Broken Sternum Car Accident Settlement: What Shapes the Value of These Claims

A broken sternum — the flat bone running down the center of your chest — is one of the more painful and disruptive injuries that can result from a car accident. It's also one that tends to generate serious insurance claims. Understanding how these settlements generally work, and what factors push values higher or lower, helps set realistic expectations for anyone moving through this process.

What a Sternal Fracture Means for a Claim

The sternum sits directly behind where a seatbelt crosses your chest. In a moderate to severe collision, that restraint force — or impact with a steering wheel or airbag — can fracture the bone. The injury is almost exclusively associated with significant trauma, which means it rarely occurs without accompanying documentation: emergency room visits, imaging, and often extended recovery periods.

That documentation matters enormously in a personal injury claim. Insurers evaluate claims based on evidence, and a broken sternum typically generates a clear medical record trail — X-rays, CT scans, hospitalization notes, follow-up care, and sometimes referrals to orthopedic or cardiothoracic specialists. The more thoroughly the injury is documented, the more clearly damages can be calculated.

What Damages Are Typically Included

Personal injury settlements generally aim to compensate for two broad categories of harm:

Economic damages — losses with a measurable dollar value:

• Emergency room costs
• Imaging and diagnostic testing
• Hospitalization (sternal fractures sometimes require inpatient care, particularly when complications arise)
• Follow-up physician visits and specialist care
• Physical therapy or rehabilitation
• Lost wages during recovery
• Future medical costs if ongoing treatment is expected

Non-economic damages — losses that don't come with a receipt:

• Pain and suffering
• Loss of enjoyment of life
• Emotional distress
• Loss of consortium (a spouse's claim for impact on the relationship)

A sternal fracture is a high-pain injury with a recovery period that typically runs weeks to months. During that time, normal activities — sleeping, breathing deeply, reaching overhead, driving — are often significantly limited. Those functional limitations tend to weigh heavily when non-economic damages are evaluated.

Key Variables That Shape Settlement Amounts

No reliable "average" exists for broken sternum settlements because the range is genuinely wide. Several factors consistently influence where a specific claim lands:

Fault Rules and State Law Matter Significantly 🏛️

How much of an at-fault driver's liability you can recover depends heavily on which state the accident occurred in and what fault rules apply.

• Pure comparative fault states allow recovery even if you were partially at fault — your compensation is reduced by your percentage of fault.
• Modified comparative fault states bar recovery once your fault reaches a threshold (typically 50% or 51%).
• Contributory negligence states (a small minority) can bar recovery entirely if you were even slightly at fault.
• No-fault states require injured parties to turn first to their own Personal Injury Protection (PIP) coverage before pursuing the at-fault driver — and may limit the ability to file a lawsuit unless injuries meet a defined threshold.

The difference between these frameworks isn't marginal. A sternal fracture claim worth $80,000 in one state might be treated very differently in another based solely on how fault is allocated and what insurance systems apply.

Insurance Coverage Layers That Affect Recovery

A settlement is only as large as the coverage available to pay it. The at-fault driver's bodily injury liability coverage is the primary source of compensation in a third-party claim — but policy limits vary widely. A driver carrying only state minimum liability coverage may not have enough to fully compensate a serious chest injury.

If that gap exists, your own underinsured motorist (UIM) coverage may step in to cover the difference, up to your policy limits. MedPay or PIP can help cover immediate medical bills regardless of fault. Understanding which coverages apply in your situation is a threshold question in any claim.

How Settlements Are Calculated and Negotiated

Insurers typically begin by reviewing medical records, treatment costs, and any lost wage documentation. Adjusters use that information — along with internal guidelines, liability assessments, and sometimes proprietary software — to generate an initial offer.

In represented cases, attorneys typically send a demand letter that outlines damages, supporting evidence, and a settlement figure. Negotiation follows. The process can take months, particularly if treatment is still ongoing. Settling before reaching maximum medical improvement (MMI) — the point at which your condition has stabilized — can undervalue future care needs. ⚠️

What the Numbers Don't Capture

Sternum fracture settlements have been reported across a broad spectrum — from claims settling in the low five figures for straightforward fractures with limited complications, to six-figure outcomes involving surgery, cardiac involvement, lengthy recovery, and significant lost income. Those figures are not benchmarks. They reflect specific facts, specific states, specific insurance situations, and specific negotiation outcomes.

The variables that actually determine where your claim falls — your state's fault rules, the coverage available, your documented losses, how your injury affected your daily life, and how the claim is handled — aren't captured in any general figure. That's what makes case-specific information the only information that actually matters here.
