This report is being filed after the review of the following journal article: codesido, p., mejía, a., riego, j., ojeda-thies, c.(2017), subtrochanteric fractures in elderly people treated with intramedullary fixation: quality of life and complications following open reduction and cerclage wiring versus closed reduction, archives of orthopaedic and trauma surgery, vol.137, pages 1077¿1085 (spain).The aim of this prospective cohort and retrospective observational study is to compare the results in fragility-type subtrochanteric fractures treated with cephalomedullary nails, after minimal open reduction assisted by cerclage wires, with those observed following closed, indirect reduction (as chosen by the surgeon at the time of surgery), with special emphasis on hrqol, quality of reduction, and postoperative orthopaedic complications.Between january 2009 to december 2012, a total of 90 patients (17 male and 73 female) with a mean age of 83.52 (±7.87) were treated with cephalomedullary nails.These patients were divided to 2 different groups: one treated with closed or percutaneous reduction maneuvers (60 patients) and another using open reduction and cerclage wires (30 patients).Only 2 patients were implanted with pfn nail (synthes, west chester, pa) with no cerclage wires and the rest were implanted with a competitor device.All patients had a minimum 2-year follow-up.The following complications were reported as follows: an unknown number of patients achieved poor reduction.1 patient had a superficial infection.Case 1 had varus malposition of the fracture.An unknown number of patients had nonunion.An unknown number of patients had a peri-implant fracture.An unknown number of patients had cut-out needing reoperation.An unknown number of patients died after 1-year.This is report 3 of 3 for (b)(4).This report is for an unknown synthes pfn constructs.
