Chest wall stabilization and rib fixation using a nitinol screwless system in selected patients after blunt trauma: long-term results in a single-centre experience.

First experiences with rib fixation using nitinol, in terms of reliability and morbidity, influence on pain control and quality of life (QOL), in a large series of selected patients after blunt chest trauma. Data of all patients who had undergone rib fixation by the use of nitinol were retrospectively analysed in terms of indications, morbidity and in-hospital mortality. Pain status and health-related QOL were assessed preoperatively, when possible, at discharge and at 1, 3, 6 and 12 months post-surgery using visual analogous scale and short form 12 questionnaires. From September 2017 to April 2019, 70 patients underwent rib fixation using the nitinol device, of which 47 (67%) had dislocated, painful fractures, 6 (8.5%) had flail chest injuries, 6 (8.5%) were emergencies with haemodynamical instability and 11 (16%) had pseudoarthrosis. Morbidity was 21% without wound infection; in-hospital mortality was 3%. Fracture of the material occurred in 6% of the patients during the first year, but removal of the material was not required. Analysis of the pain score showed a statistically significant decrease in pain for both the whole collective and the group with a series of dislocated and painful fractured ribs (P < 0.001, Tukey contrast on the linear mixed-effects models). Assessment of health-related QOL revealed a significant improvement in the physical score for the mid- and long-term analysis. Our results suggest that rib fixation using the nitinol device is reliable, associated with an acceptable morbidity, while significantly decreasing pain and improving health-related QOL. © The Author(s) 2021.
