Should nails be locked dynamically or statically in atypical femoral fractures? - A radiological analysis of time to union and reoperations in 236 displaced fractures with 4 years average follow-up.

Introduction: Atypical femoral fractures (AFFs) are associated with delayed union and higher reoperation rates. Axial dynamization of intramedullary nails is hypothesized to reduce time-to-union (TTU) and fixation failure as compared to static locking.

Methods: Consecutive acutely displaced AFFs fixed with long intramedullary nails across five centres between 2006 and 2021 with a minimum postoperative follow-up of three months were retrospectively reviewed.

Three-dimensional navigation-guided percutaneous screw fixation for nondisplaced and displaced pelvi-acetabular fractures in a major trauma centre.

Background: Navigation assisted minimally invasive percutaneous screw fixation (MIS) for pelvi-acetabular fracture was recently advocated.

Methods: We report 38 consecutive cases of pelvi-acetabular fractures treated with 3D navigation-guided MIS from 2015 to 2016. Ohe hundred and forty-three screws were inserted (59 sacroiliac, 45 retrograde anterior column, 34 supra-acetabular, three antegrade posterior-column and two subcristal).

Standardised multidisciplinary protocol for haemodynamically unstable pelvic fractures.

Purpose: To review treatment results of 29 patients with haemodynamically unstable pelvic fractures after implementation of a standardised multidisciplinary protocol.

Methods: Records of 14 men and 15 women aged 14 to 84 (mean, 46) years who were treated for haemodynamically unstable closed (n=27) or open (n=2) pelvic fractures were reviewed. The survival rates before and after implementation of a standardised protocol were compared.
