Modular articulating cement spacer

摘要

The present teachings provide a modular articulating cement spacer mold for forming a temporary implant comprising a mold first portion, a mold second portion, and a ventilation forming surface feature on an interior surface of at least one of the mold first portion or the mold second portion. The first mold portion and the second mold portion have corresponding interior surfaces that form a cavity therebetween.

主权项

1. A modular articulating cement spacer mold system for forming a temporary implant comprising:
a mold first portion extending from a first end to a second end and having a first plurality of open hooks formed on and extending away from a first exterior surface of the mold first portion; a mold second portion extending from a third end to a fourth end and having a second plurality of open hooks formed on and extending away from a second exterior surface of the mold second portion; both the mold first portion and the mold second portion have respective and corresponding interior surfaces defining a cavity therebetween; a connection component pin extending between at least a first hook of the first plurality of open hooks and at least a second hook of the second plurality of open hooks; a self-cleaning cap configured to be inserted into an opening formed by at least one of the first mold portion or the second mold portion, wherein the self-cleaning cap includes a threaded region, a closed bottom, an interrupted hollow region, and a recessed containment region, wherein the opening further includes a threaded opening, wherein the threaded region mates with the threaded opening and as the self-cleaning cap is advanced through the threaded opening any excess material passes around the closed bottom of the self-cleaning cap and through the interrupted hollow regions into the recessed containment region of the self-cleaning cap; a plurality of surface features that include raised dimples and raised linear dashes extending from the interior surfaces; and a ventilation forming surface feature on the interior surface of at least one of the mold first portion or the mold second portion; wherein the temporary implant is a femoral stem formable in the cavity.
