Leg Lengthening Surgery: Comprehensive Risk Overview

Potential Complications of Limb Lengthening

Leg lengthening (distraction osteogenesis) is a complex orthopedic procedure with significant risks:

• Infection: Pin‑site or deep infection; can progress to sepsis.
• Bleeding: Intra‑ or postoperative hemorrhage requiring transfusion.
• Deep Vein Thrombosis (DVT): Risk of pulmonary embolism.
• Nerve Injury: Pain, numbness, weakness, or paralysis.
• Malunion: Abnormal bone healing causing deformity.
• Nonunion: Failure of bone consolidation; may need revision surgery.
• Compartment Syndrome: Elevated muscle pressure; emergency fasciotomy may be required.
• Mortality: Rare but inherent to major surgery.

Risk Mitigation

Rigorous preoperative assessment, experienced surgical team, meticulous postoperative monitoring, and structured rehabilitation reduce complication rates.
