House has lost his flame cane and sustained head injury in a bus crash. While having his head wound stitched by Cameron, he reaches lazily for a crutch, which Wilson obediently gets for him. |

Last Appearance: House's Head [S04-E15]  | 
House has an unpopular theory about the POTW, so he locks himself and Thirteen into a room with the patient using the crutch to jam the sliding door closed. On Cuddy's orders, Foreman and Kutner force the door open, breaking the crutch in the process. |

| Continuity | When House first acquires the crutch, the adjustable-height armband is at its lowest setting. In later scenes, however, it is at the highest setting. This might not qualify as an error - it is perfectly reasonable to assume that House could have adjusted it at some point between scenes to make it more comfortable. If that is indeed the case, it's a nice little detail. |
