Surgical technique
Four screw extraction methods

Extracting screws requires experience and expertise. The OPERACE instrument set may be used only by trained operators.


1. Removal of intact screws.

2. Removal of screws with a damaged screw recess.

3. Removal of locking head screws stuck in the plate.

4. Removal of broken screws and of screws processed according to procedure 3.


The correct instrument sizes to remove screws must be carefully chosen to facilitate screw extraction and to reduce the risk of further screw damage during the procedure. Supplementing the information in this manual, instruction in the surgical use of these instruments by a surgeon experienced in their handling is strongly recommended.
