MissedFractureDiagnosis

Missed-fracture patterns have been studied extensively in the radiology and emergency-medicine literature. Recurring drivers:

• Subtle fracture lines. Scaphoid fractures at the wrist often do not appear on initial X-rays — the fracture line is not radiographically visible until 10-14 days later when bone resorption widens the gap. Occult hip fractures in elderly osteoporotic bone can be invisible on plain films but readily seen on MRI.
• Specific views not obtained. Dedicated scaphoid views (ulnar deviation PA, pronated oblique) are required for scaphoid imaging. Without them, the fracture may be entirely missed. The same applies to Judet oblique views for acetabular fractures, mortise views for ankle, or odontoid views for cervical spine.
• Plain films not sensitive enough. Occult hip fractures in elderly patients, sacral fractures, subtle stress fractures, and certain carpal injuries require MRI or CT when plain films are negative and clinical suspicion remains. Discharging a patient with a negative X-ray in a high-suspicion presentation — without ordering the more sensitive study — is a recognized failure pattern.
• High-volume reading. Radiologists work under significant volume pressure. Dozens or hundreds of reads per shift, with subtle fractures scattered among predominantly normal studies. Fatigue and anchoring bias both contribute to missed findings.
• Satisfaction of search. Once a radiologist identifies one finding, the search for additional findings may be curtailed. A rib fracture is identified; a more subtle pneumothorax is missed. A carpal injury is identified; a scaphoid fracture is missed.
• Distracting injuries. In polytrauma, attention focuses on the obvious life-threatening injury. Cervical spine, pelvic, and extremity fractures are classically missed in this setting. Tertiary survey on day 2-3 is a trauma-protocol safeguard for exactly this reason.
• Pediatric anatomy. Pediatric fractures present differently — greenstick fractures with subtle cortical buckling, Salter-Harris injuries requiring specific views, physeal fractures invisible on plain film in young children. Radiologists without pediatric experience are more likely to miss them.
• Anchoring on sprain. Ordering providers who receive a negative initial read and have already provisionally diagnosed a sprain may not pursue further imaging even when symptoms persist.

A handful of fracture types account for the majority of missed-fracture litigation:

Scaphoid Fractures

The classic missed fracture. The scaphoid is the most commonly fractured carpal bone, and initial X-rays miss roughly 15% to 25% of scaphoid fractures. The fracture line may not be visible for 10-14 days. Standard of care for suspected scaphoid injury (snuffbox tenderness, axial load pain, mechanism consistent with scaphoid) is either immobilization with repeat X-ray in 10-14 days, or MRI at presentation. Discharge with "sprain" and no follow-up imaging is the recurring failure pattern. Missed scaphoid fractures progress to non-union and avascular necrosis of the proximal pole, leading to scapholunate advanced collapse (SLAC) wrist arthritis — a devastating outcome requiring wrist fusion or arthroplasty.

Occult Hip Fractures

Elderly patients with osteoporotic bone can have intertrochanteric or femoral neck fractures that do not appear on plain films. When clinical presentation suggests fracture (inability to bear weight, groin pain, externally rotated leg) and X-rays are negative, MRI is indicated. Missed hip fractures in elderly patients allowed to continue weight-bearing can displace from non-displaced to displaced — converting a percutaneous pinning procedure into a hemiarthroplasty or total hip replacement, with substantially higher complication rates and mortality in elderly patients.

Pediatric Fractures

Pediatric fractures — greenstick, buckle (torus), Salter-Harris physeal fractures — present with subtle radiographic findings that require experience to identify. Missed pediatric fractures with continued activity can displace, delay healing, or disturb growth plates leading to limb length discrepancy or angular deformity. Non-accidental trauma (child abuse) fractures — spiral fractures of long bones, metaphyseal corner fractures, posterior rib fractures — missed on initial imaging also produce serious legal consequences distinct from simple diagnostic-error cases.

Cervical Spine Fractures

In polytrauma patients, cervical spine injuries can be missed when distracting injuries dominate. Inadequate cervical spine imaging — not enough views, or CT not ordered when clinically indicated — combined with premature clearance of the cervical spine can lead to continued motion with unstable injuries and neurologic deterioration. NEXUS and Canadian C-Spine Rule criteria guide clinical clearance; deviation from those rules in high-risk patients is a recognized failure pattern.

Rib Fractures

Rib fractures are frequently missed on initial chest X-ray. In elderly patients, rib fractures are associated with pneumonia and mortality; in polytrauma, they signal underlying lung injury. Missing rib fractures often means missing the underlying complication — hemothorax, pneumothorax, or splenic or hepatic injury in lower rib fractures.

Stress Fractures

Stress fractures of the tibia, metatarsals, navicular, and femoral neck often do not appear on initial plain films. Clinical suspicion (focal bone tenderness in an at-risk patient — runner, military recruit, athlete) mandates MRI or bone scan. Missed stress fractures progress to complete fractures with activity.

Fracture diagnosis standards converge on several layers:

• Appropriate imaging selection. Plain films for most extremity trauma — with specific additional views as indicated (scaphoid views, mortise view of ankle, axial views of knee, Judet views of pelvis). CT for pelvic, acetabular, and complex intra-articular fractures. MRI when plain films are negative but clinical suspicion remains — occult hip, scaphoid, sacral, stress fractures.
• Competent radiologist interpretation. The American College of Radiology publishes Appropriateness Criteria and diagnostic guidelines. Board-certified radiologists are expected to identify visible fractures at the standard of care.
• Clinical correlation. The treating provider (ER physician, urgent-care physician, orthopedist) correlates imaging with clinical findings. A negative X-ray in a patient with classic scaphoid-injury findings does not rule out scaphoid fracture — it mandates repeat imaging or MRI.
• Appropriate follow-up. Negative initial imaging with persistent symptoms mandates either repeat imaging (scaphoid at 10-14 days) or advanced imaging (MRI for occult hip fracture). Discharge with pain medication and no follow-up plan in a concerning presentation is a recognized failure.
• Communication of findings. The radiologist\'s report must reach the treating provider. Closed-loop communication of positive findings, particularly findings that change management, is increasingly standard.
• Subspecialty review. For complex cases, musculoskeletal radiology consultation. Pediatric radiology for pediatric cases. Trauma radiology for polytrauma tertiary survey.

Departures from these expectations — particularly missing a fracture visible on the initial study, or failing to order MRI for an occult hip fracture presentation — are the substance of most missed-fracture malpractice cases.

Missed-fracture cases are imaging-driven. The essential records:

• Original imaging files. DICOM files of the initial X-ray, CT, or MRI. Not just the radiologist\'s report — the actual images, at full resolution, for independent review.
• Radiologist\'s original report. The dictated interpretation, with specific attention to whether the fracture site was described as normal, whether additional views were recommended, and whether follow-up imaging was advised.
• Initial clinical record. The ER or urgent-care note documenting mechanism of injury, physical examination (specifically documented — snuffbox tenderness for scaphoid, inability to bear weight for hip), discharge diagnosis, and return precautions.
• Subsequent confirming imaging and records. The imaging that eventually identified the fracture. Orthopedic evaluation, surgical records if surgery was performed, treatment of any complications (non-union, avascular necrosis, growth disturbance).
• Second-read review. Independent interpretation of the original imaging by a subspecialty radiologist — typically a musculoskeletal radiologist for orthopedic cases. This is the core evidence that the fracture was visible and should have been reported.
• Functional outcome documentation. Physical therapy notes, orthopedic follow-up, any subsequent surgery for complications — documenting the harm the delay caused.

Under Florida Statute § 766.102, the corroborating expert affidavit is mandatory. For missed-fracture cases, that affidavit is often supplied by the musculoskeletal radiologist performing second-read review. An orthopedic surgeon may also be retained for causation and damages analysis.

Missed-fracture cases often involve multiple defendants:

• Radiologist. Typically the primary defendant when the fracture was visible on the original study. Radiology contract groups are almost always separately insured from the hospital.
• Ordering provider. ER physician, urgent-care physician, or primary care physician who relied on the negative read and did not pursue further workup despite concerning clinical findings.
• Orthopedic consultant. Where orthopedics was consulted and agreed with the initial assessment, the consultant may face liability.
• Mid-level providers. PAs or NPs involved in the evaluation and their supervising physicians.
• Hospital. Vicariously liable for employed providers; directly liable for institutional failures — inadequate imaging equipment, unavailable subspecialty radiology, defective PACS communication of findings.
• Radiology group and ER contract group. Separate corporate entities with their own insurance.

Missed-fracture damages are calculated against the counterfactual — what the treatment and outcome would have been with timely diagnosis:

• Past medical expenses — the more complex surgery the delay required, bone grafting for non-union, joint replacement for avascular necrosis, extended physical therapy, pain management, ongoing orthopedic follow-up.
• Future medical expenses — continued care for lasting complications, anticipated revision surgery, ongoing pain management.
• Lost earnings during the extended recovery and treatment of complications — weeks or months beyond what uncomplicated treatment would have required.
• Lost earning capacity where lasting functional limits affect work — loss of grip strength after scaphoid non-union, loss of ambulation capacity after displaced hip fracture, loss of athletic function. Manual-labor workers, surgeons, dentists, musicians, and athletes have particularly high lost-capacity exposure.
• Pain and suffering for the extended pain, the surgery, the functional limits. Uncapped in Florida after North Broward Hospital District v. Kalitan, 219 So. 3d 49 (Fla. 2017).
• Loss of consortium for a spouse whose relationship was affected by the functional limits.
• Pediatric damages — future costs from growth disturbance, limb length discrepancy, angular deformity, or other developmental complications.

Florida Statute § 95.11(4)(b) governs medical malpractice limitations. For missed fractures, the two-year discovery clock typically runs from when the patient learned the fracture had been missed — often the correct diagnosis or the surgery for a complication. For pediatric cases with growth disturbance that emerges over years, Florida\'s extension for minors provides additional time under the Medical Malpractice Act.

The 90-day pre-suit investigation period and § 766.102 corroborating expert affidavit are mandatory. In missed-fracture cases, the corroborating expert is typically the musculoskeletal radiologist whose second-read review establishes that the fracture was visible on the original imaging.

If you or a family member received a diagnosis of sprain, contusion, or "no acute fracture" on initial imaging and then subsequently was diagnosed with a fracture — or developed non-union, avascular necrosis, or growth disturbance — the early steps:

1. Preserve the original imaging. Request DICOM files of the initial X-ray, CT, or MRI. The actual images, not just the radiologist\'s report.
2. Preserve the confirming imaging. The eventual imaging that identified the fracture. Comparison of the two is central to the case.
3. Preserve clinical records. Initial ER or urgent-care note, subsequent visits, orthopedic consultation, surgical records, physical therapy records.
4. Document the functional impact. Work missed, activities avoided, pain levels, any subsequent complications.
5. Consult a Florida medical malpractice attorney. The consultation is free. A qualified firm will obtain the imaging, arrange independent second-read review by a musculoskeletal radiologist, and tell you honestly whether the case meets Florida\'s pre-suit requirements under § 766.102.
