Abstract
A bone void forming assembly includes a support member having a head portion and an elongate portion extending therefrom. A guide member is connected to the support member and has a guide body including a channel extending therethrough. The channel defines an axis offset and obliquely angled relative to an axis of the elongate portion. The assembly also includes reamer having a cutting head and a stop member. A bushing is slidably connected to the reamer between the stop member and cutting head and is slidably connectable to the guide body via the channel.
Claims17
A bone void forming assembly, comprising:
- a support member having a head portion and an elongate portion extending from the head portion;
- a guide member connectable to the support member and having a guide body including a channel extending therethrough and a slot extending through the guide body along a length thereof and being in fluid communication with the channel, the channel defining a body axis offset relative to an axis of the elongate portion when the guide member is connected to the support member;
- a reamer having a stop member;
- and
- a bushing slidably connected to the reamer between the stop member and a cutting head thereof and to the guide body via the channel, the bushing having an outer dimension larger than a width of the slot such that the bushing is prevented from being passed through the slot and into the channel therefrom.
A bone void forming assembly, comprising:
- a support member having an end portion configured for insertion into an end of bone;
- a guide member connected to the support member, the guide member having a sidewall defining a channel sized to receive the bushing and a slot extending through the sidewall so as to communicate with the channel, the bushing having an outer dimension larger than a width of the slot such that the bushing is prevented from being passed through the slot and into the channel therefrom;
- and
- a reamer assembly connected to the support member via the bushing, the reamer assembly having a reamer and a bushing slidably connected to the reamer.
A bone void forming apparatus, comprising:
- a support member having an elongate portion;
- a guide member connected to the elongate portion and having an inner surface and an outer surface defining a sidewall therebetween, the inner surface defining a channel extending through a length of the guide member, the guide member further defining a slot extending through the sidewall and being in communication with the channel;
- a reamer having first and second ends and a cutting portion disposed therebetween;
- and
- a bushing slidably connected to the reamer between the first and second ends thereof, the bushing having an outer dimension smaller than a dimension of the channel so as to allow the bushing to slide into the channel from a first end of the guide body, the outer dimension of the bushing being larger than a width of the slot such that the bushing is prevented from being passed through the slot and into the channel therefrom.
