Incentive SpirometrySecondary· Inpatient: occurred daily at 10 AM while the patient was hospitalized. Post-discharge: occurred at outpatient clinic follow-up encounter that occurred at 2, 4, and 8 weeks post discharge.
The maximum volume (ml) of inspired air through a handheld device called an incentive spirometer. Best value of 3 attempts is recorded. The value of the inspired volume is normalized for patients age, sex, and height and in measured in the percent predicted for that particular individual.

Adverse events — posted to ClinicalTrials.gov
Time frame: 2 months after study participant was discharged from index admission..
Reporting threshold: 1%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
This study evaluates the efficacy of surgical stabilization of rib fractures, as compared to best medical management, for patients with multiple, displaced rib fractures.
Half of patients will be randomized to surgery (in addition to best medical management), whereas the other half will be randomized to medical therapy only.
The primary outcome will be the subjects overall quality of life measured at two months following injury.
