Usual Contusion Healing Time Secondary to Blunt Trauma
Simple soft tissue contusions (bruises) from blunt trauma typically resolve within 2-3 weeks in most patients, with visible discoloration fading progressively over this period.
General Healing Timeline
Superficial soft tissue contusions generally show significant improvement within 7-14 days, with complete resolution by 2-3 weeks in uncomplicated cases (based on general medical knowledge and extrapolation from trauma healing patterns).
The healing process follows a predictable pattern: initial swelling and discoloration (days 1-3), color changes from red/purple to green/yellow (days 4-10), and gradual fading (days 10-21).
Organ-Specific Contusion Healing (When Applicable)
While the question asks about general contusions, understanding organ-specific healing provides context for more severe injuries:
Splenic Contusions
- Minor injuries (grades I-II): Average healing of 12.5 days with complete healing by 50 days 1.
- Moderate to severe injuries (grades III-V): Average healing of 37.2 days with complete healing by 75 days 1.
- Overall: Regardless of severity, 84% of patients show complete healing by 2-2.5 months 1.
Bladder Contusions
- Uncomplicated bladder contusions managed conservatively heal within 10 days in more than 85% of cases 1.
Pulmonary Contusions
- Young, healthy patients with isolated pulmonary contusion typically show clinical improvement within 48-72 hours, though radiographic changes may persist longer 2.
Factors Affecting Healing Time
Severity of impact directly correlates with healing duration—deeper tissue involvement extends recovery time beyond the typical 2-3 week window.
Patient age and comorbidities significantly influence healing:
- Elderly patients or those with coagulopathies may experience prolonged healing
- Patients on anticoagulation require individualized assessment 1
Location of contusion matters:
- Areas with better vascular supply heal faster
- Contusions over bony prominences may take longer due to repeated minor trauma
Activity Restrictions
- Minor soft tissue contusions: Activity restriction of 2-4 weeks is reasonable to prevent re-injury.
- More significant injuries: Activity restriction may extend to 4-6 weeks for minor organ injuries and 2-4 months for moderate to severe organ injuries 1.
Common Pitfalls
Do not dismiss persistent pain or swelling beyond 3 weeks—this may indicate complications such as:
- Compartment syndrome (requires urgent evaluation)
- Underlying fracture missed on initial assessment
- Development of hematoma or seroma
- Vascular injury with pseudoaneurysm formation
Avoid premature return to contact activities—even when visible bruising has resolved, underlying tissue healing may be incomplete, increasing risk of re-injury or more severe complications.
Monitor for delayed complications in the first 48 hours to 10 days post-injury, as this is when delayed rupture or other complications are most likely to occur in organ contusions 1.
When to Image or Escalate Care
- Persistent symptoms beyond 2-3 weeks warrant re-evaluation
- Expanding hematoma or new neurological symptoms require urgent imaging
- Signs of compartment syndrome (severe pain, paresthesias, pallor) require immediate surgical consultation
