Chondroblastoma is a rare primary bone tumor that usually affects
the epiphysis or apophysis of long bones, especially the proximal part of the
tibia, the proximal part of the humerus, and the proximal and distal parts of
the femur. Its clinical course is unpredictable, and it can behave
aggressively without treatment. Even with curettage, the local recurrence rate
can be =20% within three years after the
operation1-7.
A few cases of metastasis have been reported despite the histologically benign
appearance of the
tumor5,6.
There have been reports of the development of osteoarthritis of the hip joint
secondary to femoral head collapse after curettage of lesions in the femoral
head2,6.
In this paper, we report the case of a patient with chondroblastoma of the
femoral head and acetabular dysplasia who was treated with rotational
acetabular osteotomy to prevent femoral head collapse after curettage of the
lesion. The patient was informed that data concerning this case would be
submitted for publication.
