For the entire cohort, the incidence of postoperative treatment failure (periprosthetic fracture and reoperation) was 29\/326 (8.9%); the IT-treated cohort (7\/162, 4.3%) had a significantly lower rate compared with the PFNA-treated cohort (22\/165, 13.3%). The incidence of postoperative periprosthetic fractures was significantly lower in the IT-treated cohort than in the PFNA-treated cohort (2.5% vs 7.9%).
