Management of Elbow Contusion
For an elbow contusion, initiate immediate active exercises without immobilization, as this approach results in significantly faster recovery (1 week vs 2 weeks) compared to immobilization. 1
Initial Assessment and Imaging
Start with plain radiographs as the first-line imaging to exclude fracture or dislocation 2. The ACR Appropriateness Criteria (2024) clearly designate radiography as "usually appropriate" for acute elbow trauma. Key radiographic findings to assess:
- Fat pad signs: Posterior and anterior fat pad elevation indicates joint effusion and may suggest occult fracture even when no obvious fracture line is visible
- Avulsion fractures at tendon/ligament attachment sites
- Joint alignment to exclude dislocation
Critical Pitfall
Even with "normal" radiographs showing only effusion, up to 38% may have occult fractures that were initially missed 1. However, this does not change initial management—these patients still recover fully with active exercise.
Treatment Protocol
Week 1: Immediate Active Mobilization
- No immobilization or casting 1
- Begin active-assisted range of motion exercises immediately
- Include overhead motion (active flexion/extension with arm overhead) 3
- Apply cryotherapy and compression for pain/swelling control 3
- Avoid varus/valgus stress during this period 3
Clinical Reasoning
The landmark prospective randomized study of 62 patients demonstrated that immediate active exercises produced significantly shorter recovery times (median 1 week) compared to 1 week of plaster immobilization (median 2 weeks, P < 0.05) 1. Importantly, even patients with missed fractures on initial radiographs recovered fully with this approach, validating the safety of early mobilization.
Week 2 Onward
- Clinical re-examination at 1 week 1
- Obtain repeat radiographs only if clinical progress is unsatisfactory 1
- If a dynamic orthosis is needed (rare for simple contusion), allow free range of motion while protecting against varus/valgus stress 3
Loading Progression
- Avoid loading for first 6 weeks 3
- Stepwise increase in loading after 6 weeks
- Return to sport typically possible at 3 months 3
When to Escalate Imaging
If radiographs are normal/indeterminate but clinical suspicion for fracture remains high:
- CT without contrast is the next appropriate study for detecting occult fractures 2
- Studies show CT detects 12.8% of occult fractures missed on radiographs, particularly radial head, olecranon, and coronoid process fractures 2
- MRI is not indicated as initial imaging for simple contusion 2
Key Principles
The elbow joint is highly susceptible to post-traumatic stiffness 3. Mid-term to long-term immobilization must be avoided to prevent this complication. The evidence strongly supports that early active mobilization—even in the presence of joint effusion or occult fracture—leads to superior functional outcomes without adverse effects 1.
