Car Accident Pelvis Fractures

If you or someone in your family has a pelvic fracture after a Kentucky crash, you are reading this from the worst week of your life. The page below is meant to do two things: explain in plain English what a pelvic fracture actually is, and lay out exactly what an injured person and their family should be doing while the medical team works. We have built our practice around motor vehicle crash cases, and pelvic ring injuries are some of the most consequential ones we handle. Call (502) 888-8888 any hour. The line is staffed.

How Common Pelvic Fractures Are in Kentucky Crashes

Pelvic fractures account for roughly 3 percent of all skeletal fractures, but they are heavily concentrated in motor vehicle trauma. According to StatPearls (NIH National Library of Medicine), motor vehicle collisions and motorcycle crashes are responsible for the majority of high-energy pelvic ring disruptions. The CDC injury data consistently shows that road traffic crashes are a leading cause of severe pelvic trauma in adults under 65.

The mortality rate for unstable pelvic fractures with hemodynamic instability has historically run between 15 and 50 percent in older studies, and modern damage-control protocols have brought that down significantly, but it is still high enough that any unstable pelvic fracture is treated as a true emergency. Peer-reviewed pelvic ring research shows that early stabilization and access to a Level I trauma center are two of the strongest predictors of survival and long-term function.

Anatomy of the Pelvic Ring

The pelvis is a closed ring made up of three paired bones (the ilium, the ischium, and the pubis) plus the sacrum and coccyx in the back. The two halves of the ring meet in the front at the pubic symphysis and in the back at the sacroiliac joints. Inside the ring sit the bladder, the rectum, the lumbosacral nerve plexus, and the iliac arteries and veins. On the outside, each side cradles the femoral head in a deep socket called the acetabulum. That is why a pelvic fracture so often means trouble for the hip too. We cover hip-side injuries on our hip injuries page.

Because the pelvis is a ring, breaks usually happen in pairs. If one part of the ring fails, the structure cannot hold its shape and a second break or joint disruption shows up somewhere else. Surgeons call this a ring rule, and it is why an x-ray that shows a single pubic ramus fracture still gets a CT scan. The hidden injury, on the back of the ring, is often the dangerous one.

Types of Pelvic Fractures Caused by Car Accidents

Trauma surgeons use two main classification systems. The Tile system focuses on stability of the ring. The Young-Burgess system focuses on the direction the force came from. Both are described in detail by the American Academy of Orthopaedic Surgeons (OrthoInfo).

Tile Classification (A, B, C)

• Tile A. Stable ring. Often a single pubic ramus fracture or an avulsion from a low-energy event. The ring still holds its shape. These can usually be managed without surgery.
• Tile B. Rotationally unstable, vertically stable. Open-book and lateral-compression patterns. The two halves of the ring can hinge apart but are still held together vertically.
• Tile C. Rotationally and vertically unstable. The most severe. Both rotation and vertical shear are present. These almost always require surgical fixation.

Young-Burgess Classification

• Lateral Compression (LC). Side-impact (T-bone) crashes. Force from the side pushes one half of the ring inward. Common in driver-side or passenger-side strikes. Subdivided into LC-I, LC-II, and LC-III based on severity.
• Anteroposterior Compression (APC). Front or rear impact. Force from front to back drives the ring open like a book. APC-II and APC-III injuries usually mean significant ligament damage and a high bleeding risk.
• Vertical Shear (VS). A fall or downward axial load, or being ejected from a vehicle. One half of the ring is forced upward. Usually unstable and surgical.
• Combined Mechanical (CM). Mixed forces from a complex impact. Often the rollover or the multi-vehicle pileup. Treatment depends on the dominant pattern.

Acetabular Fractures

An acetabular fracture is a break in the hip socket itself. It is technically a pelvic fracture but the surgical approach is closer to a hip reconstruction. These often happen in dashboard-impact crashes where the femur is driven backward into the socket. AAOS OrthoInfo on acetabular fractures covers the surgical approaches in detail. We pair these cases with the medical record review on our hip injuries page and our upper-leg injuries page.

Sacral Fractures and Insufficiency Fractures

The sacrum is the back of the ring. A sacral fracture often involves the sacral nerve roots that supply the bladder, the bowel, and sexual function. Older adults can sustain sacral insufficiency fractures from a relatively low-speed crash because of pre-existing osteoporosis. The lumbosacral plexus runs right through this area, which is why a sacral fracture sometimes looks more like a back-and-leg injury than a pelvic one. We cover the lumbar piece on our lumbar spine injuries page.

Symptoms of a Pelvic Fracture After a Crash

Some pelvic fractures are obvious from the second the wreck stops moving. Others hide. A bruise across the lower abdomen, a slight rotation of one leg, or a single line of pain when the EMT presses on the iliac crests can be the only sign of a serious break. Below are the symptoms our clients describe most often when they look back on the day of the crash.

The First 60 Minutes After the Crash

Every pelvic fracture protocol in a Kentucky Level I trauma center is built around the first hour. Internal bleeding is the threat. Surgeons stabilize the ring, look for the bleed, and stop it. Below is what usually happens at UofL Health (Louisville) and the UK HealthCare Albert B. Chandler Hospital (Lexington), both of which are verified Level I trauma centers.

1. Pelvic Binder AppliedA circumferential sheet or commercial binder is placed at the level of the greater trochanters within minutes of arrival. This closes an open-book pelvis and tamponades venous bleeding. The binder is the single most time-sensitive intervention.
2. Resuscitation and Trauma WorkupTwo large-bore IVs, type and crossmatch, and a balanced massive transfusion protocol if blood pressure is dropping. FAST ultrasound checks for free fluid in the abdomen.
3. CT Pelvis with ContrastOnce stable enough, a CT scan with IV contrast maps the fracture pattern and looks for active arterial bleeding. A “blush” on CT means a bleed that needs angiography.
4. Angiography or Preperitoneal PackingActive arterial bleeding goes to interventional radiology for embolization. Persistent venous bleeding sometimes goes to the OR for preperitoneal pelvic packing. Either way, the goal is to stop the bleed.
5. External Fixation or Definitive SurgeryAn external fixator may be applied as a temporary measure. Definitive open reduction and internal fixation usually happens in the next several days once the patient is stable.

Diagnosis and Imaging

Pelvic ring injuries are diagnosed by physical exam and imaging in tandem. A trauma surgeon palpates the iliac crests for instability, looks at leg position and length, and checks pulses, sensation, and motor function in both legs. Then imaging confirms the pattern.

• Plain x-ray (AP pelvis). The first image. Used in the trauma bay to identify obvious displacement and ring disruption.
• CT pelvis with contrast. The standard of care for any high-energy pelvic injury. CT shows the fracture lines, the sacroiliac joints, the acetabulum, and any active bleeding.
• CT angiography. Adds vascular detail when an arterial bleed is suspected.
• Inlet and outlet pelvic views. Dedicated x-ray angles used by orthopedic surgeons during pre-operative planning to see the ring at different perspectives.
• MRI. Used later to evaluate sacral nerve injury, occult fractures, and labral or cartilage damage when an acetabular fracture is involved.

The radiology read on the day of the crash sets the legal timeline as much as the clinical one. The first CT report is the document that locks the pattern in. We get certified copies of the original images, not just the report, because a follow-up read months later sometimes finds an injury that was missed at intake.

Treatment Options for a Pelvic Fracture

Treatment depends on the Tile and Young-Burgess pattern, the patient’s overall condition, and any associated injuries. Pelvic fractures rarely show up alone in motor vehicle trauma. The patient often has a head injury, a chest injury, a long-bone fracture, or some combination. The orthopedic plan is built around the trauma plan.

Non-Surgical Management

Stable pelvic fractures, including most Tile A patterns and isolated pubic ramus fractures, are usually treated without surgery. The protocol is rest, weight-bearing restrictions for 6 to 12 weeks, pain control, and physical therapy. The patient typically uses a walker or crutches and progresses to full weight bearing once the pain allows. Even non-surgical pelvic fractures need follow-up x-rays at 2, 6, and 12 weeks to confirm the ring is healing in place.

External Fixation

An external fixator is a metal frame attached to the pelvis with pins through the iliac crests. It is often placed in the trauma bay or the OR as a temporary stabilizer. It controls bleeding, restores the shape of the ring, and buys time. Some Tile B injuries are treated with external fixation as the definitive solution. More often it is a bridge to internal fixation once the patient is stable.

Open Reduction and Internal Fixation (ORIF)

The standard surgical treatment for unstable pelvic fractures. The surgeon opens the area, lines up the bones anatomically, and secures them with plates and screws. The anterior ring is typically fixed with a plate over the pubic symphysis. The posterior ring is fixed with iliosacral screws or a plate across the sacroiliac joint. The surgery can run several hours and often requires both an orthopedic trauma team and a general trauma surgeon.

Percutaneous Iliosacral Screws

A minimally invasive technique for posterior ring injuries. The surgeon uses fluoroscopy to place long screws across the sacroiliac joint through small skin incisions. Less blood loss than open ORIF, but technically demanding. Used selectively in Tile B and C patterns.

INFIX (Subcutaneous Internal Fixator)

A newer alternative to external fixation that places the bar under the skin instead of outside the body. Reduces pin-site infection risk and is more comfortable during the recovery period. Typically used for anterior ring injuries that need stabilization but not full ORIF.

Acetabular Reconstruction

Fractures into the hip socket usually require their own surgery. The surgical approach depends on the column or wall involved. Recovery is slower than a typical pelvic ring fixation because the joint surface has to heal smoothly to avoid post-traumatic arthritis. Some patients eventually need a total hip replacement years later.

Pelvic Fracture Recovery Timeline

Below is the typical recovery arc we see in our Kentucky pelvic-fracture clients. Every case is different; this is a working baseline, not a guarantee.

Long-Term Complications We See in Pelvic Fracture Cases

The visible recovery is the bones healing. The invisible recovery is everything else. Roughly half of severe pelvic fracture patients report at least one ongoing problem two years out, according to the peer-reviewed pelvic ring outcomes literature. We document each of the following when they apply.

• Chronic Pelvic and Low Back Pain. The most common long-term complaint. Often worse with prolonged sitting, standing, or driving.
• Post-Traumatic Arthritis of the Hip. Especially common after acetabular fractures. Can lead to a future total hip replacement.
• Sexual Dysfunction. Erectile dysfunction in men and dyspareunia in women are documented complications of pelvic and sacral injury, often through nerve disruption.
• Urological Problems. Bladder dysfunction, urethral stricture after urethral injury, and incontinence.
• Sacral Nerve Injury. Numbness, weakness, and bowel-bladder issues from L5 to S4 nerve root involvement.
• Malunion and Nonunion. When the ring heals in the wrong position or fails to heal at all, requiring a revision surgery.
• Heterotopic Ossification. Bone formation in soft tissues, often around the hip after ORIF, that can limit motion.
• Mental Health Effects. PTSD, depression, and anxiety after a severe motor vehicle crash. Often missed and almost always undertreated.

Kentucky Law and Pelvic Fracture Settlements

The legal side of a pelvic-fracture case in Kentucky runs on three rules most people never hear about until it is too late.

The deadline is shorter than people think. Under KRS 304.39-230, a Kentucky motor vehicle injury claim must be filed within 2 years of the last basic reparation (PIP) payment, not 2 years from the crash. If PIP was never paid or never opened, the clock starts on the crash date. Either way, severe injuries with extended hospital stays burn through statute time fast while the person is still recovering.

PIP coverage in Kentucky is optional. Most drivers carry the basic $10,000, which barely covers the trauma bay. Kentucky lets drivers reject no-fault entirely (KRS 304.39-060). A pelvic fracture client who rejected no-fault is in a different posture than one who carries PIP, and we work the medical-bill side accordingly.

UIM stacking is allowed in Kentucky. Underinsured motorist coverage on more than one policy can sometimes be stacked, depending on policy language. With a six-figure or seven-figure pelvic injury and a defendant who only carries $25,000 in liability coverage, the UIM stack often becomes the actual settlement source.

We handle the entire insurance fight from day one. You focus on getting better. We will handle everything else.

What Drives the Settlement Range on a Pelvic Fracture

Pelvic fractures vary widely, and so do the settlements. The number is built from these factors, weighed against liability and available coverage.
