What is an intrinsic and extrinsic injury? - ANSWERSIntrinsic = infection, extrinsic=orthopedic What is the difference between an acute injury and a chronic injury? - ANSWERSAcute=macrotrauma, excessive force at a single bout, sudden onset Chronic=microtrauma, repeated over extended period of time, gradual onset What is a primary and secondary injury? - ANSWERSPrimary=direct immediate consequence, Secondary=accommodation to primary injury What is Dizzy Dean Syndrome? - ANSWERSAn example of secondary injury: While pitching for the NL in the in the 1937 All-Star Game, Dean was hit in the foot by a line drive. Told that his big toe was "fractured," Dean responded," Fractured, hell, the dam thing's broken!" Coming back too soon from the injury, Dean changed his pitching motion to avoid landing as hard on his sore toe, this altered his mechanics. As a result, Dean hurt his arm, losing his fastball. What are the 5 signs of inflammation? - ANSWERSHARPS - Heat, A loss of function, Red, Painful, Swelling What is the load? - ANSWERSStress - external/internal force acting on the tissue What is the deformation? - ANSWERSThe extent of the alteration to the tissue (distance) What does the extent of deformation depend on? - ANSWERSTissue composition, Speed of applied load, frequency of load, direction of loading What does the stress-strain curve describe? - ANSWERSThe amount of load a tissue can handle before it affects the mechanical capabilities and mechanical failure begins What is the yield point of the stress-strain curve? - ANSWERSLoad is greater than mechanical capabilities of the tissue. What are the forces that cause orthopedic injuries? - ANSWERSTension, Compression, Bending, Sheer, Torsion What are some injuries associated with tension? - ANSWERSankle sprain What are some injuries associated with compression? - ANSWERSBoxer's Fracture
