Nobody reads lawyer websites unless something happened. If you are here, someone was hurt in a crash, a fall, a workplace accident, or an assault. The injury may not have looked serious at first. It may have become serious later. That gap between initial appearance and actual severity is exactly where blunt force trauma cases get complicated.
This page explains how these injuries work medically, why they create specific legal challenges, and what evidence matters most. Morris & Dewett has handled Louisiana catastrophic injury cases for over 25 years. Take your time. Do your research. Reach out when you are ready.
What Is Blunt Force Trauma?
blunt force traumaBlunt force trauma describes injury caused by impact without penetration. The object hits the body, but the skin stays intact. That distinction matters more than it sounds.
With a visible wound, injury severity is obvious at the scene. With blunt trauma, there may be nothing to see. A person struck in the abdomen may walk away from a crash with no external sign of injury and a ruptured spleen. The injury mechanism determines which internal structures are at risk. Compression forces damage solid organs like the liver and spleen. Shear forces tear vascular attachments. Deceleration forces, the kind produced in head-on collisions, create rotational stress that tears brain tissue without any direct blow to the head.
The legal significance of this invisibility is substantial. Insurance adjusters look for visible injury. Emergency physicians work under time pressure. Internal injuries get missed at both stages, and the consequences of that missed diagnosis can be fatal.
Ask any attorney you interview how they handle cases where the initial medical evaluation showed nothing. An attorney without experience in these cases will have no framework for proving injury severity when the first records show the patient was discharged home in stable condition.
Internal Injuries Caused by Blunt Force Trauma
Blunt force trauma produces life-threatening internal injuries that are frequently not visible or detectable at the initial emergency evaluation. The most common share one feature: they can appear stable for hours while internal hemorrhage or organ failure progresses.
A ruptured spleen is the most frequently occurring blunt abdominal injury. The spleen is highly vascular and sits just under the rib cage on the left side. A direct blow or compression from a seatbelt can cause it to tear. Left untreated, splenic hemorrhage is fatal. Treatment often requires emergency splenectomy. A traumatic pneumothorax results when rib fractures or chest compression cause the lung to partially or fully collapse. Flail chest, where three or more ribs fracture in multiple places, disrupts the mechanics of breathing entirely.
blunt abdominal traumaLiver lacerations, bowel perforations, and pancreatic injuries all fall under blunt abdominal trauma. The bowel can perforate from direct impact, spilling intestinal contents into the abdominal cavity. Pancreatic injury from handlebar or steering wheel impact frequently goes undetected on initial CT because enzyme levels take hours to rise. Pelvic fractures carry their own hemorrhage risk because the pelvic ring is surrounded by major blood vessels. A fractured pelvis can cause blood loss of two liters or more before the patient reaches surgery.
Closed-head injuries overlap with brain trauma cases but are worth addressing here because they result from the same blunt mechanism. Acceleration-deceleration in a collision causes the brain to move within the skull. This produces diffuse axonal injury, where nerve fibers are sheared throughout the brain, and can cause subdural hematoma, where blood collects between the brain and its protective covering. Cardiac contusion, bruising of the heart muscle from direct chest impact, creates arrhythmia risk that may not become apparent until 24-72 hours after injury.
Any delay in detecting internal hemorrhage raises mortality. Trauma protocols exist specifically because of this risk.
Ask any attorney you interview whether they have handled cases involving these specific injury types. Ruptured spleen cases, pelvic fracture cases, and cardiac contusion cases each require different medical experts and different sets of medical records. A generalist personal injury attorney may not know what they are missing.
Common Causes of Blunt Force Trauma in Louisiana
Motor vehicle crashes cause the majority of blunt force trauma injuries seen in Louisiana emergency departments. Louisiana recorded 972 traffic fatalities in 2021, including 185 pedestrian deaths and 86 motorcyclist deaths, according to NHTSA data. Pedestrians and cyclists absorb the full force of vehicle impact with no protective structure around them.
cabin intrusionCommercial truck crashes are a distinct category. An 18-wheeler at highway speed generates forces that exceed what any passenger vehicle safety system was designed to handle. Cabin intrusion injuries from underride collisions and broadside impacts are among the most severe blunt force trauma cases. Falls from height on construction sites, scaffolding failures, and machinery crush injuries account for a significant portion of industrial blunt trauma. Louisiana's petrochemical and maritime industries create elevated exposure to these hazard types.
High-speed highway corridors compound the severity. I-20, I-49, and I-10 all cross rural stretches where EMS response times are longer than in urban areas. A person with internal hemorrhage who is 45 minutes from a trauma center has a different prognosis than one who is 10 minutes away. That time gap matters when calculating damages from delayed emergency treatment. Louisiana data from partners for family health shows that 23% of all fatal injuries in 2019 involved traumatic brain injuries, with vehicle crashes as the leading cause.
Assault cases carry both criminal and civil liability. The person who caused the injury can be held accountable in a civil action regardless of whether a criminal case is pursued. The standard of proof differs between criminal and civil proceedings.
When evaluating attorneys for an industrial or workplace blunt trauma case, ask specifically whether they have experience with both OSHA investigations and third-party personal injury claims. The employer liability analysis and the third-party analysis are separate, and missing one means leaving recovery on the table.
Can You Sue for a Blunt Force Injury That Was Not Diagnosed Right Away?
A delayed diagnosis claim is not the same as the personal injury claim against the person who caused the accident. They are separate legal theories that can be pursued simultaneously.
Here is how it works: you are injured in a crash, taken to an emergency department, evaluated, and discharged home. The initial CT showed no obvious injury. Twelve hours later, you return by ambulance with a rigid abdomen and dropping blood pressure. A repeat CT shows a liver laceration that was present on the first scan but read as unremarkable. That is a missed diagnosis. The treating physician had a duty to identify it, breached that duty, and the delay caused you to deteriorate and require a more complicated surgical intervention.
res ipsa loquiturLouisiana courts recognize res ipsa loquitur as a basis for inferring medical negligence when an internal hemorrhage was visible on imaging that a radiologist reviewed and cleared. You do not need a smoking gun when the nature of the error is self-evident from the records.
The key legal issue is the standard of care. Medical malpractice experts compare the initial imaging, vital signs trends, physical exam documentation, and nursing notes against what the standard of care required. If the deviation is clear, the case is viable.
The Louisiana Medical Malpractice Act applies a $500,000 aggregate cap to most malpractice claims, with a separate track for future medical care. This cap is separate from and does not reduce the personal injury damages recoverable from the tortfeasor who caused the accident. The malpractice prescriptive period under La. R.S. 9:5628 is one year from the date the injury was discovered or should have been discovered (with a three-year absolute from the act).
Ask any attorney you consider whether they have handled cases involving both a tortfeasor claim and a concurrent malpractice claim. These cases require coordination between two parallel legal tracks, and an attorney without that experience will miss value in the case.
Diagnostic Testing and Internal Injury Documentation
The standard of care for blunt abdominal trauma requires a CT scan of the abdomen and pelvis. It is the gold standard for detecting solid organ injury, but it is not infallible. CT can miss bowel injuries in the first hours after trauma because intestinal perforation takes time to produce free air or fluid. A negative CT result does not mean there is no injury.
The FAST exam is performed at the bedside within minutes of arrival. It can detect free abdominal fluid quickly, which is a sign of hemorrhage. But its sensitivity is limited. A negative FAST exam in a patient with a ruptured spleen is not uncommon. The standard of care requires follow-up when clinical suspicion remains high.
Serial abdominal exams are required every 2-4 hours for any patient admitted for blunt abdominal trauma observation. This standard exists because injuries evolve. A physician who admits a patient for observation and documents no re-examinations over a 12-hour admission has deviated from standard practice. That deviation appears in the medical records and becomes evidence.
The GCS documented at the scene by EMS and at ED arrival establishes baseline TBI severity. If a patient deteriorates from a GCS of 14 to a GCS of 9 over six hours, that change is documented and provable. Cardiac contusion requires specific diagnostic workup including troponin levels and echocardiography. These tests are not automatically ordered on every chest trauma patient. If a treating physician failed to order them when chest wall injury was present, that gap in care is reviewable.
Louisiana has 13 state-designated trauma centers that contribute data to the LERN Trauma Registry. Major facilities include University Medical Center New Orleans (Level I), Our Lady of the Lake Regional Medical Center in Baton Rouge (Level I), and Willis-Knighton Medical Center in Shreveport (Level II). Trauma center level affects what resources were available when your loved one arrived.
Ask any attorney you consider whether they have worked with a radiologist expert who can testify about what missed imaging findings actually show. An attorney who relies solely on the treating physician's testimony cannot rebut a defense expert who attacks the imaging interpretation.
Evidence That Wins Blunt Force Trauma Cases
The strongest blunt force trauma cases are built from medical records working backward through time. The initial EMS run report documents the mechanism of injury, vital signs at the scene, and the patient's level of consciousness. It is often the most honest description of the injury because it was written before anyone had a legal stake in the outcome.
CT imaging is dated and timestamped. A CT showing liver laceration on Tuesday and a repeat CT showing expansion of that injury on Wednesday is objective evidence of deterioration. Radiology reports that minimize findings become important when a medical expert testifies about what those same images actually show.
Trauma surgery operative notes describe what the surgeon found when the abdomen was opened. Estimated blood loss, organ condition, and operative time translate directly into arguments about injury severity. Insurance company independent medical examiners who claim the injury was minor have to reconcile their opinion with an operative note showing two liters of hemorrhage.
SpoliationPreservation of evidence is time-sensitive. Vehicle ECM data records pre-impact speed and braking. Surveillance footage from intersections and businesses is typically overwritten within 30-90 days. Employer safety records and OSHA incident reports have specific retention schedules. A preservation letter sent the day after an accident creates a legal duty to preserve. One not sent until six months later often finds the evidence gone.
Long-term prognosis documentation requires a life care planner and a vocational expert. The life care planner projects future medical costs based on the treating physicians' recommendations. The vocational expert assesses whether the injured person can return to their prior occupation and at what earning capacity. Both opinions must be supported by medical records and are typically contested by the defense. The question to ask any attorney is whether they have a network of qualified experts in these disciplines and whether those experts have testified in Louisiana courts.
Louisiana Law and Your Claim
Louisiana's Prescriptive Period for personal injury is two years under La. C.C. Art. 3493.11 (effective July 1, 2024). Missing this deadline generally bars the claim entirely, regardless of how serious the injury is.
Louisiana's Comparative Fault threshold changed effective January 1, 2026. Under La. C.C. Art. 2323, if a court finds you 51% or more at fault for the accident that caused your injuries, you recover nothing. Insurance companies build their defense strategy around pushing your fault percentage above that threshold. Accident reconstruction and eyewitness evidence collected early in the case determines whether that strategy succeeds.
Louisiana's tort reform from 2024-2025 changed how economic damages are calculated. Act 423 modified the discovery rule for certain categories of medical expense evidence. Act 519 restricted the collateral source rule for healthcare costs, meaning insurance write-offs and adjustments now affect the provable value of medical bills in some contexts. These changes require that damages calculations be done by attorneys who are current on how Louisiana courts are applying the new rules.
The Direct Action Statute (La. R.S. 22:1269) allows you to sue the at-fault driver's liability insurer directly without first obtaining a judgment against the driver. This matters in cases where the driver has limited assets, is uncooperative, or cannot be located. If the victim dies from blunt force trauma injuries, family members may pursue both a wrongful death claim under La. C.C. Art. 2315.2 and a survival action under La. C.C. Art. 2315.1. These are separate claims with different damage categories and different eligible claimants.
Ask any attorney you consider whether they are current on the 2024-2025 tort reform changes. Specifically, how does Act 519's collateral source rule modification affect how they present medical expense evidence at trial? Attorneys who have not updated their damages presentation strategy since these changes took effect may be presenting damages calculations that are no longer accurate under current Louisiana law.
Recoverable Damages in Blunt Force Trauma Cases
Louisiana blunt force trauma cases typically produce two categories of recoverable damages: economic (medical bills, lost wages, future care costs) and non-economic (pain, suffering, loss of enjoyment of life). Economic damages are documented through medical billing records, lost wage statements, and expert testimony. Emergency surgery, ICU admission, and post-surgical rehabilitation generate substantial documented costs.
Loss of Earning CapacityLost earning capacity is calculated separately from lost wages. Lost wages are what you actually missed while unable to work. Lost earning capacity is the permanent reduction in what you can earn going forward. A 38-year-old construction worker who can no longer do physical labor has a substantial earning capacity loss even if he finds sedentary work at a lower wage.
Non-economic damages (pain, suffering, mental anguish, and loss of enjoyment of life) are not subject to a cap in Louisiana personal injury cases. This is distinct from medical malpractice claims, where the $500,000 cap applies. The amount argued for non-economic damages is built from medical records documenting pain levels, functional limitations, and quality of life changes.
Loss of ConsortiumLoss of consortium is available to a spouse under La. C.C. Art. 2315. It is a separate cause of action, not a subset of the injured person's claim. Future medical care must be projected through a life care planner and converted to present value by a financial expert. Juries are instructed to award the present-day lump sum equivalent of future costs, not a speculative number. That distinction affects how the life care plan is built and presented.
How compensation is ultimately calculated depends on the interplay between documented economic losses, contested non-economic damages, and any comparative fault finding. An attorney handling these cases needs to manage all three tracks simultaneously. Ask any attorney you interview how they handle cases where the defense is contesting both causation and the severity of non-economic damages at the same time.
What to Do After Blunt Force Trauma: Protecting Your Claim
The most damaging thing a person can do after a crash is refuse medical transport and drive home. Internal hemorrhage can present with no symptoms for hours. A person who walks away from an accident scene and then deteriorates at home loses the documented chain of events that connects the crash to the injury.
Accept emergency transport if it is offered. If you leave the scene on your own, go to an emergency department the same day. Document the visit. The connection between the accident and the medical evaluation is established by the date and time of your ED records relative to the police report.
Do not give a recorded statement to the at-fault driver's insurance company before speaking with an attorney. Early recorded statements where you say "I feel okay" or "nothing seems broken" become evidence used to argue that your injuries were minor or arose later from a different cause. You are not obligated to provide a recorded statement before retaining counsel.
Document everything at the scene if you are physically able: photographs of vehicle positions, road conditions, any surveillance cameras visible on nearby buildings, and contact information for witnesses. This documentation is time-sensitive. Photographs from the accident scene taken 20 minutes after impact are far more valuable than photographs taken a week later.
Send or have your attorney send a Preservation Letter immediately. Vehicle ECM data is typically stored on a 30-day rolling basis. Surveillance footage from intersections and businesses is often overwritten in 30-90 days. An employer's safety incident records may be deleted under their normal retention policy. A preservation letter creates a legal duty to retain.
To prevail, a Louisiana plaintiff must prove four elements: duty, breach, causation, and damages. In a blunt force trauma case, duty is typically not contested. Breach is proven through accident reconstruction and witness testimony. Causation is contested through defense medical experts who will argue the injuries are exaggerated or pre-existing. Damages are contested through IME examiners and vocational experts. An attorney handling this case needs a specific plan for each element, not a general approach.
Frequently Asked Questions
- How long do I have to file a blunt force trauma lawsuit in Louisiana?
-
Louisiana's prescriptive period for personal injury is two years from the date of the injury under [La. C.C. Art. 3493.11](https://legis.la.gov/legis/Law.aspx?d=109395) (effective July 1, 2024). If a delayed diagnosis means the full extent of your injury was not known immediately, the prescriptive period may run from the date the injury was or should have been discovered, not the date of the accident. This exception does not extend indefinitely, and courts apply it narrowly.
- Can I sue for blunt force trauma if the injury was not diagnosed right away?
-
Yes. A delayed diagnosis creates two potential claims: the personal injury claim against whoever caused the accident, and a separate medical malpractice claim against the provider who failed to detect the injury. The personal injury claim runs from the date of the accident. The malpractice claim under [La. R.S. 9:5628](https://legis.la.gov/legis/Law.aspx?d=103827) runs one year from the date you discovered or should have discovered the missed diagnosis. Both deadlines require prompt attention.
- What if I was injured at work? Does workers' comp cover blunt force trauma?
-
Louisiana workers' compensation covers medical treatment and a portion of lost wages for work-related injuries. It generally bars a separate lawsuit against your employer. If a third party caused the accident, such as a subcontractor, a delivery driver, or a property owner, you can pursue workers' compensation and a separate personal injury claim against that third party simultaneously. The workers' compensation carrier has a subrogation right and may be reimbursed from your personal injury recovery. An attorney needs to structure the case to account for that reimbursement obligation.
- What does res ipsa loquitur mean in a blunt force trauma case?
-
Res ipsa loquitur means "the thing speaks for itself." In a blunt force trauma context, it applies when the facts so strongly suggest negligence that you can infer it without direct proof. Consider this example: a patient admitted for crash observation suffers a catastrophic internal hemorrhage. The attending team had access to the patient for hours. The hemorrhage was visible on repeat imaging. Those circumstances support a negligence finding without requiring a witness to the specific error. Louisiana courts apply this doctrine in medical malpractice cases when the deviation from standard care is apparent from the record itself.
- How is fault determined when multiple defendants caused the injury?
-
Louisiana applies comparative fault under [La. C.C. Art. 2323](https://legis.la.gov/legis/Law.aspx?d=109387). A jury assigns a percentage of fault to each defendant and to the plaintiff. Each defendant is then liable for their proportionate share of the damages. If the at-fault driver and an employer who owned the vehicle are both defendants, the jury apportions fault between them. If the plaintiff is found partially at fault, their recovery is reduced by that percentage. If the plaintiff is found 51% or more at fault, they recover nothing under the 2026 rule.
- Do I need a trauma surgeon expert to win my case?
-
In most contested blunt force trauma cases, yes. The defense will retain a physician to conduct an independent medical examination and argue that the injuries were minor, pre-existing, or unrelated to the accident. A trauma surgery expert who can review the operative notes, CT imaging sequences, and hospital course and testify to injury severity and causation is essential to counter that defense. The same expert can address whether the initial treating team met the standard of care. Ask any attorney you interview whether they have retained trauma surgery experts in similar cases and whether those experts have testified at trial.
- What should I do immediately after a crash to protect a blunt force trauma claim?
-
Accept emergency medical transport if offered. If you leave the scene without transport, go to an emergency department the same day and document the visit. Do not give a recorded statement to any insurance company before consulting an attorney. Photograph the accident scene, vehicle damage, and any visible injuries before vehicles are moved. Collect contact information from witnesses. Retain an attorney promptly so a preservation letter can be sent to the at-fault driver, their employer, and any property owner before evidence is deleted or overwritten.
- Can blunt force trauma cause permanent disability?
-
Yes. Traumatic brain injury from acceleration-deceleration forces can cause permanent cognitive impairment, personality changes, and motor deficits that do not fully resolve. Spinal cord involvement in high-energy impacts can cause partial or complete paralysis. Major organ injury requiring surgery can result in permanent functional impairment. Pelvic fractures cause chronic pain and mobility limitations in a significant percentage of patients. Whether a specific injury causes permanent disability depends on the injury type, severity, and the course of treatment and rehabilitation. This is documented through treating physician records, neuropsychological testing, and life care planner evaluation.
- How long does a blunt force trauma lawsuit take to resolve in Louisiana?
-
Most contested personal injury cases in Louisiana take 18 months to three years from filing to resolution, depending on court congestion, the complexity of the medical issues, and whether the case goes to trial. Cases involving multiple defendants, delayed diagnosis claims, or disputed causation typically take longer because they involve more discovery and more expert witnesses. Settlement is possible at any point during the case. Cases that reach trial verdict are a small percentage of filed cases. An attorney cannot promise a specific timeline because it depends on factors outside anyone's control, including docket scheduling and the defense's litigation strategy.
