Residual foreign bodies are usually observed inside the body after foreign body penetration injuries. However, foreign bodies inside or near the joints are rarely encountered. In the case study included in this report, the case of a foreign body in the posterior ankle region of a 10-year-old child is presented, along with a new study highlighting the technique of its excision with hindfoot endoscopy. The visualization and capture of a foreign body within this region, and its relation to endoscopic excision, has been reported as being a support for hindfoot endoscopy. The aim of this article is to highlight the need for the provision of a low threshold arthroscopic hindfoot surgery in children who display the appropriate symptoms. The purpose of this surgery is to efficiently remove intra-articular hindfoot loose bodies and to gain functionally improved results, when compared with open techniques.
