Fixation device for the fixation of bone fragments

A method of manufacturing a device for fixating a cranial bone flap with a cranial bone mass, the method comprising:

• forming a monolithic body with a substantially planar configuration that comprises a support plate with an inner surface that is adapted to be applied against the inner face of the outer edges of the cranial bone mass and the cranial bone flap, the support plate having first and second peripheral edges, the monolithic body further comprising a first flexible strip segment that extends from the first peripheral edge and a second flexible strip segment that extends from the second peripheral edge,
• forming a closure plate with an inner surface, the inner surface adapted to be applied against the outer face of the outer edges of the cranial bone mass and the cranial bone flap, the closure plate being formed with first and second openings extending there through, each of the first and second openings formed to respectively receive the first and second flexible strip segments, each of the first and second openings formed with an interlocking feature that permits the passage and movement of the first and second flexible strip segments in a first direction through the respective first and second openings while preventing movement in a second direction opposite the first direction;
• and
• inserting the first and second flexible strip segments through the respective first and second openings of the closure plate to form with the support plate a closed loop, the closure plate being moveable along the first and second flexible strips in a direction toward the support plate.
