Pathophysiology of Joints
Developmental Defects and Congenital Skeletal Anomalies
Ollier's Disease (Multiple Enchondromatosis)

The condition is described as dyschondroplasia. It is characterized by the sporadic appearance of multiple foci of hyaline Cartilage that replace normal areas in the metaphyses and diaphyses of bones. These bone lesions may occur unilaterally or bilaterally, but are distributed asymmetrically (Ollier L., 1899). Unilateral growth in long bones leads to angular deformity. Radiographically, intraosseous cartilaginous nodules are identified in typical locations within the abnormal areas (Fig. 53).

Malignant transformation in Ollier's disease is extremely rare. Corrective osteotomies are used to correct angular deformities. Pathological fractures in the area of cartilaginous nodules are treated using conventional Methods, though secondary post-traumatic deformities occasionally occur.

Treatment involves radical Curettage of the cartilaginous lesions or bone resection with their removal, followed by bone grafting to fill the defects.
