Summary
Fish offer a valuable, yet overlooked, model for studying spinal deformities like idiopathic scoliosis. Their genetic tractability and diverse, non-induced vertebral defects provide new avenues for understanding spinal health.
Area of Science:
- Developmental biology
- Comparative anatomy
- Genetics
Background:
- Vertebral development is complex, with defects like idiopathic scoliosis affecting 2-3% of humans.
- Current animal models for skeletal defects lack non-induced deformities and experimental tractability.
- Fish share many vertebral integrity challenges with humans but are underutilized in research.
Purpose of the Study:
- To review spinal curvature in teleosts (fish).
- To propose teleosts as an unexploited resource for studying vertebral stability, deformity, development, and genetics.
- To highlight the potential of fish models for understanding idiopathic scoliosis etiology and treatment.
Main Methods:
- Review of existing literature on spinal curvature in teleosts.
- Comparison of teleost vertebral development and deformities with human conditions like idiopathic scoliosis.
- Analysis of the advantages of fish models, including tractability, diverse deformities, and genomic resources.
Main Results:
- Teleosts exhibit common morphological deformities during spinal development, including curvature.
- Fish possess significant genetic resources and are amenable to experimental manipulation.
- The absence of an appendicular skeleton in fish allows for focused analysis of spinal integrity.
Conclusions:
- Teleosts represent a valuable, tractable model for investigating the fundamental aspects of vertebral development and deformity.
- Fish models can significantly contribute to identifying causes, risk factors, and potential treatments for human spinal conditions such as idiopathic scoliosis.
- Further research utilizing teleosts is recommended to advance the understanding of spinal health and disease.

Vertebral 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...

General Structure of a Vertebra
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.
Articulations of the Vertebral Column
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...
Muscles of the Vertebral Column
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...
