Each mechanism produces a characteristic injury pattern, and distinguishing between them matters for both medical management and any legal claim, because the nature, severity, and prognosis of the injury directly determine the damages available. Understanding these injury types — and their long-term functional consequences — is essential for patients, clinicians, and legal professionals navigating the aftermath of a serious collision.
