Acetabular bone reamer Concave and Convex System

The Astrolabe Concave and Convex Reamer System is indicated to facilitate reproducible joint surface preparation for arthrodesis procedures in hammertoe, claw toe, and mallet toe deformity correction.

The system comprises a cannulated concave and convex reamer set designed to create a complementary hemispherical joint interface. This preparation technique enhances surface contact area, promotes intrinsic stability at the fusion site, and supports accurate alignment prior to definitive fixation.

The cannulated configuration allows guided use over a wire, ensuring precise positioning and controlled bone preparation, thereby contributing to reliable arthrodesis and favorable conditions for osseous consolidation.
