Is the number of rib fractures a risk factor for delayed complications? A case-control study.

Aim: To analyse factors that may predict the appearance of rib fracture complications during the first days of evolution and determine whether the number of fractures is related to these complications.

Method: Retrospective case-control study of patients admitted with a diagnosis of rib fractures between 2010 and 2014. Two groups were established depending on the appearance or not of pleuropulmonary complications in the first 72 h, and the following were compared: age, sex, Charlson comorbidity index (CCI), number and uni- or bilateral involvement, mechanism of trauma, days of hospital stay, haemoglobin on discharge minus haemoglobin on admission, pleuropulmonary complications during admission (pneumothorax, haemothorax or pulmonary contusion) and placement of pleural drainage.
