Geriatric (G60) trauma patients with severe rib fractures: Is muscle sparing minimally invasive thoracotomy rib fixation safe and does it improve post-operative pulmonary function?

Abstract Background Patient outcomes after muscle sparing minimally invasive thoracotomy rib fixation (MSMIT-ORF) in geriatric G60 trauma patients remain poorly studied. This study determined the effect of MSMIT-ORF on pulmonary function (PFT). Non-operatively managed (NOM) patients were also described. Methods Medical records of G60 patients with severe rib fractures with PFTs measured before and after MSMIT-ORF were examined. Patient outcomes (MSMIT-ORF vs NOM) were adjusted in a multivariate logistic regression model. Results 64 patients underwent MSMIT-ORF, 135 were NOM patients. MSMIT-ORF treated patients showed improvements in PFTs on postoperative day 5, p = 0.001. After adjustment analysis, MSMIT-ORF was associated with increased hospital length of stay (OR 44.9; 95% CI, 9.8–205, p  Conclusions MSMIT-ORF is safe and improves pulmonary function in G60 trauma patients diagnosed with severe rib fractures. Future randomized control studies are needed for confirmation.
