Dr. House’s famous walking aid in House M.D. is a cane.
House uses a cane because of chronic pain and impaired movement in his right leg. The injury resulted from an infarction in his quadriceps muscle, a backstory that explains both his limp and his dependence on pain medication.
The cane is more than a prop: it is a recurring visual symbol of House’s physical limitations and his refusal to present himself as conventionally reassuring. His distinctive gait and cane also make him immediately recognizable in the hospital.
House sometimes changes how he uses the cane, and the show depicts occasional alternatives during specific storylines. Nevertheless, the standard and best-known walking aid associated with the character is a cane.
