What is the best treatment for a male patient with a contusion and large hematoma of the right medial calf and shin?

Management of Contusion and Large Hematoma of the Right Medial Calf and Shin

For a male patient with a contusion and large hematoma of the right medial calf and shin, initiate conservative management with rest, ice, compression, and elevation (RICE), while actively monitoring for compartment syndrome and investigating for underlying coagulopathy. 1

Immediate Assessment and Monitoring

Assess for compartment syndrome urgently, as this is the most critical complication that can lead to permanent disability or limb loss:

• Monitor for progressive pain at rest, paresthesias, and increased tension/firmness of the calf 1, 2
• Measure serial calf circumferences to detect ongoing bleeding 1
• Evaluate for pain out of proportion to examination, which suggests compartment syndrome 2

Investigate for coagulopathy, particularly if the hematoma is disproportionately large for the mechanism of injury:

• Obtain prothrombin time (PT), activated partial thromboplastin time (aPTT), Clauss fibrinogen, and platelet count 1
• Check if patient is on anticoagulants or antiplatelet agents, as these significantly increase bleeding risk 3

Diagnostic Imaging

Obtain imaging to confirm diagnosis and rule out other pathology:

• Ultrasound can rapidly differentiate hematoma from deep vein thrombosis, Baker cyst, or tumor 4, 5
• CT or MRI provides definitive characterization of hematoma size, location, and extent 4
• Imaging is essential as spontaneous calf hematoma can be mistaken for deep vein thrombosis, which requires opposite management 3, 5

Conservative Management

Implement RICE protocol as initial therapy 6:

• Relative rest with elevation of the affected limb 1
• Ice application to minimize extension of injury 6
• Compression to control swelling 6
• Elevation to reduce hydrostatic pressure 1

Initiate gentle, painless range-of-motion exercises once acute pain subsides to restore mobility and prevent stiffness 6

Apply protective padding to prevent additional trauma to the affected area 6

Management of Coagulopathy (if present)

If coagulopathy is identified, aggressively correct it 1:

• For elevated INR: administer prothrombin complex concentrate (25-50 U/kg) and intravenous vitamin K (5-10 mg) 1
• Replace fibrinogen if low 1
• Transfuse platelets if thrombocytopenic 1

Surgical Intervention

Consider urgent surgical evacuation if:

• Compartment syndrome develops with elevated compartment pressures 2
• Progressive pain at rest despite conservative measures 2
• Hemodynamic instability or signs of ongoing bleeding 1
• Chronic hematoma causing significant functional impairment 3

Surgical approach involves fasciotomy and complete evacuation of the hematoma 2

Thromboprophylaxis

Initiate low-molecular-weight heparin for thromboprophylaxis as soon as bleeding is controlled, as immobilized patients with hematomas rapidly develop a prothrombotic state 1

Common Pitfalls to Avoid

• Do not mistake this for deep vein thrombosis, as anticoagulation would worsen the hematoma 3, 5
• Do not delay evaluation for compartment syndrome, as progressive pain at rest after blunt trauma should raise immediate concern 2
• Do not ignore the possibility of myositis ossificans, which can develop from calcification of the hematoma if initial injury is not properly managed 6
• Do not apply excessive compression that could occlude venous outflow and paradoxically worsen the situation 7
