Insights
Research on spinal and chest wall deformities highlights the need for more evidence-based studies. Current treatments lack robust data due to rare and heterogeneous conditions affecting spinal growth.
Area of Science:
- Pediatric Orthopedics
- Thoracic Surgery
- Developmental Biology
Background:
- Knowledge of spinal, chest wall, and lung growth in normal and deformity states has evolved across specialties.
- Interdisciplinary interest has grown with advancements in assessment and treatment tools.
- Emergence of spine-based, chest wall-based, resection, and gradual distraction treatment options.
Purpose of the Study:
- To review research on the growth of the spine and chest wall.
- To examine the treatment of associated deformities.
- To contextualize findings within evidence-based assessment frameworks.
Main Methods:
- Systematic review of peer-reviewed research on spinal, lung, and chest wall growth and deformity treatment.
- Comparison of various treatment modalities and their outcomes.
- Assessment and ranking of evidence levels where feasible.
Main Results:
- Most studies are Level III or IV (case-control, case series) due to the rarity and heterogeneity of disorders.
- The natural history of most spinal/chest wall deformities is not accurately known.
- Experimental evidence informs some growth-modulating spine treatments, but accurate deformity models are lacking.
- Advancements in imaging and measurement enhance patient comparison capabilities.
Conclusions:
- Significant opportunities exist for further evidence-based research into the natural history and treatment outcomes of spinal and chest wall deformities.
Study Design:
: Review of relevant studies, including levels of evidence.
Objective:
: To review research on growth of the spine and chest wall and treatment of deformities. To place this knowledge in context of evidence-based assessment.
Summary Of Background Data:
: Knowledge of the growth of the spine, chest wall, and lung in the normal and deformity states has evolved among independent specialties over the past 60 years. Interest in the interrelationship has blossomed as more tools for assessment and treatment have developed. Spine-based and chest wall-based treatment options now exist, as well as options of resection versus gradual distraction.
Methods:
: Peer-reviewed research published on the growth of the spine, lung, chest wall, and treatment of their deformities was reviewed. Treatment methods and outcomes were compared. Ranking of the levels of evidence was performed where possible.
Results:
: Most studies of these topics are Level III and IV studies, consisting of case-control studies and case series. This limitation arises because of the rarity and heterogeneity of the disorders affecting the growing spine and chest wall. The natural history of most types of spinal/chest wall deformities is not known with accuracy. Some experimental evidence informs the treatments which involve modulation of the growth of the spine. However, accurate models of the deformities themselves are lacking. Improvements in imaging and measurement offer options for more accurate patient comparison.
Conclusion:
: The natural history and results of treatment of deformities of the spine and chest wall offer much opportunity for further evidence-based research.

Vertebral Column: Regions and Curvature
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...

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
