Summary
Spine implants can alter growth plate structure. This study found that implant proximity reduced hypertrophic zone height and chondrocyte size in growth plates, impacting spinal growth.
Area of Science:
- Orthopedics
- Developmental Biology
- Spinal Surgery
Background:
- Growth plate compression is linked to structural changes.
- Spinal implants are used to modulate spinal growth.
Purpose of the Study:
- To investigate the relationship between spine implant distance and physeal hypertrophic zone height and chondrocyte size.
- To understand how asymmetric growth modulation affects growth plate morphology.
Main Methods:
- Evaluating the height of physeal hypertrophic zones and chondrocyte dimensions (height and width).
- Measuring these parameters at varying distances from a spine implant in stapled vertebrae.
- Assessing changes 8 weeks postoperatively.
Main Results:
- Hypertrophic zone height, cell height, and cell width decreased across the coronal plane of the growth plate.
- The most significant reductions were observed directly underneath the spine implant.
- These changes indicate an inhibitory effect of the implant on growth plate activity.
Conclusions:
- Proximity to a spine implant directly correlates with reduced growth plate height and chondrocyte size.
- Asymmetric growth modulation by implants leads to localized structural changes in the growth plate.
- Findings provide insight into the biomechanical effects of spinal implants on pediatric spinal growth.

01:09Changes in the Appendicular Skeleton with Age
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...

01:24Bone Formation by Endochondral Ossification
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...
01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:07Development of the Limb Synovial Joints
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.

01:27Signs of Puberty
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)...
01:16Vertebral Column: Regions and Curvature
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...
