Vascular Injury with Insertion of Anteroposterior Interlocking Screw of Retrograde Femoral Nail - Case Report.

Department of Orthopaedic Surgery, Worcestershire Royal Hospital, Charles Hastings Way, Worcester, WR5 1DD, United Kingdom.
Introduction: Retrograde femoral nailing is a frequently performed surgical procedure used to stabilize a supracondylar femur fracture. We are reporting a unique case where the insertion of the anteroposterior interlocking screw of a retrograde nail caused vascular damage. Within the elderly patient population, we anticipate the presence of significant collateral blood vessels, which increases the potential for vascular damage during the insertion of a proximal screw.

Objectives: To assess the biomechanical differences between linked and unlinked constructs in young and osteoporotic cadavers in addition to osteoporotic sawbones.
Methods: Intraarticular distal femur fractures with comminuted metaphyseal regions were created in three young matched pair cadavers, three osteoporotic matched pair cadavers, and six osteoporotic sawbones. Precontoured distal femur locking plates were placed in addition to a standardized retrograde nail, with unitized constructs having one 4.
Rates of interlock screw back-out are high with the retrograde femoral nailing advanced system for distal femur fractures.

Purpose: The retrograde femoral nailing advanced (RFNA) system (DePuy synthes) is a commonly used implant for the fixation of low distal femur and periprosthetic fractures. There is concern that the rate of distal interlock screw back-out may be higher for the RFNA compared to other nails (ON). The purpose of this study was to evaluate the incidence of interlock screw back-out and associated screw removal for RFNA versus ON, along with associated risk factors.

Introduction: In literature, there have been many studies conducted to research the alternatives of standard interlocking intramedullary nailing. The expandable wedge locked nail fixation, which is thought as a new alternative to the standard interlocking nailing, has been presented in previous numerical studies. The antegrade usage of the wedge locked nail fixation has provided promising results.
