Arthroscopic Excision of Acetabular Osteoid Osteoma: Computer Tomography-Guided Approach.

摘要: Osteoid osteoma is a benign osteoblastic tumor that occurs in the subcortical shaft and metaphysis of long bones lower extremities; however, intra-articular lesions are also possible. Intra-articular osteoid osteomas rare, clinical symptoms often less specific and, thereby, may lead to misdiagnosis. The definitive treatment for excision nidus. We present case 23-year-old man with 4-year history right anterior hip pain, subsequently diagnosed subarticular located acetabulum. Hip arthroscopic juxta-articular presented as an effective treatment, advantage potential damage normal bone cartilage, well additional benefits available arthroscopy.
