Zimmer Biomet Hip Screw Recall: Confusing Screw Sizes May Cause Errors
Zimmer Biomet recalls hip screws that may be mislabeled as 20mm when they are 30mm, risking surgical errors. Affected units include specific lot numbers. Contact for replacement.
Two lengths of the 6.5mm RingLoc Hip System Self-Tapping Bone Screw may have the potential for the 30mm screws to be packaged as 20mm screws and vice versa.
