An implant assembly including a main implant and a secondary implant to fix the main implant in a relative position. The secondary implant being passable into a unprepared bone structure to securely fix the main implant in place. The secondary implant including a conduit to flow a flowable material that is able to securely interconnect the secondary implant with the bone structure.

Method and apparatus for cement delivering buttress pin

A fixation device, such as a bone screw, includes a bioresorbable proximal shaft portion and a non-bioresorbable distal threaded portion. In one aspect, the shaft portion is provided with a longitudinal throughbore which is aligned with a corresponding longitudinal bore in the proximal region of the threaded portion. A driver mechanism is employed to impart a rotary force so as to enable the device to be inserted into bone tissue. Afterwards, the driver mechanism is withdrawn from the respective bores. In another aspect, the non-bioresorbable distal portion is a substantially elongated solid member and includes a threaded distal region and a shaft-like proximal region. The comparatively smaller bioresorbable proximal region can mate with the distal portion either after or before the distal portion has been inserted into the bone tissue.
