Abstract

The use of an occlusive or semi-occlusive membrane is described for promotion of bone growth in orthopaedic surgery, wherein a bone injury is sealed by closing the injury with a membrane which is substantially inert to body fluids and is adapted to prevent ingrowth of fibrous tissue into said injury. Preferably, the membrane is a laminate of at least two layers comprising a first layer having openings of a size which are adapted to be penetrated by fibrous soft tissue, and a second layer which is non-porous or has pores which are too small to be penetrated by soft tissue, the second layer being adapted to lie adjacent the bone injury.
