20.500.12556/RUL-154725 Surgeon-stratified periprosthetic fracture risk in a single-hospital cohort of 1531 uncemented ABG-II femoral stems at primary total hip arthroplasty Purpose Late periprosthetic fracture risk with uncemented ABG-II femoral stems at primary total hip arthroplasty (THA) has been reported before, but single-hospital surgeon-stratified reports of this implant have never been published. We asked whether periprosthetic fracture rates of ABG-II femoral stems implanted at a single tertiary hospital depended on patients’ age, gender and the operating surgeon. Methods The study included 1531 consecutive primary ABG-II femoral stems implanted at a single tertiary hospital between January 1, 2012 and December 31, 2018. The Kaplan–Meier and Cox regression analyses were performed after 3.6–10.6 years of follow-up. Results In the cohort, we recorded 8 intraoperative, 22 early postoperative (within 90 days of implantation) and 26 late periprosthetic fractures (over 90 days postoperatively). The revision rate of ABG-II femoral stems was 5.1/100 component-years for early and 0.3/100 component-years for late periprosthetic fractures. The Kaplan–Meier cumulative probability of periprosthetic fracture was 2.1% at one, 2.3% at 2, 3.2% at 5, and 6.5% at 10 years after the implantation. Higher patient's age at operation was an independent risk factor of subsequent periprosthetic fracture (hazard ratio 1.07, 95% confidence interval 1.03–1.10; p < 0.01), regardless of the operating surgeon. Most of the fractured femora were Dorr type C (stovepipe). Conclusion The study presents the largest published ABG-II femoral stem cohort from a single hospital so far with 9291 component-years of observation. Periprosthetic fracture risk of ABG-II increased with patients’ age, had no variability between different surgeons, and was considerably higher from other uncemented femoral stems used at the same hospital. total hip arthroplasty periprosthetic fracture cohort analysis surgeon stratification true false true Angleški jezik Ni določen Članek v reviji 2024-02-26 09:34:01 2024-02-26 09:34:03 2024-02-27 03:42:07 0000-00-00 00:00:00 2023 0 0 Str. 1850-1857 iss. 11 Vol. 57 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 616.7 1998-3727 10.1007/s43465-023-00996-2 186240771 s43465-023-00996-2.pdf s43465-023-00996-2.pdf 1 717319F343E45C65BF98DC5262EAA3B3 8004e8134b9aedbd7f35bd9a9c97bf8863e2370c016c083abda24e5970a9a213 0d1d2743-d482-11ee-b5a4-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181263 https://link.springer.com/article/10.1007/s43465-023-00996-2 0 f52d2c05-d481-11ee-b5a4-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181262 Medicinska fakulteta 0 0 0
