Recall and hazard alert

4 July 2013

Consumers and health professionals are advised that Synthes Australia, in consultation with the TGA, is recalling unused stock of its 3.7 mm and 5.0 mm Dynamic Locking Screws. Synthes Australia has also issued a related hazard alert to hospitals and surgeons.

Dynamic Locking Screws are used with an orthopaedic fixation plate to treat fractures of long bones.

It has been identified that the distal tip (the end furthest from the head) of the 3.7 mm and 5.0 mm Dynamic Locking Screws can potentially break.

If this occurs, it could increase the time in surgery needed to remove the screws and could result in injury to the patient, such as soft tissue damage. While unlikely, a breakage could require additional surgery.

Please note that there have been no adverse events relating to this issue reported in Australia.

The part numbers for the affected products are:

  • 09.213.022S–09.213.070S for Dynamic Locking Screws 3.7 mm (all lots)
  • 09.223.032S–09.223.090S for Dynamic Locking Screws 5.0 mm (all lots)

Synthes Australia has contacted surgeons and the hospitals where the affected Dynamic Locking Screws have been used, providing further information regarding this recall and advice on how to treat affected patients.

If you have had an orthopaedic fixation plate implanted to treat a fracture of a long bone and have any questions or concerns about this issue, contact your surgeon or the hospital where the surgery was undertaken.
