Head & Neck
Cranium – protects brain. Frontal Parietal (2) Occipital Temporal (2)
Facial Mandible Maxille (2) Zygomatic (2) Nasal
Cervical Vertebrae
Muscle Location Function
Sternocleidomastoid Anterior aspect of the neck
Flex neck; rotate the head
Trapezius Posterior aspect of the neck
Extends neck; adducts scapula
Brain Cerebrum – higher
thought processes Cerebellum – balance
and coordinated movement
Brainstem – vital body functions
Meninges- layers of tissue that surround brain and spinal cord. Has areas of space between each layer
DURA MATER- outer layer made up of arteries and veins
SUBDRUAL SPACE ARACHNOID LAYER- spider web of veins SUBARACHNOID SPACE- contains CSF PIA MATER- inner layer lines brain and spinal cord Cerebrospinal Fluid (CSF) - protects, cushions and
nourishes the central nervous system.
Intervertebral Disks Cartilagenous discs
that lie between the vertebrae.
Act as shock absorbers of the spine.
Cranial nerves 12 pair that branch
off of the brain
Spinal Nerves; nerve root pairs that branch off the spinal cord. Brachial Plexus (C5-T1) –
bundle of spinal nerves that innervate the shoulder and arm muscles
Concussions Characterized by immediate and
transient post-traumatic impairment of neural function
Mechanism of Injury Result of direct blow to the head
from either a fixed or moving object.
Signs of Injury Headache Loss of consciousness Tinnitus Nausea Irritability Confusion Disorientation Dizziness Amnesia Concentration difficulty Photophobia Sleep disturbances Vision disturbances Balance disturbances
Concussions Assessment:
Neuropsychological Testing If possible, preseason testing on a
computerized system (ImPACT). If a concussion occurs, retest injured athlete
following recommended protocols. Thorough evaluation of athlete: (Sport
Concussion Assessment Tool (SCAT 2 – see additional resources) is a tool that can be used to evaluate a concussed athlete.
Physical Examination – evaluation of athletes physical symptoms as listed previously.
Concussions Assessment
Balance/Coordination testing Balance Error Scoring System (BESS – see
additional resources) Romberg Test Finger to Nose
Treatment: Careful removal from
play Thorough physical
and neurological examination
Refer to physician for follow-up examination
Return to Play Guidelines: Depends on the level of play of the
athlete involved. Currently, the NCAA, UHSAA, and a new Utah State law regarding youth sports (HB 204) will dictate a specific plan for concussion management and return to play guidelines. It will include some variation of the following :
Progression through Return-To-Play stages on a case by case basis with final clearance by an approved, licensed health care professional:
Postconcussion Syndrome Persistent symptoms following concussion
- May begin immediately following injury and may last for weeks to months
Persistent headache Impaired memory Lack of concentration Anxiety Irritability Fatigue Depression Continued visual disturbances
Treatment – No clear guidelines Treat symptoms to greatest extent
possible Return athlete to play when all signs
and symptoms have fully resolved
Second Impact Syndrome Rapid swelling of the brain from
additional head trauma; life threatening
Second impact could be minor Could be caused by blow to
chest that accelerates head.
Signs and Symptoms No initial loss of consciousness Rapid worsening leading to:
LOC progressing to coma Dilated pupils Loss of eye movement Respiratory failure
Treatment: Immediate transport to medical facility
Prevention DO NOT LET THIS SITUATION
OCCUR! Careful decision making
regarding return to play following initial head trauma
