Rhombic 3D | advanced geometry for a complex problem

Condylar process fractures surely are among the greatest challenges in traumatology.

The significant degree of dislocation, confined spaces, and close proximity to major blood vessels and nerves are factors that contribute to the overall stress and time involved in the surgical treatment.

    With the Rhombic 3D Condylar Fracture Plate, the KLS Martin Group now offers an aid that is well adapted to the multi-linear masticatory forces affecting such fractures. 

    •    Can be used for the surgical treatment of deep, medium
          and high condylar process fractures.

    •    The rhombic shape of the plate provides for optimal transmission
          of the tensile and compressive forces present in the mandible.

    •    Closely positioned screw holes in the proximal part of the plate
          allow secure placement of the osteosynthesis screws even under
          difficult spatial conditions.

    lateral sliding-repositioning holes

    The Rhombic 3D Gliding-Reposition version offers the special advantage of lateral gliding holes for final repositioning of the bone fragments after the superior osteosynthesis screws have been secured in the condyle.

    After the condyle is in a satisfactory position, the gliding hole screws are tightened and a final screw is placed in the inferior hole.

    ThreadLock Taper Screw (TLTS)

    The Rhombic 3D ThreadLock TS version offers the special advantage of the Taper-Screw locking screw feature. This allows rigid fixation without perfect adaptation of the plate to the bone. Not only does the plate not have to be perfectly passive against the bone, but the screws will lock into the plate at even a 20 degree angle.

    The approach with a locking plate also reduces the chance of loose hardware and chances of bone remodeling due to compression against the bone surface.
