Also known as: Broken pelvis
Tom sustains an unstable pelvic fracture when a car crashes into his house. He requires emergent pelvic packing surgery due to hemorrhage and becomes critically unstable with cardiac arrest, requiring extensive resuscitation and intensive monitoring.
Also known as: Broken thigh bone
Tom has a right-upper-leg deformity from femoral fracture that requires reduction during his trauma surgery.
Also known as: V-fib
Tom goes into ventricular fibrillation multiple times during resuscitation, requiring defibrillation and ultimately third-degree heart block requiring further intervention.
Also known as: Brain bleed
Blair develops a 'walking and talking' classic extradural hematoma after the car crash. She appears fine initially but suddenly seizes with a blown pupil, leading to massive intracranial bleed, cardiac arrest, and death despite resuscitation efforts.
Also known as: NPH
Martin was misdiagnosed with Alzheimer's but actually has normal pressure hydrocephalus causing his dementia symptoms. The trauma from the car accident causes a CSF leak that temporarily relieves pressure and restores his memory and cognition. He ultimately refuses shunt surgery to maintain the lucid state because he cannot live with the knowledge that he killed someone.
Also known as: Internal bleeding
Martin has evidence of blood in his abdomen from the car accident requiring exploratory surgery to assess the extent of damage.
Also known as: Broken rib
Martin sustains multiple rib fractures from the car accident trauma.
Also known as: Postmortem C-section
After Blair dies from her intracranial bleed, the team performs an emergency perimortem cesarean section to deliver her baby while maintaining CPR to keep blood circulating. The baby boy is successfully delivered and survives.
Also known as: Mild traumatic brain injury
Maggie sustains a concussion when violently struck by the combative trauma patient Martin Davis. She initially lies about getting a CT scan but later admits to dizziness, revealing the concussion.
Also known as: Early-onset Alzheimer's
Referenced as part of Ellis Grey's medical history and discussed in context of genetic risk for Maggie Pierce. Richard Webber reveals to Maggie that Ellis had early-onset Alzheimer's that ended her career, which is relevant given Maggie's genetic predisposition.
