Femoral Neck System versus Cannulated Screws in Management of Fracture Neck Femur in Adults

Abstract Background Femoral Neck Fractures (FNF) accounts for about 3.6% of adult fractures, which is one of the more common fractures in the body. FNF is more common in elderly patients, generally refers to the fracture in the part of the femoral head down to the base of the femoral neck. Garden classification is often adopted for FNF in the elderly, type I and type II, because no displacement or displacement of fracture end to a lesser degree, damage degree of fracture is lesser, belongs to the stable fractures. Aim of the Work To review systematically studies about the use of Femoral Neck System versus Cannulated screws in management of non displaced femoral neck fracture in elderly. Materials and Methods We prepared this systematic review with a careful following of the Cochrane Handbook for Systematic Reviews of Interventions. We also adhered to The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines during the design of our study. Results This meta-analysis compared the clinical outcomes of FNS and CS fixation for femoral neck fracture in young adults. The study found that FNS is superior to CS in terms of intraoperative fluoroscopies, weight-bearing time, Harris Hip Score, total complications, femoral neck shortening, and nail retreat. However, the two fixation methods were similar in terms of the operation time, length of hospital stay, healing time, intraoperative blood loss, non-union, femoral head necrosis, and internal fixation cut-out. From the perspective of surgical outcomes, intraoperative fluoroscopies were used less in FNS fixation than in CS fixation. Conclusion Femoral neck system fixation shows improved outcomes compared to the cannulated screw fixation for neck femur fractures regarding intra operative surgery, prognosis and reduced complication rates, more Studies and RCTs for this new fixation method are needed to obtain more conclusive results.
