Keyhole resection of intra-articular osteoid osteoma in the ulnar trochlear notch using 3-dimensional computed tomography-based navigation

Osteoid osteoma is a relatively common benign bone tumor that mainly occurs in the long bones and is characterized by nocturnal pain that is improved by nonsteroidal anti-inflammatory drugs (NSAIDs). However, intra-articular osteoid osteomas are rare, with an incidence of approximately 13% of osteoid osteomas.2 Intra-articular osteoid osteomas sometimes present with symptoms similar to monoarticular inflammatory arthritis, such as joint tenderness, soft-tissue swelling, synovitis, and joint effusion, which may lead to misdiagnoses or treatment delays.
