Effective Hip Injury Management After a Car Accident

After a car accident, most attention goes to the neck, back, and whiplash—but many patients actually have occult hip injuries that are missed at first. Standard ER imaging often looks “normal,” and symptoms get blamed on the low back or sacroiliac (SI) joint instead of the hip joint and labrum.

At SIGMA Orthopedics & Sports Medicine, we’ve developed a Head-and-Hip Injury Protocol to systematically evaluate the hip after motor vehicle accidents, especially when pain, instability, or clicking just don’t match a simple lumbar strain.

Why Hip Injuries Are Often Missed After Car Accidents

After a motor vehicle accident, many patients are told they have “whiplash” or “low back strain,” even though their main pain generator is the hip. ER X-rays can look normal, and standard lumbar-focused exams may not stress the hip enough to reveal a labral tear, femoroacetabular impingement (FAI), or soft-tissue injury.
As a hip and sports medicine specialist, Dr. McCormick frequently sees patients who have been through weeks or months of spine-centered care—chiropractic treatments, lumbar MRI, injections—before anyone takes a deep, structured look at the hip. That’s where the SIGMA Head-and-Hip Injury Protocol comes in.

At SIGMA, our goal is simple: find the exact source of your pain, fix it with precision, and guide you through a data-driven return to full activity.

Common Signs of a Missed Hip Injury After a Car Accident

If your neck and back treatments haven’t fixed your symptoms, it may be time to look carefully at the hip joint, labrum, and surrounding tendons.

2. Peri-hip soft-tissue injuries

3. True traumatic injuries

4. Overlapping or confounding sources

The SIGMA Head-and-Hip Injury Protocol for MVAs

Most patients start to feel better within 4–6 weeks of structured non-operative care, and can return to sport or higher-level activity within 8–12 weeks, depending on severity and goals.

Phase I

Detailed Mechanism & Symptom Mapping

  • Seatbelt position, seat position, airbag deployment
  • Direction of impact (front, rear, side, rollover)
  • Dashboard or console contact with the knees or hip
  • Symptom timeline: immediate vs delayed; hip/groin vs low back vs lateral hip

Phase II

Targeted Physical Exam

  • Compare hip vs lumbar vs SI joint as pain sources
  • Labral and impingement tests (FADIR, FABER, log roll)
  • Hip abductor strength and Trendelenburg assessment
  • Palpation of greater trochanter, SI joint, and lumbar facets

Phase III

3. Advanced, Hip-Specific Imaging When Needed

  • Weight-bearing X-rays of the hip and pelvis
  • High-resolution MRI or MR arthrogram to evaluate the labrum and cartilage
  • Ultrasound to assess tendons and bursae
  • Use of diagnostic injections (hip joint vs SI vs trochanteric bursa) to clarify pain sources

Phase IIII

Multidisciplinary Correlation

  • Collaboration with spine specialists, pain management, and physical therapists
  • Clear documentation for patients and, when requested, for attorneys and case managers regarding mechanism, causation, and prognosis.
Throughout this process, we track your progress using outcome scores and strength benchmarks, just like a pilot uses instruments in the cockpit. The goal: a predictable return to sport with fewer surprises.

Present a Clear Treatment Pathway for MVA Hip Injuries

How We Treat Hip Injuries After Car Accidents
Stage 1
Calm Pain & Protect the Hip
  • Activity modification, assistive devices when needed
  • Targeted medications and short-term anti-inflammatory strategies
  • Early PT focused on gentle motion, core and pelvic stabilization
Stage 2
Correct Mechanics & Rebuild Strength
  • Focused PT on hip abductors, rotators, and core
  • Gait retraining, single-leg stability, and functional movement
  • Address compensations from lumbar spine or SI joint
Stage 3
Advanced Interventions
  • Image-guided injections: intra-articular hip, trochanteric bursa, or SI joint as appropriate
  • Orthobiologic options (SynerG™ PRP/A2M/etc.) for select soft-tissue injuries and persistent pain
Stage 4
Surgical Solutions When Indicated
  • Arthroscopic labral repair and FAI correction
  • Hip abductor or proximal hamstring repair when torn
  • Coordination with your broader MVA care team to align surgery with work, rehab, and legal timelines

Surgery for trochanteric bursitis is not common. When it is needed, we apply the same checklist-driven, minimally invasive philosophy used in our hip arthroscopy and abductor repair programs.

Attorneys & Case Managers

For Attorneys and Case Managers: Clarifying Hip Involvement After MVAs

Many motor vehicle accident cases hinge on whether ongoing pain is due to the spine, the hip, or both. Our SIGMA Head-and-Hip Protocol provides structured documentation of mechanism of injury, objective findings, imaging correlation, and prognosis. We frequently work with attorneys and case managers to provide clear, medically grounded opinions on hip involvement, impairment, and future treatment needs when appropriate.

Hip Injuries After Car Accidents – FAQs

X-rays are great for detecting fractures and dislocations, but they don’t show the labrum, cartilage, or many soft-tissue injuries. Labral tears, early impingement damage, and tendon injuries often require MRI or MR arthrogram plus a focused exam.
Hip joint pain is often felt deep in the groin or front of the hip, especially with motion. Lumbar radiculopathy usually follows a nerve pattern down the leg. The SIGMA protocol uses exam maneuvers and diagnostic injections to separate the two.
That’s exactly when we start to suspect an occult hip injury. Our evaluation looks beyond the spine to the labrum, cartilage, and surrounding hip structures.

Still Hurting After a Car Accident? It Might Be Your Hip.

If you’ve been through ER visits, spine evaluations, or chiropractic care and still don’t have a clear answer for your hip or groin pain, a focused SIGMA Head-and-Hip Evaluation may help uncover what others have missed. Our goal is to give you clarity, a precise diagnosis, and a practical plan forward.

Introduction

Hip injuries resulting from motor vehicle accidents (MVAs) are common and can range from minor contusions to severe fractures or dislocations. The management of these injuries requires a systematic approach, encompassing immediate care, diagnostic procedures, treatment options, and long-term rehabilitation. This report outlines a comprehensive strategy for managing hip injuries following car accidents, focusing on assessment, treatment, and recovery.

Initial Assessment and Emergency Care:

1. Scene Assessment and Triage:
– Ensure scene safety
– Perform primary survey (ABCDE approach)
– Immobilize the patient if spinal injury is suspected

2. Pre-hospital Care:
– Provide pain management
– Apply pelvic binder if pelvic fracture is suspected
– Initiate fluid resuscitation if signs of shock are present

3. Emergency Department Evaluation:
– Conduct secondary survey
– Obtain detailed history of the accident mechanism
– Perform focused hip and pelvis examination
– Assess neurovascular status of lower extremities

Diagnostic Procedures:

1. Imaging Studies:
– Plain radiographs (AP pelvis, lateral hip)
– CT scan for detailed fracture assessment
– MRI for soft tissue injuries and occult fractures

2. Laboratory Tests:
– Complete blood count
– Coagulation profile – Serum electrolytes and renal function tests

3. Additional Investigations:
– Angiography if vascular injury is suspected
– Nerve conduction studies for neurological deficits

Classification of Hip Injuries:

1. Fractures:
– Femoral head fractures
– Femoral neck fractures
– Intertrochanteric fractures
– Subtrochanteric fractures

2. Dislocations:
– Posterior hip dislocations
– Anterior hip dislocations

3. Soft Tissue Injuries:
– Labral tears
– Muscle strains (e.g., iliopsoas, rectus femoris)
– Ligamentous injuries

4. Combined Injuries:

The management of hip injuries following car accidents requires a comprehensive, multidisciplinary approach. From initial assessment and emergency care to long-term rehabilitation and follow-up, each stage plays a crucial role in optimizing patient outcomes. By adhering to evidence-based protocols, individualizing treatment plans, and staying abreast of emerging technologies and techniques, healthcare providers can effectively manage these complex injuries and help patients regain optimal function and quality of life.
