Description
Carlos Lucero and three co-authors report a rare case of hip implant stems breaking on both sides in a patient with a particular thigh bone shape. Their report came out in 2025. The shape, called Dorr A, has a narrow canal, which changes how stress concentrates in an implant stem.
The first failure involved a cemented revision stem placed with a cement-within-cement technique after a bone cut along the thigh. A second revision used a different bone window and an uncemented stem fixed lower down, and it succeeded. The same approach later fixed the other side, also with a good result. The authors argue that standard cemented stems can be oversized in narrow canals. They advocate individualized implant choices, including shorter or modular stems, for this anatomy.
