Bottom Line: Three radiological indices were used for evaluating the results: an external fixation index, a distraction index, and a maturation index.The mean length of distraction was 7.3 cm (range, 5.1 to 12.1 cm).The mean external fixation index was 26.0 day/cm (range, 19.8 to 32.5 day/cm), the distraction index was 9.6 day/cm (range, 6.8 to 12.0 day/cm), and the maturation index was 14.9 day/cm (range, 8.0 to 22.5 day/cm).

ABSTRACT

Background: The aim of this study was to assess the results of using the Ilizarov apparatus to transport bones in the treatment of benign bone tumors.

Methods: Seven patients (six males and one female) with benign bone tumors were treated by bone transport with an Ilizarov apparatus at our institution. Their mean age at surgery was 14.4 years (range, 4.8 to 36.9 years). The histological diagnoses were osteofibrous dysplasia (4), giant-cell tumor (1), intraosseous cavernous hemangioma (1), and aneurysmal bone cyst (1). Three radiological indices were used for evaluating the results: an external fixation index, a distraction index, and a maturation index. The bone and functional results were evaluated according to the Association for the Study and Application of the Method of Ilizarov classification.

Results: Five patients had bone union at the reconstructed site, one patient had a local recurrence, and the other had a nonunion at the docking site. The mean length of distraction was 7.3 cm (range, 5.1 to 12.1 cm). The mean external fixation index was 26.0 day/cm (range, 19.8 to 32.5 day/cm), the distraction index was 9.6 day/cm (range, 6.8 to 12.0 day/cm), and the maturation index was 14.9 day/cm (range, 8.0 to 22.5 day/cm). Ultimately, the bone and the functional results were rated excellent in six cases and good in one case.

Conclusions: Bone transport using the Ilizarov apparatus is a good treatment option in patients with bone defects after the resection of an active or aggressive benign bone tumor.

The histological diagnosis was giant cell tumor. (C) Lengthening was done at proximal from the docking site. (D) Docking site and distracted bone union was achieved.

Mentions: The mean length of the defect after tumor resection was 7.3 cm (range, 5.1 to 12.1 cm) and the mean defect ratio was 22.1% (range, 12.9% to 52.4%), which is shown in Table 1. The length of distraction was determined by the patient's age, bone age, and unaffected limb length. The mean length of distraction was 6.9 cm (range, 4.9 to 11.0 cm). The external fixation was applied at 185.6 days (range, 106 to 266 days). The mean external fixation index was 26.0 day/cm (range, 19.8 to 32.5 day/cm), the distraction index was 9.6 day/cm (range, 6.8 to 12.0 day/cm) and the maturation index was 14.9 day/cm (range, 8.0 to 22.5 day/cm) (Table 3). All the patients were able to perform their daily activities without problems. The bone and functional results were rated excellent in six cases and good in one case. The radiographs of representative cases are shown in Figs. 1,2,3.
