A prosthesis for correction of a flatfoot condition, designed for insertion inside a tarsal sinus defined between an astragalus bone and the calcaneous, which comprises:
- a first cylindrical body having a deformable wall wherein said body is formed of a bioreabsorbable polymeric material and sized to be axially inserted into said tarsal sinus, said first body having an axial hole defined by said deformable wall, and
- a second substantially cylindrical body formed of said bioreabsorbable polymeric material and sized to be axially inserted into said hole to deform said wall as to increase the outer diameter thereof, such that the prosthesis is adjusted according to the size of said tarsal sinus when the prosthesis is surgically inserted into said tarsal sinus to achieve a given position of a longitudinal axis of the astragalus bone in relation to a longitudinal axis of the calcaneus.
