A car accident can cause pain in parts of the body that many people have never thought about before the collision. One of those areas is the sacroiliac joint, commonly called the SI joint, which connects the lower spine to the pelvis. In Schaumburg, serious rear-end crashes, intersection collisions, side-impact accidents, and highway crashes can produce enough force to injure this joint and leave a person struggling with persistent lower back, hip, buttock, or leg pain.
The difficulty is that SI joint injuries are not always obvious immediately after the crash, and the symptoms can resemble other back and hip conditions. When I evaluate a sacroiliac joint injury claim after a car accident, I look closely at the medical evidence, the mechanics of the collision, the treatment history, and how the injury has affected the person’s ability to work and function normally.
The sacroiliac joints sit where the sacrum, which is the triangular bone at the bottom of the spine, connects with the pelvis. Trauma from a motor vehicle accident is a recognized cause of injury to the sacroiliac joint, and symptoms may include pain in the lower back, buttocks, legs, or groin. Because these symptoms overlap with lumbar disc injuries, hip injuries, and other musculoskeletal conditions, properly identifying the source of the pain can become an important issue in a personal injury claim.
How A Car Accident Can Injure The Sacroiliac Joint
The forces generated during a motor vehicle collision can cause the body to move violently in several directions within a fraction of a second. A rear-end impact may push the pelvis forward while the upper body moves differently. A side-impact collision may transmit substantial force directly through the hip and pelvic region. A rollover or high-speed impact can place additional stress on the joints connecting the spine and pelvis.
The sacroiliac joint is designed to transfer forces between the upper body and the legs. When abnormal force is suddenly applied during a crash, the tissues surrounding the joint may become irritated or injured. Mayo Clinic specifically identifies a sudden impact from a motor vehicle accident as one potential cause of sacroiliac joint problems.
In some cases, the accident may cause a new SI joint condition. In others, a collision may aggravate an existing but previously manageable condition. I do not automatically assume that a prior history of back or pelvic discomfort destroys a claim. The important question is whether the accident caused a new injury or materially worsened a preexisting condition.
Symptoms Of An SI Joint Injury After A Car Accident
SI joint pain commonly appears in the lower back or buttock region, but it can also radiate into the leg or groin. Some people experience pain primarily on one side, while others have symptoms affecting both sides. Activities such as prolonged sitting, standing, walking, stair climbing, or sleeping on the painful side can make symptoms worse.
These symptoms can be especially disruptive after a car accident because they affect basic movements. A person may have difficulty sitting at a desk, driving, standing for long periods, lifting, walking through a store, climbing stairs, or sleeping comfortably.
Persistent symptoms can also interfere with employment. Someone whose job requires standing, lifting, bending, driving, construction work, warehouse labor, or other physical activity may be unable to perform normal duties. Even people who work at a desk may struggle if prolonged sitting aggravates the injury.
When I evaluate damages, I look at how the injury affects the person’s actual daily life rather than focusing only on a diagnosis printed in a medical chart.
Why SI Joint Injuries Can Be Difficult To Diagnose
One challenge with sacroiliac joint injury claims is that lower back pain can have many different causes. A person may have a lumbar disc injury, muscle injury, facet joint problem, hip injury, nerve irritation, or SI joint dysfunction, and some of these conditions can exist at the same time.
Healthcare providers may evaluate the back, pelvis, hips, and legs and perform physical movements designed to identify where the pain originates. Imaging such as X-rays, CT scans, and MRI studies may also be used during the diagnostic process.
An MRI does not necessarily provide a simple answer to every SI joint complaint. For that reason, the overall medical record can become extremely important. I look for consistency between the accident, the onset of symptoms, physical examinations, specialist evaluations, diagnostic testing, treatment recommendations, and the patient’s response to treatment.
The more clearly the medical documentation connects the collision to the SI joint condition, the more difficult it becomes for an insurance company to dismiss the injury as unrelated.
Treatment Can Become An Important Part Of The Claim
Treatment for sacroiliac joint pain varies depending on the severity and underlying cause. Physical therapy is commonly used to improve strength and stability around the joint. Medications may be prescribed to address pain or inflammation. Some patients receive corticosteroid injections directly into the affected joint, and other treatments such as radiofrequency ablation may be considered in certain situations. Surgery is less common, but joint fusion may be considered when other treatments have not relieved severe symptoms.
From a legal standpoint, the treatment history helps demonstrate both the seriousness of the injury and the financial losses caused by the crash. I review emergency treatment, follow-up appointments, physical therapy, orthopedic or pain-management evaluations, injections, diagnostic studies, medications, missed work, and recommendations for future treatment.
An insurance company may try to characterize an SI joint injury as minor simply because there is no fracture. That does not necessarily reflect how significantly the condition affects a person’s ability to function.
Insurance Companies May Blame The Pain On Degeneration
SI joint claims can become disputed when imaging reveals arthritis or degenerative changes. Insurance adjusters sometimes argue that the accident did not cause the symptoms because some degeneration existed before the collision.
That argument does not necessarily answer the legal question.
A person may have age-related changes without experiencing disabling pain before an accident. If the collision aggravates an existing condition and causes new symptoms, increased treatment, or functional limitations, the accident may still be legally significant.
I examine the person’s medical history before the crash and compare it with the treatment required afterward. If someone was working, driving, exercising, and living normally before the collision but began experiencing significant SI joint symptoms afterward, that timeline can become important evidence.
Gaps In Treatment Can Complicate An SI Joint Claim
Insurance companies frequently examine the timing of medical treatment. If someone waits weeks before reporting lower back or pelvic pain, an adjuster may argue that the symptoms were caused by something other than the accident.
There can be legitimate reasons for delayed treatment. Some people initially believe their pain will improve on its own. Others focus on more obvious injuries first. Symptoms may also become more noticeable after the inflammation and soreness from the initial crash change over time.
Still, unexplained treatment gaps can create problems. I generally want the medical history to accurately document when symptoms began, how they progressed, and why there may have been interruptions in treatment.
Consistency is important. A sudden change in complaints months after a crash without supporting medical documentation may be more difficult to connect to the collision than symptoms repeatedly documented from the beginning.
Proving The Accident Caused The SI Joint Injury
A successful injury claim requires more than proving that someone was involved in an accident. I must also establish that another party was legally responsible and that the crash caused or aggravated the claimed injury.
Evidence may include the police report, photographs of vehicle damage, crash-scene images, witness statements, video footage, medical records, diagnostic testing, physician opinions, employment records, and testimony concerning how the injury changed the person’s life.
The mechanics of the collision can also matter. A substantial side impact involving the pelvis may support a different medical analysis than a very minor contact with little force. However, I do not rely solely on vehicle damage to determine whether an injury occurred. The medical evidence and the individual circumstances remain critical.
Damages In A Sacroiliac Joint Injury Claim
The value of an SI joint injury claim depends on the specific consequences of the injury. There is no automatic settlement amount simply because someone has been diagnosed with SI joint dysfunction or sacroiliitis.
I look at past medical bills, future treatment needs, lost wages, diminished earning ability, pain and suffering, disability, and the effect the condition has on daily activities. A person who completes several weeks of physical therapy and fully recovers presents a different damages picture than someone who requires injections, repeated pain-management care, radiofrequency procedures, or surgery.
The duration of the symptoms also matters. Persistent pain that affects work, sleep, mobility, recreation, and household responsibilities may substantially increase the overall impact of the injury.
Frequently Asked Questions About Sacroiliac Joint Injury Claims After A Car Accident
Can A Car Accident Really Cause An SI Joint Injury?
Yes. Sudden trauma from a motor vehicle collision is recognized as a possible cause of sacroiliac joint injury. The force of a rear-end, side-impact, head-on, or rollover crash can place substantial stress on the pelvis and lower spine. Whether a particular collision caused an individual’s SI joint condition must be evaluated using the accident circumstances and medical evidence. I look at when the symptoms began, the mechanism of the crash, examination findings, diagnostic testing, treatment history, and any prior medical problems.
What Does Sacroiliac Joint Pain Feel Like?
SI joint pain is commonly experienced in the lower back and buttock area. It may also extend into the leg or groin. Activities such as prolonged standing, walking, sitting, climbing stairs, or lying on the affected side can aggravate the symptoms. Because similar symptoms can result from lumbar disc injuries, hip problems, and other conditions, medical evaluation is important. A clear diagnosis can also become a significant part of establishing damages in a personal injury claim.
How Is An SI Joint Injury Diagnosed After A Car Accident?
Doctors may begin with a physical examination and review of the patient’s symptoms and medical history. They may assess range of motion, apply pressure around the SI joint, and perform movements intended to reproduce the pain. Imaging may include X-rays, CT scans, or MRI testing. In some situations, injections can also be used as part of treatment and evaluation. Because there is not always one single test that resolves every SI joint case, the complete medical history becomes important.
Can I Still Have A Claim If I Had Back Pain Before The Accident?
Possibly. A prior back condition does not automatically prevent a person from recovering compensation when an accident materially aggravates that condition. The central issue is what changed because of the collision. I compare pre-accident medical records with post-accident symptoms, treatment, restrictions, diagnostic testing, and functional limitations. If someone had occasional manageable discomfort before the crash but required extensive treatment afterward, that difference may become significant evidence.
