The right ventricle is most susceptible to injury due to its prominent location. The two primary consequences of traumatic injury to the heart are severe hemorrhaging and fluid buildup around the heart. Musculoskeletal
Musculoskeletal injuries affect the skeleton and the muscular system. Soft tissue injuries affect the skeletal muscles, ligaments, and tendons. Ligament and tendon injuries account for half of all musculoskeletal injuries. Ligament sprains and tendon strains are common injuries that do not require intervention, but the healing process is slow. Physical therapy can be used to assist reconstruction and use of injured ligaments and tendons. Torn ligaments or tendons typically require surgery. Skeletal muscles are abundant in the body and commonly injured when engaging in athletic activity. Muscle injuries trigger an inflammatory response to facilitate healing. Blunt trauma to the muscles can cause contusions and hematomas. Excessive tensile strength can overstretch a muscle, causing a strain. Strains may present with torn muscle fibers, hemorrhaging, or fluid in the muscles. Severe muscle injuries in which a tear extends across the muscle can cause total loss of function. Penetrative trauma can cause laceration to muscles, which may take an extended time to heal. Unlike contusions and strains, lacerations are uncommon in sports injuries.Traumatic injury may cause various bone fractures depending on the amount of force, direction of the force, and width of the area affected. Pathologic fractures occur when a previous condition weakens the bone until it can be easily fractured.
Limb
Inadequate blood supply to a limb may results in acute limb ischemia or chronic limb threatening ischemia. Cutaneous
Reduced blood flow to the skin layers may result in mottling or uneven, patchy discoloration of the skin. Kidney Ischemia
Kidney Ischemia is a loss of blood flow to the kidney cells. Several physical symptoms include shrinkage of one or both kidneys, renovascular hypertension, acute renal failure, progressive azotemia, and acute pulmonary edema. It is a disease with high mortality rate and high morbidity. Failure to treat could cause chronic kidney disease and a need for renal surgery. Causes
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia. An aneurysm is one of the most frequent causes of acute arterial ischemia. Other causes are heart conditions including myocardial infarction, mitral valve disease, chronic atrial fibrillation, cardiomyopathies, and prosthesis, in all of which thrombi are prone to develop. Occlusion
The thrombi may dislodge and may travel anywhere in the circulatory system, where they may lead to pulmonary embolus, an acute arterial occlusion causing the oxygen and blood supply distal to the embolus to decrease suddenly. The degree and extent of symptoms depend on the size and location of the obstruction, the occurrence of clot fragmentation with embolism to smaller vessels, and the degree of peripheral arterial disease (PAD).
