Anatomic Locked Plating System 4 mm cancellous locking screws - used to treat broken bones
Hazard alert - risk of soft tissue irritation and potential need for revision
Consumers and health professionals are advised that Zimmer Biomet, in consultation with the TGA, is issuing a hazard alert about Anatomic Locked Plating System (ALPS) 4 mm cancellous locking screws. The sponsor is also recalling unused stock of affected devices.
ALPS 4 mm cancellous locking screws are used with an orthopaedic fixation plate to treat broken bones.
It has been identified that all lots of ALPS 4 mm cancellous locking screws manufactured between 1 June 2008 and 4 June 2015 (see below for list of affected part numbers) have a single lead thread instead of a triple lead thread.
A single lead thread may 'sit proud' in the plate, meaning the head of the screw sits above the surface in which it is fixed. If this happens, soft tissue irritation may occur.
If the screw does not lock into the plate, it is possible for the screw to back out. If this happens, revision surgery to correct the problem may be necessary.
