Cardiomyopathy III: Hypertrophic Cardiomyopathy

Cardiomyopathy III: Hypertrophic Cardiomyopathy

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...

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy I: Introduction and Classification

Cardiomyopathy, or CMP, is a group of diseases affecting the myocardial structure, impairing its ability to pump blood effectively. This condition can lead to arrhythmias, heart failure, or sudden cardiac death.Cardiomyopathies are classified into primary and secondary categories:Primary Cardiomyopathy refers to conditions involving only the heart muscle that are often idiopathic (of unknown cause) or genetic. They primarily affect the myocardium without the involvement of other systemic...

Muscles of the Forearm that Move the Hand and Fingers

Muscles of the Forearm that Move the Hand and Fingers

The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

Cystic Fibrosis: Pathogenesis

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Summary

A rare carpal dislocation in a child mimicked Madelung deformity. Magnetic resonance imaging (MRI) clarified the diagnosis by visualizing unossified carpal centers, aiding treatment decisions.

Area of Science:

Orthopedics
Pediatric Radiology
Medical Imaging

Background:

Madelung deformity is a rare condition affecting wrist development.
Diagnosing wrist deformities in young children can be challenging due to unossified carpal bones.

Observation:

A 4-year-old boy presented with a wrist deformity clinically resembling Madelung deformity.
Standard radiographs were inconclusive due to the lack of ossification in the carpal bones.

Findings:

Magnetic resonance imaging (MRI) proved diagnostic by clearly delineating the cartilaginous ossification centers of the carpus.
The findings indicated a chronic carpal dislocation rather than a true Madelung deformity.

Implications:

Chronic carpal dislocation should be considered in the differential diagnosis of pediatric wrist deformities.
Advanced imaging like MRI is crucial for accurate diagnosis when radiographs are limited by skeletal immaturity.
This case highlights the importance of considering alternative diagnoses in complex pediatric orthopedic presentations.
