**3. Results**

A total of 387 medical records were analyzed. The Gamma3 nail was used in 262 patients (67.7%) and InterTAN was used in 125 patients (32.3%). The mean age of the study population was 81.6 (SD = 11.3), of which 74.2% were women (Table 1). The patients were followed up with for a median of 1.1 years, with a maximum follow-up of 2.6 years.

A comparison of the sample based on the type of nail revealed that the two groups had similar characteristics, with no significant differences in age, sex, laterality, or mortality. However, there were some variations in the type of fracture observed. In the InterTAN group, 25.6% of the fractures were basicervical, while 7.3% of the Gamma3 nail group had basicervical fractures (*p* < 0.001). Conversely, the Gamma3 nail group had a higher percentage of subtrochanteric fractures (14.1%) compared to the InterTAN group (5.6%; *p* = 0.022). There was no significant difference in the percentage of intertrochanteric fractures between the two groups (*p* = 0.116) (Table 1).

A total of 17 fractures required reoperation, as shown in Table 2. The reoperation rates were higher in InterTAN group compared to the Gamma3 group (*p* = 0.009). Analysis indicates that cut-out may have been a contributing factor to the difference in reoperation rates between the two groups (*p* = 0.016).

Analyzing which other factor could explain the reoperation rate, we can see there was no significant different rate associated with the side of the fracture (*p* = 0.80), sex (*p* = 0.50) or age (*p* = 0.45).
