                                Subcutaneous emphysema, the underlying cause of crepitus, has been reported in up to 27% of trauma patients with rib fractures and associated pneumothorax. While not universally present, the hallmark crackling or crunching sensation known as crepitus is a key clinical finding that can arise in the context of a pneumothorax.
