Abstract

The study reports a case of 14-year-old female child who was not participating in any athletic activities, and presented with gradual onset of left side hip and groin pain since 8 months duration. Clinical and radiological evaluation showed medial-sided femur neck insufficiency fracture associated with vitamin D deficiency. Femur neck insufficiency fractures are rare entity in children; usually result from overuse injuries in athletes. Absence of athletic activities raises the suspicion of endocrine or metabolic derangement as an underlying cause of insufficiency fracture.

Key words: Femur neck, insufficiency fracture, adolescent, vitamin D deficiency.
