The aim of the presented cadaveric study is to illustrate an innovative concept of internal fixation, named F.E.R.I. In this group of patients, internal fixation is often required to obtain a satisfactory outcome and time to return to play. Conclusionsįifth metatarsal base fractures gain specific interest when occurring in athletes. The authors intend to study this technique in the clinical setting in the near future. technique is indicated in acute proximal fractures, stress fractures or non-union of metatarsal 5 (Zone 2–3 by Lawrence and Botte) and it resulted feasible and stable during manual stress test. In this article, the cadaveric study and proposed surgical technique are explained and illustrated step by step. On a cadaver, through two mini portals, a full reduction and solid internal fixation with an intramedullary screw and suture cerclage with Fiberwire of a fifth metatarsal base fracture is achieved. (Fifth metatarsal, Extra-portal, Rigid, Innovative) technique. These reports prompted us to look at new materials and a novel technique through fixation with an intramedullary screw combined with a high-resistance suture via the presented F.E.R.I. One of the main problems of Kirschner wire fixation of fifth metatarsal base fractures (in combination with a tension band wiring technique) seems to be hardware intolerance and several studies in athletes also report failure after isolated fixation with a screw only.
