ABSTRACT

Osteoid osteoma (OO) is a benign bone-forming tumor, it affects all age groups and especially young adults. Bones of lower extremity are predominantly involved. The proximal femur is involved in 20% of cases. Pain tends to become increasingly severe at night and is relieved by salicylates. Lesions involving the articulating surfaces are commonly associated with synovitis. When the tumor is clinically suspected, X-rays and Computed Tomography (CT) practically confirm the diagnosis but also specify the location of the lesion. Sought treatment for osteoid osteoma of the proximal femur should be simple, accurate, efficient and inexpensive as possible. We report 04 cases of articular and juxta-articular OO of the proximal femur, all treated by open surgery with very good evolution.
