A chiropractic perspective on atlantoaxial instability in Down's syndrome

Area of Science:

• Neurology
• Orthopedics
• Genetics

Background:

• Down syndrome is associated with a higher prevalence of atlantoaxial instability.
• Atlantoaxial instability can result from anomalous axis formation or ligamentous laxity.
• Serious neurological complications, including death, can arise from atlantoaxial subluxation.

Purpose of the Study:

• To review current information on atlantoaxial instability in individuals with Down syndrome.
• To highlight the potential dangers of cervical spine manipulation in this population.
• To suggest guidelines for the evaluation, diagnosis, and management of atlantoaxial instability.

Main Methods:

• Literature review of existing studies and clinical guidelines.
• Analysis of the causes and consequences of atlantoaxial instability in Down syndrome.
• Discussion of current treatment modalities and potential conservative alternatives.

Main Results:

• Up to 50% of cases are linked to developmental anomalies of the axis or transverse ligament.
• Trauma or progressive atlas displacement can lead to severe neurological deficits.
• Surgical fusion is the standard treatment, with conservative chiropractic care proposed as a potential alternative in select cases.

Conclusions:

• Established standards for chiropractic adjustment in Down syndrome patients are lacking.
• Guidelines are needed to identify hazardous situations for spinal manipulation.
• Protocols for evaluating and diagnosing atlantoaxial instability are proposed to improve patient safety.
