Earlier return to function compared to cast immobilization
Lower rates of malunion compared to percutaneous pinning
Allows early mobilization reducing stiffness and CRPS risk
Cotton-Loder position avoidance
Palmar flexion immobilization historically used for Smith fractures
Precipitates median nerve neuropathy by increasing carpal tunnel pressure
Orthopedic Clinics of North America 2022: avoid prolonged palmar flexion positioning
Current standard: dorsiflexion and supination for splinting
Long-term outcomes
Most patients regain functional wrist motion by 3-6 months
Grip strength recovery may take up to 12 months
Post-traumatic arthritis risk increases with intra-articular involvement
Complex regional pain syndrome occurs in approximately 2-5% of distal radius fractures
Patient Discharge Instructions
copy discharge instructions
Diagnosis and overview
Smith fracture: broken wrist bone (radius) with the broken piece shifted toward the palm side
Requires careful follow-up to ensure the bone heals in correct position
Splint and cast care
Keep splint or cast clean and dry at all times
Cover with a plastic bag for showering
Do not insert objects under splint to scratch
Do not remove or modify splint
Elevate hand and wrist above heart level when resting to reduce swelling
Ice pack (wrapped in cloth) to wrist for 20 minutes several times daily for first 48 hours
Pain management
Acetaminophen 650-1000 mg every 6-8 hours as needed for pain
Ibuprofen 400-600 mg with food every 6-8 hours if no contraindications
Prescribed opioid pain medication only for severe pain not controlled by above
Do not drive or operate machinery while taking opioid medications
Finger exercises
Wiggle all fingers regularly throughout the day to reduce stiffness
Full fist and finger straightening exercises unless splint prevents it
Follow-up instructions
Orthopedic or hand surgery follow-up within 5-7 days
Repeat x-rays will be done at follow-up to confirm bone alignment
Additional x-rays at 2 weeks after injury
Return to emergency department immediately for
Increasing numbness or tingling in thumb, index, or middle finger
Increasing pain not controlled by medication
Pain when straightening fingers passively
Fingers turning blue, white, or cold
Inability to move fingers
Splint feels too tight or is cutting into skin
Fever, drainage, or foul smell from splint area
Visible skin breakdown or pressure sores under splint
Recovery expectations
Swelling and bruising expected to worsen for first 48-72 hours then improve
Functional wrist motion expected to return by 3-6 months
Grip strength recovery may take up to 12 months
Bone healing typically occurs in 6-8 weeks with proper immobilization
