Preserve radial head whenever possible — critical for longitudinal stability
Radial head transmits approximately 60% of axial load through forearm
Excision causes proximal radial migration and wrist instability
Arthroplasty preferred over excision when head not reconstructable
Maintains radial length and lateral elbow stability
Modular implant sizing critical for kinematics
Patient Discharge Instructions
copy discharge instructions
Monteggia fracture home care after splinting or casting
Keep the splint or cast dry and intact at all times
Waterproof cover for bathing
Do not insert objects inside the cast to scratch the skin
Elevate the arm above heart level when resting
Reduces swelling for the first 48 to 72 hours
Prop on pillows when sleeping
Ice pack over the cast for 20 minutes every 2 hours for the first 2 days
Do not place ice directly on skin
Protect with a towel
Pain medications as prescribed
Take with food to avoid stomach upset
Do not drive or operate machinery if taking opioid pain medication
Activity restrictions
No weight-bearing on the injured arm until cleared by orthopedics
No lifting, pushing, or pulling with the injured arm
Use the other arm for daily activities
Return to work and sport restricted until follow-up assessment
Expect 6 to 12 weeks minimum immobilization and recovery for most cases
Adult operative cases may require 3 to 6 months for return to heavy work
Warning signs to return to the emergency department immediately
Increasing pain or pressure inside the cast not relieved by elevation and ice
Severe tightness or pressure sensation in the forearm
Burning or crushing pain — compartment syndrome warning
Numbness or tingling in the hand or fingers
Inability to move the fingers
Hand appears pale, blue, or cold
Fever above 38.5 degrees Celsius with an open wound or surgery site
Drainage, redness, or increasing warmth around any wound
Foul odor from cast or splint
The cast or splint cracks, breaks, or becomes loose
Follow-up instructions
Orthopedic appointment within 5 to 7 days — mandatory
Bring all imaging taken at the emergency department
Bring a list of all current medications
Expect repeat X-rays at every follow-up visit to confirm healing alignment
Report any change in the feel of the arm between visits
Physiotherapy or occupational therapy referral likely after cast removal
Range of motion and strengthening exercises are essential for full recovery
