1. A surgical tray apparatus and components thereof configured for use in hip replacement surgery comprising:
trial implants for sizing, locating and implanting a reverse hip acetabular cup including at least two differently sized trial acetabular cups each having a hemispherical outer surface and an inner concave surface, optionally one or more through openings extending through the trial acetabular cups, the inner concave surface having an internally threaded stem, the stem having a height and extending from the inner concave surface and extending to an end having an opening, and at least two differently sized first trial acetabular balls each having a threaded portion removably engageable via mating threads within the internally threaded stem of a trial acetabular cup such that when fully engaged a part of the trial acetabular ball abuts the end of the stem, and an opening centered in a flattened portion of the trial acetabular ball opposite to the threaded portion, the opening being sized and shaped to receive a tool for tightening and loosening the trial acetabular ball when the threaded portion is engaged with the mating threads of the stem of a trial acetabular cup,
two or more than two trial femoral cups configured to be temporarily affixed to the proximal end of a broach or a femoral implant engageable with at least one of the first trial acetabular balls, each of the trial femoral cups having a base portion and a concave portion configured to articulate on a trial acetabular ball engaged with the stem of a trial acetabular cup;
and optionally,
at least one further article selected from: at least one tool, a press, a femoral cup locator and a plunger for pressing a polymer liner into a femoral cup.
