Limb Lengthening Surgery and Sleep: Melatonin, Sleep Hygiene and Bone Remodeling
Limb Lengthening Surgery and Sleep Melatonin • Sleep Hygiene • Bone Remodeling
Sleep quality is a silent but powerful driver of recovery after limb lengthening surgery.
Melatonin, sleep hygiene and deep rest directly
influence bone remodeling, pain perception and overall motivation.

Introduction
Recovery after limb lengthening surgery is not only about distraction rate or physiotherapy.
Sleep acts as a hidden cornerstone of healing. During deep sleep, melatonin, growth hormone
and IGF-1 peak, accelerating mineralization of the regenerate bone. Poor sleep, on the other hand,
can prolong consolidation and device time.
Melatonin’s Role
Known as the “night hormone”; rises in darkness and synchronizes circadian rhythm.
Supports osteoblast activity while suppressing osteoclasts, promoting bone formation.
Disrupted by smoking, high caffeine intake, late-night screen exposure or night-shift work.
In selected cases, short-term melatonin supplementation may be considered with medical guidance.
Sleep Hygiene
Consistent schedule: Go to bed and wake up at the same times daily.
Dark and cool environment: Essential for melatonin secretion and deep rest.
Screen detox: Stop phone/TV/tablet use at least 1 hour before bedtime.
Avoid stimulants: Limit caffeine, nicotine and heavy meals in the evening.
Routine: Warm shower, stretching or breathing exercises can improve sleep onset.
Sleep and Bone Remodeling
The regenerate: Newly formed bone during distraction is weak at first.
Deep sleep window: Growth hormone and IGF-1 release accelerates mineralization.
Good sleep: Faster corticalization, potentially earlier device removal.
Psychology & Pain
Insufficient sleep lowers pain threshold and worsens mood. Quality sleep reduces pain perception,
strengthens mental resilience and boosts participation in physiotherapy, which is vital for long-term function.
Practical Tips
Aim for 7–9 hours of quality night sleep; naps cannot fully compensate.
Ensure proper pain management and comfortable positioning with pillows.
Discuss melatonin or magnesium supplements with your doctor if insomnia persists.
Seek professional help for chronic insomnia or sleep apnea.
Conclusion
In limb lengthening surgery, sleep is the silent ally of recovery.
Melatonin balance and good sleep hygiene improve bone remodeling, pain tolerance and motivation.
Surgeons should consider sleep quality alongside distraction rate and physiotherapy during follow-up.
