The impact of proximal femoral nail type on clinical and radiological outcomes in the treatment of intertrochanteric femur fractures: a comparative study.

Abstract

The aim of the study was to compare three different proximal femoral nails in terms of functional and radiological outcomes in patients treated with closed reduction and internal fixation for intertrochanteric femur fractures (IFFs). Between February 2010 and March 2016, 303 consecutive patients (132 male, 171 female) were included in the study. The groups were compared in terms of age, gender, body mass index, duration of surgery and duration of fluoroscopy, blood loss, type of fracture and quality of the reduction, complication rate, and functional and radiological results. Harris hip score (HHS), Barthel index, and full weight bearing time were used for functional evaluation. The quality of the reduction, collodiaphyseal angle (CDA), tip-apex distance (TAD), and fracture union were used for radiological results evaluation. There was no significant difference between groups in terms of fracture type, reduction quality, and complication rates. The mean operation time, duration of scopy, blood loss, and TAD was higher for InterTan, whereas the mean postoperative CDA was higher for PFNA-II. Operation time, postoperative CDA, and full weight bearing duration were higher for Profin than for InterTan. The mean HHS and Barthel Index were higher for PFNA-II, while the mean duration of operation and fluoroscopy, blood loss, TAD, and full weight bearing time were higher for Profin. PFNA-II is a better option than Profin and InterTAN in the treatment of IFFs when the surgical parameters and functional and radiological results were evaluated as a whole.
