An infarction is central to Gregory House’s chronic leg pain in House, M.D.
House suffers an infarction in the quadriceps muscle of his right thigh before the series begins. The loss of blood supply damages the muscle and leaves him with permanent pain and impaired movement. He consequently walks with a cane and develops a dependence on opioid pain medication.
The injury is connected to a misdiagnosed vascular problem. House eventually has the dead muscle removed, but the procedure cannot restore normal function or eliminate the continuing pain. This history explains both his limp and his repeated concern with pain management.
The condition is sometimes described casually as a blood clot or a leg injury, but those descriptions are incomplete. An infarction means tissue death caused by inadequate blood supply. In House’s case, the event affects muscle rather than being presented simply as a broken bone or ordinary traumatic injury.
