Causes can include stroke, multiple sclerosis, or spinal cord injury. Symptoms typically include muscle weakness, spasticity, increased reflexes, and loss of voluntary movement. ○ Whiplash/Cervical Sprain This injury usually occurs from a rapid back-and-forth movement of the neck, commonly from car accidents. It causes damage to the ligaments, muscles, and tendons in the cervical spine, leading to pain, stiffness, reduced range of motion, and headaches. ○ Stinger/Burner A stinger or burner is a common injury in contact sports, often caused by a sudden stretch or compression of the brachial plexus nerves. It results in a sharp, burning pain down one arm, along with numbness, tingling, and temporary weakness. ○ Thoracic Outlet Syndrome TOS is a group of disorders involving compression of nerves or blood vessels in the thoracic outlet, the space between the collarbone and first rib. Symptoms can include pain, numbness, and tingling in the neck, shoulder, arm, or hand. It often results from repetitive activity or poor posture. ○ Scheurmans Kyphosis This is a spinal disorder in which the vertebrae grow unevenly, causing an exaggerated forward curvature in the upper back. It is most common in adolescents and can cause back pain, stiffness, and reduced spinal flexibility. ○ Costocondral Separation/Injury This occurs when the cartilage connecting the ribs to the sternum (costochondral junction) separates or becomes damaged, often from trauma or sudden twisting. Symptoms include sharp chest pain, tenderness, and difficulty breathing deeply. ○ Tortocillis Torticollis is a condition where the neck muscles contract, causing the head to tilt to one side. It may result from muscle strain, injury, or congenital issues. Symptoms include limited neck mobility, pain, and visible tilting or twisting of the head. ○ Ruptured Spleen A ruptured spleen usually results from blunt abdominal trauma, leading to bleeding within the abdominal cavity. Symptoms include sharp left-upper-abdominal pain, shoulder pain, dizziness, and potentially life-threatening blood loss. Immediate medical intervention is critical. ○ Pneumothorax This is a condition where air enters the space between the lung and chest wall, causing lung collapse. It can occur due to trauma, certain medical conditions, or spontaneously. Symptoms include sudden chest pain, shortness of breath, and sometimes a rapid heart rate. ○ Hemothorax Hemothorax is the accumulation of blood in the pleural cavity around the lungs, typically due to chest trauma. Symptoms include chest pain, difficulty breathing, and signs of shock if blood loss is severe. It requires prompt medical treatment to drain the blood. ○ Kidney Contusion This is a bruise to the kidney, usually caused by a direct blow to the back or flank. Symptoms can include flank pain, bruising, hematuria (blood in urine), and potentially nausea or vomiting. Mild cases may heal with rest, while severe cases may need more intensive care. ○ Commotio Cordis Commotio cordis is a rare but serious condition where a blow to the chest disrupts the heart’s rhythm, potentially leading to sudden cardiac arrest. It usually occurs in young athletes during sports with high-speed projectiles, and immediate CPR or defibrillation is essential. ○ Liver Contusion A liver contusion is a bruise on the liver, often resulting from blunt abdominal trauma. Symptoms may include right-upper-abdominal pain, tenderness, and nausea. Severe contusions can lead to internal bleeding, requiring close monitoring and possibly surgical intervention.
