Key result
The SIF method for subtrochanteric fractures resulted in significantly shorter operation time (62.2 minutes) and fluoroscopy time (43 seconds) compared to literature data for other fixation methods (p<0.05).
Why the study?
Does the SIF method reduce operation time and fluoroscopy time compared to other internal fixation methods in patients with subtrochanteric fractures?
Observational (n=27)
Does the SIF method reduce operation time and fluoroscopy time compared to other internal fixation methods in patients with subtrochanteric fractures?
p-value: p=<0.05
The SIF method may offer reduced operation and fluoroscopy times compared to traditional internal fixation methods for subtrochanteric fractures.
SIF may shorten operative and fluoroscopy times in subtrochanteric fractures; leaves open comparative efficacy versus standard fixation in larger trials.
Introduction/Objective. Subtrochanteric fractures are unstable, tending to a varus, antecurvatum, and shortening deformity. The aim of this paper was to compare operation time and fluoroscopy time between different internal fixation methods in the treatment of subtrochanteric fractures. Method. The prospective study of the group of 27 patients with a subtrochanteric fracture treated by the SIF (selfdynamisable internal fixator with a trochanteric unit) method had been done. Operation time and fluoroscopy time values from this group were compared to the same parameters data from the literature for intramedullary (IM) nails, proximal femur locking plates (PF-LCP), dynamic condylar screws (DCS), and the 95?-angled blade plate. Results. In the SIF group, operation time was 62.2 (25?140) minutes and fluoroscopy time was 43 (20?95) s. Average operation time from the literature data was: 102.1 (43?181) minutes for IM nail, 94.2 (75?129) minutes for PF-LCP, 105.3 (70?166) minutes for DCS and 221.5 (171?272) minutes for blade plate. Average fluoroscopy time from the literature data was: 109.6 (34?250) seconds for IM nail, 102.3 (47?180) seconds for PF-LCP, 238 seconds for DCS. Operation time and intraoperative fluoroscopy time were higher in IM nail, PF-LCP, DCS and blade plate comparing to SIF method (p < 0.05). Conclusion. The above mentioned difference could be explained by a degree of required accuracy in the initial operative technique maneuvers, by used number of screws and by the type of the fracture reduction performance in different fixation methods. Operation time during IM nailing of subtrochanteric fractures sometimes can be shorter than average operation time in SIF method, what could be explained by the skill of the surgeon to perform as fast closed reduction for insertion of guide wire.

Mitković et al. (2018) conducted an observational in Subtrochanteric fractures (n=27). SIF (selfdynamisable internal fixator with a trochanteric unit) method vs. Literature data for intramedullary (IM) nails, proximal femur locking plates (PF-LCP), dynamic condylar screws (DCS), and 95-degree angled blade plates was evaluated on Operation time (p=<0.05). The SIF method for subtrochanteric fractures resulted in significantly shorter operation time (62.2 minutes) and fluoroscopy time (43 seconds) compared to literature data for other fixation methods (p<0.05).
