Analysis of complications resulting from femoral neck fracture treatment using Targon FN system

Abstract

The study was aimed to assess the outcomes of the operative procedure applied in the patients with the femoral neck fracture, treated with the Targon FN system, manufactured by Aesculap, and identify relationships between the outcome of treatment of the femoral neck fracture, patient’s body mass, length of the period between the moment of injury and surgery, age of patient, prescribed medications. Study criteria were met by 19 patients aged between 25 and 87 and the average follow-up time was 20 months. Over the period between the surgery time and the study time, 3 patients died. The diagnosed complications included fracture below the implant (plate), aseptic necrosis of the femoral head, pseudarthrosis of the femoral neck and deep vein thrombosis. The joint functionality was assessed using the Harris Hip Score, where excellent and good results accounted for 70 per cent of all results. Given the low-invasiveness of the surgery, this is a recommendable method that allows for the preservation of the patient’s hip joint, early rehabilitation and bringing patient to the vertical position. Complications were primarily diagnosed in the patients who had a postponed surgery, i.e. over 4 days after the injury involving 31B3 fracture according to AO.
