Multicenter StudyImplant Fracture Analysis of the TFNA Proximal Femoral Nail.
Mechanical failure of intramedullary nails is rare. This investigation was prompted by a series of cases of observed breakage of the recently introduced TFNA Proximal Femoral Nailing System (TFN [Trochanteric Fixation Nail]-Advanced; DePuy Synthes) in our region. Laboratory analysis and case data are presented, in contribution to post-market surveillance. ⋯ Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
