Lower-risk recall

Stryker has identified a nonconformance in specific lots of Hoffmann LRF Bone Transport Struts. Specifically, the thread pitch is oversized at the distal end of the threaded rod, and as a result the distal ring fixation cannot be locked between 0- 50mm of the threaded rod.

✎ GovInfoNow plain-language explainer

Stryker is recalling specific models of orthopedic external fixation devices (Hoffmann LRF Bone Transport Struts) because the threaded rod has an oversized thread pitch at the distal end. This prevents the distal ring from locking securely between 0-50mm of the threaded rod, potentially leading to improper bone fixation.
