Avoid routine early surgical exploration for primary RNP
EMG/NCS at 9 weeks guides further management
Pathological fracture principles
Treatment of underlying malignancy primary goal
Prophylactic intramedullary nail or ORIF for impending or complete pathological fractures
Radiation therapy for radiosensitive tumors after fixation
Osteoporosis secondary prevention
Proximal and middle third fractures in older adults classified as fragility fractures
Calcium, vitamin D, and bisphosphonate therapy reduce future fracture risk
DEXA scan and endocrinology or rheumatology referral appropriate
Patient Discharge Instructions
copy discharge instructions
Humerus fracture home care instructions
Keep the splint or brace in place as instructed
Do not remove, modify, or get the splint wet
Keep the arm elevated when possible to reduce swelling
No lifting, carrying, pushing, or pulling with the injured arm for at least 6 weeks
Pain and medication instructions
Acetaminophen and ibuprofen as directed for pain control
If prescribed opioids, take only as needed and do not drive
Do not drink alcohol while taking opioid medications
Follow-up instructions
Orthopedic appointment within 7-10 days is essential
Repeat X-rays will be taken to confirm the bone is in acceptable position
At that visit, the splint may be converted to a removable functional brace
Physical therapy will begin to restore shoulder and elbow movement
Warning signs to return to the emergency department immediately
New or worsening numbness, tingling, or weakness in the hand or fingers
Inability to extend the wrist or fingers (wrist drop)
Increasing pain not controlled by medications
Swelling that is rapidly worsening or the skin feels very tight
Any open sores, wound drainage, or smell from the splint area
Fever above 38.5 degrees Celsius
Loss of pulse or color change in the hand (pale, blue, cold)
Brace or splint becoming very loose with visible new deformity
Activity and recovery expectations
Most patients with closed fractures heal over 10-12 weeks
Full functional recovery may take 3-6 months
Attend all scheduled physical therapy and follow-up appointments
Contact orthopedic office if you have concerns between appointments
Bone health for elderly patients
Calcium-rich diet and vitamin D supplementation as directed
Discuss osteoporosis screening with your family doctor
Fall prevention strategies: grab bars, non-slip mats, appropriate footwear
