Anatomy Review Skull The skull has 8 cranial bones & 14 facial bones. have articulations called suture joints.

Anatomy Review (continued) Soft tissue structures protect the cranium.

Anatomy Review (continued) The _________ Located underneath cranial bones, consisting the dura, arachnoid, and pia mater.

Anatomy Review (continued) _______________________ (CNS) Brain and ___________ comprise the CNS. CNS is protected by meninges, cranium, and vertebrae. CNS consists of gray and white matter and weighs 3.0 to 3.5 lbs (adult). Brain has three basic components, the cerebrum, ______________, and brain stem. Neural impulses travel via ____ pairs of cranial nerves and 31 pairs of spinal nerves.

Anatomy Review (continued) The Neck (cervical spine) The __ cervical vertebrae provide support for the head and protection for the spinal cord.

Anatomy Review (continued) The first cervical vertebra (C-1) is called _____ Atlas articulates with the occipital bone The second cervical vertebra (C-2) is called _____

Head Injuries in Sports Even minor head trauma can result in serious injury. Brain tissue is unable to repair itself; any tissue loss results in some level of ___________ disability. Severe injuries can result in _________ Coaches can learn to recognize head injuries and render first aid when necessary.

Mechanisms of Head Injury Direct injury to the head involves a blow to the head that causes injury at impact site. _________________ injury Coup injury Indirect injury to the head results from damaging forces traveling to the head from other parts of the body. Treat every head injury as if there is a neck injury and vice versa.

Head Injuries in Sports Cranial injury: Involves the bones of the skull. May be associated soft tissue injury. _________________ skull fracture: Involves bone fragments being pushed into the cranial region.

Head Injuries in Sports (continued) _______________ is “a clinical syndrome characterized by immediate and transient impairment of neurologic function secondary to mechanical forces.”

Concussion signs and symptoms ____________ Nausea Balance problems Double or fuzzy __________ Sensitivity to light or noise Sluggishness Felling ____________ Concentration and memory problems Symptoms may worsen with exertion Athlete should not return to play until __________________!

Head Injuries in Sports (continued) _____________ Amnesia: forgets events prior to hit _____________ Amnesia: forgets events after hit.

Head Injuries in Sports (continued) _________________ Syndrome (SIS) can be a serious problem! Results when an athlete with a head injury receives another head injury before the symptoms of the first injury have resolved. Involves rapid and catastrophic brain swelling. SIS can result in __________. Any athlete sustaining a head injury, no matter how minor, should be monitored by a physician before being cleared to return to participation.

Initial Survey Always assume a neck injury has also occurred. If unconscious, attempt to arouse and note approx. time of injury. Immobilize head and neck immediately; do not remove athlete’s helmet!! (Stabilizing the athlete’s head and neck)

Initial Survey (continued) If unconscious, detect ______________by: Listening near the athlete’s face for typical breathing sounds. Looking for movements of the thorax and/or abdomen. If no signs of circulation are present, begin __________ and summon EMS.

Physical Examination The physical exam must include assessments of: ________________________ or unconsciousness. Extremity strength without moving the neck, if conscious. Mental function, if conscious. Signs and movements. Neck _________

Physical Exam (continued) If head injury is suspected: ________ remove helmet. Don’t move. ___________ arouse someone with ammonia capsules. If athlete is conscious, use quick neurological tests, such as grip strength and skin sensation. Examine the eyes, noting ______________, responsiveness to light, and side-to-side movement. Palpate the neck for deformity.

Special Tests Neurologic exam Eye function Assess cerebral testing, __________________ testing, cerebellar testing, sensory and reflex testing Eye function Pupils equal round and reactive to light (__________) Dilated or irregular pupils Ability of pupils to accommodate to light variance Eye tracking - smooth or unstable (_____________, which may indicate cerebral involvement) Blurred vision

Balance Tests Coordination tests __________________ Assess static balance - determine individual’s ability to stand and remain motionless Tandem stance is ideal Coordination tests Finger to nose, heel-to-toe walking Inability to perform tests may indicate injury to the cerebellum

________________________- Used to establish impact of head trauma on cognitive function and to obtain objective measures to assess patient status and improvement On or off-field assessment Months in reverse order, counting backwards Tests of recent memory (score of contest, breakfast game, _______________ http://sports.espn.go.com/broadband/video/videopage?videoId=3094263

Cervical Spine Injuries Neck Injuries Majority occur in football, rugby, ice hockey, soccer, _________-, and gymnastics. Cervical injuries, however, can occur in almost any sport. ________________ injuries are rare--less than 2 in 100,000 of all neck injuries reported in the United States.

Cervical Spine Conditions Mechanisms of Injury

Cervical Spine Injuries (continued) Mechanisms include hyperflexion, hyperextension, rotation, lateral flexion, and _________________. Neck strains rarely involve neurologic damage. Serious injuries occur when intact vertebra or fragments of fractured vertebra are displaced or an intervertebral disk ruptures and places pressure on spinal cord or nerve roots.

Mechanism of Cervical Spine Injuries ___________ produces most cervical spine injuries. 1976 NCAA enacted the rule barring “spearing.” Any forced movement of cervical spine can result in injury. Brachial plexus injuries can produce significant, but transient symptoms. Coaching personnel must take great care when conducting an examination of an athlete suspected of having a neck injury.
