Summary
Intra-articular osteoid osteoma, a rare bone tumor, can mimic inflammatory arthritis, leading to delayed diagnosis. This case highlights the diagnostic challenges of osteoid osteoma presenting as resistant monoarthritis in an adolescent.
Area of Science:
- Orthopedics
- Pediatric Rheumatology
- Musculoskeletal Oncology
Background:
- Intra-articular osteoid osteoma (OO) is an uncommon benign bone tumor.
- Diagnosis can be challenging due to nonspecific symptoms and location within the joint.
Observation:
- An 11-year-old boy presented with persistent, treatment-resistant inflammatory monoarthritis of the left elbow.
- Initial symptoms were misattributed to arthritis, potentially influenced by a preceding wart ablation in the same area.
Findings:
- The patient was ultimately diagnosed with an intra-articular osteoid osteoma.
- Late diagnosis occurred because the osteoid osteoma symptoms were initially suggestive of arthritis.
Implications:
- This case underscores the importance of considering osteoid osteoma in the differential diagnosis of refractory pediatric monoarthritis.
- Early and accurate diagnosis of intra-articular osteoid osteoma is crucial for effective management and preventing long-term joint damage.

01:19Bones of the Upper Limb: Humerus
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

01:23Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
