Title: Percutaneous screws fixation in pelvic and acetabular fractures. Experience in the Traumatology Hospital «Dr. Victorio de la Fuente Narváez»


Introduction: Percutaneous fixation offers advantages in relation to the open reduction in pelvic and acetabulum fractures. The objective of this study is to describe the safety of percutaneous screw surgery in patients with pelvic and acetabulum fractures.
Material and Methods: An observational, retrospective, longitudinal and descriptive study was carried out. The clinical file of adult patients with pelvic and acetabulum fractures with a minor displacement of 3 mm was reviewed, they underwent percutaneous surgery from 2009 to 2018. The mechanism of injury, associated injuries, type of fracture, days of hospital stay, hospital death, trans or postsurgical complications and bone consolidation were studied.
Results: 531 patients were registered, 454 met the inclusion criteria. The average age was 41.7 years, high energy injury had the higher prevalence, 52% of the patients owns an associated lesion, the most frequent in pelvic limbs. The most common fracture was the AO 61B2 type with 38.1%. There was an average of 10.7 days of hospital stay. Fifty patients (3.3%) had some complications, the main one being the bad position of the screws. Two patients suffered hospital death due to associated injuries. All patients presented bone consolidation grade III or IV of the Montoya classification.
Conclusions: Percutaneous surgery in pelvic and acetabulum fractures is a safe surgical procedure since it is associated with low hospital mortality, has a small percentage of complications, decreases hospital stay and has a high rate of bone consolidation. It is a procedure that requires special training and has a long learning curve.
