Although proximal femoral nail antirotation (PFNA; Synthes, Switzerland) has demonstrated satisfactory results when used for the treatment of intertrochanteric fractures, mechanical complications may occur. To better quantify risk is to treat this study aimed to: (1) characterize frequency and extent blade sliding their correlation with reduction quality (2) identify factors associated complications.A review medical records from 93 patients treated fractures a minimum 6-months follow-up between February 2014 2019 was conducted. Blade position evaluated using Tip-apex distance (TAD) Cleveland index. The adjusted Doppelt's method intramedullary nailing. Individuals were classified as having or not complications, radiologic outcomes compared two groups.Mechanical occurred in 12 94 hips (12.8%), 11 out being group. There no significant difference TAD groups; however, there differences noted index, AO/OTA classification, sliding. mean 1.17 mm (anatomical group), 3.28 (extramedullary 6.11 (intramedullary respectively (P<0.001). Data revealed that an factor (odds ratio 1.25, 95% confidence interval 1.03-1.51).The determined significantly suggesting prevention excessive through proper intraoperative important help achieve outcomes.
