Can you interpret the X‑ray findings for a 66‑year‑old patient who fell onto a wooden chair and now presents with right shoulder, hip, knee, hand, and jaw pain with limited mouth opening?

X-Ray Interpretation for Multi-Site Trauma Following Fall

For this 66-year-old patient with multiple injury sites following a fall, obtain standard radiographs of each symptomatic area as the initial imaging study: right shoulder (AP in internal/external rotation plus axillary or scapula-Y view), right hip (AP with 15° internal rotation plus cross-table lateral), right knee (AP and lateral), bilateral hands (PA and lateral), and jaw/mandible (panorex or mandibular series). 1, 2, 3

Algorithmic Approach to X-Ray Interpretation

Right Shoulder Pain

• Look for: Proximal humerus fractures (head or neck), acromioclavicular joint separation, glenohumeral dislocation
• Critical views: The axillary or scapula-Y view is essential—AC and glenohumeral dislocations are frequently misclassified on AP views alone 1, 2
• Age consideration: At 66 years old, this patient fits the bimodal distribution for proximal humerus fractures from low-energy trauma (falls from standing) 1
• If fracture identified: CT without contrast is the next step to characterize fracture patterns and guide surgical planning, as radiographs show poor inter-observer agreement for grading humeral head fractures 1

Right Hip and Knee Pain with Swelling

• Hip imaging priority: This is critical for morbidity/mortality—delays in hip fracture diagnosis increase 30-day mortality, complication rates, and hospital length-of-stay 3
• Look for: Femoral neck fractures (intracapsular vs extracapsular), intertrochanteric fractures, hip dislocation
• If radiographs negative but high clinical suspicion: MRI without contrast is the most sensitive next step for occult hip fractures 3
• Knee: Assess for fractures, joint effusion suggesting hemarthrosis, ligamentous injury indicators

Bilateral Hand Pain

• Common pitfall: Small bone fractures (scaphoid, pisiform) are frequently missed on initial radiographs 4
• Look for: Metacarpal fractures, phalangeal fractures, carpal bone fractures
• If initial films negative with persistent symptoms: Consider CT or follow-up radiographs in 10-14 days when periosteal reaction becomes visible 5

Jaw Pain with Limited Mouth Opening

• Look for: Mandibular fractures (condyle, angle, body), temporomandibular joint dislocation
• Clinical correlation: Limited mouth opening (trismus) suggests condylar involvement or TMJ injury
• If radiographs equivocal: CT without contrast provides superior fracture characterization

Key Interpretation Principles

Radiographs remain the initial study despite limitations because they:

• Rapidly identify displaced fractures and joint dislocations requiring immediate intervention 1, 2, 3
• Can be obtained portably, reducing morbidity from patient movement 3
• Provide anatomic overview for planning advanced imaging 5

Sensitivity limitations to recognize:

• Early fractures (<14 days) may show only soft tissue swelling 6
• Radiographs have 15-35% sensitivity for stress fractures initially, increasing to 30-70% on 10-14 day follow-up 5
• Nondisplaced fractures and complex anatomy can be underappreciated 1

Critical Red Flags Requiring Advanced Imaging

Obtain CT without contrast if:

• Complex or comminuted fracture patterns on radiographs 1
• High clinical suspicion with negative radiographs in hip (use MRI instead) 3
• Scapular fracture suspected (frequently missed on radiographs) 7

Do NOT obtain:

• MRI with and without contrast (no role in acute trauma) 2, 3
• FDG-PET/CT (not routinely performed for trauma) 1
• Bone scan (poor spatial resolution, delays diagnosis) 5, 6

Additional Clinical Context Impact

Untreated hypothyroidism (off thyroxine × 2 months):

• May contribute to falls via fatigue, weakness, disorientation
• Does not change imaging approach but increases fracture risk
• Requires urgent thyroid function testing and medication resumption

History of dizziness/disorientation on standing:

• Suggests orthostatic component to fall mechanism
• Does not change initial imaging but warrants cardiovascular/neurologic evaluation

Chest congestion/cough:

• If rib tenderness present, add chest radiograph to evaluate rib fractures
• Upper chest tightness could represent musculoskeletal injury from fall impact

The imaging interpretation must be completed urgently—particularly for the hip—as surgical delays beyond 12 hours significantly increase mortality in this age group 3.
