A broken breastbone sounds like the whole injury. Research says it is usually the marker for something else.
A sternum fracture travels with other injuries in roughly four out of five cases. Worse, the plain chest X-ray misses most of them. Meanwhile the insurance release on your kitchen table almost certainly covers injuries nobody has found yet.
Below, we explain what the medical literature actually shows. We also cover why Georgia courts rarely undo a signed release, and the narrow situations where they will.
What a Sternum Fracture Usually Means
Motor vehicle collisions cause most of these fractures. Published series put the figure between 60 and 90 percent. Belted occupants in older vehicles without airbags account for much of it.
Two very different injuries hide under the same diagnosis, though. Studies put the isolated share at only 18 to 32 percent.
Outcomes split along that same line. A two-center study of 380 patients recorded zero deaths among isolated sternal fractures. Among those with associated injuries, mortality reached 9.3 percent.
So the diagnosis alone tells you very little. What came with it decides everything.

Here the imaging gap matters enormously. A standard front-to-back chest X-ray detects roughly half of sternal fractures.
Computed tomography changes the picture. One series of 292 patients found 94 percent of sternal fractures visible only on CT, not on conventional radiography.
CT also finds what else is wrong. Reviews report that it detects associated thoracic injuries in more than 80 percent of these patients.
That gap explains a familiar sequence. Someone leaves the emergency department hearing their chest is bruised. Weeks later they learn a bone broke, and that something else did too.
What Travels With a Sternum Fracture
Two associated injuries deserve particular attention, and neither announces itself.
Spinal fractures lead the list. Multiple cohorts, including a nationwide study of 4,765 patients, put them at 36 to 38 percent. The literature calls that pairing sternovertebral injury.
Cardiac injury is the second. Roughly 8 to 11 percent of all sternal fracture patients show blunt cardiac injury, most often myocardial contusion.
One reassuring finding belongs beside that number. Significant cardiac injury is rare where the fracture truly is isolated. A study of 88 such patients found none, and a normal initial ECG with normal troponin largely rules it out.
Rib fractures round it out at about half of cases, with pulmonary contusion, pneumothorax, and hemothorax following.
Why “Surgery and a Long Recovery” Overstates It
Older pages on this subject imply that surgery and a drawn-out recovery come standard. The literature says otherwise, and the honest version is more useful.
Consecutive patient cohorts tell a consistent story. A 13-year study of 262 patients treated 98 percent non-operatively, and a 63-patient series treated all of them without surgery.
Surgery has real indications, but they are narrow. Severe displacement, an unstable or flail sternum, respiratory compromise, intractable pain, or symptomatic nonunion.
Nonunion itself is uncommon. Doctors generally diagnose it when pain and the absence of healing persist past three to six months. Surgery follows only where symptoms demand it.
Healing is ordinary rather than exceptional. Most non-operative fractures heal in roughly six to twelve weeks, though chest pain commonly lasts eight to twelve.
Why a Signed Release Usually Holds in Georgia
This is where the money is won or lost, and Georgia law is unforgiving.
Kennedy v. Bateman, 217 Ga. 458 (1961), states the rule flatly. A release “cannot be avoided merely because the injuries have proved more serious than the releasor believed them to be.”
Read the facts, because they repeat constantly. A woman signed a broad release the day after a wreck, relying on a doctor’s assurance that her injuries were minor. They turned out serious and permanent.
She even returned the money. The Supreme Court of Georgia still enforced the release, because it covered “known and unknown, foreseen and unforeseen” injuries.
Every adjuster’s form contains that language. Parties “may preclude recovery for all injuries, whether known or unknown,” the Court wrote, “if it is their intention” to do so.
The Mistakes Georgia Will Not Fix
Two statutes close the door most people reach for.
Section 23-2-28 handles the obvious theory. “Ignorance of a fact by both parties shall not justify the interference of equity.”
Diligence supplies the second bar. Under § 23-2-29, “if a party, by reasonable diligence, could have had knowledge of the truth, equity shall not grant relief.”
Apply those to a chest injury. An imaging study that would have found the fracture was available, which is precisely the problem.
The Fifteen-Day Rule Nobody Mentions
Georgia does protect hospitalized people, and this provision deserves far more attention than it gets.
Section 51-1-35 bars an adverse party from approaching an injured patient. For 15 days after the injury, nobody may negotiate a settlement, obtain a general release, or take a statement from someone confined to a hospital.
Consequences follow for violations. Any release obtained that way “shall not be admitted as evidence in any court action relating to the injury.”
Pressure after discharge has its own limit. Cravey v. Johnson, 229 Ga. App. 130 (1997), held that an adjuster “may not induce a claimant by trick, artifice or misrepresentations to sign a general release.” That protection applies where a claimant is “under a disability which deprives him of the capacity to read, reason or investigate for himself.”
One procedural requirement surprises people. Rescinding for fraud generally means offering the settlement money back first, under § 13-4-60, promptly after discovering it.
Why Two Years Runs From the Crash
Section 9-3-33 gives two years for a personal injury action. Late diagnosis does not extend it.
Georgia does recognize a discovery rule, yet it is narrow. Courts confine it to bodily injury that “develops over an extended period of time.” That describes toxic exposure, not a collision.
A crash is a discrete event. The clock therefore starts the day it happens, whatever the imaging showed at the time.
What 2025 Changed About Medical Bills
One more development affects what these expenses are worth. O.C.G.A. § 51-12-1.1 took effect .
The measure is now explicit. Medical special damages run to “the reasonable value of medically necessary care, treatment, or services,” as the trier of fact determines it.
Insurance figures entered the conversation too. Where a plaintiff carries coverage, billed charges and the amounts needed to satisfy them both become relevant. Whether the insurance gets used does not matter.
Timing decides which rule applies. The statute reaches causes of action arising on or after that date. A crash from 2024 therefore stays under prior law.
