What is the name of House’s cane-associated leg injury in House M.D.?

House’s cane-associated leg injury in House M.D. is a quadriceps muscle infarction. The condition is a loss of blood supply to muscle tissue in his thigh, causing severe damage and chronic pain.

In the series’ backstory, House suffers the infarction after an aneurysm in his thigh becomes blocked. He delays treatment because he believes the muscle can recover, but the tissue damage becomes extensive. Surgeons eventually remove dead muscle, leaving him with a permanent limp and the need for a cane.

The injury explains several central features of House’s character: his chronic pain, his reliance on pain medication and his distrust of physicians who treated him. It is not simply a broken leg or a conventional orthopedic injury, which are common mistaken answers.

The show connects House’s physical disability to his professional identity. His pain contributes to his isolation and irritability, while his diagnostic skill allows him to notice medical details other doctors overlook. The storyline is fictionalized for drama, but muscle infarction is a real medical phenomenon.
