Changes in the Appendicular Skeleton with Age

3.2K
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...

Development of the Limb Synovial Joints

2.0K
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.
During development, the limbs...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

3.9K
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...

Area of Science:

  • Hand Surgery
  • Developmental Biology
  • Congenital Anomalies

Background:

  • Thumb anomalies are relatively common, often linked to various syndromes.
  • These congenital conditions manifest as a spectrum from complete absence to polydactyly (duplication).
  • Restoring thumb opposability is a complex yet highly rewarding area within reconstructive hand surgery.

Purpose of the Study:

  • To provide a concise overview of common thumb anomalies.
  • To discuss current and evolving surgical treatment strategies.
  • To illustrate treatment outcomes through selected clinical case examples.

Main Methods:

  • Review of common thumb developmental anomalies.
  • Discussion of established and novel surgical reconstructive procedures.
  • Presentation of illustrative clinical cases.

Main Results:

  • Thumb anomalies encompass a wide range of presentations, requiring tailored surgical approaches.
  • Modified classification systems aid in precise description and treatment planning.
  • Advancements in surgical techniques are continuously improving functional outcomes for patients.

Conclusions:

  • Reconstructive surgery for thumb anomalies is a challenging but essential component of hand surgery.
  • Ongoing evolution of surgical concepts and procedures enhances the functionality of affected hands.
  • Effective management relies on accurate classification and appropriate application of surgical techniques.
