Summary
Osteoid osteoma, a benign bone tumor, can occur in the hand, presenting with vague symptoms. Early CT diagnosis and surgical removal of the nidus effectively resolved wrist pain and swelling in a teenage patient.
Area of Science:
- Orthopedic Surgery
- Radiology
- Pediatric Oncology
Background:
- Osteoid osteoma is a benign bone-forming tumor, typically affecting long bones, but rarely found in the hand.
- Nonspecific initial symptoms can delay diagnosis, leading to prolonged patient suffering and misdiagnosis.
Observation:
- A 14-year-old male presented with two months of spontaneous wrist swelling and pain.
- Initial radiography showed a sclerotic lesion in the scaphoid bone, with normal sedimentation rate, prompting suspicion of other conditions like tuberculosis.
- A computed tomography (CT) scan of the wrist revealed the characteristic double-ring sign, pathognomonic for osteoid osteoma.
Findings:
- The osteoid osteoma nidus within the scaphoid bone was surgically excised via curettage.
- Post-operative recovery was marked by rapid and complete resolution of the patient's wrist pain and swelling.
Implications:
- This case highlights the importance of considering osteoid osteoma in the differential diagnosis of wrist pain, even with atypical localization.
- Advanced imaging, particularly CT scans, is crucial for accurate diagnosis of osteoid osteoma by visualizing the double-ring sign.
- Surgical excision of the nidus provides an effective and curative treatment for symptomatic osteoid osteomas in the hand, leading to excellent functional outcomes.

Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
Compact Bone
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bones 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...
Bones 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...
Bones 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...

Changes in the Appendicular Skeleton with Age
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
