Case Reports in Orthopedics
|December 20, 2014
Summary
A rare case highlights how hypertrophic nonunion of the humerus can mimic enchondroma on initial imaging. Further evaluation and histopathology confirmed the nonunion, presenting a unique diagnostic challenge.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Oncology
- Radiology
Background:
- Humeral shaft fractures typically heal well with conservative treatment.
- Nonunion, though infrequent, can occur following humeral shaft fractures.
- Enchondromas are common benign bone tumors often discovered incidentally.
Purpose of the Study:
- To report a unique case of hypertrophic nonunion of the humerus.
- To illustrate the diagnostic challenge posed by a nonunion mimicking an enchondroma.
- To emphasize the importance of thorough evaluation in differentiating bone lesions.
Main Methods:
- Case report of a young male patient.
- Initial radiographic assessment.
- Histopathological analysis for definitive diagnosis.
Main Results:
- Initial X-rays suggested an enchondroma.
- Histopathological examination confirmed a 1.5-year-old hypertrophic nonunion of the humerus.
- The case presented a significant diagnostic dilemma.
Conclusions:
- Hypertrophic nonunion of the humerus can present with imaging findings similar to enchondromas.
- Accurate diagnosis requires careful clinical correlation and often histopathological confirmation.
- This case underscores the importance of considering differential diagnoses in bone lesion interpretation.

01:19Bones of the Upper Limb: Humerus
14.8K
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...

01:24Bone Formation by Endochondral Ossification
16.1K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

01:15Bones of the Upper Limb: Ulna
11.2K
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...

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

01:27Growth of Cartilage and Bone Tissue
5.0K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

01:09Bones of the Upper Limb: Radius
11.7K
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...
