Abstract: A kit of modular prosthetic hip components includes a first neck having a coupling element thereon. First and second hip stems each have a coupling element at a proximal end thereof for connecting to the coupling element of the first neck. The first and second hip stems have a progressively larger medial-lateral dimension in a proximal portion thereof. The coupling element on each of the first and second hip stems is located at a different medial-lateral location thereon with the coupling element located more medially and proximally on the second stem than the first stem. The first neck forms an identical first neck angle with a proximal-distal axis of the respective first and second stems. The coupling elements on the first and second stems locate a head mounted on the first neck in the same proximal-distal location but a different medial-lateral location with respect to an acetabulum.
