Multiple hereditary exostoses (MHE) is a genetically conditioned disease characterized by the presence of numerous cartilaginous and bony outgrowths, known as exostoses, on various bones. These hard, palpable nodules commonly occur in the upper and lower limbs, as well as in the pelvis, scapulae, and ribs, with the number, size, and distribution varying among individuals. Multiple hereditary exostoses not only directly damage the joints, affecting bone length and shape, but also limit mobility through bone shortening, bending, and deformities.

Treatment of Multiple Hereditary Exostoses

Individuals with MHE often experience limb length discrepancy, with the femur being affected twice as often as the tibia. Multiple hereditary exostoses can cause deformities such as bowing or knock-knees. Corrective procedures for these deviations include hemiepiphysiodesis, which involves the partial blockade of the growth plate to control further growth. In cases of more advanced axis abnormalities and in adult individuals, limb lengthening and angle correction using an external fixator may be employed. Surgical removal of exostoses can be helpful in addressing ankle joint issues, while problems with the femur can be treated through femoral osteotomy (bone cutting) or by removing exostoses from the femoral neck.

At the Paley European Institute, pediatric orthopedics is conducted at an exceptionally high level. Our patients receive treatments performed by specialists trained by the renowned Dr. Dror Paley, known worldwide. This ensures not only accurate diagnosis of multiple hereditary exostoses but also highly effective treatment options.
