What does C7 and C8 control?
The C6 and C7 cervical vertebrae (and the C8 spinal nerve) form the lowest levels of the cervical spine and directly impact the arm and hand muscles.
What can someone with a C7 spinal cord injury do?
C7 injury. Nerves control elbow extension and some finger extension. Most can straighten their arm and have normal movement of their shoulders.
What nerves do C7 C8 affect?
C7 helps control the triceps (the large muscle on the back of the arm that straightens the elbow) and wrist extensor muscles. The C7 dermatome goes down the back of the arm and into the middle finger. C8 helps control the hands, such as finger flexion (handgrip).
What part of the body does C7 affect?
The C7 myotome is a group of muscles controlled by the C7 nerve. These muscles include those involved in straightening the elbow, lifting the wrist, elongating the fingers to an outstretched hand, and the triceps muscle in the upper arm.
How is C8 radiculopathy treated?
Nonsurgical treatments for cervical radiculopathy typically include one or more of the following:
- Rest or activity modification.
- Physical therapy.
- Ice and/or heat therapy.
- Medications.
- Cervical epidural steroid injection.
- Manual manipulation.
- Cervical traction.
Can you walk after a C7 spinal cord injury?
Mobility. With a C7 spinal cord injury, you should be able to start operating a manual wheelchair. While a power wheelchair may be easier to use and get around with, it won’t help strengthen your arm muscles, and likely won’t be covered by insurance for someone with a C7 injury.
Can you walk after a C7 fracture?
Depending on the severity of a spinal cord injury, patients may find themselves unable to walk. In situations like these, patients work with a variety of medical professionals to regain the ability to walk, so they can return to as much normal bodily function as possible.
Does C7 fracture cause paralysis?
A C7 spinal cord injury may result in quadriplegia, which describes paralysis in the arms, legs, and sometimes, the trunk. However, because the C7 segment is further down the cervical region of the spinal cord, the majority of your arm functions may be spared.
Can C7 cause chest pain?
Cervical angina is one potential cause of noncardiac chest pain and originates from disorders of the cervical spine. Although the exact incidence is unknown, in 1 series of 241 patients with C7 radiculopathy undergoing anterior cervical diskectomy, 16\% of the patients had associated chest pain or subscapular pain.
What causes C8 radiculopathy?
The most common causes of cervical radiculopathy are when a nerve root becomes inflamed or damaged due to a nearby bone spur or cervical herniated disc, such as from spinal degeneration over time or an injury. Many other less common causes of cervical radiculopathy are possible, such as infection or tumor.
What muscles are innervated by C8?
These muslces are: Latissimus dorsi, Pectoralis major, Triceps, Palmaris longus, Flexor digitorum superficialis, Flexor policis longus, abductor policis longus, Extensor policis brevis, Extensor policis longus, Extensor carpi ulnaris, Flexor carpi ulnaris, Flexor digitorum profundus, Lumbricals, and Interossei.
What is the best spinal cord injury treatment?
Stabilization. Before SCI patients can try any of these potential treatments,stabilization of the spinal cord is crucial.
How do you cure spinal cord injury?
After acute spinal cord injuries occur, physical therapy, occupational therapy, and other rehabilitation interventions sometimes are required. There is no cure for spinal cord injury; however, researchers continue to work on advances, many of which have resulted in a decrease in damage at the time of the injury.
What are the signs of a spinal cord injury?
Pain and numbness,or burning sensation
What are the common causes of spinal cord injuries?
Your brain and central nervous system. The central nervous system consists of the brain and spinal cord.
