Provided herein are hip implant devices and related surgical methods. The hip implants and methods can optionally be used in patients of Asian descent.

Hip implant

Provided herein is a femoral component of a hip implant device, comprising a neck having a central axis; and a body distal to the neck and having a tapered portion, wherein the body has a largest cross section perpendicular to the neck central axis, the largest cross section perpendicular to the neck central axis having a maximum height dimension and a maximum width dimension, wherein the maximum width dimension is 18.5 mm or less. The hip implant can optionally be used in patients of Asian descent.

Provided are acetabular cup implant assemblies that can be used in hip replacement surgery. Example assemblies comprise a shell and a liner. The liner can be positioned within a shell. Optionally, the liner can be rotated relative to the shell until the liner is seated in the shell in a position where the liner and shell can be secured to one another. Waveform-shaped features of the shell and liner can guide the relative rotation of the liner and shell. Also provided are methods of seating a liner in shell of an acetabular cup implant assembly.
