Bone Transport for Reconstruction in Benign Bone Tumors

Area of Science:

• Orthopedic Surgery
• Oncology
• Biomedical Engineering

Background:

• Benign bone tumors can necessitate surgical intervention leading to bone defects.
• The Ilizarov apparatus is a well-established external fixation device used in orthopedic reconstruction.

Purpose of the Study:

• To evaluate the efficacy of the Ilizarov apparatus for bone transport in treating benign bone tumors.
• To assess bone union, functional outcomes, and radiological indices following Ilizarov-assisted bone transport.

Main Methods:

• Seven patients with benign bone tumors underwent bone transport using the Ilizarov apparatus.
• Histological diagnoses included osteofibrous dysplasia, giant-cell tumor, hemangioma, and aneurysmal bone cyst.
• Radiological indices (external fixation, distraction, maturation) and Association for the Study and Application of the Method of Ilizarov (ASAMI) criteria were used for evaluation.

Main Results:

• Successful bone union was achieved in five patients; one experienced recurrence, and another had nonunion.
• Mean distraction length was 7.3 cm.
• Six cases were rated excellent and one good for bone and functional results based on ASAMI criteria.

Conclusions:

• Bone transport with the Ilizarov apparatus is a successful treatment for bone defects resulting from benign bone tumor resection.
• The Ilizarov technique offers a favorable option for limb reconstruction and defect management in this patient cohort.
