An implant (1) for modifying the tissue deformation during bone healing between two bone fragments (5； 6), with a first end piece (2) that can be fastened to a first bone fragment (5) with a longitudinal axis L1, and a second end piece (3) that can be fastened to a second bone fragment (6) with a longitudinal axis L2, wherein the first and second end pieces (2； 3) are loosely meshed with one another by means of n≥1 parallel-connected tissue activators (4a； 4b) in each case to allow relative movement and the tissue activators (4a； 4b) are arranged to be perpendicular to the longitudinal axes L1 and L2 and preferably orthogonal thereto.
