Changes in the Appendicular Skeleton with Age01:09

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 Joints01:07

Development of the Limb Synovial Joints

4.9K
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...

Nature and Nurture01:10

Nature and Nurture

19.4K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

14.7K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Signs of Puberty01:27

Signs of Puberty

2.1K
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...

    Area of Science:

    • Orthopedic surgery
    • Limb reconstruction
    • Biomedical engineering

    Background:

    • Limb lengthening procedures are critical for addressing discrepancies and deformities.
    • Traditional methods can have limitations in achieving significant length gains and functional restoration.
    • The development of advanced external fixation systems is essential for improving surgical outcomes.

    Discussion:

    • The study compared two surgical techniques: distraction of the growth epiphysis and diaphyseal-metaphyseal corticotomy.
    • Both techniques utilized a novel lineal and T-shaped external fixator system with a triplanar system.
    • The fixator's versatility as a neutralizer, distractor, compressor, or bone carrier was highlighted.

    Key Insights:

    • The novel external fixator system enabled substantial limb lengthening, averaging 6 cm and up to 18 cm.
    • Anatomical and functional results confirmed the method's efficiency in limb lengthening.
    • The triplanar system integrated into the fixator facilitated precise multi-directional bone manipulation.

    Outlook:

    • Further research could explore long-term outcomes and patient-reported functional improvements.
    • Potential for wider adoption of this versatile external fixator in complex orthopedic cases.
    • Investigating modifications to the fixator for specific pediatric and adult limb lengthening scenarios.
