摘要：
An implant comprises a deformable gas tight sack. The sack comprises a first chamber in fluid communication with an obturatable opening, the chamber filled or fillable with a filling material filling the first chamber. The implant is configured such that when one or both of a gas and fluid surrounding the filling material is removed from the first chamber through the opening, a wall of the first chamber forms around and holds the filling material. This causes the implant to transition from a relatively flexible insertion state to a relatively rigid fixation state in which the implant is fixable in the target portions of bone.
