PHILOS Instrument Upgrade
One of the main complications in proximal humeral plating is primary screw perforation. Primary screw perforation happens if too long screws are set at the time of surgery, despite intraoperative image intensifier control. Using measuring notations on drill bits and K-wires seems inadequate for achieving reliable screw length in osteopenic bone. Therefore, dedicated instruments were developed to drill the lateral cortex only, followed by the use of a depth probe to feel the resistance of the subchondral bone in these patients.
Additionally, the new proximal suture holes on the PHILOS plate are penetrating the plate from the top to the sides, allowing the attachment of the suture after the plate has been fully mounted to the bone.
