Should a splint be used in the treatment of a left radial head fracture?

Treatment of Left Radial Head Fracture: Splint Recommendation

Yes, a splint should be used in the treatment of a left radial head fracture to reduce pain, prevent further injury, and facilitate safe transport and initial management 1.

Initial Immobilization Approach

For radial head fractures, immobilization is a fundamental component of treatment, though the specific approach depends on fracture displacement and stability:

For Minimally Displaced Fractures

• Removable splints are an acceptable option for minimally displaced radial head fractures 2
• This recommendation carries weak strength due to limited high-quality evidence, but represents standard practice

For Displaced or Complex Fractures

• Rigid immobilization is preferred over removable splints when treating displaced fractures 2
• This recommendation has moderate strength
• Post-surgical cases typically require plaster splint immobilization for 2-3 weeks 3
• Complex injuries (terrible triad, fracture-dislocations) require long-arm splinting post-operatively 4

Key Clinical Considerations

Immediate splinting serves multiple critical functions:

• Reduces pain and prevents further soft tissue injury
• Maintains fracture alignment during initial evaluation
• Facilitates safe transport to definitive care 1
• Protects associated ligamentous structures that are commonly injured with radial head fractures 5

Important Caveats

Watch for associated injuries - radial head fractures frequently occur with:

• Elbow dislocations (terrible triad injuries)
• Coronoid process fractures
• Collateral ligament ruptures
• These require more aggressive immobilization and often surgical intervention 5, 4, 3

Assess neurovascular status immediately - if the extremity appears blue, purple, or pale, activate emergency response immediately as this indicates limb-threatening injury 1

Practical Application Algorithm

1. Initial assessment: Determine fracture displacement and associated injuries
2. Minimally displaced/stable: Apply removable splint with elbow at 90° flexion
3. Displaced/unstable: Apply rigid immobilization; consider surgical referral
4. Post-reduction/post-operative: Plaster splint for 2-3 weeks 3
5. All patients: Instruct immediate active finger motion exercises to prevent stiffness 2

Duration of Immobilization

• Typical immobilization period: 2-4 weeks depending on fracture stability
• Early mobilization after stable fixation does not improve outcomes 2
• Finger motion should begin immediately regardless of immobilization method 2

Common Pitfalls to Avoid

Finger stiffness is the most functionally disabling complication 2. Even with the elbow immobilized, patients must perform active finger range of motion exercises from the first encounter. This is cost-effective, requires no additional visits, and significantly impacts outcomes.

Do not overlook associated injuries - approximately 50% of radial head fractures in adults involve the radial head or neck, but many occur with concurrent ligamentous injuries requiring different management 6, 5.

The evidence strongly supports splinting for radial head fractures, with the type of immobilization (removable vs. rigid) determined by fracture displacement and stability rather than whether to immobilize at all.
