Role of High Frequency Ultrasonography for Detection of Radiolucent Foreign Bodies and Their Surgical Management
Journal Title: International Journal of Contemporary Medical Research - Year 2016, Vol 3, Issue 1
Abstract
Introduction: Delayed presentation of foreign bodies has been reported from the developing world since many decades. They are usually missed on the initial evaluation owing to the vague history or the radiolucent nature of the presenting foreign body. Materials and Methods: This study was conducted on 44 consecutive patients reporting to our institution with a suspected retained foreign body in the musculoskeletal system and in whom standard radiography failed to demonstrate a foreign body. Ultrasound was performed using high-resolution (10 MHz) ultrasound system. After confirming the diagnosis, foreign body removal was carried out by surgical exploration. Results: Most common sites of injury was hand involved in 34% followed by foot and ankle in 23% patients. Time of presentation ranged from 1 day to 20 weeks. Predominant chief complaints of the patients were: foreign body sensation 43% patients and pain in 23% patients. Wooden splinters were most common variety of foreign body present in 48% patients followed by Nail slipper injury (rubber) present in 16% patients. Length of the foreign body as given by ultrasound ranged from 3 mm to 30 mm. Conclusion: Sonography is a safe, cost effective, portable, readily available and highly sensitive method to evaluate radiolucent foreign bodies, especially, in patients with clinical suspicious of foreign bodies that may remain undiagnosed in radiography. It also gives important information about the nature, size, depth, and relationship of foreign bodies to other structures and makes exploration easier for the surgeon.
