. This causes the nucleus pulposus (jelly-like center of the disc) to leak into the spinal canal.”

Can herniated disc cause permanent nerve damage?

A severe case of a bulging disc can cut off nerve impulses, even causing permanent nerve damage. Additionally, you may experience sharp paints, incontinence, bowel movement irregularity, or even partial paralysis as the issue worsens.

What does the L4 L5 nerve control?

The L4 and L5 are the two lowest vertebrae of the lumbar spine. Together with the intervertebral disc, joints, nerves, and soft tissues, the L4-L5 spinal motion segment provides a variety of functions, including supporting the upper body and allowing trunk motion in multiple directions.

Where is disc L3 and L4?

The L3-L4 spinal motion segment, positioned in the middle of the lumbar spine, plays an important role in supporting the weight of the torso and protecting the cauda equina (nerves that descend from the spinal cord).

Where is your L2 and L3?

L2, L3, and L4 spinal nerves provide sensation to the front part of the thigh and inner side of the lower leg. These nerves also control movements of the hip and knee muscles.

What is spiral cord?

A column of nerve tissue that runs from the base of the skull down the center of the back. It is covered by three thin layers of protective tissue called membranes. The spinal cord and membranes are surrounded by the vertebrae (back bones).

Is a herniated disc a disability?

A severe herniated disc can be considered a disability and make you eligible for Social Security disability benefits if it meets the requirements in the Social Security Administration’s Blue Book. The Blue Book is the official listing of all of the conditions that qualify a person to receive disability benefits.

Which nerve is affected in disc herniation?

This pain is due to the herniated disc compressing the roots that make up the sciatic nerve, which then sends pain signals through the entire nerve, which extends from the lower back through the leg.

Can back problems cause neuropathy in feet?

Answer: Yes—in some severe cases, degenerative disc disease (DDD) can cause nerve problems in the feet. Degenerative disc disease, specifically of the lumbar spine, can actually cause nerve pain to radiate into the feet from your spine.
