Range of motion exercises starting at 4 to 6 weeks
Strengthening program from 6 to 8 weeks
Return to activity timelines
Light activities at 6 to 8 weeks
Full return to contact sport or manual labor at 3 to 6 months
Prevention of long-term complications
Anatomic reduction reduces arthritis risk
Not all patients with arthritis become symptomatic
Functional rehabilitation key regardless of radiographic outcome
First web space maintenance
Thumb abduction exercises prevent adduction contracture
Splinting in abduction position during immobilization
Patient Discharge Instructions
copy discharge instructions
Bennett fracture home care instructions
Keep the thumb spica splint clean and dry
Do not remove the splint unless instructed by your doctor
Use a plastic bag or waterproof cover when showering
Elevate the hand above heart level as much as possible
Reduces swelling and pain
Especially important for the first 48 to 72 hours
Apply ice wrapped in a cloth for 20 minutes every 2 to 3 hours
Do not apply ice directly to skin
Continue for first 48 hours
Pain management at home
Take ibuprofen 400 to 600 mg with food every 6 to 8 hours as needed
Maximum 2400 mg per day
Avoid if kidney problems or stomach ulcer history
Take acetaminophen 500 to 1000 mg every 6 hours as needed
Maximum 4 g per 24 hours
Do not combine with other acetaminophen-containing products
Use both medications together for better pain control if needed
Alternate on a schedule rather than waiting for severe pain
