A femoral intramedullary nail is a metal rod which is inserted into the femoral canal to stabilize fractures of the long bone. The retrograde femoral nail is a type of intramedullary nail which is inserted at the distal end of the long bone and is typically used for distal femur fractures. While the success rates are high, some complications still exist, including failure of the nail through the screw holes, failure or loosening of screws, and bone fracture [1]. There are many design variables that affect clinical performance including the implant material, nail and screw diameters, the number of screws, and the nail and screw position and orientation. To help determine the most suitable design for a given fracture the effect of the above variables on the stresses and displacements in the nail, screws, and bone may be important to consider.

Abstract Purpose This study reviewed the literature regarding the patient-reported treatment outcomes of using either open reduction and internal fixation (ORIF) with a plate and screw system or intramedullary nail (IMN) fixation for periprosthetic distal femur fractures around a total knee arthroplasty. Methods A total of 13 studies published in the last 20 years met the inclusion criteria. The studies included 347 patients who were allocated to ORIF (n = 249) and IMN (n = 98) groups according to the implants used. The primary outcome measures were the Knee Society Score or the Western Ontario and McMaster Universities osteoarthritis index. The secondary outcome measures included knee range of motion and the rates of complications, including non-union, malunion, infection, revision total knee arthroplasty, and reoperation. Statistical significance was set at P < 0.05. Results The mean Knee Society Scores of ORIF and IMN groups were 83 and 84, respectively; the mean postoperative range of motion of the knee were 99° and 100°, respectively (P < 0.05); the non-union rates were 9.4 and 3.8%, respectively (P > 0.05); the malunion rates were 1.8 and 7.5%, respectively (P < 0.05); surgical site infection rates were 2 and 1.3%, respectively (P > 0.05); the reoperation rates were 9.6 and 5.1%, respectively (P > 0.05); and revision rates of total knee arthroplasty were 2 and 1%, respectively (P > 0.05). Conclusion Based on the patient-reported outcome assessments, both ORIF with a plate and screw system and IMN fixation are well-accepted techniques for periprosthetic distal femur fractures around a TKA, and they produce similar functional outcomes.

A Prospective Study

Background: The optimal treatment of complex distal femur fractures always remains challenging and controversial. The purpose of this prospective study was to evaluate the efficacy of distal femoral locking compression plate (DF-LCP) in terms of functional outcome, and union rate for highly unstable or complex distal femurfractures and to determine the influencing factors of an unfavorable outcome. Methods: After obtaining approval from the institutional ethics committee, 58 patients with complex distal femur were managed by open reduction and internal fixation with DF-LCP through lateral approach and as per standard protocol. The follow-up results were analyzed clinically and radiologically, using the “ Schatzker and Lambert criteria” at once in a month for the first three months, once in three months upto one year and once in six months after that up to two years.

Abstract Introduction: Adequate treatment for periprosthetic distal femur fractures is challenging because of various reasons, including severe osteoporosis and distal fragments that are too small or too distal. We have introduced a new surgical technique for dual plating of periprosthetic distal femur fractures following total knee arthroplasty (TKA) and determined the clinical and radiological outcomes of minimally invasive plate osteosynthesis (MIPO) with a dual locking compression plate (LCP). Materials and methods: Between January 2010 and July 2019, 18 patients [mean age, 74.8 (68–89) years; average follow-up period, 14.8 (12–43) months)] underwent MIPO with distal femoral LCP laterally and proximal humeral internal locking system (PHILOS) medially for periprosthetic distal femoral fractures following TKA. The minimum follow-up was one year. The clinical and radiological outcomes were assessed using the modified WOMAC scores, knee range of motion, time to callus formation, time to union, and complications of malunion, nonunion, and shortening.Results: The average time to union was 18.4 weeks (range, 10–51 weeks) and to callus formation was 7.8 weeks (range, 2–14 weeks). At the one-year follow-up, the average JLETS was 37.6 (range, 24–53), average knee ROM was 110.3° (range, 80°–135°), and average varus-valgus angles of the distal femur were 3.2° (range, -2.9°–10.5°). No nonunion, broken plates, or implant failure occurred. Malunion occurred in three patients.Conclusion: MIPO with dual LCP is a reliable method for stabilizing periprosthetic distal femoral fractures following TKA, with satisfactory bone union rates and low complication rates.
