Introduction: The aim of the this studyis to compare PFNa application and uncemented bipolar partial prosthesis in AO/OTA 31 A2 type fractures in patients aged >75 years, in terms of functional scores and complication rates, and to then discuss the advantages and disadvantages of the two different methods.

Material and Method:A retrospective examination was made of a total of 132 patients who were operated on because of unstable femoral proximal fracture in 2 different centres between January 2012 and June 2016. 27 patients who selected according to specified criteria in each group were compared in respect of functional scores at the final follow-up examination, complications, hospital length of stay, use of fluoroscopy, time to mobilization, and blood transfusion.

Result: In respect of functional scores, the mean postoperative HHS in groups 1 and 2 were 82.3 and 79.8, respectively (p=0.425), and the pre-postoperative change in KAI in respective order was determined as -0.98 and -1.36 (p=0.114 the length of stay in hospital was found to be statistically significantly shorter in group 1 (p<0.05). The duration of fluoroscopy use was determined to be shorter in group 2.

Conclusion: PFNa usage with applied according to fixation principles can be considered more preferable in these types of fractures. However, in patients with an additional systemic disease, poor bone quality, and where problems may be experienced in fixation, hemiarthroplasty can be considered a good alternative to PFNa.
