Top 10 Motor - Vehicle Accident Causes

  1. 1.Brachial Plexopathy

    The brachial plexus is a complex nerve network located in the upper chest deep to the collar bone, which supplies the shoulder, arm, forearm, and hand. Damage to the brachial plexus is usually due to mechanical injury or trauma, and can interfere with normal nerve function causing numbness, pain, and/or weakness.

    You should visit your primary care physician to discuss these symptoms. It is likely the doctor will perform a thorough physical exam, and in many cases refer you to a specialist, physical therapist, or both. A professional evaluation is very important, as surgical treatment might be required for a brachial plexus nerve injury.

    Rarity:
    Common
    Top Symptoms:
    pain in one arm, shoulder pain that shoots to the arm, arm weakness, numbness in one arm, shoulder pain
    Urgency:
    Primary care doctor
  2. 2.Concussion Not Needing Imaging

    A traumatic brain injury (TBI), or concussion, happens when a bump, blow, jolt, or other head injury causes damage to the brain. Every year, millions of people in the U.S. suffer brain injuries. More than half are bad enough that people must go to the hospital, and the worst injuries can lead to permanent brain damage or death.

    You do not need to seek immediate medical care. Make sure your symptoms do not change. If they do, go immediately to the ER. If not, follow-up with the doctor in the coming days.

    Rarity:
    Common
    Top Symptoms:
    dizziness, irritability, difficulty concentrating, depressed mood, trouble sleeping
    Symptoms that always occur with concussion not needing imaging:
    head or face injury
    Symptoms that never occur with concussion not needing imaging:
    recent fall from 6 feet or higher, severe vomiting, posttraumatic amnesia over 30 minutes, slurred speech, fainting, moderate vomiting
    Urgency:
    Primary care doctor
  3. 3.Traumatic Vertebral Fracture

    Vertebral fracture is a fracture or dislocation of a vertebra that can cause bone fragments to pinch and damage the spinal nerves or spinal cord. Most spinal fractures occur from car accidents, falls, gunshot, or sports.

    Call 911 immediately.

    Rarity:
    Common
    Top Symptoms:
    back pain, constant back pain, severe back pain, back pain that shoots down the leg, back pain affecting the spine
    Symptoms that always occur with traumatic vertebral fracture:
    back pain
    Symptoms that never occur with traumatic vertebral fracture:
    mild back pain
    Urgency:
    Emergency medical service
  4. 4.Traumatic Brain Injury

    Traumatic brain injury (TBI) happens when a bump, blow, jolt, or other head injury causes damage to the brain.

    You should go to the hospital immediately. More than half of Traumatic Brain Injuries are bad enough that people must go to the hospital. The worst injuries can lead to permanent brain damage or death. There, doctors will examine you and take images of your brain to see if there's any bleeding.

    Rarity:
    Common
    Top Symptoms:
    new headache, irritability, clear runny nose, vision changes, general numbness
    Symptoms that always occur with traumatic brain injury:
    head injury
    Urgency:
    Emergency medical service
  5. 5.Concussion (Mild Traumatic Brain Injury) Needing Imaging

    Mild traumatic brain injury requiring imaging is defined as being fairly responsive after an injury to the head but with enough warning signs that a picture of the inside of the skull needs to be taken.

    You should go to the emergency room as soon as possible (within the next hour). The risk factors and symptoms around your injury make it possible that something serious is developing within your skull, and thus, a picture needs to be taken.

    Rarity:
    Common
    Top Symptoms:
    nausea or vomiting, dizziness, sensitivity to light, difficulty concentrating, frequent mood swings
    Symptoms that always occur with concussion (mild traumatic brain injury) needing imaging:
    head or face injury
    Urgency:
    Hospital emergency room

  6. 6.A Shoulder Strain

    Shoulder strain, also known as a muscle pull, is a common occurrence attributed to a damaged muscle and often is the result of heavy lifting or sports.

    You can safely treat this condition on your own with anti-inflammatory drugs, physical therapy, heat or cold therapy, and other conservative treatment approaches. In most instances, non-surgical treatment is the first approach, and many people can avoid surgery altogether. Persistent pain after conservative treatment may respond to corticosteroid injections but may eventually require surgery.

    Rarity:
    Uncommon
    Top Symptoms:
    pain in one shoulder, pain in the front of the shoulder, shoulder pain from overuse, shoulder pain from an injury, sports injury
    Symptoms that always occur with a shoulder strain:
    pain in one shoulder
    Symptoms that never occur with a shoulder strain:
    arm weakness, arm numbness
    Urgency:
    Phone call or in-person visit
  7. 7.Acl Injury

    The ACL (anterior cruciate ligament) is a super-important tendon that connects the femur (thigh bone) to the tibia (shin), keeping the tibia from flying forward every time a step is taken. Tearing happens in a lot of accidents and sports, unfortunately.

    You should seek immediate medical care at an ER. An ACL tear is very painful and requires surgery, and the sooner that happens, the better the outcome.

    Rarity:
    Rare
    Top Symptoms:
    knee pain, pain in one knee, knee instability, knee pain from an injury, swollen knee
    Symptoms that always occur with acl injury:
    knee pain
    Symptoms that never occur with acl injury:
    mild knee pain
    Urgency:
    Hospital emergency room
  8. 8.Femoral Shaft Fracture

    A femoral shaft fracture is a break anywhere along the long, straight part of the femur (thighbone) known as the shaft. Since the femur is the longest, strongest bone in the body, it is fairly difficult to break it (car crashes account for the most femur fractures).

    You are likely feeling extreme, severe pain in the impacted leg and should go directly to the emergency room via ambulance. From that point, your doctor will determine how to proceed (usually, surgery is needed followed by a long recovery period).

    Rarity:
    Rare
    Top Symptoms:
    abnormally high heartrate, constant upper leg pain, thigh pain, severe thigh pain, swollen thigh
    Symptoms that always occur with femoral shaft fracture:
    inability to bear weight immediately after injury, thigh pain, severe thigh pain, pain when touching the thigh, swollen thigh, constant upper leg pain
    Urgency:
    Emergency medical service
  9. 9.Thigh Nerve Issue (Meralgia Paresthetica)

    Meralgia paresthetica is a nerve condition that causes an area of skin over the upper outer thigh to feel numb, tingly, or painful. This is caused by compression of a nerve known as the lateral cutaneous nerve of the thigh as it passes underneath a tough fibrous ligament known as the inguinal ligament.

    You should visit your primary care physician to confirm the diagnosis and discuss treatment options. Generally, this condition is treated with rest, physical therapy, pain medication, and occasionally corticosteroid injections.

    Rarity:
    Rare
    Top Symptoms:
    hip pain, pain in one thigh, pain in one hip, pain in the outside of the hip, thigh numbness
    Symptoms that never occur with thigh nerve issue (meralgia paresthetica):
    new headache, swollen hip, swollen hips, swelling of one hip, leg swelling, weakness of both legs, leg weakness
    Urgency:
    Primary care doctor
  10. 10.Eye - Socket (Orbital) Fracture

    The middle part of the face or around the eye is fragile. A strong force hitting the area can cause a fracture, which can often hurt the surrounding soft tissue, making it an emergency to diagnose and treat.

    You should go to the ER immediately by car. There, a careful exam by the doctor and imaging (typically CT) can confirm the diagnosis. Treatment involves setting the fractured area to avoid further injury. You will possibly need surgery and antibiotics. You should NOT blow your nose, which would possibly worsen the injury.

    Rarity:
    Rare
    Top Symptoms:
    eye pain from an injury, recent eye injury, swelling of the eye area, bruised eye, eye numbness
    Symptoms that always occur with eye-socket (orbital) fracture:
    eye pain from an injury, recent eye injury
    Urgency:
    Hospital emergency room
