Background
Hereditary multiple exostoses (HME) is a genetic disorder that causes limb deformities due to disturbance at the growth plates.
Materials and methods
Six adolescents, whith symptomatic valgus deformity at the ankle and knee (seven affected legs) underwent correction procedures
using the Ilizarov apparatus. In 5 legs, a bifocal Ilizarov apparatus was used, whereas in 2 legs the use of a monofocal apparatus
was sufficient.
Results
Correction of the mechanical axis was achieved in all cases, and limb length discrepancy was equalized in the 3 cases that
underwent limb elogation. The average knee and ankle corrections were 15° and 18°, respectively. The average time from application
to removal of the Ilizarove apparatus was 4.6 months. No major complication occurred.
Conclusions
The use of the Ilizarov method in adolescents with HME enables successful simultaneous correction of multiplanar, multifocal
complex limb deformities.
