Comparison of the Effectiveness of Surgical Versus Nonsurgical Treatment for Multiple Rib Fractures Accompanied with Pulmonary Contusion.

Objective: To compare the effectiveness of surgical versus nonsurgical treatment for multiple rib fractures accompanied with pulmonary contusion.

Methods: The clinical records of consecutive 167 patients with multiple rib fractures accompanied with pulmonary contusion, who were treated from June 2014 to June 2017, were retrospectively analyzed. Of them, 75 and 92 underwent surgery (surgery group) and non-surgical treatment (non-surgery group), respectively.
