﻿In this video, we’ll be taking a look at cervical injuries in American football players.
While most injuries are related to pulling and stretching of the muscles, tendons, and
ligaments of the neck, there are more significant injuries besides these sprains and strains.
The most common cause of cervical injury for American football athletes
are burners and stingers, which occur when nerves from the neck into the shoulder are injured upon
impact. These injuries are appropriately named after the characteristic stinging or burning
pain that radiates down the shoulder. Fortunately, most cases of burners and stingers are temporary.
Nerves are the link between your brain and your muscles. There is a network of
nerves traveling through the shoulder and into the arm called the brachial plexus.
These nerves originate out of the spinal canal at the neck.
A direct blow to the lateral shoulder pad that forces the shoulder into a depressed position
and the neck in the opposite direction results in hyperextension of the neck. This overstretching
pinches the nerves in the brachial plexus and causes a downstream effect on the arm. With time,
rest, and gentle stretching, most of these injuries recover.
A more serious cervical injury is a cervical fracture,
most commonly referred to as a broken neck. But even with a broken neck,
most players make a full recovery as long as the nerves are not permanently affected.
In the more common scenario, the patient has a broken neck bone,
but an intact spinal cord. The vertebral fracture and associated dislocation
can be treated with or without surgery depending on the severity of the injury.
In the more serious scenario, the patient has a broken neck, and an incomplete or
partial spinal cord injury. The chance of recovery is dependent on two factors:
the site of injury and the severity of the damage to the spinal cord. For example,
central cord syndrome -- in which the central region of the spinal cord is damaged due to a
hyperextension injury -- is characterized by weakness in the arms. It has a good prognosis
with many patients regaining arm strength, with good improvement in the first six weeks.
In the most significant scenario, the patient has a broken neck and a complete spinal cord
injury. If the damage is severe, the patient will be completely paralyzed below the neck. The C4-C5
is the level where the nerves regulate the muscle contraction and relaxation of the diaphragm,
the main muscle involved in breathing. An injury at or above the level of C4
will impact the patient’s breathing. This is, unfortunately, a life-threatening condition.
That being said, most cervical fractures without significant instability can be
treated without surgery and can be placed in a hard collar immobilization for a period of 6
to 12 weeks. Fusion surgery is recommended for unstable fractures
and players are generally allowed to return to play if there is no pain, full range of motion,
normal muscle strength, complete fusion on imaging, and a normal neurological exam.
In the last video, we took a look at sports-related injuries in children
and young adolescents with young teenagers most at risk for suffering cervical injuries.

Deciding how and when athletes are allowed to return to play
is highly dependent on the recommendation of the surgeon and pattern of injury. Because
American football athletes are at high risk for cervical spine injury and re-injury,
the recovery process and evaluation are important in determining whether players are fit to return
to play without risk of serious., permanent injury. There is no one-size-fits-all strategy
when it comes to deciding when players are fit to return to play. Injuries are
highly individual and return to play decisions need to be assessed on a case-by-case basis.
Football is America’s most popular sport but has associated risks. Football athletes
must be provided the proper treatment and care to promote recovery and minimize their
risk of re-injury before returning to the field. Until next time, this is Dr. Shim.
