EDUCATIONAL OBJECTIVES
The learner should, at the completion of the chapter, be able to perform the following:
Thoracic and abdominal injuries are less common than extremity injuries. However, these injuries can be life threatening. In order to provide appropriate care, these injuries demand immediate evaluation and subsequent activation of the emergency medical system (EMS).
This chapter outlines general evaluation procedures used to assess thoracic and abdomen injuries. A slight deviation from the H.O.P.S. injury evaluation format is presented in this chapter. Specifically, the evaluation of thorax and abdomen must follow this precise assessment process: primary and secondary survey. Anatomical components of the thorax and abdomen, their function, specific conditions involving them, and the signs and symptoms usually revealed through evaluation are also presented. Common principles are shared and tests are demonstrated that can aid you, as an examiner, to better assess both acute trauma and non-traumatic conditions.
When thoracic injury is suspected, begin your evaluation with the primary survey. The primary survey assesses:
Once your primary survey is completed and you determine the athlete's condition is non life-threatening, perform a secondary survey. The SECONDARY SURVEY consists of two elements.
Following determination of the vital signs, the Physical Examination then progresses to:
The performance of Palpation and Special Tests assists the health care professional in determining which specific anatomical structures have been injured and what appropriate medical treatment is needed. Palpation determines: general and specific areas of tenderness; location of deformities; location and extent of swelling; air crepitus (produced by air caught in subcutaneous tissue); bony crepitus (produced by the rough edges of fractured bones rubbing together); asymmetry; muscle rigidity; and abdominal rebound tenderness. Special tests aid in: evaluating active range of motion; resistance to movement in the different planes to elicit painful ranges and musculoskeletal weaknesses; evaluation of pain and dysfunction associated with inspiration and expiration; and passive stress on bony structures to assess possible fractures/separations. This area of the body is innervated by a number of different nerves. The sensory distribution of a nerve root is called a dermatome, which produces feeling in a certain anatomical area. The motor distribution of a group of muscles innervated by a single nerve root is called a mytome and it produces movement in anatomical structures.
The abdominal cavity is divided into these four quadrants: Right Upper Quadrant, Left Upper Quadrant, Right Lower Quadrant, and Left Lower Quadrant. When examining the abdomen, each quadrant should be auscultated, percussed, and palpated.
One of the most important functions of palpation is to determine signs and symptoms of an acute abdomen. These symptoms may be present due to the leakage of blood, puss, or bowel contents into the abdominal cavity causing peritoneal irritation.
Signs of an acute abdomen
Rebound TendernessRebound tenderness is identified by the examiner pressing deeply into the abdominal cavity and then quickly releasing, allowing the abdominal wall to rebound back to its original position. If this procedure is painful, peritoneal irritation may be present. Rigidity of the abdominal wall muscles occurs when peritoneal irritation causes reflex spasm of the abdominal muscles, producing a board-like hardness, thus preventing the examiner from performing deep palpation. Guarding occurs when the patient voluntarily tries to prevent the examiner from palpating the abdomen.
Rigidity
Guarding
The Valsalva Maneuver is used to provoke an increase in pain or mass protrusion if significant intra-abdominal trauma has occurred.To perform the Valsalva Maneuver, have the athlete take a deep breath, hold their breath, and strain as if having a bowel movement. Any worsening of pain or mass protrusion through the abdominal wall is considered a positive test.
When evaluating Range of Motion, your assessment is divided into active, passive, and resistive motions and may be approached from the three anatomical planes of motion:
The Sagittal Plane motion assesses range of motion limitations and associated findings in the sagittal plane. To evaluate, the athlete stands and slowly flexes the trunk to the point where the hands touch the toes or the floor. Ask the athlete to slowly return from full trunk flexion to trunk extension.
The Frontal Plane motion assesses range of motion limitations and associated findings in the frontal plane. To evaluate, the athlete should stand, and than slowly, laterally flex the trunk to the right as far as possible. Then the athlete laterally flexes the trunk through the neutral standing position to the far left.
The Transverse Plane motion assesses range of motion limitations and associated findings in the transverse plane. To evaluate, the athlete stands and slowly rotates the trunk to the right as far as possible. This position is held and then slowly rotated to the extreme left.
The Inspiration and Expiration Tests assess inspiratory and expiratory function and elicit signs and symptoms of thoracic injury. Evaluate Inspiration and Expiration by having the athlete breathe in as much air as possible and hold for a few seconds. Then, ask the athlete to breathe out slowly and fully in an attempt to expire all air from the lungs. Instruct the athlete to hold the maximally expired position for a few seconds. During these breathing activities, observe any patient apprehension or limitations in the inspiratory movement as well as any display of associated pain. Question the patient regarding location and nature of any symptoms elicited by these procedures. Some specific signs or symptoms are:
These chest compression tests can help distinguish between muscle contusions/strains and loss of bony stability and integrity. The chest compression testing may be accomplished in the standing or sitting position. However, if the athlete is having complications, the supine and sidelying position may allow for better patient comfort and relaxation.
Anterior/Posterior Chest Compression Test assesses lateral rib cage bony integrity. To perform the anterior/posterior compression test, instruct the athlete to either sit or stand. You should place the palmar surface of one hand anteriorly on the chest wall at the level of the affected area. Place your other hand at the corresponding level posteriorly. Compress the rib cage by pushing your hands toward each other. This inward pressure anteriorly and posteriorly will cause the rib cage to bow outward laterally which will elicit pain and bony crepitis if the injury to the lateral rib cage is a fracture. However, if the injury is a contusion or muscle spasm, no pain or crepitis will be elicited.
The Lateral Chest Compression Test assesses anterior or posterior rib cage bony integrity. To perform the lateral compression test, instruct the patient to either sit or stand. Then, as the examiner, place the palmar surface of your hands laterally on the athlete's chest wall sides at the affected area level. Compress the rib cage by pushing your hands toward each other. This inward pressure from both sides will cause the rib cage to bow outward anteriorly and posteriorly. This inward pressure laterally will cause the rib cage to bow outward which will elicit pain and bony crepitis if the injury to the anterior/posterior lateral rib cage is a fracture. However, if the injury is a contusion or muscle spasm, no pain or crepitis will be elicited.

ASSESSMENT TESTS
All injured anatomical structures should be properly evaluated. The purpose of a thorough evaluation is to enable the allied health professional to properly assess the severity of the injury and to make recommendations regarding medical treatment and possible return to participation. Listed below is a review of evaluation techniques utilized by physician and certified athletic trainer.
Tests for Bony Integrity
Palpation: physical inspection
Compression: inward force applied to thorax and ribs through inspiration
and manual pressure.
Distraction: outward force applied to thorax and ribs through expiration.
Compression Tests: Thorax/Ribs
Anterior/Posterior and Lateral: compression force applied to thorax and ribs through manual pressure.
Compression Tests: Pelvis
Anterior/Posterior and Medial/Lateral: compression force applied to pelvis through manual pressure.
Breathing
Inspiration: action of taking a breath (inhaling)
Expiration: action of releasing a breath (exhaling)
Range of Motion: Torso
Flexion: moving the torso forward in the sagittal plane, the athlete
stands and slowly flexes the trunk to the point where the hands touch the
toes or the floor.
Extension: moving the torso backward in the sagittal plane, the athlete
stands and slowly flexes the trunk to the point where the hands touch the
toes or the floor. Lateral Flexion: moving the torso laterally in the frontal
plane, the athlete should stand and slowly, laterally flex the trunk to
the right as far as possible. Then, the athlete laterally flexes the trunk
through the neutral standing position to the far left.
Rotation: rotating the torso in the transverse plane, the athlete stands
and slowly rotates the trunk to the right as far as possible, then slowly
rotates to the extreme left.
Signs of Acute Abdomen
Rebound Tenderness: pain in the abdomen upon the release of pressure
from the abdomen.
Rigidity: upon palpation, abdomen is rigid or hard and not fully palpable.
Guarding: patient contracts muscles while palpating so that the palpation
does not hurt.
Tests to Detect Possible Peritoneal Irritation (intra-abdominal pressure)
Iliopsoas Test: moving leg into hip flexion, which causes abdomen pain.
Obturator Test: with hip and knee in 90 degree flexion, internal and
external rotation of hip will cause abdomen pain.
Heel Pound Test: with hip and knee in full extension, tap heel to increase
pain in abdomen
Valsalva Maneuver: athlete take a deep breath, hold their breath, and
strain as if having a bowel movement.
IMMEDIATE REFERRAL IS NECESSARY IF THE FOLLOWING SIGNS AND SYMPTOMS ARE PRESENT IN A THORACIC AND/OR ABDOMINAL ASSESSMENT.
Acute traumatic injuries occurring to the thorax may involve the heart, lungs, and rib cage. Remember, evaluation of such injuries require current First Aid and C.P.R. certification. As an allied health professional, it is essential that you are trained in current basic life support techniques.
The Heart is located in the center of the thoracic cavity and positioned slightly to the left. The heart pumps oxygenated blood from the heart to the body and de-oxygenated blood from itself to the lungs. One of the more common conditions involving the heart is a myocardial infarction, commonly referred to as a heart attack. Myocardial Infarctionis ischemia (decrease in oxygenated blood flow) to cardiac tissue which may result in a disturbance of normal heart function characterized by arrhythmia.
Signs and Symptoms of Myocardial Infarction:
The Lungs, located in the thoracic cavity and protected by the rib cage, are formed by a network of branching tubes and air sacs. This network provides respiration whereby the blood from the body is re-oxygenated. A Pneumothorax occurs either spontaneously or traumatically from blunt or sharp trauma to the chest wall. Pneumothorax is characterized by air accumulation in the pleural space. The air escapes from the lung upon each inspiration, collects in the pleural space and eventually results in lung collapse. Spontaneous, traumatic, and tension pneumothorax signs and symptoms should be explored with your patient. Another serious lung condition, Hemothorax, results when blood accumulates in the pleural space.
Thoracic related bony and joint injuries can occur to the rib cage structure. The Rib Cage outlines the thoracic borders and provides protection to the heart, lungs, great vessels (aorta and vena cava), liver, and spleen. Its ability to expand and relax is essential in assisting the lungs' respiratory function. Other than contusions and strains, rib fractures are the most common injuries seen in the thoracic area. Nondisplaced fractures are usually benign; however, displaced fractures may result in lacerations to the lung and associated intercostal vessels. You should remember the following about rib fractures:
non-displaced are the most common; displaced rib fractures may result in laceration of the lung or an associated intercostal vessel; injuries usually involve the 5th to 9th ribs; tremendous forces are necessary to fracture the 1st and 2nd ribs; and fracture of the 7th through 12th ribs may be associated with liver, spleen, or kidney injuries.
The signs and symptoms of rib fractures are:
Bronchitis: inflammation of the bronchial tubes. Bronchitis is usually characterized by a progressive cough.
Hemoptysis: expectoration of blood arising from the lungs (patient's coughing up blood or blood-stained sputum).
Hyperventilation: increase in respiratory rate usually associated with anxiety which causes a change in the acid-base balance of the blood. Symptoms include dyspnea and numbness and tingling in the hands, fingers, and around the mouth.
Influenza: a viral illness characterized as an acute onset of fatigue, muscle ache, headache, and fever; usually lasts one to two weeks.
Pleuritic chest wall pain: inflammation of the serous membrane lining, which lies between the lung and chest wall, causing pain with inspiration and expiration or cough.
Pneumonia: inflammation of the lungs caused primarily by bacteria, viruses, chemical irritants, vegetable dusts, and allergy. Usual symptoms are fever, cough, and chest pain.
The abdominal cavity is divided into these four quadrants: Right Upper Quadrant, Left Upper Quadrant, Right Lower Quadrant, and Left Lower Quadrant. When examining the abdomen, each quadrant should be auscultated, percussed, and palpated. One of the most important functions of palpation is to determine signs and symptoms of an acute abdomen which are rebound tenderness, rigidity, and guarding. Additionally, a positive valsalva manuever could indicate significant intra-abdominal trauma has occurred.
The Spleen is the body's largest lymphatic organ and is located in the left upper quadrant, directly below the diaphragm and behind the 9th, 10th, and 11th ribs. It serves as a reservoir of red blood cells and regulates the number of red blood cells in circulation. The spleen also destroys old or defective red blood cells and produces white blood cells. Signs and symptoms of spleen injury are:
Appendicitis--Inflammation of the appendix. Generally affects the young and is more common in males. Appendicitis is characterized by high fever, signs of acute abdominal pain often localized in the right lower quadrant, nausea, vomiting, and anorexia.
Indigestion (heartburn)--Incomplete or imperfect digestion, usually accompanied by one or more of the following symptoms: pain, nausea, vomiting.
Stitch in the side (sideache)--Sharp pain in the side usually associated with strenuous physical activity, usually caused by muscle spasm and/or trapped gas.
