Mechanical Failure and Revision Risk Following Transition from PFNA to TFNA: A Single-Center Cohort Study of 1,970 Patients.
Journal of orthopaedic trauma·October 9, 2026·PMID 42854683
Why it mattersImplant choice for intertrochanteric fractures directly affects reoperation risk and patient morbidity. The observed higher failure and cut-out rates with TFNA, despite similar tip-apex distance, suggest potential differences in mechanical stability that warrant attention during implant selection and postoperative surveillance.
