Zusammenfassung:	An acetabular device includes a patient-specific acetabular alignment guide (400) including a bone engagement surface (408). The bone engagement surface has a first portion (402) configured and shaped to be conforming and complementary to an acetabular rim surface (84) and a second portion (404) configured and shaped to be conforming and complementary to a periacetabular area of an acetabulum (82) of a patient. The acetabular alignment guide includes a plurality of guiding formations (406) extending through the second portion for guiding a oplurality of alignment pins (420) therethrough. The bone engagement surface and the plurality of guiding formations are prepared from a three-dimensional model of the acetabulum of the specific patient reconstructed pre-operatively from a scan of the patient.
