JOINT FUSION APPARATUS FOR THE ANKLE-TYPE JOINT AND ARTHRODETIC PIN FOR USE IN SAID APPARATUS

摘要

The invention relates to an arthrodetic apparatus for a first and second bone (2, 3), comprising a pin (5), an instrument (20) for positioning said pin (5) comprising a base (21) and a compression means (22, 23) with an operating means (22) to produce a displacement of the pin relative to the base (21) and an immobilisation means (23) for the second bone (3) relative to the base (21), whereby said pin comprises a guidance means (11). Said guidance means (11) and said immobilisation means (23) are embodied and arranged to cooperate together such as to permit the displacement of the pin relative to the immobilisation means (23) and the approach of the first bone (2) to the second bone (3). The invention further relates to arthrodetic apparatuses.
