Liu MB, Ali SH, Haonga BT, et al. - In this study, outcomes of distal diaphyseal femur fractures treated with SIGN fin nail vs SIGN standard intramedullary nail were determined. Researchers conducted a prospective cohort study at a single tertiary referral center in Tanzania. Seventy-four (85%) of 85 patients with distal diaphyseal femur fractures treated with either retrograde SIGN Standard Nail or Fin Nail completed the minimum 1-year follow-up. Outcomes associated with the SIGN Fin Nail vs the SIGN Standard Intramedullary Nail at 1 year were comparable. Findings suggest a possible utility of the SIGN Fin Nail as an alternative to Standard locked IM nails for fixation of distal diaphyseal femur fractures.
