FEMOROACETABULAR IMPINGEMENT: PREVALENCE OF RADIOGRAPHIC MORPHOLOGY IN INDIAN POPULATION, ETIOLOGY AND CLINICAL...

Area of Science:

• Orthopedics
• Radiology
• Public Health

Background:

• Femoroacetabular impingement (FAI) is a significant cause of hip and groin pain, potentially leading to early hip osteoarthritis.
• The prevalence of FAI in the Indian population remains under-documented, necessitating further research.
• Understanding FAI prevalence is crucial for early diagnosis and intervention in young adults.

Purpose of the Study:

• To determine the prevalence of radiographic FAI morphology in an Indian population.
• To analyze associated groin pain, etiological factors, and clinical management strategies for FAI.
• To establish baseline data for FAI in India for future public health initiatives.

Main Methods:

• An observational, cross-sectional study involving 550 patients aged 18-50 undergoing pelvic radiography.
• Radiographic analysis for FAI signs, with groin pain assessed using the Non-Arthritic Hip Score (NAHS).
• CT scans for symptomatic patients and multivariate logistic regression for etiological risk factor analysis.

Main Results:

• High prevalence of radiographic FAI morphology (82% of individuals, 73% of hips), with pincer morphology being predominant.
• Lateral center-edge angle was the most common finding; crossover sign was least common.
• Only 10% of hips were symptomatic, correlating with multiple radiological morphologies and CT findings; significant etiological associations were identified.

Conclusions:

• Radiographic FAI morphology is highly prevalent in the Indian population (82% individuals, 73% hips).
• CT scans accurately validated findings in symptomatic individuals.
• Identified etiological associations can guide preventive measures, and conservative management shows promising pain-free outcomes.
