Overview

In primary total hip arthroplasty, the acetabular side needs a shell that can be placed as planned. It may need screw fixation, and it needs a liner that stays locked. The HECTOR acetabular system pairs a hemispherical shell with cross-linked polyethylene (XLPE) liners.

Design rationale

Three-hole hemispherical shell

The shell is hemispherical, with three screw holes and a polished inner surface. Its outer surface carries the titanium plasma and HA coating. Pilot holes are drilled through a variable-angle drill guide.

Screw angulation and length

The spherical head of the acetabular screw allows angulation of up to 15° in the hole. After drilling, a depth gauge reads the hole, so the length is chosen before the screw is driven.

Double-locking XLPE liner

The liner is cross-linked polyethylene with a double locking mechanism. Its ears are intended to stop it rotating in the shell. A liner, once impacted into its shell, should not be reassembled. The locking design still allows a new liner to be fitted to a shell already in place, during surgery or at revision.

Elevated-rim 20° liner

The 20° liner has an elevated rim that is placed where the hip tends to dislocate.
