Abstract
Background: Sacrum is the keystone of the pelvic girdle; its fractures are
common in pelvic ring injuries with incidence (30-45%). Longitudinal fractures
of the sacrum were always a matter of controversy both in decision-making for
choice of fixation and approach . Percutaneous and minimally invasive
techniques present perioperative difficulties, but with fewer postoperative
complications compared to open techniques.
Objective: To compare results of both Transilial Internal fixator (TIFI) versus
Iliosacral screw (ISS) regarding; intraoperative and postoperative radiological
and functional outcomes of sacral pelvic fractures fixed in a minimally invasive
percutaneous technique. In addition, assessment of different variables that may
affect outcome and the ideal screw trajectories in the Egyptian population.
Methadology; A Prospective Randomized controlled trial from January 2020
to December 2021was conducted at Cairo university hospital to evaluate the
results of the fixation of sacral fractures using minimally invasive techniques.
The study included 42 patients with complete, comminuted, or bilateral sacral
fractures. Patients were collected in first year and followed up with minimum of
12 months.
Results TIFI technique showed shorter operative time with less need for
intraoperative fluroscopy while ISS technique showed less blood loss and that
was both clinically and statistically significant
