Internal Injuries

What Are Internal Injuries From a Car Accident?

Internal injuries are damage to organs, blood vessels, or tissues beneath the skin that often don’t produce visible wounds. In Houston car wrecks, they typically result from three forces: blunt-force trauma (chest hitting the steering wheel or airbag), deceleration trauma (organs continuing to move when the body suddenly stops), and penetrating trauma (broken glass, metal, or a fractured rib piercing tissue). Each can rupture an organ, cause internal bleeding, or collapse a lung — sometimes hours after you walk away from the scene.

Because the damage is hidden, victims often feel “fine” at the scene and decline an ambulance. Adrenaline, shock, and inflammation can mask symptoms until pressure builds, blood loss accumulates, or a punctured lung worsens. By the time the ER becomes obvious, the case can already be harder to prove — which is exactly why insurance adjusters push for quick statements before medical imaging is complete.

Common Internal Injuries After a Houston Car Crash

Our firm handles claims involving every category of internal trauma documented in modern emergency medicine. The following are the injuries we most often see after Houston collisions:

1. Internal Bleeding (Hemorrhage)

Torn or crushed blood vessels release blood into the abdomen, chest, or pelvis. Hemorrhagic shock can occur within minutes if a major vessel is involved. Warning signs include dizziness, rapid heart rate, pale or clammy skin, severe abdominal pain, and fainting.

2. Ruptured Spleen, Liver, or Kidney Damage

The spleen and liver are the most frequently injured solid organs in motor vehicle collisions. A lap-belt or steering-wheel impact can lacerate or rupture either, triggering massive internal bleeding. Kidney trauma can cause blood in the urine, flank pain, and long-term renal complications.

3. Pneumothorax (Collapsed Lung) and Hemothorax

Rib fractures from a seatbelt, airbag, or steering wheel can puncture a lung, allowing air or blood into the chest cavity. Symptoms include sharp chest pain, shortness of breath, and rapid breathing. Pneumothorax is a medical emergency requiring chest tube placement.

4. Abdominal Aortic Injury and Aortic Dissection

High-speed deceleration — common in head-on and T-bone crashes — can tear the aorta, the body’s largest artery. Aortic injuries are among the leading causes of immediate death in motor vehicle collisions and require emergency surgical repair.

5. Bowel, Mesenteric, and Pancreatic Trauma

Compression across the abdomen — typically from a seatbelt — can tear the small intestine or its supporting mesentery. Untreated, this leads to peritonitis, sepsis, and shock. Pancreatic injuries are easy to miss on first imaging and often surface days later.

6. Cardiac Contusion and Diaphragm Rupture

A bruised heart muscle (cardiac contusion) can cause arrhythmias for weeks after a crash. Diaphragm tears allow abdominal organs to push into the chest, compromising breathing — a frequently missed injury on initial CT scans.

7. Traumatic Brain Injury (TBI) and Skull Fractures

Bleeding inside the skull — subdural or epidural hematoma — is technically an internal injury and is frequently delayed. If you or a loved one suffered a concussion, loss of consciousness, or post-crash confusion, our Houston traumatic brain injury attorneys understand the imaging, neuropsychological testing, and long-term care projections these cases demand.

8. Spinal Cord and Internal Disc Injuries

Herniated discs, spinal hematomas, and cord injuries can compress nerves and cause permanent neurological deficits. These overlap with our work on Houston spinal cord injury claims and require lifetime care valuations.

Delayed Internal Injury Symptoms You Should Never Ignore

Symptoms of internal trauma can emerge hours, days, or even weeks after a crash. Seek emergency care if you notice any of the following after a Houston car accident:

• Persistent or worsening abdominal pain, tenderness, or swelling
• Deep purple bruising across the chest, abdomen, or shoulder (especially “seatbelt sign”)
• Shortness of breath, sharp chest pain, or pain when breathing deeply
• Dizziness, lightheadedness, fainting, or unusually rapid heart rate
• Blood in vomit, urine, or stool — or unusually dark stool
• Severe headache, confusion, slurred speech, or memory problems
• Pain radiating to the shoulder (a classic sign of splenic rupture)
• Numbness, tingling, or weakness in the limbs

If any of these appear, call 911 or get to a Houston emergency room — Memorial Hermann–TMC, Ben Taub, Houston Methodist, or any Level I Trauma Center — before you speak to any insurance adjuster.

Why Internal Injury Claims Are Harder to Win in Texas

Internal injuries pay out higher than soft-tissue claims — and insurers know it. They use specific tactics to reduce or deny these claims:

• Delayed-treatment defense. If you didn’t go to the ER the same day, the carrier argues your injury wasn’t caused by the crash.
• Pre-existing condition argument. They claim a prior fatty liver, hernia, or back issue caused your damage — not the wreck.
• Causation challenges. They demand a treating physician explicitly link each injury to the collision in writing.
• Comparative fault under Tex. Civ. Prac. & Rem. Code § 33.001. If you’re found 51% or more at fault, you recover nothing. Below that, your award is reduced by your fault percentage.
• Lowball early offers. Carriers offer a quick settlement before the full extent of organ damage, surgery costs, or future care is known.

Texas is a modified comparative negligence state. Under Tex. Civ. Prac. & Rem. Code § 33.001, a single percentage point of fault assigned to you can wipe out your recovery if it pushes you to the 51% bar. Insurers exploit this aggressively in internal injury cases by attacking causation, medical history, and post-crash conduct.

Houston Crash Scenarios That Commonly Cause Internal Trauma

Some collisions are far more likely to produce hidden injuries than others. We routinely investigate internal injuries in cases involving:

• T-bone and side-impact crashes — limited side protection leads to rib fractures, splenic rupture, and pelvic injuries.
• Head-on collisions — extreme deceleration tears the aorta, mesentery, and diaphragm.
• Rollover accidents — multidirectional forces produce compound organ injuries and TBIs.
• Houston 18-wheeler and truck crashes — large weight differentials cause crush injuries to chest and abdomen.
• Motorcycle accidents — direct impacts to the torso commonly cause organ rupture and pneumothorax.
• Uber, Lyft, and rideshare collisions — multiple coverage layers complicate medical-bill reimbursement.

Speeding, distracted driving, and intersection negligence are among the most frequent common causes of Houston car crashes we see in internal injury files.

The Medical Evidence That Wins Internal Injury Cases

Strong internal-injury claims are built on objective imaging and physician testimony — not victim self-report. We work with treating doctors and retained experts to assemble:

• FAST (Focused Assessment with Sonography for Trauma) exam results from the ER
• CT scans with IV contrast showing organ lacerations, free fluid, or hematoma
• Chest X-rays and CT angiograms identifying pneumothorax, hemothorax, or aortic injury
• Operative reports from any emergency surgery, splenectomy, or chest tube placement
• Lab work showing blood loss markers (hemoglobin drop, elevated lactate)
• Follow-up imaging documenting healing or permanent damage
• Life-care plans and economist reports for catastrophic or permanent injuries

We preserve every piece of this evidence early — before records are lost, recall fades, or insurers question the chain of causation.

Compensation Available for Houston Internal Injury Victims

Texas law allows victims of a negligent driver to recover both economic and non-economic damages. In internal injury cases, those typically include:

Economic Damages

• Emergency room, hospital, surgical, and ICU costs
• Future medical care, rehabilitation, and follow-up imaging
• Prescription medications and medical devices
• Lost wages, lost earning capacity, and diminished work life
• Home and vehicle modifications for permanent disability
• Property damage to your vehicle

Non-Economic Damages

• Physical pain and suffering
• Mental anguish, anxiety, and post-traumatic stress
• Loss of enjoyment of life and physical impairment
• Disfigurement and scarring from surgery
• Loss of consortium for spouses

In cases involving gross negligence — drunk drivers, fleeing motorists, or commercial carriers that violated federal safety rules — Texas also allows exemplary (punitive) damages under Chapter 41 of the Civil Practice & Remedies Code. When a loved one dies from internal injuries, families may also pursue a Houston wrongful death claim alongside a survival action.

How Our Houston Internal Injury Claim Process Works

Step 1 — Free Case Review (Same Day)

We listen, review your crash report and medical records, and explain your legal options at no charge. We come to your hospital room or home if needed.

Step 2 — Investigation and Evidence Preservation

We obtain the Texas Peace Officer’s Crash Report (CR-3), 911 audio, traffic camera footage, ECM/black box data, and witness statements before they disappear.

Step 3 — Medical Coordination

We help you get treatment — often on a letter of protection so you owe nothing out of pocket — and coordinate with specialists who can document the full extent of your internal injuries.

Step 4 — Demand and Negotiation

Once you reach maximum medical improvement, we issue a comprehensive demand backed by imaging, expert opinions, and a damages model that reflects future care.

Step 5 — Litigation If Needed

If the insurer refuses fair value, we file suit in Harris County district court and prepare your case for trial. Most cases settle, but adjusters pay more when they know your lawyer will try the case.

Texas Statute of Limitations for Internal Injury Claims

Under Tex. Civ. Prac. & Rem. Code § 16.003, you generally have two years from the date of the crash to file a personal injury lawsuit in Texas. Missing this deadline almost always ends the claim — no matter how strong the evidence.

Important exceptions and shorter deadlines can apply:

• Wrongful death actions: two years from the date of death (Tex. Civ. Prac. & Rem. Code § 16.003(b))
• Claims against a City of Houston vehicle or municipal property: written notice required within 90 days under the city charter
• Claims against the State of Texas or other governmental units: 6-month notice under the Texas Tort Claims Act
• Minor victims: tolled until the minor turns 18 (Tex. Civ. Prac. & Rem. Code § 16.001)
• Discovery rule: limited application when an injury could not reasonably have been discovered earlier

Because internal injuries are often diagnosed late, do not assume you have time. Call us as soon as you suspect a hidden injury.
