Abstract
Background. The Ilizarov method is a recognized technique for treating severe skeletal injuries, allowing for a comprehensive restoration of both bone and soft tissue components. Despite the fact that bone lengthening and transport are widely known techniques, distraction of a longitudinally split fragment is still used extremely rarely.
The aim of the study is to describe a series of clinical cases involving patients operated on using this technique.
Methods. We present a series of observations of five patients who underwent distraction of a longitudinally split fragment using the Ilizarov method between January 2006 and December 2022. Clinical information was obtained from case histories, all surgical interventions were documented. Postoperative examination was performed using radiography.
Results. A case series demonstrates the successful application of this technique for reconstruction of partial bone defects resulting from trauma or osteomyelitis. The study included five patients (4 men and 1 woman) who underwent surgery 4.8-34.0 months after trauma for a partial defect of the proximal tibia ranging from 4 to 8 cm in length. Distraction was performed in different directions along the sagittal and longitudinal axes. The time of external fixation ranged from 3.5 to 4.8 months, the external fixation index ranged from 0.49 to 1.22. The ASAMI (Association for the Study and Application of the Methods of Ilizarov) functional score at the follow-up examination was excellent in all five patients. The ASAMI bone tissue assessment showed excellent results in all patients, except for one patient with residual equinus (good result). No other complications were reported.
Conclusions. The Ilizarov method provides a minimally invasive and comprehensive approach to the elimination of partial bone defects, affecting simultaneously the skeletal and soft tissue components. Due to the longitudinal splitting during fragment transport and distraction osteogenesis, this method promotes bone and tissue regeneration and helps to avoid a volumetric bone defect and more complex segmental bone transport. Moreover, the role of transverse transport of the tibial cortex increases in the treatment of peripheral arterial diseases.
