What is the appropriate management for elbow pain?

Elbow Pain Management

Begin with plain radiographs as your initial imaging study for both acute and chronic elbow pain, followed by conservative management including rest, activity modification, physical therapy, and NSAIDs, reserving advanced imaging and interventions for cases that fail to respond or have specific clinical indicators. 1, 2

Initial Diagnostic Approach

Imaging Strategy

Radiographs are the appropriate first-line imaging modality for elbow pain regardless of whether it's acute or chronic 1, 2. Plain films can identify:

• Fractures (radial head/neck fractures account for 50% of adult elbow fractures)
• Joint effusions (anterior and posterior fat pad elevation suggesting occult fracture in acute trauma)
• Intra-articular loose bodies
• Heterotopic ossification
• Osteochondral lesions
• Soft tissue calcifications
• Osteoarthritis
• Avulsion fractures at tendon/ligament attachment sites

Do not order CT, MRI, or bone scans as initial imaging - there is no evidence supporting their use as first-line studies 1, 2. Reserve advanced imaging for when radiographs are normal or nonspecific but clinical suspicion remains high for intra-articular pathology.

Clinical Evaluation Focus

Look specifically for:

• Epicondylalgia (most common cause of chronic elbow pain, affecting 1-3% of population): lateral ("tennis elbow") involves common extensor tendon; medial ("golfer's elbow") involves common flexor tendon 2
• Mechanical symptoms (locking, catching) suggesting loose bodies or osteochondral lesions
• Neurological symptoms (numbness, tingling) indicating cubital tunnel syndrome or ulnar neuritis
• Instability requiring stress testing under fluoroscopy for ligamentous injury
• Occupational or recreational risk factors

Conservative Management Algorithm

First-Line Treatment (All Patients)

Implement conservative measures as initial therapy 2:

• Rest and activity modification (reduce aggravating activities)
• Analgesia (NSAIDs for pain control)
• Physical therapy including:
  • Manual therapy techniques
  • Prescribed exercises
  • Stretching programs
• Corticosteroid injections for refractory cases

Important caveat: Low-certainty evidence suggests manual therapy and prescribed exercises may provide only slight pain reduction (mean difference -0.53 points on 0-10 scale) and disability improvement (mean difference -5.00 points on 0-100 scale) at 4 weeks to 3 months, with effects not sustained long-term 3. However, these remain standard first-line approaches given their safety profile and lack of superior alternatives.

Intermediate Interventions (If Conservative Fails)

Consider these before surgery 4:

• Extracorporeal shockwave therapy
• Platelet-rich plasma injections
• Prolotherapy
• Ultrasound-guided percutaneous tenotomy

Surgical Indications

Reserve surgery for 2, 4:

• Severe or refractory cases failing 6+ months of conservative treatment
• Collateral ligament injuries requiring repair
• Biceps tendon injuries
• Cubital tunnel syndrome with progressive neurological deficits
• Osteochondral abnormalities
• Loose bodies causing mechanical symptoms
• Gross instability (frank redislocation on stress testing)

Advanced Imaging - When and What to Order

If Radiographs Normal but Suspicion for Intra-articular Pathology

Order MRI or MR arthrography for 2:

• Suspected osteochondral lesions
• Loose bodies (MR arthrography has 100% sensitivity)
• Ligamentous injuries (UCL tears, lateral collateral ligament complex)
• Tendon pathology assessment
• Synovial abnormalities

Order CT or CT arthrography for 2:

• Better visualization of heterotopic ossification
• Loose body detection (93% sensitivity, 66% specificity)
• Osteophyte assessment
• When MRI contraindicated

Special Considerations

Stress radiographs are useful for detecting medial joint line opening and valgus instability - compare to contralateral asymptomatic elbow 2. Dynamic fluoroscopy can distinguish stages of collateral ligament injury 1.

Electromyography assists specifically in workup of nerve-related symptoms like cubital tunnel syndrome 2.

Common Pitfalls to Avoid

1. Don't skip plain radiographs - jumping directly to MRI wastes resources and may miss obvious bony pathology
2. Don't order advanced imaging initially unless there's acute trauma with high suspicion for complex injury requiring surgical planning
3. Don't rush to surgery - most epicondylalgia cases respond to conservative management over time
4. Don't ignore the contralateral side - comparison views are often diagnostically useful 2
5. Don't assume single pathology - medial elbow complaints are often multifactorial (tendinopathy + ulnar neuritis + ligament injury) 4

Treatment Outcomes and Expectations

Adverse events from manual therapy and exercise are typically mild and transient (pain, bruising), with no serious adverse events reported 3. However, patients should understand that while conservative treatment may provide modest short-term benefit, effects may not be clinically significant or sustained long-term, necessitating ongoing management strategies.
