Summary
This case study describes a rare condition of bilateral second carpal row duplication, a previously undocumented wrist anomaly. The 75-year-old patient exhibited 18 carpal bones in each wrist, a significant finding in skeletal research.
Area of Science:
- Orthopedics and skeletal biology.
- Medical imaging and diagnostics.
- Genetics and rare diseases.
Background:
- The patient had a history of childhood diagnoses for Marfan syndrome and Ehlers-Danlos syndrome, though lacking definitive evidence or follow-up.
- She experienced lifelong articular symptoms suggestive of multiple epiphyseal dysplasia, necessitating knee and hip surgeries.
Observation:
- A 75-year-old woman presented with pain at the base of her left fifth metacarpal bone.
- Radiographic and computed tomography (CT) imaging revealed bilateral duplication of the second carpal bone row.
Findings:
- The patient presented with a unique, previously undescribed condition of bilateral second carpal row duplication.
- Each wrist contained a total of 18 carpal bones, a significant deviation from the typical anatomy.
Implications:
- This finding expands the known spectrum of carpal bone anomalies and congenital wrist conditions.
- Highlights the importance of thorough skeletal evaluation, even in patients with presumed connective tissue disorders.
- Provides a unique case for studying carpal development and potential genetic influences on skeletal morphology.

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...

01:17Structural Joints: Cartilaginous Joints
4.9K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

01:07Development of the Limb Synovial Joints
2.7K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

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...

01:15Bones of the Upper Limb: Ulna
10.6K
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...

01:49Meiosis I
221.8K
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by...
