Abstract :
Osteoid osteoma near the joints is a rare case which is difficult
to diagnose. Osteoid osteomas refer to solitary, benign, agonizing
lesions of the bone with a nidus of 1.5 to 2 cm, which consists of
osteoid, osteoblasts, and varying quantity of fibrovascular stroma. This
study reports the case of 37-year-old man with a painful flexion
contracture of left elbow for 18 months, then was diagnosed a
peri-articular osteoid osteoma. Any attempt for movement, whether
passive or active, exacerbated the pain. His conditions was treated as
tennis elbow and treated for several months, but his pain persisted
continuously. A subcortical osteoid osteoma was observed in fine-cut CT
scan within the posterior cortex of the capitulum. Thus, a wide en bloc
surgical excision of the nidus was implemented, with total mitigation of
pain and quick return to daily activities. It is stressed that history
of disease and detailed physical examination can help diagnosis.
