Surgical procedure
CAVITY
Surgeons recruited in the study had previous experience with cephalomedullary nailing. The surgical procedure was a closed reduction (and/or open reduction if needed) under fluoroscopy. The implantation of both nail systems is similar involving opening of the medullary cavity, insertion of the nails and head assembly, distal locking, and insertion of the end cap (if desired). While the TFNA is available with both screw and blade head elements, the PFNA II is only available with a helical blade head element.
