Most surgically treated fractures do not require locking plate fixation. As long as the principles of orthopedic surgery are followed, most fractures can be healed by traditional steel plates or intramedullary nails.
Placement of locking plate
1. Screw the drill sleeve into the screw hole of the steel plate. If the deviation between the screw and the screw hole is more than 5°, the screw will fail to lock. It is recommended to use the drill sleeve to drill the hole.
2. Place the steel plate on the surface of the bone and drill through the drill sleeve.
3. Use a depth sounder to measure the depth, and pay attention to inserting the head of the depth sounder into the screw hole.
4. Choose locking screws of appropriate length.
5. The operation of installing pressure screws is the same as that of ordinary steel plates.
6. Finally, tighten the locking screw with a torque wrench. When tightening, there will be a noticeable sliding feel and a rattling sound, so as to avoid over-tightening and difficult removal.
Locked steel plate removal
Although locking plate screws are widely used clinically, they are prone to difficult removal, which is mainly manifested as screw threading and cross-threading between the nail cap and the plate nail hole.
