Area of Science:

  • Orthopedic Surgery
  • Biomechanical Engineering

Background:

  • Limb-lengthening surgery is complex with a high initial complication rate.
  • Experience and procedural modifications are crucial for improving outcomes.

Purpose of the Study:

  • To analyze complication rates in the initial 80 limb-lengthening procedures.
  • To identify factors contributing to the reduction of complications with surgical experience.

Main Methods:

  • Review of 80 consecutive limb-lengthening procedures using circular or unilateral external fixators.
  • Analysis of complication incidence and correlation with surgical experience and protocol changes.

Main Results:

  • Initial complication rate of 100% significantly decreased with experience (P < .01).

  • Specific interventions reduced axial deviation, delayed consolidations, fractures, pin-track infections, muscle contractures, and joint subluxation.

    • Conclusions:

    • Surgical experience and systematic protocol refinements significantly reduce complications in limb-lengthening procedures.
    • Targeted strategies for fixator configuration, bone grafting, infection control, and pain management are effective.
