摘要
The assembly has a cylindrical compression screw (1) e.g. Herbert screw, including a smooth intermediate portion (6) between threaded ends (2, 4). A longitudinal central opening hole (7) allows a passage of a metallic guide pin. A cylindrical filling rod (9) closes the hole on a part of its length after insertion of the screw in a bone e.g. scaphoid bone, and withdrawal of the pin, where the rod has a diameter smaller than that of the hole. The screw and the rod are made of biodegradable and resorbable material e.g. cellulose and starch.
