Background: The aim of this study was to evaluate the surgical procedures of osteosynthesis and the respective costs in isolated sternal fractures and manubriosternal dislocations.
Methods: Between January 2006 and July 2011, we treated 47 patients with an isolated fracture and 18 patients with a dislocation of the sternum surgically. In case of sternal fracture, the titanium plate was used in 30 (64%), steel plate in 12 (25%), and steel wire in 5 patients (11%). The stabilization after traumatic luxation was obtained with steel wire in 4 patients (22%) and titanium plate associated with demineralized bone matrix in 14 patients (78%). The quality adjusted life years (QALYs) was analyzed, as well as the incremental cost-effectiveness ratio based on QALYs.
Results: In the sternal fractures, titanium plate showed a decreased time of intervention (30 [2] minutes), length of stay (3 [1] days), and total cost (&OV0556;2,277.10) compared with steel plate (&OV0556;2,667.70) and steel wire (&OV0556;2,801.60) procedures, displaying an excellent difference in QALYs (0.825 and 1.615, respectively). In the sternal dislocation, steel wire technique highlighted a poor QALYs, although this approach was less expensive than titanium plate with demineralized bone matrix (&OV0556;3,553.60 vs. &OV0556;6,047.80). Incremental cost-effectiveness ratio revealed that the titanium plate costs were &OV0556;623.55 more than the steel wire per QALYs gained.
Conclusion: The rigid titanium plate application ensured a safe and easy management of traumatic sternal lesions with a good prognosis of patients, justified by the improved QALYs compared with other methods.
