ABSTRACT
OBJECTIVE:
To report upon a series of patients who have experienced the backout of distal interlocking screws after retrograde femoral nailing with the DePuy Synthes RFN-Advanced Retrograde Femoral Nailing System (DePuy Synthes, Raynham, MA).DESIGN:
Retrospective case series. PATIENTS Twenty-seven skeletally mature patients with femoral shaft or distal femur fractures who underwent operative fixation with the DePuy Synthes RFN-Advanced Retrograde Femoral Nailing System with 8 patients subsequently experiencing backout of distal interlocking screws. INTERVENTION The study intervention included retrospective review of patient charts and radiographs. MAIN OUTCOMEMEASURE:
The incidence rate of distal interlocking screw backout.RESULTS:
Thirty percent of patients experienced the backout of at least 1 distal interlocking screw (mean 1.625) after undergoing retrograde femoral nailing with the RFN-Advanced system. Thirteen total screws backed out postoperatively. Screw backout was identified an average of 61 days postoperatively (range 30-139 days). All patients complained of implant prominence and pain along the medial or lateral aspect of the knee. Five patients elected to return to the operating room to remove the symptomatic implant. The oblique distal interlocking screws comprised 62% of screw backouts.CONCLUSIONS:
Given the high incidence rate of this complication, the associated costs of reoperation, and patient discomfort, we believe that a further investigation into this implant complication is warranted. LEVEL OF EVIDENCE Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.
