Introduction/Objective. There are extramedullary and intramedullary methods of trochanteric fractures’ internal fixation with implants having a lag screw. The objective of this study was to examine the difference in impact of these fixation types on final hip function and health-related quality of life. Method. There were 75 patients treated for a trochanteric fracture, using self-dynamisable internal fixator (SIF group), as an extramedullary method, or gamma nail (GN group), as an intramedullary method. These patients were called for the evaluation of Harris Hip Score (HHS) and SF-12 questionnaire at least two years after surgery. The SF-12 questionnaire has dual expression – physical component score (PCS) and mental component score (MCS). Results. There were no significant differences between the SIF group and the GN group regarding HHS, PCS, and MCS. Positive correlation was confirmed between HHS, PCS, and MCS, with the strongest relation between HHS and PCS. Negative correlation was confirmed between age and HHS. Conclusion. There was no difference in final hip function and health-related quality of life between SIF and GN methods in trochanteric fractures treatment (p > 0.05). These parameters of outcome were confirmed to have positive interrelation (p < 0.05). Both submuscular presence of extramedullary implant with dimensions of SIF and the need for bone reaming in cephalomedullary fixation were considered not to have significant impact in HHS and SF-12 scores after trochanteric fractures treatment by internal fixation.
