Abstract
An ankle arthrodesis fusion plate is provided that affords compression across the tibio-talar joint to promote bone fusion and joint stability.
Claims18
A fusion plate suitable for receiving bone anchors for use in tibiotalocalcaneal or tibiocalcaneal arthrodesis comprising:
- a shaft having a proximal portion, a distal portion, a longitudinal axis, and a plurality of through-bores defined within said proximal portion wherein a transverse contour of said proximal portion is defined by a first radius and a longitudinal contour of said proximal portion is defined by a first angle, wherein said first angle and said first radius are selected so as to provide effective positioning of said proximal portion for at least one of tibiotalocalcaneal and tibiocalcaneal fixation;
- said distal portion arranged so as to be flared away from said longitudinal axis said flare being defined by a second angle, and including a plurality of eyelets each being suitable for receiving a bone anchor and that are each offset from said longitudinal axis wherein a transverse contour of said distal portion is defined by a second radius wherein said second angle and said second radius are selected so as to provide delimited angulated access of said bone anchor to each said eyelet such that each said bone anchor may achieve effective bone purchase and thereby secure at least one of tibiotalocalcaneal and tibiocalcaneal fixation.
A fusion plate suitable for receiving bone anchors for use in at least one of tibiotalocalcaneal and tibiocalcaneal arthrodesis comprising:
- a shaft having a proximal portion, a distal portion, a longitudinal axis, and a plurality of threaded through-bores defined within said proximal portion wherein a transverse contour of said proximal portion is defined by a first radius and a longitudinal contour of said proximal portion is defined by a first angle, wherein said first angle and said first radius are selected so as to provide effective positioning of said proximal portion for at least one of tibiotalocalcaneal and tibiocalcaneal fixation;
- said distal portion arranged so as to be flared away from said a longitudinal axis said flare being defined by a second angle, and including a plurality of eyelets each being suitable for receiving a bone anchor and that are each offset from said longitudinal axis wherein a transverse contour of said distal portion is defined by a second radius that is less than said first radius wherein said second angle and said second radius are selected so as to provide delimited angulated access of said bone anchor to each said eyelet such that each said bone anchor may achieve effective bone purchase and thereby secure tibiotalocalcaneal fixation.
