Management of Bone Defects and Complications After Bone Tumor Resection Using Ilizarov Method

Area of Science:

• Orthopedic Surgery
• Oncology
• Biomedical Engineering

Background:

• Complex orthopedic challenges often require advanced reconstructive techniques.
• Distraction osteogenesis using the Ilizarov method offers a solution for significant bone defects.
• Managing bone tumors in the lower extremity presents unique challenges in limb salvage and reconstruction.

Purpose of the Study:

• To evaluate the clinical experience with distraction osteogenesis for lower extremity bone tumors.
• To assess the efficacy of the Ilizarov method in managing composite bone defects and complications.
• To analyze functional outcomes and healing status following Ilizarov-based tumor reconstruction.

Main Methods:

• Retrospective analysis of 11 patients treated with Ilizarov distraction osteogenesis (2010-2020).
• Inclusion of epiphyseal distraction, bone transport, and external fixation for sarcoma treatment and complications.
• Assessment of clinical data including defect location, bone healing, and limb function (MSTS, ASAMI scores).

Main Results:

• Average bone defect reconstruction of 13 cm in 11 patients (mean follow-up 66 months).
• Successful epiphyseal distraction in 3 young children; 7 patients managed postoperative complications.
• High rates of excellent/good ASAMI bone and function scores (63.6% and 90.9% respectively) in 10/11 patients.

Conclusions:

• The Ilizarov method is clinically valuable for resection and reconstruction of lower extremity bone tumors.
• This technique effectively addresses complex postoperative complications, including infection and bone defects.
• Ilizarov distraction osteogenesis facilitates successful limb salvage and functional restoration in challenging cases.
