Prevalence of late-onset tibia vara

Area of Science:

• Orthopedics
• Pediatric Endocrinology
• Public Health

Background:

• Late-onset tibia vara is a condition affecting bone alignment in adolescents.
• Rising rates of adolescent obesity are a growing public health concern.
• Understanding the prevalence of tibia vara in at-risk populations is crucial for early detection and intervention.

Purpose of the Study:

• To determine the prevalence of late-onset tibia vara in an at-risk population of adolescent males.
• To investigate the association between obesity and the development of tibia vara.
• To identify demographic factors associated with late-onset tibia vara.

Main Methods:

• A cohort of 1,117 adolescent males aged 13-19 years was screened.
• Inclusion criteria focused on individuals weighing at least 210 pounds.
• Varus alignment was assessed through physical examination and radiographic imaging.

Main Results:

• 140 obese adolescent males (80 black, 60 white) were included in the study.
• Radiographic evaluation identified two cases of late-onset tibia vara.
• Both affected individuals were black, weighed over 280 pounds, indicating a 2.5% prevalence in this specific subgroup.

Conclusions:

• The prevalence of late-onset tibia vara in obese adolescent black males is 2.5%.
• The study highlights a potential link between morbid obesity and the increased incidence of tibia vara.
• Further research is warranted to explore the etiological factors and long-term implications of this condition.
