Zhang Y, et al. - Researchers reported the reverse wedge effect following intramedullary nailing of a basicervical trochanteric fracture variant combined with a mechanically compromised greater trochanter. This study enrolled a sum of 414 trochanteric fractures (TF) treated with intramedullary nails from 2013 to 2017. They determined 33 cases, including 21 females and 12 males, with a mean age of 72.5 years (33 to 96 years) for internal rotation of the cephalocervical fragment and inferior opening at the basicervical fracture line caused by nailing a satisfactorily reduced TF after analysis of intraoperative fluoroscopy data. They examined morphological features of this group of patients on computed tomography (CT) scan. The study found that unreported intraoperative complication predominantly occurred in the intramedullary nailed basicervical trochanteric fracture variant combined with a PLF from the GT. It is demonstrates that the magnitude of the secondary displacement was substantial and resulted in a relative valgus reduction. The causation of this secondary displacement was by an impingement of the reamer with the superolateral cortex of the cephalocervical fragment and should be addressed during the operation.
