Comparison between Three Cannulated Screws and Targon Locking Plate for Displaced Intracapsular Hip Fracture: A Retrospective Study

Le résumé fourni par la source

Abstract Purpose: The aim of this retrospective study was to compare the clinical and radiological outcomes between three cannulated screws (TCS) and two cannulated screws combined one fully threaded cannulated screw with TARGON locking plate (TCS-TLP) for the displaced intracapsular hip fracture.Methods: 75 patients underwent displaced intracapsular hip fracture were treated with operation from January 2013 to January 2019. 35 patients underwent TCS-TLP and others 40 patients treated with TCS. Injuries were assessed based on AO classification, and the outcomes measurements including modified Harris hip score (MHHS), visual analogue score (VAS) and the radiological data.Results: There were significantly better MHHS improvement in the TCS-TLP group than TCS group at the 12 months (85.6 VS 75.6, P<0.05) and 24 months (89.4 VS 81.1, P<0.05). And a total of 5 patients had complications in TCS-TLP group whilst 14 cases in the TCS group (P<0.05), similarly, the femoral neck shorten rate was significantly less in the TCS-TLP group at each follow-up visit (P<0.05).Conclusion: Patients treated with two cannulated screws combined one fully threaded cannulated screw with Targon locking plate can have better function improvement, less orthopedic complications and prevent femoral neck shorting.
