House uses a cane to support his injured leg while walking in House, M.D.
The cane is one of the character’s most recognizable visual features. House developed chronic leg pain after an infarction in his quadriceps muscle, and the resulting disability affects his mobility throughout the series. He often leans on the cane while moving through the hospital or standing during consultations.
The prop also works as a character symbol. It signals House’s physical limitations while contrasting with his intellectual confidence and forceful personality. The cane is sometimes used dramatically or humorously, but it remains primarily a mobility aid connected to his leg injury.
Viewers may remember House using medication and other treatments for pain, but those are not substitutes for the device he carries. The specific support associated with his walking is a cane, not a crutch or walker.
